Einstein. It(51)to the category of the theory of relativity, and it equates energy with mass.

All things are made up of atoms. When(52)of an atom travels at almost the speed of light(53)we put more energy into it to increase the speed, it begins to in crease in mass. The energy that makes it travel fast cannot make it travel(54)the speed of light—nothing(55)light can travel that fast- so the energy goes into the thing(56)and increases its mass. Energy(57)into mass.

Why is the theory called the theory of relativity？ A thing that is relative depends upon(58)else to identify it or to define it. In relativity theory we identify or define mass, time, and length(59)to the speed of light.

When something is at rest, it looks(60)in length. However, when it travels at almost the speed of light, it becomes(61). Time also changes. However, the change in time is(62)to the change in length. The length of a thing becomes short(63)time becomes long.

Taking a Nap during the Day

Medical experts say most Americans do not get enough sleep. They say more Americans need to 【51】______ for a short period in the middle of the day. They are advising people to sleep lightly 【52】______ continuing with other activities. One study earlier this year found that persons who sleep for a few minutes during the day were less likely to die of 【53】______ disease. The study followed more than 2,300 Greek adults 【54】______ about six years. Adults who rested for half an hour at least three times a week had a 37 percent lower 【55】______ of dying from heart disease than those who did not nap.

Study organizers said the strongest 【56】______ was in working men. They said naps might improve health by mitigating(减低) tension 【57】______ by work.

Some European and Latin American businesses have supported the idea of 【58】______ for many years. They urge(催促) people to 【59】______ work, go home and have a nap before returning. In the United States, some companies let workers rest briefly in their offices. They believe this reduces mistakes and accidents, and also 【60】______ the amount of work a person can do.

Sleep experts say it is likely that people 【61】______ more mistakes at work than at other times. They say people should not carry out important duties 【62】______ they feel sleepy. And they say the best thing to do is to take a nap. About twenty minutes of rest is all you 【63】______. Experts say this provides extra energy and can increase your 【64】______ until the end of the day. But experts 【65】______ that a nap should last no more than twenty to thirty minutes. A longer nap will put the body into deep sleep and waking up will be difficult.

Dark Forces Dominate Universe

The earth, moon, sun and all visible stars in the sky make up less than one percent of the universe. Almost all the rest is dark matter and dark energy, unknown forces that(51)astronomers.

Observations in recent years have changed the basic(52)of how the universe evolved and have indicated how little is known about the major forces and substances that(53)our world.

Astronomers now know that luminous (发光的) matter -- stars, planets and hot gas -- accounts(54)only about 0.4 percent of the universe. Non-luminous components, such as black holes and intergalactic (星系间的) gas,(55)up 3.6 percent. The rest is either dark matter, about 23 percent, or dark energy, about 73 percent.

Dark matter, sometimes(56)"cold dark matter," has been known for some time. Only recently have researchers come to understand the key role it(57)in the formation of stars, planets and even people.

"We(58)our very existence to dark matter," said physicist Paul Steinhardt and a co-author of a review on dark matter which(59)not long ago in the journal Science.

"Dark matter dominated the structure(68)in the early universe," Steinhardt said. "For the first few billion years dark matter contained most of the mass of the universe. You can think of ordinary matter(61)a froth (泡沫) of an ocean of dark matter. The dark matter clumps (结成块) and the ordinary matter falls into it. That(62)to the formation of the stars and galaxies (星系)."

Without dark matter, "there would be virtually no structures in the universe."

The nature of dark matter is(63). It cannot be seen or detected directly. Astronomers know it is there because of its(64)on celestial (天体的) objects that can be seen and measured.

But the most dominating force of all in the universe is called dark energy, a recently(65)power that astronomers say is causing the galaxies in the universe to separate at a faster and faster speed.
