题目内容
Whale beachings（搁浅）_______ be caused by factors such as illness, or disorientation（迷失方向）caused by extra noise in the oceans, ______ shipping or oil and gas drilling.
- A.might; from
- B.will; by
- C.should; in
- D.shall; on
试题分析：考察情态动词。本题第一空might也许；will将要；should应该；shall将要；句意：鲸鱼搁浅也许是由多种因素导致的，如疾病或者海洋里的噪音导致的迷失方向或者来自石油钻探。句中的from表示原因。第一空的might也许，表示不确定的原因，因为后面提出了多个具体的解释。故A正确。
考点：考察情态动词
点评：英语中有不少情态动词都可以表示推测，其语气有强有弱，表示的可能性有大有小，现将它们的用法归纳如下：1. 接近100%的可能，只有must才具有这么高的可能性，它的意思是“一定”“肯定”，所作出的推测几乎接近事实。如：He must be coming by bus. 他一定是乘公共汽车来。2. 很有可能，表示可能性较大的情态动词主要有may, should, ought to，它们大致相当于汉语的“可能”“应该”“按理会”。 3. 一般性的可能，在所有表示推测的情态动词中，might和could所表示的可能性最小，由于它们的语气较委婉，较不确定，所以往往相当于汉语的“可能”“也许”“说不定”等。4. 理论上的可能性，表示理论上的可能通常是用can，且可以用于肯定句中。
A. the; the B. a; a C. a; the D. the; aEars are for hearing — everyone knows that. But for a creature called the Cuvier’s beaked whale, hearing starts in the throat (喉咙), a new study found.
The observation might help explain how all whales hear. The work might also help scientists understand how animals are affected by underwater sonar (声呐). This sonar, used by some ships, sends out sound waves to locate underwater objects.
The Cuvier’s beaked whale is a so-called toothed whale. Toothed whales dive deep into the ocean in search of food. As the whales hunt, they produce sounds that reach objects and then return to the whales. This allows the animals to “see” the shape, size, and location of objects, even when they’re 1,000 meters under the sea, where it is totally dark.
To better understand how the whale hears, researchers from San Diego State University in California took X rays of two Cuvier’s beaked whales. The whales had died and washed up on the beach.
Ted Cranford and his colleagues used the images to make a computer model of a Cuvier’s b
eaked whale’s head. Then, they modeled the process of sound traveling through the head.
The researchers knew that some sounds get to the ears of a toothed whale through a structure (构造) called “the window for sound”. Found on the lower jaw, this structure is very thin on the outside and has a large pad (垫) of fat on the inside.
When the researchers used their computer model to work out how sound waves travel in the whale’s head, they were surprised to find that sounds coming from right in front of the whale actually travel under the animal’s jaw. From there, sound waves move through the throat, into a hole in the back of the jaw, and finally to the pad of fat near the animal’s ears.
【小题1】Toothed whales look for food under the sea by ______.
| A．watching the shape and size of their objects | B．diving deep into the sea |
| C．sending and receiving sounds | D．making lots of noises |
| A．find out why they had died and washed up on the beach |
| B．make a computer model of a Cuvier’s beaked whale’s head |
| C．make sure that sound travels through the head |
| D．know more about the way the whale hears |
| A．A hole in the back of the jaw → the ears → the jaw → the throat. |
| B．The jaw → the throat → a hole in the back of the jaw → the ears. |
| C．The throat → the jaw → the ears → a hole in the back of the jaw. |
| D．The ears → the throat → a hole in the back of the jaw → the jaw. |
| A．The throat is important to the Cuvier’s beaked whale’s hearing. |
| B．Ships send out sound waves like a Cuvier’s beaked whale. |
| C．The ears are actually useless to the Cuvier’s beaked whale. |
| D．The researchers haven’t found how the whales hear. |
The Pacific island nation of Nauru used to be a beautiful place. Now it is an ecological disaster area. Nauru’s heartbreaking story could have one good consequence — other countries might learn from its mistakes.
For thousands of years, Polynesian people lived on the remote island of Nauru, far from western civilization. The first European to arrive was John Fearn in 1798. He was the British captain of the Hunter, a whaling ship. He called the island Pleasant Island.
However, because it was very remote, Nauru had little communication with Europeans at first. The whaling ships and other traders began to visit, bringing guns and alcohol. These elements destroyed the social balance of the twelve family groups on the island. A ten-year civil war started, which reduced the population from 1,400 to 900.
Nauru’s real troubles began in 1899 when a British mining company discovered phosphate (磷酸盐)on the island. In fact, it found that the island of Nauru was nearly all phosphate, which is a very important fertilizer for farming. The company began mining the phosphate.
A phosphate mine is not a hole in the ground; it is a strip mine. When a company strip-mines, it removes the top layer of soil. Then it takes away the material it wants. Strip mining totally destroys the land. Gradually, the lovely island of Nauru started to look like the moon.
In 1968, Nauru became one of the richest countries in the world. Every year the government received millions and millions of dollars for its phosphate.
Unfortunately, the leaders invested the money unwisely and lost millions of dollars. In addition, they used millions more dollars for personal expenses. Soon people realized that they had a terrible problem — their phosphate was running out. Ninety percent of their island was destroyed and they had nothing. By 2000, Nauru was financially ruined. Experts say that it would take approximately $433,600,000 and more than 20 years to repair the island. This will probably never happen.
【小题1】What might be the author’s purpose in writing the text?________.
| A．To seek help for Nauru’s problems. |
| B．To give a warning to other countries |
| C．To show the importance of money |
| D．To tell a heartbreaking story of a war. |
| A．Rich and powerful | B．Modern and open |
| C．Peaceful and attractive | D．Greedy and aggressive |
| A．soil pollution | B．phosphate overmining |
| C．farming activity | D．whale hunting |
| A．Its leaders misused the money |
| B．It spent too much repairing the island |
| C．Its phosphate mining cost much money |
| D．It lost millions of dollars in the civil war. |
| A．The phosphate mines were destroyed |
| B．The ecological damage is difficult to repair. |
| C．The island was abandoned by the Nauruans |
| D．The leaders will take the experts’ words seriously. |
