【題目】根據(jù)短文理解，選擇正確答案。
Since 2008, hunters have illegally killed more than 3000 rhinos in South Africa. The International Union for Conservation of Nature warns that rhinos may die out by 2026. People who hunt and kill illegally are called poachers. The most effective way to watch for and prevent illegal hunting is from the air. However, piloted flights are too costly. Fortunately, some Spanish college students have invented a drone (無(wú)人機(jī)) that can observe more places than a plane.
Arnau Garcia is an aeronautical (航空學(xué)的) engineering student at the Polytechnic Institute of Catalonia, in Spain. He says observers from the air have trouble finding poachers when they hide under the trees. Mr. Garcia and other students have worked with the drone manufacturer HEMAV to help find the hidden poachers. They make it by using the thermal camera, which is especially sensitive to body heat. Even when the poachers keep still, it can also keep track of them.
The drone can fly in the wind up to 55 kilometers per hour. It has an autopilot system, so it memorizes the flight path. The drone also has a microphone, a video camera and a GPS system. These permit it to report accurately where a picture is taken. After each flight, the drone can bring back detailed information about where rhinos are found, the conditions of water and plants in the area, and the positions of suspected poachers.
Experts say the drone can fly as far as 70 kilometers from the base. It means that it could quickly observe large areas for poachers. However, the same search operation would take days for human observers. Thanks to the drone, many poachers have been caught and the number of rhinos is on the increase. In addition, HEMAV has received an increasing number of orders for the drone. Even South African national park officials attempt to fill the air with drones.
（1）What do we know about the drone? _____
A.It may get lost easily in the air.
B.It can't work in the windy days.
C.It can offer detailed information.
D.It is useless when the poacher stays still.
（2）What's the best title for the text? _____
A.How to make the drone work well
B.A new way to stop illegal hunting
C.The living conditions of rhinos are worrying
D.The drone helps save rhinos in South Africa

【答案】
（1）C
（2）D
【解析】無(wú)人機(jī)幫助保護(hù)犀牛。

（1）C細(xì)節(jié)理解題。根據(jù)第三段第五句After each flight, the drone can bring back detailed information每次飛行之后，無(wú)人機(jī)能帶回詳細(xì)的信息。故選C。

（2）D主旨大意題。根據(jù)第一段第二句The International Union for Conservation of Nature warns that rhinos may die out by 2026.到2026年犀�？赡軠缃^。第六句some Spanish college students have invented a drone (無(wú)人機(jī)) that can observe more places than a plane. 西班牙大學(xué)生發(fā)明了無(wú)人機(jī)，能觀察更多地方。第三段最后一句After each flight, the drone can bring back detailed information about where rhinos are found, the conditions of water and plants in the area, and the positions of suspected poachers.每次飛行之后無(wú)人機(jī)能帶回詳細(xì)信息，在哪里能找到犀牛，在這個(gè)地區(qū)水和植物的條件狀況和嫌疑偷獵者的位置。可知D項(xiàng)符合題意。

Like many foreigners, I only know two words of Chinese (“hello” and “thank you”) when I came to China in 2015. Since tasks like ordering food or taking a taxi was quite stressful, so I signed up for classes. Because my teacher was very helpful, I didn't learn enough to have a conversation on. Finally, I found that the best way learn Chinese is to make friends with native speakers and spend time with him. Gradually, I learned enough Chinese to take care of a few complicated tasks. Besides, visits to the bank, and anything else which involves technical language, are still tough for me. Nowadays, more foreigners than ever are studying Chinese. I can understand how; It's a fascinating language, and there are always new words waits to be discovered.

More and more foreigners like to come to China. Last Friday our school was invited a foreign teacher in our city give a class to the students of Senior Grade Two. We found his class interested. I learned a lot from him. The teacher had a free talk to us with easy English . He spoke slow so that we could understand him well. Sometimes he repeated what we don't understand. My classmates were all active in the class. To his joy, I understood everything the teacher said. And I was able to ask question in English. This class encouraged me very much. I'm sure that until we keep on practising, it will be easy for us to learn speaking English well.
