文章大意：本文是写给父母的返校指南。

【推荐1】During COVID-19, we have prepared a back-to-school guide for parents to check. Join us to prepare for your kid’s back-to-school life together!

	The COVID-19 is still spreading. If your kids go to school alone and do not go home in time after school, that’s probably because they play games or hang out with friends after school. Parents will certainly worry that their kids might be going to a dangerous place. So parents should ask their kids to get home at a regular time and never go to dangerous places.
	The digital world is so interesting that kids can easily be attracted by games, videos, e-books, social interactions(互动) and so on. Once it is out of control, the kids will easily lose themselves in it. Kids aged 8—18 spend a lot of time on screen nowadays, and this is one of the reasons why they’re short-sighted, sleepy and fat. So parents should limit(限制) the screen time available to kids.
	If your kid is often in a bad mood(情绪), stays in the room most of the time and has no interest in social activities, you must pay more attention to him or her. If these signs have appeared, they are likely to be lonely at school or come across sad things such as bullying(欺凌). They need the care then. So parents should keep an eye on their kid’s behavior, and give love and care in time.

1. Who is this back-to-school guide written for?

A．Students.

B．Teachers.

C．Parents.

D．Schools.

2. According to the guide, parents will certainly worry about their kids ________.

A．health

文章大意：本文介绍了如何制定自己的新年决心。

【推荐2】New Year’s Day is coming. I believe that most of you have your own New Year’s resolutions. 1 First, your New Year’s resolutions should be good for you. 2 “Going to bed later” is not a good resolution. It is not good for your health. You should make resolutions like “drinking milk for breakfast every morning, doing more sports to help you be in good health.” 3 “Studying harder and spending less time watching TV” are also good ones.

4 Be sure that you can keep your resolutions. Don’t make your resolutions too high. Flying to the moon is a difficult resolution for anyone. 5

After you make some good and realistic(现实的）resolutions, don’t forget to make a plan. Write down what you need to do every day, and then do it.

A．What are you going to be in the future?

B．But what kind of resolutions should you make?

C．You should keep your resolutions small and simple, so you can keep them.

D．Be sure that they can improve your studies or make you healthier.

E．You should eat more fruit and vegetables.

F．The resolution “stopping eating junk food” is also a good one.

G．Second, your New Year’s resolutions should not be very difficult to keep.

【推荐3】Your comfort zone is a place, an activity or a situation in which you feel free from worry and things are within your ability or control. 1 When you break free and try new things, you’ll be more productive and get more unexpected changes.

Here are some ways to break out of your comfort zone without going too far.

•Do everyday things differently. 2 Try a different diet. Don’t be upset if things don’t work out in the way you planned.

• 3 if you think the challenge you’ve picked for yourself is so difficult that you can’t rise to it, don’t do it at once. You can make it a multi-step process that will let you slowly climb that mountain.

•Trust yourself and make snap decisions. Perhaps you are more comfortable weighing all of the possible choices several times, but sometimes making a snap call is just in order to get things moving. 4

However, you can’t live outside of your comfort zone all the time. You need to come back from time to time to review your experiences. In this way, you can put what you’ve got into your day-to-day activities. 5 It’s a natural state. Don’t take your comfort zone as something holding you back. We all need that headspace where we’re least worried and stressed so we can process the good we get when we leave it.

comfort zone             舒适区
multi-step                  多步骤的
snap                         匆忙的
headspace                  精神状态

根据材料内容，从下面五个选项中选出能填入文中空缺处的最佳选项，使短文意思通顺，内容完整。

A．Break the activity down into small steps.

B．But stepping out of it also has good results.

C．Doing so can teach you to trust your decision.

D．Your comfort zone is neither a good thing nor a bad thing.

E．Ride your bike instead of taking the bus to school.
