答案

解析

【分析】首先明确方框内单词的词性与词义:warn(动词,警告)、volunteer(名词:志愿者;动词:志愿)、alarm(名词:警报)、review(动词:复习;名词:复习)、thunder(名词:雷;动词:打雷)。接着逐句分析:1. 句中“loud”后需接名词,结合“rolling in the distance”(远处隆隆作响)的语境,确定对应“雷”,需用原形;2. “many”后接可数名词复数,结合“志愿服务”的语境,需将volunteer变为复数;3. “just now”是一般过去时的标志,需用warn的过去式;4. “alarm clock”是固定搭配“闹钟”,直接用原形;5. 主句用过去进行时(was+现在分词),结合“复习笔记”的语境,需用review的现在分词。
【解析】1. 句意:我们听到远处雷声隆隆。loud为形容词,后接名词,thunder(雷)符合语境且为不可数名词,故填thunder。2. 句意:许多志愿者在暴风雨后帮忙清理公园。many后接可数名词复数,volunteer(志愿者)的复数形式为volunteers,符合语境,故填volunteers。3. 句意:刚才警察警告司机在雨中慢行。just now是一般过去时的时间标志,warn的过去式为warned,故填warned。4. 句意:我的闹钟没响,所以我睡过头上学迟到了。alarm clock是固定短语“闹钟”,故填alarm。5. 句意:电话响的时候她正在复习笔记。when引导的时间状语从句,主句用过去进行时,review的现在分词为reviewing,故填reviewing。

解析

【分析】
首先明确方框内各短语的含义及用法:go off(警报等响起;出故障),by the time(到……时候,引导时间状语),out of breath(上气不接下气),as a result(结果),go wrong(出故障;出错)。再结合句子语境、逻辑关系及时态要求选择并调整短语形式:1. 冲出大楼后状态是上气不接下气,用固定短语out of breath;2. 表示“到雨停时”,用by the time,句首大写;3. 前后是因果关系,用as a result,句首大写;4. 停电时电脑出故障,由lost(过去式)可知用go wrong的过去式went wrong;5. 火警响起,由ran(过去式)可知用go off的过去式went off。
【解析】
1. 句意:地震期间他们冲出大楼,上气不接下气。out of breath是表状态的固定短语,符合语境,无需变形。
2. 句意:到雨停的时候,我们已经在里面待了几小时。by the time引导时间状语,表“到……时候”,置于句首首字母大写。
3. 句意:没人提前得到警告,结果很多人没准备。前后为因果逻辑,as a result表结果,置于句首首字母大写。
4. 句意:停电时我的电脑出故障,丢失了一些文件。由lost(过去式)可知时态为一般过去时,go wrong的过去式为went wrong,符合“电脑出故障”的语境。
5. 句意:火警响了,人们立刻跑向出口。go off可表示(警报器等)响起,由ran(过去式)可知用过去式went off,符合语境。
【答案】
1. out of breath 2. By the time 3. As a result 4. went wrong 5. went off
【知识点】
常用短语用法,一般过去时,介词短语
