Why is a full moon, yellower and bigger when it is coming up than when it is higher in the sky?

That's a good question about something that we all can see. Let's talk about the moon's color first.
We see the moon only because of the sunlight that falls on it and is reflected. Actually, the moon is not a very good reflector, because its surface is all rocks and dirt. We see it in almost its true color when it is high in the sky.
When the moon first comes up, its light reaches our eyes after an extra-long path through the atmosphere (大气). There are lots of particles (微粒) scattering (分散) light in that long path. Blue light is scattered more than other colors, which means that it doesn't reach your eyes. The light that is left over looks yellow to your eye.
Now about the other question—why the moon seems to change in size. That's more complicated. It's not an effect of the atmosphere, the way color is; it's not caused by something fooling your eyes. It seems, instead, to be caused by something that fools your brain—an illusion(错觉).
Here's a drawing that creates an illusion. The two cones(圆锥体) are really the same size. But the rest of the drawing makes the right-hand cone seem farther away. Your brain knows that faraway objects are really larger than they look. It decides that the right-hand cone must be larger because it seems to be farther away.
Similarly, when you see the moon just come up over a line of trees or houses—or whatever makes the horizon(地平线)—it may be that your brain decides that the moon must be larger because it seems to be farther away.

Tight-lipped elders used to say, "It's not what you want in this world, but what you get．"
Psychology teaches that you do get what you want if you know what you want and want the right things．
You can make a mental blueprint of a desire as you would make a blueprint of a house, and each of us is continually making these blueprints in the general routine of everyday living．If we intend to have friends to dinner, we plan the menu, make a shopping list, decide which food to cook first, and such planning is an essential for any type of meal to be served．
Similarly, If you want to find a job, take a sheet of paper, and write a brief account of yourself．In making a blueprint for a job, begin with yourself, for when you know exactly what you have to offer, you can intelligently plan where to sell your services．
This account of yourself is actually a general description of your working life and should include education, experience and references．Such an account is valuable．It can be referred to in filling out standard application blanks and is extremely helpful in personal interviews．While talking to you, your could-be employer is deciding whether your education, your experience, and other qualifications will pay him to employ you and your abilities must be displayed in an orderly and reasonably connected manner．
When you have carefully prepared a blueprint of your abilities and desires, you have something tangible to sell．Then you are ready to look for a job．Get all the possible information about your could-be job．Make inquiries about the details concerning the job and the firm．Keep your eyes and ears open, and use your own judgment．Spend a certain amount of time each day seeking the position you wish for, and keep in mind: Obtaining a job is your job now．
【小题1】What do the elders mean when they say, “It’s not what you want in this world, but what you get．”?

 A new study warns that about thirty percent of the world’s people may not have enough water by the year 2025.

An American organization called Population Action International did the new study. It was more than three hundred and thirty-five million people lack enough water now. The people live in twenty-eight countries. Most of the countries are in Africa or in the Middle East.

Population Action International researcher Robert Engelman says by the year 2025, about three thousand million people lack water. At least 18 more countries are expected to have serious water problems. The demand for water keeps increasing. Yet the amount of water on the earth the same. Mr Engelman says the population in countries that lack water is growing in these countries will continue to increase.

The report says lack of water in the future may result several problems. It may increase health problems. Lack of water often means drinking water is not safe. Mr Engelman says there are problems all over the world because of diseases such as cholera that are carried in water.

Lack of water also may result in more international conflict. Countries may have to fight for water in the future. Some countries, such as Syria, Sudan, Cambodia, and so on, now get sixty percent of their fresh water from other countries. And the report says lack of water would affect the ability to improve their economies. This is because industries often need a large amount of water.

The Population Action International study gives several ways to solve the water problem. One way is to find ways to use water for more than one purpose. Another way is to teach people to be careful not to waste water. A third is to use less water for agriculture. The report also says long-term solutions to the water problem must include controls on population growth.
