“Look at these tracks. It _______ be a wolf.” “Don’t be so sure. I think it _______ be a fox.”

A. must; could       B. may; might  C. need; must    D. could; need

A


解析:

根據(jù) Don’t be so sure 可知前面一空應填must。第二空填的could表示推測,雖為過去式形式,但表示現(xiàn)在意義,語氣較委婉,它與表推測的 can 主要用于否定句和疑問句不同,它可以用于肯定陳述句

科目:高中英語 來源:黑龍江省哈三中2010屆高三上學期期末考試 題型:閱讀理解


Now let us look at how we read.When we read a printed text, our eyes move across a page in short, rough movement.We recognize words usually when our eyes are still when they fixate(凝視).Each time they fixate, we see a group of words.This is known as the recognition span or the visual span.The length of time of which the eyes stop ---the duration of the fixation ----varies considerably from person to person.It also varies within one person according to his purpose in reading and his familiarity with the text.Furthermore, it can be affected by such factors as lighting and tiredness.
Unfortunately, in the past, many reading improvement courses have concentrated too much on how our eyes move across the printed page.As a result of this misleading emphasis on the purely visual aspects of reading, numerous exercises have been devised to train the eyes to see more words at one fixation.For instance, in some exercises, words are flashed on to a screen for, say, a tenth or a twentieth of a second.One of the exercises has required students to fix their eyes on some central point, taking in the words on either side.Such word patterns are often constructed in the shape of rather steep pyramids so the reader takes in more and more words at each successive fixation.All these exercises are very clever, but it’s one thing to improve a person’s ability to see words and quite another thing to improve his ability to read a text efficiently.Reading requires the ability to understand the relationship between words.Consequently, for these reasons, many experts have now begun to question the usefulness of eye training, especially since any approach which trains a person to read isolated words and phrases would seem unlikely to help him in reading a continuous text.
59.The time of the recognition span can be affected by the following facts EXCEPT________ .
   A.one’s familiarity with the text B.one’s purpose in reading
   C.the length of a group of words       D.lighting and tiredness
60.The author may believe that reading ______.
   A.requires a reader to take in more words at each fixation   
B.requires a reader to see words more quickly
   C.demands a deeply-participating mind                   
D.demands more mind than eyes
61.What does the author mean by saying the underlined sentence in the second paragraph?
   A.The ability to see words is not needed when an efficient reading is conducted.
   B.The reading exercises mentioned can’t help to improve both the ability to see and to
comprehend words.
  C.The reading exercises mentioned can’t help to improve an efficient reading.
  D.The reading exercises mentioned have done a great job to improve one’s ability to see
words.
62.What is the writer’s attitude in writing this passage?
   A.critical   B.neutral   C.pessimistic     D.optimistic

We are all called upon to make a speech at some point in life, but most of us don’t do a very good job. This article gives some suggestions on how to give an effective speech.
So, you have to give a speech—and you are terrified. You get nervous, you forget what you want to say, you stumble over words, you talk too long, and you bore your audience. Later you think, “Thank Goodness, it’s over. I’m just not good at public speaking. I hope I never have to do that again.”
Cheep up! It doesn’t have to be that bad. Here are some simple steps to take the pain out of speech making. Ask yourself the purpose of your speech. What is the occasion? Why are you speaking? Then, gather as many facts as you can on your subject. Spend plenty of your time doing your research. Then spend plenty of your time organizing your material so that your speech is clear and easy to follow. Use as many examples as possible, and use pictures, charts, and graphs if they help you make your points more clearly. Never forget your audience. Don’t talk over their heads, and don’t talk down to them. Treat your audience with respect. They will appreciate your thoughtfulness.
Just remember: Be prepared. Know your subject, your audience, and the occasion. Be brief. Say what you have to say and then stop. And be yourself. Let your personality come through so that you make person-to-person contact with your audience.
If you follow these simple steps, you will see that you don’t have to be afraid of public speaking. In fact, you may find the experience so enjoyable that you volunteer to make more speeches! You’re not convinced yet? Give it a try and see what happens.

A good night’s sleep in the early years of life could be very important in preventing a child becoming obese, say scientists. Babies and pre-school children who sleep for less than ten hours a night are more likely to be overweight when they are older, research has found. Experts believe that those who do not get enough sleep are more likely to feel hungry and want more calorie-rich food during the day.
Former research has linked sleeping with obesity in adults and teenagers, but this is one of the first to look at very young children. Researchers from the Universities of Washington and California looked at the sleeping habits of almost 1,000 children under the age of five. They found those who had less than ten hours’ sleep were twice as likely to be overweight five years later.
Childhood obesity has doubled over the past 10 years. A quarter of secondary school pupils are now judged to be so overweight that their health is in danger. Experts believe sleep, or lack(缺乏)of it, could be a major cause of this. On average children are sleeping for an hour less than they did 30 years ago. Last year Chinese researchers looked at more than 5,000 youngsters and found that those who were able to catch up on (補充)sleep at the weekend were far less likely to get body weight problems. Scientists have also found a link between lack of sleep and diabetes(糖尿。. Last year Canadian researchers discovered those who did not get seven or eight hours’ sleep a night were two and a half times more likely to become sick.
【小題1】The underlined word “obese” in the first paragraph may mean       .

A.quite protective B.very sad
C.very fatD.quite young
【小題2】According to Chinese researchers, if a person who lacks sleep can get more sleep during weekends,       .
A.he won’t get hungry easilyB.he will feel tired all the time
C.there will be little chance of him becoming fat
D.it will be very hard for him to fall asleep at night
【小題3】From the passage we know       .
A.too little sleep will result in illness besides obesity
B.in the past people didn’t connect sleep with weight
C.fat children must have slept less than 10 hours five years ago
D.most children are unhealthy because of little sleep
【小題4】What would be the best title of the passage?
A.A good night’s sleep helps the development of kids’ brain!
B.Ten hours’ sleep prevents overweight in kids!
C.Children are sleeping much less nowadays!
D.More teenagers get weight problems!
【小題5】Where can you most probably read this passage?
A.In the latest news.B.In a children’s book.
C.In a health magazine.D.In a scientist’s diary.
