3．We are at your service．Don't hesitateto turn （turn） to us if you have any further problems．

分析 我們隨時(shí)為你效勞．如果你有任何進(jìn)一步的問(wèn)題，不要猶豫向我們求助．

解答 答案是to turn．本題考查動(dòng)詞不定式做賓語(yǔ)；題干中hesitate（猶豫）后面往往接動(dòng)詞不定式做賓語(yǔ)，即hesitate to do 猶豫做…；故答案是to turn．

點(diǎn)評(píng) 本題是要求用所給動(dòng)詞的適當(dāng)形式填空，解題時(shí)首先考慮句中需要的是謂語(yǔ)動(dòng)詞還是非謂語(yǔ)動(dòng)詞；其次，如果是謂語(yǔ)動(dòng)詞關(guān)注時(shí)態(tài)、語(yǔ)態(tài)和數(shù)的變化；如果是非謂語(yǔ)動(dòng)詞要聯(lián)系非謂語(yǔ)的基本用法判斷非謂語(yǔ)的形式．

13．For better eyesight，doctors advise limiting the hours of screen time and encourage having enough eye resting time．
However，another study shows that sitting in front of computer or TV screens for long hours is not the only reason for myopia （近視）．An Australian research team studied young children in Sydney and Singapore to find the reasons for myopia．
The research team found that the prevalence （流行） of myopia among children in Sydney was lower than children in Singapore，even though they spent more time in front of computer and TV screens．The major finding is that children in Sydney spend longer hours on outdoor activities than those in Singapore．
Indoor and outdoor sports activities both make the eyes focus on more distant objects，which prevents the eyes from changing shape．But outdoor activities may better help avoid myopia than indoor sports activities．
Jane Gwiazda，who does research in sight problems，says："Natural light is good for eye growth．And extra vitamin D from the sun might contribute to eye growth．"
Many doctors suggest that every child gets its first eye test done when he/she is about two and half years old，and even if his/her sight seems perfect．
It is necessary for myopic children to wear glasses to prevent headaches，trouble reading or injuries．It is also important that schools invite doctors to test their students'eyes．
If that is not possible，school teachers should at least encourage parents and children to have regular eye examinations and wear glasses．And parents should remember not only to limit the total screen time for their children，but also to encourage them to spend time outdoors．
32．What's the aim of the study by the Australian research team？B
A．To find the ways to treat myopia．
B．To find the reasons for myopia．
C．To prove the bad effects of myopia．
D．To prove the prevalence of myopia．
33．Why are there fewer children with myopia in Sydney than in Singapore？C
A．Because Sydney children watch less TV．
B．Because Sydney children have more eye resting time．
C．Because Sydney children do more outdoor sports．
D．Because Sydney children use computers less．
34．What conclusion can we draw from the passage？D
A．Sydney children don't study hard．
B．Singapore children do few exercises．
C．Room light does harm to children's eyes．
D．Outdoor activities do more good to eyes．
35．Which of the following statements is TRUE？D
A．Children should have eye tests as soon as they reach school age．
B．Doing outdoor activities with no glasses is good for myopia children．
C．Children should limit their time in the sun in order to protect their eyes．
D．Focusing on distant objects can help the eyes keep their original shape．

14．Peanuts to This
Proudly reading my words，I glanced around the room，only to find my classmates bearing big smiles on their faces and tears in their eyes．Confused，I glanced toward my stone-faced teacher．Having no choice，I slowly raised the report I had slaved over，hoping to hide myself．"What could be causing everyone to act this way？"
Quickly，I flashed back to the day Miss Lancelot gave me the task．This was the first real talk I received in my new school．It seemed simple go on the Internet and find information about a man named George Washington．Since my idea of history came from an ancient teacher in my home country，I had never heard of that name before．As I searched the name of this fellow，it became evident that there were two people bearing the same name who looked completely different!One invented hundreds of uses for peanuts，while the other led some sort of army across America．I stared at the screen，wondering which one my teacher meant．I called my grandfather for a golden piece of advice； flip （擲） a coin．Heads-the commander，and tails-the peanuts guy．Ah!Tails，my report would be about the great man who invented peanut butter，George Washington Carver．
Weeks later，standing before this unfriendly mass，I was totally lost．Oh well，I lowered the paper and sat down at my desk， burning to find out what I had done wrong．As a classmate began his report，it all became clear，"My report is on George Washington，the man who started the American Revolution．"The whole world became quite!How could I know that she meant that George Washington？
Obviously，my grade was awful．Heartbroken but fearless，I decided to turn this around．I talked to Miss Lancelot，but she insisted No re-dos； no new grade．I felt that the punishment was not justified，and I believed I deserved a second chance．Consequently，I threw myself heartily into my work for the rest of the school year．Ten months later，that chance unfolded as I found myself sitting in the headmaster's office with my grandfather，now having an entirely different conversation．I smiled and flashed back to the embarrassing moment at the beginning of the year as the headmaster informed me of my option to skip the sixth grade．Justice is sweet!
53．Why was the author confused about the task？A
A．He was unfamiliar with American history．
B．He followed the advice and flipped a coin．
C．He forgot his teacher's instruction．
D．He was new at the school．
54．The underlined word"burning"in Para.3probably meansD．
A．a(chǎn)ngry      B．Ashamed       C．ready      D．eager
55．In the end，the author turned things aroundB．
A．by redoing his task              
B．through his own efforts
C．with the help of his grandfather
D．under the guidance of his headmaster．

11．It is natural that young people are often uncomfortable when they are with their parents．They say that their parents don't understand them．They often think that their parents are out of touch with modern ways； that they are too serious or too strict with their children； and that they seldom give their children a free hand．
Actually parents also find it difficult to win their children's trust and they tend to forget what they were like when young．
For example，young people like to act without much thinking．It is one of their ways to show that they have grown up and they can face any difficult situation，while older people worry more easily．Most of them plan things ahead，at least in the back of their minds，and do not like their plans to be upset by something unpleasant．When you want your parents to let you do something，you will have better success if you ask before you really start doing it．
Young people often make their parents angry with their choices in clothes，in entertainment （娛樂(lè)） and in music．But they do not mean to cause any trouble； it is just that they feel cut off from the older people's world，into which they have not yet been accepted．It is natural enough that you want to live a life in your own way，after being a child for so many years，when you were completely under your parents'control．
However，you should know that if you plan to control your life，you'd better win your parents over and try to get them to understand you．If your parents see that you have a high sense of responsibility，they will certainly give you the right to do what you want to do．
