Question

There is a tree near our house改为否定句

Answer 1

1.  解答: 这句话是there be句型，其否定形式是在be动词is后面加not，可以缩写成isn't。答案: There isn't a tree near our house.我们家房子周围没有树木。

2. 知识：英语陈述句变为否定句，一般是在动词后面加否定副词not，主要规则有一下几条：① 句子中包含动词be的，直接在be动词后面加not，一般是可以缩写的。比如aren't, isn't, wasn't, weren't 等等。 ② 句子中包含情态动词，直接在情态动词后面加not，可以缩写时应该缩写，比如can't，couldn't，needn't, mustn't, oughtn't 等等。③ 句子的谓语动词属于实义动词的，否定词not往往应该和句子的时态助动词结合，构成否定句，比如一般过去时didn't, 一般将来时won't，shan't，一般现在时don't, doesn't，现在完成时haven't, hasn't 等等。偶尔也有使用no构成否定句，但要明白：此时的no，相当于not a或者not any。

3. 例句：

   ① She was't good at English at that time. 那时，她英语并不好。

   ② I couldn't help giving him a hug when I see him for the first time. 第一次见到他，我禁不住和他拥抱在一起。

   ③ Tom always won't listen to his parents. 汤姆总是不听父母的话。
