Scientists announced that they had found the gravitational waves(引力波)that confirmed a prediction made by Albert Einstein a century ago.The discovery,made with the Laser Interferometer Gravitational—Wave Observatory, known as LIGO,is the milestone(里程碑)in a decades—long search for signs of this phenomenon."The discovery will open a new window onto the universe,"said David Reitze,executive director of LIGO.

Since humans first watched skyward,we have relied on light of all wavelengths to describe the universe.The light that could be seen first showed the starry heavens,while infrared(红外线的)waves allowed us to see older and more distant stars.

But now,researchers will be able to sense the universe in a whole new way: with their "ears"."We can hear gravitational waves.We can hear the universe,"Gabriela Gonzalez,LIGO's spokeswoman at Louisiana State University,said."That's one of the beautiful things about this: We are not only going to be seeing the universe,we are going to be listening to it."

Gravitational waves,which Einstein predicted as part of his general theory of relativity,occur as objects accelerate or decelerate through space,much the way a boat moving on a lake sends waves across the water's surface. But they're so tiny that until now it's been nearly impossible to find them,even those caused by something as large as a planet moving around the sun.

To pick up this signal,scientists have to look for violent events in the universe.This particular signal appears to have been caused by a collision.That occurred about 1.3 billion years ago between two black holes,holding 29 and 36 solar masses(太阳质量).

Fiona Harrison,chair of Caltesh's division of physics,mathematics and astronomy,guessed that hundreds of new events would be found over the next few years,allowing scientists to perform a range of different types of studies. "There are probably many events we haven't dreamed of and this is just the beginning,"she said.

1.Why did Gabriela Gonzalez think LIGO's discovery important?

A. It confirmed Einstein's scientific prediction.

B. It allowed scientists to see more distant stars.

C. It changed traditional ideas about the universe.

D. It offered different way to study the universe.

2.It's hard to find gravitational waves because they .

A. are too far to be felt

B. are too weak to be observed

C. are disturbed bu other planets

D. disappear soon after they happen

3.Which of the following would scientists consider to be a violent event?

A. Hearing the universe.

B. Searching for infrared waves.

C. A collision between black waves.

D. A planet moving around the sun.

4.It can be concluded that .

A. gravitational waves also exist in objects at rest

B. there's a long way to go in studying the universe.

C. gravitational waves show the beginning of the universe.

D. scientists began studying gravitational waves in recent years.

Lots of people find it hard to get up in the morning and put the blame on the alarm clock. In fact, the key to easy morning wake-up lies in resting your body clock 1. Here is how to make one.

2. In order to make a change, you need to decide why it’s important. Do you want to get up in time to have breakfast with your family, get in some exercise or just be better prepared for your day?

• Keep your sleep/wake schedule on weekends. If you’re tired out by Friday night, sleeping in on Saturday could sound wonderful. But compensating (弥补) on the weekends actually feeds into your sleepiness the following week, a recent study found.4.

• Keep a record and evaluate it weekly. Keep track of your efforts and write down how you feel. After you’ve tried a new method for a week, take a look at your record.5. If rot, take another look at other methods you could try.

“My kids really understand solar and earth-heat energy,” says a second-grade teacher in Saugus, California. “Some of them are building solar collectors for their energy course.” These young scientists are part of City Building Educational Program (CBEP), a particular program for kindergarten through twelfth grade that uses the stages of city planning to teach basic reading, writing and math skills and more.

The children don’t just plan any city. They map and analyze (分析) the housing, energy, and transportation requirements of their own district and foretell its needs in 100 years. With the aid of an architect (建筑师) who visits the classroom once a week, they invent new ways to meet these needs and build models of their creations. “Designing buildings of the future gives children a lot of freedom,’’ says the teacher who developed this program. “They are able to use their own rich imagination and inventions without fear of blame, because there are no wrong answers in a future context. In fact, as the class enters the final model-building stage of the program, an elected ‘official’ and ‘planning group’ make all the design decisions for the model city and the teacher steps back and becomes an adviser.

CBEP is a set of activities, games and imitations that teach the basic steps necessary for problem-solving: observing, analyzing, working out possible answers, and judging them based on the children’s own standards.

1.The program is designed to_________.

A. direct kids to build solar collectors

B. train young scientists for city planning

C. develop children’s problem-solving abilities

D. help young architects know more about designing.

2.An architect pays a weekly visit to the classroom to ________.

A. find out kids’ creative ideas B. help kids with their program

C. discuss with the teacher D. give children a lecture

3.Who is the designer of the program?

A. An official. B. An architect. C. A teacher. D. A scientist

4.The children feel free in the program because __________.

A. they can design future buildings themselves

B. they have new ideas and rich imagination

C. they are given enough time to design models

D. they need not worry about making mistakes
