Answer 1

1.How much  2.pay，dollar  3.allowed
4.Did，use to  5.Why did

解析1．對價(jià)錢提問的用疑問短語多少前how much，故本題空格處填How much。
2．本題的含義為我在購買那本字典上付了10美元，pay……for可以表示支付的含義，故本題空格處填pay dollars。
3．改為被動(dòng)句，需將謂語動(dòng)詞改為be+動(dòng)詞過去分詞，故本題空格處填be allowed。
4．一般動(dòng)詞過去式改為一般疑問句在句首加did，后跟動(dòng)詞原形use，故本題空格處填Did，use to。
5．對原因提問的用why，后跟一般疑問句，本題為過去時(shí)，用助動(dòng)詞did，故本題空格處填Why did。
