New genetic analysis has revealed that many Amazon tree species are likely to survive human-made climate warming in the coming century, contrary to previous findings that temperature increases would cause them to die out. A study, 1 in the latest edition of Ecology and Evolution, reveals the 2 age of some Amazonian tree species -- more than 8 million years -- and 3 shows that they have survived previous periods as warm as many of the global warming imagined periods 4 for the year 2100.
The authors write that, having survived warm periods in the past, the trees will 5 survive future warming, provided there are no other major environmental changes. 6 extreme droughts and forest fires will impact Amazonia as temperatures 7 , the trees will stand the direct impact of higher temperatures. The authors 8 that as well as reducing greenhouse gas emissions to minimize the risk of drought and fire, conservation policy should remain 9 on preventing deforestation（采伐森林）for agriculture and mining.
The study disagrees with other recent researches which predicted tree species’ extinctions 10 relatively small increases in global average air temperatures.
Study co-author Dr Simon Lewis (UCL Geography) said the 11 were good news for Amazon tree species, but warned that drought and over-exploitation of the forest remained major 12 to the Amazon’s future.
Dr Lewis said: “The past cannot be compared directly with the future. while tree species seem likely to 13 higher air temperatures than today, the Amazon forest is being transformed for agriculture and 14 , and what remains is being degraded by logging, and increasingly split up by fields and roads.
“Species will not move as freely in today’s Amazon as they did in previous warm periods, when there was no human 15 . Similarly, today’s climate change is extremely fast, making comparisons with slower changes in the past 16 .”
“With a clearer 17 of the relative risks to the Amazon forest, we 18 that direct human impacts -- such as forest clearances for agriculture or mining -- should remain a key point of conservation policy. We also need more aggressive 19 to reduce greenhouse gas emissions in order to make minimum the risk of drought and fire impacts and 20 the future of most Amazon tree species.”

Personal computers and the Internet give people new choices about how to spend their time.
Some may use this freedom to share less time with certain friends or family members, but new technology will also let them stay in closer touch with those they care most about. I know this from personal experience.
E-mail makes it easy to work at home, which is where I now spend most weekends and evenings. My working hours aren’t necessarily much shorter than they once were but I spend fewer of them at the office. This lets me share more time with my young daughter than I might have if she’d been born before electronic mail became such a practical tool.
The Internet also makes it easy to share thoughts with a group of friends. Say you do something fun, see a great movie perhaps-and there are four or five friends who might want to hear about it. If you call each one, you may tire of telling the story.
With E-mail, you just write one note about your experience, at your convenience, and address (="tell)" it to all the friends you think might be interested. They can read your message when they have time, and read only as much as they want to. They can reply at their convenience, and you can read what they have to say at your convenience.
E-mail is also an inexpensive way stay in close touch with people who live far away. More than a few parents use E-mail to keep in touch, even daily touch, with their children off at college.
We just have to keep in mind that computers and the Internet offer another way of staying in touch. They don’t take the place of any of the old ways.
We can infer that passage is to ________.
A．explain how to use the Internet B．describe the writer’s joy of keeping up with the latest technology C．tell the merits(价值) and usefulness of the Internet D．introduce the reader to basic knowledge about personal computers and the Internet
A．spend less time working B．have more free time with his child C．work at home on weekends D．work at a speed comfortable to him
A．reach a group of people at one time conveniently B．keep one’s communication as personal as possible C．pass on much more information than the latter D．get in touch with one’s friends faster than the latter
A．Computer: New Technological Advances B．Internet: New Tool to Maintain Good Friendship C．Computers Have Made Life Easier D．Internet: a Convenient Tool for Communication
