Global warming is the process of earth’s atmosphere heating up. Over the last 100 years, the average temperature of earth’s atmosphere has gone up 1 Fahrenheit. The weather has not changed exactly the same way in every area of the planet. But scientists think that the rise in average temperature is already affecting the earth’s climate.
Many scientists now believe that global warming is caused by cutting down trees, producing more trash, and polluting the environment are some of the reasons that the temperature has gone up. Many scientists believe that the biggest causes of global warming are new human technologies that release greenhouse gases into the atmosphere.
The greenhouse effect is not new. Certain gases in the atmosphere, like carbon dioxide, nitrous oxide and methane, prevent heat energy from escaping back into space. In the past, the climate didn’t change much because nature produced just the right amount of greenhouse gases to deal with it.
Today, most scientists are pretty sure that the rising temperature can’t be blamed on nature. Ever since the industrial revolution in the 1700s, humans have relied on machines for daily life. And many of those machines give off a lot of greenhouse gases. An increase in the release of greenhouse gases from human activities is throwing nature off balance.
The climate is a very complicated thing, but many scientists agree that the rising atmospheric temperature has already damaged the environment. Sheets of ice, called glaciers, are melting in Antarctica and other parts of the globe. As glaciers break off and melt into the oceans, they are adding warm water to the oceans and causing the sea level to rise.
Over the past last 100years, the sea level has risen 6-8 inches around the world. That means land along the coasts is beginning to disappear under water. Bigger and warmer oceans are also adding to other weather problems caused by pollution in the atmosphere. Some places have received more rain, others have had bigger storms and a few areas in the world have experienced unusual droughts.
68. What is mainly talked about in this passage?
A. The melting of glaciers. B. Global warming.
C. The world’s weather. D. The earth’s temperature.
69. What causes global warming according to scientists?
A. Human activities. B. The nature itself.
C. The earth’s atmosphere. D. New discoveries
70. How can greenhouse gases make the globe warm?
A. They keep heat in the atmosphere
B. They let the heat go out into space.
C. They release heat into the air.
D. They can make the other gases warm.
71. From the passage we can see that global warming will bring about _________.
A. the pollution in the atmosphere B. natural disasters
C. population pollution D. the rise of glaciers

JSC Boggs is an artist who makes money.To be exact,he draws money.In the United States he draws dollars,in Britain pounds and in France francs.Each are almost perfect reproductions,apart from the fact that he writes "Bank of Boggs" or another humorous message on them.
When Boggs goes shopping or for a meal,he offers "Boggs dollars" in the payment for what he wants.He also offers real money.It is up to the people selling the goods to take whichever they prefer.
When a shopkeeper or a restaurant owner takes a "Boggs dollar",he or she gives a receipt in return for the things bought.Boggs then sells the receipt at face value to art collectors.This is how he makes actual money for the times when people will not accept his drawings.
The collector uses the receipt to find the person holding the actual "Boggs dollar" and the two talk over what they think would be a fair price.This gives the shop or restaurant owner the chance to make another profit on the goods he or she sold to Boggs.It means Boggs actually gets paid for buying things.And it means that the collector has a unique work of art---each "Boggs dollar" is separately drawn.
Artists like to make us think.What Boggs wants us to think about is the nature of value and money. What is money really worth? Is value of money the same as personal value?

Most American kids love Halloween treats, but a bucket of Halloween candy can be a dentist’s nightmare. Some parents try to get rid of half of the candy after their children go to bed, but dentists say parents also need to separate the good kinds of treats from the bad.
It is not exactly what a child eats that truly matters, but how much time it stays in his mouth. According to pediatric dentist Dr. Kaneta Lott, the most damaging stuff is something that is sticky or very hard and thus stays in the mouth for a long time. This is because we all have bacteria in our mouths. When we eat, the bacteria take our food as their food and produce an acid that destroys the surface of the teeth, causing cavities to form. The longer the food stays in the mouth, the more likely cavities will develop. Therefore, potato chips are worse than candy because they get stuck between teeth. For the same reason, raisins and crackers are not the best choice. Hard candies take a long time to consume and are also a bad choice for Halloween treats
If children really love candy, dentists recommend that they eat chocolate instead. Unlike hard candies, chocolate dissolves quickly in the mouth. Besides, chocolate contains tannins, which help to kill some of the bacteria in the mouth. But no matter what a child eats, brushing after each meal is still the best way to fight cavities.
55.What is the main purpose of this passage?
A. To discuss how cavities can be treated.
B. To point out the problems with Halloween celebrations.
C. To tell parents what sweets are less damaging to their children’s teeth.
D. To teach parents the meaning of Halloween candies for their children.
56.Why are hard candies especially bad for teeth?
A. They may break the child’s teeth.
B. They contain too much sugar.
C. They help bacteria to produce tannins.
D. They stay in the mouth for a long time.
57.According to the passage, which of the following is a better choice for Halloween treats?
A. Chocolate. B. Crackers. C. raisins. D. Potato chips.
58.According to the passage, which of the following is true of tannins?
A. They are produced when the bacteria digest the food.
B. They help to get rid of some bacteria in the mouth.
C. They help chocolate to dissolve more quickly.
D. They destroy the surface of the teeth.

The earth is getting warmer. The planet is suffering. But what can you do about it? Reduce the amount of waste you generate. Use cleaner energy sources and go greener today, starting with these steps:
1. Get a reusable water bottle
Americans buy about 25 billion single-serving plastic water bottles each year. That's an average of 83 bottles per person per year. Plastic bottles take plenty of resources to produce, including fuel for transportation and petroleum to make the plastic. Even recycling bottles uses energy.
2. Eat less meat
You don't need to become a vegetarian to help save the planet. Eating meat just one day less a week can reduce your negative impact on the environment. More water, energy and land are required to produce meat than to produce grain.
3. Switch to energy-efficient light bulbs
Most households use standard incandescent (白炽的) bulbs. But compact fluorescent (荧光的) light bulbs, or CFLs, use 66 percent less energy than standard bulbs, produce just as much light, last up to 10 times longer and don't need to be replaced as often. If every household in the United States replaced just one incandescent light bulb with a CFL bulb, it would equal removing one million cars from the road.
4. Buy organic and local food
Did you know that only 1 percent of pesticides (杀虫剂) applied to crops reach the pests they target? The rest enter the environment. Organic food is grown without the use of pesticides. Organic farming can use 50 percent less energy than traditional farming methods. Buying local food saves on the fuel used to transport food grown elsewhere, thousands of miles across the country or around the world.
5. Recycle your electronics
Everyone knows the importance of recycling glass and plastic, but what about cell phones, computers, CDs and batteries? Electronics are responsible for about 40 percent of toxic (有毒的) heavy metals such as lead and mercury. Check with your city's recycling facilities to see if they take electronics.
72. The readers of this passage are called on to ______.
A. help reduce global warming B. use water in a wise way
C. donate money for charity D. keep a balanced diet
73. What is an advantage of CFLs according to the passage?
A. They use more energy but produce more light.
B. They can last longer so don't need to be replaced often.
C. They cost less than standard incandescent bulbs.
D. They are as energy-efficient as incandescent bulbs.
74. Which of the following figures is correct according to the passage?
A. Every year an American buys 63 plastic water bottles on average.
B. Eating meat one day less a week helps cut environment costs.
C. 99 of the pesticides used on crops is effective in practice.
D. Electronics account for half of poisonous heavy metals on the earth.
75. Which can be the best title for this passage?
A. Why is the earth getting warmer? B. What can we do about pollution? C. How can you lead a greener life? D. Who is to blame for global warming?

A
To most of us, school means classes, teachers, schedules, grades and tests. But for the children at Sudbury Valley School in Massachusetts, school is very different.
Firstly, there are no lessons. All the children, aged between 4 and 19, do whatever they want. There are no teachers, only “staff members”. The idea behind this is that you do not need to make children learn, because children want to learn anyway. “You do not need to say to a three-year-old, ‘Go explore your environment.’ You can’t stop them!” says Daniel Greenberg, a founder of the school. “But if you make children do what you want all day… they will lose all taste of learning.” At Sudbury Valley School, you will find children talking, reading, painting, cooking, working on computers, studying French, playing the piano, climbing trees, or just running around.Two boys spent three years just fishing!
The other way that Sudbury Valley School is different is that the children can decide the rules. Every week, there is a school meeting where both children and staff have one vote each—even the four-year-olds. They decide the school rules, how to spend the school budget (预算,经费), and even which staff they want and do not want anymore.
When the school first opened in 1968, people said it would never work. But today, the school has 200 students, and 80% of its students go on to college. Even the two boys who went fishing all the time have successful careers today. One of them is a musician and the other is a computer scientist.
56. What is the main idea of the article?
A. An unusual school. B. Children’s hobbies.
C. A school without teachers D. Education in the US.
57. What does the school believe?
A. Teachers cannot teach children well.
B. Children learn best when they do what they want to do.
C. Learning is for adults—children should only play.
D. Children should only learn about one thing at a time.
58 What does Daniel Greenberg say about three-year-olds?
A. They love learning.
B. They are very naughty.
C. They want to be outside all the time.
D. They are too young to learn anything.
59. Who has the most power in the school meeting?
A. The older children have more power than the younger children.
B.A child has more power than an adult.
C. The younger children have more power than the older children.
D. Everybody has equal power.
