Sixty-five million years ago, an asteroid (小行星) that crashed on Earth led to the disappearance of the largest animals that have ever walked our planet – the dinosaurs. At least, this is what some scientists believe. But that accident happened so long ago. People have come to believe that we are free of threats from asteroids and everything else from space.
However, what happened on Feb 15 , 2013 was a reminder that we’re just as vulnerable as the dinosaurs once were. Two objects from space – a meteor (陨石) and an asteroid called 2012 DA14 – visited Earth’s atmosphere on the same day. The former fell in Russia, injuring 1,200 people, while the latter passed by Earth at a record-setting close distance.
Scientists had been expecting the asteroid since last year, but the meteor was a surprise. NASA’s telescope system only detects asteroids at least 50 meters in diameter (直径), which is just about the size of 2012 DA14. But the meteor was much smaller, which made it harder to spot.
But what if we do spot an asteroid that is headed right for Earth? There are several possible ways in which dangerous asteroids could be made to change its orbit. Which method is best depends on several factors and most importantly – how much time we have to stop it.
If there is enough time before the hit, we can send off a heavy spacecraft to travel alongside the asteroid. The gravity from the spacecraft would gradually change the rock’s orbit. Besides that, scientists could one day use sun-powered lasers to either make asteroids disappear or change their course. If there’s not enough time, we’ll have to go after the asteroid with a spacecraft and change its orbit with a crash. Finally, if things are truly desperate, there will be only one choice left – to use a nuclear bomb. That could turn the asteroid into a meteor shower, which would be even more dangerous.The author mentioned the asteroid that led to the dinosaurs’ dying out to ______.

It was a winter morning， just a couple of weeks before Christmas 2005. While most people were warming up their cars， Trevor， my husband， had to get up early to ride his bike four kilometers away from home to work. On arrival， he parked his bike outside the back door as he usually does. After putting in 10 hours of labor， he returned to find his bike gone.
The bike， a black Kona 18 speed， was our only transport. Trevor used it to get to work， putting in 60-hour weeks to support his young family. And the bike was also used to get groceries （食品杂货）， saving us from having to walk along long distances from where we live.
I was so sad that someone would steal our bike that I wrote to the newspaper and told them our story. Shortly after that， several people in our area offered to help. One wonderful stranger even bought a bike， then called my husband to pick it up. Once again my husband had a way to get to and from his job. It really is an honor that a complete stranger would go out of their way for someone they have never met before.
People say that a smile can be passed from one person to another， but acts of kindness from strangers are even more so. This experience has had a spreading effect in our lives because it strengthened our faith in humanity （人性） as a whole. And it has influenced us to be more mindful of ways we， too， can share with others. No matter how big or how small， an act of kindness shows that someone cares. And the results can be everlasting.

Trees are useful to man in three important ways: they give him wood and other useful things, they give him cool places, and they help to stop drought and flood.
Unluckily, in many parts of the world, man has not found that the third of these points is the most important. Man wants to make money from trees, so he has cut them down in large numbers, only to find that without them he has lost the best friends he had. And also, he is usually too careless to plant and look after new trees. So the forests slowly disappear.
This does not only mean that man will have fewer trees. The results are even worse: for where there are trees, their roots break up soil-make the rain in-and also bind the soil, thus stopping it from being washed away easily; but where there are no trees, the rain falls on hard ground and flows away, causing floods and carrying away the rich top-soil. When all the top-soil is gone, nothing is left but useless desert.
1.The most important points of trees to man is ________.

“How can I learn English well?” This is a question many students ask. In my opinion, the most effective way is to learn lessons by heart. If you can recite the text and write it out, you’ve learned it fairly well. And if you can tell, in your own words, what the lesson says you’re a very successful learner indeed. Your English will be quite perfect.
This is a difficult task. However, if you try to learn by heart only part of each lesson, you’ll find it not half so hard as you might have thought.
Learning this way, you will make rapid progress. Of course, writing is also necessary. It helps you a lot on our way to success in English.
Equally important is to feel the language. You should be able to laugh at jokes and be shocked at bad news. When using English, try to forget your mother tongue. Instead of helping you, your own language gets in your way. So, never try to see English through translation.
1.In the writer’s opinion, the most effective way in learning English is ____.
A. to practise speaking, writing and feeling it
B. to forget your own native language
C. to translate everything into his own language
D. to memorize the English words and grammatical rules
2. “Instead of helping you, your own language gets in your way.”This sentence means that memorizing your own language can ________.
A. help you to study English well B. stop you mastering English
C. make English easy to learn D. help you notice mistakes
3.Equally important is to feel the language. “to feel the language” here means_____.
A. to get a knowledge of English by touching
B. to be able to read and write English
C. to translate English into your own by imagining
D. to be able to experience the rich sensation of the language
B
One of the main challenges facing many countries is how to maintain their identity in the face of globalization and the growing multi-language trend. “One of the main reasons for economic failure in many African countries is the fact that, with a few important exceptions, mother-tongue education is not practiced in any of the independent African states.” said Neville Alexander, Director of the Project for the Study of Alternative Education in South Africa at the University of Cape Town.
In response to the spread of English and the increased multi-language trends arising from immigration, many countries have introduced language laws in the last decade. In some, the use of languages other than the national language is banned in public spaces such as advertising posters. One of the first such legal provisions was the 1994 “Toubon law” in France, and the idea has been copied in many countries since then. Such efforts to govern language use are often considered as futile by language experts, who are well aware of the difficulty in controlling fashions in speech and know from research that language switching among bilinguals is a natural process.
It is especially difficult for native speakers of English to understand the desire to maintain the “purity” of a language by law. Since the time of Shakespeare, English has continually absorbed foreign words into its own language. English is one of the most mixed and rapidly changing languages in the world. But that has not been a barrier to acquiring superiority and power. Another reason for the failure of many native English speakers to understand the role of state regulation is that it has never been the Anglo-Saxon way of doing things. English has never had a state-controlled authority for the language, similar, for example, to the Academic Francaise in France.
The need to protect national languages is, for most western Europeans, a recent phenomenon- especially the need to ensure that English does not unnecessarily take over too many fields. Public communication, education and new ways of communication promoted by technology, may be key fields to defend.

B. They want their language to spread to other countries.
C. They have a long history of taking words from other languages.
D. It reduces economic development of the countries in Europe.
4. The best title for the passage is “ ”.
A. Fighting against the rule of English
B. Globalization and multi-language trends
C. Protecting local languages and identities
D. Ensuring the change of language by law
Stopping teens from smoking is a big challenge many communities face today. Many communities can only watch without being able to act while local businesses continue to sell tobacco products to children, even under the risk of punishment by law.
Recent studies show that a large percentage of teens today are getting their cigarettes from stores, mostly gas stations or convenience stores. As teens continue to be able to buy their own cigarettes, more and more communities begin to punish those who sell cigarettes to the teens.
One community has experienced success in their attempts to stop the sale of tobacco products to children. Woodridge, Illinois, started a program seven years ago which forbade and strictly punished the sale of tobacco products to children. The entire program includes local licensing of vendors (小贩), repeated undercover inspections to see if the sale to children has stopped, and education programs in schools. Woodridge has become a model community as other communities are moving to stop teen tobacco use.
A recent national study showed that 36.5% of females, and 40.8% of males buy their cigarettes from stores, whether it is a gas station or a supermarket. Hopefully, as more and more sellers see the trouble they face if caught selling to children, they will stop selling.
True, tightening down on stores that sell tobacco to children isn’t going to completely stop the problem of teen tobacco use. Teens continue to get them from other sources. But it definitely does prevent their efforts. With more education in schools, and perhaps stronger punishments for teens caught with tobacco, more and more teens will see the problems with the tobacco usage, and will stop the habit.
1. To stop teens from smoking, more and more communities are ________.
A. punishing those who sell cigarettes to teens more severely
B. punishing teens caught with tobacco more severely
C. educating those who sell cigarettes about the danger of teen smoking
D. stopping the sale of tobacco products in stores
2. Which of the following is NOT a way Woodridge uses to stop tobacco sale to children?
A. Local licensing to tobacco sale. B. Repeated undercover inspections.
C. Education programs in schools. D. Stronger punishment of teens caught smoking.
3. It can be inferred from the passage that _____________.
A. teens can only buy cigarettes from gas stations and convenience stores
B. more communities have succeeded in stopping teen tobacco use
C. More males than females have the habit of smoking in America
D. Punishment alone cannot solve the problem of teen tobacco use
4. What attitude does the writer have towards stopping teen tobacco abuse?
A. Negative B. Optimistic C. Uncertain D. Uncaring
