VI. Read the passage, and choose the correct answer A, B, C or D for each question.

Saving the Environment: One Home at a Time

Pollution can be seen not only throughout the world, but also in our own homes. It comes from household chemicals, the amount of water people use and the waste people produce and throw away. What can be done to stop this pollution? Surprisingly, a person can help save the environment by doing simple things.

First, we need to recycle, which allows products to be used over and over again. Recycling can also reduce the number of trees cut down to produce paper products. It takes very little effort. It is not hard to place plastic and glass bottles, aluminum cans and paper in a bin. Anyone can do it.

Second, we need to watch the amount of water used at home. It can be conserved by taking short showers instead of baths, repairing leaky faucets, using the dishwasher or washing machine only when fully loaded, or simply turning the faucet off while brushing your teeth.

Third, we need to reduce waste. We need to recycle whenever possible, but should also try to use this waste effectively. For example, grass clippings and food scraps can be made into compost for plants. The average person produces 4.3 pounds of waste every day, but we can reduce that amount by recycling and reusing.

If we do our part in our own homes, we can help keep the planet from becoming more polluted.

1. Pollution is caused from the following sources except .

A. water in rivers B. water from households

C. wastes D. house chemicals

2. Recycling can help us .

A. never cut down trees B. produce more paper products

C. place garbage bins easily D. use products again and again

3. In order to save water, we can do all of the following things except .

A. fully use the washing machine

B. repair leaky faucets

C. take short showers instead of baths

D. turn the faucet off while brushing your teeth

4. Recycling helps to reduce waste because .

A. plants need to develop

B. waste can be recycled and reused

C. a person can do it in his home

D. an average man produces compost for plants

5. The word “It” in paragraph 2 refers to .

A. cutting down B. the number

C. recycling D. effort

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.

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.

V. Read the following passage and then answer the questions below it.

Air pollution is a cause of ill-health in human beings. In a lot of countries there are laws limiting the amount of smoke which factories can produce. Although there isn’t enough information on the effects of smoke in the atmosphere, doctors have proved that air pollution causes lung diseases.

The gases from the exhausts of cars have also increased air pollution in most cities. The lead in petrol produces a poisonous gas which often collects in busy streets surrounded by high buildings. Children who live in areas where there is a lot of lead in the atmosphere cannot think as quickly as other children and they are clumsy when they use their hands.

There are other long-term effects of pollution. If the gases in the atmosphere continue to increase, the earth’s climate may become warmer. A lot of the ice near the Poles may melt and may cause serious floods.

1. What can make people sick?

=> Air pollution can made people sick_____

2. Where does smoke come from?

=> _Smoke comes from the exhausts of cars

Air pollution threatens the health of the people who live in cities. City wastes cause water pollution when they are poured into the waterways. These wastes kill fish and make some areas unfit for swimming. In addition, many large cities have difficulties in disposing of their garbage. The amount of garbage grows each year, but places to put it are quickly filling up. Citizens, governments, industries, scientists, and business people must work together in different ways to gradually reduce pollution. For example, most cities have introduced recycling programmes.

Read the following passage and choose the correct answer to each questions.

Your mind's ability to bring back experiences you have had is your memory. There are two kind of remembering, recall and recognition. For instance, you may not be able to recall the poem you read yesterday in class, but if you see it again, you will know it instantly because you recognise it.

Some few people have "total recall", often spoken of as photographic memory. A person with total recall can recite a whole page of a book he has read only once, or play a musical composition after hearing it once. This is very unusual, however, and most people have difficulty in remembering even the names they heard the day before. This is not because most people lack the ability to remember, but because they had not paid much attention to what they heard. They felt no personal reasons to remember. Having a personal reason for remembering is one of the most important factors in a good memory.

When you have a strong reason for remembering, concentrate as you read or listen, and try to connect the new information to things you already know. A detail is easy to remember when it fits into a whole that make sense. If you understand the entire history lesson before you try to remember any particular dates, your memory may surprise you.

A. to ask other people to repeat something again and again

D. to learn everything you read or hear by heart

2. This article as a whole tells us about __________.

A. people who can remember whole pages

B. people who can’t remember names

D. recognition as one way to remember things

3. A person with photographic memory __________.

A. can only remember things if he looks at a photograph

B. can remember every detail of what he sees or hears

C. can be found in mental hospitals

D. brings his camera everywhere he goes

A. Most people lack the ability to remember.

B. Recognition and recall are the two kinds of memory.

C. Your memory is your ability to bring back experiences you had.

D. A person can remember things better if he has a strong reason for doing it.

5. While not directly stated, it may inferred from the article that __________.

B. recall and recognition are the same

C. if one tries hard enough, he can remember as well as another

D. wanting to do a thing is very important to being able to do it
