First,have a family meeting. Plan a way to get your family members together if they can’t find each other after the disaster. Choose two places for everyone to go to if it isn’t safe to return home. The first should be near your house. You can go there in an emergency(紧急情况) like a fire. The second meeting place should be outside your neighborhood.

Next,choose a person outside your area who can help your family get in touch with each other. After a disaster, it is often easier to communicate(交流) over a long-distance(长途) call than a local one. The person can pass messages between your family members.

Then, get a family disaster kit(工具箱) ready. It should include things your family needs. It can help you survive(生存) at least for three days like bread, water, medicine and things like that. Put them in a bag so you can carry it if you leave in a hurry. When doing it, remember that different people have different needs. Include special things necessary for elderly or young members of your family.

Finally, practice your emergency plan, and update(更新) it as necessary.

You may not be able to stop disasters, but with a little planning you can be helped.

When people have a cold, a fever, or the flu, they usually go to the doctor for help, or they get some medicine from the drugstore. But many people also use home first-aid ways for common illness. The following are some simple examples.

Colds　 Lots of people eat hot chicken soup when they have a cold. They find it can make the head and the nose clear. Some people drink hot lemonade with red pepper and sugar.

Burns　 First find out how bad it is, and then put the burned area under cold running water. It’s important not to put ice on the burns.

Cuts　 Cover the cut with a clean cloth first. Then press it hard. If it’s a deep and serious cut, go to a doctor as quickly as possible.

Sore throats　 Drink some hot tea with honey. Or put pepper on slices of meat and tie them around your throat with a cloth.

Headaches　 Put an ice bag or a cold cloth on your head, or wash your face with cold water. It’s also a good idea to put your hands into hot water and let them stay there for several minutes.

根据短文内容，判断句子正（T）、误（F）。

1.Eating Chicken soup can never make the head and the nose clear when you have a cold.

Have you ever wished to have an umbrella that makes your hands free? Alan Kaufman has come up with the “Nubrella”, which means “new” + “umbrella”. It is the first truly hands-free umbrella in the world. The inventor says that it stops rain, wind and snow and can keep your head, face and hair dry.

“I never planned to invent a product. I just noticed a problem and had a new idea,” said the inventor. The idea for the invention began on one rainy day. Mr Kaufman was standing in one of his stores. He began to look at people’s umbrellas. He found that they had to try very hard to keep their umbrellas in the right place. At that moment an idea came into his mind. He ran to his desk and drew a picture. In this way, the nubrella was born.

One cool feature of the nubrella is that you don’t hold it like a normal umbrella; you wear it. The shoulder straps (肩带) of the nubrella allow people to be fully hands-free, so when walking in the rain with the nubrella, you are able to use your cell phone or drink a hot cup of coffee. Also, the nubrella will never be inverted (颠倒) in the wind. The new umbrella is far safer than traditional ones, because it has no sharp points.

1.    “Nubrella” is a kind of _____ umbrella.

A. normal            　　 B. hands-free

C. traditional            D. paper

2. --- How can you use the “Nubrella”?

--- You can _____.

A. wear the shoulder straps of the nubrella

B. put the nubrella on your head

C. use your hands to hold it up

D. carry it on your bike

3.Which of the following is not right?

A．"Nubrella" means "new" + "umbrella"．

B．The idea of the nubrella came from the rainy day．

C．Walking in the rain, you'd better take the nubrella．

D．If you go out with the nubrella, you have it in your hands.

It’s always a happy moment when you get some pocket money. But have you ever thought about how to spend your pocket money wisely? Here is some advice.

Make a list.

When you get your pocket money, don’t get too excited. We all have a lot of things that we want. But do you really need them? That’s why it is necessary to make a list before you spend money. Start with the thing you want most. You can also write down how much it costs or how important it is in your life. By doing this, you will see if it is really necessary to buy it.

Help others.

How about being more selfless and using your pocket money to help others? We all know that there are many people in the world who are in need of our help.

Save as much as you can.

There is an old saying that “Money doesn’t grow on trees.” If you spend all your pocket money right away, you’ll have no money until your next “pay day”. A wallet sometimes might not be the best place to save money because it may make it easier for you to spend your money.
