    Since the beginning of history, man has been fascinated by the idea of living forever, of winning the fight against death and disease. So far, this has only remained a dream, though a very powerful one. Many people have wondered whether it would be possible to find a way to preserve human bodies, and what would be the best way to preserve human bodies.

    It has long been known that meat or fruit can be kept fresh for long periods by freezing; in ancient China, for example, food was stored with ice to keep it fresh. This method could also be useful for preserving humans, and in fact many people have explored this possibility.

    However, most living beings that exist under warm conditions die when frozen. This is because of the harmful effects of freezing ice crystals, which are not only larger than the volume of the water originally in the cells, but also form sharp cutting shapes that harm the cells.

    In the 1940s Dr B. J. Luyet and a group of scientists in England were working on the problem of freezing cells without damaging them. Since the harm caused by ice crystals was the main cause of the damage, Luyet suggested removing some or all of the water from the cells before freezing them.

    Using living cells from chicken, Luyet and his assistants discovered that they could partly dry the chicken cells, using a mixture of the white part of an egg and glycerin, a clear thick liquid made chiefly from fats and oils. Some success was obtained. The chicken cells were dried, frozen for a period of time, and then carefully unfrozen.

    Almost all the cells recovered when they reached normal temperature. Since then, the cooling of whole animals to a temperature very much below freezing point for later unfreezing has become more of a possibility, and the glycerin method would probably be used to accomplish this. When this can be done completely and successfully, science will have moved much closer to its aim of freezing and storing incurable patients until the day they can be cured.

(1)、It seems that the idea of preserving human bodies          .
A、is impractical B、comes from that of storing meat and fruit fresh by freezing C、is quite funny D、doesn't make any sense
(2)、From the fact that most living things existing under warm conditions die when frozen, the scientists realize that            .
A、living things cannot be frozen actually B、it is impossible for them to freeze human beings C、the water from the living cells should be removed D、cells cannot recover when they are carefully unfrozen
(3)、Glycerin can be used         .
A、to remove water from living cells B、to unfreeze living cells C、to freeze living cells D、to change the shape of crystals
(4)、What is the passage mainly about?
A、The harmful effects of freezing food B、How to preserve food C、How to remove water from living cells D、The exploration of preserving human bodies
(5)、What is the most probable meaning of the underlined word "fascinated"?
A、attracted B、freed C、afraid D、sad

How green are you? Do you care about protecting the environment and saving energy? We all need a healthy environment, but we produce waste every day and it does harm to our environment. Though we are young, we can still do something to help. In fact, even the simplest everyday activities can make a real difference to the environment. Here are some ideas for you. Remember these three words: Reduce, reuse and recycle.
REDUCE
Reduce means “use less.” Don't waste things. This saves money and reduces pollution and waste going into the environment. Before we buy something new, think whether it is really necessary— or maybe the old one will be just as good! When we do buy things, choose local produces if possible, and try not to buy too many things form abroad. It may cost a lot of money to bring them to us.
REUSE
Reuse means “use again.” Use things for as long as possible. When we buy things, make sure that they last a long time. We should look after them so that they will last, and we should repair them if we can instead of throwing them away and buying new ones. Don't use a paper cup or a paper bag. It's better to use a china cup and a lunch box because you can use them again.
RECYCLE
Recycle means “change things into something else.” Although it takes energy to change something into something else, it's better than throwing things away or burning them. Find out what can be recycled in your neighbourhood and take part in recycling programmes. We should also buy products made from recycled materials, such as recycled paper, to help save trees.

When Leon Martin asked for his parents' advice on how to become a UX designer(设计师), they both went silent. "In fact, I had no idea what he was talking about, " said Anne, his mother. "I don't know whether he was talking about designing clothes, computer programmes of a fancy brand of bike. "

Even when her 18-year-old son explained that it was something about"behind the scenes" online design, his mother was still a bit lost. "I felt like I had totally failed as a parent, " she said. "My job as a parent is to open doors so my children can achieve their potential(潜力), but now can I do that when I don't even understand what their dreams are?"

Anne is not alone. Recent research has found that more than 2/3 of parents in England are now facing the problem. When their children express interest in new education and job choices, they may know nothing about them. More than 75% of parents feel it is almost impossible to offer their children good advice in such a fast-changing job market. 

Michelle Reed did a survey of over 2, 000 parents of secondary school students in England. She found that many parents were afraid their children hardly follow them. "We all know that parents' opinions and suggestions play an important role in shaping and influencing their children's career dreams, " she said. "But we usually depend much on our own experiences. And things have changed so much since most of us were at school. "

Bryony Mathew, the writer of Qubits and Quiver TreesAwesome Careers of the Future, said the world was changing so rapidly that parents should not try to decide on certain careers for their children.
