At the various times when I have helped you a little, you have said to me, "We can get along very well again," but in a very short time I find you in the same difficulty again. Now this can only happen by some fault in your behavior. What that fault is, I think I know. You are not lazy, and still you are an idler . I doubt whether since I saw you, you have done a good whole day's work, in any other day. You do not very much dislike to work, and still you do not work much, merely because it does not seem to you that you could get much for it. This habit of uselessly wasting time is the whole difficulty; it is vastly important to you, and still more so to your children, that you should break this habit. It is more important to them, because they have longer to live, and can keep out of an idle habit before they are in it, easier than they can get out after they are in. You are now in need of some ready money; and what I suggest is, that you shall go to work hard, for somebody who will give you money for it. Let father and your boys take charge of your things at home-prepare for a crop, and make the crop, and you go to work for the best money wages, or to pay back any debt you owe. And to secure you a fair reward for your labor, I now promise you that for every dollar you will, between this and the first of May, get for your own labor, I will then give you one other dollar. By this, if you hire yourself at ten dollars a month, from me you will get ten more, making twenty dollars a month for your work. Now if you will do this, you will soon be out of debt, and what is better, you will have a habit that will keep you from getting in debt again. But if I should now clear you out, next year you will be just as deep in as ever. You say you would almost give your place in Heaven for $ 70 or $80. Then you value your place in Heaven cheaply, for I am sure you can with the offer I make you get the seventy or eighty... Question: Abraham Lincoln wrote the letter to Johnston mainly to _ .

Read the article and select the best answer. Article: Special trees that grow faster, fight pollution, produce better wood, and even sense chemical attacks are being planted by scientists in the US. When 40 per cent of Hawaii's US$14 million-a-year papaya industry was destroyed by a virus five years ago, work began on creating genetically engineered trees. Researchers successfully introduced seeds that were designed to resist the virus.Since then, more and more people have been testing genetically engineered trees.Some researchers put special bacteria into trees to help them grow faster and produce better wood.Others are trying to create trees that can clean polluted soil.Meanwhile fruit farmers are looking for trees that are strong enough to resist worms, and paper companies want trees that produce more wood and therefore more paper. The Pentagon even gave the researchers US$500,000 this year after they developed a pine tree that changes its colours if it senses a chemical attack.So far, the poplar, eucalyptus , apple and coffee trees are among those being engineered.All this can be done today because we have a better understanding of tree genomes . However, some people fear that the genetically engineered trees will cause dangerous results.They are worried that the new trees will breed with natural species and change the balance of the forest environment. "It could be destructive," said Jim Diamond, an environmentalist. "Trees are what is left of our natural environment and home to many endangered species." But researchers insist that science could give nature a fighting chance against both natural and man-made dangers.They hope to answer the critics by stopping the new trees from breeding, so their effect on the environment can be controlled. Question: What caused the American scientists to work on special trees? Options: A: Tree genomes are mapped out so scientists know how to improve trees. B: Great numbers of trees have been lost due to attacks by viruses. C: Researchers successfully introduced seeds designed to resist the virus. D: They think science could give nature a fighting chance against both natural and man-made dangers.

Read the article and select the best answer. Article: Habits, whether good or bad, are gradually formed. When a person does a certain thing again, he is impelled(,) by some unseen force to do the same thing repeatedly; thus a habit is formed. Once a habit is formed, it is difficult, and sometimes impossible, to get rid of. It is therefore very important that we should pay great attention to the formation of habits. Children often form bad habits, some of which remain with them as long as they live. Older persons also form bad habits as long as they live, and sometimes become ruined by them.. There are other habits which, when formed in early life, are of great help. Many successful men say that much of their success has something to do with certain habits in early life, such as early rising, honesty and thoroughness . Among the habits which children should not form are laziness, lying, stealing and so on. These are all easily formed habits. Unfortunately older persons form habits which ought to have been avoided. We ought to keep from all these old habits, and try to form such habits as will prove good for ourselves and others. Question: The bad habits formed by _ Options: A: children sometimes stay in all their lives B: older people sometimes can kill them C: persons sometimes can remain with them D: younger people sometimes can break them
(Answer)
A
