For those （65）whodo not know what Descendants of the Sun is about，it is a drama about the love of people who get （66）closeras they learn to be considerate of each other in desperate times．It is also about the sacrifices made by people who throw themselves （67）intonatural disasters．Captain Yoo Shi Jin（柳大尉）（Song Joong Ki宋仲基） is the team leader of the Special Warfare Command of the United Nations Peacekeeping Troops．By request of the UN，he is （68）stationed（station） in the war-torn country of Uruk（乌鲁克）．（69）Therehe meets Kang Mo Yeon（姜暮烟）（Song Hye Kyo宋慧乔），a volunteer doctor with Doctors Without Borders．（70）when/asthey work alongside each other，they clash and fall in love．

3．My grandfather is a（61）retired （retire） worker．On summer evenings，he would gather us outside the house to enjoy the cool air，（62）sharing （share） his experiences before liberation．
At the age of fourteen，my grandfather worked as a child laborer in a coal mine．One day，he and his two workmates were working in the tunnel（63）when an unfortunate thing happened．A part of the tunnel fell down and they were shut in．They had no food（64）toeat （eat） in the tunnel．When they were hungry，they only drank some water．Because （65）it was very cold there，they just hug one another in order to keep warm．They could hardly speak or move as a consequence of physical（66）weakness （weak） and thought they would die．
After（67）what seemed a long time，the tunnel was dug through and they（68）wererescued （rescue）．They had been trapped there for fourteen days!My grandfather said they weren't let out at once．If so，they（69）would havedied （die）．They were kept at the entrance to the tunnel where it was very dim and were fed on some thin porridge．After a day or two，they had recovered a bit and were（70）eventually （eventual） helped out．

2．No Grammar Errors
I prefer Lynne Truss's words：I am a grammar"sticker"．And，like Truss-author of Eats，shoots & Leaves-I have a"zero tolerance"approach to grammar mistakes that make people look stupid．
Now，Truss and I disagree on what it means to have"zero tolerance"．She thinks that people who mix up basic grammar"deserve to be struck by lightning，and buried in an unmarked grave"，while I just think they deserve to be passed over for a job-even if they are otherwise qualified for the position．
Everyone who applies for a position at either of my companies，iFixit or Dozuki，takes a compulsory grammar test．If they can't distinguish between"to"and"too"，their applications go into the bin．
Of course，we write for a living．iFixit．com is the world's largest online repair manual （指南），and Dozuki helps companies write their own technical documentation（证明文件），like work instructions and step-by-step user manuals．So，it makes sense that we've made a strong strike against grammar errors．
But grammar is relevant for all companies．Yes，language is constantly changing，but that doesn't make grammar unimportant．Good grammar is credibility，especially on the Internet．And，for better or worse，people judge you if you can't tell the difference between"their""there"and"they're"．
Good grammar makes good business sense-and not just when it comes to hiring writers．Writing isn't in the official job description of most people in our office．Still，we give our grammar test to everybody，including our salespeople，our operations staff，and our programmers．
Grammar signifies more than just a person's ability to remember high school English．I've found that people who make fewer mistakes on a grammar test also make fewer mistakes when they are doing something completely unrelated to writing．Applicants who don't think writing is important are likely to think lots of other things also aren't important．

1．The truth（61）thattrees are vital to our life is not a secret．They provide us with food，wood and most（62）importantly（importance），oxygen．Now there is one more thing we can add to this list-blocking out harmful bacteria from water．
The discovery（63）was made（make） by a team consisting of scientists from the Massachusetts Institute of Technology （MIT） and high school students who were seeking a（64）natural（nature） water filter（过滤器）-one that would help communities in developing countries that do not have access to modern water filter systems．
The（65）researchers（research），led by Professor Rohit Karnik，decided to turn to trees for help because they could allow liquid to flow through，while（66）blocking （block） out air bubbles．
They began by cutting 1.5-inch-wide sections of tree bark from the branches of a white pine tree．The people related then tested the wood's filtering ability by pouring water containing red dye particles of different sizes through．（67）Totheir amazement，they found that it was effective in trapping all the articles．（68）Encouraged（encourage），the team conducted（69）anotherexperiment，this time with water（70）thatcontained bacteria．Sure enough，the sapwood held back 99% of the bacteria，allowing only 1% to flow through．
