三、阅读理解（共10小题；每小题2分，满分20分）
A
It might be fun to use your smartphone, but be careful. Too much screen time may be harmful to your health.
First, it is bad for your eyes. A researcher called Sarah Hinkley says the problem comes from the blue light that the screen gives out. Looking at a smartphone for a long time can cause eye strain(劳损), headaches and dry eyes. So it is a good idea to take a break every 15 minutes when you are working at a computer or using a smartphone.
Second, screen use can do harm to children's brains. A new study shows that using screens too much can affect(影响) how children's brains grow. If children use screens for more than one hour a day, they might have lower levels of white matter in their brains. White matter is a key to the development of language and reading skills. So it is wise to cut down the time of children using all kinds of screens.
Third, using screens too much will affect your sleep. According to a study, about 95% of the people between the ages of 13 and 64 use electronics before bed, especially the young people under 20. Doctors say that the light from those electronics at night may make you excited before you go to bed. Then ifs hard for you to get enough sleep. So you'd better turn off smartphones, TVs, and all other screens an hour before your bedtime.
To keep healthy, doctors and researchers strongly advise that you shouldn't use screens for long hours.
26. The blue light from your screens can cause _____.
A. eye strain B. headaches C. dry eyes D. all of the above
27. According to the passage, you can't sleep well because you _____.
A. take a break every 15 minutes
B. have lower levels of white matter
C. use screens too much before bed
D. are the people from 13 to 64
28. Which of the following is NOT true according to the passage
A. Using smartphones for long hours does harm to your eyes.
B. A lot of screen time affects children's brain growth.
C. The light from electronics at night may make you excited.
D. People of all ages mustn't use electronics.
29. You may read the passage in _____.
A. a science magazine B. a travel diary
C. a guide book D. a novel
30. What is the main idea of the passage
A. The ways to keep healthy.
B. The harm of using screens too much.
C. The ways to use screens.
D. The advantages of using screens.

Are you afraid of going to the dentist If so, you're not alone.
These fears could just be in our heads, however. According to a recent survey by Martin Tickle, a professor at Manchester University in the UK, the pain isn't felt most of the time in dental surgeries (牙科手术). In fact, among the 451 interviewed patients, 75% reported no pain at all during their visits, including situations when they had their teeth pulled out.
Could it be the sound of the drill (钻头) then
"I found that the sound of drilling can evoke deep worry in dental patients. Actually they don't have any pain," Hiroyuki Karibe, a scientist at Nippon Dental University in Tokyo, told the Guardian.
To find the reason why a drill might bring on a racing heart, Karibe divided the volunteers into low-fear and high-fear groups based on how much they feared a trip to the dentist. Volunteers were played the sound of a drill while their brain activities were watched by a machine.
What Karibe found in the low-fear group was increased activity in the areas of the brain relative to auditory processing (听觉处理), which means, for these people, the sound of dental drills is no different from other sounds.
In the high-fear group, however, the brain area that was activated (激活) was different. It was the area that carries out a number of duties, including learning, feelings and, most importantly, memory. This means that these volunteers not only heard the sound, but they remembered it — they made connections between the sound of a drill and the worry it produced in the past, causing their worry to return.
Understanding how brains reply to the sounds of dentists' drills could help scientists find ways to make patients more relaxed, according to Karibe, because patients who worry about going to the dentist might keep putting off their visits. But the best way is to keep your teeth healthy.
31. How does the writer explain that the pain isn't felt most of the time in dental surgeries
A. By showing facts with numbers. B. By asking questions one by one.
C. By giving examples group by group. D. By comparing results of patients.
32. According to the fourth paragraph, what does the word "evoke" mean in Chinese
A. 减轻 B. 引起 C. 显示 D. 阻止
33. How did the sound of drilling produce different results to the volunteers in the study
A. It produced some worry in the volunteers in the low-fear group.
B. For the low-fear group, it activated the brain area dealing with learning, feelings and memory.
C. For the high-fear group, it caused more activities in the brain area relative to auditory processing.
D. It made people in the high-fear group remember their past uncomfortable memories.
34. What is the last paragraph mainly about
A. How the study might be useful. B. Some new ways to treat teeth.
C. The proper way to treat dental patients. D. The importance of keeping our teeth healthy.
35. What's the purpose of the passage
A. To show us different areas of fear in brains.
B. To introduce us a recent survey by a scientist.
C. To help us have less fear of a trip to the dentist.
D. To make it clear that the sound of drilling is not terrible.
四、任务型阅读（共5小题；每小题2分，满分10分）
Many years ago, I could hear nothing with one of my ears suddenly. At first, I thought it was just a small problem. But two days later, after taking the medicine that the hospital had given me, my hearing still didn't return. Soon after that, my doctor told me I had a brain tumor (瘤). So I had to spend time alone because of my illness. However, that gave me the chance to work on my favourite hobby — art.
I had spent most of my time in college studying art, wishing to find a way of mixing technology into my work. But I never thought I could do technical (技术的) work, much less be a technologist, because I hardly learned about it.!
To learn more about technology, I went through a course in hardware and software engineering (硬件和软件工程) and fell in love with computers and code so that I mixed them into my artwork.
I've learned many things during this whole process. We should try to turn something bad that happened to us into something good. We must never give up if we want to be successful. I believe in myself.

Second, if there is any problem about food safety, our school leaders will know and solve it in time. Also, the cafeteria workers are trying to provide different kinds of food for us. In Other words, our parents needn't worry about our diet anymore.
