Not many people are interested in spending time, money, and effort to learn a foreign language these days. They think that knowing their mother tongue and the English Language is good enough. ___1___ I feel strongly that everyone should learn at least one other foreign language in their lifetime.
The most obvious benefit of knowing another language is that you can communicate more easily with people from different parts of the world. You will be able to learn more about another culture and form new friendships. Traveling to other countries would be easy. ___2___ In addition, you will be able to enjoy more variety in entertainment and reading material.
___3___ Students who learn an additional language besides English are known to do better in English and Mathematics. This is because the skills involved in learning a new language such as analytical skills are equally important in learning other subjects. As you learn a new language, you practice these skills and become even better.
Finally, the ability to communicate in another language is valuable when you want to get a job. ___4___ This is why you will be able to deal with people from other parts of the world.

Learning a foreign language does not only make it easier for you to find a job but also makes you more valuable to your employer.
In conclusion, there are many benefits that come from learning a foreign language. Therefore, I strongly recommend that everyone learn an additional language. ___5___
A．The benefits gained are worth the time and effort spent. 【因果关系|同义复现】
B．Imagine being able to read and understand Japanese cartoons.
C．You will have the advantage over those who know fewer languages. 【this 指代|因果关系】

astronauts on the USSR’s Soyuz 11 and America’s Challenger died during their__________(mission). 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 _______(orbit) Earth and has astronauts from different countries on board, providing a continuous human presence in space.
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 ______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 Tianzhou1 __________(dock) with it. This _________(signal) 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.

Today, space technologies are widely used in all kinds of___________(industry), and everyday products such as GPS, memory foam pillows, and smartphone cameras are changing our lives.
Finally, sending astronauts into space has helped people to think about the world’s problems and even to find ways to solve them.

假定你是某国际学校的学生李华,你发现你校大多数学生天文学知识匮乏,请用英语给校长Mr. Smith写一封信, 内容包括:1. 说明问题;2. 分析原因;3. 提出解决办法。
Dear Mr. Smith,
Recently I found most students in our school have little understanding of astronomy.
There are mainly two reasons for this. One reason is that we don’t have enough access to astronomy. The other is that some students find astronomy difficult and have no interest in it. To improve the situation, I think, first, our school library should provide more books about astronomy so students can borrow and read them. Moreover, we can set up an astronomy club, ①in which students can learn and share their knowledge about astronomy (学生能学习并分享他们的天文学知识). Finally, we can hold competitions regularly, ②which will awaken/arouse students’ interest in learning astronomy (这将激发学生对学习天文学的兴趣).
Thanks for your time. I hope you can consider my advice.
Yours,
Li Hua
