The suggestion they all objected to         to be effective finally.

A．provingB．proveC．had provedD．proved

D

解析試題分析：句意：他們都反對的那個建議最后證明是有效的。這里they all objected to是定語從句，先行詞是suggestion，關(guān)系詞是作賓語，給省略掉了；這里缺少的是謂語動詞，故排除A；根據(jù)objected用的是過去式，可知答案應是D。
考點：考查動詞時態(tài)的用法。
點評：本題難度適中。動詞時態(tài)的考查與一定的語境結(jié)合一起增加了試題的難度，有的考生時態(tài)的用法背的很熟，但在不同的語境下，就做不對了，提醒考生一定要會分析理解語境。
即學即練: Planing so far ahead      no sense—so many things will have changed by next year.
A.made        B.is making    C.makes        D.has made
解析：C。句意：“計劃這么超前毫無意義—到明年許多事情會發(fā)生變化的。”前句表示現(xiàn)在的情況make no sense，后句表示到將來會產(chǎn)生的后果will have changed。一般現(xiàn)在時表示主語的特征或狀態(tài)。is making和has made表示具體的動作過程，故不選。因此選C。

閱讀下面的短文，請根據(jù)短文后的要求答題。（請注意問題后的字數(shù)要求）
     [1] Doctors may soon have some suggestions for health that even kids will like: more playtime. European
and international health experts say a new study makes the most convincing case for the benefits of children
being active. They say the research may lead to new guidelines saying youngsters aged between 5 and 16 need
to be active up to 1.5 hours a day.
     [2] Experts said the study doesn't mean children need to be on treadmills (跑步機) or in a soccer
leagues-they just need to be able to run around and play physically, even for short bursts of time.
     [3] The study looked at 1,732 9-year-olds and 15-year-olds from Denmark, Estonia and Portugal. Physical
activity was observed for four continuous days. Despite differences among the three coun- tries where children were observed, the benefits of physical activity were the same.
     [4] About 40 percent of those observed were reasonably ac- tive, while the rest were sedentary, researchers said. The study found that the benefits of physical activity applied to all children- not just to obese ( 肥胖的)
children normally thought to be at a higher risk.
     [5] While much attention has been paid to children's bad eat- ing habits,this study calls for equal weight to
be placed on activity levels.
     [6] "We don't need to be getting kids running on treadmills in the gym." said Cavil."We need to encourage
kids to play." One of the study's key findings, he explained, is that it proves the benefit of short bursts of activity, rather than a need for continuous exercises.
     [7] But _____ perhaps the greatest factor in children's physical activ- ity will be the parents themselves."It's
not just that children should be more active,it's the whole family," said Weiss."Parents should be role models."

The population of the earth goes on increasing at its present rate and there will eventually not be enough resources left to sustain life on the planet. By the middle of the 21st century, if present trends continue, we will have used up all the oil that drives our cars, for example. Even if scientists develop new ways of feeding the human race, the crowded conditions on earth will make it necessary for us to look for open space somewhere else. But none of the other planets in our solar system are capable of supporting life at present. One possible solution to the problem, however, has recently been suggested by an American scientist, Professor Carl Sagan.

Sagan believes that before the earth’s resources are completely exhausted it will be possible to change the atmosphere of Venus（火星）and to create a new world almost as large as earth itself. The difficulty is that Venus is much hotter than the earth and there is only a tiny amount of water there.

Sagan sugges that algae（藻類）organisms, which can live in extremely hot or cold atmospheres and at the same time produce oxygen, should be developed in conditions similar to those on Venus. As soon as this has been done, the algae will be placed in small rockets.     Spaceships will then fly to Venus and fire the rockets into the atmosphere. In a fairly short time, the algae will break down the carbon dioxide into oxygen and carbon.

When the algae have done their work, the atmosphere will become cooler, but before man can set foot on Venus it will be necessary for the oxygen to produce rain. The surface of the planet will still be too hot for men to land on it but the rain will eventually fall and in a few years something like earth will be reproduced on Venus.

1．In the long run, the most difficult problem caused by population growth on earth will probably be the lack of         .

       A．food                   B．oil                       C．space                  D．resources

2．Carl Sagan believes that people might live on Venus because         .

       A．it might be possible to change its atmosphere

       B．its atmosphere is the same as the earth’s

       C．there is a good supply of water on Venus

       D．the days on Venus are long enough

3．Algae can be developed on Venus because they are able to         .

       A．live in very hot temperatures                 B．live in very cold temperatures

       C．produce oxygen                                   D．a(chǎn)ll of the above

4．According to the writer, the most key condition for man to land on Venus eventually is that         .

       A．the algae have done their work              B．the atmosphere becomes cooler

       C．there is enough oxygen                         D．it rains there
