Many textbooks are not written in the kind of English that we speak，every day．In fact，sometimes the reading is so difficult that it almost seems like a foreign language．In a way，it is the language of science．You should not expect to be able to read a difficult science passage the same way you read an interesting story，you should not expect to read it easily and all at once．Instead，you may have to read it several times through，catching on the meaning of difficult words，going back over difficult sentences，and finally putting the whole thing together．Do not be discouraged if the whole passage doesn't make sense to you at first．You  need to pick it apart patiently until you can understand it．

These are the steps to follow when you' are reading something difficult:

1．Start to read normally until you run into a sentence that doesn't make sense to you．

2．When a sentence doesn't make sense，go back and read it again more slowly．

3．Look for any words you don't know in the sentence．Try to understand their meanings using word parts and context clues（上下文线索）．If necessary，look them up in the dictionary．

4．Look at the next few sentences to see if they explain more about the sentence you are working on．Do not read very much farther ahead until you understand what is being said．

5．Finally，read the sentence again．Try to put it into simpler words．

6．Read through the passage once．Try to understand all the hard parts well．Then read the whole passage once more at a usual speed．This helps you to put all ideas together．

The steps sound a lot harder than they are．It is really just the normal way good readers understand anything that is difficult to read．After you have done the best you can this way，you should always feel free to ask for help from your teacher，if you have one．

“Cool” is a word with many meanings. It means a little cold at first. As time changes, the word gets many different meanings. We can use “cool” when we talk about something wonderful or somebody looking smart. For example. When you see a beautiful and expensive car in the street, you can say, “It is cool.” You may think the famous film star Keanu Reeves is cool. You can also use the word to mean something new and surprising. Here is an example. One day a teacher took the students to a farm and then asked them to write something about the visit. One of her students just wrote, “The farm is so cool.” Because he thought “ cool” was the best word to show what he saw and felt. It also shows some people don’t have enough words.

Children can spend hours a day looking at computer screens and other digital devices. Some eye doctors say this leads to an increase in “computer vision syndrome(电脑视力综合症).”
Nathan Bonilla-Warford is an optometrist（验光师）in Tampa, Florida. He has seen an increase in problems in children. “A lot more children come into the office either because their parents have noticed that they have headaches or red or watery eyes or discomfort, or because their nearsightedness appears to be increasing and they’re worried,” he says.
Dr. Bonilla-Warford says part of the problem is that children may be more likely to pay no attention to early warning signs than adults. “Even if their eyes start to feel uncomfortable or they start to get a headache, they’re less likely to tell their parents, because they don’t want to have the game or the computer or whatever taken away,” he explains.
He says another part of the problem is that people blink（眨眼）less often when they use digital devices. He says, “A person who uses an electronic device blinks about one third as much as we normally do in everyday life. And so that can result in the front part of the eye drying and not staying protected like normal.”[来源:Z.xx.k.Com]
Eye doctors offer suggestions like following which is known as the 20/20/20 rule. That means every twenty minutes look away twenty feet or more for at least twenty seconds from whatever device you’re using.
Other suggestions include putting more distance between you and the device and using good lighting. Of course, another way is to spend less time looking at screens. Many experts say children should spend no more than two hours a day using digital devices—with no screen time for children under two.
But not all eye doctors have noticed an increase in problems in children. Dr. David Hunter, from Children’s Hospital Boston, has not seen an increase in his practice. “While it is possible to develop fatigue looking at screens for a long period of time, there’s certainly no proof that it actually causes any damage（伤害）to the eyes.” he says.
