61._________
A:work
B:task
C:job
D:place

答案:C
解析:
从句子的意思看,这里应该有“需要”的意思,所以应该在C和D之间选择。need可以 。作情态动词用,也可以作实义动词用,前面既然用了will,那说明这里应该跟作实义动词用的need,故选D。
这里what引导的从句意思是:在工作时你可能面临什么不利健康的因素。at work是固定搭配,意思是“在工作”。
这句用how引导的从句意思是:你每日的饮食和推荐的标准相比之下如何。最合适的搭配是daily diet。
spend … doing…意思是“花费……做某事”,符合句意。devote后面要跟介词to,意思是“专心于,致力于”,故选C。
engage in是一个动词短语,意思是“从事……活动”。
这里空格里要求填人的是引导该宾语从句的连接词,表达“是否……”的意思,只有whether or not符合句意。
本句句意要表示的是目的,即“为了要……,你应该进行一次体检,以确定你的血液、心脏、肺功能是否正常。”表示目的要用不定式,A和D的区别是A是主动语态,D是被动语态,这里要用主动语态,故选A。
serve as是固定搭配,意思是“作为……,起……的作用”。
四个选项都是连接词,可以连接两个从句。作为连接词,Once表示“一旦”,符合句意。Unless除非,如果不;If如果,即使,是否,假如;Although虽然,尽管,故选B。
to be based on是个固定的表达方式,意思是“在……的基础上,以……为依据”。
work在表示“工作”的意思时是不可数的,前面有不定冠词a,所以被排除了。have a job是“有工作”的意思,符合句意,同时也与下文“reducing the stress of your job”对应。
to be followed by是“后面跟着……”的意思,符合句意。
give some thought to是固定搭配,意思是“考虑……”,符合句意。
be in good/poor health是短语,意思是“身体好/身体不好”,符合句意。
benefit是及物动词,意思是“使……获益”,符合句意。reap收获;harvest收获,一般作名词用;lead领导,引导。

_________(64)
A:for
B:in
C:with
D:on

答案:B
解析:
从句子的意思看,这里应该有“需要知道”的意思,所以选择应该在C和D 之间,need可以作情态动词用,也可以作普通动词用,此处空白前面用了will,那说明这里应该跟作普通动词用的need,所以选项D是正确的。本句的意思是“要绘制健康图谱,就需要知道你的家族带有何种疾病”。
本句意思是“在工作时你可能面临什么不利健康的因素”,短语“在工作时”的英语是at work,其他介词都不合适,因此选项D是正确的。
这句话的意思是“你每日的饮食和推荐的标准相比之下如何”,‘旧常饮食”最合适的说法是daily diet。选项A最合适。
空白处前面是主语you,后面是exercising , -ing形式提示这里只能用 spend,如果要用devote,应该是短语devote to。要表示花多少时间,use和take都不合适。本句的意思是“每周锻炼几次身体以及从事何种运动。”
engage in是固定搭配短语,意思是“从事······活动”。
作为you will need to know后面一系列宾语从句中的最后一个,这个空格里需要填入的是引导该宾语从句的连接词,表示的是“是否······”这个意思,只有选项B最合适。本句的意思是“你是否有上瘾的东西”。
句首的短语要表示的是目的,本句的意思是“你应该进行一次体检,以确定你的血液、心脏、肺功能是否正常”。这里要用主动态,因此选择A项。
serve as是个短语,意思是“作为······起······的作用”。本句的意思是“这次检查将被用作基线”。
这里需要连接词,四个选项都具有这个功能,once的意思是“一旦”,最合适。本句的意思是“一旦图谱被完整地画出来,你可以开始基于特定的图谱确定优先需要考虑的健康问题”。
be based on是个固定短语,意思是“在······的基础上”,选项D最合适。
本句意思是“有一个压力大的工作”。work当工作讲时是不可数的,所以被排除了。余下的三个选项中只有C项job是工作的意思。
to be followed by是固定搭配“后面跟着······”的意思,其他几个介词都不对。本句的意思是“接下来是减重”。
give some thought to是一个习惯的表达方式,意思是“考虑······”。本句的意思是“如果你不想得癌症和心脏病的话,就好好考虑一下不要再喝马丁尼了”。
be in excellent health是短语,意为“身体很好”。本句意思是“就算是对从来没生过一天病的年轻的上班族来说,尽管健康状况很好,但是好好检查一下卫生习惯、生活与工作环境会带来些改变,这会在将来令他受益匪浅”。
benefit是及物动词,意为“使······得益”;reap是“收获”的意思;harvest一般作名词用;lead是“领导”的意思。只有C项最合适。

此处表示是目的,即“为了把一切描述清楚,你应该进行一次体检,以确定你 的血液、心脏、肺功能是否正常”。表示目的要用不定式,A和D的区别是A是主动语态,D是被动语态,这里要用主动语态。所以答案为A。

这里需要的是一个连接两个从句的连接词,四个选项都具有这个功能,但意义各不相同,B项once的意思是“一旦”,符合本句的意思。

There is no creature that does not need sleep or complete rest every day.
If you want to know why,just try going without sleep for a long period of time.You will discover that your mind and body would become too tired to work properly.You would become irritable and find it hard to think clearly or concentrate on your work.So sleep is quite simply the time when the ceils of?your body recover from the work of the day and build up supplies of energy for the next period of activity.
One of the things we all know about sleep is that we are Unconscious in sleep,We do not know what is going on around us.But that do.esn′t mean the body stops all activity.The important organs continue to work during sleep,but most of the body functions are slowed down.
For example,our breathing becomes slower and deeper.The heart beats more slowly,and the blood pressure is lower.Our arms and legs become limp(柔软的)and muscles are at rest.It would be impossible for our body to relax to such an extent if we were awake.So sleep does for us what the?most quiet rest can not do.
Your body temperature becomes lower when you are asleep,which is the reason people go to sleep under some kind of covers.And even though you are unconscious,many of your reflexes(反射动作)still work.For instance,if someone tickles(使觉得痒)your foot,you will put it away in your sleep,or even brush a fly from your forehead.You do these things without knowing it.

When you are sleeping,

A.all of you reflexes stop working
B.most of your reflexes stop working
C.many of your reflexes still work
D.all of your reflexes still work

答案:C
解析:
【考情点拨】推理判断题。【应试指导】文章第三段最后一句的意思是,睡眠中,身体的重要器官继续工作,但是身体大部分的功能放慢了,且从最后一段“…many of your?reflexes still work”一句我们得出,答案为C。

In the clause"...that we are unconscious in sleep"(Pam.3),the word"unconscious"means__________.

A.untiring
B.unmoved
C.quiet
D.not knowing what is happening around

答案:D
解析:
【考情点拨】词语理解题。【应试指导】本句出现于文章的第三段第一句,接下来的一句是对unconscious一词的进一步解释,即not knowing what is going on around US。
