In space, they get to do some pretty amazing things, like floating in zero gravity.However, there are also plenty of things th

2、at astronauts cant do because of their weightless environment, and thats very sad. Whats worse, they cant even let their sadness show because its 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 Janu

3、ary. Without gravity, tears dont 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 gothey just stick to your eyes.In May 2020, astronaut Andrew Feustel experienced this during one of his spacewalks. Tears, he said, dont fall o

4、ff of 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 thats not the case in space. The space environment dries out astronauts eyes, and when tears suddenly wet the eyes,

5、it can cause pain rather than comfort. My right eye is painful like crazy. Feustel told his teammate during the walk.Since gravity doesnt 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

6、 to just waitWhen 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 thingsthings 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

7、 environment, like space. There, astronauts cant talk to each other directly. They also cant eat or drink in normal ways. They cant even burp (打嗝), 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, acco

11、 B. Better life with gravityC. In the sky, you cant cry D. No Gravity, no tearsBWhat will man be like in the future in 5,000 or even 50,000 years from now? We can only make guesses, of course, but we can be sure that he will be different from what he is today, for man is slowly changing all the time

12、.Let us take an obvious example. Man, even five hundred years ago, was shorter than he is today. Now, on average, men are about three inches taller. Five hundred years is relatively a short period of time, so we may suppose that man will continue to grow taller. Again, in the modern world we use our

13、 brains a great deal. Even so, we still make use of only about 20% of the brains capacity. As time goes on, however, we shall have to use our brains more and more, and finally we shall need our brains more and more, and finally we shall need larger ones! This is likely to bring a physical change too

14、: the head, in particular the forehead, will grow larger.Nowadays our eyes are in constant use. In fact, we use them so much that very often they become weaker and we have to wear glasses. But over long period of time it is likely that mans eyes will grow stronger.On the other hand, we tend to make

15、less use of our arms and legs. These, as a result, are likely to grow weaker. At the same time, however, our fingers will grow more sensitive because they are used a great deal in modern life.But what about hair? This will probably disappear from the body altogether in course of time because it does

16、 not serve a useful purpose any longer. In the future, then, both sexes are likely to be bald.Perhaps all this gives the impression that future man will not be a very attractive creature to look at! This may well be true. All the same, in spite of all these changes, future man will still have a lot

17、in common with us. He will still be a human being, with thoughts and emotions similar to our own.5The passage mainly tells us that _.A. Mans life will be different in the future B. Future man will look quite different from usC. Man is growing taller and uglier as time passes D. Mans organs functions

18、 will change6What serves as the evidence that man is changing?A. Man has got stronger eyes now than he ever had.B. Mans hair is getting thinner and thinner.C. Mans arms and legs have become lighter and weaker.D. Man has been growing taller over the past 500 years.7The change in mans size of the fore

19、head is probably because _.A. he makes use of only 20% of the brains capacityB. his brain has grown larger over the past centuriesC. he will use his brain more and more as time goes onD. the other 80% of his brain will grow in due time8Which of the following is TRUE about a human being in the future

20、?A. He is hairless because hair is no longer useful.B. He has smaller eyes and wears better glasses.C. His fingers grow weaker because he doesnt have to make use of them.D. He thinks and feels in a different way.CWestern New Bridge Library AnnouncementShortened Library Hours for Spring BreakLibrary

29、 of other popular flowers.Some people say roses are difficult to grow. But you have a good chance of success if you start with a few suggestions from experts. You should plant your roses where they can get sunshine for about six hours on bright days. You can buy roses from a garden center or by mail

30、 order. You can buy potted roses, also known as container roses, or bare-root plants. Each kind has its fans.Some gardeners say potted roses are easier to plant. They say the roots develop better. But Jeffrey Dinslage, an expert, points out that bare-root roses come without soil. So they weigh less

31、to transport.Another expert advises getting bare-root roses as close to planting time as you can. If they arrive before you are ready to plant them, make sure the packing material is moist. Keep the plants in a cool, dark place. The resting plants have no leaves but still need water. When growing ro

32、ses, the soil should feel moist deep down. Watering should be done in the morning.But do not water too much. People often ask Jeffrey Dinslage about unhealthy discoloration on rose leaves. He says the spots are usually caused by too much water. After heavy rains or too much watering, he advises pulling away mulch, the substance used to protect the roots, to improve the quality of the soil, temporarily from
