一、题文

【题文】Named after the “quest for heavenly truth”, Tianwen 1, China’s first Mars probe（探测器）, has given us impressive pictures of the red planet. The first high-resolution（高分辨率的）pictures of Mars taken by Tianwen 1 were made public by the China National Space Administration（CNSA） on March 4. “These are the first close-up pictures of Mars’ surface taken by China, ” said Bao Weimin, a scientist of the Chinese Academy of Sciences. The pictures were taken at different distances from Mars. The two black-and-white pictures were taken by the high-resolution camera on Tianwen 1 when the probe was about 330-350 kilometers above the Martian surface. As for the color picture, it was taken by Tianwen 1’s medium-resolution（中分辨率的）camera when the probe was about 5, 000 kilometers above the red planet. It shows Mars’ North Pole. The high-resolution camera can take both color and panchromatic（全色的）pictures. Panchromatic pictures, which are black and white, are the clearest, having the largest amount of data for scientific study, said Liu Tongjie. The medium-resolution camera, can only produce lesser clear pictures. Scientists put the panchromatic and color pictures together to form a clear and beautiful color picture, Liu added. Tianwen 1, the country’s first independent Mars task, was sent up on July 23, kicking off the nation’s planetary exploration program. The probe entered its preset orbit above Mars on Feb 24 and is looking for a landing site on the planet’s largest plain. The probe is expected to land on the red planet sometime between May and June.【小题1】When were the first high-resolution photos of Mars made public by CNSA?A．On Feb 24.B．On March 4.C．On July 23.【小题2】What does the word “It” refer to in paragraph 3?A．The color picture.B．The black-and-white picture.C．The clear and beautiful picture.【小题3】What do we know about the pictures according to the text?A．The first close-up pictures of Mars’ surface were taken at different distances from Mars.B．The color pictures have the largest amount of data for scientific study.C．The clearest pictures were taken by the medium-resolution camera.【小题4】What will be most probably discussed next?A．Tianwen 1 will take more pictures of Mars.B．Tianwen 1 will land on the red planet, Mars.C．Tianwen 1 will do some scientific research on Mars.

二、解答

【答案】【小题1】B【小题2】A【小题3】A【小题4】B

三、分析

【解析】【分析】本文介绍了中国首次火星探测任务及首个火星探测器“天问一号”。【小题1】细节理解题。根据“The first high-resolution（高分辨率的）pictures of Mars taken by Tianwen 1 were made public by the China National Space Administration（CNSA） on March 4.”可知第一张火星的高分辨率照片是在3月4日公布的。故选B。【小题2】词义推断题。根据划线词的上一句“As for the color picture, it was taken by Tianwen 1’s medium-resolution（中分辨率的）camera when the probe was about 5, 000 kilometers above the red planet. ”可知it指代的是中分辨率相机拍摄的彩色照片。故选A。【小题3】细节理解题。根据“The pictures were taken at different distances from Mars.”可知the pictures指代“These are the first close-up pictures of Mars’ surface taken by China...”中的特写照片，因此特写照片是从火星不同距离拍摄的。故选A。【小题4】推理判断题。根据最后一段最后一句“The probe is expected to land on the red planet sometime between May and June.”可知该探测器预计将在5月至6月之间的某个时候登陆这颗红色星球。因此之后很有可能讨论天问一号登陆火星。故选B。
