8、我想：如果我能造出里面裝有機器的鋼筆，我就能寫得更快一些。 that has machine in it為定語從句，修飾a pen。定語從句的引導詞that，本身沒有意義，它的意義等同于被修飾的詞，本句中也可用which引導。本課中另一句：Thomas Edison said he liked people who had ideas. 此句也含有定語從句：who had ideas，被修飾的是people。被修飾的詞稱為先行詞，先行詞若指人，引導詞用who(m)，先行詞若指物，引導詞用which/that。 be able to表示“能，會”，有能力，要用有生命的名詞作主

23、如…”之意。 e. g. I think the book seems to be more a grammar than a dictionary. 我認為這本書看來與其說是一本字典，不如說是一本語法書。 當然，more…than可以表示“比…更…”之意。 e. g. This piece of advice is more useful than that one. 這條忠告比那條忠告更有用。 8. Don’t you think her radio is too loud? Yes, I do. 你覺得她的收音機聲音不大嗎？不，我覺得她的收音

24、機聲音太大了。 1）Don’t you think …? 是“你認為（覺得）…不…嗎？”之意，在think等詞引導的賓語從句中，如果要否定賓語從句，要將否定前移，翻譯句子時要把否定的意思放在think的賓語從句中。 e. g. —Don’t you think he is a naughty boy? —No, I don’t. 你覺得他不是個淘氣的孩子嗎？ 是的，我覺得他不是個淘氣的孩子。 I don’t think chickens can swim. 我認為雞是不會游泳的。 2）turn down是“（把開關
