2. B。句子开头有It was…，如果去掉It was部分，余下部分是一个完整句子，判断这是强调句型。强调句的固定结构为It is/was…that/who...，答案为that。句意为：正是在我回家的时候我才意识到助人于危难中是多么令人高兴的事。
3. D。句意：当你正在看一个你喜欢的节目时，突然有个人进来，一声不吭地关掉电视，你会怎么想？it作形式宾语，指代if后面的句子。
4. A。根据句意：如果你去报摊上买今天的报纸，给我捎回一份好吗？one作“一个”，“一本”，“一件”等解，用来代替上文提到过的paper。相当于a copy of paper.
5. A。those= that ones，代指前面的many of the items，表示复数、特指，被of McDonald’s 修饰，符合语境。ones 表示复数、泛指，不符合语境。
6. D。所填词做使役动词make的形式宾语，真正宾语是to go for a walk，选D。
7. C。nor位于句首引起部分倒装，排除B、D；再根据句意“这并不是（关于）我的故事，它也不是故事的全部。我的故事的结局不同。”选代词it。故答案选C。
