A volcanic eruption in Iceland has sent ash across northern Europe. Airlines have stopped or changed the flights across the Atlantic Ocean, leaving hundreds of passengers stuck in airports.  

Grirmsvom is one of the largest and most active volcanoes in Europe. What makes Grimsvom different is that it lies under a huge glacier（冰川） of ice up to 12 maters thick. The hot volcano heats up the ice above it, which then forms a layer（层）of water between the glacier and the volcano This layer of water puts pressure on the volcano, keeping it stable, As the water flows out from under the glacier, the pressure lifts. The lava（岩浆） from the volcano then comes up to the surface. This is exactly what happened today.  

Now, airlines have to make changes to their flights so as not to fly through the clouds of volcanic ash. According to KLM. one of Europe’s biggest airlines, airplanes cannot go under the cloud or over it. Going through the cloud can result in ash getting stuck in the airplane’s engines, causing damage to the plane.  

The eruption has also caused problems for animals in Iceland. The volcano left ash and sharp. Glass-like rocks all over the countryside. Farmers are keeping their animals inside to stop them from eating ash- covered grass to the sharp object.

 Eat healthier. Exercise twice a week. Read more books. Lose weight. We make the same resolutions(决心) every year, but most of us fail, dying out after only a few days or , at best, weeks. Even the most successful among us crash and burn when it comes to personal change. President-elect Barack Obama struggles to remove his cigarette habit.
Professionals who help people make changes in their lives suggest the change is determined not by one's surroundings, but one's mind. Beginning with small goals or steps usually leads to a bigger payoff later, they say. But they caution that the experience is different for everyone.
"People are more likely to make positive changes in their lives not only when their friends do, but when their friends of friends do, and when their friends of friends of friends do," said Nicholas Christakis, a professor of medical sociology at Harvard University. "People are better able to make changes in their lives - lose weight, quit smoking, become happy - when they do this with a large number of other people, and so taking advantage of your social network ties can result in a magnification of your own efforts."
Jhonny Augustin understands that well. His resolution for 2008 was to shed 30 pounds from his 237-pound frame. But the change didn't come easily. He said,"I'm a huge procrastinator, I kept putting it off until tomorrow. I didn't get to do it until the summer." However , Augustin got inspired when he saw his older brother working out. Today, Augustin weighs 190 pounds.
“Of course, change can happen only if people don't set their expectations too high or try to tackle too many changes at once; one of the biggest mistakes we make is setting unrealistic goals, ”said Dalia Llera, a psychologist and associate professor of counseling and psychology at Lesley University. "You can't accomplish in a few weeks what you haven't accomplished in a few years," said Llera.

Do you know what really troubles me? For some reason, words with silent letters have always bothered me. For example, consider these words: know, design, island, school, wrist, naughty, and salmon. All of these words have at least one letter that is not typically pronounced, and these words are just a very small part of words with silent letters in them.

   Some words are even worse, consider this word: colonel. Not only are some letters not pronounced, but letters that are not even there are pronounced.

   Even foreign languages, especially French, are guilty of this needless complexity and confusion. I know there must be some main historical reasons why the words are spelled and pronounced the way they are, but that does not mean bad traditions must continue to survive. Especially if they are no longer logical.

   Unfortunately, there is very little that anyone can do for it, because there’s no group of people who can change or have the right to change the English language for everyone. However, the only thing we can do is make changes in the way we talk and write in hopes that it catches on. For example, I pronounce the letter “l” in salmon on purpose to make people annoyed and to sound more different or complicated. I even pronounce colonel the correct or French way.

   I can only hope these two minor changes to the English language make sense to you, and you will help to keep up these minor changes forever in your everyday life.

We can learn from the passage ________.

   A. colonel is pronounced   

B. salmon is pronounced

   C. all the words with silent letters come from French

   D. linguists will solve the problem of dumb letters

Which of the following is the main reason for silent letters?

   A. French language.   B. Historical reasons.  C. Some linguists  D. Bad traditions.

The underlined phrase “catches on” probably means “________”.

   A. becomes popular   B. gets across   C. follows the fashion  D. doesn’t fall behind

Which of the following is the best title for this passage?

   A. Troubles in everyday life            B. Traps in English words

   C. Words with silent letters            D. Necessary changes of languages

Having one of those days or weeks—when everything seems to trouble you? Even if you do nothing about it, your bad mood will probably go away after some time. But with a little effort, you can forget it much faster—often within a day or two.
Walk it off
Exercise is the most popular bad-mood buster（破坏者）. A person who's in a bad mood has low energy and high tension. Taking a fast ten-minute walk, or doing some quick exercises can do wonders towards changing that bad mood.
Tune it out
Listening to your favorite music for a while can also make tension go away quickly, because music starts associations with past positive experiences we've had.
Give yourself a pep talk
Stop and listen to what's on your mind. Bad moods are often started by too many negative thoughts. Write them all down on paper; the pessimistic (悲观的) messages you've been giving yourself and then give optimistic answers. (“I still don't have a job. “vs” I have two interviews next week. ”)
Reduce your stress
Relaxation techniques are wonderful mood-lifters. These include deep breathing, stretching and visualizing (想象), all of which sound complicated but aren't. One easy way to visualize: close your eyes and picture a favorite place, such as the beach. Another simple way to clear up worries is to make a to-do list. One reason for being in a bad mood is feeling you have no options (选择权). By taking control over certain areas, you realize you're not helpless. You can make changes in your mood and life.
Avoid things that won't improve your mood
TV may not help much: You need to increase your energy level and stimulate something in your mind—that the TV show “Neighbors” won't do. And before you reach for that piece of cake and coffee, think about how mood and food are linked. Sugar and caffeine contribute to depressed moods. The better choice? Research shows that carbohydrates, such as potatoes and pasta, produce a calming effect in people who have a desire for them.
72.  We learn from the passage that it might help rid us of a bad mood_______.
A. to do nothing about it

A. It is not complicated to do so.
B. It is an area to be easily controlled.
C. It helps beat a bad mood.
D. It brings us a new technique.

B. it keeps you stay unmoved
C. it reminds you of eating and drinking
