解析与学生常见错误提醒
1. 参考答案:I do not like apples. / I don’t like apples.
解析:含有实义动词`like`的肯定句变否定句,主语是`I`,需借助助动词`do`,在其后加`not`。`do not`可缩写为`don’t`。
学生常见错误提醒:写成“I not like apples.” (缺少助动词) 或 “I no like apples.” (误用`no`)。
2. 参考答案:It is not a big elephant. / It isn’t a big elephant.
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“It not is a big elephant.” (语序错误)。
3. 参考答案:She is not a nurse. / She isn’t a nurse.
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“She not is a nurse.” (语序错误) 或 “She is no a nurse.” (误用`no`)。
4. 参考答案:问句:Is this a monkey? 肯定答:Yes, it is.

学生常见错误提醒:写成“This is a monkey?” (语序未变)。
5. 参考答案:问句:Can you see a flower? 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:Is he your father? 肯定答:Yes, he is.
解析:含有 be 动词`is`的肯定句变一般疑问句,将`is`提到主语`he`前面。`my`变成`your`。`he`回答用`he`。
