Why should we learn to swim?

Firstly, swimming is a good exercise for our health. Indeed doctors say it is the best exercise, because in swimming all the muscles of the body are used.

Secondly, swimming gives great pleasure. How nice it is, on a hot dusty day in summer, to take off one’s clothes and dive into the cool water of a rive or the sea, and to swim and float until one feels enough.

Thirdly, swimming may sometimes mean all the different between life and death, we never know when we may be in danger from water. We got on a voyage, and the ship in wrecked; we go for a pleasure sail on a lake and the boat turns over; we slip as we are walking along the bank of a river, and half in the water. If we can swim, we have chance for saving our own lives, but if we cannot swim, we are pretty certain to be drowned. So for our own safety, we should learn to swim.

Lastly, if we can swim, we may be able to save other people from drowning. How sad it is to see a friend drowning before our eyes while we cannot help just because we cannot swim.

(   )4.Who says that swimming is the best exercise?  _________.

A. Farmers  B. Dentists    C. Fishermen        D. Doctors

(   )5.When swimming, ________.

Because earthquakes happen without warning, it’s important to take steps now to prepare. Because you don’t know where you will be when an earthquake happens, prepare some supplies for your home, workplace, and car.
1. Water.
A person needs at least 1/2 gallon of water daily just for drinking. Store at least 1 gallon of water per person per day and be prepared for a 72-hour period. It is suggested that you buy bottled water. Keep bottled water in its original container and do not open it until you need to use it. Also, do check the “use by” date.
2. Food.
It’s always a practical idea to keep a supply of non-perishable(不易腐爛的) food on hand. Have an enough supply of canned food, powdered milk, dried fruits, non-salted nuts and canned juices for at least 72 hours.
3. Flashlights(手電筒) and spare batteries.
Keep a flashlight beside your bed, at your place of work, and in your car. Do not use matches or candles after an earthquake until you are sure that no gas leaks.
Prepare a battery-powered radio and spare batteries. Most telephones will be out of order, so radios will be your best source of information.
4. Clothes.
If you live in a cold place, you must think about warmth. You might not have heat after an earthquake. Think about your clothing and bedding supplies.
【小題1】 Why should people prepare themselves for an earthquake?
A.Because earthquakes can be known before they happen.
B.Because earthquakes take place without warning.
C.Because earthquakes usually take place in the neighborhood.
D.Because it’s people’s daily work to prepare the earthquakes.
【小題2】 About the prepared water, which description is RIGHT?
A.A person should prepare 0.5 gallon of water for one day.
B.You’d better use your own containers to keep water.
C.You’d better open the bottled water when you buy it.
D.You shouldn’t open the bottled water until you need it.
【小題3】 You should prepare all of the following except ______.
A.powdered milkB.fresh vegetables
C.dried fruitsD.canned juices
【小題4】According to the article we know that ______.
A.we need to prepare some supplies only at home
B.a(chǎn) telephone is the most important prepared thing

There are nearly 400 different types of sharks, but only about 30 types have even been reported as attacking human beings.
The chances of being attacked by a shark are very small compared to other dangers. Many more people drown(溺死)in the ocean every year than are bitten by sharks. The low number of attacks that happen every year proves that sharks do not feed on humans if they have the choice. There are three types of shark attacks. The main one is known as a ‘hit and run’. The shark attacks because it thinks you are a fish, but when it tastes a human it decides not to eat you. The second type is called a ‘bump and bite’. The shark bumps you to find out if you are fit to be eaten and then bites you if it thinks you are. The third type is called a ‘sneak’. When attacking in this way, the shark waits for you to swim by and attacks you suddenly. The latter(后者的)two types of attack are more likely to be deadly for humans.
However, your chances of being attacked by a shark can be reduced if you follow the advice below.
Do not swim in the dark. Sharks can still see you but you cannot see them.
Do not swim if you are cut or if you have a fresh wound. Sharks can smell blood over a long distance.
Do not wear bright clothing or jewellery because sharks are attracted to colours and shiny objects.
Try and stay in groups, as sharks usually avoid large numbers of people.
Don’t be frightened(受驚嚇)by sharks as there is 30 times greater chance of being hit by lightning than being attacked by a shark.
【小題1】Are there only 30 types of sharks in the world?
【小題2】Are the chances of being attacked by a shark small or big compared to other dangers?
【小題3】What are the two deadly shark attacks called?
【小題4】Why should you try and stay in groups to avoid the shark attack?
【小題5】What does the writer mainly tell us in the passage?
