If you are like most people, your intelligence varies from season to season. You are probably a lot sharper in the spring than you are at any other time of the year. A well-known scientist, Ellsworth Huntington (1876-1937), concluded from other men's work and his own among people in different climates that climate and temperature have a definite effect on our mental abilities. He found that cool weather is much more favorable for creative thinking than summer heat. This does not mean that all people are less intelligent in the summer than they are during the rest of the year. It does mean, however, that the mental abilities of large numbers of people tend to be lowest in the summer.
Spring appears to be the best period of the year for thinking. One reason may be that in the spring man's mental abilities are affected by the same factors that bring about great changes in all nature. Fall is the next-best season, then winter. As for summer, it seems to be a good time to take a long vacation from thinking!
1). Huntington based his conclusions on ___________.
A. work with people in different climates
B. records of temperature changes
C. records of change in his own intelligence
D. all of the above
2). Ellsworth Huntington decided that climate and temperature have _________.
A. a great effect on everyone's intelligence
B. no effect on people's intelligence
C. effect on only a few people's intelligence
D. some effect on most people's intelligence
3). One possible reason why spring is the best season for thinking is that ___________.
A. there are some things making all nature different from before
B. it is neither too warm nor too cold
C. it is more natural for the development of mental abilities
D. it lasts longer than the other seasons
4). The two best seasons for thinking seem to be _____________.
A. winter and summer
B. fall and winter
C. spring and fall
D. summer and spring
5). According to the passage above, vacations from thinking should be taken ___________.
A. as seldom as possible
B. during spring and fall
C. several times throughout the year
D. during the summer
第4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
