几道英语用单词适当形式填空题目 求高手帮忙解答 在线等

1 How much __did _ this pair of jeans _cost__(cost)? 一般过去时态，所以用did
2__Don't_ (not tell) him the bad news,please 祈使句，否定时用don't
翻译 我对我们校篮球队昨天没能进入决赛感到纳闷
I_wonder why__ our school baskerball team _couldn't enter the final ___________ yesterday

1 、does； cost 由于主语中心词是this pair of jeans，所以应该用单数形式
2、 don't 祈使句的话，要用动词原形，省略主语。
3、wonder why；did't take part in the final match

1. does, cost (中心词是pair，而不是jeans)
2. Don't tell (祈使句的否定句是在动词原形前加don't)
3. felt puzzled, couldn't be in the final match

does cost pair 是单数，此题根据pair确定do的形式
Don't tell 祈使句的否定形式。
wondered \could,t be on the final
