The boys are swimming across the river.
2. 疑问句: 将be 动词移到句首

3. 否定句:在be 动词后面加not
We are not having lunch. He is not reading a book. The dog is not running after a cat.The boys are swimming across the river.
4. 特殊疑问句：what, which, how, where, who, etc.
疑问词＋动词＋主语＋现在分词

难点五、现在分词的构成
（1）一般动词加-ing 如：
look-looking, read-reading, play-playing
（2）以不发音的字母结尾的单词去e 加-ing 如：
make-making, take-taking, arrive-arriving
（3）重读闭音节词结尾，即单词中只有一个元音字母，其后紧跟一个辅音字母的词，双写辅音字母再加-ing 如：
run-running, sit-sitting, get-getting, swim-swimming, stop--stopping
规则四：以ie 结尾的动词，把ie 改为y, 再加ing 。如： tie-tying, die-dying
难点六、Here is /are ... 这儿有……
该句为倒装句，真正的主语is/are 后面的部分。is 后接单数：are 后接复数。
Here is your book. 这是你的书。
Here are your books. 这是你们的书。
