Why would human beings waste a third of their lives sleeping when they could be doing more important things like looking after their families or working? Some scientists believe sleeping helps recharge the body, while others think it is important for strengthening newly-formed memories. Now, there is new evidence which suggests that the purpose of sleep may be to forget some of the millions of new things we learn each day.

The neurons in the human brain consist of fibers called dendrites(树突). These grow as we learn new things and connect the brain’s cells to each other at contact points called synapses(突触). The larger the dendrites become and the more cells they connect, the more information we store.

In 2018, Giulio Tononi and Chiara Cirelli, both biologists at the University of Wisconsin-Madison, suggested a new idea: The things our brains learn each day result in so many synapses that things start to get a little messy. Sleeping allows us to sort through(整理) the “noise” and dispense all the unnecessary information, leaving behind only the most important memories.

Recently, the university’s research has provided direct evidence to support the theory. The experiment involved analyzing 6,920 synapses in the brain shavings from two groups of mice over a four-year period; one group had been allowed to sleep, while the other had been kept awake and entertained with toys. The researchers discovered that the brain shavings of the sleeping mice had nearly 20 percent fewer synapses than those that had been kept awake and entertained.

It was also evident during the study that the brain does not shave every synapse. 20% of neurons remained unchanged; these were most likely well-established memories. Therefore, although we may be sleeping to forget some of what we’ve learned, the brain “forgets”in a smart way.

Most researchers believe clearing our brains is not the only purpose of sleep. Resting our minds and bodies has also been found to help with other biological functions like strengthening our immunity. Though scientists may never agree on a single reason, they are all sure of one thing－a good night’s rest is essential for our health. So try and spend at least a third of your day sleeping!

This November, I turn 26. This will be my third birthday as a wife. My husband doesn’t like parties nor does he remember the birthdays of his family members, including his own birthday! And he always refuses the idea of celebrating birthdays. For him it is only a waste of money and time! For me, celebrating a birthday is not a big deal as long as somebody remembers my birthday and says “happy birthday” to me, which will make my day brighter. And I’m sure my parents will call me and say these words, but not my husband. In my heart I still hope that he will remember my birthday. Until now, I only remember cebelebrating my birthday twice. The first time was when I turn 12 years old. I treated my close friends to a meal in the school canteen. But I will always remember my 17th birthday. It seemed that nobody in my class talked about my birthday that day. I thought there would be no celebrating so I felt unhappy. But after the bell rang to end the class, my friends threw gifts onto my desk and said, “Happy birthday” And that day became the　 happiest moment I ever experienced.

阅读下面短文，按照要求完成阅读任务。

What will people die of 100 years from now? If you think that is a simple question, you have not been paying attention to the revolution that is taking place in bio-technology. With the help of new medicine, the human body will last a very long time. Death will come mainly from accidents, murder and war. Today’s leading killers, such as heart disease, cancer, and aging itself, will become distant memories.

In discussion of technological changes, the Internet gets most of the attention these days. But the change in medicine can be the real technological event of our times. How long can humans live? Human brains were known to decide the final death. Cells are the basic units of all living things, and until recently, scientists were sure that the life of cells could not go much beyond 120 years because the basic materials of cell, such as those of brain cells, would not last forever. But the upper limits will be broken by new medicine. Sometimes between 2050 and 2100, medicine will have advanced to the point at which every 10 years or so, people will be able to take medicine to repair their organs (The medicine, made up of the basic building materials of life, will build new brain cells, heart cells, and so on—in much the same way our bodies make new skin cells to take the place of old ones).

It is exciting to imagine that the advance in technology may be changing the most basic condition of human existence, but many technical problems still must be cleared up on the way to this wonderful future.

1.What are the present major killers according to the writer? (No more than 10 words)

____________________________________________________________________________.

2.What does the underlined word in the 1st paragraph “revolution” mean? (No more than 5 words)

请阅读下面短文，并按照要求用英语写一篇150词左右的文章。

The University of Cambridge confirmed that it would accept students based on Gaokao test results in a post on the University’s official Weibo account on March 25.

The Gaokao, China’s extremely difficult university entrance exam, is now accepted by a number of overseas universities including the University of New Hampshire, which last year became the first state university in the US to accept Gaokao scores for new admissions, the University of Western Australia and the University of British Columbia in Canada.

Previously, Chinese students would have to take standardized college admission tests, such as the SAT and ACT used in US schools.

The Gaokao is regarded as suitable preparation for Cambridge. The Gaokao scores of successful applicants will vary from province to province and year to year. As a guideline, successful applicants will usually have scores in the top 0.1% of those taking the Gaokao in their province. In addition to the total score, Cambridge Colleges will pay close attention to individual subject scores and scores in the Senior High School Examinations (Xueye Shuiping Kaoshi; previously the Huikao). The Xueye Shuiping Kaoshi alone are not regarded as suitable preparation for Cambridge.

阅读下面摘自China Daily的一则信息，然后按照要求写一篇150词左右的英语短文。

The Ministry of Education said on Monday that starting this spring, a system of recycling textbooks will be established in rural primary and secondary schools, which means some textbooks will be given to students by the schools free of charge at the start of a term and be returned at the end of the school term so that they can be used by other students.

The central government will set up a fund for the purchase of these textbooks, and the students will be required to keep the books in good order for their reuse by others.

It is a heartening move with two major benefits.

First, it will lighten the financial burden on government and families.  Textbook costs account for 53 percent of all the fees primary school students must pay and about 65 percent of those facing middle school students.

Second, using secondhand books is environmentally friendly because of the resources such as trees and energy that are saved. According to industry figures, producing one ton of texbook paper requires 20 trees aged between 20 to 40 years, 100 tons of water, 1.2 tons of coal and other materials and churns out 300 tons of polluted water.

高三英语书面表达简单题查看答案及解析

A 2018 report found that food waste would increase by a third to 2. 1billion tons by 2030. Beyond the cost of the waste itself，thrown-away food generates a gas that contributes to climate change.

Home delivery meal kits(盒)can reduce food waste by more than two-thirds，but suppliers need to switch to reusable packaging to make them environmentally friendly.

Tailor-made meal kits cut waste by providing people with precise amounts of fresh ingredients(烹饪原料)for chosen recipes，meaning leftovers are minimized. But while the　 delivery services score well on reducing food waste，buying the same food ingredients from the supermarket almost always saves energy overall simply because meal kits use so much single-use packaging. The good news is that if people have meals that are tailored for consumption，they won’t overbuy and have less food waste. They fine-tune the amount of food to what they will actually eat.

Meal kits can reduce transport emissions(排放)if people go to the supermarket less　 frequently. If people only go and buy such goods as soap and toilet paper，they may only have to visit once every couple of months. A delivery truck can carry meals for a lot of people in the neighborhood. So dozens of car trips might be replaced with one truck trip.

However，study found that even if delivery meal kits reduced food waste to zero，they would still use up more energy overall than buying the same food from the supermarket unless the energy used for the meal kit packaging was cut by a fifth. The packaging is a killer if it’s single-use and thrown away，which can make all the environmental benefits lost. But if the packaging can be reused，if it’s glass bottles，like in the old days，we can get some benefits.

1.What can we learn about home delivery meal kits?

A.They can cut down on daily expenses.

B.They will totally solve the problem of food waste.

C.They can keep energy consumption to a minimum.

D.They will benefit the environment with reusable packaging.

2.What does the underlined word“fine-tune”in paragraph 3 mean?

A.Attach. B.Adjust.

C.Raise. D.Compare.

3.The author suggests carrying meals with a delivery truck to__________.

A.reduce transport emissions B.save more food

C.shop only in the supermarket D.shorten car trip distances

4.What’s the author’s attitude to meal kits?

A.Supportive. B.Unfavorable.

C.Objective. D.Indifferent.

A daughter complained to her father about her life and how things have been so hard for her.She did not know how she was going to make it and she wanted to give up.She was tired of fighting and struggling. It seemed that just as one problem was solved another arose.

In half an hour he walked over to the stove and turned down the fire.He pulled the carrots out and placed them in the bowl.He pulled the eggs out and placed them in the bowl.Then he ladled（盛）the coffee out and placed it in a cup.Turning to her he asked.“Darling what do you see?”

“Carrots, eggs, and coffee.”she replied.

He brought her closer and asked her to feel the carrots.She did and noted that they were soft.He then asked her to take an egg and break it.After pulling off the shell, she observed the hard-boiled ege. Finally, he asked her to sip the coffee.She smiled, as she tasted its rich aroma（芳香）.

Humbly, she asked.“What does it mean Father?”

He explained.“Each of them faced the same adversity,however each reacted differently.The carrot went in strong, hard.But after going through boiling water, it softened and became weak.The egg was fragile.A thin outer shell protected a liquid center.But after sitting through the boiling water, its inside became hardened.The coffee beans are unique however.After they were in the boiling water, they had changed the water”

Much meaning can be conveyed, clearly with our eyes, sop it is often said that eyes can speak.

Do you have such a kind of experience? In a bus you may loom at a stranger, but not too long. And if he is sensing that he is being stared at, he may feel uncomfortable.

The same in daily life. If you are looked at for more than necessary, you may look at yourself up and down, to see if there is ..If nothing goes wrong, you will fell angry towards others' stare at you that way. Eyes do speak, right?

Looking too long at someone may seem to be rude and aggressive. But things are different when it comes to staring at the opposite sex. If a man glances at a woman for more than 10seconds and refuses to avert his gaze, his intentions are obvious, that is ,he wishes to attract her attention, to make her understand that he is admiring her.

However, the normal eye contact for two people engaged in conversation is that the speaker will only look at  the listener from time to time, in order to make sure that the listener does pay attention to what the former is saying, to tell him that he is attentive.

If a speaker looks at you continuously when speaking, as if he tries to dominate you, you will feel disconcerted. A poor liar usually exposes himself by looking too long at the honest communication, quite the contrary.

In fact, continuous eye contact is confined to lovers only, who will enjoy looking at each other tenderly for a long time, to show affection that words can't express.

Evidently, eye contact should be done according to the relationship between two people and the specific situation.
