[语篇解读] 本文为记叙文。汤姆和彼得是双胞胎兄弟，他们虽然长得很像但在学习态度上却迥然不同。
1.解析：此处应用虚拟语气，主句谓语动词look与as if从句谓语动词be没有先后顺序，故设空处用were。
答案：were
2.解析：句意：人们认为如果彼得像汤姆那样努力学习，在学习上他会和汤姆一样好。根据句意可知if从句为表示与现在事实相反的虚拟语气，故答案为worked。
答案：worked
3.解析：suggest作“建议”讲，后面宾语从句的谓语动词需用“should+动词原形”，其中should可以省略。
答案：(should) finish
4.解析：本句中的insist意为“坚持认为”，故用陈述语气。当insist作“坚决要求”讲时才用虚拟语气，即其宾语从句的谓语动词为“should+动词原形”，should可以省略。
答案：is
5.解析：wish后的宾语从句是与现在事实相反的虚拟语气，故填were。
