It is easier to float in the ocean than it is to float in a swimming pool. Do you know why?
Ocean water is full of salt— and salt water can hold up more weight than fresh water. See for yourself!
You Will Need:
● 3 cups of warm water
● Measuring cup
● Wide-mouthed jar
● Salt
● Spoon
● Raw potato
You Will Do:
1. Pour 1.5 cups of warm water into the jar.
2. Add 1/3 cup of salt.
3. Stir(搅拌) until the salt is completely dissolved.
4. Add another 1.5 cups of water. Pour it slowly over the back of the spoon into the jar so that the two liquid will not mix together.
5. Gently place the potato into the jar. Do not drop it.
What Will Happen:
The potato will sink— but only halfway!
Why?
Salt water is heavier than fresh water, so it will stay on the bottom. The fresh water will remain on top.
The potato is heavier than the fresh water, but it is lighter than the salt water. That is why the potato will sink halfway down.
1.In which step of the experiment do you add the salt?
A. Step 1. B. Step 2.
C. Step 3. D. Step 4.
2.In Step 4 of the experiment, why do you pour the water over the spoon “slowly”?

Comera is the only place in the world which has a whistle language. We do not know how and why it began because we do not know the complete history of the island. But we can certainly imagine the reasons for the beginning of the whistle language. There are many deep valleys on the island. A person on one side of valley can not easily shout to a person on the other side. But he can whistle and be heard from four miles away, and the record is seven miles. The people who live on the island usually have good teeth, and this helps them to whistle well. They must also have good ears so that they can hear other whistlers.
We can understand why the whistle language continues. It is very useful on the island, and quite easy to learn. When somebody is hurt or ill, the whistle language takes the place of telephone. If the sick person is a long way from the town, boys and men pass the news from one to another. A boy guarding cattle on a hillside whistles to a man fishing from his boat. The last one is able to describe the trouble fully and exactly to the doctor in town. People help each other in the same way when a car breaks or a cow is lost.
The whistle language is hundreds of years old, and probably it will continue to live for hundreds of years more. Radio and TV often kill the special ways of speaking in the different parts of a country. But on Comera you are nobody if you cannot whistle. Perhaps soon after TV arrives on the island, the people there will be whistling the news and other facts and opinions.
49. If a person on Comera island is ill, .
A. others will phone the doctor in town
B. whistle language will pass the news to the doctor

50. From the passage we know radio and TV at that time.
A. killed the special way of speaking
B. whistled all the news and opinions

D. did not appear on Comera island yet
51. Comera island is special in that .
A. it attracts visitors every year
B. no visitors have ever been there
C. people there have special ears to hear whistles
D. people there use the whistle language to communicate with each other
52. Which of the following is not true according to the passage?
A. It is not easy for a person to live on Comera island if he cannot whistle.
B. The whistle language can only be found in Comera.
C. The whistle language has been used for hundreds of years on the island, but will not be used any longer.
D. The record shows that one best whistler can be heard by others seven miles away.
