When a person walks, the movement of his head, trunk, hipbones and limbs are all reflected in changes in his body. A computer     1     these changes into a database. Later, the computers can     2     identify him according to these changes. This is a new biological identification method and it can quickly identify an examinee     3     disturbing him. It's especially suitable for use in airports and supermarkets.

     Everybody's voice is     4    . When a person's voice is recorded by an instrument, its voice frequency spectrum is called his sound print. Like a fingerprint, everybody's sound print is different. How can computers     5     his sound? First, his voice is recorded, which allows the computers to become familiar with his voice. It will then turn his sound characteristics into a     6     of digits. These digits represent the frequency, pitch and rhythm of the person’s voice. These are the     7     on which the computers can distinguish1 his voice from     8    .

     When that person needs to be identified, after he says only one word or two, the computers can identify him. The computers can even identify sounds coming     9    the wires. This will provide a     10     guarantee to electric banks and electric purchases.

     We often bring ID cards2, work cards, or driver licenses with us to prove our identity. If all these cards are forgotten or lost, how can we prove     11     we are? In fact, it's not difficult to prove whom you are, because your body     12     has identifying markers. Some are physiological features, such as fingerprints, sounds, facial types and eye color. The computer can help to identify you. Suppose your features have already been stored in the database3. To identify you, we have to take your picture with a camera and send it to a computer for     13    . First, the computer needs to reposition this picture according to the position of your eyes4, and then starts to read the message of your physiological features such as the     14     of your pupil5 to the whites of your eyes6 and the shape of his nose. Next, it seeks matching records from the database. Finally, it makes a     15    .

【小題1】B

【小題2】D

【小題3】A

【小題4】C

【小題5】C

【小題6】A

【小題7】D

【小題8】B

【小題9】D

【小題10】D

【小題11】B

【小題12】C

【小題13】A

【小題14】C

【小題15】B


解析:

【小題1】從上下文的意思判斷,作者說的是往資料庫里存儲肢體的變化的資料。存儲的英語詞是 store,所以要選 B.check( 檢查)、revise (修正) 和 modify(修改) 與上下文的意思都配不上。

【小題2】選項 A 的 nearly (不完全地)、選項 B 的 approximately (近似地)、選項C的 roughly (概略地) 都不可能與電腦的快速、準(zhǔn)確的性能聯(lián)系起來,而且約摸地辨認(rèn)也不會有實用價值。只有選 D (accurately 準(zhǔn)確地) 才符合邏輯。

【小題3】前面句子說這是一項新的生物學(xué)的辨認(rèn)技術(shù),最后一句說,這項新技術(shù)適合機(jī)場和超市使用。以此推論,這是個好的技術(shù)。能辨認(rèn)人而又不去打攪 (without disturbing) 被辨認(rèn)人的技術(shù)才是好技術(shù)。選項 A 是本題的答案。

【小題4】辨認(rèn)依靠的是被辨認(rèn)人具有的特性,每個人的聲音也有其獨特性和惟一性。所以,選項 C 的 unique(惟一的)反映了這個道理,所以是答案。

【小題5】本段前面幾句是說人的聲紋與指紋一樣,可以用來辨認(rèn)人。后面幾句介紹電腦如何利用聲紋辨認(rèn)人。所以填入"空5"的詞一定是選項 C 的 distinguish.其它三個選項提供的詞,無論用哪一個都不合適,因為后面的句子都不是回答 "How can computers hear/understand/record his sound?"這些問題的。

【小題6】在句子 "It will then turn his sound characteristics into a     ?     of digits"(然后電腦將他的聲音特征轉(zhuǎn)換為      ?     的數(shù)碼) 中,填入"空6"的詞似是相當(dāng)于漢語中的量詞。查看四個選項,只有 a series of digits (一系列數(shù)碼) 最合適。a package of (一箱的)、a line of (一行的)、a pair of (一雙的) 與 digits 都不搭配。

【小題7】從意義上分析,選項 D 的 basis 是最合適的。而且 basis 與介詞 on 也搭配,組成 on this basis (在此基礎(chǔ)上)。其它三個選項的詞不僅與上下文的意思不連貫,而且與 on 也不搭配。

【小題8】句子的意思是,電腦能夠?qū)⒛橙说穆曇襞c他人的聲音區(qū)分開來。答案是選項 D 的 another's.each other's (彼此的聲音) 和 one another's (彼此的聲音) 明顯不對。other's 也不對,如果要用, 就得是 others'.

【小題9】句子的意思是,電腦還能夠識別通過電線傳過來的聲音。through 是合理的選擇。所以,D是答案。

【小題10】本題解題的思路最好用排除法。如果選用 cleverer/tidier/smarter 與 guarantee 搭配,意思上有點怪,只有 safer guarantee (更安全的擔(dān)保) 最合理。

【小題11】電腦要證明的是我們是誰,即我們的身份,所以只能用 whom we are.B 是答案。

【小題12】body 的代詞是 it,反身代詞是 itself.句子的意思和語法都要求用反身代詞,即 itself.C是答案。

【小題13】后面的句子說電腦對輸入的人像進(jìn)行多項處理 (first, then, next, finally)。要表達(dá)"處理"這層意思的英語詞是 processing. A 是答案。

【小題14】選用 size、type 或 shape 都不行。如果用了, "your pupil to the whites of your eyes"中的 to 就與 size、type 或 shape 不搭配。只有選  ratio, 意思上和搭配上都對。ratio的用法是 ratio of…to…。

【小題15】電腦辨認(rèn)的結(jié)果一定要安全可靠,不能含糊其詞。所以,proposal, recommendation 都不會是答案。contribution (貢獻(xiàn)) 的意思與上下文接不上。所以,只有 選項B 的 decision 才是答案。

Many people like the feeling of the gentle wind in spring. Many like to see the falling leaves dancing in the wind in autumn. But sometimes, when the wind becomes a storm, it can be very destructive(具有破壞性的).

   A series of such storms struck the US last month and caused very serious damage and human pain.

Every year, major storms cause many problems around the world. There is nothing people can do to stop these powerful forces of nature. But new techniques are helping scientists to predict(預(yù)測) how, when, and where big storms will happen. The more exact scientists’ warnings are, the better people can prepare for the storms.

Predictions are improving. “We’re gotten better over the years, especially the last few years,” says Phil Klotzbach, a scientist at an American university. How is a storm formed? Even if scientists know where a storm will happen, winds can suddenly change, carrying the storm to a new direction. “For a hurricane to happen, conditions have to be just right, ” Klotzbach says.

First, the ocean water needs to be warm enough so that it evaporates and rises into the air. As it rises, the vapor(水蒸氣)cools and turns back into liquid. This process gives off heat. This produces energy like an engine that causes winds to increase. It drives the formation(形成) of a hurricane.

If wind speeds reach 40 miles per hour, the system is called a “tropical storm”(熱帶風(fēng)暴), and it gets a name. At 75 miles per hour, it becomes a hurricane.

Hurricanes that hit the US start when a thunderstorm forms off the coast of Africa. Storms also develop over tropical waters in other parts of the world.

On average, 60 or 70 storms form off Africa every year. About 10 of them get names. There are usually about six hurricanes. Two tend to be very big, with winds of 115 miles per hour or higher.

The hurricane season lasts from June to November. Ninety percent of all hurricanes hit in August, September, and October.

49. According to the passage, hurricanes usually ____.

A. form off the coast of Africa and America

B. travel at 40 miles per hour and get its name

C. cause sea winds to rise and blow over the sea

D. hit parts of the world in summer and autumn

50. The underlined word “evaporates” probably means “____”.

A. begins to move    B. gets lost    C. becomes hot      D. changes into gas

51. Which of the following about the information of a hurricane is the correct order?

a. The ocean water evaporates and goes into the air.

 b. Heat creates energy and causes winds to increase.

 c. The vapor cools.

 d. The ocean water is warm enough.

 e. The vapor changes back into liquid.

 f. This course gives out heat.

A.a, d, e, b, c, f     B.a, b, c, f, d, e  C.d, a, c, e, f, b    D.d, a, b, c, e, f

52. According to the passage, the speed of the biggest two hurricanes reaches ____.

A.115 miles per hour                 B.110 miles per hour

C.75 miles per hour                  D.95 miles per hour

New rules will let millions of Americans know where more of their food comes from.The law is known as COOL—Country of Origin Labeling.
American Congress first passed the law in 2002.Stores have had to label seafood by country of origin since 2005.But industry pressure delayed other requirements until last week.
Products that must now be labeled include fresh fruits and vegetables, muscle meats and some kinds of nuts.But the rules are complex, and many foods are excluded.For example, organ meats are free to be labeled.So are processed foods, including cooked or smoked food.
The United States has imported more and more food in recent years to save money and expand choices.Country-of-origin labeling has become more common lately but has still been limited in many stores.
Food safety is one reason why some shoppers pay close attention to where foods came from.For example, when a large number of people recently got sick from salmonella(沙門菌病), officials blamed peppers from Mexico.Yet the last big food scare involved spinach (菠菜) grown in California.But labeling is also a way for people to know they are getting what they want.Some want to buy local foods or foods from a particular country.
The country-of-origin labeling law gives stores 30 days to correct any violations that are found.Stores and suppliers that are found to be deliberately violating the law could be fined 1000 dollars per violation.Federal inspectors are not to take action to enforce the law for six months to give time for an education campaign.
Some food safety activists say they are generally pleased with the law.They call it a good step that will give people more useful information.

Read the passage carefully. Then answer the questions or complete the statements in the fewest possible words
The automobile may not be closely associated with modem American culture, but it has occupied a central role in America’s economic and social history.
No one can deny the status of Henry Ford in car history. When the first Ford Model T rolled off the assembly line in 1908, businessman Henry Ford transformed the car from a luxury attachment for the rich to an automobile product for the middle classes. The rush of cars into the community forced all levels of government to build new and better roads. Better roads fed the demand for larger, faster, more stylish vehicles, and a host of companies rushed to meet that demand.
If there was a first Golden Age of automobile, it may well have been the 1950s. It was an age of prosperity. Large, regular paychecks encouraged the public display of wealth through costly items such as new cars. Americans, moreover, needed those cars as they moved away from the cities into the suburbs, where such things as stores, jobs, and schools were seldom within walking distance. Cars became essential if people were to get to work or to the grocery store.
As Ac 1950s slipped into 1960s, it became apparent that these fashionable wheels were gas-consuming road cruisers, dangerous in an accident, and often full of faults. Under pressure from a variety of groins, the federal government required that newer models provide greater fuel efficiency and cleaner emissions. Seatbelts became standard equipment as well Rising fad prices in the 1970s, coupled with concern for the environment, made the smaller cars produced by foreign companies for European and Asian markets very popular.
The 1980s and 1990s saw an upswing in the popularity of big cars. New models including minivans and sport utility vehicles have become main products in auto dealers’ showrooms. Traffic jams on the roads have become part of the American way of life. In 1911 a horse could travel through rush-hour traffic in Los Angeles at 11 miles per hour. In 2000 a car covering the same territory at the same time of day moved at about 4 miles per hour. But perhaps that is not important. When a car is equipped with a telephone and television set, a computer, and global positioning satellite connections, it can feel just like home.
(Note: Answer the questions or complete the statements in NO MORE THAN TEN WORDS.)
【小題1】___________________made Henry Ford well-known in car history.
【小題2】That the car industry prospered in the 1950s in America resulted from ________.
【小題3】 Why were smaller cars once popular in the 1970s?
【小題4】 In today’s society, how can a car make people ignore traffic jams?

In the US and Britain, the slogan around colleges was “Save water. Shower with a friend.” Now, Wuhan University has come up with another system for the campus bathhouse. It charges students for the amount of time in a shower. Before entering the bathhouse, students pay for the amount of time they want in the shower with cash or their student ID card. The clock starts ticking the minute the tape is turned on. It pauses when a button is pressed for soap. An integrated circuit(IC) card reader at each tap shows the time. No money, no water. The benefits of the new system can be seen with the old system, which charged 1 Yuan for each person regardless of time in the shower. The university used about 320 tones of water daily under the old system, but only 160 tons now.

Many students use the new system but opinions on it are divided. Some students say it is bad because bathing had become a sort of race. Many people using it for the first time are not sure how long they need to shower. Some might be embarrassed if their time is up and they’re still covered in soap. They have to ask the bathhouse worker to help them buy extra time.

“It’s a flaw in the system that you can not buy extra time on the ID card,” said Ren, a freshman in Wuhan University. The university is also considering some students’ suggestions that they be allowed to pay after they’ve finished the shower. Not surprisingly, some are complaining about losing the hour shower. But many students say the move helps them develop a water-saving sense.

Without the time limits, most students tended to shower for 30 to an hour in the bathhouse.

Some even used the hot water to wash their clothes. “In my experience, 10-20 minutes is enough,” said Dai Zhihua, a third-year student who usually takes 8 minutes.

A similar system has been installed in other universities. Shanghai Normal University introduced it at its Fengxiang Campus in September. The bathing fee there is 0.2 Yuan per minute. One male student responded by setting a record with a two-minute shower.

1.According to the passage, which of the following is NOT true?

A. Students pay for the amount of time they want in the shower.

B. The clock times all through while the student is bathing except when the bather paused for soap.

C. If money runs out, there will be no water.

D. Having finished bathing, the student has to pay for it.

2.The underline word “flaw” (Paragraph3) most probably means______.

A. perfection       B. advantage            C. pity                 D. fault

3.Since the new system has performed, ______ of water can be saved.

A. a quarter            B. one third            C. one half             D. two thirds

4.It can be inferred from the passage that______.

A. the new operation can solve the water crisis.

B. The new operation can raise students’ environmental awareness.

C. a similar operation has been set in other universities.

D. The university has saved a lot of water by using the new system.

5.In which column can you find this passage?

 A. People.         B. Society         C. Campus Life.    D. Lifestyle.
