There are some very good things about open education. This way of teaching allows the students to grow as people, and to develop their own interests in many subjects. Open education allows students to be responsible for their own education, as they are responsible for what they do in life. Some students do badly in a traditional classroom. The open classroom may allow them to enjoy learning. Some students will be happier in an open education school. They will not have to worry about grades or rules. For students who worry about these things a lot, it is a good idea to be in an open classroom.
But many students will not do well in an open classroom. For some students, there are too few rules. These students will do little in school. They will not make good use of open education. Because open education is so different from traditional education, these students may have a problem getting used to making so many choices. For many students it is important to have some rules in the classroom. They worry about the rules even when there are no rules. Even a few rules will help this kind of students. The last point about open education is that some traditional teachers do not like it. Many teachers do not believe in open education. Teachers who want to have an open classroom may have many problems at their schools.
You now know what open education is. Some of its good points and bad points have been explained. You may have your own opinion about open education. The writer thinks that open education is a good idea, but only in theory. In actual fact, it may not work very well in a real class or school. The writer believes that most students, but of course not all students, want some structure in their classes. They want and need to have rules. In some cases, they must be made to study some subjects. Many students are pleased to find subjects they have to study interesting. They would not study those subjects if they did not have to.

A small piece of fish each day may keep the heart doctor away. That’s the finding of a study of Dutch men in which deaths from heart disease were more than 50 percent lower among those who consumed（消费） at least an ounce of salt water fish per day compared to those who never ate fish.
The Dutch research is one of three human studies that give strong scientific support to the long held belief that eating fish can provide health benefits, particularly to the heart.
Heart disease is the number-one killer in the United States, with more than 550,000deaths occurring from heart attacks each year. But previous research has shown that the level of heart disease is lower in cultures that consume more fish than Americans do. There are fewer heart disease deaths, for example, among the Eskimos of Greenland, who consume about 14 ounces of fish a day, and among the Japanese, whose daily fish consumption averages more than 3 ounces.
For 20 years, the Dutch study followed 852 middle-aged men, 20 percent of whom ate no fish.
At the start of the study, average fish consumption was about two-thirds of an ounce each day, with more men eating lean fish than fatty fish.
During the next two decades, 78of the men died from heart disease , The fewest deaths were among the group who regularly ate fish, even at levels far lower than those of the Japanese of Eskimos, This relationship was true regardless of other factors such as age, high blood pressure, or blood cholesterol(胆固醇)levels.Which of the following is NOT true according to the passage?
| A．The Dutch research has proved that eating fish can help to prevent heart disease. |
| B．People who regularly eat fish never suffer from heart disease. |
| C．Heart disease causes more deaths in America than any other disease. |
| D．There is a low level of heart disease in such countries as Japan and Greenland. |
The passage is mainly about______.
| A．the changes in people’s diet |
| B．the daily fish consumption of people in different cultures. |
| C．the high death rate of disease in some countries. |
| D．the effect of fish eating on people’s health |
We can infer from the passage that there are fewer heart disease deaths____.
| A．in Dutch |
| B．in America |
| C．in countries with high consumption of fish |
| D．in countries with good production of fish |
The phrase“this relationship (paragraph 6) refers to the connection between ____ and the level of heart disease.”
| A．the amount of fish eaten |
| B．regular fish-eating |
| C．the kind of fish eaten |
| D．people of different areas |
I was 230 pounds this spring and I decided to get down to a healthier 200.In a house full of food，including snacks bought for my 7yearold sons，I had a hard time cutting calories. Then I noticed my neighbors were having diet meals (减肥餐)．I decided to do the same，knowing I would never be able to stick to a diet if I had to do the buying and cooking myself. I was looking for food that I could afford but I might take a diet more seriously if it hurt me in the wallet.
After online searches，I decided to compare the offerings of four companies：Zone Manhattan，Chefs Diet，NuKitchen and eDiets. All four would send the meals to my door. Three send food daily，while eDiets sends a large package once a week. There were dozens of companies I could have chosen.Research suggests that the economic crisis has made diet programs less tempting.Consumers prefer doityourself diets with foods bought from the supermarket.
NuKitchen regards itself as the “personal chef”．I ordered the fiveday plan ($230.53) and the taste was disappointing. I neither lost nor gained weight on the food.
eDiets promises “healthy，delicious meals sent to your door”．I ordered five breakfasts，five lunches and five dinners. My total cost was $119.70，or less than $25 a day. Overall，the food from eDiets was better than that from NuKitchen.
Chefs Diet charged $380.99 for seven days，making it the most expensive of the four services.I never tasted anything terrible，but I never tasted anything that made me want to renew for a second week.
Zone Manhattan charged $349.80，with tax，for a week’s supply of food，or about $50 a day.I liked the food so much that I lost six pounds in the first four days on the diet.When the author began to have diet meals，she________.
| A．was 200 pounds |
| B．didn’t have any children |
| C．worked as a cook in a company offering diet meals |
| D．didn’t believe she could stick to a diet if she had to cook herself |
What does the underlined word “tempting” in Paragraph 2 mean?
| A．Attractive. | B．Expensive. | C．Delicious. | D．Useful. |
Which of the four companies’ food cost the least daily?
| A．Zone Manhattan’s. | B．Chefs Diet’s. |
| C．NuKitchen’s. | D．eDiets’． |
We can learn from the passage that________.

| D．Zone Manhattan sends food once a week |
Many parents watch the news or other shows as children play nearby. But new research shows that even when the television is just background noise，it may be disruptive to a child’s normal development.
It’s estimated that 75 percent of very young children in the United States live in homes where the television is on most of the time，even though the kids often aren’t watching it. The University of Massachusetts researchers recently studied how TV background noise might affect young children. The study looked at 50 1，2and 3yearolds. Each child came to a lab with a parent and was allowed to play for an hour with various toys. For half the time，a television was on in the room，showing the adult game show as well as advertisements. During the other half hour，the TV was turned off.
As expected，the children paid little attention to the adult television show，glancing at it for less than a few seconds at a time，and less than once a minute. Even so，the distraction (分心) of the background noise had a significant effect on how children at every age played. When the television was on，the children played with each toy for far shorter periods of time，and focused attention during play was also shorter compared to how they played when the TV was off.
Researchers said that even though the children aren’t interested in the show，background TV affects their ability to do various types of play. The finding is important because many wellmeaning parents who wouldn’t let their young children watch television may not realize that even adult programs that don’t interest children still can have an effect.
“Background TV is potentially a chronic (长期的) environmental risk factor affecting most American children，” said the lead author of the study. “Parents should limit their young children’s exposure (接触)．”We know from the passage that________.
| A．background TV noise has little effect on adults |
| B．most young children in America live in homes exposed to TV noise |
| C．the effect of background TV noise on children is immediate |
| D．most parents in America wouldn’t let their children watch TV |
The underlined word “disruptive” in Paragraph 1 is closest in meaning to________.
| A．harmful | B．important | C．similar | D．related |
In the study，the children________.
| A．were all 3yearolds | B．were asked to watch adult TV shows |
| C．played for an hour while the TV was on | D．played with more than one toy |
What does the study show?
| A．Children pay much attention to adult TV shows. |
| B．Children should be allowed to watch TV for kids only. |
| C．The background TV noise affects children’s ability to focus. |
| D．The more toys a child has，the shorter time he plays with each one. |
London Underground
The world’s first subway was built in London in 1863. At the time，the government was looking for a way to reduce traffic problems in the city of London. The poor areas of the city were so crowded with people that it was almost impossible for horse carriages to get through. The city officials were interested in trying to make it possible for workers to live outside of London and travel easily to work each day. If people had a cheap and convenient way that they could depend on to go to and from work， they would relocate their homes outside of the city. This would help ease(减轻) the pressure of too many people living in the poor parts of London. From these problems，the idea of the London Underground，the first subway system，was born.
The plans for building the Underground met with several problems and delays，but the fast track was finally opened in January 1863. A steam train pulled the cars along the fast underground track which was 6 kilometers (3.7 miles) long. About 30，000 people got on the subway the first day. Riders were treated to comfortable seats (standing up while the train was moving was not allowed)， and pleasant decorations inside each of the cars. However， the smoke from the engine soon filled the air in the tunnels with ash and soot(煤灰)， as well as chemical gases. Fans had to be put in the tunnels later to keep the air clean enough for people to breathe. Even with its problems，riding in the Underground did catch on. It carried 9 million riders in its first year.How did the London Underground solve the smoke problem？
| A．It made the tunnels larger. |
| B．It put fans in the tunnels. |
| C．It cleaned the chemical gases in the tunnels. |
| D．It reduced the number of passengers riding in the train. |
What led the British government to build the London Underground？
| A．Traffic jams and pollution. |
| B．Population and pollution. |
| C．Overcrowding and traffic jams. |
| D．The poverty and subway problems. |
Which of the following is TRUE？
| A．To relocate the workers’ homes outside London，the government built the subway. |
| B．There were so many problems and delays that in 18th century the first subway opened. |
| C．The subway greatly eased the pressure of traffic. |
| D．There were not enough seats for the passengers the first day the subway opened. |
The underlined phrase “catch on” most probably means “______”.
| A．be troublesome | B．become popular and fashionable |
| C．keep up with | D．seize |
For a long time, a boy wondered why his next-desk-pal was always the first in the class, whereas he could only rank the 21st. At home, he asked his mom, “Am I more stupid than other kids? How come I always lag behind? I just can’t come up with an answer.” Mom was aware that her son’s self-respect had been damaged by the ranking system, but she didn’t know what to say to help.
She was tempted (想要) to say that intelligence differs and that yes, her son’s friend really was the smarter boy. But that would have so upset her son. Thank goodness she resisted the temptation to say it.
Her son and his friend went on to high school that year, but despite trying as hard as he could, her son’s friend still outdid him. But she was proud of her boy for his hard work, sincerely proud. It was around this time she decided to take him on a trip to the seaside. On the trip, she at last found an answer for him.
Today her son no longer cares about rankings. He doesn’t have to, for he himself is now the top of the class – at the top national university he attends. Invited to speak to his old high school, he mentioned a valuable childhood experience: “Once, on a trip to the sea, my mother and I were lying on the beach. She pointed to the sea and said to me: ‘Do you see the seabirds fighting for food out there? When a wave comes near, the little birds rise quickly. The “clumsy” seagulls (海鸥) are far less agile (灵活的) and have to struggle to get away from the wave. But these “clumsy” birds prove to have the biggest, strongest wings, which open the widest and allow the bird to travel the furthest. When the season changes, they leave for foreign shores, leaving the little birds behind. Son, I have a feeling that you are one of those seagulls.” From the first paragraph, we could conclude the mother ______.
| A．knew her son was not bright enough |
| B．saw the negative effects of the ranking system |
| C．decided to help with her son’s school work |
| D．was troubled by her son’s low rankings |
The mom was glad she didn’t give an answer at first because ______.
| A．she knew her son would forget his rankings soon |
| B．she felt intelligence doesn’t mean everything |
| C．she knew he was not strong enough for the truth |
| D．she wanted to avoid another blow to her son’s self-respect |
The story conveys the message that ______.
a. only rankings show intelligence
b. hard work and confidence can lead to a change in rankings
c. parents should see children’s strengths and encourage them
d. competition between students is good for society
| A．bc | B．cd | C．abc | D．bcd |
