Polyester is now being used for bottles. ICI, the chemicals and plastics company, believes that it is now beginning to break the grip of glass on the bottle business and thus take advantage of this huge market.
All the plastics manufacturers have been experiencing hard times as their traditional products have been doing badly world-wide for the last few years. Between 1982 and 1984 the Plastics Division of ICI had lost a hundred and twenty million dollars, and they felt that the most hopeful new market was in packaging, bottles and cans.
Since 1982 it has opened three new factories’ producing “Melinar” , the raw material from which high quality polyester bottles are made.
The polyester bottle was born in the 1970s, when soft drinks companies : like Coca Cola started selling their drinks in grant two-litre containers. Because of the build-up of the pressure of gas in these large containers, glass was unsuitable. Nor was PVC, the plastic which had been used for bottles since the 1960s, suitable for drinks with gas in them. A new plastic had to be made.
Glass is still cheaper for the smaller bottles, and will continue to be so unless oil and plastic become much cheaper, but plastic does well for the larger sizes.
Polyester bottles are virtually unbreakable. The manufacturers claim they are also lighter, less noisy when being handled, and can be re-used. Shopkeepers and other business people are unlikely to object to a change from glass to polyester, since these bottles mean few breakages, which are costly and time-consuming.The public, though, have been more difficult to persuade. ICI’s commercial department is developing different bottles with interesting shapes, to try and make them visually more attractive to the public.
The next step could be to develop a plastic which could replace tins for food. The problem here is the high temperatures necessary for cooking the food in the container.
1.Plastics of various kinds have been used for making bottles
A. since 1982.
B. since the 1970s but only for large bottles.
C. since the 1960s but not for liquids with gas in them.
D. since companies like Coca Cola first tried them.
2. Why is ICI’s Plastics Division interested in polyester for bottles?
A. The other things they make are not selling well.
B. Glass manufacturers cannot make enough new bottles.
C. They have factories which could be adapted to make it.
D. The price of oil keeps changing.
3. Why aren’t all bottles now made of polyester? (Câu này mk hk chắc)
A. The price of oil and plastic has risen.
B. It is not suitable for containing gassy drinks.
C. The public like traditional glass bottles.
D. Shop keepers dislike re-usable bottles.
4. Manufacturers think polyester bottles are better than glass bottles because they
A. are cheaper.
B. are more suited to small sizes.
C. are more exciting to look at.
D. do not break easily.
5. Plastic containers for holding food in the same way as cans
A. have been used for many years.
B. are an idea that interests the plastics companies.
C. are possible, but only for hot food.
D. are the first things being made in the new factories.
Fill in each blank with one suitable word.
Energy is one of the problems that many people are interested in. It is not an unfamiliar word. It is heard, said, discussed day after day. It is close to everyone's (29)daily life. You turn on the lamp and it is energy that gives you light. You turn on a TV and it is energy that gives you pictures and sound. You ride a motorcycle and it is energy that gives you movement. You (30)cook your meals and it is energy that gives you heat to boil rice.
The problem is that the demand for energy is rising and that the price of energy isgetting (31)higher and higher. The supply of energy on earth is limited. It cannot provide us all forever. The shortage of energy in the future is inevitable. Therefore, (32)saving energy is a must if we want to continue to live in a safe and sound world.
Coal, oil, and natural gas supply modern civilization with most of irs power. However, not only are supplies of these fuels limited, but they are a major source of pollution. Therefore, it's important to improve, explore and develop such alternative energy sources as nuclear, water, solar and wind power. Each of these alternatives, however, has advantages and disadvantages.
Nuclear power plants efficiently produce large amounts of electricity without polluting the atmosphere; however, they are costly to build and maintain, and they create the difficult problenı of what to do with nuclear waste. Hydroelectric power is inexpensive and environmentally safe, but impractical for communities locnted far from moving water.Wind power is a pollution-free source renewable energy but it cannot be used many parts of the world where there is insufficient wind. Solar power renewable, it does not cause pollution and it does not add the earth's heat load. However, it ia dilficult to coilect and store. Solar power also requir eensive equipnent
Every source of energy has its disadvantages. One way to minimize them is to use less energy. Conservation efforts coupled with renewable energy resoucs wll ensure supplies of clean, affordable energy for humanity's future.

It used to be that people would drink coffee or tea in the morning to pick them up and get them going for the day. Then cola drinks hit the market. With lots of caffeine and sugar, these beverages soon became the pick-me-up of choice for many adults and teenagers. Now drink companies are putting out so-called "energy drinks." These beverages have the specific aim of giving tired consumers more energy.
One example of a popular energy drink is Red Bull. The company that puts out this beverage has stated in interviews that Red Bull is not a thirst quencher. Nor is it meant to be a fluid replacement drink for athletes. Instead, the beverage is meant to revitalize a tired consumer’s body and mind. In order to do this, the makers of Red Bull, and other energy drinks, typically add vitamins and certain chemicals to their beverages. The added chemicals are like chemicals that the body naturally produces for energy. The vitamins, chemicals, caffeine, and sugar found in these beverages all seem like a sure bet to give a person energy.
Health professionals are not so sure, though. For one thing, there is not enough evidence to show that all of the vitamins added to energy drinks actually raise a person’s energy level.
Another problem is that there are so many things in the beverages. Nobody knows for sure how all of the ingredients in energy drinks work together.
Dr. Brent Bauer, one of the directors at the Mayo Clinic in the US, cautions people about believing all the claims energy drinks make. He says, “It is plausible if you put all these things together, you will get a good result.” However, Dr. Bauer adds the mix of ingredients could also have a negative impact on the body. “We just don’t know at this point,” he says.
Question 33: According to the passage, what makes it difficult for researchers to know if an energy drink gives people energy? …………
