有些表示情感的及物动词，有与bore类似的用法。如：interest, excite, surprise, amaze, frighten, astonish, move, inspire, touch, scare, disappoint, puzzle, worry 这类词的现在分词形式，为“令人……”;过去分词形式，为“感到……”。

表示“除了”的词或短语有：except; but; except for; besides; except that (when...) 等。
(1) except 和 but 都表示“除了……之外。没有”，二者大多数情况下可以互换；但在no, all, nobody, nothing, no one 等词后多用 but。No one knows our teacher's address except / but him. (排除him)
(2) besides 除……之外，还……，有附加性。What other foreign languages do you know besides English? (English与other languages都属于know的范围)

5. for example; such as
(1) for example“例如”，用来举例说明某一论点或情况。一般只举同类人或物中的“一个”为例，作插入语，可位于句首、句中或句末。可用for instance替换。For example, air is invisible. / His spelling is terrible! Look at this word, for example.
(2) such as “例如”，用来列举事物，一般列举同类人或事物中的几个例子。插在被列举的事物与前面的名词之间，as后面不可有逗号。Some of the European Languages come from Latin, such as French, Italian and Spanish.

代词it、one、that的用法与区别
One泛指，指代前面提到的那类人或物，用于指代可数名词，相当于a+名词单数，其复数形式ones前一般要有定语，否则就要用some.
That(those复数)即可指代不可数名词，表特指，相当于the+名词，后面经常与介词修饰语连用。 It指代上文出现的名词，表示同类同物，另外还可表示时间、距离、天气、还可指代人称代词，表示性别身份不明，可作形式主语，形式宾语，引导强调句式以及一些固定搭配，如：get it, catch it, make it.
例如：① I have lost my watch. I think I must buy one.我丢了只表，我想我必须再买一只。(代指上文指到的同类事物，但不指同一个)
② Where is my pen? Have you seen it?
我的钢笔不知弄到哪去了，你见了吗？(代指上文提到的同一事物) ③ The land of China is larger than that of America.
