Good morning，everyone，
I am Li Hua from Xingguang Middle School．The topic of my speech is"Let's Ride Bicycles"．As is known to us，air pollution and heavy urban traffic are becoming increasingly severe mainly due to the overuse of cars．Therefore，it's high time we chose another better means of transport that is，cycling．
There are many good reasons to ride bicycles．First of all，compared to cars，bicycles are much cheaper to buy and maintain，and you don't have all the added costs of fuel，and parking．What's more，bicycles are more environmentally friendly than cars，because they hardly make noises and exhaust．Cycling has become a new trend around the world，a good way of energy saving and low-carbon life．Last but not least，cycling is an excellent way to keep fit and live longer．By riding bicycles，you can cut down your risk of heart attacks，high blood pressure and other illnesses．So I think，riding bicycles actually has great effects on us．Let's ride bicycles from today on!
Thank you!．

Answer 1

分析 這是一份演講稿．根據(jù)題目要求可知用第一人稱和一般現(xiàn)在時(shí)態(tài)．內(nèi)容包括：一自我介紹，說明目前汽車帶來的空氣污染和交通阻塞等問題；二騎自行車的益處，如節(jié)能環(huán)保、有利健康等．
高分句型：
1．As is known to us，air pollution and heavy urban traffic are becoming increasingly severe mainly due to the overuse of cars．句子里．As引導(dǎo)非限制性定語從句 is known to us，表示"正如我們所知"；due to 表示"由于"．
正如我們所知，由于汽車的過渡使用，空氣污染和交通阻塞正在變得越來越嚴(yán)重．
2．Therefore，it's high time we chose another better means of transport，that is，cycling句子里固定句式it's high time 表示"該做某事了"，從句 we chose another better means of transport y用一般過去時(shí)態(tài)表示虛擬；that is表示"也就是說，即"．
因此是我們選擇另外一種交通方式的時(shí)候了，即，騎自行車．
