British 3. studied 4. because 5. fewer 6. American 7. flying 8. exciting 9. to have 10. To 1. an 解析：exchange 是以元音音素 /ɪ/ 开头的单词，此处表示“一名交换生”，表泛指，故用不定冠词 an。 2. British 解析：空后为名词 friends，需用形容词修饰。Britain 是名词“英国”，其形容词形式为 British（英国的），此处表示“英国朋友”。 3. studied 解析：句首时间状语为 Last year（去年），提示句子时态为一般过去时，谓语动词 study 需用过去式 studied。 4. because 解析：前半句“He was also careful”（他也很细心）与后半句“he knew the more careful he was... mistakes”（他知道越细心，考试中犯的错就越少）之间是因果关系，后半句表原因，故填 because（因为）。 5. fewer 解析：此处为“the + 比较级，the + 比较级”结构，意为“越……，越……”。few 的比较级为 fewer，修饰可数名词 mistakes，表“更少的错误”。 6.
