1 Dear John,
Whenever someone has eaten some unusual meat, the question “what did it taste like?” is asked. People usually say chicken; but they know that it really did not taste just like chicken. Try this one yourself. What does beef taste like? Yourreply? Pork? Chicken? No. Beef tastes like beef. What is a spacewalk like? Like a spacewalk. But let me give you the “sorta like chicken” answer, so that you at least have a feel for it.
pork n. 猪 肉
spacewalk n. move in space outside a space craft 太空漫步,太空行走
But let me give you the “sorta like chicken” answer, so that you at least have a feel for it.

(译文)亲爱的约翰:
要是有人吃了一些不同寻常的肉,别人会问:“这肉是什么味道呢?”人们通常会说像鸡肉;但是,他们心里清楚,这肉尝起来真的不像鸡肉。你自己也试一下。牛肉尝起来是什么味道呢?你的回答是?猪肉?鸡肉?不。牛肉尝起来就像牛肉。太空行走是什么样子呢?就像太空行走。但是,让我给你一个“有点像鸡肉”的答案,这样你就至少对它有点感觉。
2 Imagine you are in scuba gear.Your vision is restricted by the size of your underwater mask. Your fins, wetsuit, and gloves make you clumsy and heavy.

Meanwhile, he must work. After his job is complete, he and hiscrew return to 4. the airlock, where they eat dinner, do morework, and then go to bed, and where 5. they sleep soundly—all tasks accomplished.

Task 3Note answers to the questions below. Discuss with a partner.
1. Why is it so important that an astronaut's gear functions properly in outer space?
Suggested answer:
It is so important that an astronaut's gear functions properly in outer space because there is no air to breathe in outer space, and one malfunction could cost the astronaut his/her life.
2. Why is an astronaut constantly floating while in outer space?
Suggested answer:
An astronaut is constantly floating while in outer space, because inouter space there is no gravity to pull the astronaut towards the Earth.
3. What do you think is one quality that someone who wants to be an astronaut should possess?Why?
Suggested answer:
I think that someone who wants to be an astronaut should be a calm person. Being an astronaut is a dangerous job, and space flight is uncomfortable to the body.

From initially looking up and gazing at the stars, man has invented tools like the 1. telescope to magnify and clearly see the yet unseen. While we think of 2. astronomy, the study of celestial objects and outer space as a completely modern field of study, our interest in the worlds beyond the Earth can be traced back to ancient times.
Datingback to 1,800 B.C., the Babylonians were among the first 3. civilization to document the movements of the sun and the moon. They maintained a very detailed 4.record of these motions including a daily, monthly, and yearly position of the celestial bodies.

One of the most well-known of these pioneers was Pythagoras, a mathematician who postulated that the earth is 7. spherical inshape as other celestial bodies are. He came up with this idea when he saw ships disappear past the 8. horizon as they sail.
Ancient Egyptians also made significant 9. contributions to the study of outer space. For example, they built huge pyramids based on the positions of the moon and stars, such as the Great Pyramid of Giza. It was built to 10. align with the North Star, which at that time was Thuban instead of Polaris.

Task11 Passage translation
Translate the following passage into English. Try to use the words and phrases from Passage A as many as possible.
在 20 世纪 50 年代和 60 年代,苏联和美国率先进行现代空间探索,中国基本上是局外者。直到 2003 年,中国才将一名宇航员送入太空,但现在它正在迎头赶上。2019年 1 月,嫦娥 4号探测器(the Chang'e-4 probe)首次在月球远端进行软着陆。这不是中国月球探索的结束,它将进一步探索未知领域。中国还计划在 2020 年在火星上发射探测器(probe),成为世界上首个实行该计划的国家。到 2030年,中国已经设定了目标——将火星样品带回地球并将中国宇航员送上月球。这些计划将推动中国成为太空探索的主要参与者。
For your reference:
In the 1950s and '60s, the Soviet Union and the United States pioneered modern space exploration. China was largely uninvolved in this endeavor. The country didn'ts end an astronaut into space until 2003. But now China is making strides in space exploration. In January 2019, the Chang'e-4 probe made the first-ever soft landing on the far side of the moon. Rather than end its lunar exploration, China will continue to venture further into the unknown. China is also planning to launch a probe to Mars in 2020, becoming the first country to do so. In addition, China has planned to bring samples from Mars back to Earth, and send Chinese astronauts to the moon by 2030. These programs will establish China as a major force in space exploration.
