Unit 3 The world online 时间：30分钟 Ⅰ.单项填空 1．The Smiths can afford a large house with a garage ________. A．attached B．attaching C．to attach D．attach 答案 A [本题考查“with＋宾语＋过去分词”结构。attach和garage之间为被动关系，故要用过去分词。] 2．________ after a long walk，Tom called and said he couldn't come to the party. A．Having worn out B．Being worn out C．To be worn out D．Worn out 答案 D [过去分词短语作状语，表示原因。] 3．He gave up the way of life he had got accustomed to ________ to be independent. A．learning B．learn C．to learn D．to learning 答案 C [he had got accustomed to是定语从句，修饰先行词the way of life(作to的宾语)；因此要用to learn作目的状语，不要错选A。] 4．The advantage human beings can ________ the sun is worth researching. A．take of B．have on C．do with D．make of 答案 A [human beings can ________ the sun是定语从句，修饰先行词The advantage，能和advantage搭配的应是take of，构成词组是take advantage of，意思是“充分利用”，所以正确答案是A。] |
