【題目】Could cities that float (漂浮) on the sea solve the problems caused by floods and provide food for the world?

Some scientists think so. The idea is already being tested and they believe that floating citied will provide more homes for a growing population, without having to use land needed to grow food. And they believe floating areas will allow more food to be grown, so that no one in the world is hungry.

In some places, cities that float on the sea are already being planned, A company in the Netherlands called DeltaSync thinks that sea cities will save the world, with more than one in ten people living in them.

They say sea cities solve many of the problems the world faces in the 21st century, like not having enough land , more and more people needing homes, fossil fuels (礦物燃料) running low and the increasingly serious problems caused by floods.

DeltaSync says building in the desert (沙漠) is not possible because there is no enough water and that developing ways for people to live in space is still too expensive. So they believe the answer is our oceans, which cover over two thirds of the Earth’s surface. Their plans for floating areas include using algae (海藻) to produce fuel and food.

More than a quarter of the land in the Netherlands already lies underwater and scientists there have spent years trying to find ways to deal with it. In the city of Rotterdam they already have floating homes.

Bart Roeffen from DeltaSync says: “We have plans for neighbourhoods including roads and, in the end, I believe we can build floating cities on the sea.”

A．on land B．in space

【3】What does Bart Roeffen think of his company’s future plans?

A．He doubts them.

B．He is hopeful of them.

C．He is uncertain about them.

D．He has no idea about them.

【4】What is the best title for the text?

【題目】New York — Wednesday, October fifteenth, is the first Global Hand Washing Day. Activities are planned in more than twenty countries to get millions of people in the developing world to wash their hands with soap.

Experts say people around the world wash their hands but very few use soap at so-called critical moments. These include after using the toilet, after cleaning a baby and before touching food.

Global Hand Washing Day is the idea of the Public-Private Partnership for Hand Washing with Soap. The goal, they say, is to create a culture of hand washing with soap. The organizers say all soaps are equally effective at removing disease-causing germs (病菌). They say the correct way to wash hands is to wet your hands with a small amount of water and cover them with soap. Rub it into all areas, including under the fingernails. Then, rinse well under running water. Finally, dry your hands with a clean cloth.

The Partnership says soap is important because it increases the time that people spend washing. Soap also helps to break up the dirt that holds most of the germs. And it usually leaves a pleasant smell, which increases the likelihood that people will wash again.

It also says washing with soap before eating and after using the toilet could save more lives than any medicine. It could help reduce cases of diarrhea (痢疾), which is the second leading cause of child deaths, killing more than one and a half million children a year, by almost half.

【1】The most suitable title for the text would be _____.

A. Hand Washing Brings Good Health

B. Hand Washing Gets a Day of Its Own

C. It Is Soap That Matters

D. Partnership for Hand Washing Takes Action

【2】The Partnership creates Global Hand Washing Day to _____.

A. call on people to wash hands

B. help the developing countries

C. promote the importance of soap in hand washing

D. make a culture of hand washing in the third world

【3】The following facts can explain why soap is important EXCEPT that _____.

A. soap gives people a longer hand washing time

B. soap helps to get rid of more germs off hands

C. soap attracts people to do more hand washing

D. soap gets people into the habit of washing hands

【4】According to the last paragraph, diarrhea is a disease that _____.

A. kills half of the kids in developing countries
