Language Points
1.I hear water running in the bathroom.我聽(tīng)到浴室里水在流淌。
hear此處作及物動(dòng)詞，意為“聽(tīng)見(jiàn)，聽(tīng)說(shuō)”，后可跟名詞、代詞、動(dòng)詞不定式（省to）、動(dòng)詞-ing形式或賓語(yǔ)從句。
e.g.:I can hear someone knocking at the door.
She couldn't hear what I said.
【辨析】hear sb. doing sth.與hear sb. do sth.
hear sb. doing sth.意為“聽(tīng)到某人正在做某事”，強(qiáng)調(diào)聽(tīng)見(jiàn)的動(dòng)作正在進(jìn)行。
e.g.:I heard him singing when I walked past the shop.
hear sb. do sth.意為“聽(tīng)到某人做了某事”，強(qiáng)調(diào)聽(tīng)見(jiàn)的動(dòng)作發(fā)生的全過(guò)程，表示此動(dòng)作經(jīng)常發(fā)生或動(dòng)作已經(jīng)完成。
e.g.:I often hear her sing in the evening.

語(yǔ)法拓展
情態(tài)動(dòng)詞表示推測(cè)的用法
一、表示不同時(shí)態(tài)的推測(cè)結(jié)構(gòu)。
“情態(tài)動(dòng)詞+do sth.”表示對(duì)現(xiàn)在事情的推測(cè)；“情態(tài)動(dòng)詞+be doing sth.”表示對(duì)正在發(fā)生的事情的推測(cè)；“情態(tài)動(dòng)詞+have done sth.”表示對(duì)過(guò)去或已完成事情的推測(cè)。
e.g.:He may have watched TV last night.
二、肯定推測(cè)。
1.must用于肯定句，表示較有把握的推測(cè)，意為“準(zhǔn)是，一定”，后接動(dòng)詞原形，表示對(duì)現(xiàn)在的推測(cè)。
e.g.:You must be exhausted.
2.may用在肯定句中，表示對(duì)現(xiàn)在把握不大的推測(cè)，意為“也許，可能”。
e.g.:It may be a new invention.
3.could,might也表示推測(cè)，常用在過(guò)去時(shí)中；但在某種巧合下，為了使語(yǔ)氣更緩和、更委婉，常用could,might代替can,may。
e.g.:They saw something in the sky last night.It could/might be a UFO.
4.can用于肯定句中，表示理論上的可能性。
e.g.:Smoking can cause cancer.
