What is a cause for the change of Stefania’s body clock?A．Eating fewer hours of sleep.B．Having more hours of sleepC．Lacking physical exercise.D．Getting no natural light.

第1题：

DOn May 23,1989, Stefania Follini came out from a cave at Carlsbad, New Mexico. She hadn’t seen the sun for eighteen and a half weeks. Stefania was in a research program, and the scientists in the program were studying body rhythms(节奏). In this experiment Stefania had spent 130 days in a cave, 30 feet in depth.

During her time in the cave, Stefania had been completely alone except for two white mice. Her living place had been very comfortable, but there had been nothing to tell her the time. She’d had no clocks or watches, no television or radio. There had been no natural light and the temperature had always been kept at 21℃.

The results were very interesting. Stefania had been in the cave for over four months, but she thought she had been there for only two. Her body clock had changed. She hadn’t kept to a 24-hour day, she had stayed awake for 20-25 hours and then had slept for 10 hours. She had eaten fewer meals and had lost 171bs in weight as a results! She had also become rather depressed（抑郁）.

How had she spent her time in the cave? As part of the experiment she’d done some physical and mental tests. She’d recorded her daily activities and the results of the tests on a computer. This computer had been specially programmed for the project. Whenever she was free, she’d played cards, read books and listened to music. She’d also learned French from tapes.

The experiment showed that our body clocks are affected by light and temperature. For example, the pattern of day and night makes us wake up and go to sleep. However, people are affected in different ways. Some people wake up naturally at 5:00 am, but others don’t start to wake up till 9:00 or 10:00 am. This affects the whole daily rhythm. As a result, the early risers, on the other hand, are tired during the day and only come to life in the afternoon or evening!

第68题：

Stefania stayed in the cave for a long time because ______.

A. she was asked to do research on mice

B. she wanted to experience loneliness

C. she was the subject of a study

D. she needed to record her life

63._________
A: how
B: why
C: where
D: what

答案：A

解析：

从后半句when to form flowers and when flowers should open知道，只有plants才有花。前面没有定冠词修饰的plants是泛指植物这一大类，与动物类相对应。

后面出现的when to leave the protective cocoons and fly away提示我们，唯有选in-sects才是正确的，因为只有insects才有protective cocoons，而birds、 fish和snakes都没有。

affect作为动词是“影响”的意思，而effect作为动词则是“使发生，使生效”的意思。这里谈论的是动植物生物钟的一般情况，所以使用动词的一般现在时。

这里应使用介词短语，因为其后是名词。because和since都有“因为”的意思，但它们都是连词，用来引导原因状语从句，for the reason that后接句子，所以也不是答案。

根据下句中的in the longer hours of daylight in summer和上句中的the number of hours of daylight，以及该段的中心思想，可以判断，应选择B，因为冬天日短夜长，夏天则反之。

本句中有birds , migration这些词，下一句又谈及迁徒飞行前的躁动不安，就知道应该填词义为“飞行”的名词。fly是动词，不能选择；其他两个选项也都不合适。flight是 fly的名词形式，所以是合适的选择。

该句句子的主干是：主语birds，谓语become restless。所以，所填的词是过去分词，修饰birds。从上下文表达的意思判断，ordered by（被命令）、he1ped by（被帮助）和in- truded on（被强加）都不匹配，只有prevented from是合适的选择。

很明显，这里需使用连词，连接该句中平行的两个分句。而根据整个句子的句意，上半句和下半句形成反差对比：become restless when the time of the flight has ended，所以应选择 but，表示相反的两层意思。

portion是“一定数量，一份”, section是“切下的部分”, kind是“种类”，都不符合上下文意思连贯的要求。唯有B是正确的选项。

不能选择C，因为主语是group，而不是cells，所以要采用动词的第三人称单数形式 seems 。 A和B不符合常识。

These一词说明，其后名词是上文已经提到的某些事物，即cells。从下文中可以看出，尽管actions一词也在上文中出现，但该词不符合句意。选项A和B意思不准确。

该句中的三个宾语都是带疑问副词的动词不定式，所以都要用动词原形。awaken 是唯一合适的选择，woke是wake的一般过去形式，awakening是形容词，wake-up是名词。

studying后面是一个从句作它的宾语，而从句起首处应有个连词。把C或D填入空格，上下文意思不连贯。根据下文的例子，作者讨论的不是生物钟为什么会影响我们的工作，而是生物钟如何影响我们的工作。所以，how是正确的选择。

从句子结构中不难看出，to accept the major change in work hours是实际上的主语，而此处需要一个形式主语，所以只能选择It。

该句中的understanding既然是上句中提到的better understanding , C便是最佳的选项。其他三个选项均不符合语法。

第5题：

The park is to a city__________the lung is to man′s body.

A.as
B.that
C.which
D.what

答案：D

解析：

考情点拨：本题考查表语从句。应试指导：句意：公园对于城市就像肺对于人体一样。what引导表语从句，在从句中作表语一本句用的是一个固定结构：A is to B what C is to D，意思是“A对于B就像C对于D一样”。

A、There is no automatic method to change the PM(s) status to INACTIVE
B、The PM(s) will become in INACTIVE if 'Change the Status of All Associated PM(s) to Inactive?' is checked while decommissioning the asset
C、The only way to change the status of the PM(s) to INACTIVE is to remove the assets from the PM(s) and then change the status of the PM(s) to INACTIVE
D、If the 'Change the Status of All Associated PM(s) to Inactive?' is not selected during decommissioning, the PM(s) status will remain ACTIVE; however, work order cannot be generated from the PM having a decommissioned asset

第16题：

The willful blindness in hockey toward concussions (头部撞击) has dropped. Hockey Canada has followed the lead of USA Hockey in preventing body checking (身体拦截) below age 13.
(41) __________ This country's children have been facing similar danger at early ages, and Hockey had to deal with a deep worry in the winds of Canadians to make the rule change. The liking for body checking from an early age is part of what makes Canadian hockey what it is.
The change in rules should be taken as a chance to draw special attention to skill development in an environment free of danger. (42)__________
For years, many Canadian hockey parents and coaches have insisted that body checking at early ages is necessary to ensure that players can do it safely at older ages. (43)__________ When USA Hockey changed its rules for the 2011-2012 season, it also created bodychecking-education programs that will be mandatory (强制的) for all coaches, including those teaching players in the pre-checking ages. And it began to encourage more"touch", without real body checking from 9 to12. It also made the rules for 13 and up stricter. (44) __________Hockey Canada has taken serious steps to do away with hits on the head. (45) __________Too often, body checking has been used to try to separate a player from his head rather than from the ball. Children were paying a price for this country's love of the game.
There are always changes in Canada's game, and the change in the body checking age sends the clearest message yet to coaches and parents that player safety is paramount (至上的) in the game.

A.True or not, there may be a safer way to teach hitting than to make younger players pay a price for it in head injuries.
B.However, it's hard to change a sports culture so connected with who we are as a country.
C.A bad head injury of Sidney Crosby, the hockey's greatest star, opened the eyes of hockey people everywhere.
D.It may also control the loss of thousands of young players who don’t enjoy that environment.
E.The USA is trying to show that it's possible to teach hockey protective skills without putting 11 and 12-year-olds in greater danger. It's worth the try.

答案：B

解析：

本段最后一句“Children were paying a price for this country’s love of the game．”意思是“由于整个国家对曲棍球运动的热爱，孩子们因而要付出代价”。这与一个国家的体育文化有紧密关系，因此正确答案是B．

第17题：

In an ACL cause， what’s the function of log or log-input keyword at the end？
