双基限时练(十一) Unit 4 Part Ⅱ
Ⅰ.单句语法填空(不多于3个单词)
1．________ (seat) himself by a table, the gentleman asked the waiter for a cup of coffee politely.
答案与解析 Seating 句意：这位绅士在桌旁坐好后，礼貌地向服务生要了一杯咖啡。seat为及物动词，表示“使(自己)就座”，其逻辑主语为the gentleman，所以用现在分词形式。
2．The party will be held in the garden, weather ________ (permit)．
答案与解析 permitting 句意：如果天气允许，聚会将在花园中举行。逗号前后两部分的主语不同，由此可判断逗号后面部分是独立主格结构， weather与permit之间是主谓关系，所以用permitting。
3．I'm afraid we'll have to work extra hours, for there are still some problems remaining ________ (settle)．
答案与解析 to be settled 此处是分词短语作后置定语，remain与problems之间为主动关系，故应用现在分词形式；问题是亟待被解决，故应用to be settled。
4．To catch the first train, they went ________ (run) all the way.
答案与解析 running 该句中主语they与run之间存在主动关系，故用running做伴
