Ⅱ.阅读理解
(2009年合肥三模) It’s true that teens don’t get enough sleep，but changing the school starting time would have a chaotic_effect and throw everyone off balance.
Scientists have shown that teens are more active later at night than children and adults，so most teens are probably staying up later for whatever reasons.“The researchers measured the presence of the sleep­promoting hormone (荷尔蒙) in teenagers’ saliva (唾液) at different time of the day.They learned that the hormone levels rise later at night than they do in children and adults—and remain at a higher level later in the morning.Measuring the hormone in the saliva is a good way to show that most teens have sleep problems，but changing school schedules isn’t t he best way to fix this.Most people arguing against changing school schedules would say that it would only cause teens to stay up and wake up later，thus leaving them with the same problem.
The biggest problem schools would come across from changing their schedules would be the after school and job conflicts students and teachers would meet.“Teachers reported that students were more alert，and research showed that after­school spo rts and jobs would suffer.Students in that area might have been able to deal with less time for jobs and sports somehow，but some of them have practice and earlier plans that would become conflicted if this change were to occur.Most students rarely have time to play a sport and do homework before 9 or 10 o’cl ock.Opening schools later may have worked for some areas，but the reality is often very different.
1．The meaning of the underlined word “chaotic”in the 1st paragraph is close to________.
A．positive B．apparent
C．negative D．ambiguous
2．Most teens have sleep problems because________.
A．they are more active than children and adults
B．school work takes up most of their time
C．their hormone levels are higher later at night
D．they probably like staying up for no reason
3．Which of the following is TRUE according to the passage?
A．There are many conflicts between students and teachers.
B．Some of the teachers have practice and earlier plans.
C．Most students are able to do sport and homework before 9∶00.
D．Wa ys to solve students’ sleep problem vary from area to area.
4．The passage mainly develops by________.
A．giving reasons B．showing examples
C．comparing facts D．offering solutions
(2010年上海春招) All over the world，children in hospital are being treated with a new kind of medicine：Laughter.Lucy is 23 and works for Theodora Children’s Trust.She is one of many clown (小丑) doctors who bring a smile to the faces of sick children.
“I’m a Theodora clown doctor.I call myself Dr Looloo.I spend two days a week in children’s hospitals，making funny faces，telling jokes，and doing magic tricks.As I walk into the wards I blow bubbles，shake hands with the kids，and make up nonsense songs for those children well enough to sing.I take special balloons to make ‘balloon animals’ and tell funny stories about them.
I’m naturally a very cheerful person.I’ve always been a clown.In fact my father’s a clown and I started working with him when I was eight years old.I knew it was just the job for me and I became a clown doctor because I think it’s a great way to cheer up sick，frightened children in hospital.
Being a clown in hospital is very tiring both physically and emotionally.We have to learn not to show our feelings，otherwise we’d be useless.Clown doctors are sensitive but this is not a side most people see.To the children we’re happy all the time.I’m still learning to allow myself to feel sad occasionally.There working with a very sick little girl from Bosnia who speaks no English，so our only common language is laughter.
At weekends I participate in events to raise money for Theodora Children’s Trust.It’s a c harity，so we are paid with the money people give.Being a clown doctor makes the worrie s of everyday life seem small.All in all I feel honoured to do this job.”

to be obeyed是不定式的被动式作主语补足语。

句意为：对于十几岁的青少年来说，总有太多的规则需要他们去遵守。

2．A 考查情态动词的被动语态。

根据前一分句中No...is allowed...可知要用must (必须)，带有强制意味。

句意为：十二岁以下的儿童必须在家长的陪同下方可靠近湖边。

3．C 考查非谓语动词。

to be left alone是不定式的被动式作宾语。

leave...alone 让……独自呆着。

in explanation of对……作出解释。

5．A 考查时态和be to do sth.。

to the satisfaction of sb.使某人满意的是。

7．B 考查代词。

it和one都可以代替前文提到的单数可数名词，但it代替特定之物，one泛指同类中的某一个。

8．B 考查动词不定式。

to try to persuade him to stay是不定式短语作目的状语。

we could后省略了动词原形do。

9．A 考查动词词组的辨析。

embarrassed尴尬的，困窘的，符合题意。

11．C 本题中过去分词短语accompanied by heavy rain作定语修饰winds，accompany 意为“伴随、陪伴”，符合语境。

12．C 本题主要考查it作形式宾语的句型。

动词love，like，hate，dislike，enjoy，prefer，appreciate等词后一般不能直接跟句子，而应在句子前面加it，然后再接when 或if所引导的句子。

再如：I hate it when people speak with their mouths full.
13．C 句意为“尽管很忙，父母每周也应该拿出至少两个小时的时间与孩子们在一起”。
