不知道大家有没有遇到这个问题：单词背也背了（有时背得还很辛苦），但就是用不出来（口语&写作中）
其实解决方式也不难：
1. 结合原文和大量例句看别人是怎么用的（这个过程叫“输入”）
p.s. 例句不要只看1个，否则自己还是学不到在【不同的语境中】该词的用法，这也是我会一个单词配好几个例句的原因
2. 自己造句（这个过程叫“输出”），通过造句，你就“逼”自己不得不思考“我可以把这个词用在哪呢？”“用的时候要注意什么？”等等问题，你在【主动学习】，那以后在口语或写作中，你当然就可以自然而然地用出来了，不需要在“用词”上烦恼了，只需要focus在你口语/写作的“内容”上，这才是核心，所以，记得完成页面底部的“趁热打铁”部分，要学就学透了，要学就追求高质量！
原 文 泛 读NASA Astronauts Wrap Up Historic All-Woman Spacewalk
At 2:55 p.m. EDT Expedition 61 Flight Engineers Christina Koch and Jessica Meir of NASA concluded their spacewalk the first with only women. During the 7-hour 17-minute spacewalk the two NASA astronauts completed the replacement a failed power charging component also known as a battery charge-discharge unit (BCDU). The BCDU regulates the charge to the batteries that collect and distribute solar power to the orbiting lab’s systems. Mission control activated the newly installed BCDU and reported it is operating properly.
The astronauts were also able to accomplish some get-ahead tasks including installation of a stanchion on the Columbus module for support of a new external ESA (European Space Agency) payload platform called Bartolomeo scheduled for launch to the station in 2020.
Commander Luca Parmitano of ESA and NASA Flight Engineer Andrew Morgan assisted the spacewalkers. Parmitano operated the Canadarm2 robotics arm and Morgan provided airlock and spacesuit support.
It was the eighth spacewalk outside the station this year. Space station crew members have now conducted 221 spacewalks in support of assembly and maintenance of the orbiting laboratory. Spacewalkers have spent a total of 57 days 20 hours and 29 minutes working outside the station.
It was the first spacewalk for Meir and the fourth for Koch who now has spent a total of 27 hours and 48 minutes spacewalking. It is the first spaceflight for both women who were selected in the 2013 astronaut class that had equal numbers of women and men. Koch arrived to the orbiting laboratory in March 2019 and will remain in space for an extended duration mission of 11 months to provide researchers the opportunity to observe effects of long-duration spaceflight on a woman to prepare for human missions to the Moon and Mars.
Meir became the 15th woman to spacewalk and the 14th U.S. woman. It was the 43rd spacewalk to include a woman. Women have been performing spacewalks since 1984 when Russian cosmonaut Svetlana Savitskaya spacewalked in July and NASA astronaut Kathryn Sullivan spacewalked in October.
The faulty BCDU is due to return to Earth on the next SpaceX Dragon resupply ship for inspection. Station managers will reschedule the three battery replacement spacewalks for a future date. In the meantime the five planned spacewalks to repair a cosmic particle detector the Alpha Magnetic Spectrometer are still on the calendar for November and December.

语法/长难句分析The astronauts were also able to accomplish some get-ahead tasks including installation of a stanchion on the Columbus module for support of a new external ESA (European Space Agency) payload platform called Bartolomeo scheduled for launch to the station in 2020.
自己先试着分析：
1. 整句话的主干是什么？
2. 加粗的成分是什么？其内部结构是什么？
整句话的主干：
The astronauts were also able to accomplish some get-ahead tasks
加粗成分分析：
1. including... 是对tasks的举例
2. called...是过去分词作后置定语修饰payload platform，scheduled是过去分词作后置定语修饰Bartolomeo，这两个后置定语都相当于省去了which is的定语从句
趁 热 打 铁任选上面7个词中的1个造句，下方评论告诉我哦，会一一回复哒～
