4. We ________our new neighbors yet, so we don’t know their names. A. don’t meet B. won’t meet C. haven’t met D. hadn’t met
答案为C。yet在这里几乎是使用完成时态的 标志，根据句意又可以推断出前半句的意思 是我们到现在还没有见过新邻居，故使用现 在完成时。现在完成时在此表示过去发生的 某一动作对现在造成的影响。
5. I won’t tell the student the answer to the math problem until he _______ on it for more than an hour. A. has been working B. will have worked C. is working D. had worked
3) It can be inferred from this text that _________.
A. there is no doubt that solar cars have been more and more popular B. you can take a long trip by solar car C. solar cars are cheap, clean and safe D. Marie Logan is a professor from Queensland University
Answer:
B
4) All the facts are mentioned except for______. A. solar cars will not pollute the environment B. a lot of people haven’t realize the potential of solar cars C. solar cars speed is becoming faster D. solar cars shapes are special Answer: D
答案为C。在本题中in the last three months决 定了要使用完成时态；从句意中可以推断出 此处不是以过去某个时间点为基点的，故不 用过去完成时。现在完成进行时在本句中表 示从过去一直持续到现在、刚刚或即将停止 的动作。
8. Since she saw the old film last week, she _______ the old song for many days. A. is singing B. has been singing C. sings D. sang
答案为D。理解句意：这家电厂为这个城 市供电三年了，它们的合作还会继续。for three years确定了要使用完成时态；现在 完成进行时在此句中表示过去的动作持续 到现在，而且还将继续进行。
7. He ______ for a project in Russia in the last three months and he will return home soon. A. had worked B. works C. has been working D. is working
T
2) She has won most of her races.
F
She has taken part in six races and has won two of them.
3) The team has nearly finished building “Rainbow”. They haven’t finished yet. 4) Marie has written a book about solar energy. She has only written the first few chapters. 5) Solar cars can work even in cloudy weather.
答案为A。由句意可知，在学生研究这道题 目的时间满一个小时之前“我”都不会告诉 他答案，从句意推断，这里强调的是动作持 续一段时间而且还在进行，所以应该用现在 完成进行时。
6. The power station ________ electricity for the city for three years and their cooperation will continue. A. provided B. was providing C. provides D. has been providing

答案为A。in the past two years 意为“在过去 的两年里”，最常与其搭配的时态就是现在 完成时。通常句中有时间状语in the past / previous ... years / centuries / days时，要用现 在完成时。

Grammar
Present Perfect and Present Perfect Continuous
现在完成进行时与现在完成时的区别
(1) 现在完成时可以表示一个已经完成的动 作，而现在完成进行时则表示一个正在进 行的动作： I have read the book. 我读过这本书。 I have been reading the book. 我一直在读这本书。
答案为B。give 后接双宾语，the right change 作直接宾语，customers作间接宾语，所以当 customers作主语时，谓语动词要用被动语态。 根据句意顾客被要求在离开商店前确认已被 找零，表示某事发生前已经完成的动作，故 使用完成时态。
3. My friend, who _____________ on the International Olympic Committee all his life, is retiring next month. A. served B. is serving C. had served D. has served
(2) 现在完成时通常只陈述事实，而现在完成进 行时还可表示一种感情色彩： I have waited for two hours. (陈述事实) I have been waiting for two hours. (等得好辛苦 )

北师大版高三英语选择性必修第三册(2020版_U9_L3_Epidemics_Explain参考译文
Unit9 Lesson3 Epidemics Explained 参考译文第三课流行病探因流行病是指在短时间内（通常两周或更短）迅速在大量人群中传播的传染性疾病。
自地球上有人类生活以来，流行病就一直存在。
它们可能由不同因素引起，例如病毒被带入某个地区，或者由于人们生活方式的改变，比如说某一地区居住的人群增多，从而增加了接触细菌或病毒的几率。
只有致死病例达到一定数量，某种疾病才会被正式定性为流行病。
每种疾病的死亡数量各不相同。
罕见疾病的基线很低，即使某一地区只出现少数病例，也会被认定为是流行病；与此相反，常见疾病的基线较高，如流感。
普通感冒由一种广泛传播的病毒引起，可感染数百万人，但它并没严重到可以被称为流行病。
最近有新闻报道，吉姆·史密斯将禽流感和过去致命的流行病做对比，在屡屡令人感到沮丧的流行病史中寻找线索，从而创造一个远离流行病的美好未来。
禽流感自1997 年首次出现以来，已经夺去了一百多人的生命。
科学家们仔细研究了1918 年西班牙流感死亡者尸体的组织样本，证明禽流感是该病毒的现代变异版本，许多人担心它可能会引起下一场全球流行病。
人类有记载的最早的流行病，大约发生在公元500 年至550 年之间。
现今科学家估计，发病区域多达50% 的人口死于这一流行病，成为罗马帝国衰落的一个主要原因。
接着，14 世纪30 年代，这一流行病又卷土重来，这次发生在亚洲，并迅速传播到欧洲。
由于患者身上会出现明显的黑斑症状，这种流行病被称为“黑死病”。
几个世纪后，第一次世界大战快结束时爆发了1918 年大流感，又称西班牙流感。
刚刚熬过战争的人们现在不得不埋葬他们死于疾病的亲人。
战争引发的人口流动前所未有，从而导致这一流行病蔓延到全世界。
西班牙流感在18 个月内造成5000 万人死亡，成为历史上最严重的流行病。
死于该病的人比死于战争的人还要多。
最初，人们以为这种大规模流行病不会再对人类构成威胁，直至非典出现，再次让全球陷入担忧。

Unit 9 LearningLesson 3 The Secrets of Your MemoryPeriod 1教材分析本课为第九单元的阅读课，介绍的是关于人类记忆的秘密。
文章由问题展开，共分四部分，每部分均采用“问题—分析—建议”这一模式。
首先探讨了人们为何拥有儿时记忆，强调了“触发情绪变化”和“复述事件”的重要性；紧接着指出所谓“过目不忘”并无科学依据，但确实存在记忆力超群的人；作者随后介绍了记忆曲线，强调了及时复习的重要性；最后指出人的记忆力会随着年龄增长而逐渐衰退，25岁为记忆鼎盛期。
本文属于“人与自我”主题，旨在帮助学生正确认识关于记忆的那些“奥秘”，破除原有的误解，准确锁定加深记忆的关键因素，鼓励学生运用科学方法，强化记忆，提升学习效率。
