Diet Coke, diet Pepsi, diet pills, no-fat diet, vegetable diet… We are surrounded by the word “diet” everywhere we look and listen. We have so easily been attracted by the promise and potential of diet products that we have stopped thinking about what diet products are doing to us. We are paying for products that harm us psychologically and physically.

Diet products weaken us psychologically. On one level, we are not allowing our brain to admit that our weight problems lie not in actually losing the weight, but in controlling the consumption of fatty, high-calorie（卡）, unhealthy foods. Diet products allow us to jump over the thinking stage and go straight for the counter instead. All we have to do is to swallow or recognize the word “diet” in food brands.

 On another level, diet products have greater psychological effects. Every time we have a zero-calorie drink, we are telling ourselves without our awareness that we don’t have to work to get results. Diet products make people believe that gain comes without pain, and that life can be without resistance and struggle.

 The danger of diet products lies not only in the psychological effects they have on us, but also in the physical harm that they cause. Diet foods can indirectly harm our bodies because consuming them instead of healthy foods means we are preventing our bodies from having basic nutrients(营养成分). Diet foods and diet pills contain zero calorie only because the diet industry has created chemicals to produce these wonder products. Diet products may not be nutritional, and the chemical that go into diet products are potentially dangerous.

 Now that we are aware of the effects that diet products have on us, it is time to seriously think about buying them. Losing weight lies in the power of minds, not in the power of chemicals. Once we realize this, we will be much better able to resist diet products, and therefore prevent the psychological harm that comes from using them.

Humankind has tried to improve its standard of living since the very beginning of civilization. Back then, as well as today, providing food and security was the basic task for a person. However, nowadays the range of required goods has expanded significantly. People feel the need for not only some primary things, such as a piece of bread and a roof over their heads, but also for various facilities and luxuries. Providing humanity with these things is connected to the use of natural resources, which requires energy. In turn, the common sources of energy we use today cause pollution, so economic growth is almost inevitably associated with environmental damage.

Economic growth is the increase in numbers of goods and services produced over time by an economy, and it's calculated in terms of real Gross Domestic Product (GDP). Before growth is calculated, inflation(通货膨胀) is adjusted in order to take into account its misleading effect on the price of goods and services. Economic growth can also be explained as the increase in expected output, which results from an increase in actual output, or total demand.

There are certain aspects of economic growth which affect the environment. The first of these is the fact that in order to produce more goods and products, at a faster rate, the construction of large industrial plants is required. These plants produce a lot of waste, leading to the pollution of water and the atmosphere, which may cause negative long- term health effects to nearby populations of animals, or people. They also lead to global warming.

Industrial manufacturing leads to the constantly increasing energy consumption. The traditional energy sources, which are commonly used nowadays, are considered to be the greatest polluters to the environment. There also exist so-called eco-friendly sources of energy. They are sometimes preferred but replacing the traditional sources with them also requires time, during which people have to make some sacrifices to support these undertakings.

In order to produce economically practical energy, a sometimes significant transformation of the natural site is often inevitable. This is expensive and, has harmful effects on the environment. Application of wind energy would Block airflows' natural speed, which is the reason for their decrease in strength, after crossing the windmill. Consequently, the pressure balance that is brought about by this current will be affected, and it is important to remember that the environment and weather conditions are directly affected by atmospheric pressure.

For these reasons, bringing about economic growth without resulting in any environmental damage is impossible.

1.What does the passage mainly talk about?

A．Pollution caused by plant construction

B．Effects of windmills on the environment

C．Economic growth and human civilization

D．Economic growth and environmental damage

2.According to the passage, the author holds the opinion that ____.

A．economic growth should be calculated in terms of GDP

B．use of natural resources causes no damage to the environment

C．industrial manufacturing may cause damage to the environment

D．a windmill is a perfect way to produce economically practical energy

CP (Central Point)     P (Point)      Sp (Sub-point次要点)    C (Conclusion)

It is time for students to sell such things as chocolate bars and greeting cards to raise money for their school, class or club. It is inevitable that they will knock on your door and you will easily hand over your cash for overpriced items that you really do not want. That is okay, though, because there are many reasons why children should be allowed to raise money for their schools and clubs.

Fundraising（募集资金） is a great way to help children learn social skills. It is not easy to go up to a complete stranger and ask him for his money. They have to nicely ask for help, show the interested buyer what they have to offer and explain how it will help them in school. If someone refuses to buy an item, that child has to take the failure in stride(不特别费力地), and that is a learning lesson as well.

Students can learn how to deal with money by fundraising. Of course, it might seem safer for us to take charge of our children’s earnings from their fundraising before it is turned into the school. However, by making them keep track of it, count it, and make sure everyone pays the right amount, they are learning an important lesson. Dealing with money is important to know about when they are older.

Fundraising helps improve their schools. It is the children’s school. They have to learn there and grow there. Why not let them help in making it a better place?

Fundraising allows for more life experiences for the child. The raised money is used towards things like parties, trips, or for the music club to go to see a Broadway play. The children receive the rewards for their hard work at raising the money. Without fundraising, these field trips and special school memories would be missed.

In a word, fundraising helps children a lot in many ways.

1.The underlined word “inevitable” in the first paragraph means “_______”.

A. 不可能的         B. 不恰当的         C. 不可避免的      D. 不现实的

2.One of the important indications that children are grown up is that __________.

A. children can deal with money        

B. children learn to care for others

C. children make a date with friends of the other sex      

D. children like to make up

3.The author thinks that fundraising _______.

A. adds to the family’s burden              B. wastes the learning time

C. helps to develop the children’s character D. builds up the children’s bodies
