It was said that school should not start before March. The exact start time of school will depend on situations and further notices.However, many parents are very worried that putting off the start of school may affect(影响)children’s studies. If they have such a long winter vacation, children will not learn any knowledge, read books or study at all. They may forget what they have learned before. Staying at home for a long time will make them keep eating, sleeping and playing, which seriously affect their physical andmental health.In short, the close of school influences learning and develops bad habits, so how should we avoid these problems? Local education departments have also issued a notice, that is, to organize online teaching and create a network platform(平台), where necessary courses will be shown every day, and online teaching will be given by excellent teachers of the subject, and students can learn at home through computer or mobile network.It should be said that such a method is very good. It can not only keep students indoors and not worry about the infection(感染) of the disease, but also make them study at home, improve their learning ability, and truly achieve“no suspension of classes”. Both the platform itself and the recorded lesson resources are more useful, and are welcomed by parents and teachers.Of course, except for learning at home, it is also necessary to teach children about health knowledge, especially how to keep away from touching virus and other knowledge popularization; at the same time, it is also necessary for children to do some physical exercises or some games, which is good for physical healthat home.11.

Students would rather go to school.B. The date of going to school is decided.C. Online teaching will help students study.D. Parents believe children can teach themselves.15. What’s the best title for this passage?A. A Special Way to Learn at HomeB. A New War with a New ChanceC. A Way to Keep Mentally HealthyD. A Method to Make Parents WorriedD.Many of us don’t pay much attention to the importance of eye care. It is said that if you take care of your body, then you can surely be healthy. That is why our eyes should be given a lot of care. Natural eye care should be put in a number one place.There are several causes leading to poor eyesight like not eating enough food, genes (基因) and aging (老化). Televisions,computers and reading are also the causes of having poor eyesight. If you happen to work in front of a computer, you’d better take a break every once in a while.Something dirty can cause redness and it will make you feel uncomfortable. It is bad for your eyes, too. If this happens, the best way is to clean your eyes by using cold water. Y ou must also try your best to protect your eyes from harmful things.

Remember that vitamins A, C and E are good for eyes. Try to eat food groups that have these vitamins. And you should do eye exercises because they protect your eyesight, too. If a person exercises regularly (定期地) and eats the right kind of food, hiseyes will stay in good condition for a long time.All above are natural ways of eye care that help us keep healthy eyes.
