Dangers from Outer Space

What is the greatest threat to life on our planet? Is it climate change? Shortages of food or water? Or might an altogether bigger danger come from somewhere further away: space?

We’re not talking about an attack by little green men here. Instead, how about being hit by a large falling star, beat by deadly universal rays or fried by the energy of an erupting star?

It wouldn’t be the first time that our Earth has had a rough ride over the last 3.7 billion years, with some disastrous events. The most famous mass extinction(灭绝)was 66 million years ago, when it’s widely believed that a meteorite(陨石)killed off the dinosaurs. A 110-mile-wide crater in Mexico with the same geological age supports this theory.

Believe it or not, this wasn’t the worst catastrophe in our planet’s history. That was when 96% of life was wiped out at the end of the Permian period, 252 million year ago. Scientists don’t know for sure why this happened, but any potential explanations carry with them the possibility that similar events could happen again.

Some experts believe that our Sun has a twin star which is too far away to observe directly. This huge sleeping star could twist the paths of orbiting icy rocks and cast them towards the rest of the Solar System.

Is this what happened 252 million years ago? Or is there instead, perhaps, a distant, ninth plant in our Solar System which pulls in passing comets(彗星)and sends them dashing our way?

The Sun that has given us the warmth is gradually turning into a deadly enemy. Like all stars, it is slowing dying, burning through its energy supplies. As it does so, it expands, and in about 2 billion years it will have grown so much that the heat will make life on planet Earth unbearable.

While all this sounds a little horrible, take comfort from the fact that the chance of being hit by a huge interstellar projectile(星际碰撞物)is unbelievably slim, and that 2 billion years is a very long time.

A. 3.7 billion years ago. B. 252 million years ago.

2.Why was 96% of life destroyed at the end of the Permian period?

A. The cause is still unknown.

B. A huge falling star hit the earth.

A. All stars will eventually run of energy.

B. Our planet will be attacked by little green men.

C. We will be fried by the energy of an erupting star.

D. A huge sleeping star will hit the earth in millions of years.

4.What is the author’s attitude toward the dangers from outer space?

A. Frightened. B. Relieved.

C. Worried. D. Doubtful.

My students often tell me they don’t have “enough time” to do all their schoolwork. My reply is often brief—You have as much time as the president. I usually carry on a bit about there being 24 hours in the day for everyone, and suggest that “not enough time” is not an acceptable explanation of not getting something done.

Once in graduate school, I tried to excuse myself to one of my professors by saying that I was working hard. His answer to me was, “That’s irrelevant. What’s important is the quality of your work.” Since then I have had time to think about the “hard worker” dodge (伎俩), and I have come to some conclusions — all relevant to the issue of how much time we have.

If you analyze(分析) the matter, you can identify(确定) two parts of the problem: There is, of course, the matter of “time”, which we can think of as fixed. Then there is the problem of “work” during that time. But, as my professor suggested, it’s not how hard one works but the quality of the product that is important.

That led me to a new idea: the quality of the work. That concept is perhaps best explained by a sign I once saw on the wall in someone’s office---Don’t work harder but work smarter. There’s a lot of sense in that idea.

If you can’t get more time, and few of us can, the only solution(解决方法) is to improve the quality of the work. That means thinking of ways to get more out of the same time than we might otherwise get. That should lead us to an analysis of our work habits. Since “work” for students usually means “homework”, the expression “work habits” should be read as “study habits”.

Then, as a smart student, you will seek to improve those skills that you use in study, chiefly reading and writing. If you learn to read better and write better, there are big benefits that pay off in all your studies.

Exams appeared long time ago and it is a way of picking out excellent ones .All taking exams want to win. So exam cheatings always go hand in hand. Taking exams in a large group setting can be stressful for students and for the staff members who are watching over them. When classrooms are crowded and desks are close together, cheating might be tempting.

Many organizations took measures to stop cheating. Not long ago one university in Thailand came up with an anti-cheating hat that makes it almost impossible for students to see other students’ papers. The hats were made by stapling two pieces of paper onto a headband, one to each side of the head.

This caused many students annoyed. A photo of the students wearing the anti-cheating hats made its way to the internet, and the university was also criticized for making students wear those ridiculous looking homemade hats.

After being criticized, senior academic staff at Kasetsart University in Bangkok, Thailand, released a statement saying that the hats idea came from students. They said that in a bid to prevent cheating they asked the students for ideas on how to prevent cheating in the upcoming  exam, which was being taken by almost one hundred students. Students came up with different ideas, then the paper hat idea was selected by them as the most fit. The university claims that no-one was forced to use the hat, but they all chose to do so. “When wearing the hat during the exam, students felt more relaxed,” a lecturer at the university ,Nattadon Rungruangkitkrai, said. “It was not meant to indicate that Kasetsart students often cheat on exams. I apologize if the photo makes other people look at my students in a negative way,’ Rungruangkitkrai added.
