Adam’s dog, a golden retriever named Hans, can respond to over 150 different commands. Adam cites this fact as evidence for his claim that Hans can understand the English language.  Which of the following, if true, casts the most doubt on Adam’s claim that Hans can understand the English language?
A

Each of the 150 commands to which Hans responds involves both a spoken word in English and a distinctive hand sign.

B

Hans does not respond to the same commands when spoken to him by Adam’s French and Italian friends in their own languages.

C

Scientists have demonstrated conclusively that canine vocal chords are incapable of replicating many of the sounds used in the English language.

D

Animal behaviorists have demonstrated that even very young dogs surpass both wolves and chimpanzees—animals that are thought to be more intelligent than dogs—in the ability to understand human nonverbal communication.

E

The golden retriever is widely considered to be less intelligent than the border collie, and no border collie has ever been shown to truly understand the English language.

参考答案和解析
正确答案: D
解析:
A项揭示Hans可以理解150种不同的指令是因为狗可能对不同的手势有反应,这为狗的行为提供了另一种不同的解释,所以A项是正确的。

第5题:

For any Englishman there can never be any discussion as to who is the world's greatest writer. Only one name can possibly suggest itself to him:that of William Shakespeare.

Every Englishman has some knowledge of his work. All of us use words and phrases from Shakespeare's writings that have become a part of the English-speaking people.

Shakespeare, more perhaps than any other writer, made full use of the English language. Most of us use about five thousand words in our normal employment of English; Shakespeare in his works used about twenty-five thousand!

There is probably no better way for a foreigner (or an Englishman!) to appreciate the richness and variety of the English language than by studying the various ways in which Shakespeare uses it. Such a study is well worth the effort (it is not, of course, recommended to beginners), even though some aspects of English usage, and the meaning of many words, have changed since Shakespeare's day.

1). From the first two sentences of the passage we can conclude that ________.

A. it can't be discussed about who is the world's greatest dramatist

B. Shakespeare is regarded as the greatest writer

C. Englishmen like to discuss about who is the world's greatest writer

D. it can't be discussed about who is the world's greatest poet

2). According to the passage many English words and phrases that we use today are from _____.

A. Englishmen

B. English speaking people

C. Shakespeare's works

D. ancient people

3). To learn the richness of the English language, people should ______.

A. write and read more

B. be glad to be a foreigner

C. learn from an English man

D. read Shakespeare's plays

4). The author does not suggest beginners reading Shakespeare's plays probably because _____.

A. only Englishmen can understand his plays

B. some of English usage and the meaning of many words have changed

C. the works are too difficult for a beginner

D. the works are for native speakers

5). In this passage the author wants to _______.

A. tell how great a writer Shakespeare is

B. tell that some aspects of English usage have changed since Shakespeare's day

C. tell that some English words are out of use now

D. show the richness of English language

第8题:

Adam Smith, a writer in the 1770s, was the first person to see the importance of the division of labor and to explain part of its advantages. He gives as an example the process by which pins were made in England.

"One man draws out the wire, another strengthens it, a third cuts it, a fourth points it, a fifth grinds it at the top to prepare it to receive the head. To make the head requires two or three distinct operations. To put it on is a separate operation, to polish the pins is another. And the important business of making pins is, in this manner, divided into about eighteen distinct operations, which in some factories are all performed by different people, though in others the same man will sometimes perform. two or three of them."

Ten men, Smith said, in this way, turned out twelve pounds of pins a day or about 4 800 pins a piece. But if all of them had worked separately and independently without division of labor, they certainly could not turn out any pin, each of them have made twenty pins in a day and perhaps not even one.

There can be no doubt that division of labor is an efficient way of organizing work. Fewer people can make more pins. Adam Smith saw this but he also took it for granted that division of labor is in itself responsible for economic growth and development and that it accounts for the difference between expanding economies and those that stand still. But division of labor adds nothing new; it only enables people to produce, more of what they already have.

According to the passage, Adam Smith was the first person to______.

A.take advantage of the division of labor

B.explain the causes of the division of labor

C.understand the effects of the division of labor

D.introduce the division of labor into England
