题目内容

【题目】Box jellyfish （箱型水母）are the most poisonous marine animals known to man. They measure 3 meters long and weigh up to 2 kilograms. They are pale blue and transparent in color, and get their name from the cube--like shape of their body, Box jellyfish have 6 eyes on all 4 sides of their body, although it is uncertain how they process what they see as they do not have a central nervous system. They also have up to 15 tentacles （触须）growing from each corner of their body that have about 5,000 stinging（带刺的）cells each.

Box jellyfish can be found primarily in the coastal waters off Northern Australia as well as throughout the Indo--Pacific. They prefer to live at river mouths. They do not have any organs to breathe, and will sleep on the ocean floor from 3 pm to dawn. Unlike other jellyfish that merely move along with the current, box jellyfish have developed a way to travel wherever they want to go. They will shoot themselves in a jet-like fashion, reaching speeds of up to 7.4 kilometers per hour.

The diet of box jellyfish consists of thing like fish, small animals, and even other jellyfish. They use their venom, a chemical which causes heart, skin, and breath failure, to kill their prey（猎物）. Since box jellyfish have eyes, some scientists believe that they actively hunt their prey while others insist that they are just passive opportunists that will wait and catch anything that wanders into their tentacles.

Box jellyfish are responsible for more human deaths in Australia than snakes, sharks, and salt-water crocodiles combined. It is best to avoid them as most stings(刺) will result in death. Hopefully, humans and box jellyfish can find a way to live with one another while keeping conflicts to a bare minimum. After all, such a unique species of jellyfish deserves to live and grow just as humans do.

【1】What do we NOT know about box jellyfish from the first paragraph?

A. Its size. B. Its hardness.

C. Its color. D. Its poisonousness

【2】What can be learned about box jellyfish from Paragraph 2?

A. They live in the deep sea in groups

B. They can breathe on the ocean floor.

C. They usually move along with the current.

D. They can decide the direction in which they move.

【3】 The underlined word “they” in Paragraph3 refers to ________.

C. box jellyfish’s prey

D. box jellyfish’s tentacles

试题分析: 箱式水母的毒性对人类来说是最毒的。箱型水母主要在澳大利亚北部以及整个印度洋 —太平洋沿海水域。箱形水母的食物包括鱼、小动物和甚至其他水母一样的东西。它的刺能致人死亡。

【1】B 细节理解题。第一段的第一句话说箱式水母的毒性对人类来说是最毒的；第二句话说它的大小；第三句话说颜色是浅蓝色的；接下来介绍名字的由来，还有身体特征。所以没有说它的硬度，故选B。

【2】D 推理判断题。第二段的大意是：箱型水母主要在澳大利亚北部以及整个印度洋 —太平洋沿海水域。他们更愿意住在河流的入海口。他们没有呼吸器官，会从下午3点到黎明睡在海底。不同于其他只是随着水流移动的水母，箱形水母可以去他们想要去的地方。所以选择D。

【3】A 词义推测题。根据该词所在的第二段的内容可知，they前面一直在介绍箱式水母的生活习性，本句是说它们在水中移动的方式和速度。故选A。

【4】A 主旨大意题。本文主要是介绍了箱式水母这种海洋生物的体型特征、生活习性和它对人类的毒性。故选A。

【题目】Once when I was facing a decision that involved high risk, I went to a friend. He looked at me for a moment, and then wrote a sentence containing the best advice I have ever had: Be bold and brave — and mighty (强大的) forces will come to your aid.

Those words made me see clearly that when I had fallen short in the past, it was seldom because I had tried and failed. It was usually because I had let fear of failure stop me from trying at all. On the other hand, whenever I had plunged into deep water, forced by courage or circumstance, I had always been able to swim until I got my feet on the ground again.

Boldness means a decision to bite off more than you can eat. And there is nothing mysterious about the mighty forces. They are potential powers we possess: energy, skill, sound judgment, creative ideas — even physical strength greater than most of us realize.

Admittedly, those mighty forces are spiritual ones. But they are more important than physical ones. A college classmate of mine, Tim, was an excellent football player, even though he weighed much less than the average player. “In one game I suddenly found myself confronting a huge player, who had nothing but me between him and our goal line,” said Tim. “I was so frightened that I closed my eyes and desperately

threw myself at that guy like a bullet（子弹） — and stopped him cold.”

Boldness — a willingness to extend yourself to the extreme—is not one that can be acquired overnight. But it can be taught to children and developed in adults. Confidence builds up. Surely, there will be setbacks (挫折) and disappointments in life; boldness in itself is no guarantee of success. But the person who tries to do something and fails is a lot better off than the person who tries to do nothing and succeeds.

So, always try to live a little bit beyond your abilities and you’ll find your abilities are greater than you ever dreamed.

【1】What is the implied meaning of the underlined part?

A. Swallow more than you can digest.

B. Act slightly above your abilities.

C. Develop more mysterious powers.

D. Learn to make creative decisions.

【2】What was especially important for Tim‘s successful defense in the football game?

A. His physical strength. B. His basic skill.

C. His real fear. D. His spiritual force.

【3】What can be learned from Paragraph 5?

A. Confidence grows more rapidly in adults.

B. Trying without success is meaningless.

C. Repeated failure creates a better life.

D. Boldness can be gained little by little.

【4】What is the author’s purpose in writing this passage?

A. To encourage people to be courageous.

B. To advise people to build up physical power.

C. To tell people the ways to guarantee success.

D. To recommend people to develop more abilities.

【题目】We can’t deny that trees are useful to man in three very important ways: they provide him with wood and other products, they give him shade, and they help to prevent drought 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, only to find that without them he has lost the best friends he had.

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 hard and poor. When the empire fell to pieces, the country found itself faced by floods and starvation.

Even though a government realizes the importance of a plentiful supply of trees, it is difficult for it to persuade the villager to see this. The villager wants wood to cook his food, and he can earn money by making charcoal or selling wood to the townsman. He is usually too lazy or too careless to plant and look after trees. So unless the government has a good system of control, or can educate the people, the forests will slowly disappear.

This does not only mean that the villagers’ sons and grandsons have 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, thus preventing it being washed away easily, but where there are no trees, the soil becomes hard and poor. The rain falls on hard ground and flows away on the surface, causing floods and carrying away the rich topsoil, in which crops grow so well. When all the topsoil is gone, nothing remains but worthless desert.

【1】It’s a great pity that ________.

A. man is only interested in building empires

B. man is eager to profit from trees

C. man hasn’t realized the importance of trees to him

D. man hasn’t found out that he has lost all trees

【2】Sooner or later the forests will disappear______

A. unless people are taught the importance of planting trees

B. unless people stop cutting down their trees

C. unless a county has a plenty supply of trees

D. unless the government punishes those who cut trees instead of planting trees

【3】The word “bind” in Paragraph 5 means”_________”

A. to make stay together B. to make wet

C. to wash away D. to improve

【4】When there is a heavy rain ,trees can help to prevent floods, as they can ___________

A. keep rain from falling down to soft ground

B. cause the soil to allow rainwater to sink in

C. prevent the soil from being washed away

D. make the topsoil stick together
