難點(diǎn)四、現(xiàn)在進(jìn)行時(shí)
表示現(xiàn)在正在進(jìn)行的動(dòng)作 。

The boys are swimming across the river.
2. 疑問(wèn)句: 將be 動(dòng)詞移到句首

3. 否定句:在be 動(dòng)詞后面加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.

難點(diǎn)五、現(xiàn)在分詞的構(gòu)成
（1）一般動(dòng)詞加-ing 如：
look-looking, read-reading, play-playing
（2）以不發(fā)音的字母結(jié)尾的單詞去e 加-ing 如：
make-making, take-taking, arrive-arriving
（3）重讀閉音節(jié)詞結(jié)尾，即單詞中只有一個(gè)元音字母 ， 其后緊跟一個(gè)輔音字母的詞，雙寫(xiě)輔音字 母再加-ing 如：
run-running, sit-sitting, get-getting, swim-swimming, stop–stopping
規(guī)則四：以ie 結(jié)尾的動(dòng)詞 ， 把ie 改為y, 再加ing 。如： tie-tying, die-dying
難點(diǎn)六、Here is /are … 這兒有……
該句為倒裝句，真正的主語(yǔ)is/are 后面的部分 。is 后接單數(shù)：are 后接復(fù)數(shù) 。
Here is your book. 這是你的書(shū) 。
Here are your books. 這是你們的書(shū) 。
