阅读“七选五”要求考生根据文章的结构、逻辑、上下文的内容选出相应的五句话填入空白处将文章补充完整,其目的在于“考查考生对文章的整体内容和结构以及上下文逻辑意义的理解和掌握。”
做题时需要明白整篇文章的主旨,文章整体的思路和每一段的用意以及作者写作的意图,理清段落之间和句子之间的逻辑关系也有助于把握文章的整体结构和思路。
【解题策略】
1. 从意思上判断
2. 从词汇上锁定线索
关注空白前后的名词和动词,然后在选项中查找它们的近义词、反义词、同义词、同类词等。其次是一些专有名词,比如说数词、代词、时间、年代、地点/名称等。
3. 从关联词作为切入点
英语的句段之间经常会运用关联词表示过渡和衔接,让文章的思路与更清楚、逻辑更连贯,因此文章中和选项中表示各种逻辑关系的路标性信号词在选择答案时都是很重要的线索。

“Are we alone What’s out there ” Looking up at the stars, people have always wanted to learn more about space, and scientists work hard to find answers. They make vehicles to carry brave people into space to find out the secrets of the universe. They also really wish to discover other planets that are suitable enough to support life.
Para 1
Para 1 : Humans have always had _____________________about space.
a natural curiosity
Para 2
Before the mid-20th century, most people felt travelling into space was an impossible dream. However, some scientists were determined to help humans realise their dream to explore space. After many experiments, they succeeded in making rockets that could escape Earth’s gravity. On 4 October 1957, the Sputnik 1 satellite was launched by the USSR and successfully orbited around Earth. Afterwards, the USSR focused on sending people into space, and on 12 April 1961, Yuri Gagarin became the first person in the world to go into space. Over eight years later, on 20 July 1969, American astronaut Neil Armstrong stepped onto the moon, famously saying, That’s one small step for a man, one giant leap for mankind.” Following this, many more goals were achieved. For example, America’s NASA space agency launched Voyager 1on 5 September 1977 to study deep space, and it still transmits data today.
Para 2:Space travel became a ______in the 20th century, with American and Soviet space missions.

Para 3
Although scientists try to make sure nothing goes wrong, accidents can still happen. All the astronauts on the USSR’s Soyuz 11 and America’s Challenger died during their missions. These disasters made everyone sad and disappointed, but the desire to explore the universe never died. This is because people believe in the importance of carrying on space exploration despite the huge risks. An example of this ongoing work is the International Space Station. It orbits Earth and has astronauts from different countries on board, providing a continuous human presence in space.
Para 3: Space travel has always involved__________, but despite the risks ___________continues.
great risk
exploration
Para 4
China's space programme started later than those of Russia and the US, but it has made great progress in a short time. China became the third country in the world to independently send humans into space in 2003, when Yang Liwei successfully orbited Earth in the Shenzhou 5 spacecraft. Then Shenzhou 6 and 7 completed a second manned orbit and the first Chinese spacewalk, followed by the vehicle Jade Rabbit being sent to the moon to study its surface. After that, China launched the Tiangong 2 space lab into space and Tianzhou 1 to dock with it. This signalled one step further in China’s plan to establish a space station in the future. More recently, China has sent Chang'e 4 to explore the surface of the far side of the moon to make measurements and observations.
