The Pine Street Foundation conducted its research on the belief that cancer cells give off a different type of metabolic(新陈代谢) waste product than normal cells. According to the study, the difference is so great that it can be detected by a dog’s sense of smell, including both early and late stages of the disease.
In the conclusion of the study the Pine Street Foundation said that even ordinary dogs may be trained to identify the presence of cancer with only a breath sample. The organization also said that dogs can recognize the disease with astonishing amount accuracy and, finally, that the dog’s detection was not hindered(妨碍) by the presence of age, smoking or stage of cancer.
The Pine Street Foundation plans to continue their research and is currently seeking funding to launch new studies.

The town was there first. Two Roman roads crossed there, and there are signs of building before Roman times (earlier than A.D. 43). Cambridge became a center of learning, and the authority of the head of the university was recognized by the king in 1226.
With about 8,250 undergraduates and over2,000 postgraduates, the city is a busy place in “full term” .Undergraduates are not allowed to keep cars in Cambridge, so nearly all of them use bicycles. Don’t try to drive through Cambridge during the five minutes between lectures. Your bicycle must go through a boiling sea of other bicycles hurrying in all directions, if you are in Cambridge at five minutes to the hour any morning of full term, you know that you are in a university town.
小题1:What is called a university town?
A. A town with a university in it
B. B. A university with a town in it.

小题2:How many students does Cambridge have?
A.Eight thousand, two hundred and fifty. | B.Two thousand. |
C.Ten thousand. | D.More than ten thousand. |

A.Cambridge—A University Town. | B.Cambridge – A Centre of Learning |
C.Cambridge with Many Students. | D.Cambridge with a Long History |
A professor’s teaching method is another factor that determines the degree and type of student participation. Some professors prefer to control discussions while others prefer to guide the class without controlling it. Many professors encourage students to question their ideas. Students who object to the professor’s point of view should be prepared to prove their positions.
In the teaching of science and mathematics, the controlling mode of instruction is generally traditional, with teachers presenting formal lectures and students taking notes. However, new educational trends have turned up in the humanities and social sciences in the past twenty years. Students in education, society, and history classes, for example, are often required to solve problems in groups, design projects, make presentations, and examine case studies. Since some college or university courses are “practical” rather than theoretical, they pay more attention to “doing” for themselves.
小题1:“Participation in the classroom is not only accepted but also expected of the student” in ____
class.
A.the humanities and social sciences | B.the science and mathematics |
C.the theoretical lessons | D.the strictly controlled courses |
A.has not changed much in the past twenty years |
B.pay attention to students’ studying instead of teachers’ teaching |
C.is much more important than that of science and mathematics |
D.has become more practical than theoretical. |
A.these professors are often not well prepared before class |
B.these professors want to stress “doing” |
C.these professors want to test the students abilities |
D.these professors are not willing to teach theory |
A.Student participation is not common in many courses like society and history classes. |
B.Some professors want to control the classroom discussion. |
C.Some of students are wanted to attend the lecture of science and mathematics. |
D.New educational trends have turned up in the teaching of natural sciences such as |
Until now the only information about the behavior of the creatures which measure up to 18 meters (59 feet) in length has been based on dead or dying squid washed up on shore or captured②in commercial fishing nets.
But Tsunemi Kubodera, of the National Science Museum, and Kyoichi Mori of the Ogasawara Whale Watching Association, both in Tokyo have captured the first images of Architeuthis attacking bait③900 meters below the surface in the cold, dark waters of the North Pacific. “We show the first wild images of a giant squid in its natural environment,” they said in a report in the journal Proceedings B of the Royal Society.
Little is known about the creatures because it has been so difficult to locate and study them alive. Large ships and specialist equipment, which is costly, are needed to study deep sea environments.
The Japanese scientists found the squid by following sperm whales, the most effective hunters of giant squid, as they gathered to feed between September and December in the deep waters off the coast of the Ogasawara Islands in the North Pacific. They used a remote long-line camera and depth logging system to capture the giant squid in the ocean depths.
The most dramatic character of giant squids is the pair of extremely long tentacles④, distinct from the eight shorter arms. The long tentacles make up to two-thirds of the length of the dead specimens⑤to date. The giant squid appear to be a much more active meat-eating animals than researchers had thought.
Notes:
① squid n. 鱿鱼
② capture vt. 捕获
① bait n. 鱼饵
② tentacle n. 触角,触须
③ specimen n. 标本,样本

C.They like playing, using their tentacles. |
D.They have only eight arms around the mouth. |
A.through a remote long-line camera |
B.by using depth logging system |
C.by following sperm whales |
D.by using the bait to attract them |
First, it’s possible that the animals may have heard the quake before the tsunami hit. The underwater rupture likely produced sound waves known as infrasound② or infrasonic sound. Humans can’t hear infrasound, but many animals including dogs, elephants, tigers and pigeons can.
A second early warning sign the animals might have sensed is ground vibration③. The massive quake would have produced vibrational waves known as Rayleigh waves. These vibrations move through the ground like waves move on the surface of the ocean but faster. They travel at ten times the speed of sound. The Rayleigh waves would have reached SriLanka hours before the water hit. Mammals, birds, insects and spiders can sense Rayleigh waves. So the animals at Yale might have felt the Rayleigh waves and then run to higher ground.
But what about humans? While we can’t hear infrasound, we can feel it, although we don’t necessarily know we’re feeling it. We also experience Rayleigh waves by special sensors in our joints, which exist just for that purpose. Sadly, it seems we don’t pay attention to the information when we get it. Maybe we screen it out because there’s so much going on before our eyes and in our ears. Humans have a lot of things on our minds and usually that works out OK.
Notes:
① tsunami n. 海啸
② infrasound n. 次声
③ vibration n. 振动,颤动
Choose the best answers according to the above:
小题1: Why did few animals at Yala die when the tsunamis that caused a huge number of human deaths hit?
A.Because the animals were staying at a higher place in the park. |
B.Because the animals were able to run much faster than human beings. |
C.Because human beings cannot hear the infrasonic sound. |
D.Because the animals might have picked up the danger signals and ran away. |
A.Rayleigh waves are massive vibrational waves that usually cause quakes or tsunamis. |
B.Rayleigh waves move on the ocean surface at a speed ten times that of sound waves. |
C.Rayleigh waves can be felt both by animals and human beings. |
D.Rayleigh waves, just like infrasonic sound, can only be felt by animals. |
A.we can’t feel the infrasound so we can’t be informed of the danger |
B.we can feel Rayleigh waves as well as infrasound so we are able to escape the danger like animals |
C.we were so busy with things on our minds that we feel neither infrasound nor Rayleigh waves |
D.we think nothing of the information of its coming even though we can also get it |
A.Screening out the information. |
B.There being so much going on before our eyes and in our ears. |
C.Having a lot of things on our minds. |
D.Paying attention to the information. |
Dennis Burdens, who wrote an article, tells us that he once saw a UFO himself. He was having dinner one night with a friend near Tripoli, Libya, and after dinner the two men walked across a yard to his room to look at some papers. Burdens noticed that the moon looked strange that night.
“It wasn’t the moon ”, was the reply.
They watched the light and saw that it was moving. It seemed to be an object rather like a big plate. In some ways it looked like smoke with a light on it, but it wasn’t smoke because it didn’t change its shape. It was moving in a regular way. That is to say, it didn’t go suddenly faster or more slowly, and it didn’t go higher or lower. So the two men decided that there must be men in it.
After that, Burdens said that he felt eyes looking at him. He was being watched in the darkness.
When it was nearer, they noticed that the bottom parts were brighter than the top. The bottom was yellow and the top red. Then the object suddenly turned away and left Libya, moving very fast.
On a later day Burdens talked to other people about it, and he found some who had seen it. They all described it in the same way. Could they all be mistaken?
小题1: UFOs are _____.

A.when they were walking across a yard to Burdens’ room |
B.while they were looking at the light |
C.when Burdens noticed the moon appearing strange |
D.while they were having dinner |
A.regularly | B.in a changeable way | C.slowly | D.fast |
A.smoke | B.a large plate | C.light | D.a jumping object |
A.by Burdens and his friend | B.brighter in the darkness |
