七年级英语上册StarterUnit2知识点归纳（人教新目标）知识点解析一、主要句型1hat'sthisinEnglish?It'san“range”这个用英语怎么说?这是一个桔子。

2hat'sthatinEnglish?It'saap那个用英语怎么说?那是一张地图。

3Spellit,please-A-P请拼写一下。

-A-P。

二、重点难点分析1-hat'sthisinEnglish?这个东西用英语怎么说?-It'sanrange这是一个橘子。

初学英语的人心中肯定对很多英语单词或者表达方式不清楚。

当你想知道某个事物用英语如何表达时，你需要提问：hat'sthisinEnglish?比如你看到一杯牛奶，你想知道“牛奶”用英语怎么说，hat's“牛奶”inEnglish?那么hat'sthisinEnglish?如何回答呢?△-hat'sthisinEnglish?这在英语里怎么说?-It'saphne/aneraser是个电话/橡皮擦。

注意：答语中的phne和eraser是可数名词，因此前面要加上限定个数的定冠词a或an。

如果单词以辅音音素开头，就用不定冠词a。

如果单词以元音音素开头，就用定冠词an。

例如：ab一本书，aneraser一块橡皮。

inEnglish表示“用英语表达”，inhinese则表示“用汉语表达”。

hat's=hatis，hat用来询问某物是“什么”，is是be 动词一般现在时的第三人称单数形式。

this“这、这个”，是指示代词，而that表示“那、那个”，it“它”，是指物的人称代词。

anrange“一个橘子”。

an是不定冠词。

当单数可数名词以元音开头，则前面可以用不定冠词an;如果单数可数名词以辅音开头，则前面可使用不定冠词a。

如：aap一幅地图;aneraser一块橡皮擦。

不可数名词前一般不用不定冠词。
