Camels are large animals living in dry areas. There are two species of camels; the Arabian camel with a single hump(驼背) from the dry desert areas of West Asia, and the Bactrian camel with two humps from Central and East Asia. Camels are over 7 feet tall and weigh over 1,600 pounds. They will live up to 40 to 50 years. Most camels are domesticated(驯化) and fed by people. Camels are plant-eaters．

Camels are very strong animals with wide, padded feet. They have thick leathery pads on their knees and chest. Camels have nostrils(鼻孔) that can open and close, protecting them from the desert environment. Bushy eyebrows and two rows of long eyelashes protect their eyes from sand. Their mouth is extremely tough, allowing camels to eat thorny(带刺的) desert plants. Their widened feet help them move without sinking into the sand. Their thick coats reflect sunlight, and also protect them from the intense heat from desert sand. Their long legs help by keeping them further from the hot ground.

Camels can go without food and water for 3 to 4 days. They do not store water in their humps as is commonly believed．The humps are actually a container of fat. Camels are incredibly well-adapted to their environment. When conditions heat up, camels can increase their own body temperature, which prevents sweating and therefore water loss. They may not sweat at all during the day.

Camels are sometimes called “ships of the desert” because people ride them around the hot, dry deserts of the world. However, the number of camels is becoming smaller for various reasons.

1.According to the passage, camels usually live in ________.

A. Asia　　 B. Africa

C. America　　 D. Australia

2.Paragraph 2 is mainly about ________.

A. camels are useful animals

B. camels are clever animals

C. camels’ body structure and function

D. camels’ characteristics and habits

3.The reason why camels lose little water in deserts is that they ________.

A. get water from green foods

B. can adjust their temperature

C. store enough water in the humps

D. can manage without water

4.What will the author probably talk about following the last paragraph?

A. Ways to protect camels.

B. Habitats of camels.

C. Reasons for raising camels.

D. Functions of camels.

Frogs are animals that can live both in water and on land. There are more than 5,000 kinds of frogs on the earth. The earliest known frogs lived about 190 million years ago and the frogs today still look the same. Here are some fun things that you might not know about frogs. Enjoy!

The Biggest and the Smallest Frogs

Some frogs can be very big. The biggest kind of frog is the Goliath Frog in West Africa. Its body can be nearly 30cm long, about the size of a large cat. The Gold Frog and the Poison Frog are the smallest frogs in the world. They are less than 1cm long. Though the Poison Frog is very small, it is not weak at all. It is dangerous. Any animal that eats it will die very soon.

The Best Jumpers

Frogs are very good at jumping. They developed jumping legs so that they would not be eaten by other large animals. Using their big strong legs, more frogs can jump over 20 times their own length. It is like a person jumping over about 30,48. The Australian Rocket Frog can even jump over 2m, which is 50 times its body length(5.5cm). That might be the reason why frogs are called the best jumpers on the earth.

The Cryogenic Animal

Some frogs like the Common Wood Frog have a special ability to live in very cold places. When the temperature goes down, they become ice frogs. 2/3of their body water freezes. Their hearts stop, and their breathing stops too. You may think they are dead, but in fact they are not. Maybe we humans can learn the way that the frogs do for medical purpose.

1.The earliest frogs lived about ________ million years ago.

A. 20  B. 30   C. 50   D. 190

2.The Gold Frog is one of the ________ frogs on the earth.

A. smallest   B. biggest   C. strongest   D. weakest

3.________ can jump over 2m.

A. The Goliath Frog   B. The Common Wood Frog

C. The Poison Frog   D. The Australian Rocket Frog

The US plans to extend its endangered species protection to lions in Africa. US Fish and Wildlife Service (FWS) will classify lions in southern and eastern Africa as threatened. The move will place tighter restrictions on the import of lion “trophies(纪念品)”, such as paws or heads.

While the US cannot regulate hunting in other countries the move is significant because around half of all lion hunting in Africa is conducted by Americans. According to FWS data, more than 5, 600 lions have been killed and imported by American hunters over the past decade.

Under the new FWS rules, bringing lion parts to the US will be banned(禁止) in most circumstances if the animal is from a country where lions are endangered. Hunters will have to show the trophies were “legally obtained” from countries that have a scientifically sound management program that benefits the subspecies in the wild.

This regulation is expected to place a far greater burden of proof upon hunters who claim that the money from lion hunting has been used to help communities in Africa and the overall conservation of lions. The persistent downward trend in lion numbers, due to habitat loss and hunting by locals and foreign tourists, suggests there has been little conservation(保护) benefit from organized hunts.

An international study, published in September, found African lion numbers have decreased by half since 1993, with a further 50% decline expected over the next 20 years for populations in west, central and east Africa.

“The lion is one of the planet’s most beloved species and an irreplaceable part of our shared global heritage,” said Dan Ashe, director of the FWS. “If we want to ensure that healthy lion populations continue to wander around the African savannas(大草原) and forests of India, it’s up to all of us—not just the people of Africa and India--to take action.”

1. Why is the move of US significant?

A. The lions have been killed and imported by American hunters.

B. That is due to habitat loss and hunting by locals and foreign tourists.

C. Around half of all lion hunting in Africa is conducted by Americans.

D. The money from lion hunting has been used to help communities in Africa .

2. Where do most of the lion hunters come from?

A. Southern Africa.　　　　 B. America.

C. Eastern Africa.　　　　 D. India.

3. What may be the result of the move?

A. The import of lion parts will be strictly limited.

B. Lion-hunting will be illegal all over the world.

C. communities in Africa will benefit a lot.

D. Lion parts will never be legally obtained.

4. What does Dan Ashe really want to tell us in the last paragraph?

A. Almost everybody loves lions.

B. It’s everyone’s duty to protect lions.

C. Lion populations will increase rapidly.

D. Measures must be taken to keep lions fit.

The insects are important to farmers. When a honeybee lands on a flower in plant, pollen (花粉) sticks to its legs. When the bee lands on another flower, some of the pollen falls off and fertilizes the second plant.

The act of spreading pollen is responsible for many fruits, vegetables, nuts and other crops. Yet about 30 percent of honeybees in the United States and other areas have died in recent years.

Mike Leggett is a researcher at the University of Maryland. He wants to learn why so many bees are dying. “The number of colonies (蜂群) that die every winter has been one in three. So on average 30 percent of the colonies have died every winter over the last six winters. And that’s a huge number.” His research team examined the pollen that honeybees carried to their homes. They found that the pollen contained high levels of 35 different pesticides (杀虫剂), which are chemicals used to protect plants. “Pesticides are used, and have been used, pretty widely, for centuries, to protect plants from diseases,” says Mr Leggett.

Keith Oh linger, a farmer and beekeeper in Maryland, has watched many of his bees die every winter. Mr Ohlinger thinks widespread bee death is caused by several things happening at once. But he does not feel sure that pesticides are a part of the problem, “I felt it was the result of a lot of little things. I didn’t feel that there was probably one smoking gun. But there’s a division (分歧) there, some people feel that it is just one thing.”

Honeybees are important to agriculture. This makes the search for an answer to their death very important for Mr Leggett’s team. As he knows, one in every three bites of food we eat is somehow pollinated by honeybees.

1.What could be a suitable title for the text?

A. Why Are Honeybees Important?

B. How Do Honeybees Make Honey?

C. Pesticides Might Harm Honeybees

D. Honeybee Protection in Maryland

2.How does Mr Leggett sound in paragraph 3?

A. Worried.　　 B. Happy.

C. Surprised.　　 D. Hopeful.

3.We know from the fifth paragraph that Keith Ohlinger ________.

A. has become rich by keeping bees

B. cares little about the death of his bees

C. has never used pesticides on his farm

D. doubts whether pesticides have killed his bees

4.In which part of a website can we most probably read the text?

A. Agriculture.　　 B. Health.

C. Food.　　 D. Technology.

Penguins are flightless birds that spend half their time on land and half in the water.

1. They have dark and white feathers, and their wings have evolved into flippers (脚蹼). Most penguins feed on fish, squid and other forms of sea life caught while swimming.

2. They are mostly found in groups that include thousands of penguins. Penguins each have their own unique mating call, and they use that to locate their mate and chicks in such a large group.

Although almost all penguin species are native to the Southern Hemisphere, they are not found only in cold Antarctica.3. Several species are even found in the temperate zone, and one species, the Galátpagos penguin, lives near the equator (赤道).

Unfortunately, many penguin species worldwide are facing threats. The biggest is climate change and global warming. As the earth warms up, the sheets of ice have melted, and the algae (藻类)that grow under the ice decrease. The algae are eaten by tiny creatures called zooplankton. When there is a drop in zooplankton, it affects the fish that depend on it.4.

Another major threat is from oil spills. If coated with oil, penguins cannot float or swim in water. Also, if oil is swallowed, penguins will die from poison.5.

A.These birds are very social.

B.In fact, only a few of them live so far south.

C.Penguins are highly adapted for life in the water.

D.The biggest threat for penguins comes from humans.

E.They have a tendency to live in a community together.

F.As a result, penguins have less fish to eat and thus starve.

G.Others include overfishing, illegal egg harvesting, and natural enemies.

Living in a foreign culture there are many times when I realize that my perspective (观点) on life is drastically different from those Koreans I interact (相互影响) with on a daily basis. This past week I have been greatly challenged to change my perspective and here is why.

My dream in life is to become a doctor, one who changes the world. But last week I opened an email from UBC that contained the words “regrets”, no interview. I didn’t get an interview to medical school, thus will not be entering school for September 2009. My immediate reaction was one of extreme disappointment and anger—mostly directed at myself for not working hard enough, for not seeking out the opportunities necessary to have a good application, for simply not being good enough. My mind was full of hopelessness and despair that left me with no desire to further seek for the dream that I’ve held for quite a time now.

During the past week two things happened. At church our pastor mentioned perspective in a section of his sermon (说教). He stated that when we take our eyes off ourselves and realize God’s greatness, our circumstances will be seen through a new perspective.

The second thing that reminded me to look at perspective was reading a book. The Mitford Series is so good if you are looking for books to read. So last night I was reading and one of the main characters (who is a priest) is trying to figure out what to say at church. His sermon ended up saying “In everything we give thanks.” It is easy to give thanks when we feel successful in life. It is easy to give thanks when we receive a blessing. But seriously, who in their right mind says thanks for the financial problems I have?

1.Where does the author probably live now?

A. In the USA.        B. In Britain.          C. In China.                      D. In Korea.

2.How did she feel when the author received the email from UBC?

A. Surprised.                    B. Disappointed.             C. Excited.                          D. Pleased.

3.In the first pastor’s view, when we face disappointment or despair, we should _________.

A. turn to God for help                                                 B. say thanks to it

C. see it in another way                                                D. praise others for it

4.What can we infer from the passage?

A. The author can’t really free from the disappointment.

B. The author thinks the second sermon is wiser.

C. The author still wants to be a doctor.

D. The author thanks God for not being admitted by the university.

Today, over six billion people live on the planet. This means that there are very few places on Earth with no people. One place that has very few people is at the bottom of the Earth. In Antarctica, the icy continent surrounding the South Pole, you will not find anyone who lives there all the time.

First, Antarctica is the coldest place on Earth. For example, it can be –l30℃ in the winter. Humans cannot live in this kind of environment. Because it is so cold, very few plants or animals live there. This means there are no farms and no places to find wild plants or animals to eat.

Second, Antarctica can be dangerous. Many people think that it is safe to travel to Antarctica in the summer months when it is warmer. However, Antarctica is mostly ice, so when it’s summer, the ice melts. When the ice melts, the ice can break. So, people cannot travel around Antarctica during the summer. If the ice breaks, they could fall into the water and die.

Another serious problem in Antarctica is the sun. Because Antarctica is mostly ice, there are no trees so there is no shade. Also, the ground is mostly white ice so the sun bounces off (反射) it. The light from the sky and the light from the ground can burn people’s skin and hurt their eyes. People must be very careful in this situation. For example, they must wear sunglasses to protect their eyes. They must also cover their hands and faces all the time.

Although Antarctica is a tough place to live, explorers have discovered coal in Antarctica. This leads them to believe that Antarctica at one time was a land of swam (沼泽) and forests.

1.This text is mainly about _____.

A. the discovery of Antarctica

B. how people travel around Antarctica

C. different animals found in Antarctica

D. why it is difficult to live in Antarctica

2.We can learn from the text that _____.

A. Antarctica is a place with no animals

B. no people can survive in Antarctica

C. Antarctica is colder than any other continent on Earth

D. the temperature in Antarctica is below zero all the time

3.When is the most dangerous time to travel around Antarctica?

A. In spring. B. In summer.   C. In autumn.   D. In winter.
