One main difference between viruses and bacteria is the method of reproduction. A bacterium is a completely independent and self-reproducing unit. When the time is right, bacterium will divide its DNA and RNA genetic material in two. This is how bacteria live in almost every environment on Earth, including non-living things like rocks or plastic.

A virus, on the other hand, cannot reproduce without a living host. A virus may lie for thousands of years before finally coming into a suitable host. Once it enters the body of a host, a virus will get in the ling cell. Once inside a living cell, a virus takes the place of the living cell's DNA or RNA genetic instructions with its own. Those instructions are usually to make as many copies of the virus as possible.

Ninety-nine percent of all known bacteria are considered useful to humans, or at least have no bad influence. But most viruses, on the other hand, serve no good purpose. Their only purpose is to create more viruses in order to make themselves continue to live.

Bacteria are alive, which means they can be killed by some form of chemical things. Antibiotics (抗生素) can kill bacteria. Viruses, by comparison, are not considered living things. They cannot be 'killed' in the same way as antibiotics kill bacteria. In fact, any medicine is useless for virus' infections. The disease must run its course until the body can make a successful protection on its own.

In Canada, volunteering is a quite common thing among people of all ages, as they believe that being helpful is one of the most important qualities to have. There are many kinds of volunteer work. Chances to help are everywhere, including in schools, shopping malls, or even people's gardens.

Now, I'm volunteering for a charity (慈善機構). My job is to help the teachers at the charity's Chinese language school. I teach in a preschool class, where students are aged from 3 to 6.

When I first started, I was quite nervous as I'd never worked with little kids before.

Then, as time went on, I became more familiar with the students. One teacher asked me to help the youngest girl in the class draw a picture based on the word "grateful". As I was drawing and talking with her, I felt warm and peaceful and suddenly realized that it was not that difficult to work with children. When the class was over, I breathed out deeply, feeling really excited and even a little bit proud of what I'd done.

Volunteering gives us a chance to change someone's life, including our own. It gives us the satisfaction of helping others. Volunteering is also a great way to give back to society while developing social skills and meaningful experience for the days ahead. That's also the reason why Canaan high school students have to volunteer for at least 40 hours in order to graduate. I think helping other always good.

【1】Canadian students spend their weekends quite different from Chinese students.

【2】It's normal for Canadians to offer help in different places.

【3】Now, the writer is volunteering to teach the kids in a primary school.

【4】The writer managed to help a girl in the class, and the teacher was very satisfied.

【5】40 hours' volunteer work is one of the requirement for high school graduation in Canada.

First, always remember that you are sending messages to a real person, not just to a computer. 【2】 Also, remember that the person who receives your massage can not hear the tone of your voice, or see the expression on your face, so make sure your meaning is clear.

【3】 Don't take anything without paying for it unless it's free. Don't use information that someone else has written, and say it's yours. Don't read other people's e-mail-you wouldn't open your next-door neighbor's mailbox and open their mail, right? Do share your knowledge of the Internet with others. It's a big place with lots of information, and there are many new things to discover.

Remember that people judge (判斷) you by your words as well as your actions, so do try to write well. Good writing skills, as well as correct grammar and s petting, do matter. Send polite, well-written e-mail messages to others if you're uncertain about how to spell a word or which phrases to use, look it up. 【4】

It's okay to sow your ideas online in forums (論壇) like chatting room or message boards, but don't start arguments with people. 'Flame wars' (口水戰(zhàn)) in online discussions can be interesting to read, but are often unfair to other members of the group. 【5】

When you're online or offline, just as in 'real' life, try to respect other people's space, privacy and feelings. Remember, you are not the only one travelling on this highway!

A.Maybe this is somebody's habit.

B.There are lots of helpful books and websites.

C.Don't type anything online that you wouldn't say to someone's face.

D.Don't do anything online that you wouldn't do in the real life.

E.The fact is, this e-mail usually the way that people shout online.

F.Express your opinions, but remember that fighting online or offline is just not suitable.

B: Well, Ms. Black. 【1】

A: What did you argue about?

B: 【2】 She worried I might be late for school. But I've never been late.

A: Just about such a small thing?

B: 【3】 Even though I don't really want to. What should I do?

A: Children and parents often have trouble understanding each other. Although your parents were children once like you, they still have trouble understanding you.

B：【4】

A: That's it. In fact, your parents love you and want the best for you. 【5】 Instead, think about what your parents want you to do and why.

B: Thank you, Ms. Black. I know arguing doesn't help. I'll try to understand my parents and help them understand me.

A.I argued with my parents this morning.

B.My mother asked me to be quick, quick, quick!

C.When that happens, try to be calm and not argue.

D.I often argue with my parents about small things.

E.But things are not the same as when they were kids.

B: Bad! Actually, I have been feeling uneasy recently. I don't know how to deal with it.

A: I know how you feel. During the first two weeks of my staying at home, I was just 【2】 to stop checking my phone to follow its development every day. Seeing the rapidly 【3】 numbers of infections (感染) and deaths. I feared that the virus might make me sick.

B: You do get the 【4】. And every day there is tons of the information, I can't tell what is true. That makes me even more worried.

A: Remember you are not 【5】. These are normal feelings at this time. However, having these feelings isn't bad. It helps fight the virus.

B: What do you mean?

A: If people are afraid, they might take the government's orders seriously. Don't you think so?

B: I quite agree. These days, unless we have to buy something, my family seldom go out.

A: With the great 【6】 of all the people, the situation in our country is much better—there's been no more new infected or a few days in Wuhan.

B: That's been the best news so far. It can 【7】 people around the world to win the war against the COVID-19. I think your country's 【8】 could serve as a lesson for us.

A: I hear many people in Europe aren't satisfied with the government's orders. I know being 【9】 from going out means losing their freedom. But isn't it a better choice to wear face masks to protect themselves?

B: That is the 【10】 difference-we westerners think facemasks are for patients, not for healthy ones.

A: But in my opinion, in face of virus everyone should give up something we stick to.

B: You are quite right. Actually, we do start to change. Thanks for your caring.
