In the 1970s, chemist James Lovelock and microbiologist Lynn Margulis developed the Gaia hypothesis（盖亚假说）: all organic and inorganic components on the planet are part of one self-regulating system, working to maintain life on earth. Scientists agree that we need take significant action to control emissions（排放）. But where scientists and popular movements have thus far failed to convince the world to act, it seems that Mother Earth may have succeeded, with the never-before-seen COVID-19.

COVID-19 is estimated to have reduced carbon dioxide emission in China by a quarter. It caused factories to shut down, and slowed construction activities. Recent analysis shows a 70 percent drop in flights in February compared with January. And even getting into a car and going to a restaurant, shopping mall, or concert poses a risk of infection, which means that many people are choosing to stay at home and are consuming less, resulting in a significant reduction of their carbon footprints.

Of course, China and the rest of the world will hope to restart normal production and consumption as soon as the virus is under control. However, some positive measures have already been taken as a result of COVID-19. As the virus is thought to originate from wildlife, Chinese authorities are revising laws and regulations regarding the country's massive wildlife trade in order to prevent future epidemics（流行病）—a win for biodiversity.

The deaths of thousands of people worldwide should also serve as a lasting reminder of the fragility of life. We humans frequently ignore or repress uncomfortable thoughts of death and extinction. We would rather get on with our lives as usual, thinking everything will somehow work out in the end. Only in the face of suffering and death are we forced to view the bigger, longer-term perspective—and this is what is needed in order to react appropriately to climate change. COVID-19 has sent alarm bells ringing throughout the world.

Ronald Hoffman born in 1937 is Polish-born American organic chemist and Nobel laureate(桂冠). As a theoretical chemist, Hoffmann studied energy levels in chemical bonds during chemical reactions. He put computers to use to solve his problems and, despite the complexity of his research, was able to explain his theories and discoveries to the non-specialist. For his work he was awarded the 1981 Nobel Prize in chemistry, which he shared with Fukui Kenichi.

Born in Poland, Hoffmann settled in New York City as a child and became a United States citizen. He received his undergraduate degree in premedical studies from Columbia College in 1958. He attended Harvard University, where he received his PhD. degree in chemical physics in 1962. He joined the faculty of Cornell University in the mid-1960s and remained there throughout his career.

Hoffmann and Nobel laureate chemist Robert Burns Woodward developed rules, based on quantum mechanics, to determine how energy levels in atomic electron orbits influence how a chemical reaction takes place. These simple rules, known as the Woodward-Hoffmann rules, allowed chemists to predict reaction results and was quickly accepted and put to use in a wide variety of situations.

Hoffmann later turned his research to a variety of problems related to discovering the molecular structure of inorganic and organometallic compounds. Hoffmann is also known for what is called the Isolobal Analogy, which is yet another discovery linking all areas of chemistry. It is useful in predicting the behavior of new molecules based on the orbit structure of the components used to form them.

Aided by computers, Hoffmann was able to generate a vast amount of data to support his ideas. Unlike the scientific papers of many chemists, Hoffmann's publications contain little raw data but instead are filled with diagrams and pictures to explain his results. His drawings of shaded balloons to indicate eigenvectors, a unit used in mathematics, are now the accepted scientific notation for illustrating this value.

1.What can be inferred from the above passage about Hoffman?

A. He left his homeland when he got the Nobel Prize.

B. He went to the United States to gain his Nobel Prize.

C. He might find the Unites States a better place to learn chemistry.

D. His family may have settled in the United States.

2.How did Hoffman make his research popular?

A. He applied some computer skills to help explain his ideas.

B. He established a special computer system to help.

C. He drew some forms explaining his ideas.

D. He did series of experiments to prove his ideas.

3.The underlined word “generate” in this passage might most probably mean “______”.

A. bring in　　　　 B. break down

B. move away　　　　 D. keep secret

4.Why was Ronald Hoffman awarded the 1981 Nobel Prize for chemistry?

A. He established rules to predict chemical reactions .

B. He succeeded applying computer science to chemistry research.

C. He shared what he had achieved with another scientist named Fukui Kenichi.

D. He succeeded in both chemistry and computer researches.

Today's parents miss the golden age that their own mothers enjoyed in the 1970s and 1980s, researchers found.

Mothers have less time to themselves and feel under greater pressure to juggle work and family life than the previous generation. As a result, 88 per cent said they felt guilty about the lack of time they spent with their children.

The survey of 1,000 mothers also found that more than a third said they had less time to themselves than their mothers did — just three hours a week or 26 minutes a day.

And 64 percent said this was because they felt they 'had' to go out to work, while nearly a third (29 per cent) said they were under constant pressure to be the 'perfect mother', the report found.

Other findings showed social network and parenting website were important in proving help and support among female communities

Kate Fox, of the Social Issues Research Centre, which conducted the survey for Procter & Gamble, said: "With increasing pressure on mothers to work a 'double shift' — to be the perfect mother as well as a wage-earner — support networks are more important than ever."

It comes as a separate report examining childcare in the leading industrialized nations found that working mothers in Britain spend just 81 minutes a day caring for their children as a "primary activity".

Critics say the pressure on women to work long hours, and leave their children in the hands of nurseries or child minders, is putting the well-being of their children at risk.

The study also reveals that, despite the fact that more and more modern mothers go out to work, the burden of childcare still falls on them — even if their husband is not in work.

A father who is not in work tends to spend just 63 minutes a day looking after his child — 18 minutes less than a mother who goes out to work.

Working fathers spare less than three quarters of an hour with their children.

1.What is the main idea of the passage?

A. More and more modern mothers go out to work to support the families.

B. Today's parents would rather leave their children in the hands of nurseries.

C. Today's parents have less time to take care of their children.

D. To keep the balance of work and family is not an easy thing.

2.What does the underlined word "juggle" in Paragraph 2 probably mean?

A. keep objects in the air

B. do many things at once

C. change things

D. organize spending

3.According to Kate Fox, ________.

A. people should learn to relax by using the network

B. network plays an important role in society

C. mothers should make use of the network to gain support

D. it is impossible for woman to become the "double shift"

4.Today's mothers lack the time to company their children mainly because ________.

A. they have no choice but go to work

B. they are under constant pressure

C. they want to be "the perfect mother"

D. they have less time to themselves

5. Which of the following statements is True?

A. Mothers usually spend three hours looking after their children a day.

B. Since more and more modern mothers go out to work, the burden of childcare falls on fathers.

John was part of my childhood growing up in the 1970s and a link to sunny, fun-filled days spent on the beach at Bangor in Northern Ireland where we went for our summer holidays. To many, he was a mystery. Every afternoon John would wander to the end of the pier (码头) where he fed the seagulls and delighted in the sound of their excited cries as they flew around his head.

Often I asked my family questions regarding John. Eventually I gave up as no one could tell me anything about him. As I grew up, my visits to the beach became less frequent, and my memories of John buried in a child's imagination.

Last year memories came flooding back as I walked along the coastline, where I noticed a lady feeding the seagulls on the pier, and I decided to introduce myself. Then I came to know that the lady was John's daughter, and after John left this world she carried out the ritual, which had held such importance for her father.

In some strange way I felt we shared a bond, each needing to remember. In return, Lucy told me of John's life, his days in the British Navy during World War I and how he almost lost hope when his ship was attacked by a German U-boat in the North Sea and he found himself in a lifeboat with five others.

Close to death, he thought he heard the sound of wings. He put up his hands, only to catch a seagull that had landed on the side of the boat. The seagull saved the lives of the six men as it was used to catch fish, which kept them alive until they reach land. This period of John's life was one he never talked about. But the ritual he first performed as a young man remained a part of him until he died.

Now I visit Lucy as often as I can, just to chat or very often walk along the beach to the pier end. We enjoy the comfortable silence, each lost in special memories.

1.Seeing John feeding the seagulls, the author might feel ______.

A.proud B.worried

C.curious D.guilty

2.The underlined word ''ritual" in the third paragraph can be replaced by ______.

A.law B.tradition

C.interest D.procedure

3.We can infer from the text that John ______.

A.once served in both World Wars B.was a man with a grateful heart

C.spent his childhood in Bangor D.joined the navy in the 1970s

4.What does the author mainly tell us in the text?

A.Her thanks to a seagull that saved her life.

B.The story of how she made friends with a lady.

C.Her childhood spent on the beach at Bangor.

D.Her memories of a man who fed seagulls.

Old Mrs. Lynn was working in the cottage, hanging the washed clothes on the line. What she wasn’t aware was that some children were hiding in a nearby tree watching her every move. They were sure that she was a witch and wanted to find the evidence.

They watched nervously as she took a broomstick to sweep the dirt from her stone steps. But much to their disappointment, she didn’t get on the broomstick and fly off. The old lady only looked up when her hen began to make sounds loudly — signaling that she had laid an egg in the nest on the top of the haystack. (干草堆).

The old lady put aside her broomstick and walked to the haystack, followed by Michael, a black cat she had rescued from a fox trap. With only three legs, it was hard for Michael to keep up with his mistress. The cat was proof for the children that only a witch would own a black cat with three legs! Accidentally, she tripped and crashed to the ground. The children were in horror.

“Should we go and help her?” asked Mia.

“What if it’s a trick?” replied Patrick. “She probably knows we’re here. Witches know things like that!”

After thinking for a while, Julia said, “Anyway, we should go and check whether she is all right.”

Approaching prudently, they could see a wound on the old lady’s forehead. She had knocked her head on a stone and was unconscious.

“Go and get Dad,” Mia yelled to her brothers. “Tell him about the accident.”

Later, in the hospital, the old lady smiled her thanks. “I was so lucky that you lovely children happened to be passing when I fell. I must have yelled quite loudly.” The children exchanged guilty glances, but were very pleased that she was not a witch after all!

1.Mrs. Lynn stopped sweeping when ________.
