11."The chair is out to kill us,"says James Levine,a professor at the Mayo School of Medicine.Most of us have years of sitting experiences,considering ourselves quite good at it.(36)BBut unfortunately,a good deal of data suggests that we're off our chairs to spend so much time on the vast variety of other seats where we're fond of parking our bottoms.Here are some things that scientists have learned about the insidious(潜伏的)nature of sitting.
Sitting position has gone wrong.
The human body is designed for walking.(37)EBut lately,not so much.In general,scientists believe,Americans now sit for more than half of their walking hours.Sadly,the sitting position exerts force on the body which can lead to a lot of trouble including poor circulation(血液循环),aches and pains.
(38)A
We're not using much energy when we're sitting still.(39)G It is also just another way of saying"watch out for extra pounds."It is mainly the chair that has caused the increase in obesity rates.A person with a desk job may burn 300 calories a day at work,but the same person might burn 2,300calories a day in jobs that require considerable physical efforts.In other words,we need more walking to burn more calories.
Realize the damage.
Sitting at your desk and working hard for hours on end can increase your chances of getting a promotion.(40)DWhen comparing people who spent the most time sitting with those who spent the least time sitting,researchers found more sitting increases the risks of death from all causes.

A.Make people become too fat.
B.We will say nature intends us to do it.
C.They ought to work out to build their bodies.
D.But it also brings people diseases or even early death.
E.Certainly people have done that for thousands of years.
F.We should be more patient and work longer than before.
G.That is just another way of saying"we are not burning many calories".

分析 文章介绍了久坐不利于健康,会给人们带来伤害.1、久坐不利于血液循环,给人体造成损伤;2、长时间坐着,身体不会消耗很多能量,使人们变得更胖;3、久坐给人们带来疾病和早死,增加死亡的风险.

解答 36-40 BEAGD
36.B联系下文题.根据下文Here are some things that scientists have learned about the insidious (阴险的)nature of sitting.可知科学家们已经了解这样天性的坐姿是很危险的.B项:We will say nature intends us to do it.我们会说天性让我们这样做的,符合文意.故选B.
37.E上下文串联.根据上文The human body is designed for walking.可知人体是为行走而设计的;根据下文But lately,not so much.可知但是最近几年里,坐的时间要比步行时间长.E项:Certainly people have done that for thousands of years.当然了,人们已经这样做有上千年了,符合文意.故选E.
38.A小标题选择.根据下文We're not using much energy when we're sitting still.及本段内容可知,当我们坐着不走动时,身体就不会消耗能量.这样会导致肥胖率上升.A项:Make people become too fat.让人们变得更胖,符合文意.故选A.
39.G联系下文题.根据下文It is also just another way of saying"watch out for extra pounds.可知它也是"小心赘肉"的另一种说法.G项:That is just another way of saying"we are not burning many calories".这是另外一种方式说"我们不能消耗很多的能量,符合文意.故选G.
40.D语境辨析题.根据下文When comparing people who spent the most time sitting with those who spent the least time sitting,researchers found more sitting increases the risks of death from all causes.可知研究人员发现把长时间坐着的人与短时间坐着的人相比较,长时间坐着会增加死亡的风险.D项:But it also brings people diseases or even early death.这会给人们带来疾病和早死,符合文意.故选D.

点评 答题前一定要略读全文,把握文章要表达的主题,注意前后句与句,段落与段落之间的关系.答题中,一定要认真分析,注意选项与上下文的关系,与前后单词的关系.对于一时没有太大的把握的题可以放到最后再来完成,因为有时答案可以从下文内容体现出来.答完后再通读一遍文章,看看所选选项能不能是语句通顺,语意连贯.

(54)B  in some schools there is no extra support to help young language learners acquire the language of instruction,in most countries where there are large numbers of young learners,there is a (55)C awareness of their special needs.There is (56)D a need to identify the needs of young language learners,to (57)B what level,if any,of proficiency they have in the target language to diagnose their strengths and areas in need of improvement.Language (58)C,whether this is informal,classroom-based,or large-scale,thus has a (59)D role to play in gathering the information needed for these purposes.
Unfortunately,the vast majority of teachers who work with young language learners have had little or no (60)C training or education in language assessment.Teachers are involved in assessment on a daily basis,as they (61)A their pupils'classroom performance,and as they develop formal classroom assessments.Assessment should therefore,wherever possible,be familiar and involve familiar adults,rather than (62)C.The environment should be safe for the learner.Teachers responding(63)B to the child's efforts is ideal for young learners.Such feedback maintains attention and (64)D.As children grow,they are able to work more (65)A and for long spans of time without ongoing feedback.
