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

D. The Forecast of the Future

A. December

B. the warm current

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

A hurricane is a huge storm that forms over warm ocean water. Bands of thunderstorms form and swirl around and around because the rotation of the earth. As more and more thunderstorms form, the hurricane gets bigger and bigger. A hurricane is one of the world's worst storms because it can last for days or weeks.

Hurricanes can also be very large. They may cover hundreds of miles and affect large areas of land. For a storm to be classified as a hurricane, wind speeds within the storm have to reach at least 74 per hour. But hurricane winds can reach speeds of over 155 miles per hour! A large amount of destruction may occur with winds that strong. Roofs may be torn off homes. Buildings may be flattened. Trees topple over. Hurricanes are deadly, but not just because of their winds. They can also produce very heavy rains and huge waves that slam into the coastline. Hurricanes are very common along the east coast of the United States. Here, wind, waves, and rain do the most damage.

Luckily, meteorologists (people who study weather) can forecast hurricanes days in advance by using radar technology. Radar is a little bit like a moving picture. It shows how big storms are and which way they are moving. Radar images people time to prepare for a coming storm. If the storm is very strong, home and business owners will put up plywood to protect their glass windows and doors. People who live along the coast will evacuate. They'll go to a hurricane shelter or stay with friends and relatives who live in safer places farther inland. Many lives are saved every year by people who take the necessary precautions.

Question28. What is a hurricane?

A. a tidal wave B. a huge storm C. a thunderstorm D. a tsunami

Question 29. What makes a hurricane?

A. thunderstorms B. strong winds C. seawater D. the earth rotation

Question 30. What of the following is not correct?

A. A hurricane is very dangerous because it lasts for days and weeks.

B. The hurricane wind speeds per hour can be nearly twice as fast as the wind speeds.

C. A hurricane can reach speeds of at least 74 km per hour.

D. Hurricanes often appear along the east coast of the United States.

Question 31. Who is meteorologist?

A. People study weather.

B. People do businesses in the meteorological field.

C. People live along the coast.

D. People are evacuated from the regions affected by hurricanes.

Question 32. What is radar used for?

A. making moving pictures

B. showing the size of hurricanes and their movements

C. giving people time to prepare for a coming storm

D. All above

Until the 1600s, English was, for the most part, spoken only in England and had not extended even as far as Wales, Scotland, or Ireland. However, during the course of the next two centuries, English began to spread around the globe as a result of exploration, trade (including slave trade), colonization, and missionary work. Thus, small enclaves of English speakers became established and grew in various parts of the world. As these communities proliferated, English gradually became the primary language of international business, banking, and diplomacy.
Currently, about 80 percent of the information stored on computer systems worldwide is in English. Two-thirds of the world's science writing is in English, and English is the main language of technology, advertising, media, international airports, and air traffic controllers. Today there are more than 700 million English users in the world, and over half of these are non-native speakers, constituting the largest number of non-native users than any other language in the world. 1.

Volcanoes have been erupting on the earth for millions of years. More than five hundred of them still erupt today. These are called active volcanoes. Volcanoes are located in belts or chains. They are found where the earth’s crust is weak. The weak spots let the hot rock escape when the volcano erupts.

Many volcano belts are mountain ranges along the edges of continents. One belt runs along the western coast of South America up through the western part of the United States. Other volcanoes are found in ocean basins.

About three-fifths of all active volcanoes in the world are in the Pacific Ocean. Many of these volcanoes erupt under the water. The Hawaiian Islands were built by volcanoes that began erupting under water and finally reached the surface of the ocean.

1. The passage says that about five hundred volcanoes_____.

A. will erupt this year B. are still active C. are located under water D. have been discovered

2. Most of the active volcanoes are located in_____.

A. the Pacific Ocean B. South America C. the Atlantic Ocean D. the western United States

3. Which of the following is NOT true?

A. Volcanoes are found in belts or chains. B. The earth’s crust is weak along mountain ranges. C. Hot rock escapes during volcano eruption. D. Volcanoes can be found in the ocean basins.
