基本上每个完整的句子都有一个动词，要表示第二个动作时可使用不定词、动名词、对等连接词、从属连接词或增加子句等方法连结。下面小编告诉你英语常用动词的用法，大家一起来看看吧!英语常用动词的用法：动词buy的四点小用法1. 用作动词，表示“买”，可带双宾语;若双宾易位，通常要用介词 for。如：我叔叔为我买了本英语词典。正：My uncle bought me an English dictionary.正：My uncle bought an English dictionary for me.2. 表示向某人买某物，通常用介词 from。如：He bought this watch from a friend. 他从一位朋友那儿买了这块手表。3. 表示用多少钱买某物，通常用介词 for。如：I bought the computer for $600. 我花600美元买了这台电脑。He bought it for very little money. 他买它只花了一点点钱。注：有时也用介词 at, 侧重指价格。如：He bought them for [at] 10p each. 他以每个10 便士的价格买下了它们。4. 是终止性动词，因此在肯定句中不宜与一段时间连用。如：这房子我已买了十年。正：I bought this house ten years ago.正：I have had this house for ten years.正：It’s ten years since I bought this house.误：I have bought this house for ten years.prepare的用法与搭配：1. 表示“准备”，可用作及物或不及物动词，用作不及物动词时，其后通常接介词 for。如：We must prepare (for) the party. 我们必须为聚会做准备。The children are preparing (for) their lessons. 孩子们正在预习功课。prepare sth 与 prepare for sth 的细微区别是：前者表示“准备……”，相当于 get sth ready, 常暗示所需时间较短;后者表示“为……作准备”，相当于 make preparations for, 常暗示所需时间较长。如：I’d better go upstairs and prepare her room. 我最好上楼去给她准备房间。We only heard about the meeting yesterday, so we haven’t started preparing for it yet. 我们只在昨天才听说开会的事，所以到现在还没有开始准备。2. 其后可接不定式，表示准备做某事。如：Have you prepared to go on a trip? 你准备好去旅行了吗?He prepared to write a novel about the war. 他准备写一本战争小说。3. 表示“准备”，可接双宾语，双宾语易位时用介词 for。如：She is preparing us a meal.=She is preparing a meal for us. 她在给我们准备饭菜。有时用人作宾语，表示使某人做好准备。如：We’ll prepare the child to face the difficulty. 我们要教孩子准备面对困难。They’re preparing the children for the examination. 他们在指导孩子准备考试。4. 用于be prepared，可用于以下结构：(1) be prepared to do sth：表示“准备做某事”“打算做某事”“愿意做某事”。如：I’m prepared to accept it. 我准备接受。How much is she prepared to pay? 他准备付多少钱?(2) be prepared for sth：表示“准备有某种情况”“防备某情况”。如：We were not prepared for the heavy rain. 我们没有提防要下这么大一场雨。(3) be prepared against sth：表示“对某种不好的东西作好准备”。如：We must be prepared against war. 我们必须备战。注意以下两句在含义上的差别：We are prepared to do it. 我们已准备好(或愿意)做此事。We are preparing to do it. 我们正在准备要做此事。decide的两个常用搭配：1. 表示“决定做某事”，其后要接不定式，不能接动名词。如：They decided to delay the meeting. 他们决定把会议推迟。She decided to call his office. 她决定给他办公室打电话。若要接动名词，应先接介词 on(但不如用不定式结构常见)。如：We decided on leaving. 我们决定离开。He decided on going abroad. 他决定出国。另外，decide on之后还可接名词或代词，表示“对……作出决定”或“选定……”。如：We haven’t decided on a price but we’re open to offers. 价钱未定，欢迎顾主开价。After seeing all the candidates we’ve decided on this one. 我们见了所有的候选人，决定选这位。2. 表示“决定不做某事”，可用 decide not to do 或 decide against doing。如：He decide not to change [against changing] his job. 他决定不换工作。They have decided not to move [against moving] to London. 他们已决定不搬到伦敦去。另外，decide against 之后也可接名词或代词。如：After talking the matter over, they decided against the plan. 经过反复讨论，他们决定不采用该计划。动词cause用法要点：要点一：表示“造成”“使(发生)”，注意以下搭配：①其后可直接用造成的结果或发生的事情作宾语。如：Smoking can cause lung cancer. 吸烟可导致肺癌。Careless drivers cause accidents. 司机不小心就出事故。②后接双宾语。如：The car caused me a lot of trouble. 这车给我引来了不少麻烦。I hope this will not cause you any inconvenience. 希望这不会给你造成不便。③后接不定式的复合结构作宾语。如：Heating a copper bar will cause it to expand. 对铜棒加热会使它膨胀。What caused your wife to change her mind? 是什么使你的妻子改变了主意?若双宾语易位，可用介词 to / for 来引出间接宾语。如：Her irresponsible behaviour has caused her family a great deal of anxiety.=Her irresponsible behaviour has caused a great deal of anxiety to [for] her family. 她不负责任的行为已引起她的家人的莫大担扰。要点二：表示“使”“迫使”，通常接不定式的复合结构作宾语，注意不要受动词 make 的影响而用错句型。比较：是什么使她哭了?正：What caused her to cry? / What made her cry?误：What caused her cry [crying]? / What made her to cry?这个坏消息使她伤心。正：The bad news caused her to be sad.正：The bad news made her sad.误：The bad news caused her sad.
