Computers can injure you. Most other injuries happen suddenly. For example, if you fall off a bike and break your arms, it happens very quickly. But computer injuries slowly.
You probably know how to ride a bike safely. Now learn to use a computer safely.
Your eyes
Too much light can injure your eyes, so never sit too close to a computer screen. Your eyes should be at least 50 centimeters from the screen. Remember to look away from it sometimes. This gives your eyes a rest.
When you use a computer, the window should be on your left or your right. If it is behind you, the light will reflect on (反射) the screen. If the window is in front of you, the sun and the screen will both shine into your eyes.
Your hands and wrists (手腕)
Hand and wrist injuries can happen because the hands and wrists are moved in the same way hundreds of times. If you use a keyboard for a long time, follow these three rules: 1) Rest your wrists on something. 2) Keep your elbows (肘部） at the same height as the keyboard. 3) Stop something and exercise your hands, wrists and fingers in a different way.
Your back
Some people sit for many hours in front of a computer. If you sit in the wrong way, you can injure your back or your neck. So you should sit with your back straight. The top part of the screen should all be in front of your eyes. Your forearms（前臂）, wrists, hands and the upper（上部） part of your legs should all be parallel (平行) to the floor. If you are sitting for a long time, get up every 30 minutes and exercise your arms, legs and necks.

Many of us feel uneasy when someone stands too close to us, talks to us too loudly or makes eye contact(接触) with us for too long. But have you ever wondered why those things make you uncomfortable?
It’s all about personal peace, which means not only an imaginary space around the body, but also the space around all the senses. People feel that their space is being violated(侵犯) when they meet with an unwelcome sound, smell or look. This is probably why a man on a crowded bus shouting into his mobile phone or a woman next to you putting on strong perfume(香水) makes you feel angry.
Whether people have had a stronger wish to protect their personal space in recent times is hard to say. Yet studies of airlines show that people have a strong desire(渴望) to have space to themselves. In a survey by TripAdvisor, a travel website, people said that if they had to pay more for some extra service, they would rather have larger seats than extra food.
Although people may need their personal space, some hardly realize it. For example, people on a bus who hold newspapers in front of their faces to read in fact keep a distance from strangers.
Go and watch a library table. You will notice that one of the corner seats will usually be taken first, because they are the farthest way. What if someone sits opposite to you? Maybe you will pile up books as if to make a wall.
Preference(偏好) for personal space are different from culture to culture. Scientists have found that Americans generally prefer more personal space than people from other cultures. In Latin(拉丁人的) cultures, however, people are more comfortable standing close to each other.The writer mainly _________ in this article.

| B．A person who has been watched by a stranger for a long time. |
| C．A person who hears strange noises when reading at home. |
| D．A Latin boy who is chatting with a friend sitting close to him. |
What can we know from the survey by TripAdvisor?
| A．People need a smaller personal space in recent times than before. |
| B．People have a strong desire for personal space in recent times. |
| C．There are not enough seats on the plane to meet people’s needs. |
| D．Food service is better provided than seats on the plane. |
Which of the following is TRUE according to the passage?

| D．Different cultures share the same preferences for personal space. |
One of sweetest memories as a child is of going down to the river and sitting comfortably on the bank. There I would enjoy the peace and quiet, watch the water rush downstream and listen to songs of birds. I would also watch the bamboo trees bend under the pressure from the wind and watch them return gracefully to their original state after the wind had died down.
When I think about the bamboo tree’s ability to bend and move back, the word “resilience” comes to my mind. When it is used for a person, this word means the ability to readily recover(恢复) from shock, sadness or any other suffering. Have you ever felt like you were going to snap? Have you ever felt like you were at your breaking point? Thankfully, you have survived to talk about it.
Life is a mixture(混合) of good times and bad times, happy moments and unhappy moments. The next time you are experiencing one of those bad times or unhappy moments that take you close to your breaking point, bend, but don’t break. Try your best not to let the situation get the best of you.
An amount of hope will take you through the unpleasant suffering. With hope for a better tomorrow or a better situation, things may not be as bad as they seem. The unpleasant suffering may be easier to deal with if the end result is worth having.
If things get tough and you are at your breaking point, show resilience. Like the bamboo trees, bend, but don’t break!What does the word “snap” in the second paragraph most probably mean?
| A．break | B．change |
| C．win | D．Complain |
What can help people get through sufferings according to the writer?
| A．Holding peace and quiet in mind. | B．Waiting until sufferings disappear. |
| C．Experiencing more bad times. | D．Hoping for a better tomorrow. |
What would be the best title of this passage?
| A．Memories of Bamboo | B．Be Like Bamboo |
| C．Enjoying Bamboo | D．Characteristics of Bamboo |
Have you ever noticed that your fingertips are winked when you’ve just finished swimming or washing dishes? It seems as if your hands have aged 30 years in a second. But is this an accident? Or is it something that nature has built into our bodies?
If your finger’s wrinkling up had no use at all, “ it wouldn’t need to.” Professor Tom Smulders from Newcastle University, UK, told BBC News. By studying wet fingers closely, Smulders and his partners found that the wrinkles looked a bit like the patterns on the car tire or on the bottom of the running shoes. So they made a guess that wrinkles on fingers might be able to help the hand hold things more tightly.
To test this, researchers asked 20 people to pick up marbles from water with their hands. But before they started, some of the people had to keep their hands in water for half an hour.
The researchers found that the people with wrinkled fingers completed the task the task faster than those with dry hands. But when they were asked to move dry marbles, all the people performed equally well, no matter they had the wrinkled fingers or not.
Our ancestors might not have played with marbles, but wrinkled fingers could have made it easier for them to climb around in the wet forests and catch fish from rivers, researchers say.
Similarly, our toes also get wrinkled in water. This may have developed from our ancestor’s need to run on wet ground.
But the question is, if wrinkled fingers are so helpful, why don’t our hands just stay that way all the time? Researchers explained that wrinkling has its disadvantage: wet fingertips are far less sensitive than smooth ones, reducing our sense of touch.What does the underlined world “this ” in the third paragraph refer to?
| A．Whether fingers have wrinkles after they are put in water. |
| B．Whether wrinkled fingers can hold things more tightly. |
| C．Why keeping things in water makes them wrinkled. |
| D．Why wrinkles help hands hold things more tightly. |
The test shows that ________.
| A．winkled hands hold dry things more tightly than dry hands do. |
| B．dry hands hold dry things more tightly than wrinkled hands do. |
| C．winkled hands hold wet things more tightly than dry hands do. |
| D．dry hands hold wet things more tightly than wrinkled hands do. |
What might be the disadvantage of wrinkled fingers?
| A．They are too sensitive to be touched. |
| B．They might be more likely to get hurt. |
| C．They cannot hold things tightly enough. |
| D．They are not so sensitive as dry fingers. |
We were doing the best to control the fire of the burning garage. Outside, I heard the sounds of cats crying. I couldn’t stop- I would have to look for the cats after the fire was put out.
It took a long time to finally bring the big fire under control. No one inside was hurt. At that point I was free to find out where the cat noises were from. There was still a lot of smoke and heat coming from the building. I followed the meowing to the sidewalk in front of the garage. There, crying and huddled together, were five frightened kittens . They must have been inside the building, as their fur was badly hurt.
I wanted to find the mother cat. It was obviously that she had gone into the burning garage and carried out all her babies, one by one----unbelievable.
We finally found her. Her paws and face were blackened, and her fur was burned all over. You could even see her reddened skin under the burned fur. She could hardly move. I picked her up, and she relaxed in my arms as much as her pain would allow. I was determined to save this brave little cat and her family.
The veterinarian told me they would watch the kittens and their mother for the night, but they weren’t confident about the about the mother’s chances.
About a week later, I found out she was going to live. We named her Scarlet because of her reddened skin.
I was happy to see Scarlet get together with the kittens again. She touched each of them, nose to nose. She had risked her life five times-and it had paid off. All of her babies had survived.
As a firefighter, I see heroic acts every day. But what Scarlet showed me that day was the kind of bravery that can only come from a mother’s love.Which f the following is TRUE according to the story?
