You’ve likely noticed them by now. School buses are back on the street packed with students. Many of those kids step off the buses with a potential health danger over their shoulder — a backpack filled with homework.

Backpacks come in all shapes, sizes and colors. It is a fun way for any girl or boy to express their styles. Some are simple, some covered with cartoon characters, many equipped with special compartments for every tool a student needs, like pencils, notebooks and books.

Yes, they are practical, but a heavy backpack can injure muscles and joints. Wearing a backpack incorrectly can lead to severe back, neck and shoulder pain, as well as posture problems. When a backpack filled with books is placed on a boy or girl’s shoulders incorrectly, the force of the weight can pull the child backward, so the child may bend their hips forward or arch their back.

Pay attention to detail when selecting a backpack; choose one that is equipped with a comfortable back, waist and wide shoulder straps. Narrow straps can dig into a child’s shoulders and affect circulation and nerves. The heavy load danger is not just for kids 12 and under. Middle and high school are at risk, too. They are carrying heavier books home daily.

Luckily, back pain created by backpacks is preventable. Parents should talk to their kids about lightening the load. You can even use a bathroom scale. The backpack should not weigh more than 10 percent to 15 percent of your child’s weight. If your child weighs 80 pounds, the pack should not weigh more than 8 to 12 pounds. If your child weighs 140 pounds, the pack should not be heavier than 21 pounds. Most importantly, if your child talks about numbness or weakness in the arms or legs, contact a physician.

1.What do students’ backpacks reflect according to paragraph 2?

A.Their hobbies. B.Their styles.

C.Their characters. D.Their needs.

2.What is paragraph 3 mainly about?

A.Students’ heavy loads. B.Wearing backpacks incorrectly.

C.Dangers of heavy backpacks. D.Weight of heavy backpacks.

3.Which backpack is more suitable for a child weighing 100 pounds?

A.With wide shoulder straps weighing about 10 pounds.

B.With narrow shoulder straps weighing 16 pounds.

C.With wide shoulder straps weighing 20 pounds.

D.With narrow shoulder straps weighing 15 pounds.

4.Who are the intended readers of the text?

A.Children. B.Doctors.

C.Teachers. D.Parents.

The idea of being quarantined (隔离)hadn't seemed like a major issue until we all began to realize all of the things that get taken away when school goes. We had taken our "normal" lives for granted and this pandemic (流行病)was proof.1. Throughout our entire educational lives, we students have always jokingly said we wanted school to be cancelled. We didn't realize, however, that all the activities associated with being in school would be taken away too. School has an influence on so much more than we actually think.2.

While in my room, my sixth-grade cousin opened my door and expressed how she didn't want school to be cancelled because it was the only reason she left the house.3. This is when I began to acknowledge the true impact school has even on the youngest of children. As a sixth-grader, her only known duty so far was to go to school, learn, maybe participate in a sport or two, and socialize with others. When eating dinner my uncle shared with us that he has no work until April 15. My other aunt and uncle now had to play a larger role than ever imagined in the education of their children. Without one-on-one interaction with a teacher, it's crucial to ensure that their kids of ages 4 and 7 continue learning. During this school closure, parents and students alike have noticed the direct effect social media has on our reactions.4. Many of these opinions either contribute to hysteria (歇斯底里)or attempt to tell us that we may be overreacting.

5. This pandemic has effects of all different levels of significance, many of which can never be replaced nor made up. The death toll it has worldwide is even more frightening to think about. Everyone is affected in one way or another by this crisis, but let us not forget what school has taught us about ourselves as a community ... that we are stronger together.

A.Initially, everything seemed to be under control.

B.She explained how she would be bored without school.

C.It has provided us with friend groups, hobbies and passions.

D.Since this didn't affect us at all, we continued about our daily lives.

E.Opinions of all sorts are broadcast regardless of the accuracy they contain.

F.We took for granted the simplicity of walking across a stage with a diploma in our hands.

G.However, the impact the coronavirus has had on the world is a generation-changing event.

From the end of next year, all shops, market stalls and takeaways in Wales will be obliged to charge up to 15p each for plastic or paper bags. Wales is to become the first part of Britain to ban free carrier bags after deciding that efforts by supermarkets to cut waste have proved ineffective.

Jane Davidson, the Welsh Environment Minister, said that the revenue（收入） would go to a new independent body, which would spend the money on local environmental projects. She admitted that a small number of people might switch to shops in England, where there are no plans to charge for carrier bags. She said that tough action was necessary. Ms Davidson, a Labor member of the Welsh Assembly’s ruling Labor-Plaid Cymrucoalition, hopes the ban will embarrass her counterparts（对应的人） in England, Scotland and Northern Ireland into similar action.

Wales is planning to use a little-known clause(条款) in last year’s Climate Change Act, which enables the government to outlaw free bags. Ms. Davidson said: “We want to encourage people to think about what they do. All the other ministers are still signed up to the voluntary agenda. You will see a different message from me.”

Last week the media revealed that Tesco had published misleading figures giving the impression that it had met a voluntary target to halve the use of plastic bags in three years. Seven supermarket chains reported last month that the total number of free bags they had issued had fallen by 48 percent to 450 million a month in the three years to last May. The figures masked that Marks & Spencer, the only chain to charge for bags, had made much faster progress than its rivals. It cut bag use by 83 percent after introducing a 5p charge last year. Ms. Davidson said that banning free bags would encourage a wider shift to a less wasteful society. She was considering a charge of between 5p and 15p, but indicated that she favored the upper end of the range.

1.Which city is the first part of Britain to ban free carrier bags? _______

A. Wales　　 B. England

C. Scotland　　 D. Northern Ireland

2.A certain amount of purchase will take place in England because_____________.

A. the carrier bags are cheaper there　　 B. the goods there are free

C. the goods there are cheaper　　 D. the carrier bags are free there

3.The government cited a little-known clause in last year’s Climate Change Act for the purpose of _________.

A. arousing public’s sense of reducing waste　　 B. reducing the customers’ resistance

C. promoting charging bags with legal means　　 D. enabling supermarket to cut waste

4.According to Ms. Davidson, she preferred a free bag’s charge to be ________.

A. 5p　　 B. 15p

C. between 5p and 15p　　 D. above 15p

The scientific world continues to be amazed by the speed of the development of cloning. Some scientists now suggest that the cloning of humans could occur in the near future. Despite the benefits of cloning, however, certain ethical (道德的) questions concerning the possible abuse (滥用) of cloning have been raised. At the heart of these questions is the idea of humans influencing life in a way that could harm society, either morally or in a real physical sense. Some people object to cloning because it allows scientists to "act like God" in the handling of living organisms.

The cloning of Dolly raised the debate over this practice to a whole new level. It has become obvious that the technology for cloning Dolly could also be used to clone humans. A person could choose to make two or ten or a hundred copies of himself or herself by the same techniques used with Dolly. An active debate about the morality of cloning humans arises. Some people see benefits from the practice, such as providing a way for parents to produce a new child to replace one dying of a fatal disease. Other people worry about humans taking into their own hands the future of the human race.

At the beginning of the twenty-first century, many scientists say the controversy over the ethics of cloning humans is overstressed because of the unpredictability (不可预测性) of cloning in general. While scientists have cloned animals such as sheep, mice, cows, pigs, and goats, fewer than 3 percent of all those cloning efforts have succeeded. The animal clones that have been produced often have health problems. Scientists believe the rapid reprogramming in cloning can introduce random (任意的) errors into a clone’s DNA. Those errors have altered individual genes in minor ways, and the genetic defects (缺陷) have led to the development of major medical problems. Some scientists say this should make human cloning out of the question, but others argue that cloning humans may actually be easier and safer than cloning animals. Whatever, I agree that further research in the field of cloning is needed.

1.Some people are against cloning of humans because they think _________.

A．the practice takes too much time and money  B．the cloning technology is still not mature  C．humans control the future of the human race           D．the population in the world will be too large

2.Some scientists think the debate over ethics of cloning humans is overstressed because ____.

A．cloning of human beings is completely impossible                  B．the result of cloning can’t be predicted in general                    C．cloning of animals is a failure               D．there are big errors in a clone’s DNA

3.We can learn from the text that _______.

A．cloning of humans is a very controversial issue B．the cloning of Dolly begins to raise the debate over cloning of humans    C．there are medical problems in cloning animals         D．cloning humans is easier and safer than cloning animals

4.The text is mainly about _______.

A．the benefits of cloning                   B．the ethics of cloning C．the history of cloning  D．the defects of cloning
