Trees are useful to man in three very important ways: they provide him wood and other products; they give him shade; and they help to prevent drought (干旱) and floods.    Unfortunately, in many parts of the world, man has not realized that the third of these services is the most important. In his eagerness to draw quick profit from the trees, he has cut them down in large numbers.   Two thousand years ago, a rich and powerful country cut down its trees to build warships, with which to gain itself an empire. It gained the empire but, without its trees, its soil became bare and poor. When the empire fell to pieces, the country found itself faced by floods and starvation.   Even where a government realizes the importance of a plentiful supply of trees, it is difficult sometimes to make the people realize this. They cut down the trees but are too careless to plant and look after new trees. So, unless the government has a good system of control, or can educate the people, the forests slowly disappear.   This does not only mean that there will be fewer trees. The results are even more serious: for where there are trees, their roots break the soil up, allowing the rain to sink in, and also bind the soil. This prevents the soil from being washed away. But where there are no trees, the rain falls on hard ground and flows away on the surface, and this causes floods and the rain carries away the rich topsoil in which crops grow. When all the topsoil is gone, nothing remains but worthless desert. (4.0 分)1.

Like most people, I was brought up to look upon life as a process of getting. It was not until in my late thirties that I made this important discovery: giving-away makes life so much more exciting. You need not worry if you lack money. This is how I experimented with giving-away. If an idea for improving the window display of a neighborhood store flashes to me, I step in and make the suggestion to the storekeeper. One discovery I made about giving-away is that it is almost impossible to give away anything in this world without getting something back, though the return often comes in an unexpected form. One Sunday morning the local post office delivered an important special delivery letter to my home, though it was addressed to me at my office. I wrote the postmaster a note of appreciation. More than a year later I needed a post-office box for a new business I was starting. I was told at the window that there were no boxes left, and that my name would have to go on a long waiting list. As I was about to leave, the postmaster appeared in the doorway. He had overheard (无意中听到) our conversation. “Wasn’t it you that wrote us that letter a year ago about delivering a special delivery to your home?” I said yes. “Well, you certainly are going to have a box in this post office if we have to make one for you. You don’t know what a letter like that means to us. We usually get nothing but complaints.”(4.0 分)6. From the passage, we understand that _________ .A.the author did not understand the importance of giving until he was in late thirtiesB.the author was like most people who were mostly receivers rather than giversC.the author received the same education as most people during his childhoodD.the author liked most people as they looked upon life as a process of getting(4.0 分)7. According to the author ___________ .A.giving means you will lack moneyB.the excitement of giving can bring you moneyC.you don't have to be rich in order to giveD.when you give away money, you will be rich(4.0 分)8. The author would make the suggestion to the storekeeper___________ .A. in writingB.in personC.in the window displayD.about the neighborhood(4.0 分)9. When the author needed a post-office box, _________ .A.he had to put his name on a waiting listB.he wrote the postmaster a note of appreciationC.many people had applied for post-office boxes before himD.he asked the postmaster to make one for him(4.0 分)10.In reply to the postmaster's question, the author said _________ .A.it was the special deliveryB.it was the post-office boxC.it was the note of appreciation he wroteD.it was he who wrote him a letter a year ago
