【題目】 "When I was 16 years old, I was diving in Greece, but I was disappointed because I saw more plastic bags than fish.” These are the words of Boyan Slat, an engineer who designed the world's first ocean plastic cleanup system.

Every year, more than 8 million tons of plastics end up in our oceans, according to the UN Environment Programme. It is predicted that the weight of ocean plastics will match the weight of all the fish in our oceans by 2050. To prevent this from happening, in 2013 Slat created the Ocean Cleanup, an environmental nongovernmental organization, and put his plan for an ocean cleanup device into action.

After years of research and development in the Netherlands, a device called System 001/B successfully started gathering plastics on October 2, 2019. The device uses a 600-meter-long C-shaped tube to gather all the floating rubbish. Unlike other cleanup methods, the system floats freely according to the direction of the waves, which allows waste to flow into and stay within the device. A sea anchor is attached to either end. This slows down the system as it floats through the water and allows the faster-moving rubbish, carried by the waves, to flow into its mouth. System 001/B can also collect waste below the surface using a 3-meter-deep skirt（擋板）attached to the end. After being gathered, the trash will be dragged back to shore by boat and recycled.

Right now, the system operates in the Great Pacific Garbage Patch, an area that is 3 times the size of France. Once operational, the Ocean Cleanup expects a full fleet to be able to clear 50% of the Great Pacific Garbage Patch in 5 years.

"It remains to be seen whether this dream will become a reality, but it is undeniable that humanity must work together to reduce our plastic use and repair the damage our waste has caused," Slat said. "We are starting to see a young generation that gets it and is excited about a sustainable （可持續(xù)的）future, but the question still comes down to: Are we going fast enough, and how much damage will have been done before we get there?"

【1】The underlined word “match” in Paragraph 2 probably means “_________”.

A.compareB.equal

C.measureD.cover

【2】Why did Boyan Slat create the Ocean Cleanup?

A.To collect ocean plastic waste.

B.To help to invent System 001/B.

C.To protect the living environment of fish.

D.To do research on the ocean environment.

【3】What can we know about System 001/B?

A.It can collect and recycle garbage at the same time.

B.It can only gather ocean waste which floats on the water.

C.It aims to clear up the Great Pacific Garbage Patch in five years.

D.It is an ocean-cleaning device which has already been put to use.

【4】What does Slat want to tell us according to the last paragraph?

A.Young generations care less about the environment.

B.The future ecology of the oceans is deeply worrying.

C.People should work hard to decrease plastic pollution.

D.It's quite difficult to repair the damage to the environment.

【題目】 Recently, a new study suggests that staying positive through the cold season could be the best defense(抵御) against getting sick.

In an experiment that exposed（暴露）healthy volunteers to a cold of flu virus, researchers found that people with a generally sunny emotion were less likely to fall ill. The findings, published in the journal “Psychosomatic Medicine”, build on evidence that a “positive emotional style” can help defend the common cold and other illnesses.

“People with a positive emotional style may have different immune responses to the virus,” explained Dr Sheldom Cohen of Carnegie Mellon University in Pittsburgh. And when they do get a cold, they may experience their illness as less serious.

Cohen and his colleagues had found in a previous study that happier people seemed less susceptible(易受影響的) to catching a cold, but some questions remained as to whether the emotional quality itself had the effect.

For the new study, the researchers had 193 healthy adults complete standard measures of personality qualities, physical health and “emotional style”.

Those who tended to be happy, energetic and easy-going were judged as having a positive emotional style, while those who were often unhappy and tense had a negative style.

Afterwards, the researchers gave them nose drops containing either a cold virus or a particular flu virus that causes flu-like symptoms. Over the next six days the volunteers reported on any aches, pains, sneeze they had. Cohen and his colleagues found that positive emotions really have the big effect of fighting virus.

【1】The results of the experiments by researchers suggest that _______.

A.people in excellent spirits are less likely to fall ill.

B.the emotional quality itself has the greatest effect of fighting virus

C.people with a positive emotional style seemed more likely to get ill

D.positive emotional people and negative people response similarly to the virus

【2】Dr Sheldom Cohen made studies and reached his conclusion by _______.

A.comparing the experimental results of different groups

B.looking into the forms completed by the volunteers

C.collecting data among people with a cold

D.observing the volunteers’ symptoms

【3】According to the passage, what quality should we develop to fight virus?

A.Clever.B.Hard-working.

C.Optimistic.D.Friendly.

【4】We can conclude from the passage that _______.

A.positive life can lead to success in one’s career

B.physical health is more important than mental health

C.the happier we are, the less likely we will be to fall ill

D.the more we are together, the happier we will be

Last week, I attended a lecture by a teacher in his thirty. He was energetic and confidence. He spoke very fast and I could understand that he said. He mainly focused at how to learn the English well. In addition, he showed us how to write neatly, letter by letter. He kept telling us, "Slow down!" “Trusting yourself" - Write carefully!". To be honest, I never thought much of writing until today, when my heart touched. At the end of the lecture, all the people present break into cheers. The lecture was so interesting that I benefited a lot from them.
