It’s believed that each one of us has our own fingerprint. But did you know that our fingerprints could show a lot about us?According to The Conversation, fingerprints can show lifestyle and environment, eating habits, possible medical problems and even the job of a person.So how can we work all this out from just a simple fingerprint?Well, a fingerprint is formed when a finger touches a surface.

A fingerprint check may also tell a doctor whether a patient is properly having a medicine. In the treatment of some of the most serious illnesses, having proper medicine is important.In the future, fingerprint science can be used by the police and help doctors keep us in the best possible health.11.What can we learn from Paragraph 1?A.DNA can be used to solve serious crimes.B.Fingerprints may show everything about us.C.We didn’t begin to use fingerprints until 1980s.D.Fingerprints are now the easiest way to solve crimes.12.Fingerprints may not show a person’s ________.A.lifestyle B.looksC.eating habits D.medical problems13.What can make a fingerprint tell a story about us?A.The chemical development.B.A finger touching a surface.C.The fact that it can be seen clearly.D.The things stuck between raised lines.14.According to the passage, doctors may know about patients just through ________.

Or maybe you’ve booked a hotel and found out later that the room was nothing like the advertisement(广告).These days, we have a better chance of stopping these unpleasant surprises.

The idea is very simple. After you go to a restaurant or stay in a hotel, you can post a review with one of your apps. You can say anything you want. If you like a hotel that you stayed in, you can tell people that it was wonderful. If you think that the food in a certain restaurant was bad, then you can tell people not to eat there. Other people can use their app to read your reviews.Plenty of people prefer not to use these review apps. Many of these people think that it’s a waste of time to look through websites and read reviews. These people prefer to go out and decide for themselves whether or not a service is good. However, review apps are getting more and more popular every day. Some apps are for exact services. For example, trip adviser gives attention to travel, and good reader pays attention to books. There are also other larger apps that provide information for just about every service that you can think of. 26.What does the article say about apps?A.You can use apps for many things.B.There are very few good apps.

Every time he walked past the other animals, he would show off his feathers(羽毛)and say, “I am so beautiful. Move out of my way!”The other animals thought Turkey was too proud.

It is something that all humans have, and it tells the body what to do. DNA is the reason that we look like our parents, because we get some of the DNA to make our own.People have been trying to understand the human body for a long time. In 1860, Mr. Mendel discovered why we look similar to other people in our family. It is because of small things called “genes(基因)” in our body. In 1953, two scientists, Watson and Crick, found out that those small parts are real messages. They are written in the DNA with a special language.In 1961, another two scientists found the first “word” that they could understand in that language. It shows how DNA tells the cell(细胞)to build its parts. So far, scientists have found all the words in the DNA map, but we do not understand what they all do. By understanding what just one “word” means, we can help to save people from several illnesses. So the more we understand, the more doctors will be able to do.Most people hope that this will help to make better medicine to help sick people. Other people worry that when we learn more “words” and find out more information, we will use in the wrong way, just to make people more attractive(有吸引力的), or stop sick people getting jobs.46.Who discovered why we look like other people in our family in 1860?A.Crick.B.Watson.C.Mr. Harris.D.Mr, Mendel.47.The two scientists found ________ in 1961.A.all the words in the DNA mapB.small things called “genes” in our bodyC.the first “word” that they could understand in that languageD.the small parts are written in the DNA with a special language48.How can we help sick people if we understand more “words” in the DNA map?

The elephant waved it away with his long ears. Then the fly came again and the elephant waved it away once more.This happened several times. Then the elephant asked the fly, “Why are you so restless and noisy? Why can’t you just stay in one place?”The fly answered, “I am interested in whatever I see, hear or smell. My five senses, and everything that happens around me, pull me here and there and I cannot resist (抵抗) them. What is your secret? How can you stay so calm and still? ”The elephant stopped eating and said, “My five senses do not rule me. I am in control of myself — my senses do not tell me what to do. This helps me stay focused on whatever I do, and so, keep my mind calm and still. Now that I am eating, I am completely enjoying eating. In this way, I can just focus on enjoying my food.”After hearing these words, the fly’s eyes opened wide and a smile appeared on his face. He looked at the elephant and said, “I understand! I will always be restless if I let my senses control me. On the other hand, if I try to use some self-control, my mind will become calm and I’ll be able to stay still.”It is said that the mind is restless and pays attention to whatever is in front of it. But if you can control what you pay attention to, you can control your mind.54.The fly thought he moved around a lot because ________.A.he had nowhere to landB.he couldn’t see things clearlyC.he was interested in everything around himD.his five senses couldn’t work with each other55.According to the elephant, what is the key to staying calm?A.Being in control of one’s senses.B.Enjoying eating.C.Being able to find peace.D.Focusing on many things at the same time.56.Which of the following is TRUE according to the story?A.The fly can resist everything that happens around him.B.The five senses always rule the elephant.C.The fly will be calm if the senses control him.D.The elephant can focus on what he is doing.57.Which of the following can be the best title for this passage?A.Stay Still and Calm B.Focus on More Than One Thing C.Pay Attention to Your Feelings D.Take Control of Your Mind13、(2021·四川眉山)Have you ever imagined the life in space? The following will show you the astronauts’ daily life.● Eating in spaceIf you go camping for more than a week with some friends, you will make sure you haveplenty of foods and keep them properly. At the end of your camping trip, you would deal with your rubbish properly before the ride home.Astronauts almost do the same thing when they go to space. Preparation changes with the food type. Some foods can be eaten in their natural forms, such as chocolate cakes and fruits. Other foods require adding water, such as cheese. Of course, an oven is provided at the space station to heat the food. But there are no fridges, so space food must be kept properly.● Sleeping in spaceAfter a long day at work, nothing is better than a good night’s sleep! Just like on the earth, in space astronauts go to bed at a certain time, then get up and prepare for work again. When going to sleep, they have to attach themselves, so they don’t float (漂浮) around or hit their bodies against something. They usually use sleeping bags located in small crew cabins (乘员舱). Each crew cabin is just big enough for one person. Generally, astronauts have an eight-hour sleep each day when they finish their task.● Doing sports in spaceExercise is an important part of every astronaut’s daily life to prevent muscle loss (肌肉萎缩). Usually, astronauts exercise two hours every day. Lifting 200 pounds on the earth may be a lot of work. But lifting that same object in space would be much easier. That means the things for exercise need to be specially designed, so astronauts can receive the exercise needed.Living in space is not just all work and no play. Astronauts have fun, too. They like to look out the window and play with their food. Fun plays an important role in the quality of their life.58.The writer starts to explain eating in space by ________.A.telling a story B.asking a question C.giving an example D.comparing two facts59.What does the underlined word “attach” in Paragraph 4 mean?A.Tie.B.Hide.C.Catch.D.Carry.60.It is much easier for people ________ in space than on the earth.A.to fall asleep B.to lift heavy things C.to prevent muscle loss D.to eat cold food61.In which part of a newspaper can we read the passage?A.CULTURE.B.SOCIETY.C.SCIENCE.D.HISTORY.14、(2021·四川眉山)Governments around the world are pushing for an end to plastic straws (吸管) and bags. More and more businesses are turning to paper products as a choice. Paper is considered by many to be better than plastic. However, it, too, is harmful to the environment.Firstly, paper bags and straws are made from trees. Trees, as you know, can reduce (减少) carbon dioxide (二氧化碳) levels in the atmosphere. They can slow down climate (气候) change. An increase in the use of paper bags can cause more acts of cutting down trees.Secondly, products made from paper require more energy and water. About 10 percent more energy and four times as much water is used to produce a paper bag than a plastic one. You might say that we can use recycled paper to save that energy and water. This seems to be a good idea. However, it takes even more energy and water to go through the recycling process than to make a brand new paper bag. Products made from recycled paper are also often short-lived.Thirdly, paper products are heavier than plastic ones. That means they require more oilto transport. Seven trucks are needed to transport two million paper bags, while only one truck is needed to transport the same number of plastic bags. The increased weight also leads to a large amount of waste once the bags are thrown away.Paper products are actually a lose-lose for both the environment and businesses. They are more expensive than plastic products. A paper straw costs about 5 to 12 cents, while a plastic one usually costs only about 2 cents.The most environment-friendly solution is to avoid single-use products altogether. Products like glass water bottles and steel straws can be used over and over again. They are much better than either paper products or plastic products. Through increasing the use of these products, you can greatly reduce your throwaway waste and truly make our Earth a greener place!62.What does the underlined word “They” in Paragraph 2 refer to?A.Plastic products.B.Trees.C.Paper products.D.Businesses. 63.Compared with transporting two million plastic bags, transporting two million paper bags requires ________.A.fewer trucks B.six more trucks C.twice as many trucks D.the same number of trucks64.The writer compared the price of a paper straw and that of a plastic straw to show that ________.A.paper products are not a good choice for businessesB.it is difficult for all businesses to turn to paper productsC.most people believe paper products are better than plastic onesD.paper products are as harmful to the environment as plastic ones65.By writing this article, the writer mainly wanted to ________.① compare plastic products with paper ones① correct people’s wrong ideas about paper products① suggest people use reusable products like steel straws① list the advantages and disadvantages of using paper productsA.①①B.①①C.①①D.①①15、(2021·四川达州)In 1987 a small company named Huawei was started in Shenzhen. After more than 30 years of development, the company has now beaten Apple and become the world’s second largest maker of smartphones. It has also become the world’s supplier (供应者) of 5G. In China and even in the world, Huawei is a wonder. Although it started producing mobile phones not many years ago, it has become one of the most famous phone companies.But recently, Huawei faces some difficulties. The US government made a law to stop its sales in America. American officials said Huawei gave information that it collected to the Chinese government. At the same time, the US government planned to stop selling parts and services to Huawei. They believed that Huawei’s business would be hurt this way.“We have never received such a request from the Chinese government and we have never tried to get into other systems to collect information,” Ren Zhengfei, Huawei’s president said. “The law would have little effect on our company. Huawei has enough ability to deal with the problems,” Ren added.In an interview several years ago, Ren Zhengfei said, “I started Huawei with only £4000 at the beginning, but now it has become a 100 billion company. The experience was not as。
