解析与学生常见错误提醒
1. 参考答案:I am not happy.
解析:含有 be 动词`am`的肯定句变否定句,直接在`am`后面加`not`。`am not`没有缩写形式。
学生常见错误提醒:写成“I not am happy.” (语序错误) 或 “I don’t happy.” (误用助动词`don’t`)。
2. 参考答案:The soup is not too hot. / The soup isn’t too hot.
解析:含有 be 动词`is`的肯定句变否定句,直接在`is`后面加`not`。`is not`可缩写为`isn’t`。
学生常见错误提醒:写成“The soup not is too hot.” (语序错误)。
3. 参考答案:Emma does not feel tired. / Emma doesn’t feel tired.
解析:谓语动词`feels`是第三人称单数形式,肯定句变否定句需借助助动词`Does`,在其后加`not`,并将`feels`恢复为原形`feel`。`does not`可缩写为`doesn’t`。
学生常见错误提醒:写成“Emma not feels tired.” (缺少助动词) 或 “Emma doesn’t feels tired.” (助动词后动词未恢复原形)。

解析:含有 be 动词`is`的肯定句变一般疑问句,将`is`提到主语`it`前面。回答时用`it`。
学生常见错误提醒:写成“It is a circle?” (语序未变)。
5. 参考答案:问句:Can you see a star? 肯定答:Yes, I can.
解析:含有情态动词`can`的肯定句变一般疑问句,将`can`提到主语`you`前面。回答时主语`you`用`I`。

6. 参考答案:问句:Does Noah want to be a driver? 肯定答:Yes, he does.
解析:含有实义动词`wants`(第三人称单数形式)的肯定句变一般疑问句,需借助助动词`Does`,并将`wants`恢复为原形`want`。`Noah`是男孩名,回答用`he`。
