A tropical fish that lives in mangrove swamps(濕地) across the Americas Can survive out of water for months at a time,similar to how a11iIlals adapted to land millions of years ago。a new study shows.
The Mangrove Rivulus,a type of small tropical killifish。seeks refuge in shallow pools of water in crab Caves,nut shells or even old beer cans in the tropical mangrove swamps of Belize,the United States and Brazil.
When their living place dries up,they group together on the land in hollowed logs(圓木)and breathe air through. their skin instead of their gills (腮) until they can find water again.The fish,whose scientific name is Rivulus Marmoratus,can grow as large as three inches.
The scientific breakthrough came after a trip to Belize.
“We kicked over a log and the fish just came dropping out,”Taylor told Reuters in.neighboring Guatemala by telephone.He said he will publish his study on the fish in The American Naturalist journal early next year.
In lab tests,Taylor said he found the fish Can survive for up to 66 days out of water without eating, and their metabolism(新陳代謝) keeps functioning.
Some other fish Can survive briefly out of water.The walking catfish found in Southeast Asia call move about over land for hours at a time,while lungfish found in Australia,Africa and South America can survive out of water,but only in a sleeping state.
No other known fish Can be out of writer as long as the Mangrove Rivulus and remain active.a(chǎn)ccording to Patricia Wright,a biologist at Canada’s University of Guelph.
“These animals live in an environment that is similar to conditions that existed millions of years ago,when animals began making the evolution(進(jìn)化) from water onto land,”she said.

When most people think of tropical islands, lined with white sandy beaches and bright blue seas, it is often the Caribbean or South Pacific that comes to mind. But for Chinese tourists who want a taste of paradise on Earth there is a new place to consider.
Mauritius, an island lying off the southeast of Africa in the Indian Ocean, has just been added to China’s list of tourist destinations. Rich in history, natural beauty and culture, the island has been a popular destination for the world’s tourists for many years.
On December 15 a total of eight African countries were added to the list. The others are Tunisia, Tanzania, Ethiopia, Kenya, Zimbabwe, Zambia and the Seychelles.
The island has passed through the controlling hands of a number of European powers, including Dutch, French and British. In 1968, Mauritius won its independence.
At present, over half the population of Mauritius is Hindu and another fifth is Muslim. Both groups are descendants(后裔) from workers brought to the island from India by the British. Some Chinese were also brought over to work. There are also descendants of African slaves and Franco-Mauritians, the original settlers of the island.
One of the best things about the island is the food. There is a mouth-watering mix of European, Chinese and Indian flavours and seafood is very popular. A typical Mauritian dinner might have Indian chicken curry, Chinese pork, British roast beef and French-style vegetables. Boiled rice is served with just about everything. All that is washed down with a plentiful supply of local beer and rum(朗姆酒).
The pleasant tropical climate and scenery provide the perfect setting to enjoy everything. The sea is full of colorful life that lives around the coral reef. This makes Mauritius a wonderful place for swimming and diving. The large number of interesting fish means it is also an exciting place for those who like to go fishing. (from www.nmet168.com)
5. Which of the following can’t be used to describe Mauritius?
A. Tropical island, white sandy beach and bright blue sea.
B. Beautiful scenery, rich history and culture.
C. Most of the people in Mauritius are black.
D. Delicious food mixed with eastern and western flavours.
6. Which group of the following topics is not discussed in the text?
A. Food and history. B. Scenery and population.
C. Location and sports. D. Natural resources and agriculture.
7. Which of the following is true?
A. Mauritius has something similar to the Caribbean or South Pacific.
B. Mauritius has a history of less than 40 years.
C. Mauritius has been a popular destination for Chinese tourists for many years.
D. The main food in Mauritius is local beer and rum.
8. The underlined word “This” in the last paragraph refers to ________.
A. Pleasant tropical climate B. Beautiful scenery
C. The sea with colorful life D. The coral reef

One reaction to all the concern about tropical deforestation(毀林) is a blank stare that asks the question, "Since I don't live there, what does it have to do with me?"
The answer is that your way of life, wherever you live in the world, is tied to the tropics in many ways. If you live in a house, wash your hair, eat fruits and vegetables, drink soda, or drive a car, you can be certain that you are affected by the loss of tropical forests.
Biologically, we are losing the richest regions on earth when, each minute, a piece of tropical forest, the size of ten city blocks, disappears. As many as five million species of plants, animals, and insects (40 to 50 percent of all living things) live there, and are being lost faster than they can be found and described. Their loss is immeasurable.
Take rubber for example. For many uses, only natural rubber from trees will do. Synthetics are not good enough. Today over half the world's commercial rubber is produced in Malaysia and Indonesia, while the Amazon's rubber industry produces much of the world's four million tons. And rubber is an important material in making gloves, balloons, footwear and many sporting goods. Thousands of other tropical plants are valuable for their industrial use.
Many scientists strongly believe that deforestation contributes to the greenhouse effect -- or heating of the earth from increased carbon dioxide in the atmosphere. As we destroy forests, we lose their ability to change carbon dioxide into oxygen.
Carbon dioxide levels could double within the next half-century, warming the earth by as much as 4.5 degrees. The result? A partial melt-down of polar ice caps, raising sea levels as much as 24 feet; even 15 feet could threaten anyone living within 35 miles of the coast. Unbelievable? Maybe. But scientists warn that by the time we realise the severe effects of tropical deforestation, it will be 20 years too late.
Can tropical deforestation affect our everyday lives? Now, you should have got the answer.
1.The underlined word "synthetics" probably means_________.
A. natural rubber B. tropical materials
C. man-made material D. commercial rubber
2.According to the passage, which of the following is NOT true?
A. The forests are losing their function in turning carbon dioxide into oxygen.
B. Many of our daily uses are related to the tropical forests.
C. Tropical plants can be used to make industrial products.
D. High carbon dioxide levels will make the earth warmer.
3.The author's attitude towards the tropical deforestation is _________ .
A. puzzling B. cold C. supporting D. opposed
4.Which of the following might be the best title for the passage?
A. Tropical Forests B. The Value of Tropical Forests
C. Tropical Forests and Our Life D. The Greenhouse Effects

Ten Chinese PhD students are demanding that Beijing Normal University Professor Yu Dan be away from her television show on CCTV10. They argue that her on-air explanations of Confucius’s Analects (孔子《論語(yǔ)》) are “incorrect and misleading”. Yu is known for explaining Confucius’s Analects to a TV audience. But some complain that her explanations are unfaithful to Chinese tradition. But Yu doesn’t seem to worry too much about her critics, saying, “It’s a matter of personal choice. Some like KFC, while others like McDonalds.” |
STEALING some online gamer’s password might seem less harmful than credit card theft. It does keep the victim from wearing himself out all night playing. But it is not all that nice, says 19-year-old Zhang Qiwen, in Shanghai. Last August, Zhang accidentally downloaded a Trojan while playing Warcraft. The Trojan is a type of virus used by hackers to steal people’s passwords. Overnight the Trojan transferred all the “gold” (game credits) from Zhang’s private account to an unknown account. Zhang hopes the police will find and punish the thief, who can also pocket some cash since the stolen “gold” can go on sale online. |
New England’s largest indoor public garden has opened here in a historic park, and officials expect it to become a center for learning about plants as well as a top attraction for visitors. The glass-walled Roger Williams Park Botanical Center, which opened on March 2, offers a tropical garden, an orchid garden, and a Mediterranean room with a collection of citrus trees. The center also has two classrooms and will offer gardening classes provided by the University of Rhode Island. Roger Williams Park, named for the city’s 17th-century founder, also has a zoo. The park already attracts more than 2 million visitors a year, and Providence Mayor David Cicilline said that he expects the new center will attract more and more visitors to Providence. |
1.Which of the following statements is true?
A. Confucius’s Analects is like KFC or McDonalds in China now.

The climate of any place is the kind of weather. It usually has over a long period of time. The houses we live in, the clothes we wear, the foods we eat depend on the climate of the place where we live.
Climate is a pattern that is not nearly as simple as we think, and it is affected by many factors. The distance to the North or South Pole(極,極點(diǎn),) or the equator (赤道) really matters a lot. If you live near either of the poles, you live in a cold climate, for the place where you live does not get as much or as direct sunshine as a place farther away from the poles. In places close to the equator, the climate is very hot, for they are the parts where the sunshines almost straight down.
Whether rain or snow falls makes a great difference to the climate. In hot, dry deserts, little rain falls, but in a hot rainforest, the amount of rainfalls is far larger than that in a desert, for there is a heavy rain almost every day, even several times per day. Though a rainforest and a desert may be the same distance from the equator, their climates are rather different from each other.
How much rain or snow falls are considered by some to be determined by the winds, the surrounding mountains and the currents(水流)in nearby seas and so on . In short, it is a very complex natural phenomenon(現(xiàn)象).
54.This passage mainly talks about .
A. weather B. different climates
C. climate and its determining factors D. the difference between weather and climate
55.The difference of the climates between a tropical (熱帶的)desert and a tropical rainforest affected by .
A. the amount of rainfalls
B. the winds and the surrounding mountains
C. the currents in near seas
D. how much sunshine the two different places can get
56. From the context, we can guess that the word “complex” is and it .
A. a noun; means a simple thing
B. an adjective; means being easy to understand
C. an adverb; has almost the same meaning of “rather”
D. an adjective; means being difficult to understand
