19．Many lifestyle patterns do such __ great harm to health that they actually speed up __weakening of the
human body．（　　）
A．a；/B．/； theC．a； theD．/；/

分析 句意：許多生活方式對人類的健康有害，他們加速了人類身體的衰退．

解答 答案B．第一空為固定短語do harm to"對---有害"；中間無需冠詞，第二空后的weakening是動名詞，表示衰退，根據句意，這里是特指"人類身體的衰退"，所以用the表示特指，故選B．

點評 本題考查冠詞的用法，要掌握固定短語的用法如do harm to"對---有害"．

Hi Sharon，
This is Li Xia．I learned from your post that you want to improve your MandarmI am quite interested in it． I think I'm fit for it．As a student，I have been learning Mandarin for many years．In addition，I am Chinese，which means Mandarin is a must for me to communicate with others in my daily life． So I'm quite confident that I can help you learn Mandarin．
Learning Mandarin takes time，so if you want to learn it well，you should spend much time practicing Mandarin everyday．As the saying goes，practice makes perfect． Besides，you can also read some books in Chinese，see some Chinese films and listen to some Chinese radio programmes．Speaking and listening are very important for a language learning，by which you are sure to make great progress．
In your post，you say you can teach English as a reward．It is just what I want．I'm eager to improve my English．So，if you allow me to help you learn Mandarin，you can also help me improve my English．We can contact each other by video chat every night for half an hour in English and half an hour in Chinese，so that we can improve our oral speaking．
Hope for you early reply!
Yours Sincerely
Li Xia．
