The novel coronavirus (冠狀病毒), which originated in the 【1】 city of Wuhan and has now spread to 120 countries, has much in common with seasonal flu. They are both viralinfections, share similar symptoms and crucially (關(guān)鍵地) can spread (傳播) 【2】 human to human. In the midst of flu season in much of the 【3】 hemisphere, telling the difference between the two will be vital in stopping its spread.

Human coronaviruses, of which there are four, can cause respiratory (呼吸道)infections similar to flu: while many symptoms are mild, both can lead to pneumonia (肺炎) and become lethal (致命的). 【4】, the novel coronavirus is more serious 【5】 a "typical influenza infection,(流感)"says Ian Jones, a professor of virology at the University of Reading.

"This virus appears to go 【6】 down into the lungs than would generally be the case. Therefore, it will give you symptoms of pneumonia (肺炎): the lungs becoming flooded, they don't function very 【7】 and the patient gets into breathing difficulty." While the mortality rates and symptoms of flu and novel coronavirus may 【8】 up being similar, humans' ability to fight off the viruses differs greatly.

Human shave naturally built up antibodies to seasonal flu and annual vaccines have been developed to fight it. During a pandemic (流行病), which the new coronavirus has the potential to become, "there 【9】 no immunity (免疫性) in the 【10】 so you have potential for a globle spread," warns Jones.

Police arrested a 19-year-old teenager yesterday who was involved in a ‘4-cats-killed’ case in Hong Kong. The case drew the public’s attention towards animal rights. Still, many people in Hong Kong would like to own a pet dog without giving serious thought to the consequences(后果).

We are concerned（關(guān)注） that some owners will drive away the pets once they have become useless. Homeless dogs and cats run here and there in the parks and streets. Many owners send their pets away for three reasons. Firstly, they have got diseases. Secondly, they are noisy and annoying（煩人）. Thirdly, they have broken the vase bought by a boyfriend. Because of these silly reasons, many pets lose their homes . More pets will be saved if we think twice before buying them.

We must pay attention to pets’ health. To have them injected(注射) with different types of vaccines(疫苗) at the correct age is necessary. You should always keep an eye on your pet. If they behave strangely, take them to an animal hospital at once. It’s dangerous for dogs to eat chocolate. Never leave your pets at home alone for a long time. Pets will show better behavior once they have developed good habits. Owners can take them to some training courses or teach them patiently at home.

Animal experts say that Hong Kong is not an ideal place for keeping pets at home. Hong Kong people are too busy and the flat spaces are limited. Above all, animals are an important part of nature. They should not be locked in cages. So, if you do not have the time and ability to keep them well, do not take them home. Please think twice before you pay.

Do you want to be happier? Well, you can do something about it. Some psychologists（ 心理學(xué)家） believe that 10% of your happiness is due to life conditions and 40% is the result of your own choices. Your own choices include how you manage your time at school, your relationships, your friends, your activities and your health. So you have a lot of control over how happy you feel.【1】 Here are some tips on how to do that.

Surround yourself with positive（ 積極的） people. Spend time with positive people and your ideas will become active. On the other hand, good friends will encourage, support, and lift you up when you're down.【2】

That's also true for the people that we work with Don't try to be perfect. Remember that nothing can ever be perfect.【3】

Instead think about what you already have. Think about what you've already done. Think of where you are today as a step towards tomorrow. Don't try to be perfect, just try to do things well﹣with excellence.

Focus on now. Don't think about all the things that can go wrong, like failing at school or your friend leaving you. Thinking like this only results in worry and stress, which is a waste of time and energy.【4】 Just worry about making today great, because the best way to be happy is just to enjoy each day.

Compare yourself to yourself, not to other people. There will always be someone smarter, or richer, or better looking or more successful than you. There will always be someone with a bigger house and a bigger boat than you. Someone will always have more. Rather, look at what you have got and who you are, accept and value that. Work toward being a better one than you were last month or last year. 【5】 And you will feel a lot happier with, and about yourself.

A.They see the best in you, and that helps you see the best in yourself.

B.That way you will be pleased with the progress that you are making.

C.The key is to take control by making choices and developing habits that make you happier.

D.You can control how happy you are, since giving always makes you feel happier.

E.If you can't control tomorrow, don't worry about tomorrow.

F.If you aim for perfection all the time, you will never be satisfied or happy.

G.Your relationship with your parents doesn't have to be perfect before you can be happy.
