A
Do teenagers in small villages do chores at home? How about the teenagers in big cities? Here is a survey. We asked 4, 000 teenagers in China several questions. Half of them come from big cities like Beijing, Shanghai and Guangzhou. The others are from small villages. We made a diagram(图表)of the result of our survey. Let?s
have a look at it.
We found out that teenagers from small villages do more chores than those from big cities. Maybe it is because they live a harder life. Our advice to parents in big
cities is that parents should give their children some chores to do. Doing chores teaches teenagers to take care of themselves.

A. making the bed
B. taking out the rubbish
C. folding the clothes
D. doing the dishes
5. Which of the following is TRUE according to the passage?
A. Most of the children in China don?t do chores.
B. Doing chores can help teenagers look after themselves well.
C. Teenagers from small villages have an unhappy life.
D. Teenagers from big cities should do as much as those from small villages.
B
Most children don?t enjoy doing chores. They like playing computer games rather than cleaning the rooms. But in Australia, Jim and Robert?s mother, Mrs. Black, has good and proper methods to get their children to do housework.
Here is an example.
“Mom, have you worked out next week?s chores? Let Jim and me choose the cards. I can?t wait. It?s fun! ”
When Robert shouted out, his mother had already put all the cards on their big table. On the cards, there are some words like these, “s weep the floor, clean your bedroom, help mom cook, wash vegetables, make beds, feed the fish, cut the wood,
7
clean the bathroom” and many others, Jim and Robert chose two cards for each day from Monday to Friday. Then they would hang them on the weekday task board. Jim likes to clean the bathroom, so he picked up the card “clean the bathroom”. Robert loves to make the bed so he picked up his favorite card. Jim again picked up “wash vegetables” and Robert chose “feed the fish”. Soon the two boys were happy to take away all the cards.
To help the children do chores, their mother thought hard and came up with this idea. Of course, the parents did the chores at weekends and left Jim and Robert two days free.
6. From the passage we know that most children like__________.
A. doing chores
B. playing computer games
C. playing cards
D. doing housework
7. Jim and Robert chose__________ cards for the weekdays from Monday to Friday.
A. two
B. four
C. eight
D. ten
8. Jim likes to__________.
A. clean the bathroom
B. make the bed
C. feed the fish
D. sweep the floor
9. The underlined phrase “came up with”in the last paragraph probably means“__________”.
A. looked at
B. gave up
C. thought of
D. believed in
10. Who did the chores at weekends?
A. Jim.
B. Robert.
C. The parents.
D. The whole family.

八、阅读表达(10分)
阅读短文, 根据要求完成下面各小题。
answer, “No, never. ”Most of us think cleaning the bathroom
or cooking dinner is very boring. However, the fact is that
someone has to do it. Most of the time, our parents have to do
the housework.
Doing the housework is really not as bad as it sounds. If we all do some housework, it will seem less annoying. Why should our mother wash our dirty dishes? Part of grown-ups are able to take care of themselves. Doing some housework will show that you are becoming more mature(成熟的)and independent.
(A)Some of us may think that we are so busy that we can?t do the housework. But most parents work all day and are then expected to keep a clean house! Dividing the housework among the whole family will make everyone?s job easier. It s eems much better to have three or more people together keep the house clean.
Cooking is one part of the housework that can be very fun if you are creative. Learning how to cook a meal is a great skill. (B)If you learn how to cook your favorite food, you will show others that you have a very special talent.
Don?t be afraid to help around the house; your parents will greatly appreciate it. The next time you see something that needs to be done at home, do it yourself and show that you can do anything!

(2)直线BD必经过点O. (3)四边形DEOC与四边形BFOA的面积必相等. (4)△AOE与△COF成中心对称,其中正确的个数为( ) A.1 B.2 C.3 D.4 【解析】选D.△ABC与△CDA关于点O对称,则AB=CD,AD=BC,所以四边 形ABCD是平行四边形,因此点O就是?ABCD的对称中心,则有:(1)点E和点F,点B和点D是关于中心O的对称点,正确;(2)直线BD必经过点O,正确;(3)四部编版三年级语文下册第一单元评价测试卷
