¡¾´ð°¸¡¿Good morning, everyone,

I am Li Hua from Xingguang Middle School. The topic of my speech is ¡°Let¡¯s ride bicycles¡±.

As is known to all, with the improvement of people¡¯s living standards, cars have become a popular means of transport, bringing great convenience to our life. However, they have also caused some problems such as air pollution and traffic jams.

How can we solve the problems then? As far as I¡¯m concerned, riding bicycles is a good solution. For one thing, bicycles don¡¯t need any petrol and they are energy-saving. For another thing, bicycles are environmentally friendly because they won¡¯t give off waste gas. What¡¯s more, riding bicycles is a good way for us to exercise and it is beneficial to our health.

Therefore, let¡¯s take the responsibility to build up a low-carbon city by riding bicycles. Come on and join us!

Thank you!

The British actress, Emma Watson, finally got to bring her childhood hero to life. She played the beautiful Belle in Disney¡¯s new live-action version of its classic animation (¶¯»­Æ¬) Beauty and the Beast. Watson also sang in the film -- the first time she ¡¾1¡¿ (do) so in her career.

However, she doesn't regret it. She told Vanity Fair that she believes the movie says something important that people ¡¾5¡¿ hear.

But ¡¾7¡¿ (build) her own version of Belle, Watson had a hand in shaping the character.

Not content with being a global movie star, Watson also spends time being creative elsewhere. Her house is full of paintings that she created ¡¾9¡¿.

¡¾ÌâÄ¿¡¿ WHAT are scientists? They are often described as gray-haired white-coated dull scholars.

But the world has changed. Young scientists are making their voices heard and releasing their powers on the world stage.

This is also true in China. Rising stars include new materials expert Gong Yongji, university professor Liu Mingzhen, and biologist Wang Ruixue. At the age of 28 in 2018, Wan Ruixue received the 2018 Science & SciLifeLab Prize for Young Scientists. This is a global prize to reward outstanding scientists at an early stage of their careers.

She focuses mainly on biomedicine(ÉúÎïҽѧ)and artificial intelligence(È˹¤ÖÇÄÜ). "Both are cutting-edge(Ç°ÑØ)technologies at an early stage of development," she said.

"So, I think they have great potential to be developed. I think in the study of cutting-edge technologies, China and other leading countries in the world are standing on the same starting line. And in the study of structural biology, China is likely to become the leader."

She felt it was her fate to become a biologist. "I grew interested in the natural world, when I was very young," she said. In 2009, she entered Sun Yat-sen University.

In her third year at the university, she realized that she wanted to do something related to biomedicine. So she emailed China's top biologist Shi Yigong, hoping to join his lab at Tsinghua University.

Shi recognized her talent and welcomed her. Years of efforts at the lab have paid off. Her research on the high-definition 3D structure of spliceosome led to a scientific breakthrough.

Unlike-many of other young scientists who choose to pursue further study abroad, Wan currently has no plan to go overseas.

"The whole ecosystem for scientific research is continually improving in China," she said, adding the country has great science facilities.

¡¾1¡¿What does the underlined word "releasing" in Paragraph 2 mean?

A.Giving out.B.Getting over.

C.Finding out.D.Taking over.

¡¾2¡¿What does Wan Ruixue feel about the study of cutting-edge technologies in China?

A.Anxious.B.Confident.

C.Disappointed.D.Satisfied.

¡¾3¡¿What can we learn about Wang Ruixue's journey of becoming a biologist?

A.Her teacher led her into the field.B.She finds it's easier than she thought.

C.Her contribution has been recognized.D.She thinks it's boring but worth trying.

¡¾4¡¿Which can be the best title of the text?

A.China's Breakthrough in ScienceB.Rising Young Scientists in China

¡¾ÌâÄ¿¡¿To: David Rodgers

From: Mavis Chen

Subject: getting back our old subscribers

Since the marketing meeting yesterday, it occurred to me that we might be ignoring one potentially important source of subscribers. We have focused so intently on how to expand the appeal of our product to groups that have never used it before that I¡¯m afraid we may have overlooked the obvious£» we may have forgotten that there is a whole group of interested people who have used it and stopped for one reason or another.

This target group has particularly good potential because it consists of readers who have demonstrated interest in the subject matter we present. Their interest is not something we have to work to stimulate. I suggest that making a maximum effort to win these readers back will be more effective on a percentage basis than pursuing some of the other groups we¡¯ve identified.

Since these readers quit using our product once, they were most likely dissatisfied with some aspect of our presentation or our pricing. Our new product will be vastly improved over the old version and is priced more competitively. We need to do everything possible to get those points across, perhaps by sending them a free issue and by asking for their opinions on how we might improve it even further. This could be in the form of a very short survey, either included with the free issue or accessible online.

If you think this idea has merit and might be willing to authorize it, let¡¯s discuss it further when you¡¯ve got a few spare minutes. I have a rough draft of the survey questions I could show you.

¡¾1¡¿What kind of product is the writer referring to in the memo?

A.A web-based information service.B.A magazine.

C.A consulting service.D.Computer software.

¡¾2¡¿Why is the writer confident that they can win back their old customers?

A.Their product has no competition.

B.Their product has changed dramatically.

C.They have reduced the price of their product

D.The need for their product has increased.

¡¾3¡¿What does the writer want to do?

A.Start her plan immediately.B.Wait for input from the survey.

C.Get Mr. Rodgers¡¯ approval.D.Present her idea in the next meeting.

¡¾ÌâÄ¿¡¿ No one can change the weather. Nobody can control the weather. But if we read correctly the signs around us, we can tell what the more important changes in the weather will be. This way of telling what the weather will be like on the following day or two is called weather forecasting. For many centuries and in all countries, people have studied the weather and tried to make weather forecasting. Rings around the sun are a sign of coming rain. Many people feel in their bones the coming of wet weather, their joints(¹Ø½Ú) hurt. Some birds fly high if fine weather is coming, but they fly near the ground if rainy or stormy weather is on the way. It is probably because the insects which they are hunting fly low. If you see a rainbow during rainy weather, this is a sign that the weather will become clear and fine. If the stars twinkle clearly at night, then fine weather will continue. If a fog appears in the morning just above a river, then the day will be warm. If the sunset is mostly red in color, then the following day will be fine. If a rainbow appears in the morning, rainy weather will probably come. Most of the above sayings have been made by the people who have used their eyes and brains to make weather forecasting.

¡¾1¡¿People¡¯s joints ache ______.

A.is a sign of coming rainB.without any reason

C.because they are illD.because of the insects

¡¾2¡¿The birds fly high and the stars twinkle clearly is a sign that the weather will ______.

C.become clear and fineD.be cold

C.read correctly the signsD.All of the above
