Many of our favorite travel destinations are in danger of being changed badly by increased temperatures and rising seas. The following are some of the places that may be in danger and some that are already experiencing the effects of global warming.
The Everglades, Florida: Perhaps no region of the country is as unprotected to climate change as Florida. Even a slight increase in temperature and water level could devastate popular destinations like the Everglades, Miami Beach and the Keys.
Australia’s Great Barrier Reef: One of the most impressive natural habitats in the world, the Great Barrier Reef could be killed by increased water temperatures and the resulting coral bleaching (漂白法). Australia is particularly easily damaged by global warming because of its large number of fragile (脆弱的) ecosystems, uncertain water sources and a large group of people gathering on the coast.
Dalian, China: Fast-growing China, shown here during a heat wave last year, is opening about one coal factory every day this year. Along with the U.S., China is one of the world's leading contributors to the greenhouse gases , which can lead to the increase in the Earth's temperature.
Venice, Italy: No stranger to flooding, Venice has invested $4.5 billion in a floodgate system that is due to open in 2012. But the frequent changing ocean levels have made people question the floodgates' ability to hold out the rising waters.
London, England: Designed to protect London from storms and extremely high tides, the Thames Barrier was opened in 1984. Some analysts fear that rising oceans will create conditions beyond the capabilities the barrier was designed to meet.

A. protect B. destroy C. swallow D. enlarge
2.What can endanger Great Barrier Reef directly?

Here are a few of our favorite entries so far in our “Your Life: The Reader’s Digest Version” contest. After reading these, head over to Facebook and submit (提交) your own story about a special moment or lesson that shaped your life.
“There’s Always a John”
By Darla Boyd
My first year of teaching, there was a kid named John in my class. John was difficult to control and he nearly drove me crazy. While talking about him one day, an old teacher put his hand on my shoulder and said, “There will always be a John. Your job is to lean, to discover what make him different and help him grow better.” The next year, there was indeed another John. In the last 20 years, I’ve learned to enjoy all the kids like John. That advice taught me that there is something to appreciate in everyone.
“An Early Key Lesson”
By Elaine West
Before I began my first teaching job, my mother, a teacher of 30 years, gave me a very special gift, five simple words that have had an effect on my entire life: “Make friends with the janitor (门卫).” Her wisdom taught me the respect for all types of characters and continue to enrich my life to this day. Just five little words but what an impact they can have when you take them to heart.
“Raising Mommy”
By Jan Davis
Being a mother can always present challenges and rewards. Someone told me early in my parenting career that “Children will teach you everything you need to know”. Being a mother is being raised. Our children become our advisers. Their dreams become our professors, as we are taking notes carefully. The sounds of their laughter and smiles on their faces are a great reward to us or bring us great joy. Their tears remind us that it is okay to fail, wipe the tears away and try again.
1.What did the old teacher mean by saying “There will always be a John”?
A. There are always difficult students like John.
B. John will always be an ordinary student.
C. It is important to change John.
D. John is a very common name.
2.What did Elaine West’s mother advise her to do?
A. Don’t treat students differently.
B. Take care of janitors.
C. Respect people from different backgrounds.
D. Don’t judge people by appearance.
3.Which of the following would Jan Davis most probably agree with?
A. A mother should be given more care.
B. A mother improves herself greatly in parenting.
C. Being a mother has more challenges than rewards.
D. Children should realize the dreams of their parents.
4.The text is most probably a(n) .
A. notice inviting contributions. B. introduction to a contest.
C. ad for three new books. D. poster about a lecture.

Their cheery song brightens many a winter's day. But robins(知更鸟) are in danger of wearing themselves out by singing too much. Robins are singing all night一 as well as during the day, British-based researchers say.
David Dominoni, of Glasgow University, said that light from street lamps, takeaway signs and homes is affecting the birds' biological clock, leading to them being wide awake when they should be asleep.
Dr Dominoni, who is putting cameras inside nesting boxes to track sleeping patterns, said lack of sleep could put the birds' health at risk. His study shows that when robins are exposed to light at night in the lab, it leads to some genes being active at the wrong time of day. And the more birds are exposed to light, the more active they are at night.
He told people at a conference, "There have been a couple of studies suggesting they are increasing their song output at night and during the day they are still singing. Singing is a costly behaviour and it takes energy. So by increasing their song output, there might be some costs of energy."
And it is not just robins that are being kept awake by artificial light. Blackoiids and seagulls are also being more nocturnal. Dr Dominoni said, "In Glasgow where I live, gulls are a serious problem. I have people coming to me saying `You are the bird expert. Can you help us kill these gulls?'.During the breeding(繁殖)season, between April and June, they are very active at night and very noisy and people can't sleep."
Although Dr Dominoni has only studied light pollution, other research concluded that robins living in noisy cities have started to sing at night to make themselves heard over loud noise.
However, some birds thrive(兴旺)in noisy environments. A study from California Polytechnic University found more hummingbirds in areas with heavy industrial machinery. It is thought that they are capitalizing on their predators(天敌)fleeing to quieter areas.
1.According to Dr Dominoni's study, what causes robins to sing so much?
A. The breeding season.
B. The light in modem.
C. The dangerous environment.
D. The noise from heavy machinery.
2.What is the researchers' concern over the increase of birds' song output?
A. The environment might be polluted.
B. The birds' health might be damaged.
C. The industry cost might be increased
D. The people's hearing might be affected.
3.What does the underlined word "nocturnal" in Paragraph 5 mean?
A. Active at night.
B. Inactive at night.
C. Active during the day.
D. Inactive during the day.
4.Why do some birds thrive in noisy environments?
A. Because there are fewer dangers.
B. Because there is more food to eat.
C. Because there is less light pollution
D. Because there are more places to take shelter.

Many of us are interested in time travel and shuttling back and forth (来回地) to the past or the future. Who wouldn’t be enthralled by returning to the past or seeing the future? But time travel seems to be possible onl
y in our imagination or in science fiction (科幻小说).Science fiction is a world where impos
sible things can become possible and that’s why most of us like it. But science fiction is not entirely fiction since it is based on science theories (理论). Time travel, for instance, is a theme used by sci-fi writers. Readers may sometimes think writers have first-hand experience of it. I have collected some of the popular ways in which time travel is made possible in science fiction:● Through the wormhole — A wormhole is a path between points in space-time. According to Einstein, an object can pass through a wormhole if it can travel at the speed of light. An example of a wormhole is described in Riddle of the Red Bible.
● Through a black hole — A black hole is a vacuum (真空) in space where light cannot even escape or pass through. In some sci-fi movies, like Star Trek, black holes became the means to travel through time.
● Through time machines — In science fiction, time machines are vehicles that can travel faster than light. It can be a strange vehicle like the TARDIS in Doctor Who or a special car like the one used in Back to the Future. But these special vehicles would need a wormhole to travel to the past or the future.
● Through parallel universe (平行宇宙) — Another popular way to travel through time is to be able to get into a parallel universe where one can go back to a point in time and see a different reality.
Though we know time travel may not be possible, it is still an entertaining subject and a heated topic for most of us. And in science fiction, where reality is always in the imagination, time does not really matter.
1.The underlined word “enthralled” in Paragraph 1 probably means “_____”.
A. defeated B. confused
C. s
hocked D. attracted2.What
can we learn from the passage?A. Time travel might become possible in the far future.
B. Time m
achines can’t travel to the past or the future without a wormhole.C. Sci-fi writers have similar experiences to those they describe in their fiction.
D. An object can travel to the past or the future when its speed is faster than light.
3.What is the author’s purpose in writing this passage?
A. To arouse the heated topic of time travel among readers.
B. To introduce how humans travel through time in sc
ience fiction.C. To introduce the author’s knowledge of time travel to the readers.
D. To compare different ways of time travel mentioned in some science fictions.
