    優(yōu)質解答
    此句中的to do 表示 動詞不定式,instructed sb to sth 告訴某人做某事
    動詞不定式(to do)可以作如下幾種狀語:
    1)目的狀語
    in order to do sth.
    so as to do sth.
    to do sth.
    2)程度狀語(也有說成表示程度的結果狀語)
    adj./adv.+ enough + to do sth.
    too + adj./adv.+to do sth.
    so + adj./adv.+ as + to do sth.(注意不要遺漏as)
    such + adj.+ a/an c.n.(單數)/c.n.(復數) + as + to do sth.
    3)出其不意/出乎意料的結果
    only/never + to do sth.
    I arrived at the station only to find the train had left.
    對比:預料之內的結果用分詞作狀語
    I slipped,breaking the vase.
    4)偶爾用作的條件狀語(高中不要求掌握)
    相對來說,動詞不定式作狀語的用法是較為簡單的.
    1由 too構成的短語
    too所構成的短語,常用的有如下一些:
    1)all too實在太(很),all too soon /quickly太早(太快).例如:
    The holidays ended all too soon.假期結束得太早了.
    2)none too一點也不.例如:
    We were none too early for the train.我們剛好趕上火車.
    3)only too極其,非常.例如:
    We shall be only too pleased to hear from you further.我們非常歡迎你再來信.(注意這里不是too...to...結構)
    The news was only too true.這消息是千真萬確的.
    4)quite too簡直太…….例如:
    It’s quite too surprising!這簡直太讓人吃驚了!
    5)rather too稍微……了一點.例如:
    The soup is rather too salty.湯稍微咸了一點.
    6)too...to...太……以至不能…….例如:
    The boy is too weak to lift the heavy box.這男孩太虛弱,舉不起那個重箱子.
    當too...to...跟少數形容詞(如ready,glad,pleased,apt,willing,inclined,eager,easy,satisfied等)搭配時,不定式無否定意義.例如:
    He is too ready to promise.他輕于許諾.
    Beginners are too apt to make mistakes.初學者極易出錯.
    He is too much inclined to give himself airs.他太喜歡裝模作樣了.
    需要注意的是,too...to...的否定形式nottoo...to...的意思是"不是太……而不能".例如:
    He is not too young to dress himself.他不是小得連衣服都不會穿.
    It is never too late to learn.活到老,學到老.
    在寫作時靈活運用這些短語,會使文章簡潔,含義清楚.這里要指出的是,在以上的這些短語中,too的含義是以"太,非常"為主.too還因此形成一類特殊而重要的用法,具體如下:
    2cannot(或can never)...too...表示"怎么……也不會過分"、"越……越好"的含義.如:
    1)One can never be too careful in one’s work.工作越細越好.
    2)One cannot be too careful in making the decision as it was such a critical case.因為這是一個如此重要的問題,所以在做出決定時無論怎樣謹慎都不過分.
    3)You cannot praise the play too highly.這出戲你無論怎樣稱贊都不會過分.
