I’d like to tell you anything about the one -day tour on last weekend. We went to the Wetland Park by bike, with an aim of advocating a green trip. In addition, our main task was do something meaningful, but we volunteered to pick up the rubbish in the park. Besides, we also participated in other interesting activity. We went boating in the river. The most excited activity was the fishing competition, during that I won the first prize. We all had a good time here. When we return in the afternoon, it was already five o’clock.

As the COVID-19 forces students to stay home, online learning has seen a sharp rise among students. Since late January, China has delayed starting the new school semester and encouraged students to study at home over safety concerns.
Besides what has been arranged by your schools as your study routine, what can you gain from online learning?1.
To successfully learn online, you need to dedicate a significant amount of your time, consistently attend the program, concentrate while studying and fully stick to your learning process, just as you would do for a regular course.
To stay on track with your online course, always keep in mind what you hope to complete by the end of it.2. Estimate how much time each task will take to complete. Keep detailed notes and review them often.
A study plan is important to online learning.3.Online learning needs to be well organized. Create a study calendar that will help you remember all the important dates like online exams or deadlines for your assignments.
When you feel yourself losing concentration, consider taking a short break or sopping for the night.4.
Taking online courses can be very convenient for many people.5.It requires time management skills, self-discipline, willpower and motivation.
A.Make a goal.
B.It can also offer you a good experience for self-learning.
C.Most importantly, you need to plan ahead with a good calendar system.
D.Online course companies also adopted special measures to meet students’ demands.
E.However, it may be challenging for some to successfully complete their online courses.
F.A to-do list is useful to carry out your study plan and to stay on track with your studying.

You can’t see it with your own eyes，but your smart-phone is likely to be covered with bacteria- perhaps even more so than your toilet seat. That's a lot of dangerous microbes（微生物）floating around, and yes, it is terribly dirty.
In this age of global travel and trade, it’s more important than ever to cut down on possible routes of infection and to stop bacteria and viruses spreading from person to person. Part of that means making sure your phone isn’t sending anything more than data.
And besides the potential health risks of a dirty phone, there's also the simple annoyance of looking at a screen that’s covered in fingerprints and other oily spots that are part of life with a smart-phone.
In short, you’ve got plenty of reasons to regularly give your phone a thorough clean. Not just during a pandemic（大流行病），either-we should be thinking about keeping our phones bacteria free all the time, says microbiologist Paul Turner, a professor at Yale University.
After all, we touch our phones all the time and many of us are relatively careless about cleaning them. “It sets the stage for kind of concern,” Turner says. “People could be handling phones and picking up any bacteria or virus that can attach to a surface and survive for a period of time.”
Take SARS-CoV-2, the corona- virus（冠状病毒）that causes the COVID-19, for example. Scientists are still trying to get solid evidence, but early research suggests that it can survive on plastic or stainless steel（不锈钢）surfaces for two or three days. That means you could be washing your hands perfectly well, but immediately picking the virus up again as soon as you reach for your phone.
You could be doing everything right（like washing your hands and staying away from people），but
if there’s a contaminated surface in your home or your pocket, you could expose yourself to the virus anyway, Turner says.
1.Why does the author mention the toilet seat?
A.To draw a vivid picture of a dirty phone.
B.To show how dirty a toilet seat is.
C.To add some background information.
D.To introduce a topic for discussion.
2.What can we learn in Paragraph 6?
A.Simply washing our hands is not enough.
B.Scientists have got solid evidence of the COVID-19.
C.The corona-virus can survive on smooth surfaces for 2 or 3 weeks.
D.The author suggests washing our hands before using our phones.
3.What do the underlined words “contaminated surface” refer to in the last paragraph?
A.A stainless steel. B.A deadly virus.
C.A clean phone. D.An infectious phone.
4.What is the main idea of the text?
A.You may get infected with your dirty phone.
B.You are supposed to wash your hands.
C.You’d better clean your dirty phone.
D.You’d better throw away your dirty phone.
