【題目】Typing（打字）is one of the most important and basic work skills of the 21st century. 【1】 Thumbing means using one or more thumbs（拇指）to press the keys.

Most people can type between 20 and 35 words a minute. Some typists, however, can work very quickly, at more than 110 words a minute. And people’s left hand usually does 56 percent of the typing.

The most common international English keyboard is QWERTY.【2】 It is more than 140 years old. Other keyboards include QWERTZ (in Central Europe) and AZERTY (used by most French speakers in Europe). Languages with non-Roman alphabets（字母系統(tǒng)），for example, Arabic, Russian or Japanese, have their own keyboards.

The sentence “The quick brown fox jumps over the lazy dog” is often used to practice typing.【3】

Thumbing and typing can hurt you. RSI (repetitive strain injury) is the name of a medical condition you get if you type too much. 【4】Anyone who uses a computer a lot is at risk and should know about RSI.?

?

A.It gets the name from the first six letters on the top left side of the keyboard.

B.However, most people do not understand what . RSI is or how serious it can be.

C.Because mobile phones are now so popular, there is a new kind of typing - thumbing.

D.It seems that thumbing is much harder for us to learn.

E.That’s because it uses every letter of the English alphabet.

?

【答案】

【1】C

【2】A

【3】E

【4】B

【1】解析：根據(jù)下文Thumbing means using one or more thumbs（拇指）to press the keys.拇指輔行法是指一個或多個拇指按鍵，可知C選項符合語境，故答案選C。

【2】解析：根據(jù)上文The most common international English keyboard is QWERTY. 最常見的國際英語鍵盤是QWERTY鍵盤，可知A選項符合語境，故答案選A。

【3】解析：根據(jù)上文The sentence “The quick brown fox jumps over the lazy dog” is often used to practice typing.“敏捷的棕色狐貍跳過懶狗”這句話經(jīng)常被用來打字，可知E選項符合語境，故答案選E。

【4】解析：根據(jù)上下文句意的理解，可知這里是在講RSI（重復(fù)性勞損），結(jié)合選項可知B選項符合語境，故答案選A。

【題目】Have you ever had the strange feeling that you were being watched? You turned around and, sure enough, someone was looking right at you!

Parapsychologists (靈學(xué)家) say that humans have a natural ability to sense when someone is looking at them. To research whether such a “sixth sense” really exists（存在）, Robert Baker, a psychologist (心理學(xué)家) at the University of Kentucky, did two experiments.

In the first one, Baker sat behind unknowing people in public places and stared at the backs of their heads for 5 to 15 minutes. The subjects(受試者)were eating, drinking, reading, studying, watching TV, or working at a computer. Baker made sure that the people could not tell that he was sitting behind them during those periods. Later, when he questioned the subjects, almost?all of them said they had no sense that someone was staring at them.

For the second experiment, Baker told the subjects that they would be stared at from time to time from behind in a laboratory setting. The people had to write down when they felt they were being stared at and when they weren’t. Baker found that the subjects were no better at telling when they were stared at and when they weren’t.

Baker concludes that people do not have the ability to sense when they’re being stared at. If people doubt the outcome of his two experiments, said Baker, “I suggest they repeat the experiments and see for themselves.”

【1】The aim of the two experiments is to________.

A. explain when people can have a sixth sense

B. show how people act while being watched in the lab

C. study whether humans can sense when they are stared at

D. prove why humans have a sixth sense

【2】In the first experiment, the subjects_________________.

A. were told that they were stared at??? B. did nothing but sit silently

C. were stared at for 5 to 15 hours??? D. didn’t know that someone was staring at them

【3】The underlined word “outcome” in the last paragraph most probably means_______.

A. value??? B. result??? C. effort??? D. reason

【4】In the second experiment, the subjects _________.

A. could tell when they were stared at and when they weren’t.

B. could tell when they were stared at but couldn’t tell when they weren’t.

C. couldn’t tell when they were stared at but could tell when they weren’t.

D. couldn’t tell when they were stared at or when they weren’t.

【5】What can be learned from the passage?

A. People are born with a sixth sense.

B. The experiments support parapsychologists’ idea.

C. The subjects do not have a sixth sense in the experiments.

D. People have a sixth sense in all places.
