III. Read the following passage and mark the letter A, B, C or D on your answer sheet to indicate the correct answer to each of the questions.
            Lake Victoria is the largest lake in Asia. It is one of the sources for the Nile River and provides a source of water, food and power for several African countries.
            Unfortunately, Lake Victoria has a problem. It is shrinking. There are several power stations at Lake Victoria in Uganda. These are on the Nile River, and in addition to generating power, they keep the water levels of Lake Victoria steady. For the past fourty years, that level has been 11.9 meters. Over the last several years, the water level has dropped by about 2.5 meters. There appear to be several reasons for this drop.
            One commonly blamed reason is drought. Drought has been very bad in the area since 2000. Lake Victoria gets all of its water from rains, so the drought means less water in the lake.
            However, some environmentalists believe that the real problem is the power plants on Lake Victoria. Uganda relies on those power plants for most of its power, and they made the power plants larger in 2000. Many people believe the power plants have been taking too much water off Lake Victoria.
            Whether the low water level is caused by drought or power plants, the result is the same. This is already a poor area of Africa, where many people struggle to survive. People, animals and plants around Lake Victoria will suffer even more from lower water levels on the lake. Many people need this lake for fishing or growing food. Fish need water to live, and animals need it for water. Plants around the lake will die without the water, and then more animals and people will suffer and die.
The word “generating” in the passage refers to ________.
A.enlarging
B.producing
C.needing
D.building

Read the following passage and mark the letter A, B, C or D on your answer sheet to indicate the correct answer to each of the following questions.
            The word robot first appeared in a 1921 stage play by Czech writer Karel Capek. In the play, a man makes a machine that can think, which he calls a robot and which ends up killing its owner. In the 1940s, the American science fiction writer Isaac Asimov wrote a series of stories about robots and invented the term robotics, the science of robots. Meanwhile, in the real world, the first robots were developed by an engineer, Joseph F. Engelberger, and an inventor, George C. Devol. Together they started Unimation, a manufacturing company that produces the first real robot in 1961, called the Unimate. Robots of this type were installed at a General Motors automobile plant and proved to be a success. They worked reliably and saved money for General Motors, so other companies were soon acquiring robots as well.
            These industrial robots were nothing like the terrifying creatures that can often be seen in science fiction films. In fact, these robots looked and behaved nothing like humans. They were simply pieces of computer-controlled machinery, with metal “arms” or “hands”. Since they were made of metal, they could perform certain jobs that were difficult or dangerous for humans, particularly jobs that involve high heat. And since robots were tireless and never got hungry, sleepy, or distracted, they were useful for tasks that would be
tiring or boring for humans. Industrial robots have been improved over the years, and today they are used in many factories around the world. Though the use of robots has meant the loss of some jobs, at the same time other jobs have been created in the design, development, and production of the robots.
