      英语语法的学习是英语语言学习的基础,语法一直是高中英语教学的一个难点,那么高一必修一的英语你掌握了多少了呢?接下来小编为你整理了高一英语必修一知识点语法,一起来看看吧。

      高一英语必修一知识点语法:able用法

      1. 表示“有能力的”、“能干的”,可用作表语或定语。如:

      He is an able manager. 他是位有能力的经理。

      He is old but still able. 他虽年老,但仍有很能干。

      2. 用于 be able to do sth(能或会做做某事)。如:

      He is able to speak English. 他会说英语。

      Everyone here is able to type. 这儿的每一个人都会打字。

      He will be able to get about in a week or two. 再过一两个星期左右他就能走动了。

      He studied hard and was able to pass his examinations. 他学习很努力,所以考试及了格。

      注:be able to 不仅有多种时态形式(通常不用于进行时或与 be going to 连用),而且还可以与某些情态动词连用(通常不与 can 连用),甚至还可以有非谓语形式。如:

      Since his accident he hasn’t been able to leave the house. 自出事之后,他一直未能离开家。

      You might be able to persuade him. 你也许能够说服他。

      I hope to be able to do the work. 我希望能干得了这项工作。

      I regret not being able to help her. 我很遗憾未能帮助她。

      3. able 的比较级和最高级通常是 abler 和 ablest,也可以是 more able 和 most able,有时还可用 betterable和best able。如:

      You are better able to do it than I (am). 你比我更有能力做这件事。

      She’s the person best able to cope. 她是个最能妥善处理问题的人。

      4. 若要加强语气,其前除可very, quite, perfectly等修饰外,有时还可用well修饰。如:

      He is quite [well] able to take care of himself. 他完全有能力照顾自己。

      He’s a very able student; he’s just too lazy. 他是个很有能力的学生,只是太懒了。

      若受just, only just修饰,则表示“只能”“仅能”。如:

      I was just able to make out a dark figure in the distance. 我只能看见远处有个黑影。

      5. able的反义词是unable(不能的,不会的),不是disable,后者是动词,其意为“使残废”“使无能力”。比较:

      They were unable to reach a decision. 他们没法做出决定。

      Now that he was disabled, his house had become a prison to him. 因为他残废了,他的房子就成了他的牢笼。

      高一英语必修一知识点语法:admit用法

      一、表示“承认”

      1. admit一般为及物动词,直接跟宾语;表示向某人承认用介词 to。如: He admitted his mistake. 他承认了他的错误。

      He admitted to the teacher that he was wrong. 他向老师承认他错了。 This meant admitting defeat. 这就意味着承认失败了。 但有时也用作不及物动词,此时一般后接介词to。如:

      He admitted to the murder. 他供认了谋杀罪。

      He admitted to having taken the money. 他承认拿了那笔钱。

      由于 admit 表示“承认”可用作及物动词或不及物动词,所以上面各例中的介词 to 有时也可省略。

      2. admit

      She admitted having read the letter. 她承认读过这封信。

      I admit breaking the window. 我承认打破了窗子。

      3. admit可后接带不定式的复合宾语,但其中的不定式通常应是 to be。如: They admitted him to be mad. 他们承认他疯了。

      You must admit the task to be difficult. 你们得承认任务是艰巨的。 偶尔接其它形式的复合宾语。如:

      He admitted himself a failure. 他承认失败。

      He admitted himself beaten. 他承认输了。

      4. 有时用于插入语中。如:

      This, I admit, was wrong. 我承认这错了。

      二、表示“允许进入”“使能进入”

      1. admit通常只用作及物动词。如:

      This ticket admits one person only. 此券只准一人入场。

      There were no windows to admit air. 没有窗子可使空气流入。 可用于引申义,表示允许进入某一组织、机构、学校、团体等。如: They admitted him to [into] their organization. 他们接受他参加了他们的组织。 How many students have been admitted into the school this year? 今年这所学校有多少学生入学?

      试比较 (注意介词不同):

      He was admitted to [into] the Party. 他被吸收入党。

      He was admitted as a Party member. 他被接纳为党员。

      2. 往往含有动态意味,所以一般不与 enter, go in 之类的词连用。如:

      他打开门让我进了屋。

      正:He opened the door and admitted me into the house.

      误:He opened the door and admitted me to enter into the house.

      三、用于 admit of

      admit of为习语,意为“容许”“有……的可能”“有……的余地”(此时句子主语通常是物而不是人)。如:

      The matter admits of no delay. 这事刻不容缓。

      The word admits of no other meaning in the case. 这个词在此例中不可能有别的意思。

      四、两个派生词的用法

      1. admission n. 进入,入场 (不可数);承认 (可数,但通常只用作单数)。如: No admission without tickets. 无票不准进入。

      Admission to [into] the school is by examination only. 进入该校学习必须通过考试。 He made an admission that he was a thief. 他供认他是小偷。

      2. admittance n. 进入 (不可数)。有时可与 admission 互换,但不如 admission 常用。

      v.提供,供应得起,给予

      词形变化:

      动词过去式:afforded 过去分词:afforded 现在分词:affording 第三人称单数:affords

      例句与用法:
