something about climate change. And it"s not just for the good of the planet: Tuvalu could be covered by the
sea in less than 50 years if the planet gets much hotter.
Tuvalu has no industry, burns little petrol, and creates less carbon pollution than a small town in America.
However, this tiny place is on the front line of climate change. The increase in ocean temperatures and the
rising sea level -all resulted from a warming atmosphere-are making trouble for Tuvalu.
Sea level rise is the greatest problem. With an average elevation (高度) of 6 feet above sea level, Tuvalu
doesn"t have far to go. Tuvalu"s highest elevation is 4.6 meters-15 feet-but most of it is no more than a meter
above the sea. Several times each year the regular lunar cycle of tides (潮水), riding on the ever higher sea
level, brings the Pacific waters over onto roads and into neighborhoods. Sometimes a high tide can flood roads
and run across the whole land. You can never separate the sea from the land, so some natives warned visitors,
"You"d better not run after dark, for you may fall into the sea."
B. It has little petrol to burn.
C. It will sink into the sea in the near future.
D. The climate there has changed much.
B. Tuvalu doesn"t create much carbon pollution.
C. Most of Tuvalu is no more than a meter above the sea.
D. A small town in America is on the front line of climate change.
B. Tuvalu, an Island Nation
C. Flooded Tuvalu
D. Global Warming

It makes our health better to take morning exercises. The air is never so fresh as early in the morning. Early
rising helps us in our studies. In the morning we learn more quickly and find it easy to learn something by
heart.
Early rising makes people able to plan the work for the day. We can"t work well without a good plan. Just
as the plan for the year should be made in the spring, the plan for a day should be made in the morning. Early
rising gives us enough time to get ready for our work, such as to wash our hands and eat our breakfast. So
the popular saying says, "Early to bed and early to rise makes a man healthy, wealthy and wise."
B. getting up
C. have breakfast
D. making a day"s plan
B. Because we are not busy in the morning.
C. Because air in the morning is very fresh.
D. Because we don"t need to prepare for breakfast.
B. a good reading
C. clean hands
D. a good plan
or join a gym. You just follow some habits that thin people have. Keep them, and you"ll become thin.
(1)Wake-up
When you wake up in the morning, sit up slowly without using your hands. With legs straight out, bend
(弯曲) forward until you feel sore in your back. It will burn about 10 calories (热量单位, 卡路里).
(2)Start with soup
When you have a meal, order a clear soup, and have it before having the main food. In this way, you"ll
feel fuller, so you"ll eat less when the main food comes.
(3)An apple (or more) a day
Apples are full of fiber (纤维) and water, so your stomach will want less. The study shows that people
who eat at least three apples a day lose weight.
(4)Stand up and walk around
Every time you use the mobile phone, stand up and walk around. Heavy people sit on average (平均) two
and a half hours more each day than thin people. This skill is very important as standing up and walking
around will burn 50 or more calories.
Use these skills, and you will have a big weight loss.
B. Ice cream.
C. Salad.
D. Cheese.
B. Because apples are full of fiber and water.
C. Because apples are sour.

I used to be a doctor in a children"s hospital. Sometimes I treated children who had been poisoned (中毒)
by medicines for older family members. The children didn"t know the medicine was dangerous; they just knew
it tasted sweet. Children easily opened the bottle that we now use in China.
Some days ago I talked about medicine with an American. He showed me a kind of plastic bottle. The
design was very quite simple and I"m sure our Chinese factories could produce these bottles. The top of the
bottle locks but can be opened by pressing down on it while turning. This is difficult for most young children
to do, though grown-ups can open these bottles very easily.
I"m certain that the price of making such tops would be very low. As a doctor, I"d love to see this done.
And most parents would be grateful.
Yours,

a hill. The water is muddy because it washes away soil from the hill slopes.
Sometimes soil is blown away by strong winds. When the soil is carried away by water or wind, we say
that the land is eroded (侵蚀). This is known as soil erosion.
Plants cannot grow on eroded land. There is not enough soil on eroded land to give them the things they
need. Plants need water and salts from the soil.
We can do a number of things to stop soil erosion. This is called soil conservation (保护).
One way of soil conservation on flat, open ground is to grow small plants such as grasses. Their roots
hold the soil tightly together. Another way is to plant trees around an open field. Thus soil erosion by strong
winds cannot take place. Rows of trees act as a very big wall.
Soil erosion on slopes can be stopped by cutting "steps" called terraces (梯田). Water carrying soil cannot
run straight down the slope now. It has to run down the terraces. This slows down the flow of the water.
Most of the soil in the water is left behind on the terraces.
There are some other ways of soil conservation.
B. there is no small plant on the slopes
C. it washes away soil from the slopes
D. there is too much soil on the slopes
B. there is not enough water and salts
C. there is no water
D. the land is too hard
B. to plant trees around an open field
C. to add fertilizer to the soil
D. A and B
B. two
C. more than three
D. six
the overuse of the lakes, natural climate changes and other factors (因素), these lakes are disappearing quickly.
Millions of people in Africa depend on water sources like lakes and rivers for their daily water. In other
words, they cannot live without these lakes and rivers. Recent studies by the United Nations show that this
loss of water supply is putting a great pressure on the African population.
In the 1960s, Lake Chad was nearly 83,200 square feet large. In about forty years, it has lost 95% of its
size and it has almost completely dried up. At one time, it was one of the largest lakes in the world, and was
around 960,000 square feet around 6,000 years ago.
The sizes of lakes and rivers and the amount of water have something to do with seasons naturally. But,
pollution and agriculture also play an important part in the loss of water. Many pollutants (污染物) are put into
lakes and rivers so that many lakes and rivers are seriously polluted, and the water may be poisonous (有毒的).
If something isn"t done soon about the disappearing lakes and rivers, there will not be enough water for
everyone. Then many people in Africa will face diseases and possible dehydration (脱水).
B. Africa is the largest continent on earth.
C. As climate changes, there is less and less water in Africa.
D. Now Africa has less water than before.
B. Lake Chad was a large lake
C. how quickly water is being lost in Africa
D. Lake Chad is 4,160 square feet now
B. Agriculture develops quickly.
C. The number of population in Africa will be smaller.
D. Many people will suffer from diseases.
B. To show people the results of the loss of water in Africa.
C. To call on people to solve the problem of the loss of water in Africa.
D. To tell people how to protect the lakes and rivers in Africa.
