Yet I can never go back to live in my home because I just keep thinking: what if it does happen again? Earlier in the day I had 1 for the unlikely event of a flood. It had been raining that week, and authorities had issued a flood 2 , though not for where I was. Still, I’d placed 3 on the floor outside my garden door in case of the flooding water. Before my friends left, they laughed at me for doing that, but I thought, why take a 4 ? It was after midnight when I was awakened by the 5 sound of rushing water as if I were lying beside a waterfall instead of in my bedroom. I thought it could be a burst pipe. Trembling and in darkness, I grabbed my cell phone and turned on the flashlight. It wasn’t a burst pipe at all! Instead, water was 6 up through the gaps of the garden door. The water must have breached the sandbags. All around me, my things — chairs and lamps — began to 7 . I began to panic. The Ahr, usually such a quiet river, had 8 its banks. And now I had to get out — fast! It was pouring. In bare feet, I started to walk to my only 9 : the door that leads upstairs to the ground. All around me, things were breaking — the lamps were cracking, the cupboards were being 10 ． Finally, I 11 it to the door. I tried to push it open, but the 12 of the water wouldn’t let me. I tried several times, but the wild water slammed it shut again. I grabbed everything to open the door, and finally, in darkness, I leaped onto the stairs and ran outside 13 . What was once a lovely, cozy street was now a 14 , with floating trash and trees instead of people and cars. The river had drowned the neighborhood — and if I had woken up just a few minutes later, I would have drowned along with it. Don’t remember the day when you lost everything. Remember the day when you 15 . 1．A．prepared B．waited C．come D．shopped 2．A．map B．notice C．story D．warning 3．A．sandbags B．clothes C．boxes D．tools 4．A．chance B．risk C．break D．step 5．A．occasional B．wild C．natural D．faint 6．A．clearing B．shooting C．gathering D．flowing 7．A．change B．crash C．float D．disappear 8．A．approached B．burst C．occupied D．covered 9．A．gate B．position C．escape D．entrance 10．A．torn apart B．replaced with C．fixed up D．removed away 11．A．left B．took C．attached D．made 12．A．force B．course C．source D．surface 13．A．tirelessly B．helplessly C．awkwardly D．impatiently 14．A．mess B．field C．shelter D．habitat 15．A．suffered B．survived C．returned D．won 四、书信写作 （25-26高一下·江苏无锡·期中）假设你是李华，上周五你校邀请英国专家 George开展了一场关于自然灾害的云讲座（cloud lecture）。请你用英文为学校微信公众号写一篇报道，介绍该活动。 内容包括： 1. 活动目的； 2. 活动过程； 3. 活动反响。 注： 1. 写作词数80左右； 2. 可适当增加细节，使行文连贯。 Cloud Lecture on Natural Disasters by Expert George ________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ 学科网（北京）股份有限公司 $ Unit 4 Natural Disasters 核心语法精练 目录 1 二、考点夯基 4 一、单项选择 4 二、单句语法填空 11 三、综合提升 14 一、语法填空 14 二、完形填空........................................................................................................................ 三、阅读理解七选五 18 一、语法核心定义 1、定义： （1）在复合句中，修饰主句中的名词或代词（先行词）的从句，叫做定语从句。 从句由关系词引导，可对先行词进行限定、修饰或补充说明。 （2）被修饰的名词/代词叫先行词，连接先行词和从句的词叫关系词。 2、定语从句分为：限制性定语从句（无逗号、不可删）、非限制性定语从句。 3、完整公式：先行词+关系代词+从句（缺成分） 4、核心判定口诀：从句缺主宾，必用关系代词 二、关系代词 1. who（指代人） ✅ 适用：先行词为人，从句中作主语、宾语 ✅ 句式特点：作主语绝对不能省略；作宾语可省略 ✅ 例句1（作主语，不可省）：The girl who helped me is my classmate. ✅ 例句2（作宾语，可省）：The teacher (who) you met just now is from Beijing. 2. whom（指代人） ✅ 适用：先行词为人，从句中只能作宾语 ✅ 语体特点：正式书面用语，口语中常用 who 替换 ✅ 必考细节：可与介词提前连用（期末拔高考点） ✅ 例句：The boy whom we talked about is good at swimming. ✅ 介词提前：The boy about whom we talked is good at swimming. 3. which（指代物） ✅ 适用：先行词为事物、动物，从句作主语、宾语 ✅ 句式特点：作主语不可省，作宾语可省 ✅ 例句1（主语）：The book which lies on the desk is useful. ✅ 例句2（宾语）：The movie (which) we watched last night was wonderful. 4. that（万能关系代词） ✅ 适用：可指代人、物，从句作主、宾 ✅ 优势：兼容性最强，多数基础题型可通用 ✅ 例句：The people that live nearby are very kind. 5.whose ✅ 核心含义：表所属关系，翻译为“……的” ✅ 既可指人，也可指物（90%学生误区：以为只能指人） ✅ 固定结构：先行词 + whose + 从属名词 ✅ 句法功能：在从句中作定语，修饰后面名词 ✅ 指人例句：The student whose handwriting is excellent won the prize. ✅ 指物例句：I live in a house whose windows face the park. ✅ 等价替换：whose +名词 = of which + the +名词 例：a tree whose leaves are green = a tree of which the leaves are green 三、只用that，不用which/who的规则 1. 先行词被最高级修饰：the best, the most beautiful 例：This is the most interesting book that I have ever read. 2. 先行词被序数词修饰：the first, the last, the second 例：He is the first student that finished the task. 3. 先行词被不定代词修饰或本身是不定代词： all, everything, nothing, anything, much, little, few 例：Everything that he said is true. 4. 先行词被all/every/no/any/much等修饰 例：All the stories that he told are funny. 5. 先行词既有人又有物 例：We talked about the teachers and schools that we had visited. 6. 主句是以 who / which 开头的特殊疑问句 例：Who is the girl that is crying? 四、绝对不能用that的三种情况 1. 介词提前后，只能用 which/whom，不能用that ✅ The room in which I live is big. ❌ The room in that I live is big. 2. 非限制性定语从句（有逗号）不能用that 3. 先行词为专有名词、独一无二名词时，不用that 五、基础做题万能步骤 1. 找先行词：判断是人/是物 2. 分析从句：缺主语？缺宾语？不缺成分？ 3. 套特殊规则：是否最高级、序数词、不定代词、人物共存 4. 确定关系词、判断是否可省略 一、单项选择 1．（26-27高一·全国·暑假作业）The girl ________ is standing by the window is my classmate.

Fishermen, tourists, hotels, homes, and cars were swept away by huge waves 2 (cause) by the strong earthquake that reached a magnitude of 9.0. The undersea quake struck around 7:00 a.m., Sunday off the west coast of Indonesia’s Sumatra Island. In Sri Lanka, some 600 kilometres west of the quake centre, the number of 3 (death) stood at 2,498, and one million more were affected by the tsunami, government officials said. Indian officials said as many as 1,900 were killed along the southern coast. 4 254 were found dead in Thailand and 54 in three other countries. In southern Thailand, 1,900 people were hurt and many more were missing, local officials said. “I was having breakfast with my three children 5 water started filling my home. We had to leave everything and run to 6 (safe),” said Chandra Theeravit, a local Thai woman. Thousands of people are still missing, and the number of deaths is expected to grow even 7 (high) over the next few days. Foreign aid is 8 (organise) for the tsunami-hit countries.

Yet I can never go back to live in my home because I just keep thinking: what if it does happen again? Earlier in the day I had 1 for the unlikely event of a flood.

Trembling and in darkness, I grabbed my cell phone and turned on the flashlight. It wasn’t a burst pipe at all! Instead, water was 6 up through the gaps of the garden door. The water must have breached the sandbags. All around me, my things — chairs and lamps — began to 7 . I began to panic. The Ahr, usually such a quiet river, had 8 its banks. And now I had to get out — fast! It was pouring. In bare feet, I started to walk to my only 9 : the door that leads upstairs to the ground. All around me, things were breaking — the lamps were cracking, the cupboards were being 10 ． Finally, I 11 it to the door. I tried to push it open, but the 12 of the water wouldn’t let me. I tried several times, but the wild water slammed it shut again. I grabbed everything to open the door, and finally, in darkness, I leaped onto the stairs and ran outside 13 . What was once a lovely, cozy street was now a 14 , with floating trash and trees instead of people and cars. The river had drowned the neighborhood — and if I had woken up just a few minutes later, I would have drowned along with it. Don’t remember the day when you lost everything.

一、语法填空 阅读下面的短文，在空白处填入一个适当的单词或括号内单词的正确形式。 Passage 01 【答案】 1．killing 2．caused 3．deaths 4．Another 5．when 6．safety 7．higher 8．being organised 9．it 10．which 【导语】本文是一篇新闻报道。文章主要报道了一次由9.0级强震引发的、波及多国的毁灭性海啸，列举了各国惨重的人员伤亡和财产损失，并引述了亲历者的描述。 1．考查非谓语动词。句意：过去40年来最强烈的地震引发了一场海啸，海啸昨日袭击了亚洲各地的海岸线，在印度尼西亚、印度、泰国、马来西亚以及至少其他四个国家造成超过6500人死亡。句子主干成分完整，空处表示随着谓语行为自然发生的结果，作结果状语，应用kill“杀死”的现在分词形式。故填killing。 2．考查非谓语动词。句意：渔民、游客、酒店、房屋和汽车被这场强度达9.0级的强烈地震所引发的巨浪卷走。句子已有谓语，空处是非谓语，作huge waves的后置定语，cause“引 起”和huge waves逻辑上是被动关系，因此用cause的过去分词形式。故填caused。 3．考查名词复数。句意：政府官员称，在震中以西约600公里的斯里兰卡，死亡人数达到2498人，另有超过一百万人受到海啸影响。空处作介词of的宾语，结合空后的“stood at 2,498”可知，可数名词death“死，死亡”需用复数形式。故填deaths。 4．考查限定词。句意：在泰国又发现了254具遗体，在其他三个国家发现了54具。上文已分别列举了斯里兰卡和印度的死亡人数，此处是列举其他国家的数字，表示“（三者或三者以上中的）另外的，又一个”，空处应用another，句首单词的首字母需大写。故填Another。 5．考查连词。句意：我当时正和我的三个孩子一起吃早餐，这时水开始涌进我的家。空处前后均为完整的句子，结合“I was having breakfast with my three children”可知，此处是用be doing when…表示“正在做某事时，忽然……”。故填when。 6．考查名词。句意：我们不得不舍弃一切，逃往安全的地方。空处作介词to的宾语，名词safety符合题意，意为“安全”，是不可数名词。故填safety。 7．考查比较级。句意：仍有数千人失踪，预计未来几天死亡人数还会进一步上升。结合空前的“even”可知，此处表示程度加深，空处应用high的比较级形式。故填higher。 8．考查动词时态和语态。句意：正在为受海啸袭击的国家组织外国援助。空处和is构成谓语，结合前一句内容可知，本句表示动作正在进行中，时态应用现在进行时，organise“组织”和主语Foreign aid之间是被动关系，应用被动语态。故填being organised。 9．考查it的用法。句意：然而，危险的环境和受损的道路将使食品和物资的运送变得困难，这意味着救援工作将面临巨大挑战。根据“make”和“difficult to deliver food and supplies”可知，此处应用固定结构“make it+形容词+to do sth.”表示“使做某事变得……”，其中it作形式宾语，真正的宾语是后面的不定式。故填it。 10．考查定语从句。句意：然而，危险的环境和受损的道路将使食品和物资的运送变得困难，这意味着救援工作将面临巨大挑战。空处引导非限制性定语从句，对前面的句子进行补充说明，从句中缺少主语，应用关系代词which作引导词。故填which。 三、完形填空 【答案】 1．A 2．D 3．A 4．B 5．B 6．B 7．C 8．B 9．C 10．A 11．D 12．A 13．B 14．A 15．B 【导语】文章讲述了作者在洪水来临前做了准备，深夜被湍急水声惊醒后艰难逃生的惊险经历，并从中感悟到要铭记自己幸存下来的那一天。 1．考查动词。句意：那天早些时候，我为不太可能发生的洪水做了准备。A. prepared准备；B. waited等待；C. come来；D. shopped购物。根据下文“I’d

4．考查名词。句意：在我的朋友们离开之前，他们嘲笑我这样做，但我想，为什么要冒险呢？A. chance机会；B. risk风险；C. break休息；D. step步骤。根据上文“authorities had issued a flood ____, though not for where I was.”和“I’d placed on the floor outside my garden door in case of the flooding water.”可推知，尽管洪水预警并不针对作者所在地区，但作者还是做了一些准备工作，说明作者认为没必要“冒险”；take a risk意为“冒险”。 5．考查形容词。句意：午夜过后，我被汹涌的流水声惊醒，仿佛我躺在瀑布边而不是卧室里。A. occasional偶尔的；B. wild狂野的，汹涌的；C. natural自然的；D. faint微弱的。根据下文“as if I were lying beside a waterfall”可知，仿佛我躺在瀑布边,水声应该是“汹涌的”。 6．考查动词。句意：相反，水正从花园门的缝隙中喷射进来。A. clearing清理；B. shooting喷射，急速流动；C. gathering聚集；D. flowing流动。根据上文“as if I were lying beside a
