Squirrels often communicate with whistles, chirps and chucks, which sound like the word “chuck”. Whistles and chirps are like the sounds that many birds make.Now scientists have translated some of their squirrel-speak.
Hare, a professor of zoology at the University of Maniloha in Winnipeg, and his team managed to record squirrels' alarm calls.The researchers studied the sounds and then played them back to 60 wild squirrels, which the scientists approached individually with a video recorder to capture(抓拍)their reponses.Some squirrels lifted their heads up and became.Alert(警惕的).Creatures that were more frightened simply ran for their lives and dived into caves.
"In effect then, whistles that mix with chucks say 'there's an enemy of average threat that's here', and whistles without chucks say 'there's an enemy of seemingly average threat around here somewhere', while pure chirps say, 'I'm hiding here because there's an immediate danger.' " Hare told.Discovery News.
Hare and some other researchers believe such sounds arc part of an advanced language that develops just as all other communication systems.
Although squirrels risk their lives when they call out to warn others of threats, other squirrels might admire this behaviour, thus increasingly the caller’s social status, like humans who look up to heroes. Hare added that other animals, such as birds, probably understand at least some squirrel language, since they also may benefit from the alarm calls.
In fact, another Canadian study found that deep-voiced, black-capped chickadees have their own language too.According to certain research, there are a lot of tidings in chickadees' calls, such as directing fellows' activities, keeping in contact between mates, and raising alarms.
While chickadees and other birds are often welcomed into gardens by homeowners, squirrels are frequently viewed as pests(害獸). Hare wishes a greater understanding of the complex social lives and communication systems of squirrels will provide “hope that humans will gain a greater appreciation and stop doing harm to these animals”.

NASA has opened the door to the next generation of space discovery by announcing great plans for a base for humans to live on the surface of the moon forever.
The project to build a base on the moon will begin soon after 2020, with astronauts living there within four years.
The project comes after several excellent scientists and environmentalists asked humans to look beyond Earth to ensure the survival of the species (物種).
Eventually, the moon will be a base for humans to explore the solar system and one day land on Mars.
NASA began planning for the first moon landing since 1972 when George Bush, the US president, announced his new plan for space exploration four years ago.
NASA has already talked about the design of the Orion spacecraft that will replace the old space shuttle fleet in 2010.
The plan for the moon base, however, is the first detailed explanation of how NASA intends to prepare for the first manned exploration of deep space and a possible Mars mission within 30 years.
Scientists also believe that the south pole on the moon contain rich natural gases such as the rare helium-3 that could be used as fuel for the generation of nuclear power. Besides, teams of astronauts living there for six months at a time would mine for hydrogen and oxygen to make water and possibly rocket fuel.
小題1:When was the plan to explore space first announced according to the passage?
A.In 1972.B.In 1950.C.In 1968.D.In 2020.
小題2:The reasons why NASA has begun the plan to explore space include the followings except ________.
A.to protect EarthB.to explore deep space
C.to finish Mars missionD.to show how powerful the USA is
小題3:In the future, when people fly to the moon, they will probably not bring with them too much ________
A.hydrogen B.foodC.oxygenD.water
小題4:The passage mainly talks about ________.
A.the USA’s new plan for space exploration
B.how to build a base on the moon
C.why to ensure the survival of the species
D.where to get new natural resources

The south and east of the Great Lakes is famous for the huge amounts of snow it receives. When the snow starts to fall every year, people start discussing the phrase “l(fā)ake-effect snow”.
Lake-effect snow which is influenced by the movement of cold air over the relatively warm water of the Great Lakes often comes in late autumn and early winter. Because of the at least 20 degrees’ difference between the lake water and the overrunning air, it’s easy to form huge amounts of snow.
As the cool air crosses the water of Great Lakes, the lowest levels of the atmosphere begin to warm and pick up moisture. This newly warmed atmosphere is lighter than the cold air above it, so it starts rising. As the changed air continues to climb higher and higher, it finally meets much colder atmosphere which changes the moisture into water drops and ice, forming clouds. After this course repeats a number of times, the clouds become heavier and heavier, and then they are changed into snow and fall down.
The most important point that decides the amount of snowfall is the direction of the wind. If the wind runs perpendicularly(垂直地)across the lake, there won’t be plenty of time for clouds to develop. However, if the wind runs in the opposite direction, clouds will form easily. The longer the cold air travels over the lake, the more moisture it is able to produce, which leads to a greater amount of snow.
The largest amount of the lake-effect snow was found across the U.P. of Michigan, the northwestern Pennsylvania and the far southwestern and northwestern New York, which are all along the south or east of the Great Lakes. It has been over 100 inches of snowfall in a winter season.
小題1:The level of the snowfall depends on ________.
A.the size of the lake
B.the direction of the wind
C.the temperature of the lake
D.the strength of the wind
小題2:From the passage, we can learn that ________.
A.clouds are easy to produce with the help of the perpendicular wind
B.cold air always falls down and picks up moisture to form clouds
C.the temperature of the lake water is the same as the overrunning air’s above it
D.the longer journey of the cold atmosphere can make a grater amount of snow
小題3:The passage is mainly about ________.
A.the influences of the lake-effect snow for local people
B.the weight between moisture and atmosphere
C.how the phrase “l(fā)ake-effect snow” comes in New York
D.how the lake-effect snow forms around the Great Lakes

There are only about 1,000 Hawaiian monk seals(夏威夷僧海豹) left and its population is going down 4% a year. Hawaiian monk seals are found in the northwest part of the Hawaiian Islands. They spend a lot of time at sea. They are able to dive 600 feet deep, and can stay under water for up to 20 minutes. Adults grow up to seven feet long, and weigh between 400 and 600 pounds. They can live as long as 30 years.
These seals are born on land. Every year, usually in May or June, females find sandy beaches and give birth to a single baby. The female seals avoid beaches where the water becomes deep very quickly because this lets sharks swim close to land and catch the seals.
Mothers stay with their babies for six weeks. During that entire time, they do not leave the beach even to eat. Instead, they live off fat that they have stored up over the previous year and feed their babies with fat-rich milk. After six weeks, mothers go back to the sea. The young have to live on their own.
Human disturbance(打擾) has been regarded as the important factor in the decrease of the monk seals. In fact, if human come too near a mother seal too often, she will go out to the sea. Unfortunately, this usually means death for the baby. It is now against the law for people to come within 100 yards of a seal on a beach.
Recent research has shown that the decrease in the Hawaiian monk seal population is due to lack of survival of these seals at one of the most important breeding(繁殖) beaches at French Frigate Shoals. Also, seals often get trapped in fishermen and by changes in weather patterns. If these threats(威脅) were not enough, during the breeding season, males will attack females until they are badly injured or finally killed.
小題1:What can we learn about Hawaiian monk seals?
A.They are in danger of dying out.
B.They spend most of the time on the beach.
C.They are the largest animals on the Hawaiian Islands.
D.They can stay under water as long as they like.
小題2:According to the text, a seal baby______.
A.is born at sea
B.is fed on fat by the mother

D.is looked after by its mother for 6 weeks
小題3:It can be inferred from the text that______.
A.sharks are a threat to Hawaiian monk seals
B.male monk seals fight each other for females in the breeding season
C.when disturbed by people, the mother seal will protect the baby seal
D.Hawaiian monk seals give birth usually in July
小題4:What are the last two paragraphs mainly about?
A.Ways to protect Hawaiian monk seals。
B.The struggle of Hawaiian monk seals to survive.
C.The reasons for the decline(減少) of Hawaiian monk seals.
D.The influence of climate change on Hawaiian monk seals.

There is no question that teenagers need rules, which is often not a difficult thing for parents to give. What can be more challenging is giving teenagers their freedom. It can be difficult to draw the line between the two. However, some issues cannot be changed by discussion and require firm rules. For instance, rules should be established concerning driving the family car.
I will admit that I have no problem coming up with rules. To me they make life easier and they leave no room for questioning. What can be more difficult, however, is giving my teens their freedom. I guess there are really two primary reasons for this. One is that I sometimes am afraid to give them freedom. The second is that I’m not always so sure what the freedom should be.
It helps that I have a husband with whom I can discuss these problems. We talk about them, give our thoughts and then we come up with an agreement. Sometimes one of us might be more unwilling but we know that there comes a time when we really do have to learn how to let go of the reins (韁繩) a bit.
If we try to make life have nothing but rules, we are more likely to see our teen’s rebelling (反抗). They need to know that while we do have certain expectations, we also trust them to begin making their own choices and decisions. How else can they do that unless they are given the space and room to do it?
It’s really all about balance and I will be the first to admit that it can be a challenge to carry out. However, it is a necessary part of growing up. Yes, teens definitely need rules but they also need freedom.
小題1:According to the text, we can infer that the writer________.
A.refuses to give her children freedom
B.finds it difficult to make rules
C.doesn’t have a good relationship with her children
D.has trouble in giving freedom to her children
小題2:According to the writer, only rules without freedom will make the children _______.
A.strong-willedB.rebelliousC.weakD.independent
小題3:Which of the following is TRUE according to the text?
A.Rules are difficult to make for parents.
B.Rules and freedom are similarly important.
C.We should give children freedom as much as possible.
D.Rules are more important than freedom.
小題4:What does the underlined word “them” in Paragraph 3 probably refer to?
A.Problems.B.Children.C.Rules. D.Reasons.

The office has always been a place to get ahead. Unfortunately, It is also a place where a lot of natural resources start to fall behind. Take a look around next time you’re at work. See how many lights are left on when people leave. See how much paper is being wasted. How much electricity is being used to run computers that are left on. Look at how much water is being wasted in the rest-rooms. And how much solid waste is being thrown out in the rubbish cans. We bet it’s a lot.

C
Education is not an end but a means to an end.In other words, we do not educate children only for the purpose of educating them.Our purpose is to fit them for life.
In some modern countries, it has for some time been fashionable to think that by free education for all one can solve all the problems of society and build a perfect nation.But we have already seen that free education for all is not enough; we find in some countries a far larger number of people with university degrees.They refuse to do what they think “l(fā)ow” work and, in fact, work with hands is thought to be dirty and shameful in such countries.But we have only to think a moment to understand that the work of a completely uneducated farmer is far more important than that of professor.We can live without education, but we die if we have no food.If no one cleaned our streets and took the rubbish away from our houses, we should get terrible diseases.
In fact, when we say that all of us must be educated to fit us for life, it means that we must be educated in certain ways.Firstly each of us can do whatever work suited to our brains and ability.Secondly, we should realize that all jobs are necessary to society.It is very bad to be shamed of one’s work.Only such a type of education can be considered valuable to society.
小題1:What would be the best title for the text?
A.The Means of Education.B.The System of Education.
C.The Value of Education.D.The Type of Education.
小題2:From the second paragraph of the passage we know that ________.
A.work with hands is low work because it is dirty and shameful.
B.the work of the completely uneducated is the most important.
C.education is no more important than food in order to live.
D.we shouldn’t think of work with hands as low work.
小題3:What kind of educational system is valuable to society?
A.A large number of people can go to university.
B.Everyone can solve all the problems of society.
C.All the people can get free education.
D.Everyone must be educated differently to fit them for society.
小題4:What can be inferred from the passage?
A.Our society needs all kinds of jobs.
B.Free education for all is enough.
C.A farmer is more important than a professor.
D.People with university degrees shouldn’t do low work.
