Wild animals (and wild plants) and the wild places where they live are seriously threatened almost everywhere. One species has become extinct in each year of this century. But many hundreds are now in danger. Lack of attention would lead to the rapid advance of the process of extinction.

But even more important, perhaps than individual kinds of animals and plants, whole habitats are in danger of vanishing: marshes are being drained, and the world forests, especially tropical forests are being cut down to satisfy man’s needs of timber and paper.

What would our world be like if all the wild animals and wild plants vanished? - Would our life still exist then?

1. What would happen to the human beings if the wild life vanished?

A. Many species would quickly become extinct.

B. The human life would be seriously threatened.

Everyone knows that honeybees make honey, but how do they actually do it? Honeybees live in colonies, which means that they live with lots of other bees. Beehives, nests made of wax, are the places where they live and stow their honey.

Honeybees drink nectar from flowers or other sweet deposits from plants or trees. The honey made by these bees is used to supply the colony with food during the cold winter when there arc no flowers to drink from. Thus, these bees not only consume the nectar for nourishment but also bring it home. They have a special organ called a honey stomach which is used to carry the food to their colony.

When honeybees come back home, they regurgitate what they have put in their honey stomachs. Other honeybees in the hive come along and help them. They repeatedly eat and regurgitate many times until the product becomes somewhat digested. Next, the bees move the syrupy product into open honeycomb cells. Then they beat their wings to fan it to prevent fermentation. The fanning makes the water evaporate so that the product gets thick enough. Now it cannot easily be attacked by bacteria. Finally, it can be called honey. After this process, honeybees seal up the honeycomb cells with wax until they are hungry.

The most impressive part of this process is how seamlessly a bee colony works together. In a colony, there are female worker bees, male drones, and one queen bee. Although there are both male and females in the hive, the majority of the work is done by females. The female worker bees are in charge of taking care of the hive and creating honey. When they are young, they take care of feeding the young bee larvae. When they are older, they go out and bring nectar back to the hive, where they begin making honey. The male drones are responsible for fertilizing the eggs, but require little energy as they spend their time waiting around the hive. The single queen bee is responsible for the colony's survival. She is the only female that can lay eggs. The wonderful substance called honey would not exist without the bees' teamwork.

1. What is the main topic of the passage?

A. The role of the female honeybee
B. Preventing fermentation in honey
C. Why honeybees build huge wax nests
D. How a honeybee colony works to make honey

2. What can be inferred from the passage about honey? A. It's not always the same color
B. It is only liked by a minority of people
C. Watery honey can go bad easily
D. It is created and cared for by the queen bee 3. What do honeybees do to prevent fermentation? A. Blow air on the honey by waving their wings
B. Overproduce honey using their legs
C. Feed the larvae the unfermented honey
D. Bring the honey to the honeycomb cells 4. According to the passage, which of the following is NOT true of honeybees? A. They work together in their colony.
B. They produce honey through a complex process
C. The queen bee is responsible for making honey
D The worker bees work both inside and outside of their hive.

Read the passage carefully, then choose the correct answer

The first system of communication of animals is natural. Many kinds of animals have ways of communicating with each other. And one of the most interesting examples is that of bees. These insects communicate with each other by dancing. The most important kind of dance that they do is concerned with food. They get their food from flowers, of course, from plants and trees. When a bee has found some food, it returns to the other bees and can give them three basic kinds of information about the food: which direction it is in, whether it is nearby or a long way away, and whether it is good to eat or poisonous.

The other kind of system of communication of animals is artificial. It means animals learn it; in this case, they learn from man. Several famous experiments have been carried out with chimpanzees, trying to teach them human language.

One of these experiments was done with a chimpanzee called Sarah. Sarah was taught to understand a system of symbols which represented words. The symbols were cut out of coloured plastic, and each different shape stood for a different word. For example, a red square stood for “banana”, Sarah’s favorite fruit. Soon Sarah could not only understand words, but even sentences. She could obey orders: if her human friends put down the symbols for “apple in cup”, she would put the apple in the cup. Later, she began giving the scientists orders – she was writing her own sentences, and she got upset if the scientists did not obey her. We do not yet know whether chimpanzees will ever learn to use language to communicate as freely as human beings do, but the results so far suggest that this is at least a possibility.

41) According to the passage, bees ____________________________________.

A. learn to communicate B. are born to be able to communicate

C. are the most interesting animals D. communicate with each other by flying

42) From the passage, we can conclude that bees are _____________________.

A. so selfish as to let other bees share the bad food

B. so selfish as to look for food for themselves

C. so hardworking that they dance all the time

D. so smart that they know where the food is

43) The experiment done with Sarah is an example of ____________________.

A. animals with natural system of communication

B. animals able to communicate with humans

C. animals possible to use language as humans

D. animals with a system of communication worked out by humans

44) The results of the experiment with chimpanzees show the possibility to teach animals _____.

Every drop of water in the ocean, even in the deepest parts, responds to the forces that create the tides. No other force that affects the sea is so strong. Compared with the tides, the waves created by the wind are surface movements feltno more than a hundred fathoms below the surface. The currents also seldom involve more than the upper several hundred fathoms despite their impressive sweep.

The tides are a response of the waters of the ocean to the pull of the Moon and the more distant Sun. In theory, there is a gravitational attraction between the water and even the outermost star of the universe. In reality, however, the pull of remote stars is so slight as to be obliterated by the control of the Moon and, to a lesser extent, the Sun. Just as the Moon rises later each day by fifty minutes, on the average, so, in most places, the time of high tide iscorrespondingly later each day. And as the Moon waxes and wanes in its monthly cycle, so the height of the tide varies. The tidal movements are strongest when the Moon is a sliver in the sky, and when it is full. These are the highest flood tides and the lowest ebb tides of the lunar month and are called the spring tides. At these times, the Sun, Moon, and Earth are nearly in line and the pull of the two heavenly bodies is added together to bring the water high on the beaches, to send its surf upward against the sea cliffs, and to draw a high tide into the harbors. Twice each month, at the quarters of the Moon, when the Sun, Moon, and Earth lie at the apexes of a triangular configuration and the pull of the Sun and Moon are opposed, the moderate tidal movements called neap tides occur. Then the difference between high and low water is less than at any other time during the month.

1. The main point of the first paragraph is ...

A. The wave created by ocean currents are very large

B. Despite the strength of the wind, it only moves surface water

D. The tides are the most powerful force to affect the movement of ocean water

2. The word "In reality" in the third sentence of the second paragraph is closest in meaning to

A. Surprisingly

B. Actually

C. Characteristically

D. Similarly

3. According to the passage, the most vital factor in recognizing how much gravitational effect one object in space has on the tides is

A. Size

B. Distance

C. Temperature

D. Density

4. In the ninth sentence of the second paragraph, the word "configuration" is closest in meaning to

A. Unit

B. Center

C. Surface

D. Arrangement

5. Neap tides occur when

A. The sun counteracts the moon's gravitational attraction

B. The moon is full

C. The moon is farthest from the sun
