( y5 A: {0 g; k- g, e: q9 L; M　　答案及解析:
1 H7 ?. s) y. d8 }0 P　　1.surrounding－surroundings
　　surroundings作为名词总是以复数形式出现，surrounding是形容词。
: ^3 }, @4 o- M: [+ S) B　　2.board－aboard；^board－on
4 y6 [# j$ _6 r0 A3 Z/ P　　be abroad a train ( a ship, a plane…)意思是“在火车（船、飞机）上”。board 是名词，可以说be on board （这个改错之前也出现过，经常出现的大家可都要记住啦）
& v" t$ [/ H( b& {3 d; P　　3.you－yours
　　物主限定词your不能作介词的宾语，应该用物主代词yours。
　　4.interpret－interpreting
　　Interpret 通过and 和matching并列，所以也应该是进行体形式。
% `4 N- z* Z9 Q9 [/ f　　5.might－must
　　根据上下文，这里必须用表达非常肯定的语气must，而不是不肯定的“might”，而且，后面的not the other也强调了非此即彼的肯定性。
7 J5 ~! V0 ?$ ?' E　　6.are^－of
" O5 S5 k; h5 h' Q5 K  B; R8 X　　加上介词of作主语补足语表示对主语的某一种性质的描述。
　　7.burnt－burning
　　如果用过去分词burnt修饰candle，那么是说“十英里之外燃尽的蜡烛”，那是不可能用肉眼看到的，所以应该改成burning，表示“在燃烧的蜡烛”。
　　8.Colorful－Color
　　Colorful是指所修饰的事物本身具有明亮的或者不同的颜色，而color作定语是指修饰的事物使别的事物的各种颜色能够展现出来，而不是仅仅看到黑白两色，比如：color television，color photo，color picture等。
8 f4 m0 Z6 t# u3 i! G' q　　9.the－a
　　the third 表示顺序排列，和the first， the second 对应，“a third”表示数量上的增加，和one，another相对应。
　　10. that－those
　　data这个词是datum的复数形式，所以应该用those修饰
