Please leave your comments(评论)about this question.CommentsDavid Children often get a lot of homework and have much stress about school.So they don't have time and energy to do chores.Parents should do the housework insteadof the children.Bob Doing chores helps children to be more independent.It also teaches them life skills such as washing clothes,cooking and cleaning.Kids should be able to do thingsby themselves.They can't live with their parents forever.Mary Doing chores may take a long time.If you are not good at doing chores,you may get into trouble like breaking things or hurting yourself.So there is no need forteenagers to do chores.Alice We students sit on the chairs all day to study and play with our phones sometimes after school,not wanting to exercise or do other things at all.It is bad for our health.However,doing housework,from doing the dishes to sweeping the floor,can makeus move around and keep away from our phones for a while.Peter If we take the responsibility to do it,parents will be very happy!In fact,all the family members,not just our mothers,should share the housework.It shows ourlove to the family and the idea of fairness.41.The passage is from______________.A.a storybookB.a reportC.a website42.From David's words,we can know that_______________.A.David gets a lot of stress from houseworkB.David wants to do housework together with his familyC.David thinks that doing chores should be parents' job43. Which of the following is TRUE according to Alice's words?A.Doing chores is good for children's health.B,Children just want to make their parents happyC.Doing chores can make children independent.44. What does the underlined word “responsibility" mean in the text?A.责任B.机会C.挑战45. Who has the similar idea with Peter?A. David.B. Bob.C.Mary.CIt's normal to have different ideas from others. People may think that disagreement causes fights. However, this is not true, If we communicate with others in a proper way, disagreement will also be happy and educational.46First of all,we should listen to others carefully when they show different ideas. Sometimes we may want to show our ideas too much,so we don't really listen. 47When you listen to others, give them your full attention to show them that your are interested in what they are saying.Secondly, when somebody doesn’t agree with you, don't treat him in an unfair way.48 Instead, we should use the facts, not your feelings to communicate with others. Try to realize that their ideas cover something useful, though you don't have to agree with them.49 When you show your opinion, make sure you are using “I” language, not “we language. The use of “we” may let others feel that the speaker feels like ganging together (拉结派).It's not helpful to reach an agreement.All in all, if we know the truth of communication, it'll be easier for us to reach an agreement. 50 It is all about listening and understanding. What's more, rememberto respect(尊重)each other though we have different opinions.A. It means we shouldn’t get angry with him or shout at himB. But careful listening is the first step to know others betterC. Thirdly, be sure that you are speaking only for yourself.D. Make sure your friends will agree with you finallyE. Then what is the truth of communication?F. Here's some advice.DAccidents happen more often than you think.Every year in China,3.2 million people die in accidents—that's almost six people every minute.Scientists say that the 10 minutes after an accident can make the difference between life and death.This is why learning first aid(急救)is so important for everyone.Common first aid training teaches you how to deal with emergencies(突发情况),do CPR(心肺复苏),and treat things like burns,bleeding and broken bones.You can learn first aid by visiting the official website(官方网站)of China First Aid training.You can also read books or watch videos that can be found on free apps.Going to some first aid camps is also a good idea,and it takes only a few hours to learn some useful skills there.Knowing the importance of learning first aid skills,many schools in Taiyuan have started first aid training lessons.After taking these lessons,a lot of students not only learned how to deal with small accidents,but also learned to keep calm when facing them.Taiyuan Daily ReportOn Mar.21st,a man had a sudden heart problem at the subway station.As soon as he fell down on the floor,several warm-hearted citizens(市民)came to help.Zhang英语试题参考答案及等级评定建议一、补全对话(每小题2分,共10分)21—25 BEAGF二、完形填空(每小题1分,共10分)26—30 BCABC31—35 ABABC三、阅读理解(每小题2分,共40分)(A)36—40 FTFTF(B)41—45 CCAAB(C)46—50 FBACE(D)51.Because the 10 minutes after an accident can make the differencebetween life and death.52.They can visit the official website of China First Aid Training or readbooks./By visiting the official website of China First Aid Training or reading books./They can watch videos that can be found on free apps orgo to some first aid camps./…(任写两种方式即可)53.(It will take)1.5 hours/one(an)hour and a half/one and a half hours.54.(We can learn)Zhang Hua not only learned how to deal with smallaccidents,but also learned to keep calm when facing them(at school)./We should learn first aid skills and try to help others in need (just likeZhang Hua)./It's necessary for students to learn first aid skills./.…(言之有理即可)55.I learned how to deal with bleeding./…I learned it on the Internet./At school./…(开放性答案,言之有理即可。

Studies show that kids start watching cartoons on TV at an early age of six months, and by the time they reach the age of two or three, they become fans of cartoons and they would like to spend much time on them. Parents often see this as a problem because most of the kids are too crazy (狂热的) about watching cartoons. Parents think if kids spend too much time on cartoons, they won't do well at school.Some people think it's good to watch cartoons. They help the working parents the most because parents can do a lot of work when their kids watch cartoons on TV.When children watch educational cartoons, they get to learn many things. Cartoons also help to improve children's language skills. Educational cartoons help children try different languages. Kids can learn English well with the help of those cartoon programs. At the same time, some kids can learn about the friendship and teamwork from the cartoons. It is good for them to get on well with their friends and classmates.So sometimes it is meaningless to stop kids from watching cartoons, but parents shouldmake sure that their kids are watching the right things.31. When do kids start to watch cartoons on TV?A. When they are six months old.B. When they are two years old.C. When they are three years old.D. When they are six years old.32. What can we know from the passage?A. Parents need to watch cartoons with their kids together.B. Children should not watch cartoons when they are young.C. Some parents think it's bad for their kids to watch too many cartoons.D. Children like cartoons because their parents don't take care of them.33.
