题目内容
7.Enough sleep is important to health.The amount of sleep needed(61)depends (depend) on the age of the person and the conditions in(62)whichsleep takes place.The young may need more sleep than the old,but usually eight hours are enough for the health of grown-ups.Some can do with(63)less than this amount,but(64)othersmay need more.Every person knows his own need.(65)It is then a matter of good judgment to satisfy his need.Sleep (66)should always be enough to make one bring back his(67)strength (strong) and get ready for a day's work.Fresh air is necessary to sound sleep.So it is not without reason for some people to think that it is practicable to sleep in the open air.A bath at bedtime,(68)neither hot nor cool but of body temperature,may be(69)helpful(help) to sleep.Sleep producing drug(帮助睡眠的药物) should never be taken except when(70)suggested (suggest) by a doctor.
分析 短文主要讲了睡眠对身体健康的重要性,并给出了如何睡得好的建议.
解答 61.depends,考查谓语动词,句子描述的是一般事实,因此使用一般现在时,主语是单数,depend使用其单数形式depends.
62.which,考查定语从句,从句的引导词使用"介词+关系代词",指事物的关系代词使用which.
63.less,考查比较级,根据下一句 need more,可知这里指有些人睡更少也可以,因此使用little的比较级less.
64.others,考查代词,前面指some"一些人",此处指"其他人"使用代词others.
65.It,考查代词,指代前文提到的事情使用代词it.
66.should,考查情态动词,根据语境应使用"应该"should.
67.strength,考查名词,位于形容词性物主代词his后应使用名词strength.
68.neither,考查固定搭配,neither…nor…"既不…也不…".
69.helpful,考查形容词,位于be动词后应使用形容词helpful"有用的".
70.suggested,考查省略句,suggest与主语Sleep producing drug构成被动的关系,因此使用被动语态be done的形式,主从句主语一致,并且从句含有be动词,可以把主语和be动词一起去掉,故答案为suggested.
点评 对于语法填空这类题,一是懂得分析句子结构,二是知道充当各个句子成分的词类或词性,从语法上确定答案,当然,对于某些固定搭配也要牢记,在平时的学习中要多积累这些词汇或短语,对于句子使用的时态语态也要通过语境进行确定.
