1、What Do Dreams Tell Us?
Why do we dream? Do dreams have meanings? These are questions which have troubled man for thousands of years. The oldest surviving book on the interpretation of dreams is Egyptian and is nearly 4,000 years old. In ancient Greece, it was thought that people who were ill could be cured by telling their dreams. They would relate their dreams to their doctors who would tell them what they meant and then give them medicine to make them well. The ancient Chinese believed that if a pregnant woman dreamed of a bear, she would have a son, and if she dreamed of a snake, she would have a daughter. There are many stories about dreams foretelling (預(yù)言) the future.
We certainly do not now believe that dreams foretell the future. Most scientists believe that dreams are based on events in our own life and on our feelings. The events are usually very recent, mostly within the last two days. Our emotions, on the other hand our wishes, hopes and fears may go back many years, even to early childhood.
In a dream, events are altered. A dream may contain parts of many real-life events. Most importantly, something that cannot be shown directly may be shown indirectly. For example, you might dream of driving a large car. This could mean not that you want to have a larger car, but that you desire power, and maybe you want to control other people. Again, you may dream that you are an actor in a play. The play is about to start, but you have completely forgot your lines. This dream may seem strange because you are not interested in acting, and you never want to be in a play. But the dream may mean that you have some other problem that you feel is too difficult for you to solve.
Psychologists believe that dreams may be helpful to us. Indeed, people who have been allowed to sleep in experiments, but not allowed to dream, have become anxious and restless. And when they are later allowed to sleep as much as they like, they dream more than ever to make us for the lost "dream time".
Paragraph 2 ______
【單選題】

A.Structure and interpretation of a dream

B.Ancient views on dreams

C.Babies dream less than older children

D.Dreaming may be good for our health

E.Dreams can not foretell the future

F.Healthy people do not dream

正確答案:E

答案解析:第二段主題句為第一句：We certainly do not now believe that dreams foretell the future. 現(xiàn)在的我們一定不會(huì)相信夢(mèng)能夠預(yù)見未來。E選項(xiàng)Dreams can not foretell the future（夢(mèng)不能預(yù)言未來）與其意思一致，故E為正確答案。

2、Animal's "Sixth Sense"
A tsunami was triggered by an earthquake in the Indian Ocean in December, 2004. It killed tens of thousands of people in Asia and East Africa, Wild animals, however, seem to have escaped that terrible tsunami. This phenomenon adds weight to notions that they possess a "sixth sense" for disasters, experts said.
Sri Lankan Wildlife officials have said the giant waves that killed over 24,000 people along the Indian Ocean island's coast clearly ______ wild beasts, with no dead animals found.
"No elephants are dead, not even a dead rabbit. I think animals can sense disaster. They have a sixth sense. They know when things are happening" H. D. Ratnayake, deputy director of Sri Lanka's Wildlife Department, said about one month after the tsunami attack. The waves washed floodwaters up to 2 miles inland at Yala National Park in the ravaged southeast, Sri Lanka's biggest wildlife reserve and home to hundreds of wild elephants and several leopards.
"There has been a lot of scientific evidence about dogs barking or birds migrating before volcanic eruptions or earthquakes. But it has not been proven," said Matthew van Lierop, an animal behavior assistant at Johannesburg Zoo. "There have been no specialist studies because you can't really test it in a lab or field setting," he told Reuters. Other authorities concurred with this assessmetn.
"Wildlife seem to be able to pick up certain phenmenon, especially birds. There are many reports of birds detecting impending disasters," said Clive Walker, who has written several books on African wildlife.
Animals certainly rely on the known senses such as smell or hearing to avoid danger such as predators. The notion of an animal "sixth sense" -or some other mythical power-is an enduring one which the evidence on Sri Lanka's ravaged coast is likely to add to. The Romans saw owls as omens of impending disaster and many ancient cultures viewed elephants as sacred animals endowed with special powers or attributes.

3、Cell Phone Lets Your Secret Out
Your cell phone holds secrets about you. Besides the names and numbers that you've programmed into it, traces of your DNA linger on the device, according to a new study.
DNA is genetic material that appears in every cell. Like your fingerprint, your DNA is unique to you- ______ you have an identical twin. Scientists today routinely analyze DNA in blood, saliva, or hair left behind at the scene of a crime. The results often help detectives identify criminals and their victims. Your cell phone can reveal more about you than you might think.
Meghan J. McFadden, a scientist at McMaster University in Hamilton, Ontario, heard about a crime in which the suspect bled onto a cell phone and later dropped the device. This made her wonder whether traces of DNA lingered on cell phones even when no blood was involved. So she and colleague Margaret Wallace of the City University of New York analyzed the flip open phones of 10 volunteers. They used swabs to collect invisible traces of the users from two parts of the phone: the outside, where the user holds it, and the speaker, which is placed at the user's ear.
The scientists scrubbed the phones using a solution made mostly of alcohol. The aim of washing was to remove all detectable traces of DNA. The owners got their phones back for another week. Then the researchers collected the phones and repeated the swabbing of each phone once more.
The scientists discovered DNA that belonged to the phone's speaker on each of the phones. Better samples were collected from the outside of each phone, those swabs also picked up DNA that belonged to other people who had apparently also handled the phone. Surprisingly, DNA showed up even in swabs that were taken immediately after the phones were scrubbed. That suggests that washing won't remove all traces of evidence from a criminal's device. So cell phones can now be added to the list of clues that can clinch a crime scene investigation.
【單選題】

C.although

D.still

正確答案:B

答案解析:上文的意思是：如同指紋，你的DNA是獨(dú)一無二的。因此，此處必須選擇unless，其他選擇均不符合句義，也違背了我們對(duì)DNA的基本常識(shí)。

4、Better Control of TB Seen if a Faster Cure is Found
The World Health Organization estimates that about one-third of all people are infected with bacteria that cause tuberculosis. Most times, the infection remains inactive. But each year about eight million people develop active cases of TB, usually in their lungs. Two million people die of it. The disease has increased with the spread of AIDS and drug-resistant forms of tuberculosis.
Current treatments take at least six months. Patients have to take a combination of several antibiotic drugs daily. But many people stop as soon as they feel better. Doing that can lead to an infection that resists treatment. Public health experts agree that a faster-acting cure for tuberculosis would be more effective. Now a study estimates just how effective it might be. A professor of international health at Harvard University led the study. Joshua Salomon says a shorter treatment program would likely mean not just more patients cured. It would also mean fewer infectious patients who can pass on their infection to others.
The researchers developed a mathematical model to examine the effects of a two-month treatment plan. They tested the model with current TB conditions in Southeast Asia. The scientists found that a two-month treatment could prevent about twenty percent of new cases. And it might prevent about twenty-five percent of TB deaths. The model shows that these reductions would take place between two thousand twelve and two thousand thirty. That is, if a faster cure is developed and in wide use by two thousand twelve.
The World Health Organization ______the DOTS program in nineteen ninety. DOTS is Directly Observed Treatment, Short-course. Health workers watch tuberculosis patients take their daily pills to make sure they continue treatment.
Earlier this year, an international partnership of organizations announced a plan to expand the DOTS program. The ten-year plan also aims to finance research into new TB drugs. The four most common drugs used now are more than forty years old. The Global Alliance for TB Drug Development says its long-term goal is a treatment that could work in as few as ten doses.
【單選題】

A.developed

B.invented

C.delayed

D.refused

正確答案:A

答案解析:空白處的上一句實(shí)際上也起到了提示作用，可以推測(cè)，本句應(yīng)該是“制訂DOTS計(jì)劃”，而4個(gè)選項(xiàng)中只有A有“制訂”的意思，計(jì)劃也不可能是“發(fā)明”，從上下文分析，更不可能是“推遲”或“拒絕”。

5、Inventor of LED
When Nick Holonyak set out to create a new kind of visible lighting using semiconductor alloys, his colleagues thought he was unrealistic. Today, his discovery of light-emitting diodes, or LEDs, are used in everything from DVDs to alarm clocks to airports. Dozens of his students have continued his work, developing lighting used in traffic lights and other everyday technology.
On April 23,2004, Holonyak received the $500,000 Lemelson-MIT Prize at a ceremony in Washington. This marks the lOth year that the Lemelson-MIT Program at the Massachusetts Institute of Technology (MIT) has given the award to prominent inventors. "Anytime you get an award big or little. It's always a surprise. " Holonyrak said. Holonyak, 75, was a student of john Bardeen, an inventor of the transistor, in the early 1950s. After graduate school, Holonyak worked at Ben Labs. He later went to General Electric, where he invented a switch now widely used in house dimmer switches.
Later, Holonyak started looking into how semiconductors could be used to generate light. But while his colleagues were looking at how to generate invisible light, he wanted to generate visible light. The LEDS he invented in 1962 now last about 10 times longer than incandescent bulbs, and are more environmentally friendly and effective.
Holonyak, now a professor of electrical and computer engineering and physics at the University of Illinois, said he suspected that LEDs would become as commonplace as they are today, but didn't realize how many uses they would have.
"You don't know in the beginning. You think you're doing something important. You think it's worth doing, but you really can't tell what the big payoff is going to be, and when, and how. You just don't know, "he said.
The Lemelson. MIT Program also recognized Edith Flanigen, 75, with the $100,000 Lemelson-MIT Lifetime Achievement Award for her work on a new generation of "molecular sieves", that can separate molecules by size.
The Lemelson-MIT Prize has a history of over 100 years.
【單選題】

A.Right

B.Wrong

C.Not mentioned

正確答案:B

答案解析:根據(jù)主題句內(nèi)容判斷Lemelson-MIT獎(jiǎng)成立的時(shí)間是1994年，因此問題句中說的“Lemelson-MIT獎(jiǎng)有100多年的歷史”與原文內(nèi)容矛盾。

D.an angel

正確答案:A

答案解析:monster:怪獸；beast:野獸，這兩個(gè)詞意思接近；ghost:魔鬼、幽靈；giant：巨人；angel:天使。

7、How to Be a Successful Businessperson
Have you ever wondered why some people are successful in business and others are not? Here's a story about one successful businessperson. He started out washing dishes and today he owns 168 restaurants.
Zubair Kazi was born in Bhatkal, a small town in southwest India. His dream was to be an airplane pilot, and when he was 16 years old, he learned to fly a small plane.
At the age of 23 and with just a little money in his pocket, Mr. Kazi moved to the United States. He hoped to get a job in the airplane industry in California. Instead, he ended up working for a company that rented cars.
While Mr. Kazi was working at the car rental(租賃的) company, he frequently ate at a nearby KFC restaurant. To save money on food, he decided to get a job with KFC. For two months, he worked as a cook's assistant. His job was to clean the kitchen and help the cook. "I didn't like it," Mr. Kazi says, "but I always did the best I could."
One day, Mr. Kazi's two co - workers failed to come to work. That day, Mr. Kazi did the work of all three people in the kitchen. This really impressed the owners of the restaurant.
A few months later, the owners needed a manager for a new restaurant. They gave the job to Mr. Kazi. He worked hard as the manager and soon the restaurant was making a profit.
A few years later, Mr. Kazi heard about a restaurant that was losing money. The restaurant was dirty inside and the food was terrible. Mr. Kazi borrowed money from a bank and bought the restaurant. For the first six months, Mr. Kazi worked in the restaurant from 8 a. m. to 10 p. m. , seven days a week. He and his wife cleaned up the restaurant, remodeled the front of the building, and improved the cooking. They also tried hard to please the customers. If someone had to wait more than ten minutes for their food, Mrs. Kazi gave them a free soda. Before long the restaurant was making a profit.
A year later, Mr. Kazi sold his restaurant for a profit. With the money he earned, he bought three more restaurants that were losing money. Again, he cleaned them up, improved the food, and retrained the employees. Before long these restaurants were making a profit, too.
Today Mr. Kazi owns 168 restaurants, but he isn't planning to stop there. He's looking for more poorly managed restaurants to buy. "I love it when I go to buy a restaurant and find it's a mess," Mr. Kazi says. "The only way it can go is up. "
Mr. Kazi decided to work with KFC to ______.【單選題】

A.learn how to cook

B.save money for a car

C.save money on food

D.learn how to run a restaurant

正確答案:C

答案解析:本題難度不大，也是送分題，答案依據(jù)是這一句：To save money on food，he decided to get a job with KFC.

8、A Great Quake Coming?
Everyone lives in San Francisco knows that earthquakes are common in the Bay Area and they can devastate. In 1906, for example, a major quake destroyed about 28000 buildings and killed hundreds, perhaps thousands of people. Residents now wonder when will the next "Big One" strike. It's bound to happen someday. At least seven active fault(斷層) lines run through the San Francisco area. Faults are places where pieces of Earth's crust (地殼) slide past each other. When these pieces slip, the ground shakes.
To prepare for that day, scientists are using new techniques to reanalyze the 1906 earthquake and predict how bad the damage might be when the next one happens.
One new finding about the 1906 quake is that the San Andreas Fault split apart faster than scientists had assumed at the time. During small earthquakes, faults rupture(斷裂) about 2.7 kilometers persecond. During bigger quakes, however, ruptures can happen faster than 3.5 kilometers persecond.
At such high speeds, massive amounts of pressure build up, generating underground waves that can cause more damage than the quake itself. Lucky for San Francisco, these pressure pulses (脈沖) traveled away from the city during the 1906 event.
Looking ahead, scientists are trying to predict when the next major quake will occur. Records show that earthquakes were common before 1906. Since then, the area has been relatively quiet. Patterns in the data, however, suggest that the probability of a major earthquake striking the Bay Area before 2032 is at least 62 percent.
New buildings in San Francisco are quite safe in case of future quakes. Still, more than 84 percent of the city's buildings are old and weak. Analyses suggest that another massive earthquake would cause extensive damage.
People who live there today tend to feel safe because San Francisco has remained pretty quiet for a while. According to the new research, however, it's not a matter that whether "the Big One" will hit here. It's just a matter of when.
A major earthquake striking San Francisco someday is inevitable.
【單選題】

A.Right

B.Wrong

C.Not mentioned

正確答案:A

答案解析:本題有一定難度，需要認(rèn)真吃透句意，做好判斷。答案依據(jù)在第五段。第五段最后一句：the probability of a major earthquake striking the Bay Area before 2032 is at least 62 percent.談到在2032年前海灣地區(qū)發(fā)生大地震的可能性至少是62%，說明概率很高，所以本題正確，答案是A。

9、The Book of Life
So far, scientists have named about 1.6 million living species, and that's a just a fraction of that probably exists on Earth. With so many plants, animals and other creatures coveting the planet, it can be tough to figure out what type of spider is moving up your leg or what kind of bird is flying by.
A soon - to - be - started Web site might help. An international team of researchers has announced the creation of Web - based Encyclopedia of life( EOL). The project aims to catalog every species on Earth in a single, easy - to - use reference guide.
To get the encyclopedia started, the creators will use information from scientific databases that already exist. And eventually, in special sections of the site, nonscientist with specialized knowledge will get to join in. Bird - watchers, for example, will be able to input which bird they've seen and where. The technology for this kind of tool has only become available.
As the EOL develops, you might find it useful for school projects. The site will feature special pages for kids who are studying ecosystems (生態(tài)系統(tǒng)) in their neighborhoods. To make sure the encyclopedia is accurate, scientists will review much of the information added to it. People who visit the site will be able to choose to leave out pages that haven't been reviewed.
Another convenient feature of the EOL is that you'll be able to pick the level of detail you want to see to match your interest, age and knowledge. If you wanted to learn about bears for a science class report, for example, you could use the "novice" setting to get basic information about the animals. On the "expert" setting, on the other hand, you could get much more detailed information about the history, literature and exploration of bears.
It now takes years for scientist to collect all the data they need to describe and analyze species. The creator of the Encyclopedia of Life hope that their new tool will speed up that process.
Which of the following statement is NOT true? ______【單選題】

A.The EOL will be beneficial to school kids with its development.

B.Scientists will review every piece of the information added to EOL.

C.Scientists have cataloged only a small part of the living species.

D.People with different interests and knowledge will in a way find EOL useful.

正確答案:B

答案解析:本題有一定難度，需要通讀全文，尋找答案依據(jù)。答案依據(jù)主要在文章第四段倒數(shù)第二句：To make sure the encyclopedia is accurate．scientists will review much of the information added to it．顯然，科學(xué)家是review much of the information，而不是every piece of the information，選項(xiàng)B項(xiàng)和原文句意不符，是答案。

10、Seeing Red Means Danger Ahead
The color red often means danger and by paying attention, accidents can be prevented. In the future, the color red also may help prevent danger at construction sites. Thanks to new work by engineers, bridge supports or other kinds of materials, could one day contain a color - changing material. It will turn red before a structure collapses or falls apart.
The secret behind the color - changing material is a particular type of molecule (分子). A molecule is a group of atoms (原子) held together by chemical bonds. Molecules come in all shapes and sizes and make up everything you can see, touch or feel. How a molecule behaves depends on what kinds of atoms it contains and how they're held together.
When a polymer (聚合物) containing a color - changing molecule called a mechanophore (機(jī)械響應(yīng)性聚合物) is about to break, it produces a color. When a polymer with mechanophore molecules becomes "injured" or weak, one of the mechanophore bonds _____ and the material turns red. "It's a really simple detection method," says Nancy Sottos, one of the scientists who worked on the project. Sottos and her team tested the color - changing polymers in their lab. The test results proved encouraging.
There is a way to get rid of the red color light. When a bright light is shone on the mechanophore, the broken bond is fixed and the red color disappears. Thus "self - healing" may be a problem for engineers. They need to use the color - changer in big construction projects that will be outside, under sunlight. And sunlight will make the mechanophore's warning system useless.
Sottos and her fellow scientists still have a lot of work to do before the color - changing molecules can be used outside the lab.
