第一篇
What We Take from And Give to the Sea
As long as we have been on earth, we have used the sea around us. We take from the ocean, and we give to it.
We take fishes from the ocean - millions of kilograms of fish, every year, to feed millions of people. (1) We take minerals from the ocean. One way to get salt is to place seawater in a shallow basin and leave it until it evaporates. (2) Much gold and silver drift dissolved in the waters of the sea, too1. But the sea does not give them up by simple evaporation. Other gifts from the sea are pearls, sponges and seaweed. Pearls become jewelry. (3) Seaweed becomes food of many kinds – even candy, and ice cream - as well as medicine. Believe it or not, fresh water is another gift from the sea. We cannot drink ocean water. (4) But ocean water becomes fresh water when the salts are removed. In the future, we will find ourselves depending more and more on fresh water from the sea.
The sea gives us food, fertilizer, minerals, water, and other gifts. What do we give the sea? Garbage. (5) Huge as it is, the ocean cannot hold all the water that we pour into it. Dumping garbage into the ocean is killing off sea life2. Yet as, the world population grows, we may need the sea and its gifts more than ever.
We are finally learning that if we destroy our seas, we might also destroy ourselves. Hopefully, it is not too late.
词汇：
Fertilizer n.化肥
evaporate v.蒸发
Sponge n.海绵
seaweed n.海草
Garbage n.垃圾
注释：
1. Much gold and silver drift dissolved in the waters of the sea, too.
还有不少金和银的漂流物溶解在海水里。
2. Dumping garbage into the ocean is killing off sea life.
把垃圾往大海里倾倒就是在把海洋生物杀绝灭尽。
练习：
A. Natural sponges become cleaning aids.
B. We pollute the ocean when we use it as a garbage dump.
C. The area of the sea is becoming smaller and smaller.
D. Along with salt, other minerals ~.re left after evaporation.
E. We even use their bones for fertilizer.
F. Some of its contents may cause illness.
答案与题解：
1. E 前面一句讲了我们从大海捕捉大量的鱼供人们食用，这句接着说讲“甚至连鱼的骨头也被用来做化肥”。Even这个词在这里清楚地表示了这两句话的关系。
2. D 这句话的前一句讲的是我们可以通过水的蒸发从海水中得到一种矿物质——盐，这句话则说除了盐之外，水蒸发以后还有别的矿物质留下来。
3. A 前面讲到了除了矿物质外，大海还给了我们珍珠、海面和海草这三样东西。接着作者分别用一句话来说明每一样东西的用途。先讲了珍珠，最后讲的是海草，多以这中间的一句应该是讲海绵的用途了。
4. F 前一句话说了我们不能喝海水，这句话解释了为什么不能喝，很自然。
5. B 前面一句话用garbage一个单词有力地回答了“我们给予大海什么”这个带有自责的问题，这句话则是对这个简单回答的具体解释。
第十一篇
Crop Circle Mysteries
They are giant geometric patterns, which appear over-night in a field of crops. Many people believe that they are made by aliens. (1) "Crop circle", as the mysterious patterns are called, became a hot phrase this month.
(2) It's believed to be the world's first three-dimensional crop circle１.The giant crop circle gives an impression of looking down on skyscrapers from above. (3) Crop circles were first widely noticed in the late 1970s as many mysterious circles began appearing-in crop fields throughout the English countryside. People were intrigued by these giant patterns. They were huge (at least tens of meters in diameters) and popped up over-night2. (4)
Various scientific and pseudo-scientific explanations were put forward to explain the phenomenon. Some hold that they were left by alien spaceships. Others say that they are simply an elaborate prank3. (5) To date, thousands of circles have been discovered all over the globe, from the former Soviet Union to Japan to Canada.
练习：
A A strange pattern 360 feet (110 meters) in diameter was discovered earlier this month in a wheat field in Oxfordshire, England.
B Others call them hoaxes.
C No one knew how or by whom they were made.
D The design's discovery immediately generated a new tide of public interest in this mysterious phenomenon.
E Farmers often make crop circles for fun.
F But rather than discovering the truth, people saw increasingly complicated circles appear worldwide.
答案与题解：
1. B 选项B是: Others call them hoaxes.其他人把他们叫做骗局。前面一句话是：Many people believe that they are made by aliens.许多人相信它们是外星人搞的。man和others有一定的关联性。因此选B。
2. A 紧随其后的句子是：It's believed to be the world's first three-dimensional crop circle. 它被认为是世界上第一个三维的作物圈。代词在这里是一个照应词，A strange pattern 360 feet (110 meters) in diameter是合适的。因此A是正确的。
3. D 上文是：The giant crop circle gives an impression of looking down on skyscrapers from above.这个巨大的作物圈给人以一种从上向下看摩天大楼的印象。这事在讲做物权的造型或设计。因此填入D是最合适的。D说的是：The design's discovery immediately generated a new tide of public interest in this mysterious phenomenon.这一设计的发现即刻生成了一个大家关注这一神秘现象的新浪潮。
4.C 上文是：They were huge (at least tens of meters in diameters) and popped up over-night.它们巨大（直径至少有几十米）并且是一夜之间突然冒出来的。这个句子实际上已经蕴含着不知道是谁弄的以及是怎么制造出来的。因此C是合适的。C是这么说的： No one knew how or by whom they were made.没有人知道它们是如何制造出来的，也不知道是谁弄的。
5. F 上文是: Various scientific and pseudo-scientific explanations were put forward to explain the phenomenon. Some hold that they were left by alien spaceships. Others say that they are simply an elaborate prank.各种各样的科学的和伪科学解释都提了出来解释这一现象。有的说是外星人的太空飞船留下的。有的说它们只是些精美的骗局。从主题的发展来说，还可以继续争论下去，当然也可以把争论搁置起来。选项F表达的是搁置争论。从主题发展来说也是连贯的。
