To keep us healthy, it is necessary ________ take some exercise for some time every day.


  1. A.
    for we to
  2. B.
    to for we
  3. C.
    for us
  4. D.
    for us to
D
這個(gè)句子比較復(fù)雜。句子前面的動(dòng)詞不定式作目的狀語(yǔ)，it作句子的形式主語(yǔ)，因此在形容詞necessary之后應(yīng)該使用動(dòng)詞不定式作真正的主語(yǔ)。從選項(xiàng)可以看得出來(lái)，這里作主語(yǔ)的不定式是個(gè)復(fù)合不定式結(jié)構(gòu)。動(dòng)詞不定式的復(fù)合結(jié)構(gòu)應(yīng)該是“for sb. to do sth.”，因sb.在句子中作介詞for的賓語(yǔ)，故應(yīng)該使用名詞或代詞賓格，故正確答案為D。

科目：初中英語(yǔ) 來(lái)源：2012屆度江西省鷹潭市新目標(biāo)八年級(jí)下學(xué)期期末教學(xué)質(zhì)量檢測(cè)英語(yǔ)卷 題型：閱讀理解

Some people like to get up late, but some do not. In fact, it is really good for us to get up early every day. Maybe those who don't like getting up early will not believe this, but it is true.

Scientists made a survey in about one thousand people, and then they found that early rising people had less disease than late rising people, and early rising people also looked healthier than late rising people, and so on.

So we may know early rising is helpful in more than one way. First, it helps to keep us healthy. We all need fresh air. But air is never as fresh as early in the morning. Besides, it is useful to do morning exercises.

Secondly, early rising helps us in our studies. In the morning we learn more quickly and find it easier to understand what we learn.

Thirdly, early rising can give us a plan of our work for the day. We cannot work well without a good plan.

Fourthly, early rising gives us enough time to get ready for our work^ such as to wash our hands and faces and eat our breakfast.

Late risers may find it difficult to form the habit of early rising. They have to make an effort (努力）to do so. As the English proverb says, “Early to bed and early to rise makes a man healthy, wealthy and wise•”

Judge the following sentences true (T) or false (F) according to the passage.

1.People don't always agree on whether to e»et up early.

2. In the passage the writer gives four reasons for early rising.

3. Early rising makes people happier according to the passage.

4.Early risers don't look as healthy as late risers.

5.The writer encourages people not to sleep late.
