Some scientists say that animals in the oceans are increasingly threatened by noise pollution caused by human beings.
The noise that affects sea creatures comes from a number of human activities. It is caused mainly by industrial underwater explosions, ocean drilling, and ship engines. Such noises are added to natural sounds. These sounds include the breaking of ice fields, underwater earthquakes, and sounds made by animals themselves.
Decibels (分贝) measured in water are different from those measured on land. A noise of one hundred and twenty decibels on land causes pain to human ears. In water, a decibel level of one hundred and ninety-five would have the same effect.
Some scientists have suggested setting a noise limit of one hundred and twenty decibels in the oceans. They have observed that noises at that level can frighten and confuse whales(鲸鱼).
A team of American and Canadian scientists discovered that louder noises can seriously injure some animals.
The research team found that powerful underwater explosions were causing whales in the area to lose their hearing. This seriously affected the whales' ability to exchange information and find their way. Some of the whales even died. The explosions had caused their ears to bleed and become infected(被感染的).
Many researchers whose work depends on ocean sounds are against a limit of one hundred and twenty decibels. They say such a limit would mean an end to important industrial and scientific research.
Scientists do not know how much and what kinds of noises are harmful to ocean animals. However, many scientists don’t think that noise is a greater danger than they believed. They want to prevent noises from harming creatures in the ocean.

NEW YORK— Picking a Christmas tree takes most people a few minutes, or a couple of hours if they head for the woods. Dave Murbach needs 11 months.
Almost every day of every year, Murbach’s thoughts turn to vision of a perfectly shaped evergreen tree that will take everyone's breath away.
Murbach is the man responsible for finding the towering tree that makes more attractive Manhattan’s Rockefeller Center each Christmas season.
“I'm always looking for a tree,” the center's chief gardener says. “I look for it even when I go to the beach in the summer. It' s like a homework assignment hanging over your head.”
And if he gets it wrong, there's nothing hiding it.
“Every day it's up, 400,000 people go by, and 2.5 million people watch the lighting celebration on television,”he says.
This year’s tree, a 74-foot Nomy spruce (云杉) from Richfield, Ohio, flown to New York on the world's largest cargo plane, was lighted on December 2.
The arrival of the tree leads in the Christmas season in New York — a tradition dating back to 1931, when the workers building Rockefeller Center put up a small tree with ornaments (装饰品).
The search for the next year's tree starts soon after the old tree is chopped up for wood chips and horse-jumping logs.
Murbach has three standards: The tree must be at least 65 feet high, at least 35 feet across and leaves dense (密集的) enough not to see through.
That's not as simple as it sounds. Though forests are full of evergreens, few get enough sunlight or space to fill out. And branches in snow regions often break under the weight, making trees unbalanced.
Back at the office, he sorts through hundreds of letters from people offering their trees, many addressed simply to “Mr. Christmas Tree Man.”
Though there was occasional anxiety attack and sleepless night, Murbach knows the effect the tree has on people: “It's for bringing people together, attempting to bring together people you love. That's what I hope it sets off.” But Murbach says he's always too worn out to celebrate Christmas.
1. Which is the correct order of the events in the passage?
a. Murbach’s thoughts turn to a perfectly shaped tree.
b. 2.5 million people watch the Christmas tree.
c. The tree is flown to New York.
d. It was lighted on December 2.
e. The tree is chopped up.
f. Murbach searches for the tree.
A. a, b, c, d, e, f B. c, d, b, f, e, a
C. c, d, e, b, a, f D. a, f, c, d, b, e
2. Murbach spends a lot of time that are exhibited in Manhattan’s Rockefeller Center each Christmas season.
A. taking care of Christmas trees
B. deciding on the perfect evergreens
C. sorting the letters from people
D. deciding the TV programs
3. Why does Murbach take his job seriously?
A. Because he wants everyone to be happy with his choice.
B. Because he hopes to make everybody unable to breathe.
C. Because he enjoys showing off.
D. Because he wishes to attract people's attention to himself.
4. According to Murbach' s standard of trees, the best tree must_______ .
A. be evergreen
B. have lots of space between their branches
C. be tall enough not to see through
D. be equally balanced
5. What kind of person do you think Murbach is?
A. A person always ignoring his family.
B. A person full of love.
C. A person devoted to his work.
D. A person with great anxiety.

A recent survey shows 6. 78% of all the 17,000 people questioned have developed environmentally friendly habits in their daily lives.They are doing things, such as taking reusable shopping bags to the store and setting the air conditioner at a temperature above 26oC in summer.
On many popular 7. (society) networking websites, people are advocating a low-carbon lifestyle.Their tips include using the stairs and public transport more frequently 8. elevators and cars.They hope this lifestyle 9. (become) more than just a trend within certain groups.
