Snow falls in the Earth’s extreme North and S...

Snow falls in the Earth’s extreme North and South throughout the year. However， the heaviest snowfalls have been reported in the mountains of other areas during winter. Snow is even known to fall near the Equator (赤道)，but only on the highest mountains.

Snow contains much less water than rain, but much of the water the world uses comes from snow. Melting snow provides water for rivers, electric power stations and agricultural crops. In the western United States, mountain snow provides up to seventy-five percent of all surface water supplies.

Snowfall helps to protect plants and some wild animals from winter weather. Fresh snow is made largely of air trapped among the snow crystals (晶体). Because the air has trouble moving, the movement of heat is limited. Snow also influences the movement of sound waves. The surface of the snow takes in, or absorbs, sound waves. As snow grows older or if there have been strong winds, it can become hard and flat. Then, the snow，s surface will help to send back sound waves.

Snow may be beautiful, but it can be deadly. It is responsible for the deaths of hundreds of people. Many people die in traffic accidents on roads covered with snow and ice or from being seriously stuck in the winter storm. Others die from heart attacks caused by too much physical activity out in the cold.

People may not be able to avoid living in areas where it snows often. However, they can avoid becoming victims of snowstorms. People should stop driving and stay at home until the storm has passed. People living in these areas should carry emergency supplies in their vehicle. These include food，emergency medical supplies，and extra clothing to stay warm and dry.

In the famous fairy tale, Snow White eats the Queen's apple and falls victim to a curse（诅咒）;in Shakespeare's novel, Romeo drinks the poison and dies; some ancient Chinese emperors took pellets（药丸）that contained mercury（水银）, believing that it would make them immortal, but they died afterward.

Poison has long been an important ingredient in literature and history, and it seems to always be associated with evil, danger and death. But how much do you really know about poison?

An exhibition, The Power of Poison, opened last month at the American Museum of Natural History in New York, intended to give the audience a more vivid understanding of poison.

The museum tour starts in a rainforest setting, where you can see live examples of some of the most poisonous animals: caterpillars（毛毛虫）, frogs and spiders. Golden poison frogs, for instance, aren't much bigger than a coin, but their skin is covered with a poison that can cut off the signaling power of your nerves, and a single frog has enough venom to kill 10 grown humans.

"Poisons can be bad for some things," Michael Novacek, senior vice president of the museum, told NBC News. "Yet they can also be good for others."

A poisonous chemical found in the yew tree is effective against cancer, which is what led to the invention of a cancer-fighting drug called Taxol.

The benefits from natural poisons are not limited to just medicine. Believe it or not, many substances（物质）that we regularly ingest（摄入）-chili, coffee and chocolate-owe their special flavors or stimulating（提神的）effects to chemicals that plants make to poison insects.

1.What does the underlined word "immortal" in Paragraph 1 mean?

A. happy　　 B. not moral

C. living forever　　 D. sick

2.What is the main purpose of the exhibition The Power of Poison?

A. To give people more in-depth knowledge about poison.

B. To teach people how to handle poisonous animals.

C. To inform people about which animals are the most poisonous.

D. To show how poison has been used for medical treatment.

3.Which of the following statements about the Golden poison frog is TRUE according to the article?

A. Its skin can cut off the signaling power of your nerves.

B. It's about the size of a coin.

C. It's the most poisonous animal on display.

D. You can only see it in a rainforest setting of the museum.

4.The stimulating effects of coffee come from ________.

A. natural poison made by the plant

B. the substances that we regularly ingest

C. chemicals produced by poisonous insects

D. its special flavor

The black and white bird came ashore on a beach in the south of the North Island nearly 4,000 miles away from its usual habitat. The creature’s astonishing journey was witnessed by a woman walking her dog as the two-foot bird waddled out of the water in front of her. She said, “It was out of this world to see it. It was this glistening white thing standing up on the sand and I thought I was seeing things.” The tale of the lost penguin is similar to the 2006 children’s film Happy Feet, in which a young penguin finds himself far from home during a voyage of discovery.

Conservationists believe it has completed an incredible journey for such a young bird — it is estimated to be around 10 months old. The most likely explanation for its appearance in New Zealand is the hunt for food. Experts said it may also have rested on an ice floe (浮冰) during its travels and was carried north for a great distance before it made a swim for dry land. Colin Miskelly, a curator of New Zealand Museum, said, “They can spend months at a time in the ocean and come ashore only to moult (脱毛,换毛)or rest.” Mr. Miskelly said the brave bird would have to find its way back south soon if it was going to survive. He said, “It is probably hot and thirsty and has been eating wet sand.” “It doesn’t realize that the sand isn’t going to melt inside it because they typically eat snow — their only liquid.”

New Zealand residents have been warned to give the bird a wide berth — it can inflict (予以) painful bites if threatened.

1.Which of the following is True of Paragraph 1?

A．A young penguin found himself far from home during a voyage of moulting.

B．A creature’s astonishing journey was incredible in the north of the North Island.

C．A woman witnessed a 2 feet bird waddled in the children’s film while walking her dog.

D．A penguin came ashore on a beach thousands of miles away from its habitate.

2.Conservationists tend to explain that____________.

A．the young bird has completed a pleasant journey of 4,000 thousand miles

B．the young bird’s appearance in New Zealand is due to its hunt for food and delay of returning

C．the young bird comes ashore in New Zealand only to moult or rest during its voyage

D．the young bird is certain to be over 10 months old when it appears on a beach

3.What do we know about the penguin according to Mr. Miskelly?

A．The penguin could spend months at a time in the ocean and came ashore only to have young ones.

B．The young bird might have slept on an ice floe and could not swim for dry land.

C．The young penguin didn’t realize the sand wasn’t going to melt inside it like snow it eats.

D．The brave bird would have to find its way back north soon if it was going to survive.

4.What does the underlined part mean in the last sentence?

A．The residents should keep well away from it when they want to watch the young penguin.

B．Some people do not realize the danger of the young bird and they are expected to touch it.

C．New Zealand residents want to keep the young bird but it wants to leave the shore.

D．If the local people threatened the young bird, it would do harm to other birds nearby. .

The mass death of flying foxes in extreme heat in North Queensland last month underlines the importance of University of Queensland wildlife research released today.The UQ research sheds light on how various species have responded to major climate events.

A study led by UQ School of Earth and Environmental Science researcher Dr Sean Maxwell has spent more than 70 years quantifying the responses of various species.

“The growing frequency and intensity of extreme weather events such as cyclones, droughts and floods is causing unpredictable and immediate changes to ecosystems and blocking existing management efforts,” Dr Maxwell said.“Some of the negative responses we found were quite concerning, including more than 100 cases of dramatic population declines and 31 cases of local population extinction following an extreme event.”

"Populations of critically endangered bird species in Hawaii, such as the palia, have been annihilated due to drought, leaving none of its kind, and populations of lizard species have been wiped out due to cyclones in the Bahamas."

Cyclones were the most common extreme event for birds, fish, plants and reptiles, while mammals and amphibians were most responsive to drought events, with drought leading to 12 cases of major population decline in mammals.Drought also led to 13 cases of breeding declines in bird populations and 12 cases of changes in the composition of invertebrate communities.

UQ Centre for Biodiversity and Conservation Science director Professor James Watson said the detailed information would help inform ecosystem management.

“The research clearly shows species will respond, often negatively, to extreme events,” Professor Watson said.“As climate change continues to ensure extreme climate and weather events are more and more common,we now need to act to ensure species have the best chance to survive.Wherever possible, high quality and intact habitat areas should be retained, as these are the places where species are most resilient(易恢复的) to increasing exposure to extreme events.”

1.How was the UQ researchconducted?

A. By observing extreme weather events.

B. By protecting the endangered species.

C. By recording reactions of animals to extreme climate.

D. By analyzing the reason why mass animal death happened.

2.What does the underlined word “annihilated” in paragraph 4 probably mean?

A. destroyed B. defeated

C. decreased D. disappeared

3.Which of the following sentences is true about extreme weather events?

A. Drought caused 13 cases of distinctionin bird populations.

B. Drought caused 12 cases of population decline in mammals.

C. Birds and mammals are most responsive to cyclones.

D. Cyclones wiped out populations of lizard.

4.What can we infer from Professor Watson’s words?

A. Animals often show negative responses to extreme events.

B. The existing management ways for wildlife protection are limited.

C. Different methods should be adopted to ensure the survival of different species.

D. Complete and undamaged habitats are of great importance to species’ survival.

Botswana lies immediately to the north of South Africa. It is bordered on the north and west by Namibia, on the north and east by Zimbabwe, and is connected by a narrow strip of land on the northern border to Zambia. Its territory consists almost entirely of a broad, flat, arid subtropical plateau(高原), though there are hills in the eastern part of the country.

In the northwest, the Okavango River empties into the Kalahari sands, creating the largest inland river delta in the world. While the Okavango Delta is home to relatively few large animals in comparison to other areas of Botswana, its clear waters and countless small islands are home to a variety of birds, plants, and smaller species of animals.

Nearby is Chobe National Park, a beautiful grassland reserve(保护区) that has gained international fame for its large elephant population. Southeast of Chobe are Botswana's large Makgadikgadi salt pans, home to numbers of blue wildebeest, several antelope species, and those international lovers of salt pans, flamingos(a kind of birds).

Almost the entire remaining portion of the country is covered by the Kalahari Desert--a varied environment of sand and grassland. Although this area of Botswana is where few people live, it is one of the richest wildlife areas in all of Africa.

Botswana's two largest parks, the Central Kalahari Game reserve and Gemsbok National Park, are found in this region.

Botswana's climate can get rather cool, particularly during the dry winter months of June to August when night occasionally brings frost. The rainy summer months (December through March) are best avoided for those interested in enjoying the best game viewing conditions.

72.South Africa is to the______of Botswana.

A.east     B.north   C.south   D.west

73.In the Okavango Delta we can find______.

A.a lot of large animals         B.many small islands

C.salt pans             D.polluted waters

74.If we want to see flamingo, we should go to_______ .

A.salt pans             B.Chobe National Park

C.Kalahari Desert          D.Gemsbok National Park

75.It is suggested that tourists visit Botswana in______.
