1、An Intelligent CarDriving needs sharp eyes, keen ears, quick brain, ａｎｄ　coordination between hands ａｎｄ　the brain. Many human drivers have all. these ａｎｄ　can control a fast-moving car. But how does an intelligent car control itself ?There is a virtual driver in the smart car. This virtual driver has "eyes," "brains", "hands" ａｎｄ　"feet", too. The mini-cameras on each side of the car are his "eyes," which observe the road ａｎｄ　conditions ahead of it. They watch the traffic to the car\'s left ａｎｄ　right. There is also a highly automatic driving system in the car. It is the built-in computer, which is the virtual driver\'s "brain". His "brain" calculates the speeds of ______ moving cars near it ａｎｄ　analyzes their positions. Basing on this information, it chooses the right line fｏｒthe intelligent cars, ａｎｄ　gives instructions to the "hands" ａｎｄ　"feets" to act accordingly. In this way, the virtual driver controls his car. What is the virtual driver\'s best advantage? He reacts rapidly. The mini-cameras are sending images continuously to the "brain". It completes the processing of the images within 100 milliseconds. However, the world\'s best driver at least needs one second to react. Besides, when he takes action, he needs one more second. The virtual driver is really wonderful. He can reduce the accident rate. considerably on expressway. In this case, can we let him have the wheel at any time ａｎｄ　in any place? Experts warn that we cannot do that just yet. His ability to recognize things is still limited. He can now only drive an intelligent car on expressways. 【單選題】

A.another

B.other

C.each other

D.one another

正確答案:B

答案解析:選項B和C都是“彼此、相互”，互為近義詞，所以相互排除掉；空白后出現的是復數名詞(cars)，因此答案是B（another修飾可數名詞的單數）。

2、Meet Your MemoryMemory is something that cannot be seen, touched ｏｒweighed. It is thought to be abstract. It is a ｓｅｔof skills rather than an object. Neither is there a single standard fｏｒjudging a good ｏｒpoｏｒmemory. There are a number of different ways in which a person may have a "good" memory.Memory is generally viewed as consisting of three stages: (1) acquisition refers to learning the material； (2) storage refers to keeping the material in the blain until it is needed； ａｎｄ　(3) retrieval (提取) refers to getting the material back out when it is needed.Memory consists of at least two different processes: short-term memory ａｎｄ　long-term memory. Short-term memory has a limited capacity ａｎｄ　a rapid forgetting rate. Its capacity can be increased by chunking (組成大塊), ｏｒgrouping separate bits of information into larger chunks. Long-term memory has an almost unlimited capacity.One measure of memory is recall, which requires you to produce information by searching the memory fｏｒit. In aided recall, you are given cues (提示) to help you produce the information. In free-recall learning, you recall the material in any order； in serial learning, you recall it in the ｏｒｃｅｒit was presented； ａｎｄ　in paired-associate learning, you learn pairs of words so that when the first word is given, you can recall the second word. A second measure of memory is recognition in which you do not have to produce the information from memory, but must be able to identify it when it is presented to you. In a third measure of memory, relearning, the difference between how long it took to learn the material the first time ａｎｄ　how long it takes to learn it again indicates how much you remember. Relearning is generally a more sensitive measure of memory than is recognition because relearning shows retention (保持) while recognition does not. Recognition is generally a more sensitive measure than recall.Paragraph 3 ______.【單選題】

A.Why do we forget things?

B.How do we measure memory?

C.What are the stages memory consists of?

D.What is the difference between short-term memory ａｎｄ　long-term memory?

E.What is memory?

F.Who may have a poｏｒmemory?

正確答案:D

答案解析:第三段沒有主題句，主要講述了兩種不同的記憶過程，即短期記憶和長期記憶，并分別從記憶儲存量和時間兩方面進行對比。D選項What is the difference between short-term memory ａｎｄ　long-term memory?（短期記憶和長期記憶有什么不同？）與其意思一致，故D為正確答案。

3、The policemen acted quickly because lives were at stake.【單選題】

A.in danger

B.in difficulty

C.in despair

D.out of control

正確答案:A

4、The GuitarThe Museum of Fine Arts in the eastern city of Boston recently began showing a collection of guitars. The exhibit is called Dangerous Curves: The Art of the Guitar. It shows how the instrument developed during the past four centuries. Probably no other musical instrument is as popular around the world as the guitar. Musicians use the guitar fｏｒalmost every kind of music. Country ａｎｄ　western music would not be the same without a guitar. The traditional Spanish folk music called Flamenco could not exist without a guitar. The sound of American blues music would not be the same without the sad cry of the guitar. ａｎｄ　rock ａｎｄ　roll music would almost be impossible without this instrument. Music experts do not agree about where the guitar first was played. Most agree it is ancient. Some experts say an instrument very much like a guitar was played in Egypt more than a thousａｎｄ　years ago. Some other experts say that the ancestｏｒof the modern guitar was brought to Spain from Persia sometime in the twelfth century. The guitar continued to develop in Spain. In the seventeen-hundred it became similar to the instrument we know today. Many famous musicians played the instrument. The famous Italian violinist Niccolo Paganinni played ａｎｄ　wrote music fｏｒthe guitar in the early eighteen hundred. Franz Schubert used the guitar to write some ofhis famous works. One guitar in the Boston Fine Arts display was played by Les Paul. It is a very old electric guitar. Mister Parl began experimenting with ways to make an electric guitar in the nineteen-thirties. The Gibson Guitar Company began producing its famous Les Parl Guitar in 1952. The instrument has the same shape ａｎｄ　the same six strings as the traditional guitar, but it sounds very different. The guitar has always been important to blues music. The electric guitar Mister Paul helped develop made modern blues music possible. There have been many great blues guitarists. Yet, music experts say all blues guitar players are measured against one man ａｎｄ　his famous guitar. That man is B-B King. Every blues fan knows that years ago B-B King named his guitar Lucille. Lucille is so important to American music that the Smithsonian Institution in Washington D-C has asked fｏｒit. They want to display the large, beautiful black guitar in one of the museums because it is a part ofAmerican culture. The guitar exhibit is called Dangerous Curve, because it displays all kinds of damages guitar has done to people. 【單選題】

5、The town is famous fｏｒits magnificent buildings.【單選題】

A.high - rise

B.modern

C.ancient

D.splendid

正確答案:D

6、The Hurricane1. A hurricane (颶風) is a tropical storm with winds that have reached a constant speed of 74 miles per hour. Hurricane winds blow in a large spiral(螺旋) around a relative calm center known as the "eye". The "eye" is generally 20 to 30 miles wide, ａｎｄ　the storm may extend outward 400 miles. As a hurricane nears land, it can bring heavy rains, high winds ａｎｄ　storm surges(風暴潮). The storm surges ａｎｄ　heavy rains can lead to flooding.2. Hurricanes are given a different label, depending on where they occur. If they begin over the North Atlantic Ocean, the Caribbean Sea, The Gulf of Mexico, ｏｒthe Northeast Pacific Ocean, they are called hurricanes. Similar storms that occur in the Northwest Pacific Ocean west of the Internaional Date Line are called typhoons near Australia ａｎｄ　in the Indian Ocean, they are referred to as tropical cyclones(龍卷風).3. When a hurricane hits land, it can do great damage through its fierce winds, heavy rains, inland(內陸的) flooding ａｎｄ　huge waves crashing on to the shore. During a hurricane, homes, businesses ａｎｄ　public buildings may be damaged ｏｒdestroyed, roads ａｎｄ　bridges can be washed away. A powerful hurricane can kill more people ａｎｄ　destroy more property than any other natural disaster. Fishermen are at special risk from hurricanes as they may be at sea when a hurricane arrives ａｎｄ　not be able to get to a safe harbｏｒif they do not receive adequate warning.4. If a hurricane is comming in your area, the most important thing is to stay calm ａｎｄ　find shelter immediately. Go to your safe room. If you do not have one, stay indoors during the hurricane ａｎｄ　go to a safer place near the center of your home. Cover yourself with a blanket ａｎｄ　be sure to keep away from windows ａｎｄ　glass doors, because if the glass breaks it’s really dangerous. Do not be fooled if there is lull(暫停), it could be the eye of the storm—winds will pick up again.Paragraph 3 ______【單選題】

A.Where do hurricanes usually happen?

B.What damages can a hurricane cause?

7、Breastfeeding Can Cut Cardiovascular RiskBreastfeeding can reduce the risk of a heart attack ｏｒstroke later in life ａｎｄ　could prevent hundreds of ______ of deaths each year, researchers said on Friday. Babies who are breastfed have fewer childhood infections ａｎｄ　allergies ａｎｄ　are less prone to obesity. British scientists have now shown that breastfeeding ａｎｄ　slow growth in the first weeks ａｎｄ　months of life has a protective effect against cardiovascular disease. "Diets that promote more rapid growth put babies at risk many years later in terms of raising their blood pressure, raising their cholesterol ａｎｄ　increasing their tendency to diabetes ａｎｄ　obesity-the four main risk factors fｏｒstroke ａｎｄ　heart attack." said ProfessｏｒAlan Lucas of the Institute of Child Health in London. "Our evidence suggests that the reason why breast-fed babies do better is because they grow more slowly in the early weeks."Lucas said the effects of breastfeeding on blood pressure ａｎｄ　cholesterol later in life are greater than anything adults can do to control the risk factors fｏｒcardiovascular disease, other than taking drugs. An estimated 17 million people die of cardiovascular disease, particularly heart attack ａｎｄ　strokes, each year, according to the World Health Organization. Lucas ａｎｄ　his colleagues compared the health of 216 teenagers who as babies had either been breastfed ｏｒgiven different nutritional baby formulas\' They reported their findings in The Lancet medical journal. The teenagers who had been breastfed had a 14 percent lower ratio of bad to good cholesterol ａｎｄ　lower concentrations of a protein that is a marker fｏｒcardiovascular disease risk. The researchers also found that regardless of the child\'s weight at birth, the faster the infants grew in the early weeks ａｎｄ　months of life, the greater was their later risk of heart disease ａｎｄ　stroke. The effect was the same fｏｒboth boys ａｎｄ　girls. "The more human milk you have in the newborn period, the lower your cholesterol level is, the lower your blood pressure is 16 years later, "Lucas said. 【單選題】

A.hundreds

B.thousands

C.millions

D.numbers

正確答案:B

答案解析:hundreds ofthousands of是固定搭配，表示“成千上萬”之意。

8、Black HolesMost scientists agree that black holes exist but are nearly impossible to locate. A black hole in the universe is not a solid object, like a planet, but it is shaped like a sphere (球體). Astronomers (天文學家) think that at the center of a black hole there is a single point in space with infinite (無限的) density (稠密).This single point is called a singularity (奇點). If the singularity theory is correct, it means that when a massive star collapses, all the material in it disappears into the singularity. The center of a black hole would not really be a hole at all, but an infinitely dense point. Anything that crosses the black hole is pulled in by its great gravity.Although black holes do exist, they are difficult to observe. These are the reasons,?No light ｏｒanything else comes out of black holes. As a result, they are invisible to a telescope.?In astronomical terms, black holes are truly. Fｏｒexample, a black hole formed by the collapse of a giant star would have an event horizon (視界) only 18 miles across.?The nearest black holes would be dozens of light years away from Earth. One light year is about 6 trillion (萬億) miles. Even the most powerful telescopes could not pick out an object so small at such a great distance.In 1994 the Hubble Space Telescope provided evidence that black holes exist. There are still answers to be found, however, so black holes remain one of the mysteries of the universe. (2007年)The nearest black holes are hundreds of light years away from us.【單選題】

A.Right

B.Wrong

C.Not mentioned

正確答案:B

答案解析:題干大意：離我們最近的黑洞也有幾百光年。用中心詞nearest定位，原文倒數第二段提到：The nearest black holes would be dozens of light years away from Earth. 離地球最近的黑洞有幾十光年(dozens)，而不是“hundreds”。故答案選B。

9、What Do Dreams Tell Us?Why do we dream? Do dreams have meanings? These are questions which have troubled man fｏｒthousands 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. Fｏｒexample, 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 actｏｒin 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 fｏｒyou 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 fｏｒthe lost "dream time".Paragraph 3 ______.【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 fｏｒour health

E.Dreams can not foretell the future

F.Healthy people do not dream

正確答案:A

答案解析:第三段主題句為第一句：In a dream，events are altered. 夢中發生的事是不斷變換著的。其所隱含的意義也不同。A選項Structure ａｎｄ　interpretation of a dream（夢的結構與闡釋）與其意思相符，故A為正確答案。

10、Sharing SilenceDeaf teenagers Orlando Chavez ａｎｄ　German Resendiz have been friends since kindergarten (幼兒園). Together the two boys, who go to Escondido High School in California, have had the difficult job of learning in schools where the majority of the students can speak ａｎｄ　hear.Orlando lost his hearing at the age of one. German was born deaf, ａｎｄ　his parents moved from Mexico to find a school where he could learn sign language. He met Orlando on their first day of kinder garten."We were in a special class with about 25 other deaf kids," German remembered. "Before then, I didn\'t know I was deaf ａｎｄ　I was different.""Being young ａｎｄ　deaf in regular classes was very hard," signs Orlando. "The other kids didn\'t understａｎｄ　us ａｎｄ　we didn\'t understａｎｄ　them. But we\'ve all grown up together, ａｎｄ　today, I\'m popular because I\'m deaf. Kids try to communicate with me."Some things are very difficult fｏｒthe two boys. "We can\'t talk on the phone, so if we need help, we can\'t call an emergency service," German signs. "ａｎｄ　we can\'t ｏｒｃｅｒfood in a drive - thru."Despite of their difficulties, the two boys have found work putting food in bags at a local supermarket.They got their jobs through a "workability" program, designed fｏｒteenagers from local schools with different types of learning disabilities.German has worked in the supermarket since August, ａｎｄ　Orlando started in November."The other people who work here nave been very nice to us," Orlando signs. "They even sign sometimes. At first, we were nervous, but we\'ve learned a lot ａｎｄ　we\'re getting better."The opportunity to earn money has been exciting, both boys said. After high school, they hope to attend the National Technical Institute fｏｒthe Deaf in New York.Orlando ａｎｄ　German have been ______.【單選題】

A.to Mexico together

B.deaf since they were born

C.to different high schools

D.friends since they were very young
