Pollution inside homes and other buildings kills more than 4 million people each year. Many people die as a result of breathing smoke or from cooking over wood-powered or coal-powered stoves.
One way to reduce the number of deaths is through cooking equipment powered by the sun. Crosby Menzies, a solar power expert in a South African company, described his latest solar cooker called the “Sol-4”. “It is four square meters of mirrors, six to eight meters in length. It is quite a large cooker.”
The “Sol-4” works by reflecting(反射) light from the sun off large mirrors. The mirrors direct the light at a cooking pan. Then the light heats the pan with solar energy. Within two minutes, the pan is hot enough to cook sausages and onions. In just four minutes, water can be boiled. That is as fast as cooking with natural gas or electricity.
The cooker is also much “friendlier” than other models because people do not have to stand in the sun to use it. And people can prepare meals without having to collect firewood or spend money on coal. Such individuals would be less likely to have breathing illnesses from harmful smoke.
At present, the cooker only works when the sun is shining. But engineers are working on a way to make it work without sunlight.
Each cooker costs about $2,000, which is a large amount of money for most Africans. To solve that problem, Crosby Menzies has created a non-governmental organization called Solar Cookers for Africa. It plans to raise money through donations to provide poor people with solar cooking equipment.
1.The passage is mainly about ________.
A. solar cookers B. smoke pollution
C. solar power experts D. breathing illness
2.The “sol-4” is mainly used to ________.
A. shorten the time of cooking
B. reduce the cost of making cookers
C. raise money through donations to help African people
D. reduce the number of deaths caused by harmful smoke
3.The underlined word “individuals” in Paragraph 4 most probably means “________”.
A. cookers B. mirrors C. people D. experts
4.Which of the following about the “sol-4” is TRUE?
A. It is six to eight square meters of mirrors.
B. It can work in any weather condition now.
C. It can also heat the pan by lighting firewood.
D. It is more environment-friendly than other cookers.
5.What can we infer from the text?
A. The “sol-4” will be designed in a smaller size.
B. More Africans can use the solar cookers in the future.
C. The “sol-4” is the first product of the South African company.
D. The African government will provide poor people with solar cookers.

Pregnancy(妊娠) and childbirth kill more than 536,000 women a year. More than half of the cases happened in Africa, according to the World Health Organization. In fact, most of the deaths are preventable with basic medical care.
The five leading causes are bleeding, infection, high blood pressure, longtime labor and bad abortions (流产). Mothers' deaths from such causes were largely reduced nearly a century ago in developed countries.
Experts say that what kill many women are “the three delays”— the woman's delay in deciding to go to the hospital, the time she loses traveling there and the hospital's delay in starting treatment. Only about 15 percent of births have dangerous complications(并发症)．
Women lack education and information about birth control. Husbands and inlaws, may decide where a woman gives birth and insist that she stay at home to save money. However, there is no single solution to a problem with so many factors—shortages of doctors, nurses, drugs, equipment, roads and transportation—though hospital officials are trying many things now.
One stopgap measure to solve the problem for the present has been to train assistant medical officers, to perform certain operations. Some African countries are now struggling to train more assistants and midwives (接生婆) , and provide places for pregnant women to stay near hospitals.
But there is a long way to go. Only 20 percent of women in the continent give birth at the hospital. More than 50 percent stay at home to give birth, and the rest go to local clinics that cannot handle emergencies.
1.Which is not included in the five leading causes of women's deaths during pregnancy and childbirth?
A. Infection. B. High blood pressure.
C. Traveling long distances. D. Bleeding.
2.The underlined word “stopgap” probably means “________ ”in the passage.
A. final B. temporary C. effective D. instant
3.What can we learn from this passage?
A. The governments of African countries have to take more effective measures to save pregnant women.
B. Developed countries should help African countries reduce mothers'deaths.
C. The husbands in poor countries should take responsibility for their wives'deaths.
D. Most problems that cause women's deaths during pregnancy and childbirth can be treated or prevented.
4.What is the author's attitude towards the future of preventing women's deaths during pregnancy and childbirth?
A. Positive. B. Negative. C. Objective. D. Subjective.

Reports tell us that Americans work more and vacation less than people in other major industrial countries. Still，millions of Americans do try to get away from home for a week or two in the summer months. Some might even have the time and money to spend longer on vacation.
For example， many retired Americans can be found driving around the United States in big recreational vehicles，known as R. V. ’s. These serve as a home away from home. In fact，it might even be their only home as they see the country.
Some American families get in their cars and drive to historic places like Colonial Williamsburg in Virginia. There，they can experience what life was like for early Americans. If that is not exciting enough， also in Williamsburg is a water park and an amusement park with rides.
Other Americans visit national parks like Yellowstone or Yosemite out in the West. They want to spend time with nature. Or they take their vacation by a lake or the ocean. They might swim or fish. But many just want to sit and enjoy the feeling of doing nothing，except maybe read a book.
Some families fly to other countries on vacation. Or they go on a cruise ship(大型游轮）and stop in different ports. Cruise ships are like floating cities.
