【题目】 Since the end of 2019, a terrible disease has been spreading all over the world. It’s caused by a virus that has not been found before in humans. 1.

What are the symptoms(症状)?

The virus is from a family called the corona viruses. The symptoms of this illness are pretty ordinary on the face of it: it’s dry cough, fever and then breathing problems. 2. However, as for the more severe cases, people have gone on to develop viral(病毒性的) pneumonia, and all the deaths have been among those people.

Who does this virus attack?

As we can see, older people are ending up in hospital with the virus. Most of the affected people are usually over 40 years old. 3. Basically their immune(免疫) systems are not very strong, and they’re going to find it very hard to fight off a virus.

4.

We’ve only just discovered that the new corona virus is actually spread from one person to another. It was hoped at first actually that it just came from animals as all corona viruses do. 5.

A.It seems quite mild(温和的)in lots of people.

B.How is this virus spread?

C.So the disease is called a "novel" or new virus.

D.People affected by viral pneumonia will die.

E.Signs of the virus may appear between 2 and 14 days after being near someone who is affected.

F.Those who have died tend actually to have other diseases already.

G.Now it has been confirmed that it is actually passed from one human being to another, however.

【解析】

这是一篇说明文。文章描述了新冠状病毒的症状,病毒的攻击方式,病毒的传播方式等。

1上一句提到“它是由一种以前在人类身上没有发现的病毒引起的”。承接上文,构成因果关系,C选项“所以这种疾病被称为“新病毒””。切题。故选C项。

2上一句提到“这种病的症状表面上很普通:干咳,发烧,然后是呼吸问题”。承接上文,A选项“在许多人看来,这种疾病似乎相当轻微。 ”A选项中的it 指代上一句的“illness”,mild(轻微的)和前句的ordinary相契合。切题。故选A项。

3划线后一句提到“基本上他们的免疫系统并不是很强他们会发现很难抵抗病毒”。承接下文构成因果关系。F选项“那些已经死亡的人实际上往往已经患有其他疾病”切题。死亡的原因是因为患有其他疾病,导致免疫系统偏弱。故选F项。

4根据下文We’ve only just discovered that the new corona virus is actually spread from one person to another. It was hoped at first actually that it just came from animals as all corona viruses do.可知,我们刚刚发现,新的冠状病毒实际上是从一个人传播到另一个人。起初,人们希望它实际上只是来自动物,就像所有的冠状病毒一样。因此推断本段讲述病毒的传播方式和传播途径。故B选项“病毒是如何传播的”。统领整段,切题。故选B项。

5上一句提到“起初人们希望它只是像所有冠状病毒一样来自动物”。承接下文构成转折。G选项“然而,现在已经证实它实际上是从一个人传给另一个人的”。G选项中的Now 和前句的at first 构成对比。且整句和这一段的主题相呼应。故选G项。

【题目】How Plants Branch Out to Access Water

New research has discovered how plant roots sense the availability of water in soil and then adapt (适应)their shape to acquire water. The discovery could enable crops to be raised which are more adaptive to changes in climate conditions, such as the absence of water, and help ensure food safety in the future.

These findings, published in the journal Science, describe a new mechanism(机制) discovered by cooperating teams at the universities of Nottingham and Durham.

Roots are very important for plants to acquire water and nutrients(营养)from the soil. Water is necessary to plant growth , yet changing climatic conditions makes acquiring water from soil even more challenging. Plants are able to adapt to different soil moisture(湿润)conditions by changing their roots.

The researchers discovered that plant roots lacking a branching master gene were no longer able to branch out. They found that when roots have access to moisture, the certain gene remains active and promotes root branching, but when put in air, the gene is in activated, preventing root branching. The research has identified the certain protein which can inactivate root branching.

Professor Sadanandom explained: "This is hugely exciting as it opens up the possibility for us to help develop plants that could continue to branch roots even in challenging conditions such as the absence of water.'

Professor Bennett concluded: "Water is the key to plant growth, development and their survival. By studying how plant roots change their branching in response(回应)to water availability, we have uncovered a new mechanism. This opens the way to develop new crops better adapted to climate change and to help deliver global food safety."

It is absolutely imperative to ensure food safety worldwide. Crop production must double by 2050 to keep pace with global population growth. This target is even more challenging considering the effect of climate change on water availability. In this case, developing crops with better ability to acquire water would provide a solution.

1The findings of the research may have a positive effect on several global issues EXCEPT

A.ensuring food safetyB.preserving the agriculture

C.solving the absence of waterD.increasing crop production

2With the help of the findings, plants may be able to ________.

A.take in more nutrientsB.change inactivated roots

C.grow in challenging conditionsD.branch out without a special gene.

3Which of the following best explains “imperative" in the last paragraph?

A.effective.B.hopeful.

C.impractical.D.urgent.

4What is the new mechanism mentioned by Professor Bennett?

A.How a branching master gene responds to a particular nutrient.

B.How plant roots change their shape according to the soil moisture.

C.Why plants have different abilities to adapt to soil moisture conditions.

D.How the certain protein in activates root branching when accessible to water.

【题目】 Some years ago, Michel-Andre found himself staring at the body of a dead whale on a beach in the Canary Islands. It was obvious that the animal had been struck violently by a ship——but why? Only later, after surveying the whales which lived in the area and measuring the increase of sound pollution from ships did it become clear that there was a link.

The whales had become desensitised to the noise of approaching boats and were being struck by them, often seriously. “We never thought that this could be something that could kill,” recalls (回忆) Andre, who is the director of the Laboratory of Applied Bioacoustics at the Technical University of Catalonia, Barcelona.

Andre has spent 20 years developing an advanced system to better understand why incidents like this happen. His underwater microphones have exposed a world of deafening sound and animal communication never observed with such clarity(清晰) before.

It was not an easy task. Sound waves don't travel through water in the uniform, predictable way they do through the air. Instead, the temperature, salinity (盐度) and, flow of water have great effects on their path.

What can be done? One solution is to change shipping routes to courses where ships are statistically less likely to meet animals. It’s also possible to slow ships down to 18km/h or less, which is less likely to seriously injure a whale.

As for dealing with the root cause of the problem, the UN’s International Maritime Organisation has already published guidelines on how to quieten ships, but it will be a while before the effects of such changes might be observed.

“The ocean is not our world,” comments Andre. But it is ours to look after. And thanks to his work, we can better understand the effects of subsea sound pollution.

1What does the underlined word “desensitised” in Paragraph 2 mean?

A.Stubborn.B.Flexible.C.Dull.D.Friendly.

2What’s one way to solve the problem according to the text?

A.To lower the speed of ships.

B.To reduce the number of ships.

C.To set up preserves under the sea.

D.To give the injured animals timely treatment.

3What is the author’s attitude towards what Michel Andre has done?

A.Doubtful.B.Disapproving.C.Positive.D.Uncaring.

4What is the text mainly about?

A.A great expert.B.Noise in the sea.

C.Animals in the sea.D.Sea exploration technology.

【题目】 To shoot a scene of people eating food, you need two different perspectives (角度). To record a bus journey to school, you need three quick cuts. To complete this short, morning rush-hour video blog – or “vlog” – you need four pieces of music. 1

With more than 90 million vlogs available online, and 2,000 posted every hour on the YouTube video-sharing site, CBS News says they are mainstream with people born after 1995.

2 More young Chinese people have become inspired to grab a camera and recount the details of their day on Sina Weibo, Bilibili or WeChat Moments.

“The most important thing about vlogging is to tell a good story. Other visual effects are auxiliary (辅助的),” wrote US vlogger Casey Neista, who has almost 10 million subscribers on YouTube.

Chinese vlogger Wang Xiaoguang is an example of a good storyteller. In one of his popular vlog posts, Wang tells the story of traveling to Japan. While there, he took a ride in the wrong direction and got lost. Worse, he forgot to bring a phone charger. 3

Another key aspect of vlogs is that the content is based on everyday life, according to Ouyang Nana, 18, a young Chinese musician. She documents her life at Berklee College of Music. Ordinary as vlogs are, as many as 15 million fans share her wows and woes (喜怒哀乐) on a daily basis.

4 Peng Yixuan, a news reporter with China Daily, recorded her first experience attending and reporting on the two sessions in March of this year. With a relaxed, chatty and personal approach, she presented the conferences, “bringing more warmth” to the grand political event, according to People’s Daily.

There are popular vlogs for beauty, gaming, fashion, food and travel. Vloggers are learning new ways to experience the thrill of them. 5 Then what are you waiting for? Grab a camera!

A.They come from all walks of life.

B.However, he didn’t take the number of his hotel.

C.Vlogging has taken China by storm over the past year.

D.Some other popular vloggers choose to show their careers.

E.Vlogs pave the way for future advertising and sales campaigns.

F.Luckily he was able to borrow money from a stranger and escape trouble.

G.Vloggers have these techniques in mind as they film their daily activities.

With all these, I observed something of8public health miracle: Not only did no child get SARS, but it seemed no student was infected9anything at all for months on end.

【题目】Directions: After reading the passage below, fill in the blanks to make the passages coherent and granunatically correct. For the blanks with a given word, fill in each blank with the proper form of the given word; for the other blanks, use one word that best fits each blank.

Different background shouldn’t mean less education. Fifty years ago, in a primary school classroom, two boys aged 11 took an examination called the 11-plus, 1would make decisions about the rest of their lives. Paul passed and went to a “grammar school”. Baz failed the examination and went to a “secondary modern school”. They did not see each other again for years.

Many grammar schools 2(establish) hundreds of years ago to teach the Latin language to children who were not from rich families. They encouraged students to study 3they were 18 and then to go to university. Secondary modern school students left at 16, usually with fewer qualifications than grammar school students. Baz says the secondary modem school had 4(few)resources and the quality of teaching was not as good.

Things have changed. In the 1960s and the 1970s “comprehensive schools” were created. Today, 90 percent children aged 11 to 16 from the same area to the same school without 5(take) any entry examination.

The British often disagrees about the best way 6(educate) their children. Many people say that comprehensive schools help more children to succeed because they provide everybody 7similar opportunities in a fairer way. Another view, though, is that more intelligent children, especially 8from poor homes are better supported at grammar schools. Now, the government plans to open new grammar schools 9almost two million children will go to the same type of school that Paul attended.

And Paul and Baz? Aged 60, they met again and compared 10had happened to them. After university, Paul qualified as a teacher. Baz went to work in a factory at 16 and later became an engineer. In fact, Baz had a much higher salary than Paul--so perhaps life is fair after all.
