根据短文理解,选择正确答案。

    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 (把……对准) 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.

 C. Read the passage and fill in the blanks with proper words. 

Every English learner wants to speak English and have a good accent, So what is the hottest accent in Britain now?

In English , RP means Received Pronunciation or Standard Pronunciation. It is what we learn at school. However, u{#blank#}1{#/blank#} Mandarin in Chinese, RP English is not popular on TV or radio in Britain though it used to be the most prestigious(有声望的)accent. It is r{#blank#}2{#/blank#} to find someone who really speaks RP English now . Probably the Queen is one of the f{#blank#}3{#/blank#} people who speak that way. 

In fact, RP English is not standard English in Britain. It's not what most people speak e{#blank#}4{#/blank#} . As we know, there was a lot of accents and dialects. F{#blank#}5{#/blank#} the way people speak English , you can understand their social, educational and geographical background. British people are so proud of the class that they are from. If they are working class, they are proud of b{#blank#}6{#/blank#} working class. And they don't want to belong to a different class. To them, the most important thing is that they can speak clearly and fluently, They love their accents. 

The h{#blank#}7{#/blank#} English accent is :don't copy other people's accent, but sometimes adjust your own accent according to different situations.

Museums are active centers of learning. In a science museum, people can learn about nature and technology as well as physics and chemistry. Visiting museums is a good choice to spend a holiday for people of all ages. But there're some rules when visiting museums. Take an art museum, for example.

Keep quiet. You can talk, but keep the voice down and be polite to those around you. You should turn off your phone or put it on silent. Sounds from your phone may disturb (打扰) others. If a call must be made, you should go outside to make it. 

Ask before taking photos. Some museums welcome visitors to photograph or videotape works of art. However, please be careful with the sign "no photography" which means taking photos is not allowed for that work or exhibition. If you take photos without permission, you will be in trouble. Maybe you will be punished. 

Do not touch works of art! Your touch may not seem like much, but even the slightest (最轻的) touch can damage the surface of a painting, discolor stone, and even rust metal. Keep a safe distance between you and each work of art. This helps to avoid accidental touching.

Never bring food or drinks into the museum. It's no good eating or drinking there. The art in the museum will provide plenty of food for thought as well as a dinner for the eyes!

Running and pushing are not allowed in the museum. Proper museum behavior is necessary to avoid accidentally hitting or damaging works of art.

Remember: ____. If you obey them, you will surely enjoy yourself in the museum.
