When we hear of dangerous diseases, cancer and heart disease are often what first come

to mind. Recently, a virus called Ebola has reappeared in Guinea, killing 62 people so far. It leads to high fever, bleeding and so on. Ebola can kill 90% of those infected (感染), especially in underdeveloped societies like those in Africa.

Ebola is named after the Ebola River, where it was first discovered in 1976. There are five different types of the Ebola virus, each named after where they first happened: Sudan, Ivory Coast, Reston, Bundibugyo, and Zaire. The deadliest of the five, Zaire, was responsible for the 2012 outbreak, and is believed to be attacking Guinea.

Ebola is naturally found in fruit bats, which pass on the virus to other animals by biting or sucking on their blood. Humans who are suffering from the Ebola infection might have touched the bodily fluids (體液) of the infected animals. Once infected, a human becomes a carrier of the deadly virus.

Since we live in an interconnected world, where the situation in one country can affect us all, the effects of Ebola are huge: damaging trade relations, affecting foreign visitors, and weakening entire countries. Already the Guinea virus is spreading fast with a few cases spotted in Conakry—the capital city of Guinea, far away from the origin of the virus. It is feared that the disease may have already reached neighboring Liberia and Sierra Leone, too.

Unfortunately, there are no disease-specific treatments for Ebola. Healthcare workers only supply the infected people with water to keep them in good condition. Since there have been many cases of nurses catching the disease from patients, they are forced to wear strict protective clothes, and in some cases, not even allowed to get close to the infected. The fact that there is no cure for the Ebola virus is what makes the outbreak a challenging one to control.

1.From the text we know that ________.

A. Ebola is naturally found in fruit

B. Ebola is a highly infectious virus

C. Ebola is a newly discovered disease

D. Ebola is recently controlled in Guinea

2.What is Paragraph 4 mainly about?

C. The treatment for Ebola. D. The influences of Ebola.

3.In Ebola infected areas, healthcare workers _______.

A. face the danger of catching virus

B. take measures to protect the nurses

C. give water and medicine to the patients

D. do whatever they can to save the infected

4.The text probably comes from ________.

The earth is the only planet that scientists think has life. Why does the earth have life while the other planets don’t? For one thing, the earth is just the right temperature. As the third planet from the sun, the earth seems to be just the right distance away. The planets which are closer to the sun are so hot. The farthest planets are cold balls.

When the earth developed—which scientists believe may have happened about 4 billion years ago—many gases covered the earth. The gases caused the earth to be hot. But something wonderful happened. The temperature was just right for thick clouds to form. It rained very hard for a very long time. This gave the earth its oceans. Water made it possible for plants to grow. The plants created oxygen in the atmosphere. Oxygen is the gas that humans and animals breathe.

Only one other planet in the solar system seems to be something like the earth. That planet is Mars(火星). Mars is smaller than the earth, and it is quite a bit cooler. But it is not too cold for humans. On some days, the temperatures are as low as a winter day in the northern United States. If you wore a special spacesuit, you could walk around on Mars. The most difficulty is that you have to bring your own air to breathe, because the air on Mars is too thin to breathe.

Mars has the largest volcano(火山) in the solar system. It is sixteen miles high. The highest volcano on the earth is five miles high. Scientists believe that Mars was once much better than it is now. Does this mean there could have been living things on Mars? Scientists are not sure, but there has been no sign so far.

1.Which of the following is NOT the reason that the earth has life?

A. The earth is just the right temperature.

B. There is oxygen in the atmosphere of the earth.

C. The volcanoes on the earth are lower than those on Mars.

D. The earth seems to be just the right distance away from the sun.

2.The underlined phrase “the third planet” in the first paragraph refers to_______.

A. the Sun B. the Moon

C. the Earth D. the Mars

3.Which of the following about the Mars is NOT true?

A. There is almost no oxygen in the air on Mars.

B. There could have been living things on Mars.

C. Mars has the largest volcano in the solar system.

D. Mars is smaller and quite a bit cooler than the earth.

4.Which is the first trouble for human to live on Mars?

A. The volcanoes. B. The temperature.

C. The air. D. The food.

5.Which of the following is probably the best title for the passage?

A. The Earth B. The Moon

C. Planets in the Solar System D. Mars is Most Like the Earth

Nowadays, there are a lot of films and TV plays that are adapted to popular novels or classical work. Some people think better to read the original, while others are against it.

I think reading the original is too much better than watching its film or TV version because I can experience more after reading the original. Just as a famous saying go, there are a thousand Hamlets in a thousand people’s eye. Different people have different feelings about the book or a certain role. But in the film or TV version, though we can get a main idea more direct, we may miss some wonderful, even important plots. And we are easily misled by the actors or actresses, so they act according to their understand of the book.

In a word, I think reading the original is much better than watching its film or TV version.

Popeye the Sailor first became a popular cartoon in the 1930s.The sailor in that cartoon ate lots of spinach to make him strong. People watched him, and they began to buy and eat a lot more spinach. Popeye helped sell 33 percent more spinach than before! Spinach became a necessary part of many people’s diets. Even some children who hated the taste began to eat the vegetable.

Many people thought that the iron in spinach made Popeye strong, but this is not true. Spinach does not have any more iron than any other green vegetable.

People only thought spinach had a lot of iron because the people who studied the food made a mistake. In the 1890s, a group of people studied what was inside vegetables. This group said that spinach had ten times more iron than it did. The group wrote the number wrong, and everyone accepted it.

Today, we know that the little iron there is in spinach cannot make a difference in how strong a person is. However, spinach does have something else which the body needs—folic acid.

It is interesting to point out that folic acid can help make a person strong. Maybe it was really the folic acid that made Popeye strong all along.

1.A good title for this reading passage is______.

A. Popeye the Sailor B. The Truth About Spinach

C. A Mistake with Numbers D. Folic Acid Makes You Strong

2.Why did many people eat spinach after they saw Popeye the Sailor?

A. They thought spinach made them strong.

B. They thought Popeye was funny.

C. Spinach had a lot of iron.

D. People liked folic acid.

3.A research group told people that spinach______.

A. made Popeye strong

B. was a green vegetable

C. had less iron than other green vegetables

D. had more iron than other green vegetables

4.The reading passage says that perhaps Popeye got his strength from______.

A. iron B. folic acid

C. spinach D. exercise

5.Folic acid is ______.

A. something in food B. a vegetable

C. dangerous D. a certain kind of spinach
