Christian Eijkman, a Dutch doctor, left the Netherlands for the island of Java. Many people on the island had a disease called beri-beri. He was going there to try and find a cure.
At first, Eijkman thought some kind of germ (细菌) caused beri-beri. He raised some chickens. He didn’t eat them, but made experiments on them. The local people were quite surprised at that. One day he noticed that his chickens became sick when they were fed the food most Javanese ate — refined white rice (精炼米). When he fed them with unrefined rice, also known as brown rice, they recovered. Eijkman realized that he had made an important discovery — that some things in food could prevent disease. These things were named vitamins. The Javanese were not getting enough vitamins because they had actually removed the part that contains vitamins. Later, other diseases were also found to be caused by the lack of vitamins in a person’s food.
Today many people know the importance of vitamins and they make sure they have enough vitamins from the food they eat. If they don’t, they can also take vitamin pills.Christian Eijkman went to the island of Java to ______.

Let children learn to judge their own work. A child learning to talk does not learn by being corrected all the time :if corrected too much, he will stop talking. He notices a thousand times a day the difference between the language he uses and the language those
Around him use. Bit by bit .he makes the necessary changes to make his language like other people's. In the same way, children learn to do all the other things: they should learn to do without being taught, such as to walk, run, climb, whistle, ride a bicycle—compare their own performances with those of more skilled people, and slowly make the needed changes. But in school we never give a child a chance to find out his mistakes and correct them for himself. We do it all for him. We act as if we thought that he would never notice a mistake unless it was pointed out to him, or correct it unless he was made to .Let him work out, with the help of other children if he wants it, what this word says, what the answer is to that problem, whether this is a good way of saying or doing this or not.
If it is a matter of right answer, as it may be in mathematics or science, give him the answer book. Let him correct his own papers. Why should we teachers waste time on such routine（常规）work? Our job should be to help the child when he tells us that he can’t find the way to get the right answer .Let the children learn what all educated persons must some day learn ,how to measure their own understanding, how to know what they know or do not know.According to the passage ,the best way for children to learn things is by______

Sitting and eating quietly on his father’s lap, the 18-month-old was oblivious to the infection in his veins(血管).But his father a strong farmer, knew only too well. It was the same one that killed his wife four month ago, leaving him alone with four children. The man started to cry.
“When my wife died, I thought ,well, it is from God, but at least I have him.” he said. “Then I learned he is sick, too. I asked if there was medicine and the doctors said no.
HIV and AIDS have quietly arrived in this land. They remain almost completely underground, hidden in ignorance（无知）and shame.
The father of the infected 18-month-old said his village teacher had never talked about AIDS. Nearly a year of tests on the father have found no HIV, and the old children are clear, but his smallest child tested positive（阳性）at ten months.
Six years earlier, his wife lost a baby and have several transfusions in Pakistan. After she became sick and was found to be infected, “I told the family her blood was not good and to avoid eating with her.” he said. “And I told them not to kiss his son, he burst into tears.
“I don’t know what to do,” he said; “I have sacrificed so much since my marriage.. I mortgaged (抵押)half my land to pay for her medical care.”
The father can do little for his son but keep his secret. There are no AIDS treatment centers in Afghanistan, only a single secret clinic in the capital that just monitors the disease, and no drugs are available.The underlined part “was oblivious to” in Paragraph 1 can best be replaced by______.

Each high school has its own policy. One good example is that some high schools require all students to wear uniforms, while others do not. I have been to both types of schools, and if I have to decide which one is better, I will pick the former.
Perhaps every student has this experience: once you are in your school uniforms, you will care more about your own behavior. Uniforms give you an identity that always reminds that you belong to a group. What you do will not only represent yourself, but also the group you belong to, as well as the people with you. In other words, you carry the responsibility to maintain the honor of the group. When you are in your own clothes, it doesn’t matter for you to behave badly in public, but when in your uniform, it does. For high school students, who are not adults yet, this is a good way to shape their behavior.
Moreover, uniforms create an atmosphere of equality. While permitted to wear their won clothes, students may pay much attention to what they wear, in order to show how rich their families are. While in uniforms, all students, rich or poor, look the same, and will be treated equally.
Besides, free from the desires to gain what is new in the shopping mall, wearing uniforms helps students to concentrate on their study.
For all the reasons above, I believe that it is a better choice for high school students to wear uniforms. They can wear them after school or on weekends. According to the author, high schools that require students to wear uniforms______.
| A．are more attractive to students |
| B． are more strict with students |
| C． carry out a better policy |
| D． admit more excellent students. |
How many reasons does the author give to support his or her ideas?
| A．two | B．three | C．four | D．five |
According to Paragraph 2, wearing uniforms helps students_______.
| A．focus on their study |
| B．become responsible |
| C．build up their confidence |
| D．find the group they belong to |
What would be the best title for the passage?
| A．A wise choice, to wear school uniform |
| B．An honor, to wear your school uniform |
| C．A difficult choice, in school uniform or not? |
| D．A difficult choice, which school should we pick? |

The flag, the most common symbol(象征) of a nation in the modern world, is also one of the most ancient. With a clear symbolic meaning, the flag in the traditional form is still used today to mark buildings, ships and other vehicles related to a country.
The national flag as we know it today is in no way a primitive(原始的)artifact. It is, rather, the product of thousands of years' development. Historians believe that it had two major ancestors, of which the earlier served to show wind direction.
Early human beings used very fragile houses and boats. Often strong winds would tear roofs from houses or cause high waves that endangered travelers .People's food supplies were similarly vulnerable. Even after they had learned how to plant grains, they still needed help from nature to ensure good harvests. Therefore they feared and depended on the power of the wind, which could bring warmth from one direction and cold from another.
Using a simple piece of cloth tied to the top of a post to tell the direction of the wind was more dependable than earlier methods, such as watching the rising of smoke from a fire. The connection of the flag with heavenly power was therefore reasonable. Early human societies began to fix long pieces of cloth to the tops of totems(图腾) before carrying them into battle. They believed that the power of the wind would be added to the good wishes of the gods and ancestors represented by the totems themselves.
These flags developed very slowly into modern flags. The first known flag of a nation or a ruler was unmarked: The king of China around 1000 B.C. was known to have a white flag carried ahead of him. This practice might have been learned from Egyptians even further in the past, but it was from China that it spread over trade routes through India, then across Arab lands, and finally to Europe ,where it met up with the other ancestor of the national flag.
