4.As you know,reading in the sun ______ your eyes.( )A. | is harm to | B. | is harmful to | C. | does harmful to | D. | harm to |
分析 如你所知,在太阳底下读书对你的眼睛有害.
解答 答案:B
解析:分析句子结构可知,动名词短语reading in the sun"在太阳底下读书"作句子的主语;动名词短语作主语时,句子的主语当作三单.故D选项直接排除(正确的应该是:harms),C选项应该为"does harm to"(因为does是动词,所以其后接名词),A选项应该为"be harmful to"(对…有害).综上,本题答案为B选项.
点评 本题考查词语的辨析,做此类题目时一定要清楚各个选项的含义及用法;再结合句意及其它要求确定最终的答案.

We store memories in networks in our brains.Whenever we learn something new,we(44)Cnew connections between neurons(神经元),called synapses(突触).In 2003,two biologists proposed something very(45)D:during the day,we learn so much and develop so many synapses that things(46)Dget ourselves confused.

So they set up a painstaking experiment,in which an assistant scientist collected 6,920synapses from (49)A,both awake and sleeping.Then,they(50)Athe shape and size of all these synapses,learning that the synapses in sleeping mice were 18percent smaller than in awake ones.
After this,they designed a(51)Ctest for mice.They placed the animals in a room where they would get a mild electrical shock if they walked over one particular (52)Cof the floor.They injected(注射)some of them with a substance that had been proved to prevent the pruning of new synapses.The mice that experienced this were(53)Alikely to forget about the section and after a good night's sleep,they(54)Bto walk as usual,while mice that slept normally remembered better.
Then,they found that the pruning didn't strike every neuron.Some 20% were unchanged,likely well-established memories that shouldn't be tampered with(被窜改).In other words,we sleep to(55)A-but in a smart way.
