解析
【分析】
本题考查一般将来时中时间介词in和after的用法区别:in后接一段时间,用于一般将来时,表示“在……之后”;after后接具体时间点,可用于将来时或过去时。解题时需先判断每个空后的内容是“一段时间”还是“具体时间点”,再结合句子的一般将来时语境选择合适的介词。
【解析】
1. 空格后是“three days”(一段时间),句子为一般将来时,故用in;
2. 空格后是“two hours”(一段时间),一般将来时中用in表示“两小时后”,故用in;
3. 空格后是“4 o'clock”(具体时间点),故用after表示“在四点之后”;
4. 此处指科学展结束之后,属于时间相关的节点,用after;
5. 空格后是“5 pm”(具体时间点),故用after表示“下午五点之后”。
【答案】
1. in 2. in 3. after 4. after 5. after
【知识点】
时间介词、一般将来时
【点评】
本题聚焦基础时间介词的用法辨析,需掌握in接一段时间(将来时)、after接时间点的规则,属于易掌握的基础题型,只要理清时间类型即可正确作答。

解析
【分析】
要判断句子中单词用法是否正确,需明确英语中表示顺序的词first与firstly的用法区别:first可作形容词、副词,用于修饰动词、名词或引出步骤;firstly仅作副词,多用于强调逻辑顺序,不用于列举步骤或修饰名词。逐个分析句子:1. 句中first修饰动词短语gets up,作副词,用法正确;2. 列举步骤时应使用First而非Firstly,用法错误;3. 此处需形容词修饰名词step,firstly是副词,用法错误;4. First用于引出步骤开头,用法正确。
【解析】
1. 句子1中,first作为副词修饰动词短语gets up,意为“首先”,符合用法,故判断为√。
2. 句子2为列举步骤,英语中列举步骤常用“First, Second, Third...”结构,而非“Firstly”,故用法错误,需将Firstly改为First。
3. 句子3中,需形容词修饰名词step,firstly是副词,不能修饰名词,故用法错误,需将firstly改为first。
4. 句子4中,First用于引出步骤的开头,符合用法,故判断为√。
【答案】
1. √ 2. ×,Firstly改为First 3. ×,firstly改为first 4. √
