When I saw the tragic scenes on the news, I felt it was my duty as a doctor to go there and offer my help. I knew I was putting my life at risk, but I thought, “If I don’t do it, who will?” It is important to remember that Ebola doesn’t respect national boundaries. There are no borders for doctors, for patients or for anyone else involved in combating this terrible disease. involved in...作anyone else的后置定语 =... anyone else who is involved in... My mission was to relieve Emma, a Canadian specialist in infectious diseases at the end of her posting. Emma spent an hour with me in the staff room talking me through the daily routine. As she talked, I could hear at least three different languages being spoken at the tables around us. 熟词生义 relieve v. 给某人换班 posting n. 派驻，派任 talk sb through sth 向某人详细解释某事 hear sth done hear sth being done Later, Emma introduced me to some of the others working for or alongside MSF: Wilton, a young local man, who helped carry the very sick into the treatment clinic and who disinfected clothing and surfaces; Maisy, a retired public health official from Darwin, Australia, whose local team of volunteers educated people on preventing infection; Alfonso, a soft-spoken Argentinian doctor in his 50s, who had previously worked on Ebola outbreaks in Sierra Leone and Guinea. The list went on. I found that I was the only Chinese doctor among people of all ages, colours and beliefs, from every continent except Antarctica. With each person I met, I felt a growing sense of pride as part of this extraordinary team, whose devotion to the cause shone from their eyes. be devoted to (doing) sth / devote oneself to (doing) sth 献身于，致力于 In the few weeks since then, I’ve come to know these people very well. We have worked together, surrounded by blood, vomit and death. But, although the death rate is very high, we will never give up on a patient, and efforts do sometimes end in miracles. 8 Just after my arrival, a family of six were brought here in the back of a van. All of them were infected. The twin girls and their parents soon died. We knew there was a little hope for the brothers, but we did everything we could to save them. When we visited the ward the next morning, we were amazed to see that against all odds, both boys were still alive. Pascal and Daniel have since made a full recovery. This small but unexpected success compensated for弥补 many other less fortunate cases. that省略定语从句 ...but we did everything that we could do to save them 9 To be caught up in困入 such a crisis creates powerful bonds between people, not only between carers and patients, but also between all those who have come from different parts of the world and joined together in a common cause. It is so inspiring to have colleagues like Wilton, Maisy and Alfonso, not to mention更不用说 all the others I have worked with. 10 Now my time is almost up. In a few days, someone else will arrive to step into my shoes, and the tireless work that the MSF members do in more than 70 countries and regions around the world will go on. In a world still facing so many problems, it is absolutely essential for us to collaborate to create a global community with a shared future of peace and prosperity. facing...作world的后置定语 =In a world which/that still faces so many problems... 11 (教材P52) It is not the first time the author has worked with MSF． (1)It/This/That is the first/second...time that.have/has done It/This/That was the first/second...time that.had done 这/那是某人第一/二……次…… (2)It’s time to do sth．是做某事的时候了。 (3)It’s (about/high) time (that)..should do/did. 是做某事的时候了。 It/This/That is the first/second...time that... 这/那是某人第一/二……次…… ①the first time可以引导时间状语从句，意为“第一次”。 The first time I made a speech in front of so many people, I felt quite nervous. 我第一次在这么多人面前演讲时，感到很紧张。 ②for the first time意为“第一次”，作时间状语。 She came to Beijing for the first time when she was eight. 她八岁的时候第一次来北京。 [即学即练]——单句语法填空/完成句子 ①You have now finished your first sprint，so it's time _______ (start) on the next one． ②(应用文之倡议书) It is high time that we ________________(take) some measures to protect the wild animals． ③ (应用文之欢迎辞)欢迎来到我的家乡。这是你第一次来到这里。让我告诉你去我家的路。 Welcome to my hometown．___________________________________．Let me tell you the way to my home． to start took/should take This is the first time (that) you have come here Homework 1. 背新P88-89派生词汇 2. 翻译句子 3. 分层作业P221-223 (七选五选做) Translation 1.这是她第二次被选为学生会主席。 It/This is the second time that she has been elected as the president of the Students’ Union. 2. 人们开始重视垃圾分类已经有五年了。 It has been/is five years since people started to attach importance to garbage classification. 3. 要再过十年，这种环保材料才会在日常生活中广泛应用。 It will be ten years before this environmentally friendly material is widely used in daily life. $$
