解析

【分析】
本题需结合每个句子的语境,从方框所给单词中选择合适的词,并根据句子结构、时态等要求调整单词形式。具体思路:1. 厨房着火对应“烟”,选smoke;2. 修饰名词action需形容词,选quick;3. 表时间“今晚”,选tonight;4. 固定搭配throw oneself into,结合时态用过去式;5. 表“安全规则”需名词作定语,选safety。
【解析】
1. 句意:厨房着火时有很多烟。smoke意为“烟”,是不可数名词,符合语境,故填smoke。
2. 句意:我们需要快速行动!叫救护车!此处修饰名词action,需用形容词quick,意为“快速的”,故填quick。
3. 句意:抱歉,我今晚不能和你一起看电影,我有点不舒服。tonight作时间状语,意为“今晚”,符合句意,故填tonight。
4. 句意:他太累了,扑到床上很快就睡着了。固定搭配throw oneself into意为“扑进”,由was可知时态为一般过去时,throw的过去式是threw,故填threw。
5. 句意:了解实验室的安全规则很重要。safety rules是固定表达,意为“安全规则”,此处用名词safety作定语修饰rules,故填safety。
