Read the following passage and mark the letter on your answer sheet to indicate the correct word for each blank.

We are descendents of the ice age. Periods of glaciation have spanned the whole of human existence for the past 2 million years. The rapid melting of the continental glaciers at the end of the last ice age spurred one of the most dramatic climate changes in the history of the planet. During this interglacial time, people were caught up in a cataclysm of human accomplishment, including the development of agriculture and animal husbandry. Over the past few thousand years, the Earth’s climate has been extraordinarily beneficial, and humans have prospered exceedingly well under a benign atmosphere.

Ice ages have dramatically affected life on Earth almost from the very beginning. It is even possible that life itself significantly changed the climate. All living organisms pull carbon dioxide out of the atmosphere and eventually store it in sedimentary rocks within the Earth’s crust. If too much carbon dioxide is lost, too much heat escapes out into the atmosphere. This can cause the Earth to cool enough for glacial ice to spread across the land.

In general the reduction of the level of carbon dioxide in the atmosphere has been equalized by the input of carbon dioxide from such events as volcanic eruptions. Man, however, is upsetting the equation by burning fossil fuels and destroying tropical rain forests, both of which release stored carbon dioxide. This energizes the greenhouse effect and causes the Earth to warm. If the warming is significant enough, the polar ice caps eventually melt.

The polar ice caps drive the atmospheric and oceanic circulation systems. Should the ice caps melt, warm tropical waters could circle the globe and make this a very warm, inhospitable planet.

Over the past century, the global sea level has apparently risen upwards of 6 inches, mainly because of the melting of glacial ice. If present warming trends continue, the seas could rise as much as 6 feet by the next century. This could flood coastal cities and fertile river deltas, where half the human population lives. Delicate wetlands, where many marine species breed, also would be reclaimed by the sea. In addition, more frequent and severe storms would batter coastal areas, adding to the disaster of the higher seas.

The continued melting of the great ice sheets in polar regions could cause massive amounts of ice to crash into the ocean. This would further raise the sea level and release more ice, which could more than double the area of sea ice and increase correspondingly the amount of sunlight reflected back into space. The cycle would then be complete as this could cause global temperatures to drop enough to initiate another ice age.

 Which of the following does the author NOT mention as a consequence of a large rise in global sea level?

 

 

A. The destruction of wetlands

B. The flooding of cities 

C. A more diverse marine population

D. Severe storms

Schooling is compulsory for all English children from the age of 5 to 16. The academic year in England runs from September to July and is divided into three terms. Autumn Term is from the beginning of September to mid – December. Spring Term is from the beginning of January to mid- March and Summer Term from early April to mid – July. Each term is separated by a one-week break called half terms, usually at the end of October, mid- February and the end of May.

There are two parallel school systems in England. The first is the state school system, which is free for all students and paid for by the state. The second category is the “independent” or “public school system, which is fee-paying. The state school system, which educates 93% of the pupils in England, can be divided into two levels of education: primary education and secondary education.

The National Curriculum is set by the government and must be followed in all state schools. It is made up of the following subjects : English, Design and Technology , Geography, Maths, Information Technology , Music , Science , Arts , Physical Education , History and a Modern Foreign Language. English, Maths and Science are core subjects, which are compulsory in the national examination at certain stages of the school education system.

A. When they are from 5 to 16 years old.                    B. When they are under 5 years old.

C. When they are 16 years old.                                    D. When they are 5 years old.

Question 9:  When do students in England take their half terms?

A. At the end of the school year B. At the end of each term                   

C. In the middle of each term                          D. At the beginning of each term                

Question 10:  The phrase is made up of in the passage means………………

A. exclude                       B. be compulsory

C. include                           D. produce

ALTERNATIVE ENERGY SOURCES

A number of different energy sources are used every day. Burning of fossil fuel is a main energy source. Sources other than this fossil fuel are known as alternative energy sources and there are several of them being used every day.

First of all is water. Water energy can be harnessed to perform work by using waterwheels. In a hydroelectric plant the running or falling water spins a generator to create electricity.

Not only does water spin a wheel, but wind can do so as well. Windmills work in the same manner as a waterwheel. Windmills are used as wind turbines that can generate electricity.

The internal heat of the earth is another energy source. It is called geothermal energy. Geothermal energy can be used to heat homes and produce electricity.

Solar energy is often thought to be sunlight. Sunlight is full of energy. People are finding new ways to harness the power of sunlight. One major way is to trap or concentrate sunlight with the use of solar panels. This trapped sunlight can be used to heat homes and water. Also solar cells are devices that convert sunlight into electric energy.

Question 28. Which of the following is a device that converts sunlight into electric energy?

A. Solar cells B. Solar panels C. Converters D. Hydro panels

Question 29. Which of the following is a tool used to trap or concentrate sunlight to be used for energy?

A. Solar cells B. Solar panels C. Solar devices D. Solar censors

Question 30. Which of the following is NOT an alternative source of energy?

A. Water B. Wind C. Sun D. Plants

Question 31. Sources of energy other than fossil fuel are called which of the following?

A. Alternative sources of energy B. Geothermal energy

C. Solar energy D. Water energy

Question 32. Water energy can be harnessed by using which of the following tools?

A. Windmills B. Waterwheels

C. Aqua cells D. Hydroelectric wheels

Delicate wetlands, where many marine species breed, also would be reclaimed by the sea. In addition, more frequent and severe storms would batter coastal areas, adding to the disaster of the higher seas.

The continued melting of the great ice sheets in polar regions could cause massive amounts of ice to crash into the ocean. This would further raise the sea level and release more ice, which could more than double the area of sea ice and increase correspondingly the amount of sunlight reflected back into space. The cycle would then be complete as this could cause global temperatures to drop enough to initiate another ice age.
