How to get rid of waste is a great problem for the world today. Waste must be treated 16 it does not become a danger to life.   17 , in some countries, waste from factories is still poured straight into rivers. People who use the water from one of these rivers often get   18 . The water  may become so polluted that it   19  all the fish in the river. When these rivers finally reaches the   20 , it pollutes the ocean.
In many countries with   21 , human waste is piped directly into the sea without being dealt with. This is not   22 . Although the sea itself can break up the waste, beaches   23  become polluted.   24  scientists suggest people take the waste far out to sea in ships where the wind and waves break it down.
In 1989 an international law was passed to   25  people putting waste into the sea. It is now against the   26  to put anything into the sea nearby. Such rubbish as plastics may not be thrown   27  the sea anywhere. Other waste may be put into the sea, either 19 or more than 40 kilometers from land,   28  the nature of the materials.
The   29  of dealing with waste has become so great that several international organizations have been   30  to protect the world and control pollution.

Waste to Energy—JUST BURN IT!
WHY BURN WASTE?
Waste-to-energy plants generate (产生) enough electricity to supply 2.4 million households in the US. But, providing electricity is not the major advantage of waste-to-energy plants. In fact, it costs more to generate electricity at a waste-to-energy plant than it does at a coal, nuclear, or hydropower plant. 
The major advantage of burning waste is that it considerably reduces the amount of trash going to landfills. The average American produces more than 1,600 pounds of waste a year. If all this waste were landfilled, it would take more than two cubic yards of landfill space. That’s the volume of a box three feet long, three feet wide, and six feet high. If that waste were burned, the ashes would fit into a box three feet long, three feet wide, but only nine inches high!
Some communities in the Northeast may be running out of land for new landfills. And, since most people don’t want landfills in their backyards, it has become more difficult to obtain permits to build new landfills. Taking the country as a whole, the United States has plenty of open space, of course, but it is expensive to transport garbage a long distance to put it into a landfill.
TO BURN OR NOT TO BURN?
Some people are concerned that burning garbage may harm the environment. Like coal plants, waste-to-energy plants produce air pollution when the fuel is burned to produce steam or electricity. Burning garbage releases the chemicals and substances found in the waste. Some chemicals can be a threat to people, the environment, or both, if they are not properly controlled.
Some critics of waste-to-energy plants are afraid that burning waste will hamper (妨碍,阻碍) recycling programs. If everyone sends their trash to a waste-to-energy plant, they say, there will be little motive to recycle. Several states have considered or are considering banning waste-to-energy plants unless recycling programs are in place. Massachusetts, New Jersey, and New York City have delayed new waste-to-energy plants, hoping to increase the level of recycling first.
So, what’s the real story? Can recycling and burning waste coexist? At first glance, recycling and waste-to-energy seem to be at odds (不一致), but they can actually complement (弥补) each other. That’s because it makes good sense to recycle some materials, and better sense to burn others.
Let’s look at aluminum, for example. Aluminum mineral is so expensive to mine that recycling aluminum more than pays for itself. Burning it produces no energy. So clearly, aluminum is valuable to recycle and not useful to burn.  
Paper, on the other hand, can either be burned or recycled—it all depends on the price the used paper will bring.
Plastics are another matter. Because plastics are made from petroleum and natural gas, they are excellent sources of energy for waste-to-energy plants. This is especially true since plastics are not as easy to recycle as steel, aluminum, or paper. Plastics almost always have to be hand sorted and making a product from recycled plastics may cost more than making it from new materials. 
To burn or not to burn is not really the question. We should use both recycling and waste-to-energy as alternatives to landfilling.

Plastic is everywhere because plastic is an extremely useful material. It is cheap, strong and lightweight. What’s more, it can take on nearly any form or shape, from soft and stretchy (有弹性的) to hard and glasslike.

Plastic, however, is far from perfect. It may even be bad for us. Studies now suggest that poisonous chemicals can get out of some types of plastic, get into our bodies, and cause a variety of health problems, including cancer, birth defects and attention deficit hyperactivity disorder (注意缺陷障碍).

Two types of chemicals in particular have raised special concern lately. They are called phthalates (邻苯二甲酸盐) and Bisphenol-A (二酚基丙烷), BPA for short. Not all plastic products contain them. But the ones that do are surrounded by controversy (争议). That’s because experts disagree on how dangerous these chemicals are.

Plastic is a single word, but plastic isn’t just one thing. What all plastics share in common are plasticizers -- special chemicals that allow the material to be changed into nearly any shape or texture. Plasticizers (塑化剂) are added to plastic during the manufacturing process.

Phthalates and BPA are two types of plasticizers that work in different ways. Phthalates add softness to things like shampoo bottles, raincoats and rubber. They are also used in perfumes and makeup. BPA, on the other hand, gives a hard, clear, almost glasslike feel to products such as infant bottles. BPA also appears in food and soda cans, DVDs and other unexpected places.

How do these chemicals get into us? When plastic is heated in the microwave or dishwasher, chewed on or scratched, the chemicals can seep (渗透) out of the plastic. Even though we can’t see them, we eat them, drink them and breathe them in.

Scientists and parents are especially worried about young children, who tend to chew on everything, including plastic. Dozens of countries, including the European Union, Japan, Canada and Mexico have already banned phthalates from products made for children younger than three. California and Washington have done the same. And a number of other states are considering similar rules. As for BPA, Canada became the first country to ban the chemical from baby bottles. A dozen states are considering it.

1.What can we know about the plastic from the first paragraph?

A. Its characters and effects.                   B. Its wide use and bad points.

C. Its importance and chemicals.               D. Its popularity and advantages.

2.Which of the following products contains BPA?

A. A soft plastic cup.                           B. A pencil eraser.

C. A baby milk bottle.                            D. A new perfume.

3.Phthalates and BPA can get into us __________.

A. through mouth or nose                          B. through blood transfusion

C. by feeling plastic products                  D. by heating in the microwave

4. What is the passage mainly about?

A. A new ban on plastic products.             B. Problems caused by the plastic. 

C. Good points of the plastic.            D. The use of plasticizers.

I’m a pig, and my son is a rabbit. I have snakes for daughters, and my wife, believe it or not, is a dragon! Do I live in a zoo? No, of course not! I am talking about Chinese zodiac signs(十二生肖). Depending on the year of your birth, each person has an animal for a sign. That’s why I am a pig and my wife is a dragon. If you, like me, were born in the year of the pig, then you are brave, thoughtful and loyal. The year of the pig is filled with good fortune.

   Now let’s take a closer look at this interesting animal.

   Pigs were first raised by man about 9,000 years ago, and are still a very common farm animal in many parts of the world. We don’t just use pigs for their meat — almost every part of the animal is used. The hair is used for artists’ brushes. The fat is used to make floor wax, rubber and plastics.

    Pigs have also been important in the world of entertainment. In 1995 the film ‘Babe’ starred a loveable talking pig as its main character. The film won an Oscar and was nominated (提名)for 6 more. In England you can even go to watch pig racing. A farmer, Rob Shepherd, has been raising money for charity by holding pig races on his farm. The events have been very successful. People don’t just want to eat pigs, it seems!

    Pigs also play an important role in the English language. For example, if someone says that he will travel to the sun one day, you can say “pigs might fly!” to him. Hungry? Well then, you can “pig out” and eat lots of food. And what if someone rescues you? Well, you can say that they “saved your bacon”.

1. The writer wrote the first paragraph in a ______ tone.

  A. sad      B. confused        C. serious     D. humorous

2. We may know from the passage that ______.

  A. people in England like pigs more than other animals

  B. pigs are more useful than ordinary people imagine

  C. pigs are the first animals raised by man

  D. more people don’t want to eat pigs now

3.The underlined sentence “pigs might fly!” in the fifth paragraph means “______”.

  A. What you have just said is impossible

  B. Pigs are great animals

  C. I don’t understand your words

  D. I can’t agree with you more

4.Which diagram shows the structure(结构) of the passage?

         

     A         B        C          D

You may never connect the words “good” and “eco-friendly”with plastic.It’s time to do a rethink on that as we say hello to hemp(大麻)plastic.Traditionally,plastics have been made from petrochemicals,which are mainly poisonous.Plants,on the other hand,are also a source of cellulose(纤维素),which can be used to make biodegradable (生物所能分解的)plastic.As hemp happens to be one of the richest sources of cellulose,it is only natural that scientists will support its use,considering its ecological benefits.
Hemp plastic is biodegradable and recyclable.If you thought being eco-friendly reduced its solidity,you couldn’t be more wrong.The hard level of hemp plastic can match that of regular plastic.Hemp plastic is resistant to heat;however,the most outstanding feature of a few varieties of hemp plastic is that they are flame resistant too.Finally,if Henry Ford could imagine creating a car with this material,we can perhaps believe that it indeed is“ten times stronger than steel”.
It is a pity that with so many useful qualities,we don’t see hemp plastic being used in our everyday life,the way it ought to be.Hemp plastic can easily take the place of the exiting plastic in products like cell phone chargers(充电器),laptop covers,etc.Currently,hemp plastic is being used to produce audio(音响设备),video,toys,automobile parts and packaging materials.
Hemp fiber is one of the strongest natural fibers known to us.As scientists keep looking for ways to solve the ecological damage that traditional plastics have caused,here is a material that can be produced to be 100% biodegradable.Hemp plastic is known to be several times durable as compared to polypropylene(聚丙烯)plastic,and it comes without all the health and safety threats,It really has long useful life.
Plastics keep reminding us of the damage that we have done to our planet,all under the excuse of convenience.As hemp products have become a new choice into our daily life,Please take a green plan now and make your effort to protect the environment.
