题目内容

A 15-year-old student who invented a flashlight getting power from the holder's body heat is going home today from California with a big prize and a chance to do further research.

Ann Makosinski was the only Canadian among the four winners at Google's international science competition. Thousands of young scientists from around the world took part in the competition.

Winning the science and technology competition was "a surprise". Ann said, "I think it will have a great influence on my future."

Ann thanked her family for encouraging her interest in science and said that her first toy was a box of transistors(晶体管).

The ideas for the invention came from seeing unwanted batteries and her friend's experience. When Ann visited a friend in the Philippines, she saw the friend couldn't study when it became dark because there was no electricity or light. She saw the need for a flashlight that has no batteries - Hollow Flashlight.

In her project, Ann wrote "I made two flashlights that do not use any batteries or harmful materials. They do not create any noise and will always work. The flashlight needs at least a 5℃ temperature difference between the holder's body and the environment around to produce light."

A video of Ann explaining how she created the flashlight has been watched more than 1.4 million times on the Internet.

Though Ann was successful, she has not made a decision about her career path. Ann hope that she can find a way to join her love of film and science together.

The four winners were chosen from 15 final competitors from eight countries. The competition attracted thousands of students in 120 countries.

C. conclusion D. discussion

3. Paragraph 5 mainly tells us ________.

A. what Ann saw in the Philippines

B. why Ann invented Hollow Flashlight

C. how Ann's family encouraged her interest

D. what prize Ann got for Hollow Flashlight

4.According to the passage, we learn ________.

A. easy to win the international science competition

B. Hollow Flashlight is safe, noiseless and can save energy

C. Ann has made a decision to be a scientist in the future

D. few people are interested in how Ann created the flashlight

1.C

2.A

3.B

4.B

【解析】

1.1】从文章主题把握。通过阅读全文可知Ann的发明。可知 C technology “科技”正确。 travel “旅游”;culture “文化”;advertisement “广告”。

2.2】段落概括题。第一段是介绍了一个发明了靠自身的能量发电的手电筒的15岁的学生今天正从California回家的途中,她不仅获了大奖还得到了进一步做研究的机会。可见 A introduction “介绍” 正确。warning“警告” conclusion “结论” discussion“讨论”。

3.3】段落概括题。由本段第一句The ideas for the invention came from seeing unwanted batteries and her friend's experience。可知是指发明的想法来自看见废电池和她朋友的经历。因此B why Ann invented Hollow Flashlight(为什么Ann 发明中空手电筒)正确。

4.4】细节理解题。从The four winners were chosen from 15 final competitors from eight countries. The competition attracted thousands of students in 120 countries.可知获奖很难,所以A 错误;由Though Ann was successful, she has not made a decision about her career path.可知C错误;由A video of Ann explaining how she created the flashlight has been watched more than 1.4 million times on the Internet.可知Ann发明视频的点击率很高,可知D 错误。

考点:新闻报道类文章。

Do you want to know how and why a fall leaf changes color? We first have to understand what leaves are and what they do.

Leaves are the world’s food factories. Plants take water from the ground through their roots and take CO2 from the air. Plants use sunlight to turn water and CO2 into glucose(葡萄糖), a kind of sugar. Plants use it as food for energy and growing.

A chemical called “chlorophyll” in the leaves gives plants their green colour. As summer ends and autumn comes, the days get shorter and shorter, and trees “know” to begin getting ready for winter.

During winter, there is not enough sunlight or water. Trees rest during this time and live on the food they store during the summer. They begin to shut down their food-making factories. As the green chlorophyll disappears from the leaves, we begin to see yellow and orange leaves.

The bright reds and purples we see in leaves are made mostly in autumn. In some trees, like maples, sunlight and the cool nights of autumn turn the glucose in the leaves into a red colour. And we can enjoy the beautiful red leaves during autumn.

1.Which should be in the box?

A. air B. sugar C. water D. wind

A.叶绿素 B. 脂肪 C.蛋白质 D.淀粉

3.The leaves turn yellow because they are short of(缺少) __________.

B. During winter trees live on the food they store in summer.

C. During winter some of yellow and orange colors are still in the leaves.

B. there are all kinds of plants on the earth

C. not all the colors of the leaves are from chlorophyll
