C
If you have to miss a meal a day, which meal will cause you fewest health problems if you don’t eat it? If you have to make a decision of this type, most people (especially very busy people) will choose to skip breakfast.
However, many experts in the field of health consider breakfast ( the meal which “break” you “fast” ) to be the most important  meal of the day. If we eat a good breakfast, they say, we will have the energy and nutrients (營養) we need to begin our working day with vigor(活力) and stay hopeful with good honor. However, many people skip breakfast or substitute a cup of coffee for a well balanced meal. What happens if we ignore the importance of breakfast?
One recent study conducted in the United States tested a large number of people. Participants(參加者) included both males and females who ranged in age from 12 to 83. The results showed that if a person eats an adequate(豐富的) breakfast, he or she will work more efficiently(效率高地) and more productively than if he or she skips breakfast or eats a very poor breakfast. This fact appears to be especially true if a person’s work involves mental(腦力的) activities. The study showed that if school-children eat fruit, eggs, bread and milk before going to school, they will learn more quickly and will be able to concentrate on their lessons for a longer period of time than if their breakfast is inadequate(不豐富).
The study also showed that contrary to what people believe, if you skip breakfast, you will not lose weight. This is because people become so hungry if they skip breakfast that they eat too much for lunch and end up gaining weight instead of losing. So remember, if you want to lose weight, skipping breakfast will not help you. You will likely lose more weight if you decrease your other meals.
【小題1】 According to experts, breakfast is the most important meal of the day because _____.

A.a good breakfast breaks you down fast
B.you’ll lose weight quickly if you skip breakfast
C.breakfast provides what a person needs to work
D.after a long night, you’ll feel very hungry
【小題2】The underlined part “substitute a cup of coffee for a well balanced meal”(Para. 2) probably means _______.
A.to exchange a cup of coffee for a well balanced meal.
B.To drink a cup of coffee instead of a well balanced meal.
C.To change a cup of coffee into a well balanced meal.
D.To regard a cup of coffee as a well balanced meal.
【小題3】The example of school-children in para.3 shows that _______.
A.school-children will be quick and attentive all day if they eat breakfast
B.a proper breakfast will make mental workers more efficient
C.fruit, eggs, bread and milk are the best breakfast for mental workers
D.school-children who have breakfast are much brighter than those who don’t
【小題4】Which of the following is NOT true according to Para. 4?
A.Some people skip breakfast because they want to be slimmer.
B.Most people who skip breakfast actually eat more for lunch.
C.People put on weight because they eat too much breakfast.
D.Skipping breakfast won’t help people who want to lose weight.
【小題5】The best title of the passage is _______.
A.How to Lose WeightB.What’s a Healthy Diet
C.Surprising Results of a StudyD.Breakfast – A Meal That Breaks You Fast

What is the connection between violence and sports? Psychologists(心理學家) say that there are many reasons for violence at sports events. One is alcohol(酒精). Many fans drink a lot at games. When people drink, they are more likely to do abnormal things. Psychologist Dennis Brock says, “Quiet people become loud. Normally nonviolent people become destructive.”
David Sampson, a sports sociologist, agrees, “These are often celebratory riots(暴亂)— a large number of very happy people mixed in with large amounts of alcohol. They don’t often seem dangerous in the beginning, but things get violent quickly.”
Another reason for violence at sports events is the crowd itself. When individuals are in a large group of people, they can lose their sense of personal responsibility. Edward Hirt, a social Psychologist, says that research shows that people do things in crowds that they would never do alone. People in crowds feel that no one knows who they are. Crowds also make people feel powerful. They stop making personal decisions. They just follow the crowd. Social psychologists call this a “mob mentality.”
Dave Zarifis, head of public safety at Northern Iowa University says, “Some people don’t even come to celebrate. They want to drink hard and make trouble. Someone does something stupid, and it grows from there. You get a mob mentality. People think it’s OK to do almost anything. They think, ‘There are so many of us and not enough of them.’ ”
Social psychologist Dr. Sharon Kennedy says that there are a few things officials can do to prevent violence. Making sure that an area is not overcrowded is very important. Officials should also think of games as “big parties.” Then they will prepare differently. Kennedy says that in Great Britain they are controlling the problem with cameras in all the stadiums. “When you know someone is watching, you are much less likely to behave badly.”
【小題1】Which of the following best gives the main idea of the first two paragraphs? 

A.There’s a connection between violence and sports
B.There are many reasons for violence at sports events.
C.One cause of violence at sports events is alcohol.
D.David Sampson and Dennis Brock have the same opinion.
【小題2】Which of the following does NOT belong to a “mob mentality”?
A.“ No one knows I’m doing this.”
B.“ It’s safe to do what many people are doing.”
C.“There are so many of us and not enough of them.”
D.“I must drink some alcohol to stop myself feeling shy.”
【小題3】How many experts are quoted by the writer of this passage?
A.Five. B.Four.C.Three.D.Two.
【小題4】The last paragraph is mainly about ______.
A.how to turn games into big parties
B.how to prevent violence at sports events
C.why to fix cameras in stadiums
D.how to avoid oneself behaving badly
【小題5】What lesson can we learn from this passage?
A.Never drink any alcohol no matter where you are.
B.Whenever you are watching a game, you should keep quiet.
C.Never follow blindly no matter how many people are doing something.
D.Be careful when you are at a stadium because there are cameras there.

Each new school year brings fresh reminders of what educators call the summer learning gap. Some call it the summer learning setback. Simply speaking, it means the longer kids are out of school, the more they forget. The only thing they might gain is weight.

Most American schools follow a traditional nine-month calendar. Students get winter and spring breaks and about ten weeks of summer vacation. Some schools follow a year-round calendar. They hold classes for about eight weeks at a time, with a few weeks off in between. The National Association for Year-Round Education says there were fewer than three thousand such schools at last count. They were spread among forty-six of the fifty states.

But many experts point out that the number of class days in a year-round school is generally the same as in a traditional school. Lead researcher Paul von Hippel said, "Year-round schools don't really solve the problem of the summer learning setback. They simply spread it out across the year."

Across the country, research shows that students from poor families fall farther behind over the summer than other students. Experts say this can be prevented. They note that many schools and local governments offer programs that can help.

But calling them "summer school" could be a problem. The director of the summer learning center at Johns Hopkins, Ron Fairchild, said research with groups of different parents in Chicago and Baltimore found that almost all strongly disliked the term summer school”. In American culture, the idea of summer vacation is connected to beliefs about freedom and the joys of childhood. The parents welcomed other terms like "summer camp," "enrichment," "extra time" and "hands-on learning."

1.According to the first paragraph the summer learning gap         .

A.helps children to gain weight

B.leads children to work harder

C.improves children’s memories

D.affects children’s regular studies

2.Compared to traditional schools, students in the year-round ones          .

A.perform better and have more learning gains

B.have much less time for relaxation every year

C.have generally the same number of class days

D.hold more classes with more free weeks off

3.Which of the following statements is true?

A.Students from poor families often fall behind after the vacation.

B.Year-round schools can solve the problem of the learning gap.

C.There are schools in each state following a year-round calendar.

D.Nothing can help the students who fall behind after the vocation.

4.Why did almost all parents dislike the term “summer school”?

A.They cherish the children’s rights of freedom very much.

B.They are worried about the quality of the “summer school”.

C.They want their children to be forced to make up the gap.

D.They can’t afford to the further study during vacation.

5.What would be the best title of this passage?

A.Opening Summer Camps

B.Forbidding Summer Schools

C.Spreading Year-Round Education

D.Minding the Summer Learning Cap

Valuing water

Human beings use a little less than half the water available worldwide. Yet shortages and droughts(干旱) are causing starvation and poverty in some areas, and industrial and agricultural by-products are polluting water supplies. Since the world’s population is expected to double in the next 51 years, many experts think we are on the edge of a widespread water crisis.

But that doesn’t have to be the result. Water shortages do not have to trouble the world—if we start valuing water more than we have in the past. Just as we began to value petrol more after the 1970s oil crisis, today we must start looking at water from a fresh economic view. We can no longer afford to consider water a nearly free resource of which we can use as much as we like in any way we want.

Instead, for all uses except the demand of the poor, governments should price water to reflect its real value. This means charging a fee for the water itself as well as for the supply costs.

Governments should also protect this source by providing water in more economically and environmentally sound ways. For example, often the cheapest way to provide irrigation(灌溉) water in the dry places is through small-scale projects, such as gathering rainfall in depressions(凹地) and pumping it to nearby cropland.

No matter what steps governments take to provide water more efficiently, they must change their ways to use water. Rather than control hundreds or even thousands of local, regional agencies that watch water use, countries should set up central authorities to manage water policy.

65. What is the real cause of the potential water crisis?

A. Only half of the world’s water can be used.

B. The world population is increasing faster and faster.

C. Half of the world’s resources have been seriously polluted.

D. Human beings have not placed sufficient value on water resources.

66.We can conclude from the passage that the water problem______.

A. is already serious in certain parts of the world

B. has been exaggerated by some experts in the field

C. poses a challenge to the technology of building reservoirs

D. is underestimated by government organizations at different levels

67.According to the author, the water price should______.

A. be reduced to the minimum

B. stimulate domestic demand

C. equal its real value

D. take into account the occurrences of droughts.
