It's hard for women to be a“good”mother and they have to show the
world that they aren't“bad”. If a woman works outside the home, she's leaving her children behind; but if she stays at home, she will give her children too much attention. In some ways, things are getting worse.
Years ago, some women chose to stay at home and spent five years
shaping their children's personalities(性格) after their birth. In recent years,
however, some scientists have been telling mothers that the first three years of life are the most important, while others think that all the most important
things happen during the first year.
But the worry about doing the right thing to make the child perfect may be the worst thing for the child and the mother. A study shows that mothers
should be relaxed. Here are the reasons.
First, it is not harmful to children if their mothers go to work. If mothers pay less attention to their own needs, it won't be good for their children and family. Second, there is no key moment(时刻) in early childhood. It is sure
that it's good to give children attention from the start, but one wrong step will not change their lives.
Parents cannot control all the possible ways their children may take.Many things can affect children: genes(基因) , life experiences and education.
( )1. If a mother stays at home, she will .
leave her children behind
B. care more about the family
C. give her children too much attention
D. pay too much attention to herself
( )2.Why did some women spend the first five years with their children at home
A. To show love to children. B. To make children perfect.
C. To make children relaxed. D. To shape children's personalities.
( )3.According to the text,the following things can affect children EXCEPT .
A. education B. genes C. children's nature D. life experiences
( )4. The study gives reasons why mothers should be relaxed.
A. two B. three C. four D. five
( )5. We can read the text from a(n) .
A. poster B. newspaper C. novel D. interview

In 2010,the world's population was about 6.8 billion.More than three billion people live in Asia now.That's almost half of the world's population.
China has the largest population in the world and about one fifth of the people in the world live in China.Because of the large population there is less living space for each family.And it is difficult for lots of people to find jobs.At the same time,the large population has caused many other difficulties for the whole nation.For example,it is hard for China to supply energy and water to satisfy people's daily needs.Most cities are more crowded than before,and the traffic is much heavier.Natural environments are becoming worse and worse.The large population has been a serious problem.
So far,our government has taken many measures to control the population.One is known as the one-child policy.It has worked well in controlling China's population.Thanks to the policy,China is developing quickly and people's living conditions are improving rapidly.However,the population problem is still serious in China.We still have a long way to go.

五、句子还原。
Some people think only school children don't agree with their parents.
However, it is not true. 1 If it's hard for you to communicate with your
parents, don't worry about it. Here is some advice for you to bridge the
generation gap(代沟).
●Don’t argue(争辩) with your parents. Don’t come to your parents when you are angry. Your parents probably won't consider your ideas if you are
shouting at them. And you can't express yourself well if you are angry. Go
someplace to calm down. 2 Then think about what you want to say to
your parents. If you don't think you can speak to them at the moment, try
writing a letter.
● 3 Maybe you and your parents disagree on something. You can
keep your disagreement and try your best to accept each other. Of course,your parents might refuse to compromise( 和解)on something. In these situations,it is especially important to show love and respect for them.This will keep your relationship(关系) strong.
●Talk about your values(价值观).The values of your parents are probably different from those of your own. 4 Understanding your values might help them see your purposes in life.
5 So it’s worth a try.
A. Try to reach a compromise.
B. Tell your parents what you care about, and why.
C. Make sure you understand why you are unhappy.
D. Communication is a problem for parents and children of all ages.
E. A good parent-children relationship makes you a happier person.
1. 2. 3. 4. 5.
