Almost all our energy comes from oil, coal and natural gas. We call them fossil fuels. The earth’s
fossil fuels are running out. What would happen if there were no oil, coal and gas on earth?
Scientists are trying to find and use other alternative sources of energy. We can use energy
from the sun, the wind and the water.
Solar energy is unlimited. It supplies all the energy used to grow plants, to evaporate water for
rain, and to maintain the temperature of the planet. All are necessary for human life. If we’re able to
collect solar energy, we’ll be sure to make good use of this abundant source of power.
Another source of energy from nature is the wind. Wind power is clean and plentiful. Energy
from the wind has been used for centuries to move ships, grind grain, pump water and do other kinds
of work. In more recent time, wind power has been used to generate electricity.
Water can also provide power. For a long time, people have used water to power machines.
Some early uses of water power were to mill grain, saw wood and power machinery for the textile
industry. Today water power is mostly used to generate electricity.
11. We are asking the question “What would happen if there were no oil, coal and gas on earth?” because ___.
A. we are now depending so much on fossil fuels.
B. we are looking forward to seeing great changes.

II. Choose from sentences A-G the one which fits each gap 1-5. There is one extra sentence you do not need to use. (1,0 p)

Every body has heard about the Internet, but do you know what an “internet” is? (0)___B____

In fact, intranets make use of the same software programs as the internet to connect computers and people. (1)__________.

If your intranet is working properly, it can link together huge amounts of information which is stored in different places in the company. ____________.

A company intranet can, of course, be used for unimportant information like office memos and canteen menus. (3)___________.

The intranet is a great idea, but the systemonly works if everyone on the intranet is willing to share their information with other people. (4))___________.

Another problem which often occurs is that top managers like to use the intranet to “communicate down” rather than to “communicate across”. (5)__________.

Unfortunately, many departments don’t want to share specialist knowlegde with others. It is a computer network that is private to a company, university, etc, but it is connected to and uses the same software as the Internet. In this way, people can get the information they need, regardless of where it comes from. Most employers prefer to communicate by telephone or in writing. But an intranet should provide important information which people need to make decisions about new products, costing and so on. This means that you do not have to buy a lot of additional programs to set up an intranet service. That is, they use the intranet to give orders, not to exchange information between themselves and others working in the same organization.

Are you looking for a cheap. clean, effective source of power that doesn't cause pollution or waste natural resources? Look no further than solar energy from the sun. At present, most of our electricity comes from the use of coal, gas, oil, or nuclear power. This power could be provided by the sun. One percent of the solar energy that reaches the Earth is enough to provide power for the total pollution. Many countries are already using solar energy. Solar panels are placed on the roof of a house and the Sun's energy is used o heat water. The energy can be stored for a number of days, so on cloudy days you can use solar energy. Sweden has an advanced solar energy program. There, all buildings will be heated by solar energy and cars will use solar energy instead of gas by the year 2015.

True or False sentence:

1....................Solar energy can be cheap and clean.

2....................Most of our electricity now comes from nuclear power.

3....................the solar energy that gets to the Earth cannot provide enough power for the world's population.

4....................Solar energy can be used on cloudy days.

5....................All buildings in Sweden will be heated by solar energy in 2050.

Paper is named for papyrus, a reed like plant used by ancient Egyptians as writing material more than 5000 years ago. The Chinese invented the paper that we use 2000 years ago.

A piece of paper is really made up of tiny fibers, unlike a piece of material. The fibers used in paper, however, are plant fibers, and there are millions of them in one sheet. In addition to the plant fiber, dyes and additives such as resin may be used. Dyes can make the paper different colors; resin may add weight and texture.

Where do these fibers come from ? The majority of paper is made from the plant fiber that comes from trees. Millions are cut down, but new trees are planted in their place. Paper may be also made from things like old rags or pieces of cloth. Wastepaper, paper that has been made and used, can be turned into recycled paper. This recycling process saves forest, energy and reduces air and water pollution.

1. According to the passage, the paper that we use was first invented by

A. the Chinese B. the Egyptians C. ancient cultures D. foresters

In Britain, natural gas is the most popular fuel for heating homes, and for cooking. It is piped all over the country from the gas fields below the North sea. Natural gas is used chiefly as a direct source of energy, although it is also used in the chemical industry. At the moment, the supply is plentiful, but it will be running short by the end of the century, and it will run out during the 21st century unless new supplies are found.

In Britain, natural gas is the most popular fuel for heating homes, and for cooking. It is piped all over the country from the gas fields below the North sea. Natural gas is used chiefly as a direct source of energy, although it is also used in the chemical industry. At the moment, the supply is plentiful, but it will be running short by the end of the century, and it will run out during the 21st century unless new supplies are found. We could do without natural gas, as coal gas can be used as a substitute, and there should be enough coal to last for several centuries. However, it is a form of energy which is not only cheap, but also highly efficient.

Questions

1. Where does natural gas come from?

2. When will it run out?

3. Is it efficient?

4. What can be used as a substitute for natural gas?

SECTION III: READING (5.0 points)
Part 1: Read the following passage and choose the correct answer to each of the following
questions. Write your answer (A, B, C, or D) in the numbered boxes.
Since ancient times, one of the most common materials people have utilized to make things
with is wood. Wood is used to make houses, buildings, and other structures. People also
make a large number of smaller objects with it.
The desire to make finished products more beautiful appears to be ingrained in huma n
nature. On account of this fact, for thousands of years, people have carved and shaped
wooden objects to make them more appealing to the eye. Humans have additionally tended
to create both religious and ceremonial objects from wood. In fact, all around the world,
countless cultures have made use of ceremonial wood carvings. These objects often reflect
the spirit of the people who made them, and each of them tends to hold a special
significance as well.
One of the most common types of wood carvings is the mask. People in many cultures in
Asia, Africa, and North America have made ceremonial wooden masks. In Africa, for
instance, large numbers of tribes use wooden masks for vari ous spiritual rituals. These
masks are often in the form of animals that are sacred to the tribes. In other cases, the masks
have human forms. The faces, however, may not be exactly humanlike. For instance, the
faces can be distorted, having wider, longer, smaller, or larger features than normal. The
masks may be carved to give them ugly or frightening appearances as well. And, on other
occasions, the masks are made to look as beautiful as possible.
While masks tend to be fairly small, other wood carvings can be enormous. Among the
largest of all ceremonial wood carvings is the totem p ole. Totem poles have been built by
several Native American tribes that reside in the northwestern part of North America. They
are normally made to represent families, or they may honor significant historical events.
Some even tell stories. A typical totem pole has several individual carvings on it. Each
carving represents a different part of the family history, event, or story. Most totem poles
have human or animal faces, as well as other figures, carved in them. They are so large that
they are made from e ntire trees. Once the trees are cut down, master craftsmen work on
them. When completed, they may or may not be painted. Then, the totem poles are
positioned in places of honor and placed upright.
