介詞后面何時才能加動名詞形式對于考生來說一直是個糾結(jié)的問題，小編為此特意總結(jié)了一些關(guān)于to后面何時才能加ing的一些例題，希望對廣大考生有所幫助！　
    EX. I look forward to talking to you on Friday afternoon.
    例句：我期待下周五與你的談話。
    As the example above shows， sometimes it is correct to use “to” plus the –ing form of a verb.
    從例句里我們可以看到，有時“to”也可以加動詞-ing形式。
    Many non-native English speakers are reluctant to use –ing after “to”。 Maybe this is because you learnt at school that after “to” a verb should always be in the infinitive.
    許多非英語國家的人都不喜歡在“to”后面加動詞-ing形式。這可能是因?yàn)槟銈儗W(xué)校里的老師告訴你們“to”后面一般都跟動詞不定式。
    This is only half true. “To” actually has two uses – EITHER as an infinitive marker (e.g. The Company wishes to purchase the shares)， OR as a preposition (e.g. He has gone to lunch)。
    其實(shí)不然。事實(shí)上“to”有兩種用法，一種是動詞不定式的標(biāo)志(比如：這家公司想要收購股份。)，另一種，用作介詞。(比如：他去吃飯了。)
    When “to” acts as a preposition it is usually followed by an –ing form (which in this case is a gerund) or a noun/noun phrase， as in these examples：
    當(dāng)“to”作介詞時，后面通常會跟著動詞-ing形式(動名詞)或者名詞/名詞詞組，比如：
    EX1. There is no obstacle to registering the company.
    EX2. There is no obstacle to the registration of the company. 中 華 考 試 網(wǎng)
    例句：注冊這家公司沒有困難。
    EX1. I do not recommend committing yourself to purchasing the shares yet.
    EX2. I do not recommend committing yourself to the purchase of the shares yet.
    例句：我現(xiàn)在還不建議你去收購那些股份。
    EX1. I look forward to hearing from you.
    EX2. I look forward to your reply.
    例句：我期待你的回復(fù)。
    There are， of course， exceptions to this rule. The next post looks at these.
    當(dāng)然，“to”加動詞-ing也有例外的時候。敬請期待下次更新。
