    A new report says plastics are responsible for $13 billion in damage to the oceans and the undersea environment. The findings were announced recently at a United Nations conference．{#blank#}1{#/blank#}.

    Plastic thrown away carelessly makes its way into rivers and other waterways.{#blank#}2{#/blank#}. After a while, it collects in the sea. And plastic never goes away. Plastic is not biodegradable—destroyed by bacteria or natural processes. Instead, it just breaks up into smaller pieces over time. The oceans contain a lot of chemicals and other pollutants(污染物).{#blank#}3{#/blank#}.That means harmful material may get into our food supply.

    {#blank#}4{#/blank#}. Human beings cause pollution and they can take steps to stop it. They can use fewer single use product containers and throw plastics away correctly. Plastic recycling programs also works—where old bottles and other plastics are collected, broken down and used to make new products. We could reuse bottles in our households many times if we wish to, rather than end it after the first use. We could, when we get rid of that plastic, recycle it and reuse it, which replaces the need for raw materials.

    The report also calls on companies to improve methods for using plastics.{#blank#}5{#/blank#}. And it calls for information about the way plastic is thrown out or removed from use. By putting a new value on plastic, industry has a special reason to clean up the environment.

    But all of the companies must join to deal with the problem.

A. Then, fish may eat the plastics.

B. But people can make a big difference.

C. Plastics should be gathered together and reused.

D. It is convenient to use plastic bags in everyday life.

E. It asks for them to better measure and control plastic use.

F. The plastic eventually reaches coastal areas and ocean waters.

G. The report tells about harm to sea life and what might be done to improve the situation.

    Fun doesn't have to be expensive

    Everyone likes to have fun, but not everyone has much money to upend. Here are some free or cheap ways to enjoy yourself.

Get outside

    Going outside in good weather can be n lot of fun, especially if you go with a friend{#blank#}1{#/blank#} If you live in a city, you can go window-shopping. Or you can explore an old part of town and admire the building.

Try a hobby

    While you're out. take pictures of things you find. Planning and taking pictures can make you aware of the beauty all around you. Photographic equipment can be expensive, but it doesn't have to be. You probably already own a camera or a cell phone that can take pictures. Other creative hobbies can also be done with basic materials.

{#blank#}2{#/blank#}

Find an event

    Libraries often hold free public events.{#blank#}3{#/blank#} And while you're there, borrow a book or movie for free. Museums and universities also hold free events.

    If you can't find a free event, you can volunteer at an event that requires tickets. People who organize concerts and plays need help.{#blank#}4{#/blank#} Sometimes they reward volunteers with free tickets.

Meet a friend

    Relationships are often the best things in life{#blank#}5{#/blank#} Invite a friend for a walk, an event or a time working on your hobby. Hosting doesn't have to be difficult. If your friend comes in the afternoon, you don't have to serve a meal. You can sit and talk, play board games or card games or watch a movie.

A. A friend in need is a friend indeed.

B. Stop by one to find out what's going on.

F. You could set up or take down chairs or greet visitors.

G. Drawing and writing require nothing more than a pencil and paper.

    How to keep healthy? It's easy for us to catch a cold in winter and spring because the weather changes a lot in spring and it is too cold in winter. But if we take care in our life, all of us can keep healthy without any cold.

    {#blank#}1{#/blank#}This will stop germs passing from one person to another. When you finish your work or before you eat, you'd better wash your hands.

    {#blank#}2{#/blank#}Use a tissue, and then throw it into dustbins at once. When others around you are coughing, I advise you to turn your head away from the people so that their viruses won't reach you.

    Get more fresh air. Germs like staying around in dry and warm rooms. {#blank#}3{#/blank#} Don't stay too long in the places with too many people.

    If flu is going round house or school, you should try to stay away from those who are ill. {#blank#}4{#/blank#}

    Boil your toothbrush for about a minute. This kills germs.{#blank#}5{#/blank#} If you have used the toothbrush for three months or so, throw it away and buy a new one.

A.     Have a shower everyday.

B.     Wash your hands often.

C.     Don't use your hands when coughing.

D.    Don't go out often when you are coughing.

E.     Besides, don't use the same toothbrush too long.

F.     In this way, you won't be infected by these people.

G.    So you'd better stay in the places with more fresh air.

    Have you ever wondered how the trainers at Sea World get the 19,000-pound whale to jump 22 feet out of water and perform tricks? They get that whale to go over a rope farther out of the water than most of us can imagine. {#blank#}1{#/blank#}.

So how do the trainers at Sea World do it? The first thing they do is reinforce(强化) the behavior that they want repeated — in this case, to get the whale to go over the rope.{#blank#}2{#/blank#}, in a position where the whale can't help but do what's expected of it. Every time the whale goes over the rope, it's given positive reinforcement and gets fed with fish. But what happened when the whale goes under the rope? Nothing — no criticism, no warning and no feedback. {#blank#}3{#/blank#}.

    Positive reinforcement is the key of that simple principle that produces such splendid results. And as the whale begins to go over the rope more often than under, the trainers begin to raise the rope. It must be raised slowly enough so that the whale doesn't starve.

    {#blank#}4{#/blank#}. Make a big deal out of the good and little stuff that we want consistently. Secondly, under-criticize. People know they need help when they mess up. {#blank#}5{#/blank#}, people will not forget the event and usually will not repeat it.

    So we need to set up the circumstances so that people can't fail. Over-celebrate, under-criticize…and know how far to raise the rope.

A. This is a great challenge

B. And the whale stays right where it is

C. If we figure out a way to motivate the whale

D. They start with the rope below the surface of the water

E. If we under-criticize, punish and discipline less than expected

F. Whales are taught that their negative behavior won't be acknowledged

G. The simple lesson to be learned from the whale trainers is to over-celebrate

    Many facts suggest that children are overweight and the situation is getting worse, according to the doctors. {#blank#}1{#/blank#}.

    Some people blame the fact that we are surrounded by shops selling unhealthy, fatty foods, such as fried chicken and ice cream at low prices. {#blank#}2{#/blank#}, then probably children would buy less take-away food.

    {#blank#}3{#/blank#}. I agree with this, because good eating habits begin early in life, long before children start to visit fast food shops. If parents often give their children fried chicken and chocolate rather than healthy food, they will go for sweet and salty foods, and children will find it hard to get rid of the habit.

    There is a third reason for this situation. Children these days take very little exercise. They do not walk to school. When they get home, they sit in front of the television or their computers and play computer games. {#blank#}4{#/blank#}. What they need is to go outside and play active games or sports.

    The above are the main reasons for this problem. {#blank#}5{#/blank#}, as well as forcing them away from fast food shops and bad eating habits.

A. There is another argument that blames parents for allowing their children to become overweight

B. Adults are becoming fatter and unhealthier too

C. If there were fewer of these restaurants

D. So we have to encourage young people to be more active

E. Not only is this an unhealthy pastime (消遣), it also gives them time to eat more unhealthy food

F. I feel there are a number of reasons for this

G. It's a good idea to allow children to eat what they choose
