Continue to Protect or Destroy Ecosystem
Biosphere Ⅱ was a spectacular failure. The gleaming glass-and-concrete habitat sprawling across the desert in Oracle, Arizona, was supposed to support eight human "biospherians" for two years. But the seal has to be broken before the experiment ended in 1993. Oxygen had fallen to levels normally seen at an elevation of 1 7,500 feet. Nitrous oxide had risen to the point where it threatened to cause brain damage. The fresh water supply became contaminated, and vines smothered ( 厚厚地覆盖 ) food plants. Insect pollinators (传授花粉的生物) and many other species became extinct. By the end, Biosphere Ⅱ was overrun with swarms of ants and cockroaches.
Scientists who gathered recently to review the Biosphere Ⅱ experiment reached a disturbing conclusion: "No one yet knows how to engineer systems that provide humans with the life-supporting services that natural ecosystems produce for free."
The problem is that these ecosystems are undergoing wrenching changes. Water and air quality, while improving in some regions, are deteriorating in many others. Carbon dioxide levels in the atmosphere arc climbing. The world's population could reach 10 billion by 2050. And famed Harvard biologist Edward O. Wilson says the current rate of species losses puts us "in the midst of one of the great extinction spasms ( 突然进发 ) of geological history." All of which makes many ecologists wonder whether humans too will soon become extinct. It's an incredibly important but incredibly difficult question. If we continue on this course, we're heading for a world in which we will have to engineer services we've always received for free from nature. That's why the failure of Biosphere Ⅱ was so disturbing: it proves that we don't yet know how to do that.
The Biosphere Ⅱ experience demonstrated that maintaining human life is a tricky proposition-especially if we can no longer rely on the services provided by natural ecosystems. If we are currently living through a mass extinction, as Wilson believes, we should consider the past. In the great Permian extinction 245 million years ago, 96 percent of species perished. Eventually, the Earth was repopulated with a rich collection of new species, but it took 100 million years. "That should give pause to anyone who believes that what Homo sapiens ( 现代人 ) destroys, nature will redeem," Wilson says. "Maybe so, but not within any length of time that has meaning for contemporary humanity."

The seal of the Biosphere Ⅱ had to be broken before the experiment ended because__________
A．the bad climate of the desert made the human biospherians ill
B．the poisonous air caused brain damage of the human biospherians
C．the ecosystems in it became so bad that the human biospherians can't live
D．the human biospherians were defeated by swarms of ants and cockroaches

回答题：
The First Four Minutes
When do people decide whether or not they want to become friends? During their first four minutes together, according to a book by Dr. Leonard Zunin. In his book, Contact: The first four minutes, he offers this advice to anyone interested in starting new friendships:46. A lot of people's whole lives would change ifthey didjustthat.
You may have noticed that average person does not give his undivided attention to someone he has just met.47. If anyone has ever done this to you, you probably did not like him very much.
When we are introduced to new people, the author suggests, we should try to appear friendly and self- confident. In general, he says, " People like people who like themselves."
On the other hand, we should not make the other person think we are too sure of ourselves. It is important to appear interested and sympathetic, realizing that the other person has his own needs, fears, and hopes. Hearing such advice, one might say, "But I'm not a friendly, self-confident person. That's not my nature. It would be dishonest for me to act that way."
48. We can become accustomed to any changes we choose to make in our personality. "I is like
getting used to a new car. It may be unfamiliar at first, but it goes much better than the old one."
But isn't it dishonest to give the appearance of friendly self-confidence when we don't actually feel that way? Perhaps, but according to Dr. Zunin, "total honest" is not always good for social relationships, especially during the first few minutes of contact. There is a time for everything, and a certain amount of play-acting may be best for the first few minutes of contact with a stranger. That is not the time to complain about one's health or to mention faults one finds in other people. It is not the time to tell the whole truth about one's opinions and impressions.
49. For a husband and wife or a parent and child, problems often arise during their first four minutes together after they have been apart. Dr. Zunin suggests that these first few minutes together be treated with care. If there are unpleasant matters to be discussed, they should be dealt with later.
The author says that interpersonal relations should be taught as a required course in every school, along with reading, writing, and mathematics.50that is at least as important as how much we know.
A．In reolv, Dr. Zunin would claim that a little practice can help us feel comfortable about changing our social habits
B．Much of what has been said about strangers also applies to relationships with family members and friends
C．In his opinion, success in life depends mainly on how we get along with other people.
D．Every time you meet someone in a social situation, give him your undivided attention for four minutes
E．He keeps looking over the other person's shoulder, as if hoping to find someone more interesting in another part of the room
F．He is eager to make friends with everyone
