To accurately say that your family and friends don't care about you would be a very rare situation.Maybe you're being too negative and overlooking the gestures of love they show you.They don't even have to be big gestures,but it's the little things they did for you that count.2.Start showing people you care,so they can show you back in kind.

●I really dislike this person.

If you dislike a person,focusing on his had qualities is not going to make things better.You need to know that he is human too,which means he makes mistakes.3.Focus on his good qualities,and repeat them to yourself.

Being an astronaut sounds cool, doesn't it？In space, they get to do some pretty amazing things, like floating in zero gravity.

However，there are also plenty of things that astronauts can't do because of their weightless environment, and that's very sad. What's worse, they can't even let their sadness show—because it's impossible to cry in zero gravity.

Of course, astronauts can still produce tears. But crying is much more difficult in space，reported The Atlantic in January. Without gravity, tears don't flow downward out of the eyes like they do here on Earth. This means that when you cry in space, your tears have nowhere to go—they just stick to your eyes.

In May 2011, astronaut Andrew Feustel experienced this during one of his spacewalks.“Tears，” he said, “don't fall off your eye... They just kind of stay there.”

Besides making your vision unclear, this can also cause physical pain. Back on Earth, tears are supposed to bring comfort to the eyes.But that's not the case in space.The space environment dries out astronauts' eyes, and when tears suddenly wet the eyes, it can cause pain rather than comfort. “My right eye is painful like crazy.” Feustel told his teammate during the walk.

Since gravity doesn't work in space, astronauts need some extra help to get rid of the tears.Feustel chose to rub his eyes against his helmet to wipe the tears away. Another choice is to just wait—“When the tears get big enough they simply break free of the eye and float around，”astronaut Ron Parise told The Atlantic.

There are lots of small things—things like crying—that we are so used to on Earth. We usually take them for granted, until they become a problem in a totally different environment，like space. There, astronauts can't talk to each other directly. They also can't eat or drink in normal ways. They can't even burp(打隔), because there is no gravity to hold the food down in their stomach. If they do burp, they just end up throwing up(呕吐) everything in their stomach，according to the UK National Space Center.

Thus, perhaps it's only space explorers who can honestly say：“Gravity, you're the best.”

1.What can we conclude from Paragraphs 2 and 3?

A．Astronauts are unable to feel sad in space.

B．Astronauts produce fewer tears in space.

C．Tears produced in space flow down more slowly.

D．Tears produced in space don't flow downward.

2.What effect do tears have on astronauts?

A．They cause physical pain.

B．They bring comfort to them.

C．They make their vision clearer.

D．They float around and cause trouble.

3.What can the astronaut do to get rid of the tears?

A．Rub his eyes against his helmet to let the tears float forward.

B．Rub his eyes by hand to let the tears float around.

C．Get the tears big enough to fall off of his eyes.

D．Get the tears big enough to break away from his eyes.

4.What's the last but one paragraph mainly about?

A．Suggestions on how astronauts can stay comfortable in space.

B．Other basic things that are difficult to do in space.

C．Why burping is impossible in space.

D．Things that humans can't do without gravity.

Food production does great harm to our environment.There are many procedures involved in the manufacture of food that result in greenhouse gases and other pollutants.Some procedures require the consumption of large amounts of fossil fuels,such as the transportation and storage of food products.Other factors that cause great damage to our environment include the overuse of fresh water.

The production of beef is more damaging to the environment than that of any other food we consume,Raising large numbers of cattle requires the production of large amounts of food for the animals.It’s estimated that producing one pound of beef requires seven pounds of feed.

Land use is also a problem.If the cattle are free-range cattle,large areas of land are required for them to live on.This has led to disastrous forest cutting and the loss of rare plants and animal species,particularly in tropical rain forests in Central and South America.

Another problem specific to beef production is methane emissions (甲烷排放).Although many people are aware of the damaging effects of carbon dioxide,they don’t realize methane’s global warming potential is 25 times worse,making it a more dire problem.

Unfortunately,beef consumption is growing rapidly.This is the result of simple supply and demand factors.Specifically,there are two main causes of demand that are encouraging the production of more supply.First,the increase in the world population means there are more people to consume meat.The second factor is socioeconomic advancement.As citizens in developing nations become financially stable,they can afford to buy more meat.

Therefore,one way to reduce the greenhouse gas emissions is for people around the world to significantly cut down on the amount of beef they eat.

1.Which of the following is TRUE?

A. Raising free-range cattle is eco-friendly.

B. People cut down trees for animal habitats.

C. Producing beef can damage the environment.

D. Carbon dioxide causes far more harm than methane.

2.The underlined word “dire” in Para.4 means　　　　 .

A. urgent　　 B. common

C. typical　　 D. avoidable

3.Beef production is growing rapidly because　　　　 .

A. more people are in demand of beef

B. developing countries raise more cattle

C. more land is available to raise cattle

D. the cost of raising cattle is relatively low

4.The author writes this article to　　　　 .

A. describe the booming of the beef production

B. emphasize the advantages of beef production

C. condemn the deforestation of the rain forest

D. argue for a decrease in beef consumption

Space is where our future is — trips to the Moon, Mars and beyond. Most people would think that aside from comets (彗星) and stars, there is little else out there. But, since our space journey started we have left so much trash there that scientists are now concerned that if we don't clean it up, we may all be in mortal（致命的）danger.

The first piece of space junk was created in 1964, when the American satellite Vanguard I stopped operating and lost its connection with the ground center. However, since it kept orbiting around the Earth without any consequences, scientists became increasingly comfortable abandoning things that no longer served any useful purpose in space.

It is estimated that there are now over 500,000 pieces of man-made trash orbiting the Earth at speeds of up to 17,500 miles per hour. The junk varies from tiny pieces of paint chipped off rockets to cameras, huge fuel tanks, and even odd items like the million-dollar tool kit that astronaut Heidemarie Stefanyshyn Piper lost during a spacewalk.

The major problem with the space trash is that it may hit working satellites and damage traveling spacecraft. Moreover, pieces of junk may collide with each other and break into pieces which fall back to the Earth. To avoid this, scientists have invented several ways for clearing the sky. Ground stations have been built to monitor larger pieces of space trash to prevent them from crashing into working satellites or space shuttles. Future plans include a cooperative effort among many nations to stop littering in space and to clean up the trash already there.

1.What was the first piece of man-made space trash ?

A. A camera.　　 B. A tool kit.

C. A fuel tank.　　 D. A broken satellite.

2.Why were scientists NOT concerned about space trash in the beginning ?

A. It no longer served any useful purpose.

B. It was millions of miles away from the Earth.

C. It did not cause any problems.

D. It was regarded as similar to comets and stars.

3.Which of the following statements is true about space junk ?

A. It is huge, heavy machines.

B. It never changes position.

C. It floats slowly around the Earth.

D. It may cause problems for space shuttles.

4.What has been done about the space trash problem ?

A. Scientists have cleaned up most of the trash.

B. Large pieces of space trash are being closely watched.

C. Many nations have worked together to stop polluting space.

D. Ground stations are built to help store the trash properly in space.
