题目内容
12．--How long can I the book？--For three weeks，but you can't it to others．（ ）
| A． | see； lend | B． | borrow； lend | C． | keep； lend | D． | lend； borrow |
分析 -这本书我能借多长时间？
-三周，但是你不能借给别人．
解答 答案：C；borrow，借入；lend借出；see看见；keep保留；根据句中信息How long can I…the book？和答语For three weeks，可知，上句中指的是借入，又因为是和how long连用，所以上句应该用borrow的延续动词keep，根据句中but you can't…it to others可知该空应填lend，意为借出；故选C．
点评 解答该题的关键是区分"borrow""lend""keep"等几个词的用法．
