There are 115 distinct（独特的）species of pine trees with 35 native to North America. Pines are defined as evergreens with long, needle-like leaves and are only native to the northern hemisphere. Pine trees are an adaptable and tough species that can survive in many conditions where other plants cannot. The average pine is 45 to 60 feet tall, but some are nearly twice as high.
Western White Pine
The western white pine grows the tallest of any pine tree, reaching up to 110 feet in height. They have blue-green needles arranged in bundles（束）of five and produce a long cone（球果）.
Bristlecone Pine
The bristlecone pine grows slowly, reading about 20 feet tall. It is one of the oldest species of pine.
Mexican Pine
The Mexican pine can grow to 50 feet tall, with long, slender needles that drape（下垂）off it like a weeping willow（柳树）. Often nicknamed the “willow pine”, it is native to Mexico. Its leaves can droop up to 12 inches long.
Sugar Pine
The sugar pine is another of the large pine species, such as the bull pine, but it also has the largest cones of any pine species, at 10 to 20 inches long. It grows from Oregon to California and is often used for construction.
Jack Pine
The jack pine is one of the smallest species of pine with rare leaves. Compared with the pines mentioned above, it doesn’t seem to belong to the family. It is considered a member of the scrub-pine family; it prefers sandy soil.

There are more species of beetles than any other form of life. About 380 000 species of beetles are known to exist, and more are discovered all the time. There are several theories about why there are so many beetles, but fossils evidence shows that beetle species die out less than other animals, Beetle species exist in such huge number because beetles are true survivors. They refuse to die out.
One of the reasons beetles survive so well is their body design. Most beetle species have two pairs of wings. The front pair of a beetle’s wings are hard and thick. They are not used for flying. These protect the back set of wings and the beetle’s stomach. Instead, some species of beetles have lost the ability to fly, but they are still equipped with front wings. The wings protect the beetle’s soft parts from harm. These features help protect beetles, which makes them less likely to die out if they are faced with new predators (捕食性动物).
Beetles can also eat a wide range of foods. Beetle species live all over the world, and they have many different types of food available to them. Most beetles are omnivores. That means they eat both plants and animals. Their mixed diets help beetles adapt to many different habitats. Over the course of time, food sources, like certain plants and animals, do not exist anymore. Others spring up. The beetle survives because it can find something to eat, no matter what.
Finally, beetles are good at moving quickly over long distance. Any change in an animal’s environment can be dangerous to it. For example, many species died out during the Ice Age, when Earth’s temperature dropped for a long time. However, some species can avoid dangerous environment changes by moving to a new place. Research shows that beetles respond quickly to shifts in temperature. They can move to safer environments.
Beetles’ bodies and habits help give them an edge over other creatures. They are unlikely to die out. As a result, beetles make up nearly one quarter of all animal species. There are more types of beetles on Earth than there are types of plants. Some types of beetles that exist today were around during the Permian period of history, 284 million years ago. Beetles, clearly, are here to stay.
1.What is important about a beetle’s front wings?
A.They are used to catch the prey.
B.They enable the beetle to fly.
C.They help the beetle move quickly.
D.They protect the soft body parts.
2.How do beetles respond to changes of habitats?
A.They are adaptable to the food change.
B.They can change their body temperature.
C.They are adaptable to the freezing cold weather.
D.They can use their wings to fight against the cold.
3.What is the most probable title of the passage?
A.The Ice Age affected the beetles
B.Different habitats affected the beetles
C.Beetles: the six-legged survivors
D.Beetles: the unique predators

Sharks have lived in the oceans for over 450 million years. There are now about 360 species of sharks, whose size, behavior, and other characteristics differ widely.
Sharks range in size from the 0.1 meter long dwarf-dog shark to the 18-metre long whale shark — the world’s biggest fish. The whale shark, like two other large shark species — the basking shark and the megamouth shark — are harmless to people because they feed on plants and small aquatic animals.
Sharks have extremely sensitive sense organs. Some sharks can detect the scent(气味) of decaying fish or blood even when it is diluted(稀释) to only one part per million parts of seawater. They can probably hear underwater sounds that originate as far as 3 kilometers away and can tell the direction from which underwater sounds are coming.
Sharks are key predators(肉食动物) in the world’s oceans, helping control the numbers of many other ocean predators. Without sharks, the oceans would be overcrowded with dead and dying fish.
Every year, we catch and kill over 100 million sharks, mostly for food and for their fins. Dried shark fins are used to make shark fin soup, which makes a profit for the sellers. Other sharks are killed for sport and out of fear. Sharks are vulnerable to overfishing because it takes most species 10 to 15 years to begin reproducing and they produce only a few offspring.
Influenced by movies and popular novels, most people see sharks as people-eating monsters. This is far from the truth. Every year, a few types of sharks injure about 100 people worldwide and kill about 25. Most attacks are by great white sharks, which often feed on sea lions and other marine mammals. They sometimes mistake human swimmers for their normal prey, especially if they are wearing black wet suits.
If you are a typical ocean-goer, your chances of being killed by an unprovoked(无缘无故的) attack by a shark are about 1 in 100 million. You are more likely to be killed by a pig than by a shark.
Sharks help save human lives. In addition to providing people with food, they are helping us learn how to fight cancer, bacteria and viruses. Sharks are very healthy and have aging processes similar to ours. Their highly effective immune system allows wounds to heal quickly without becoming infected, and their blood is being studied in connection with AIDS research.
Sharks are among the few animals in the world that almost never get cancer and eye cataracts. Understanding why can help us improve human health. Chemicals extracted from shark cartilage(软骨) have killed cancerous tumors in laboratory animals, and these chemicals may someday help prolong our life.
Sharks are needed in the world’s ocean ecosystems. Although they don’t need us, we need them. We are much more dangerous to sharks than they are to us. For every shark that bites a person, we kill one million sharks.
1.Which statement best expresses the main idea of the article?
A. There are many different species of sharks, but only a few of them are dangerous to humans.
B. Sharks are important to the ocean ecosystem and they are a valuable resource for humans.
C. Although some sharks are dangerous to humans, they can help save human lives.
D. Sharks always eat small fishes and they are an essential part of the world’s oceans.
2.Which question is NOT answered in the article?
A. How long does a shark live?
B. How many people are killed by sharks each year?
C. Why are sharks important in medical research?
D. What do humans kill sharks for?
3.It can be inferred from the passage that ______________.
A. movies have given people the wrong impression of sharks
B. most sharks are dangerous to humans
C. sharks will attack anyone who is wearing black
D. it is very likely that ocean-goers will be killed by a shark

The tradition of having a pine tree as a Christmas Tree is believed to come from Germany. Since the medieval time, lighting a candle on a tree is common to welcome guests. Such practice has evolved into the Christmas celebration.
The formal Christmas Tree was introduced to England about 100 years ago when Queen Victoria married German Albert. The evidence of Victoria's love for Albert is not only expressed through inheriting the German tradition of having a Christmas Tree but also through the gold Albert Statues that Victoria had ordered to built for Albert, standing in many places in London. In America, the Christmas Tree idea was brought by German immigrants too.
The custom of sending Christmas cards was initiated in England around 1850. The first cards were decorated with elaborate designs of flowers, birds and landscapes.
As for Saint Nicholas, or Santa Claus, the story goes back to the third century.
Legend has it, Saint Nicholas dedicated all his life to helping mankind, especially children. He died on December 6, which marks the Saint Nicholas Day in many European countries and that was when gifts were given to children. Saint Nicholas bears many different names, such as Father Christmas in the UK, San Nicolas in the Netherlands, Le Pere Noel in France, and Kriss Kringle in Germany.
He also arrives on different dates to deliver presents to children in different countries, typically from chimneys. The chimney story was this: Santa flew over house tops in a sleigh, he dropped coins by accident and they landed in some stockings hanging next to the fireplace to dry. From then on, red stockings were hung by the chimney in hopes that Santa would fill them with gifts.
1.The passage is most probably taken from ______.
A. a history book B. a geography book
C. a folk story book D. a book on culture
2.Which of the following descriptions about Santa Clause is NOT right according to the passage?
A. In the UK, Santa Claus is Father Christmas.
B. Santa Claus usually delivers presents to children through chimneys.
C. Santa Claus became known to the British about 170 years ago.
D. Santa Claus was devoted to helping mankind.
3.We can infer from the passage that ______.
A. England is the birthplace of pine trees
B. Santa Claus was very popular among children
C. it was the Germans who brought the Christmas tree to the United states
D. Santa Claus is someone only existing in people’s imagination
