　　When We Are Asleep

2017年職稱英語試題理工類復(fù)習(xí)模擬題「含答案」

　　Everyone dreams，but some people never recall their dreams，or do so very rarely. Other people always wake up with vivid recollections (記憶) of their dreams，though they forget them very quickly. In an average night of eight hours' sleep，an average adult will dream for around one hundred minutes，probably having three to five dreams，each lasting from ten to thirty minutes.　　Scientists can detect when someone is having a dream by using an instrument which measures the electrical waves in the brain. During dreaming, these waves move more quickly. Breathing and pulse rate also increase，and there are rapid eye movements under the lids, just as though the dreamer were really looking at moving objects. These signs of dreaming have been detected in all mammals (哺乳動物) studied, including dogs, monkeys, cats, and elephants, and also some birds and reptiles (爬行動物). This period of sleep is called the "D" state for around 50% of their sleep;the period reduces to around 25% by the age of 10.

　　Dreams take the form of stories，but they may be strange and with incidents not connected，which make little sense. Dreams are seldom without people in them and they are usually about people we know. One estimate says that two-thirds of the "cast" of our dream dramas are friends and relations. Vision seems an essential part of dreams，except for people blind from birth. Sound and touch are senses also often aroused，but smell and taste are not frequently involved. In "normal" dreams，the dreamer may be taking part，or be only an observer. But he or she cannot control what happens in the dream.

　　However, the dreamer does have control over one type of dream. This type of dream is called a "lucid"(清醒的) dream. Not everyone is a lucid dreamer. Some people are occasional lucid dreamers. Others can dream lucidly more or less all the time. In a lucid dream，the dreamer knows that he is dreaming.

　　It's in the Cards

　　In recent years, more and more people have been paying for things with credit cards. There are now 565 million credit cards worldwide, but it doesn't stop there. Debit cards (電子記賬卡) are being issued by banks, and store cards are being offered by many department stores. Bills and coins are gradually being replaced by "plastic money." In many countries, phone cards have been introduced for people to use in pay phones. In addition, cards made of paper are being replaced by plastic ones by many organizations and clubs. For example, if you belong to a sports club, your membership card may well be made of plastic.

　　How safe is the plastic used to make these cards, though? Until now, most cards have been made from a plastic called PVC. While PVC is being produced, harmful chemicals are released into the atmosphere. One of the most dangerous chemicals that is released is dioxin, which is known to cause cancer in humans. A further problem is that, when a PVC card is thrown away, it is not biodegradable; this means that it does not "break down" and cannot be recycled. Obviously, recycling reduces pollution of the environment.

　　The executive director of the environmental organization and charity Greenpeace, Peter Melchett, says, "If there is a solution to this - and an alternative then it would be madness not to use it." Greenpeace has found a solution and an alternative. Their new credit card is made entirely from a biodegradable plastic that uses plants. The card breaks down in around three months in soil; in this way, it is recycled. In contrast, a PVC card lasts for centuries Greenpeace hopes that many organizations will soon follow their example and issue cards that do not threaten the public health.
