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(潛伏的)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(血液循環(huán)),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 文章介紹了久坐不利于健康,會給人們帶來傷害.1、久坐不利于血液循環(huán),給人體造成損傷;2、長時間坐著,身體不會消耗很多能量,使人們變得更胖;3、久坐給人們帶來疾病和早死,增加死亡的風險.

解答 36-40 BEAGD
36.B聯(lián)系下文題.根據(jù)下文Here are some things that scientists have learned about the insidious (陰險的)nature of sitting.可知科學家們已經(jīng)了解這樣天性的坐姿是很危險的.B項:We will say nature intends us to do it.我們會說天性讓我們這樣做的,符合文意.故選B.
37.E上下文串聯(lián).根據(jù)上文The human body is designed for walking.可知人體是為行走而設計的;根據(jù)下文But lately,not so much.可知但是最近幾年里,坐的時間要比步行時間長.E項:Certainly people have done that for thousands of years.當然了,人們已經(jīng)這樣做有上千年了,符合文意.故選E.
38.A小標題選擇.根據(jù)下文We're not using much energy when we're sitting still.及本段內容可知,當我們坐著不走動時,身體就不會消耗能量.這樣會導致肥胖率上升.A項:Make people become too fat.讓人們變得更胖,符合文意.故選A.
39.G聯(lián)系下文題.根據(jù)下文It is also just another way of saying"watch out for extra pounds.可知它也是"小心贅肉"的另一種說法.G項:That is just another way of saying"we are not burning many calories".這是另外一種方式說"我們不能消耗很多的能量,符合文意.故選G.
40.D語境辨析題.根據(jù)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.可知研究人員發(fā)現(xiàn)把長時間坐著的人與短時間坐著的人相比較,長時間坐著會增加死亡的風險.D項:But it also brings people diseases or even early death.這會給人們帶來疾病和早死,符合文意.故選D.

點評 答題前一定要略讀全文,把握文章要表達的主題,注意前后句與句,段落與段落之間的關系.答題中,一定要認真分析,注意選項與上下文的關系,與前后單詞的關系.對于一時沒有太大的把握的題可以放到最后再來完成,因為有時答案可以從下文內容體現(xiàn)出來.答完后再通讀一遍文章,看看所選選項能不能是語句通順,語意連貫.

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.
