2021年威海市第四中学高三英语下学期期中考试试题及答案解析
第一部分阅读（共两节，满分40分）
第一节（共15小题；每小题2分，满分30分）
阅读下列短文，从每题所给的A、B、C、D四个选项中选出最佳选项
A
A medical capsule robot is a small,often pill-sized device that can do planned movement inside the body after being swallowed or surgically inserted. Most models use wireless electronics or magnets or a combination of the two to control the movement of the capsule. Such devices have been equipped with cameras to allow observation and diagnosis, with sensors that “feel,” and even with mechanical needles that administer drugs.
But in practice, Biomechatronics engineer Pietro Valdastri has found that developing capsule models from scratch (从头开始) is costly, time-consuming and requires advanced skills. “The problem was we had to do them from scratch every time,” said Valdastri in an interview. “And other research groups were redeveloping those same modules from scratch, which didn’t make sense.”
Since most of the capsules have the same parts of components: a microprocessor, communication submodules, an energy source, sensors, and actuators (致动器), Valdastri and his team made the modular platform in which the pieceswork in concertand can be interchanged with ease. They also developed a flexible board on which the component parts are snapped in like Legos. The board can be folded to fit the body of the capsule, down to about 14 mm. Additionally, they compiled (编译) a library of components that designers could choose from, enabling hundreds of different combinations. They arranged it all in a free online system. Designers can take the available designs or adapt them to their specific needs.
“Instead of redeveloping all the modules from scratch, people with limited technological experience can use our modules to build their own capsule robots in clinical use and focus on their innovation,” Valdastri said.
Now, the team has designed a capsule equipped with a surgical clip to stop internal bleeding. Researchers at Scotland’s Royal Infirmary of Edinburg have also expressed interest in using the system to make a crawling capsule that takes images of the colon(结肠). One research group, led by professors at the Institute of Digestive Disease of the Chinese University of HongKong, is making a swimming capsule equipped with a camera that pushes itself through the stomach.
One limitation of Valdastri’s system is that it’s only for designing models. Researchers can confirm their hypotheses (假设) and do first design using the platform, but will need to move to a custom approach to develop their capsules further and make them practical for clinical use.
1. According to the passage, Valdastri and his team created the platform to ________.
A. adopt the latest technologies
B. make their robots dream come true
C. help build specialized capsule robots
D. do preciser observation and diagnosis
2. What does the underlined phrase “work in concert” mean in Para.3?
A. Perform live.
B. Run independently.
C. Act in a cooperative way.
D. Carry on step by step.
3. What can be learnt from the passage?
A. Valdastri’s system can’t provide a complete capsule creation.
B. The modular platform is more useful than a custom approach.
C. The capsules can move in human’s body automatically.
D. It costs more to module the capsules on the board.
B
Remember when your mom told you not to eat too many candy bars or sweets because they can cause tooth decay (蛀牙)? However, it turns out that chocolate can be moresalutaryto your teeth than you might expect. Recent studies show that chocolate can effectively fight against tooth decay, as if we need another excuse to eat chocolate.
Chocolate offers protection like fluoride, a main ingredient in most household toothpastes. Not only does chocolate protect our teeth, but it can do so very effectively. Studies show that chocolate has compounds that provide strong protection for teeth. One of the compounds in chocolate, CBH, is shown to protect even more effectively than fluoride.
Tooth decay happens when bacteria work to turn sugar into acids in our mouth. This is why eating foods with high sugar content can lead to more tooth decay. The compounds in chocolate, however, are anti-bacteria and can fight against bacteria in your mouth. The CBH compound in particular also works to strengthen tooth enamel (牙釉质), andprotects against tooth decay.
Does this mean you can cat as much chocolate as you want without worrying about your teeth? It depends on the types of chocolate that you like. The protective effect of chocolate is most effective when you chew on cocoa beans. Of course, this option is not very appealing to; most people. A more tasty option is to choose dark chocolate with little sugar content, ideally no more than 6 to 8 grams per serving. For other types of chocolate
with higher sugar content, the effect will be lessened. However, because of the protective compounds, it is still better for your teeth than other sweets and desserts containing the same amount of sugar.
4. The word “salutary” in paragraph 1 means?
A. Beneficial.
B. Harmful.
C. Familiar.
D. Useless.
5. What can we know about the compound CBH in chocolate?
A. It can help chocolate cure tooth decay.
B. It can effectively stop teeth from decaying.
C. It may protect teeth better than toothpastes do.
D. It may soon replace most household toothpastes.
6. How does chocolate fight tooth decay?
A. By breaking down acids.
B. By building up compounds.
C. By fixing up tooth enamel.
D. By fighting against bacteria.
7. What's the main idea of the text?
A. Chocolate plays the role of toothpaste.
B. Chocolate protects against tooth decay.
C. Chocolate is the best choice for teeth protection.
D. Chocolate is healthier to teeth than other sweets.
C
Please take a few seconds and think of your personal biggest goal. Imagine telling someone you meet today what you’re going to do. Imagine their congratulations and their high image of you. Doesn’t it feel good to say it out loud? Don’t you feel one step closer already? Well, bad news: you should have kept your mouth shut, because that good feeling will make you less likely to do it.
Any time you have a goal, there is some work that needs to be done to achieve it. Ideally, you would not be satisfied until you’d actually done the work. But when you tell someone your goal and he acknowledges(认可) it, psychologists have found it’s called a “social reality”. The mind is kind of tricked into feeling that it’s already done. And then, because you’ve felt that satisfaction, you’re less motivated to do the actual hard work necessary. This goes againstthe traditional wisdom that we should tell our friends our goals, right?
In 1982, Peter Gollwitzer, a Professor of Psychology, wrote a whole book about this. And in 2009, he did some new tests that were published. It goes like this: 163 people across four separate tests—everyone wrote down their personal goal. Then half of them announced their commitment(许诺) to this goal to the room, and half didn’t.
Then everyone was given 45 minutes of work that would directly lead them towards their goal, but they were told that they could stop at any time. Now those who kept their mouths shut worked the entire 45 minutes on average, and when asked afterwards, said they felt they had a long way to go to achieve their goal. But those who had announced it quit after only 33 minutes on average, and when asked afterwards, said that they felt much closer to achieving their goal.
8. What do the words “social reality” in Paragraph 2 mean?
A. Completion of the goal.
B. Necessary hard work.
C. People's acknowledgement.
D. A sense of satisfaction.
9. What does Peter Gollwitzer try to tell us?
A. Writing down the goal is very helpful.
B. Achieving personal goal needs more time.
C. Keeping the goal secret makes people work harder.
D. Making the goal public makes people less satisfied.
10. How did Peter Gollwitzer prove his idea about people’s goal?
A. By giving figures.
B. By giving examples.
C. By making a survey.
D. By making comparison tests.
11. What will probably happen if you tell your friends your goal?
A. You will be more confident.
B. You will not gain satisfaction.
C. You are less likely to realize it.
D. You’ll be much moremotivated.
D
To hear people talk about Internet friendships, you would think it was one giant web of cat-fishing and e-crime. While we all undoubtedly have to take measures to remain safe online, assuming every friendship or connection made on Instagram, Twitter or Facebook is cheating or insincere would be a mistake.
As a woman who works in the creative industry, I have found real joy in seeking out a community I couldn’t find elsewhere, and making some great friends along the way. My first online friendship was on Twitter with my(now) best friend, during the university exam period. We exchanged study notes in dozens of direct messages, set a study date, and haven’t looked back since.
Drawn to each other by similar circumstances, friendships online are similar to offline in that they tend to begin because of shared interest or common ground-maybe they’ve read the post on Instagram. Maybe they have the same taste in food or politics. Or maybe they just love memes too. If online friendships start similar to
friendships offline, they grow in the same way, too. Often through mutual support: apart from calling a friend to congratulate him on that new job, you also re-tweet his jokes and praise his Instagram story.
Despite my positive experiences when I tell people, most are still suspicious. Eyebrows are raised higher when I explain not only have I found a community online but have made friendships with people I meet face-to-face too. Actually, these are just as valid as other friendships, according to behavioural psychologist Jo Hemmings, who says online friendships can be real.
So how do you know if people are there for the real you or just because you’re popular on Instagram? Hemmings has simple rules. She tells me “You have to equally feel comfortable that you’re getting something of each other instead of being used to enable something that isn’t friendship.”
Therefore, if all a “friend” online is asking you to do is to promote their work or personal brand and rarely takes an interest in you, then there may be room to question the basis of the friendship. On that note it is worth remembering that just because someone has a lot of followers, it doesn’t necessarily mean they have lots of friends.
12. What is most people’s attitude towards online friendship?
A. Negative.
B. Positive.
C. Objective.
D. Neutral.
13. Why does the writer share her own experience in paragraph 2?
A. To introduce the background information of the text.
B. To convey the writer’s attitude and give the related example.
C. To prove the likely risk for people to develop friendship online.
D. To remind people of the various benefits of making friends online.
14. How can online and offline friendships be deepened?
A. They should be based on shared interest.
B. They need to have common ground.
C. They require support from each other.
D. They can’t live without social media.
15. According to the author, what’s the golden rule to make friends online?
A. A friend to all is a friend to none.
B. Without confidence there is no friendship.
C. A friend without faults will never be found.
D. Friendship cannot stand always on one side.

How to Forgive Someone
Forgiving someone who has done something wrong and hurt you can be difficult and painful.___16___ While this is natural, holding on to your anger causes you to become more painful.

This is very important, or you will bottle up feelings of anger towards the other person, making true forgiveness impossible.

I was a high school student then, from the low-income family. So I have to support my family. My first one job was to clean the tables in a small restaurant. I still remember going there early and felt anxious about the new world. I worked harder because I was afraid of losing the job. At night, I was sometimes very tired to do my homework. I came to understand that was not easy to earn money, and that knowledges could change my life. But what I learned from the job, in a hard way, was much more important as what I learned from school.

续写的词数150字左右。

We often take for granted the very things that most deserve our gratitude.
Growing up, I wanted to be just like my mom. Kind and caring, she always seemed to make people comfortable in her presence. For years she was a volunteer in our community. I loved going to the local nursing home to help with her until I hit my preteen years. Suddenly, I was too caught up in my adolescent world to worry about helping others.
One particular summer day when I was twelve, Mom came into my room and told me to get up and meet her at the car. I had planned to spend the day at the lake with friends. Why did she have to ruin everything? Eventually, I made my way outside. I imagined the lake water cooling my skin. Annoyed, I climbed into the car and slammed the door shut. I sat in silence, too upset to make a conversation.
“Tasha, would you like to know where we are going?” Mom asked calmly.
“I guess…,” I murmured under my breath.
“Sweetheart, we are going to a children’s shelter, I have been there before and I think it would benefit you,” she explained.
I felt a knot slowly form in my stomach. How was I supposed to help there?
When we reached the shelter, I was rather surprised. It was a large white Victorian home. As we approached the large front porch, wind bells played a calming tune while trees and blossoms welcomed us. Maybe this wasn’t going to be so bad.
Mom rang the doorbell. The door flew open and we were led to the front room, where all of the children were playing. Toys were spread out across the floor. I noticed a baby whose body was scarred with wounds. The majority of the children had noticeable physical scars（伤疤）such as cuts, scratches and burns. What a terrible life they had before they moved here! My heart sank.
As I was looking around, I felt a gentle pull on my shirt.________________________________________________________
I returned to the shelter with Mom several times._____________________________
