Read the passage and check (ü) whether the following statements are true (T) or false (F).

Energy makes change; it does things for us. It moves cars along the road and boats over the water. It bakes a cake in the oven and keeps ice frozen in the freezer. It plays our favourite songs on the radio and lights our homes. Energy makes our bodies grow and allows our minds to think. Scientists define energy as the ability to do work. People have learned how to change energy from one from one form to another so that we can do work more easily and live more comfortably.

All forms of energy are stored in different ways, in the energy sources that we use every day. These sources are divided into two groups – renewable and nonrenewable. Renewable energy source is an energy source that can be replenished in a short period of time. Nonrenewable energy source is an energy source that we are using up and cannot recreate in a short period of time.

Renewable energy sources include solar energy, which comes from the Sun and can be turned into electricity and heat. Wind, geothermal energy from inside the Earth, biomass from plants, and hydropower and ocean energy from water are also renewable energy sources.

However, we get most of our energy from nonrenewable energy sources, which include the fossil fuels – oil, natural gas, and coal. They’re called fossil fuels because they were formed over millions and millions of years by the action of heat from the Earth’s core and pressure from rock and soil on the remains of dead plants and animals. Another nonrenewable energy source is the element uranium, whose atoms we split (through a process called nuclear fission) to create heat and ultimately electricity.

Question: Most of our energy we use every day comes from renewable energy sources.

A. True

B. False

Read the following two passages and choose the correct answer to each question.

Every year in late December, a southward-moving current warms the water along the Pacific coast of Peru. Because the warm current arrives around Christmas, the Peruvians named it El Nino, "boychild". Until the mid 1970s, El Nino was an unrecognised local phenomenon, until scientists began to realise that El Nino, later named EI Nino Southern Oscillation (ENSO), is part of a huge ocean and atmosphere system that is felt as far away as Australia and Indonesia.

Every few years the El Nino current is warmer than normal, causing greater ocean warming and consequently changes in the normal patterns of sea and surface temperatures. The resulting changes in atmospheric pressure affect trade wind speeds and the location of the largest thunderstorms, thus affecting weather patterns around the world. The shift in location of the Pacific's largest thunderstorms, which usually occur from the Western Pacific to the Central Pacific, changes global weather patterns because the thunderstorms pump air into the atmosphere in different places than normal. The result is a shift in the location of high- and low-pressure areas, wind patterns, and the paths followed by storms.

From 1982 to 1983 the El Nino condition caused greater than average precipitation along the US West Coast and sent five hurricanes to French Pollynesia, which normally goes years without hurricanes. That same year, El Nino was linked to floods in Louisiana, Florida, Cuba, Ecuador, Peru, and Bolivia, and to droughts in Hawaii, Mexico, Southern Africa, the Philippines, Indonesia and Australia.

In response to the 1982-83 global weather disruption, the World Meteorological Organization initiated the Tropical Ocean and Global Atmosphere (TOGA) program. The goal of the 10-year program is to gain a better understanding of El Nino so scientists can forecast future El Nino episodes and their likely results.

1. Which of the following could be the title of the passage?

A. A Natural Phenomenon

B.An Ocean and Atmosphere System

C.A Kind of "Boychild"

D. The Forecast of the Future

2. The highlighted word "it" in the passage refers to __________.

A. December

B. the warm current

C. Christmas

D. the coast of Peru

3. It can be inferred from the passage that before the mid 1970s the scientists __________.

A.had already realized El Nino

B.knew nothing about El Nino

C. devised the name El Nino

D. felt El Nino in Australia and Indonesia

4. According to the passage, El Nino can affect __________.

A. wind speed

B. world trade

C. the atmosphere

D. the oceans

5. With which of following does the word “initiated” in the passage could best be replaced?

A. produced

Read the following passage, and mark the letter (A, B, C or D) on your answer sheet to indicate the correct answer to each question.

What geologists call the Basin and Range Province in the United States roughly coincides in its northern portions with the geographic province known as the Great Basin. The Great Basin is hemmed in west by the Sierra Nevada and on the east Line by the Rocky Mountains; it has no outlet to the sea. The prevailing winds in the Great Basin are from the west. Warm, moist air from the Pacific Ocean is forced upward as it crosses the Sierra Nevada. At the higher altitudes it cools and the moisture it carries is precipitated as rain or snow on the western slopes of the mountains. That which reaches the Basin is air wrung dry of moisture. What little water falls there as rain or snow, mostly in the winter months, evaporates on the broad, flat desert floors. It is, therefore, an environment in which organisms battle for survival. Along the rare watercourses, cottonwoods and willows eke out a sparse existence. In the upland ranges, pinion pines and junipers struggle to hold their own.

But the Great Basin has not always been so arid. Many of its dry, closed depressions were once filled with water. Owens Valley, Panamint Valley, and Death Valley were once a string of interconnected lakes .The two largest of the ancient lakes of the Great Basin were Lake Lahontan and Lake Bonneville. The Great Salt Lake is all that remains of the latter, and Pyramid Lake is one of the last briny remnants of the former. There seem to have been several periods within the last tens of thousands of years when water accumulated in these basins. The rise and fall of the lakes were undoubtedly linked to the advances and retreats of the great ice sheets that covered much of the northern part of the North American continent during those times. Climatic changes during the Ice Ages sometimes brought cooler, wetter weather to mid latitude deserts worldwide, including those of the Great Basin. The broken valleys of the Great Basin provided ready receptacles for this moisture.

 to the passage, what does the Great Basin lack?

A. Snow 

B. Dry air 

C. Winds from the west 

D. Access to the ocean
