【知识点】
1. 英语语法 - 冠词的使用：题目中的第一题涉及到冠词的使用。在英语中，conclusion前通常需要加不定冠词"a"，表示一个结论；而take the place of是固定搭配，意为“取代”，"the"在此表示特指。
2. 时间状语从句 - "before"的用法：第二题中的"How long will it be before..."句型询问的是在某个事件发生之前还要多久。根据上下文，这里指中国宇航员登上月球还需多长时间。
3. 动词短语辨析：第三题的"things don't work out as you expect"表示事情并未按照预期发展。"work out"在这里有"结果是"、"发展成"的意思。
4. 动词短语与分词作表语：第四题中，"remained seated"表示乘客保持坐着的状态，"seated"在此处用作形容词，修饰"passengers"。
5. 年代表达法：第五题考察了年代的表达，通常用"the 1950s"表示20世纪50年代，而"in his fifties"表示某人五十多岁。
6. 引导主语从句的"It is strange that + should + 动词原形"结构：第七题中的"It is strange that he should have escaped from punishment"表达了惊讶的语气，"should"在这里表示竟然。
7. 动词辨析与日常用语："attend the exhibit"意为参观展览，"roughly speaking"表示大约、粗略地说。
8. 形容词辨析："accessible"表示可接近的，此处指药品不会被孩子们轻易拿到。
