题目
题型：不详难度：来源：
In formal paragraphs you will sometimes see a sentence at the end of the paragraph which summarizes the information that has been presented．This is the concluding sentence．The concluding sentence is similar to the topic sentence．They are both general sentences．The concluding sentence can be written in two ways：
1．State the topic sentence in different words．
2．Summarize the main points in the paragraph．
You can understand concluding sentences with this example．Consider a hamburger that you can buy at a fast—food restaurant．A hamburger has a top bun，meat，cheese，lettuce（生菜），and other elements in the middle of the hamburger，and a bottom bun．Note how the top bun and the bottom bun are very similar．The top bun，in a way，is like a topic sentence，and the bottom bun is like the concluding sentence．Both buns “hold” the meat，onions，and so on．Similarly，the topic sentence and concluding sentence “hold” the supporting sentences in the paragraph．Let’s see how a concluding sentence might look in our sample paragraph about Wheaton：
My hometown is famous for several amazing natural features．First，it is noted for the Wheaton River，which is very wide and beautiful．Also，on the other side of the town is Wheaton Hill，which is unusual because it is very steep．The third amazing feature is the Big Old Tree．This tree stands two hundred feet tall and is probably about six hundred years old．These three landmarks are truly amazing and make my hometown a famous place．
Notice how the concluding sentence，“these three landmarks are truly amazing and make my hometown a famous place”，summarizes the information in the paragraph．Notice also how the concluding sentence is similar to，but not exactly the same as，the topic sentence．
Usually，we begin a concluding sentence with “in conclusion’’ or “in summary”．Remember，not all paragraphs contain concluding sentences，especially if the paragraph is very short．However，if your paragraph is very long，it is a good idea to use a concluding sentence．
65．What does the author mainly intend to tell us in this passage？
A．How to write a concluding sentence．
B．What the top bun and the bottom bun are like．
C．Why his hometown is a famous place．
D．To use a concluding sentence in our writing．
66．Why does the author write about a hamburger？
A．Because he can buy a hamburger at a fast—food restaurant．
B．Because a hamburger has a top bun and a bottom bun．
C．Because the top bun and the bottom bun are very similar．
D．Because he wants to explain his main idea in another way．
67．The underlined word “noted” probably means“ ”
A．written down B．famous C．noticed D．recorded
68．Which of the following statements is TRUE about the passage？
A．A sentence at the end of a paragraph is the concluding sentence．
B．All paragraphs contain concluding sentence．
C．It is a good idea to use a concluding sentence in a long paragraph．
D．The concluding sentence is the same as the to pic sentence．
69．The underlined phrase “These three landmarks” here refers to ．
A．the Wheaton River，Wheaton Hill and my hometown
B．natural features，the Wheaton River and the Wheaton Hill
C．the Wheaton River，Wheaton Hill and the Big Old Tree
D．my hometown，Wheaton Hill and the Big Old Tree

举一反三
Scientists have developed a water treatment system that they say is a powerful but simple way to save lives. Four grams of chemicals can treat ten liters of dirty water for a low cost, about ten cents.
Experts say infections from dirty water kill several thousand children in developing countries every day. The Procter and Gamble company has been developing the "PUR Purifier of Water" system since 1995. The company has been working with the United States Centers for Disease control and Prevention(C.D.C.).
C.D.C. researchers tested it in Guatemala, Pakistan and Kenya. Procter and Gamble researcher Greg Allgood says cases of diarrhea(腹泻) in those studies fell by about 50 percent. Researchers from Johns Hopkins University in Maryland tested the system at a refugee camp in Liberia. Mr. Allgood says that study found a reduction of more than 90 percent. Use of the system is being expanded worldwide.
The treatment contains bleach(漂白剂) to kill disease-causing organisms. It also contains something that dirt and other particles stick to. Mr. Allgood says the chemicals can remove lead and other dangerous metals and even agricultural poisons like D.D.T.
Mr. Allgood heads the Children"s Safe Drinking Water program at Procter and Gamble. He says about forty million packets of the treatment have been given to countries for free. They have been used in emergencies and in areas with limited supplies of clean water.
Clean water is a limited resource in many parts of the world. Delegates from about 130 nations attended the Fourth World Water Forum last month in Mexico City. Scientists, policy experts and others discussed ways to provide clean water to the world’s poor. Organizers say more than twenty percent of the world population lacks clean drinking water. The final declaration did not go so far as to declare water a human right. But it did say that governments, not private companies, must take the lead in improving the public’s ability to have clean water.

A. It is effective but very expensive.
B. It was tested in Guatemala, Pakistan and Kenya.
C. It is being expanded worldwide.
D. It can remove dangerous metals in the water.
49. Which of the following shows that the shortage of clean water is a serious problem?
A. Forty million packets of the treatment have been given to countries for free.
B. Delegates from about 130 nations attended the Fourth World Water Forum.

Alzheimer"s disease affects millions of people around the world. American researchers say the disease will affect more than one hundred million people worldwide by the year twenty fifty. That would be four times the current number. Researchers and doctors have been studying Alzheimer"s patients for a century. Yet the cause and cure for the mental sickness are still unknown. However, some researchers have made important steps towards understanding it.
Several early signs of the disease involve memory and thought processes. At first, patients have trouble remembering little things. Later, they have trouble remembering more important things, such as the names of their children.
There are also some physical tests that might show who is at risk of developing Alzheimer"s disease. The tests look for proteins in brain and spinal cord fluid. The proteins appear to be found only in people with the disease. The protein tests correctly identify the presence of the disease in about ninety percent of patients.
Now, a much simpler physical test to predict Alzheimer"s risk has been developed. Researchers found that trouble with the sense of smell can be one of the first signs of Alzheimer"s. Using this information, they developed a test in which people were asked to identify twelve familiar smells. These smells included cinnamon, black pepper, chocolate, paint thinner, and smoke.
The study continued for five years. During this period, the same people were asked to take several tests measuring their memory and thought abilities. Fifty percent of those who could not identify at least four of the smells in the first test had trouble with their memory and thinking in the next five years.
Another study has shown a possible way to reduce a person"s chances of developing Alzheimer"s disease in old age. Researchers in Chicago found that people who use their brains more often are less likely to develop Alzheimer"s disease. Those who read a newspaper, or play chess or word games are about three times less likely to develop the condition.
Researchers say they still do not know what causes Alzheimer"s disease. But they say these findings might help prevent the disease in the future.
41. What’s the main idea of the passage?
A. Some early signs of the Alzheimer"s disease.
B. Some physical tests about Alzheimer"s disease.
C. The research about Alzheimer"s disease.
D. The patients of Alzheimer"s disease.
42. What’s the current number of Alzheimer’s patients?
A. 100 million B. 25 million C. 400 million D. 2050 million
43. What is not the early signs of the Alzheimer"s disease according to the passage?
A. Poor memory B. Proteins exist in the brain.
C. Trouble with the sense of smell. D. Less use of the brain.
44. What does the underlined word “it” in paragraph 1 refer to?
A. Alzheimer"s disease. B. Alzheimer"s patients.
C. The cause and cure. D. The research.
45. According to the passage, we can learn that _______.
A. there are no proteins in the brains of the people with no Alzheimer"s disease
B. the people who often use their brains will not get Alzheimer"s disease
C. researchers and doctors have found ways to cure Alzheimer"s disease
D. the people who have the trouble with the sense of smell will certainly suffer from Alzheimer"s disease
1. Most historians hold that the Chinese invented fireworks in the 9th century when they
discovered how to make gunpowder. Story has it that a Chinese cook accidentally mixed together what were then considered common kitchen items and noticed they burnt. When put tightly in a bamboo tube and lit, it blew up.
2. In May of 1886, a law led John Pemberton, a pharmacist（药剂师）, to rewrite the formula(配方) for "Pemberton’s French Wine Coca,” his popular headache treatment. Containing sugar instead of wine as a sweetener, the outcome became something for Coke, which was later mixed with carbonated water. His bookkeeper suggested the name Coca-Cola because he thought the two C’s would look good together, which is how what we call Coca-Cola, a world –wide drink came into being.
3. During World War II, scientists at the University of Birmingham invented the magnetron—an important heat-producing part of the microwave oven(微波炉). While working for Raytheon Corporation after the war, the American engineer Percy Spencer was testing the magnetron when a chocolate bar in his pocket melted. He went on to test other foods including popcorn kernels, and found it to be a much more efficient way to cook. In 1947 Raytheon came out with the first restaurant microwave oven, which was six feet tall and weighed 750 lbs.

Show Your Bones is the newest album from a musical group with an unusual name, the Yeah Yeah Yeahs. The energetic music made by these rock musicians is becoming very popular in America.
A singer, a guitar player and a drummer make up the Yeah Yeah Yeahs. Their rock sound is creative, unusual, and full of personality. Their music is considered an example of “indie”(short for independent) rock. Indie musicians like to protect their independence and artistic freedom. One way to do this is to avoid using major record companies. The lead singer Karen O is known for wearing wild clothing and having wild hairstyles while performing. Sometimes she even pours beer over herself and the audience. Imagine Karen O dancing around on stage as you listen to her sing the song, Phenomena.
The words in the songs on Show Your Bones are poetic and also a little strange. It is not always clear what the songs mean. In the song called The Sweets, Karen O describes colors and the motion of water. Also, she wonders about meeting someone again.
The Yeah Yeah Yeahs started playing music together in New York City.
Now Karen O has moved to Los Angeles, California. She says that she likes flying between the two cities and the band is now “bi-coastal”. Karen O also said that this album was the most difficult to make. The band was trying to find a different sound from their earlier albums. Their work seems to have been worth the effort. Critics say Show Your Bones might be one of the best albums of the year.
