Answer 1

分析 这是一封和朋友交流集邮爱好的信．
我很喜欢你给我的邮票，我从八岁就开始集邮了，到现在已经有一千多张了，其中有四百多张外国邮票．集邮不仅可以让我欣赏到精美的设计，而且获得了许多知识．我们可以交换邮票，希望一辈子是朋友．

解答 Dear Susan，

                                                    Li Hua解析：
1．send-sending．考查非谓语动词．介词for 后用动名词做宾语，所以用sending．
2．what-how．考查感叹句．修饰形容词beautiful 用how，表示"这些邮票是多么漂亮"．what修饰名词．
3．liked-like．考查谓语动词的时态．根据上文可知"我喜欢这些邮票"，指的是现在的情况，所以谓语动词用一般现在时态．
4．in-at．考查介词．固定短语at the age of 表示"在某人多大的时候"．
5．collect ed前加have．考查谓语动词的时态．根据时间状语So far表示"到目前为止"可知谓语动词用现在完成时态，所以谓语动词用have collected．
6．interest-interesting．考查单词辨析．做I find stampcollecting 的宾补，修饰stampcollecting应该用interesting．表示"我发现集邮很有趣"．
7．many-much．考查不可数名词的修饰词．修饰不可数名词knowledge用much．
8．it-them．考查代词．代指上半句的stamps用them．
9．去掉the．考查冠词．可数名词复数stamps在这里表示泛指，所以去掉the．
10．friend-friends．考查名词复数．本句表示"希望两人成为朋友"，所以不是只有一个人，因此用复数friends．
