18.Over the past decade,more than 60 percent of primary and secondary school students in China have failed to regularly get enough sleep,with excessive (過(guò)多)homework and supplementary after-school classes getting in the way of their health,a recent report suggested.
According to the report,released by China Youth and Children Research Center (CYCRC)on Oct.20,there are around 100 million young people short of sleep currently living in China.Too much homework assignments,more hours spent studying at school and increasing pressure to participate in supplementary after-school sessions are the main causes of sleep deprivation among Chinese students.
   Despite efforts by the Chinese government to ease academic burden on students,primary and secondary school students are still overwhelmed by study stress.On average,primary school students in China spend 8.1 hours at school per day,which is more than the government-approved six hours.Middle school students spend an average of 11 hours per day at school,which is three hours more than the national standard.
"The evaluation standards for teachers mainly focus on students'academic Performance and enrollment rate,so we have no choice but to deprive the students of their spare time,"a teacher from No.33 Middle School in Baotou,Inner Mongolia told the Xinhua News Agency during an interview.
"More and more after-school sessions are also imposed on Chinese students.Chinese students have to spend more time on their homework and off-campus studies,"added SunHongyan,director of CYCRC.
"Primary and secondary school students are in a crucial period of physical development,and they should sleep around nine to ten hours per day.Sleep deprivation can lead to weakened immunity and memory,and can also hold back physical growth,"said Wang Zan,a member of the China Sleep Research Society.

58.Which is not the main causes of sleep deprivation among Chinese students?B
A.too much homework assignments 
B.their parents'high expectations
C.more hours spent studying at school 
D.participating in supplementary after-school sessions because of increasing pressure

B.The Chinese government has made efforts to ease academic burden on students.
C.Only students'academic Performance and enrollment rate can evaluate their teachers.

8.I left the hospital the day after Christmas.With a headache,I could hear my mother whispering to her friends on the telephone,"What if she's disabled and not able to take care of the boys?"
Disabled?That was a possibility I'd never considered.Overweight and tired at forty-six,I was the single mother of teenaged twin sons.They took most of my time and energy.My career took the rest.
Additional tests the next day proved the symptoms were from too much stress.Though I only had problems with high blood pressure and blood sugar,the message was clear:change my life now.
Exercise to me was as fun as bathing the cat.When I had physical education in high school,I thought of push-ups and running laps(俯臥撐和跑圈) as punishment.I could never imagine exercising could be fun or a routine part of life.
Over my summer break,I met a friend who worked out regularly.Danica cooked healthy meals from basic fresh foods.She helped me learn to eat smaller portions(份) and eat fewer desserts.Danica and I worked out with fitness programs four times a week.I began losing about two pounds a week.I dusted my two-wheeler off and unsteadily rode it down the block.Then I started riding the bike to work about a mile and a half away.The tall fourteen-year-olds laughed at their wobbly(搖搖晃晃的) bike-riding mom.
Depressed one day,I went over to Danica's,not wanting to work out.
She asked,"What's wrong?"
"Everything,"I told her."Today,I went to Virginia's to give her a birthday present,and she was labeling everything in her house so the kids know who gets what after she dies.She's having surgery in a week.What an attitude!Then I found out I am overdrawn(透支) in both of my checking accounts."
"Well,"she said with a cheerful smile,"We're going to exercise and you'll feel better!"
Exercise had not just become a habit,and it was a way to lift my mood,combat stress,stay flexible and slow down aging.
31.What mainly caused the author to go to hospital?C
A.She suffered from serious high blood pressure.
B.She became too overweight at forty-six.
C.She had too much pressure.
D.She got a serious headache.
32.According to the text in high school,the author used toA.
A.take very little exercise
B.be punished by teachers
C.consider exercise to be fun
D.regard bathing the cat as exercise
33.The author's son laughed atB.
A.her habit of eating smaller portions
B.her way of riding a bike to work
C.her measuring herself every day
D.her attitude towards eating sweets
34.The author felt depressed one day becauseB.
A.she didn't want to work out.
B.she couldn't make ends meet
C.she would have her surgery soon
D.she couldn't buy Danica a birthday gift
35.From the last two paragraphs,we can learn that the authorA.
A.develop the habit of exercising
B.still didn't feel like exercising
C.didn't find ways to change her life
D.got rid of all her diseases.

9.This habit was picked from my teacher back in 1988.Back then it seemed trivial(瑣碎)and not likely to make any significant influence on my life.(16)D
The habit that has made the greatest influence on my life is scheduling.In my mind,it is the tiny daily habit that indeed can be life-changing.Scheduling is not just about the ordering of tasks throughout the day.(17)EIf you are able to design the right schedule and follow it,you are able to gain massive rewards for your work.
(18)FHowever,everything is likely to boil down to the most precious asset(財(cái)富),namely time.If you are able to master your time and follow the schedule,you will not lose any minute doing things that do not matter or add no value.The tiny daily habit of scheduling your day is important.In the short term,it might seem boring and inefficient.(19)GIt can provide you with the greatest opportunity possible.

A.Master your time
B.Only time will tell.
C.Forming tiny daily habit is not an easy task for us.

E.It is about the proper allocation and usage of your time and effort.
F.One can endlessly argue about the things that have the biggest value in our lives.
G.However,in the long run,the habit of scheduling your tasks and plans will pay off.

3.It is not only praise or punishment that determines a child's level of confidence.There are some other important ways we shape our kids-particularly by giving instructions and commands in a negative or positive choice of words.For example,we can say to a child"Don't run into traffic!"or"Stay on the footpath close to me."In using the latter,you will be helping your kids to think and act positively,and to feel confident in a wide range of situations,because they know what to do,and aren't scaring themselves about what not to do.
Actually,it is all in the way the human mind works.What we think,we automatically rehearse(預(yù)演).For example,if someone offered you a million dollars not to think of a blue monkey for two minutes,you wouldn't be able to do it.When a child is told"Don't fall off the tree,"he will think of two things:"don't"and"fall off the tree".That is,he will automatically create the picture of falling off the tree in his mind.A child who is vividly imagining falling off the tree is much more likely to fall off.So it is far better to use"Hold on to the tree carefully".
Clear,positive instructions help kids to understand the right way to do things.Kids do not always know how to be safe,or how to react to the warning of the danger in negative words.So parents should make their commands positive."Sam,hold on firm to the side of the boat"is much more useful than"Don't you dare to fall out of the boat?"or worse still"How do you think I'll feel if you drown?"The changes are small but difference is obvious.
Children learn how to guide and organize themselves from the way we guide them with our words,so it pays to be positive.

32.Positive choice of words helps kids toA.
A.build up their confidence          
B.learn in different situations
C.improve their imagination           
D.do things carefully
33.What can we infer from Paragraph 2?B
A.A child will act on what is instructed.
B.One can't help imagining what is heard.
C.A child will fall off the tree when told not to.
D.One won't think of a blue monkey when given money.
34.Which of the following commands helps kids to be safe?C
A.How do you think I'll feel if you get hurt?
B.Don't play by the lake.
C.Fasten your seat belt.
D.Don't you dare to walk through the red light?
35.The main idea of the passage is thatD.
A.praise makes kids confident         
B.right instructions keep kids safe
C.clear commands make kids different 
 D.positive instructions guide kids.
