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?

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______.

C. spinach D. exercise

5.Folic acid is ______.

A. something in food B. a vegetable

C. dangerous D. a certain kind of spinach

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?

A. The causes of Ebola. B. The origin of Ebola.

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 ________.

A. an English newspaper B. a tourist guide

C. a safety brochure D. a medical report

For many parents, raising a teenager is like fighting a long war, but years go by without any clear winner. Like a border conflict between neighboring countries, the parent-teen war is about boundaries: Where is the line between what I control and what you do?

Both sides want peace, but neither feels it has any power to stop the conflict. In part, this is because neither is willing to admit any responsibility for starting it. From the parents’ point of view, the only cause of their fight is their adolescents’ complete unreasonableness. And of course, the teens see it in exactly the same way, except oppositely. Both feel trapped.

In this article, I’ll describe three no-win situations that commonly arise between teens and parents and then suggest some ways out of the trap. The first no-win situation is quarrels over unimportant things. Examples include the color of the teen’s hair, the cleanliness of the bedroom, the preferred style of clothing, the child’s failure to eat a good breakfast before school, or his tendency to sleep until noon on the weekends. Second, blaming. The goal of a blaming battle is to make the other admit that his bad attitude is the reason why everything goes wrong. Third, needing to be right. It doesn’t matter what the topic is ---politics, the laws of physics, or the proper way to break an egg---the point of these arguments is to prove that you are right and the other person is wrong, for both wish to be considered an authority---someone who actually knows something---and therefore to command respect. Unfortunately, as long as parents and teens continue to assume that they know more than the other, they’ll continue to fight these battles forever and never make any real progress.

1.Why does the author compare the parent-teen war to a border conflict?

A. both can continue for generations.

B. Both are about where to draw the line.

C. Neither has any clear winner.

D. Neither can be put to an end.

2.What does the underlined part in Paragraph 2 mean?

A. The teens blame their parents for starting the conflict.

B. The teens agree with their parents on the cause of the conflict.

C. The teens accuse their parents of misleading them.

D. The teens tend to have a full understanding of their parents.

3.Parents and teens want to be right because they want to ________.

A. give orders to the other

B. know more than the other

C. gain respect from the other

D. get the other to behave properly

4.What will the author most probably discuss in the paragraph that follows?

A. Causes for the parent –teen conflicts.

B. Examples of the parent –teen war.

C. Solutions for the parent –teen problems.

D. Future of the parent-teen relationship.

A recent study, while showing a generally positive attitude toward science, also suggests a widespread worry that it may be "running out of control". This idea is dangerous.

Science can be a force for evil as well as for good. Its applications can be channeled either way, depending on our decisions. The decisions we make, personally or collectively, will determine the outcomes of science. But here is a real danger. Science is advancing so fast and is so strongly influenced by businesses that we are likely to believe whatever decisions we come to will make little difference. And, rather than fighting for the best possible policies, we may step back and do nothing.

Some people go even further. They say that despite the moral and legal objections, whatever is scientifically possible will be done-somewhere , sometime. They believe that science will get out of control in the end. This belief is dangerous too, because it fuels a sense of hopelessness and discourages then from making efforts to build a safer world.

In our interconnected world, the lack of agreement in and out of the world of science can lead to the failure to control the use of science. Without a common understanding, the challenges of "controlling" science in this century will be really tough. Take human cloning for example. Despite the general agreement among scientists on its possible huge impact on traditional moral values, some countries still go ahead with the research and development of its related techniques. The outcomes are hard to predict.

Therefore, discussions on how science is applied should be extended far beyond scientific societies. Only through the untied efforts of people with hope, can we be fully safe against the misuse of science and can

science best serve mankind in the future.

1.What can we conclude from the recent study?

A. People think highly of science.

B. People hold mixed opinions about science.

C. Science is getting dangerously out of control.

D. Science is used for both good and bad purposes.

2.According to the passage, what will happen if we hold that science is getting beyond control?

A. The development of science will hopelessly slow down.

B. Businesses will have even greater influence on science.

C. The public will lose faith in bringing about a bright future.

D. People will work more actively to put science under control.

3.The discussion should reach beyond scientific societies because _____.

A. scientists have failed to predict the outcomes

B. the ties between different areas need strengthening

C. united efforts are necessary for the development of science

D. people need to work together to prevent the bad use of science

4.What is the main idea of the passage?

A. Science and its applications bring us many dangers.

B. The development of science mostly lies in people's attitudes.

C. Mankind can largely take control of science with their efforts.

D. The future of science will be influenced by the dangerous ideas.

The news of Harper Lee’s second novel broke the internet. Go Set a Watchman would be published in July. Lee became a recluse (隱士)after the publication of her first book, To Kill a Mockingbird, in 1960. Although the author has been out of the public eye for more than 50 years, the wave that followed the announcement showed her novel’s beloved place in the American literary works.

In 1991, The Book of the Month Club and the library of Congress conducted a survey that made readers identify books that had made a difference in their lives. Lee’s book followed only The Bible. Alongside the works of Shakespeare and Twain, To Kill a Mockingbird remains one of the most widely taught books nationwide, reaching an estimated 70% of American public schools. What makes it such a perfect read for young people？

English class is a place where young Americans come to know themselves. In the folds of dusty books, students can make contact with humanity beyond the superficial(膚淺的) conversations of the school hallways. Literature promises relief, a place to figure out one’s problems and get to know oneself better.

To Kill a Mockingbird particularly distinguishes itself in this regard. It speaks in child’s voice without treating its readership as children. People have called it an ‘impossible’ achievement, a children’s book penned in the prose(散文) of a well-educated adult—it’s unlikely that a child like

Scout could exist in the real world. But that’s exactly what makes it such a charming read for young people. It alludes to (轉(zhuǎn)彎抹角地說到)the consciousness of a well-educated adult going through difficult realities, but shows it through the light and playful voice of a curious little girl.

1.In which year might Go Set a Watchman come out?

A. 2015 B. 1960

C. 1910 D. 1991

2.Which book leaves the deepest impression on American readers?

A. Go Set a Watchman B. To Kill a Mockingbird

C. The Bible D. Shakespeare’s works

3.Which of the following statements is right about To Kill a Mockingbird?

A. Its author may be a playful child.

B. It’s a story about a well-educated adult.

C. Young people can see themselves from it.

D. It’s impossible for children like Scout to exist.

4.What is the best title for the text?

A. The Great Writer: Harper Lee B. The Great Young People Novel

C. Voices from Children D. Differences Harper Lee made
