外研版八年级英语知识点

    鸟欲高飞先振翅，人求上进先读书。学习英语，需要把陌生的单词片语和句型语法不断的熟悉和熟练，使之成为我们的一种习惯。下面是小编给大家整理的一些八年级英语的知识点，希望对大家有所帮助。
    初二期末英语语法知识点总结归纳
    宾语从句
    结构：主语 + 谓语动词 + 宾语从句(主语 + 谓语动词 + 宾语/表语)
    1、引导名词性从句的连接词
    (1)that：没有含义，在宾语从句中不做成分
    (2)whether/if：表示是否，宾语从句中不做成分。
    (3)连接代词：what, which, who, whom, whose(在宾语从句中做主、宾、表和定语)
    连接副词：where, when, how, why(在宾语从句中做状语)
    2、在做宾语从句的题目时应注意时态
    (1)当主句是现在时态时，宾语从句可以根据需要使用任何时态。
    (2)当主句是过去时态时，宾语从句必须是一种过去的时态。
    (3)当表示客观事实或普遍真理的句子做宾语从句时，任何时候都用一般现在时。
    say/speak/talk/tell
    say：是最口语化的最普通的一个词，意为“说出”、“说道”，着重所说的话。如：
    “I want to go there by bus” , he said . 他说，“我要坐汽车到那里去。”Please say it in English .请用英语说。
    speak : “说话”，着重开口发声，不着重所说的内容，一般用作不及物动词 (即后面不能直接接宾语 ) 。如：Can you speak about him? 你能不能说说他的情况?I don’t like to speak like this. 我不喜欢这样说话。
    speak 作及物动词解时，只能和某种语言等连用，表达在对话中恰当使用词汇的能力。
    如：She speaks English well.她英语说得好。
    talk : 与 speak 意义相近，也着重说话的动作，而不着重所说的话，因此，一般也只用作不及物动词，不过，talk 暗示话是对某人说的，有较强的对话意味，着重指连续地和别人谈话。如：I would like to talk to him about it . 我想跟他谈那件事。Old women like to talk with children.老年妇女喜欢和孩子们交谈。
    tell : “告诉”,除较少情况外，一般后面总接双宾语。如：He’s telling me a story.他在给我讲故事。
    tell a lie 撒谎 tell sb. to do sth. /tell sb. not to do sth 如：.Miss Zhao often tells us to study hard.
