Artificial (人造的) light is necessary in our modern society. But the increased use of lighting, however, can cause some problems. Light in the wrong place and at the wrong time can disturb us.        

How to prevent     1     pollution? Before answering the question, please think of a few simple     2    : Is the lighting necessary? Could safety or security be achieved by other ways? Do the lights have to be on all night? Will it matter if we     3     them off?

If lighting is the best choice, then only the right number     4     lights for the task should be installed (安装). Lighting will then become a problem if lights are poorly designed or incorrectly installed.

If lighting is necessary, a number of measures can be     5     to stop causing harm: For a family,     6     150W lamp is enough. High power (300/500W) lamps can create too     7     light. As we all know too much light is sometimes dangerous. It can make our eyes lose sight for a short time. For an all-night porch (走廊), a 9W lamp is OK in most situations.

Make sure that lights are correctly adjusted (调整) so     8     they only make the required surface bright and do not throw light onto neighboring things.

Our eyes are very important to us. They are like cameras. We can     1     with our eyes. But if we don’t take care of them, they may get hurt.     2     can we protect our eyes?

On     3     days when the sun shines brightly, we’d better wear sunglasses. When we     4    , we shouldn’t stay too close to the books and the light couldn’t be too bright or too dark. We shouldn’t read in bed. It’s     5     for our eyes. We mustn’t play games too long on computers or on mobile phones.

No matter where you are, it’s important to know how to ask for help     1     (polite).

For example, if you are in a bookstore, and you want to buy some     2     (fascinate) books. At the same time, you hope these are     3     (expensive). After a while, you want to find a restroom, but you don’t know     4     there is a washroom, so you must rush to a staff person at the door to ask. In such a situation, you can ask, “ Pardon me, is there a bathroom near here?” or “    5     (can) you tell me if there is a bathroom near here?” I think you are more polite     6     you ask direct questions.

Perhaps sometimes you can’t get the answer you want, but it’s necessary and     7     (correctly) to speak politely.     8     fact, good speakers change the way they speak in different     9     (situation). Because this will help them     10     (communication) better with other people.

【推荐1】Every day, your parents seem to try to decide everything     1     you, from the clothes you wear to what time you should go to bed. You may feel upset because you can’t do as you like. You may think they won’t understand even     2     you talk to them.

Well, that’s not true. As you are     3     (grow) older, you want to make your own decisions. But your parents may not know this. They think you’re still     4     child and need their care. Talk to your parents and tell them you’ve grown     5    . Talk to them when you have problems.

Parents are great to talk to because they     6     (real) care about you. They want to make sure you’re happy. Talking with them will help you feel a little     7     (good). They are there when you are     8     (worry).

Your friends are important. But getting ideas from parents is important, too. Your young friends don’t have all the experience that your parents have. When your parents were     9     (kid), they went through     10     same kinds of things like you. They can give you help, or they can just listen.

I hope you can understand your parents well.
