九年级英语 教学案unit2 1 人教版一、beside 只能作介词使用，意为“在旁边；和相比”。如： I keep a dictionary beside me when Im doing crosswords. 我填纵字谜的时候，手边总有一本字典。 Beside your earlier work this piece seems rather disappointing. 这件工作同你早先的工作相比，有些令人失望。 二、besides则有两种词性：介词和副词。1）当用作介词时，意为“除还”；或用于否定词之后，表示“除没有”。如： Besides knowing some reek, she was fluent in Italian. 她除了懂些希腊语之外，意大利语也说得很流利。 2）当用作副词时，意为“而且，此外”。如： Peter is our youngest child, and we have three others besides. 彼得是我们最小的孩子，我们另外还有三个孩子。三、except用于表示同类事物之间的关系，其意为除以外、除去。 1. except后面可接名词、代词、动词、副词、介词短语和从句等。如： We have an English lesson every day except Sunday. 除星期天外，我们每天有一堂英语课。(接名词) They all went to the park last Sunday except him. 除了他以外，上星期天他们都去公园了。(接代词) Every day Mary does nothing except watch TV. 每天玛丽除了看电视以外什么都不干。(except后接动词时，一般为带to的动词不定式。但如果except前面有谓语动词do或其相应形式时，后面通常接省略to的动词不定式。如此句。) He always goes to work by bike except recently. 除最近外，他一般都骑自行车上班。(接副词) After breakfast the students went nowhere except to school. 吃完早餐，学生们除了上学就不到别处去了。(接介词短语) My father usually goes to work by bike except when it rains. 除下雨天外，我爸爸通常骑自行车上班。(接从句) 2. except常用在all, whole, any, every, no等词，及anything, anybody, anyone, everything, everybody, everyone等不定代词之后。如： She ate everything on the plate except the carrots.除胡萝卜外她把盘子里的东西都吃了。 Ive cleaned all the rooms except the toilet. 除了厕所，我清扫了所有房间。 四、except for用于表示对主要部分的肯定和对局部的否定。它不表示同类事物之间的关系，意思为： 1. 除了以外。如： Smith is a good man, except for his bad temper. 史密斯除了脾气不好外，是个好人。 The movie was good except for the ending. 这部电影除了结尾之外都很好。 2. 除去为了。如： Mother wouldnt give him any money except for books and stationery. 除了买书和文具外，妈妈不给他任何钱。 3. 如果不是，若非。如： Except for you, I would pass the exam. 如果不是你，我就会通过考试。 4. except for+名词结构一般可以改写成except+that从句。如： This will do except for the length.= This will do except that it is too long. 如果不是它太长的话，这会很好。 All are here except for the absence of Tina. = All are here except that Tina is absent. 除了蒂娜以外，大家都在这里。 五、 except与except for的互换 1. except与except for有时可以通用，不过，一般情况下，except for可置于句首，而except则不能。如： Everyone is here except Tom. (或：Except for Tom everyone is here.)除汤姆外，大家都到了。 2. except与except for在句中也可互换。 一般来说，否定句中用except，肯定句式可以用except for来替换。如： This article has no blunders except a few mistakes.这篇文章除了一点小错外没有大错。 此句可改为：This article is instructive except for a few blunders. 这篇文章除了有些错误外，是有教育意义的。 不过，在前后有相称的同类词语时，应用except，否则用except for。如： We come to school every day except Sunday. 除星期天外，我们天天上学。(句中every day与Sunday同类) This dress is ready except for the buttons. 衣服做好了，只是钮扣未缝上。(句中ready与buttons不同类) 巩固练习： 用except, except for或besides填空1.
