Everyone makes mistakes in life, but for whales and dolphins, the “mistake” of landing on the shore costs the highest price---their lives.
People living along the coast of Australia and New Zealand have been shocked and saddened by the number of whales and dolphins that they have found on their beaches recently. Since November 28th, 96 whales and dolphins have died in Australia and 53 whales died in New Zealand. Although 20 whales were saved, some of these were not expected to live, as they were too weak to swim with the others back to sea.
Bob Brown, leader of Australia’s Green party, said the mass beaching was caused by the recent “sound bombing” of the ocean floor between the two countries. This is a method of testing for oil and gas reserves (储藏量).
But mass beaching of whales has long puzzled scientists. Typically most members of the stranded (搁浅) group will appear to be perfectly healthy. “Some researchers believe that close relationship within the group causes the problem, if one gets into trouble, the others will not leave” said Shery Gibney, a leading biologist in New Zealand. “Some will come in and try and assist it; if they get trapped on the beach, then more will come.”
Another common theory is that the whales’ navigation (导航) system are thought to break down in some way. It has been said that whales follow electromagnetic (电磁的) patterns in the sea-bed. The whales can get confused because these patterns sometimes change. That would be a bit like a new roundabout (环状交叉路) being built on a road you were used to driving on. You might be confused for a minute when you come to it for the first time, and you might even take a wrong turning before getting back on your route.
A different idea is that when whales chase fish for food they end up in shallow waters because they are not paying attention to where they are going.
And yet, from time to time a group will swim on purpose into shallow waters and end up on the beach, where they die. If returned to the sea, some whales often show great determination in restraining themselves.
________ whales and dolphins would probably die in this mass beaching along the coast of Australia and New Zealand.
A. Less than 100 B. Less than 150 C. More than 150 D. 149
Which of the following can be used to explain the term “sound bombing”?
A. The terrible sound that is caused in the war between two countries.
B. Human activities that aim to explore the ocean floor.
C. The loud sound that whales and dolphins make.
D. The earthquakes that happen on the ocean floor.
Which of the following couldn’t probably lead to the mass beaching of whales?
A. A change in the electromagnetic patterns that whales follow.
B. New roundabout being built on a road.
C. Their full attention to the search for food.
D. Exploiting natural resources in oceans.
The passage is mainly about _______.
A. that whales and dolphins may make mistakes as well as human beings
B. how scientists have found the reasons for the mass beaching of whales
C. how human beings make use of the ocean resources
D. why the mass beaching of whales happens

WASHINGTON --- It’s a great achievement that inspires concepts of robots with consciousness and independent minds.
When people or animals get hurt, they can usually compensate for minor injuries and keep limping along, but for robots, even slight damage can make them stumble and fall. However, a recently made robot has demonstrated a new ability: it can heal its own damage.
The new robot, which looks like a splay-legged (弓形腿的), four-footed starfish, can sense injury to itself and adapt. That ability sets the new robot apart from earlier machines. Because the robot can recover from unfamiliar places.
“There is a need for planetary robotic rovers (行星机器探测车) to be able to fix things on their own,” says Josh Bongard, a professor in the Univer
sity of Vermont, who is one of the device’s creator. “Robots on other planets must be able to continue their mission without human help if they are damaged and cannot communicate their problem back to Earth.”
A typical robot functions according to a computer program, but the new robot works differently. First, sensors in its four legs observe the robot’s movements and signals to its built-in computer. From the information it collects, the robot creates its own programs that allow it to adapt to different situations. For example, when the researchers shortened one of the robot’s legs, the smart machine simply adjusted its way of walking—it used three legs instead of four.
The researchers are looking for other places to put the resilient robot to work. One spot is the ocean floor. That dark and dangerous undersea area might be a good choice for a robot that the scientists call the Starfish. “We never officially named the robot, but we usually refer to it as the Starfish, even though a real starfish has five rather than four legs,” says Bongard. “Also, a real starfish is much better than our robot at recovering from injury, because it can actually grow its legs again.” Scientists have created robots that help humans in many ways: by exploring space, fighting fires, and even performing s
urgery.
【小题1】The newly designed robot distinguishes itself from the former ones because it________.
| A．can communicate with people on the earth about their problems |

Due to climate change, Arctic ice is breaking up earlier in the spring, and its area is decreasing. This is creating problems for polar bears that make their homes off northern Alaska and in Hudson Bay.
Polar bears off Alaska normally hunt and raise their young on ice sheets that float on the ocean. But as the ice has melted, the polar bears have been forced to spend more time on land. There, they have begun to frequent beaches, feeding on the remains of whales caught by native hunters. For polar bears, this food is less nutritious than seals that they normally catch on ice sheets. The shrinking（减少） ice has also forced more polar bears into the ocean. In the past, they only had to swim short distances between ice sheets. But as the ice has shrunk, polar bears have been forced to swim longer and longer distances in the open ocean. This poses a severe danger during rough weather, and an increasing number of drowned polar bears have been observed.
In Hudson Bay, the ice breaks up three weeks earlier in the spring now than it did 20 years ago. Polar bears on Hudson Bay fast（绝食） during the summer, waiting for ice to form in the fall to hunt. Every year, the summer gets longer, and the bears get skinnier. Over the past 25 years, the average weight of the female bears has dropped 68 kg. This loss affects their ability to reproduce, and already the number of births has dropped 15 percent. Unless the bears can learn to survive these climate changes, these giants of the ice may one day disappear.
1.What is Arctic ice doing earlier each year?
|
A．It’s freezing. |
B．It’s hardening. |
|
C．It’s melting. |
D．It’s expanding. |
2.What is true of polar bears that are spending more time on land in Alaska?
|
A．Their young are dying. |
|
B．Their diet is changing. |
|
C．Their health is improving. |
|
D．Their families are growing. |
3.What do polar bears in Hudson Bay do during the summer?
|
A．They claim territory(地域). |
B．They protect mates. |
|
C．They hunt animals. |
D．They stop feeding |
4.In which publication would you most likely find this passage?
|
A．Medical News |
B．Society Today |
C．Wildlife Journal |
D．Design Magazine |

Weddings in the United States vary as much as the people do. There are church weddings with a great deal of fanfare； there are weddings on mountain-tops with guests barefooted； and there have been weddings on the ocean floor with oxygen tanks for the guests. But many weddings, no matter where or how they are performed, include certain traditional customs.
Before a couple is married，they become engaged. And then invitations are sent to those who live nearby, their close friends and their relatives who live far away. When everything is ready，then comes the most exciting moment.
The wedding itself usually lasts between 20 and 40 minutes. The wedding party enters the church while the wedding march is played. The bride carrying a bouquet enters last with her father who will "give her away". The groom enters the church from a side door. When the wedding party is gathered by the altar， the bride and groom exchange vows. It is traditional to use the words "To have and to hold from this day forward， for better， for worse， for richer， for poorer， in sickness and in health， to love and to cherish， till death do us part". Following the vows， the couple exchange rings. Wearing the wedding ring on the fourth finger of the left hand is an old custom.
After the ceremony there is often a party, called a "reception" which gives the wedding guests an opportunity to congratulate the newlyweds.
The car in which the couple leaves the church is decorated with balloons, streamers and shaving cream. The words "Just Married" are painted on the trunk or back window. The bride and groom run to the car under a shower of rice thrown by the wedding guests.

The journey two divers made some time ago to the deepest point on the earth makes us realize how much of the world still remains to be studied. The two men went down seven miles to the bottom of the Pacific Ocean inside a small steel ball to find out if there are any ocean currents(水流) or signs of life.
It was necessary to set out early, so that the ball would come to the surface in daylight, and be easily found by the mother ship which would be waiting for it. The divers began preparations early in the morning and soon afterwards, when all was ready, the steel ball disappeared under the surface of the water.
The divers felt as if they were going down steps as they passed through warm and cold layers (层) of water. In time the temperature dropped to the freezing point. They kept in touch with the mother ship by telephone telling how they felt. Then, at a depth of 3,000 feet, the telephone stopped working and they were quite cut off from the outside world. All went well until some four hours later at 30,000 feet, the men were frightened by a loud, cracking noise. Even the smallest hole in the ball would have meant instant death. Luckily, though, it was only one of the outer windows that had broken. Soon afterwards, the ball touched the soft ocean floor raising a big cloud of "dust" made up of small dead sea creatures. Here, powerful lights lit up the dark water and the men were surprised to see fish swimming just above them quite untroubled by the great water pressure. But they did not dare to leave the lights on for long, as the heat from them made the water boil. Quite unexpectedly, the telephone began working again and the faint but clear voices of the divers were heard on the mother ship seven miles away. After a stay of thirty minutes the men began their journey up, arriving three hours later, cold and wet through, but none was worse for their experience.
65. The purpose of the divers' journey to the deepest point on the earth was to find
A. if there are water currents, and life in the great depths
B. if people can stand the severe cold in the great depths
C. if there are steps in the great depths
D. if the telephone works well in the great depths
66. The divers set out early in the morning so that .
A. they could return to the surface during the day
B. they could see at the bottom of the ocean
C. they could avoid the cold at night
D. they could stay long at the bottom
67. As the divers went down to the ocean floor, the telephone .
A. kept working all the time
B. stopped working at a depth of 3,000 feet and began working again after they reached the bottom
C. stopped working at a depth of 3,000 feet and began working again at 30,000 feet
D. stopped working at a depth of 3,000 feet and began working again when they returned to the same depth
68. On the ocean floor, the divers found that .
A. there was no life but some small dead sea creatures
