A tour of the space station
At the beginning of the class, Wang, the first female taikonaut to enter China’s space station, gave the students a tour of their living and working areas with the assistance of her two male crewmates.
授课一开始，入驻中国空间站的第一位女航天员王亚平在两位男乘组同事的协助下，带学生们“参观”了他们的生活和工作区域。
参观空间站
taikonaut n. 中国宇航员（taiko + naut）
with the assistance of 在……的帮助下
crewmate n. 同机工作的机组成员（crew + mate）
【拓展】astronaut，cosmonaut，taikonaut辨析：
这三个单词都表示宇航员。在英语国家，宇航员被称为astronaut，这个单词来自希腊语 astron （星星）；以及nautes（水手），所以，该单词就是“星际水手”的意思。
而俄罗斯的宇航员被称为cosmonaut，这个词是从苏联继承下来的。二战后出现了美苏争霸，苏联为了在语言上跟美国划清界限，采用了自己发明的cosmonaut。该单词来自希腊语kosmos（宇宙）和nautes（水手），所以该单词就是“宇宙水手”的意思。
而taikonaut的前缀taiko来自中文“太空”的拼音，naut是船员的意思，合起来就是“太空船员”。随着中国航天事业的发展，外媒也逐渐开始使用taikonaut来称呼中国宇航员。
She showcased their bedrooms and toilet, a fully functional kitchen where the taikonauts prepare their meals each day, the area where they conduct scientific experiments and their fitness equipment, including a treadmill (跑步机) and a spin bike.
她展示了他们的卧室、厕所和一个功能齐全的厨房，航天员们每天就在这里做饭；还展示了他们进行科学实验的地方，以及他们的健身设备，包括一台跑步机和一辆动感单车。
showcase v. [名词动化] 展示（show + case）
functional adj .功能的；实用的（function + -al）
conduct a scientific experiment 进行科学实验
fitness n. 健身；健康（fit + -ness）
spin 旋转
a spin bike 动感单车
In the kitchen, she showed the students a microwave, a water dispenser (饮水机) and a mini-refrigerator from which she took out a fresh apple.
在厨房里，她向学生们展示了一台微波炉、一台饮水机和一个迷你冰箱，还从里面拿出了一个新鲜苹果。
mini-refrigerator n. 迷你冰箱（mini-小的；短的 + refrigerator）
In response to a Hong Kong student’s question about water, Wang said the water they drink is recycled, noting that there is no difference in taste between regular and recycled water. With a water recycling system, full use is made of every drop of water in the space station, she said.
在回答一名香港学生提出的关于水的问题时，王说他们喝的水是循环水，并指出普通水和循环水的味道没什么区别。她说，有了水循环系统，空间站里的每一滴水都得到了充分利用。
in response to 作为对……的回答 / 答复
note v. [熟词生义] 指出；特别提到
there is no difference in 在……上没有区别 / 差异
regular adj. [熟词生义] 普通的；一般的
make full use of 充分使用 / 利用
Scientific experiments in a zero-gravity setting
零重力环境下的科学实验
zero gravity n. 零重力（zero + gravity 重力）
setting n. 环境；背景（set + -ing）
After the tour, the trio (三人小组) demonstrated several scientific experiments under zero-gravity conditions.
参观结束后，三人展示了零重力条件下的几个科学实验。
demonstrate v. [课标新增词] 演示,示范；证明，证实；表现，表露
under … conditions 在……条件下 / 情况下
First, Ye demonstrated experiments related to cell growth in the weightless environment in space with a video clip (片段). They compared the growth and shape of cells in artificial gravity and zero-gravity to study their changing rules and mechanisms.
首先，叶用一个视频短片演示了与太空失重环境下的细胞生长有关的实验。他们比较了细胞在人工重力和零重力下的生长和形状，研究其变化规律和机制。
be related to 与……相关的
weightless adj. 失重的；似无重量的（weight + -less）
artificial adj. 人工的；人造的
mechanism n .机制；构造
Ye showed the students images of myocardial (心肌的) cells observed under a fluorescence (荧光) microscope.
叶向学生们展示了在荧光显微镜下观察到的心肌细胞的图像。
“They look amazing in space, as if they are beating,” he said, explaining that the beating and gleaming (闪光) occurred as the living cells had a bioelectrical reaction.
他说：“它们在太空中看起来很神奇，就像它们在跳动一样，”他解释说，这种跳动和闪烁是由于活细胞发生了生物电反应。
living adj. 活的；活着的
bioelectrical adj. 生物电的（bio- 生物的+ electrical电的）
Ye and Wang then demonstrated and explained why astronauts cannot walk in space like they did on the ground and how angular momentum (角动量) helps them turn around in zero gravity.
turn around 转身；转变
随后，叶和王演示并解释了为什么宇航员不能像在地面上那样在太空中行走，以及角动量如何帮助他们在零重力下转身。
The team also conducted an experiment to show how lack of gravity causes loss in buoyancy (浮力), an optics (光学) experiment using water refraction (折射) and explored effervescence (泡腾) in a weightless environment using a water ball.
该小组还进行了一个实验，展示缺乏重力如何导致浮力消失，利用水的折射进行光学实验，并利用水球探索了失重环境下的泡腾现象。
lack of 缺乏（近shortage of）
The Shenzhou-13 crew went into space aboard the Shenzhou-13 spaceship and entered the Tianhe core module on October 16, embarking on their six-month stay in space, which is China’s longest-ever crewed mission so far.
神舟十三号机组人员乘坐神舟十三号飞船进入太空，并于10月16日进入天和核心舱，开始了他们为期六个月的太空之旅，这是中国迄今为止时间最长的载人任务。
embark on / upon 开始（新的或艰难的事情）；从事；着手
longest-ever adj. 史上最长的
crewed mission 载人任务
so far 到目前为止；至今
This is the second space lecture given by taikonauts. In June 2013, Wang Yaping, assisted by the other two crew members on the Shenzhou-10 spacecraft, delivered the country’s first live space lecture to over 60 million teachers and schoolchildren across China.
这是第二次由宇航员进行的太空讲座。2013年6月，王亚平在神舟十号飞船的另外两名机组人员的协助下，向中国各地6000多万名教师和学生进行了中国首次太空直播讲座。
