2. I want to use the same tools _______used in your factory a few days ago.

3. Is _______ some German friends visited last week?

4. I have bought two ball pens, _______ writes well.
A. none of them B. neither of them C. neither of which D. none of which
5. All that can be eaten _______ eaten up.
A. are being B. has been C. had been D. have been
答案解析：
1. D. 主句中的two表明不能選A.從句中的are表明不能選B. both of which用來引導非限制性定語從句.
2. C. as引導定語從句時通常構成such…as或the same…as固定搭配，其中such和same修飾其后的名詞，as為關系代詞，指代其前的名詞引導定語從句。as在從句中可以作主語、表語或賓語。本題中as作從句的主語.
3. B. 為便于理解，改寫本句話：This is the school that some German friends visited last week. 不難看出，作表語的the school是先行詞。that引導了定語從句，因為that同時又作visited的賓語，所以被省略了。其它選項結構不對。
4. C. 因為是two ball pens, 并且定語從句的謂語writes是單數概念。因此，C是正確選項。
5. B. 本句話中，主句的主語是all, 為抽象概念。因此，其謂語應用單數的has been。關系代詞that引導定語從句，并在從句中作主語。
