昨天我回家的路上，看见他正在和一个人谈话。
When I entered the room, I sawherwatching TV.

我经常看见他在教室里跳舞。

【拓展】
类似smell这种用法的词还有：feel(摸起来，感觉)；look(看起来)；sound(听起来)；taste(品尝)等。例如：
The food tastes delicious. 食物尝起来很美味。
I feel so happy today. Mum will buy me a new bike. 我今天很高兴，妈妈要为我买辆新自行车。
The blouse looks very beautiful. 那件衬衫看上去很漂亮。
3. But now you’d better go to see a doctor.
you’d better 是you had better的缩写。had better(常简略为’d better)是一固定词组，had better意为“最好”，用于表示对别人的劝告、建议或表示一种愿望。其用法有以下几点：
(1) had better后面必须跟动词原形，构成had better do sth.句型。
【注意】这里的had不能用have来替换。例如：
You’d better go to hospital at once.你最好立即去医院看病。
Tom, you’d better go there today.汤姆，你最好今天去那里。
(2) 主语不论是第几人称，句子不论是什么时态，都要用had better的形式。例如：
Now you(he; we) had better listen to the teacher.你(他，我们)现在最好听老师讲。
4. It not only disturbs others but also does great harm to people’s hearing.
(1) not only...but also的意思是“不但……而且……”，连接两个并列成分，如果连接两个主语的时候，谓语动词和also后面的主语保持一致。例如：
Not only my mother but also I like to go to the garden.不仅妈妈而且我也喜欢去公园。
(2) 以not only…but also 开头的句子往往引起倒装。例如：
Not only did he complain about the food, but he refused to pay for it.
他不仅抱怨饭不好吃，而且拒绝付饭钱。

something表示“阻止某人做某事或者阻止某事发生”。例如：

我们必须阻止他去河里游泳。
【拓展】stop的其他常用搭配：
stop doing sth. 停止做某事
stop to do sth. 停下来去做（另外）某事例如：
Let’s stop to have a break. 咱们停下来休息一会儿。
The two girls stopped talking when they saw me.
那两个女孩一见到我就停止了讲话。
Now let’s stop reading. 现在咱们停止读书。
Our teacher stopped to look at the boy. 老师停下来看了看那个男孩。
6. Would you like to be a greener person?
Would you like to do…？是询问对方的意见，邀请或请求某人做某事的一种委婉表达方法。其用法如下：
(1) 肯定句：
would like 后接名词或代词；would like to 后接动词原形，would 常和主语缩写为“主语＋’d”。 例如：
I’d like a cup of tea. 我想喝一杯茶。
He’d like to see a film. 他想看电影。
(2)否定句：
在would 后加not，意为不愿意做……，would not 缩写为wouldn’t。例如：
I wouldn’t like to go to the cinema. 我不想去看电影。
(3)疑问句：
把would 提到主语前即可。 例如：
Would you like to go to the cinema? 你愿意去看电影吗？
(4)答语：
