You can't always predict a heavy rain or remember your umbrella. But designer Mikhail Belyaev doesn't think that forget?ting to check the weather forecast before heading out should result in you getting wet. That's why he created Lampbrella,a lamp post with its own rainsensing umbrella.

The designer says he came up with the idea after watching people get wet on streets in Russia. "Once,I was driving on a central Saint Petersburg street and saw the street lamps lighting up people trying to hide from the rain. I thought it would be appropriate to have a canopy (伞篷) buiit into a street lamp," he said.

The Lampbrella is a standardlooking street lamp fit?ted with an umbrella canopy. It has a builtin electric mo?tor which can open or close the umbrella on demand. Sen?sors (传感器) then ensure that the umbrella offers pedes?trians shelter whenever it starts raining.

In addition to the rain sensor,there's also a 360° mo?tion sensor on the fibreglass street lamp which detects whether anyone is using the Lampbrella. After three mi?nutes of not being used the canopy is closed.

According to the designer,the Lampbrella would move at a relatively low speed,so as not to cause harm to the pedestrians. Besides,it would be grounded to protect from possible lightning strikes. Each Lampbrella would offer enough shelter for several people. Being installed (安装) at 2metres off the ground* it would only be a danger for the tallest of pedestrians.

While there are no plans to take the Lampbrella into production,Belyaev says he recently introduced his crea?tion to one Moscow Department,and insists his creation should be installed on any street where a lot of people walk but there are no canopies to provide shelter.

15. What do we know from Belyaev's words in Paragraph 2?

A. His creation was inspired by an experience.

B. It rains a lot in the city of Saint Petersburg.

C. Street lamps are protected by canopies.

D. He enjoyed taking walks in the rain.

16. Which of the following shows how the Lampbrella works?

A. motor—canopy—sensors

B. sensors—motor—canopy

C. motor—sensors—canopy

D. canopy—motor—sensors 17. What does Paragraph 5 mainly tell us about the Lampbrella?

A. Its moving speed.

B. Its appearance.

C. Its installation.

D. Its safety.

18. What can be inferred from the last paragraph?

A. The designer will open a company to promote his product.

B. The Lampbrella could be put into immediate pro?duction.

C. The designer is confident that his creation is prac?tical.

D. The Lampbrella would be put on show in Mos?cow.

[文章大意]这是一篇说明文。文章主要介绍了设计师Mikhail Belyaev设计的Lampbrella ,它能给街道上的人们遮雨。虽然这一设计还没有被付诸实践，但是Mikhail Belyaev对自己的设计很自信。

15. A推理判断题。从第二段Mikhail Belyaev说的话"'…I was driving ... and saw the street lamps lighting up people trying to hide from the rain. I thought it would be appropri?ate to have a canopy (伞篷) built into a street lamp”―"可知，他的灵感来自他的一次生活经历。故选A.

16. B细节理解题。从第三'段的内容可知答案。Lampbrella 工作的过程是先通过传感器(sensors) ,传到发动机(mo tor) ，再到伞篷(canopy) 打开。故选B.

17. D段落大意题。从第五段的"— so as not to cause harm to the pedestrians."和"Being installed (安装) at 2 metres off the ground,it would only be a danger for the tallest of pe?destrians. "可知，该段是讲Lampbrella的安全性。

18. C推理判断题。从最后一段Mikhail Belyaev说的话可知他对自己的设计很自信。故选 C.

Cooking food over a smoky fire is found everywhere in the world. It is often difficult to. find wood for the fire. People who do not have wood must spend large amounts of money on cooking fuel. However,there is a much easier way to cook food using energy from the sun. Solar cookers,or ovens,have been used for centuries. A Swiss scientist made the first solar oven in 1767. Today,people are using solar cookers in many countries around the world. People use solar ovens to cook,food and to heat drink?ing water to kill bacteria and other harmful organisms.

There are three kinds of solar ovens. The first is a box cooker. It is designed with a special wall that shines or reflects sunlight into the box. Heat gets trapped under a piece of glass or plastic covering the top of the cooker. A box oven is effective for slow cooking of large amounts of food.

The second kind of solar oven is a panel (嵌板式) cooker. It includes several flat walls,or panels,which directly reflect the sun's light onto the food. The food is inside a separate container of plastic or glass that traps heat energy. People can build panel cookers quickly and with very few supplies. They do not cost much. In Kenya,for example,panel cookers are being manufactured for just two dollars.

The third kind of solar oven is a parabolic (拋物线的) cooker. It has rounded walls that aim sunlight directly into the bottom of the oven. Food cooks quickly in parabolic ovens. However,these cookers are hard to make. They must be reaimed often to follow the sun. Parabolic cookers can also cause burns and eye injuries if they are not used correctly.

You can make .solar ovens from boxes or heavy paper. They will not catch fire. Paper burns at 232 degrees Celsius. A solar cooker never gets that hot. Solar ovens cook food at low temperatures over long periods of time. This permits people to leave food to cook while they do other things.

To learn more about solar cooking,you can write to Solar Cookers Internation?al. The postal address is 1919 21st Street,Sacramento,California 95811-6827,USA. Or you can visit the group's Internet website. The address is www. solarcooking,org.

1. When was the first solar cooker invented?

A. Development Report. B. Agricultural Report. C. Health Report. D. Education Report.

3. Which of the following is TRUE?

A. The first solar oven was made by a Swiss soldier.

B. Parabolic cookers can be dangerous sometimes.

C. Solar ovens often get hotter than 232° C.

D. It is more expensive to cook with a solar oven than on fire.

4. Which of the following could be the best title of the passage?

A. Different ways of cooking B. The history of the solar cookers
