Since May 12, a computer virus named WannaCry has infected (感染) more than 300,000computers in over 150 countries, according to Reuters.

Wannacry is spread by using a weakness in Microsoft's Windows operating system. Once the virus gets into the computer, it locks all the papers and asks the user for money to unlock them. At first, it asks for $300, but if the user doesn't send the money in 72 hours, the price doubled. Papers are locked forever if the user doesn't pay in seven days.

The virus has brought bad results. For example, in the UK, the virus left the country’sNational Health Service in a mess. Some hospitals had to cancel patient appointments(预约), reported The Telegraph. In China, the virus has hit thousands of computers, according to Qihoo360. One of the most hard-hit groups in China were university users. Many students' graduation papers were locked. They felt nervous and frightened. Also many gas stations were seriously hit, and the payment system didn’t work.

WanaCry is the latest example of the cyber security(网络安全) problem. Matthew Hickey, who set up the security company Hacker House, said, "The attack is not surprising. It shows that many organizations do not use updates(更新) fast enough. According to a survey, nearly half of the people said, “We are not satisfied with the way software updates work.”

As China Daily wrote, “We can’t completely protect our computers against these kinds of viruses, as this cat and mouse game will continue forever. The best choice for most users is to take care online and always install(安装)software updates.”

1.What is WannaCry?

A.A video game. B.A computer software. C.A computer virus. D.A TV programme.

2.If your papers are locked by Wannacry, how much do you need to pay if you don’t send the money in 72 hours?

A.$150. B.$300. C.$600. D.$900.

3.According to the passage, the writer shows the bad results by ________.

A.giving reasons B.giving examples C.comparing computers D.comparing numbers

4.From the last two paragraphs, we can know that________.

A.Matthew Hickey thinks the attack on computers is very surprising

B.all the people are pleased with the way software updates work

C.the computers can be completely protected against these viruses

D.we should take care online and update software fast enough

I'm a virus (病毒) for the common cold. It has been a long time since I infected (感染) humans last time. Today I tried to infect a boy in a primary school all day.

His name is Sam. I waited on his desktop, and when he touched the desk I jumped on his finger. Unluckily, Sam didn't touch his eyes, mouth or nose. Then, right after class, he washed his hands. Now I'm full of soap and sitting in a sink!

Tuesday, January 22nd

This morning I jumped into the nose of Sam's best friend, Bill. Unluckily, the mucus (粘液) in his nose caught me. I thought it was over for me, when suddenly Bill sneezed while he was talking to Sam.

I knew that would send me right into Sam's face! However, Sam quickly gave Bill a tissue, and Bill sneezed into that instead! Infecting people is harder than I imagined.

Wednesday, January 23rd

I'm feeling very unhappy today. Some scientists caught my friend Harry and put him under a microscope. Harry is a flu virus and he's a dangerous little guy. Besides, Sam at all his vegetables today. He's exercising, and he's getting eight hours of sleep every night. His body is too strong for me!

Thursday, January 24th

I tried to infect Sam again today, but he washed his hands five times and never touched his face! He also gave tissues to every student in his class who was sneezing. It's impossible to give him a cold! So I have to give up and I'm moving to another school.

A.easy B.lucky C.dangerous D.difficult

A new Chinese coronavirus (冠状病毒), a cousin of the SARS virus, has infected more than 40,000people since the outbreak (爆发) began in Huanan Seafood Market, Wuhan, China, in December. At first, we knew little about this virus. With more researches going on, we get to learn more about it.

Coronaviruses are a large group of viruses that are common among animals. In rare cases, they are what scientists call zoonotic (人畜共患病), meaning they can be transmitted from animals to humans, according to the US Centers for Disease Control and Prevention. It is believed that the novel coronavirus spreads from human contact with animals. Bats are widely believed to be carriers of the latest strain of the disease.

Chinese researchers said on Friday that the endangered pangolin (穿山甲) may be the intermediate host between bats and humans.

The viruses can make people sick, usually with a mild(轻度) to moderate(中度) upper respiratory tract illness(上呼吸道疾病), similar to a common cold, including a runny nose, cough, sore throat, possibly a headache and maybe a fever, which can last for a couple of days. For those with a weakened immune system, the elderly and the very young, there's a chance the virus could cause deadly diseases.

What's horrible about this virus is that once a human is infected, he/she becomes a carrier of the virus and spreads it to more people by coughing, sneezing or even handshaking. The virus can also be transmitted (传播) by touching something an infected person has touched and then touching your mouth, nose or eyes. Doctors and nurses may also catch the disease when taking care of the patients, so they are required to wear strict protective clothes.

Unfortunately, there are no disease-specific treatments for the disease at this stage, which makes the outbreak a challenging one to control. Besides, since we live in an interconnected world, where the situation in one country can affect the whole world, the influences of the novel coronavirus are huge-damaging trade relations, affecting foreign visitors and weakening the entire country.

To fight against the disease, as individuals, we should strictly follow the requirements of the government to stay at home and help to prevent the spread of the disease. In terms of the government, a strong health care system can surely help decrease the risk of health attack and lessen the impact of the disease.

1.How many people have been affected since the outbreak of the new Chinese coronavirus?

2.Where does the novel coronavirus come from according to the researchers?

3.What symptoms (症状) may people have when they are affected?

4.Why are doctors and nurses required to wear strict protective clothes?

5.What is the main idea of the last paragraph?
