Man-made Causes

Man-made causes probably do the most damage. There are many man-made causes.  21  is one of the biggest man-made problems. Pollution  22  in many shapes and sizes. Burning fossil fuels is one thing that causes pollution. Fossil(化石) fuels(燃料)are fuels made of organic matter such as coal, or oil. when fossil fuels are burned they  23  a green house gas called CO2. Also mining coal and oil allows methane to escape. How does it escape? Methane(甲烷)is  24  in the ground.  25  coal or oil is mined you have to dig up the earth a little. When you dig up the fossil fuels you dig up the methane as well.

Another major man-made  26  of Global Warming is population. More people  27  more food, and more methods of transportation, right? That means more methane because  28  will be more burning of fossil fuels, ­ 29  more agriculture. Now you’re probably thinking, “Wait a minute, you said agriculture is going to be damaged by Global Warming, but  30  you’re saying agriculture is going to help cause Global Warming?” Well, have you  31 been in a barn filled with animals and you smell something  32 ? You re  33  methane. Another source of methane is manure. Because more food is needed we have to raise food. Animals like cows are a source of food which means more manure and methane. Another problem  34  the increasing population is  35 . More people means more cars, and more cares means more pollution. Also, many people have more than one car.

Since CO2 contributes to global warming, the increase in population makes the problem worse because we breathe out CO2.  36 , the trees that change our CO2 to oxygen are being demolished because we’re using the land that we cut the trees down from as property  37 our homes and buildings. We are not replacing the trees(an important part of our ecosystem), so we are  38  taking  39  of our natural resources and giving nothing back in  40 .

How hard we have all prayed(祈祷) to grow up quickly, and looked forward to the happy days of being a grown-up and enjoying the many interests that a youth should have.

At last, you have grown up. At least you are no longer a child. They call you “young lady”. You then enjoy the pleasure of being a young lady. You are proud of being a grown-up teenager. People welcome you-this young lady-heartily. You are glad that your prayer has been answered.

But there is always something that troubles you a lot. You say; “Papa and Mama, give me some money please. My pocket money is all gone already.”

“No”, they say, “your age is a dangerous age. If you have too much money to spend, it won’t do you any good.” Then you have to stay at home because you dare not go out with an empty pocket.

Another time you tell your grandma, “Grandma, see, I am a grown-up now.

“Good, now, you can sit here and knit (编织) this for me while I go and have a rest.” To show that you are no more a child, you have to sit there the whole afternoon doing the work, which only a grown-up can do. After an hour, you find it hard to do, and give the knitting basket back to your grandma. Your grandma criticizes your work. You hear what she says, “Such a big girl can’t do such easy work.” You wish then you were a child again.

But the fact is, you are growing up, and you can’t help it. That’s the way it goes!

Alone in the wilderness. Nothing but jungle. A world of shadow with the rays of light falling like blonde hair from the crowns of the giant trees. Jungle in the midday sun. Everything motionless. Not a sound from sky or earth. Complete silence. Only some coconuts falling, at long intervals, very far away. The world reduced to the soft touch of cool grass along my naked back, and a sweet smell of rich soil and vegetation. Stretched out with closed eyes beside my heavy burden of fruit and firewood, I enjoyed the feeling of fresh blood streaming through every part of my body and fresh jungle air filling every corner of my lungs.

     Resting motionless, I could see the sun through my closed eyelids, alone in the sky, as lonely as I, and as motionless and silent as everything else. The earth had surely stopped turning and somewhere on this planet there was supposed to be roaring traffic in busy streets. What a crazy, unbelievable thought!

         Another coconut fell, to make the world come to a complete standstill. I had to roll over onto my stomach to feel that at least I could move and make noises. Then I found company. A little brown ant was struggling to find its way with a bit of dry straw through the jungle of leaves and grass below my nose. I wondered if I could give the little fellow a lift with its burden, but it showed not the slightest sign of tiredness and struggled on with all six legs, head first or head last, waving its feelers energetically as if the trip had just started. Who ever saw a tired ant? Tiredness, disagreeable tiredness, is restricted to hunted animals, slaves and modern man. It is as great an effort for an office clerk to walk five blocks with a loaded brief-case as it is for a jungle-dweller to cross a valley with a goat on his back. It is as hard to get up and climb or run when you have been seated for years as it is to get up and walk when you have been in bed for months. The body is strange. Spare it, and you get really tired for almost nothing; use it, and almost nothing makes you really tired.

         I rose to my feet. I had heard a horse neighing down in the valley. Above me, on the open highland plains, there were wild horses. But down in the valley there was never a horse unless there was a man on it. Somebody was making his way up the valley and my wife was alone.

         A．show his loneliness                                                           B．add beauty to the jungle

         ② I went to the jungle.

         ③ I found an ant carrying a bit of dry straw.

         ④ I lay on the ground to have a break.

         ⑤ I picked fruits and chopped firewood.

A. ②③⑤①④                 B. ⑤③②④①                          C. ②⑤④③①                 D. ⑤④③②①

73．How does the author feel about the ant?

         A．He admired its attitude toward work.

         B．He was amazed at its tireless efforts.

         C．He showed sympathy for the little ant.

         D．He was content to have it as a companion.

         A．work harder than before                                                 B．talk to the man on the horse

         C．make his way home                                                          D．stay in the valley

I’m sure many of you have seen Star Wars, Jurassic Park, Multiplicity, or many of the other movies that describe cloning. Most of what you see in these movies is false. What you don’t know is that cloning could be dangerous, to the clone and to our society as a whole. I think human cloning is wrong mainly for four reasons.

What about identity? Humans are promised the right to their own personalities. What would happen if we ignore those rights by giving them someone else’s genetic identity? True, Cloning may prevent people from possessing their identities.

Also, these is a large power struggle here. Cloning means a degree of power and controls over another person’s physical identity and that ignores their rights and their only personalities. The person doing the cloning would have more power than any parent would have.

Cloning would also deal with killing embryos (胚胎). You might not have known, but Dolly, the sheep that was cloned in 1996, was one of over 200 sheep embryos and hers was the only embryo that survived. The rest died or were thrown away. Imagine if the failure rate was that high when we started to clone humans. cloning means running the risk of wasting too much effort

Cloning someone, at this present time, would be extremely dangerous to the birth mother and the clone. In studies done on cows, 4 out of 12 birth mothers died. There is a very high failure rate, which is shown in the cloning of Dolly. Even if you had a few good embryos, failures have been noticeable in animal tests.

So, should we work ahead in the world of cloning? I say no. the risks are greater than the benefits. It’s dangerous to the clone and to the birth mother. We would be killing human lives in the process. It would also be a violation(侵害) of the clone’s right to its own genetic identity and personality.

1.The author thinks human cloning is wrong mainly for ______ reasons.

A．human cloning is much more difficult than animal cloning

B．there are 200 sheep successfully cloned.

C．cloning means running the risk of wasting too much effort

D．numbers of baby animals are likely to be created by cloning
