Every 38 gets its light either from daylight 39 the window or from the lamps, 40 no matter what kind of light it is, the way it shines is very important to the eyes.
Take a book and sit with your 41 towards the window, and try to read. Your shadow(影子) falls all over the page and makes it 42 for your eyes as if you were in a 43 room. Now turn around and face the window. The page is in shadow again, 44 the bright light is in your eyes.Try sitting with your 45 side towards the window. This is very good for reading, but if you were writing, the shadow 46 fall across the page and trouble you 47 .There is another way – sit 48 your left side to the window. Now everything is perfect for 49 as well.
Whatever kind of light is in the room, the rule about the right way to sit is 50 the same. So you see different ways to sit make much difference in writing or studying.

核心考点
试题【If you are writing or studying, it makes much difference where the light comes f】；主要考察你对科普环保类等知识点的理解。[详细]
举一反三
In some places the sun is not hot enough. Or it does not shine every day.
In such places other ways of heating sea water can be used. These ways cost more money, but they work faster than the sun. By boiling sea water with high heat a lot of fresh water can be made quickly.
But heating is not the only way to get fresh water from salt water. Other ways are tried.
One way is freezing. The fresh part of salt water freezes first. To get fresh water, the bits of ice are taken out.
Which way is the best? The one that gives the most water for the least money. It may be a different way for each place.
Symi’s way seems very good for small, hot places. It does not make much water at a time. But the factory is easy to build and costs little.
That is why people in many dry places talk about Symi.
小题1:From the passage we know that fresh water _____________.
| A．is needed in many countries | B．is needed in every country |
| C．can be used in many ways | D．is very important for factories |
| A．turns salt water into fresh | B．can be built everywhere |
| C．can make much fresh water at a time | D．doesn’t need sunshine every day |
| A．Boiling the sea water. | B．Heating the sea water. |
| C．The Symi’s way. | D．Freezing the sea water. |
| A．New ways of getting fresh water. |
| B．A lot of fresh water can be made quickly by heating. |
| C．The best way is to get the freshest water with the least money. |
| D．The Symi’s way doesn’t work in dry places. |
| A．small | B．hot | C．cool | D．dry |
Also, you should remember that it is your duty to do your homework. Next time, when you want to depend on(依靠) Mom and Dad for help, please try to find the answer yourself, because you will learn much, much more that way.
When you have a question, especially something about a science or math, don’t always turn to your teacher! It is a good idea to try to find the answer yourself. If this doesn’t work, you can also look at the materials in the back of the book. They may guide you to the pages you should look at to help you understand the problem.
Finally, while doing homework, don’t think about or do other things. Keep working. Setting a time limit(限制) often helps with this. Different ages decide different amounts of time. 10-15 minutes is good for a child that’s aged 6-8. A time of 20-30 minutes is about right for a child aged 9-12. Kids can keep studying for 30-45 minutes from the ages of 13 to 15. This, of course, depends on your abilities to pay attention and stay on tasks.
小题1:In the first paragraph, the writer mainly tells us that ______.
| A．doing homework is the first thing you should do at home |
| B．after-school activities can’t affect doing homework |
| C．parents can help kids with their homework at night |
| D．kids need a good rest after school |
| A．students should ask the teacher more questions |
| B．thinking over the questions before asking others is important |
| C．problems can’t be solved without a teacher’s help |
| D．students shouldn’t always look at the materials in the back of the book |
| A．not to look away while doing homework |
| B．to do homework by themselves |
| C．not to turn to teachers when doing homework |
| D．to do their homework quickly and in the right way’ |
33 your time carefully. You should make a 34 of things that you have to do. First write down the time for eating, sleeping, dressing, etc. Then decide on a good time for studying. Of course, studying shouldn’t take all of your time. Don’t 35 to leave yourself enough time for hobbies.
Find a good place to study. Look around the house 36 a good study place. Keep this space. It may be a desk or just a corner of your room. N0 37 , radio, or television! When you sit down to work, think only about the 38 !
Make good use of your time 39 . Listen carefully to what the teacher says. Careful listening means 40 work after class. You also need to take notes, because it can make it easier for you to learn well.
These are only some of the ways to help you with your studying. I believe you’ll find more other ways besides these.
