Some countries have spent a large amount of money in bicycles.
Why has this happened? Is it the best way to solve traffic problems?
混合文题型，问原因和同意与否。老话题，和交通堵塞相关
【段落示范】
【原因-社会层面-接上周内容】
1. Besides, the whole society will also be benefitted as traffic congestion and air pollution can moderately be alleviated.
接上周内容，总起句总写原因：对【个人】和【社会】都有好处。原因2就写【社会】层面好处：交通堵塞 & 环境问题得以缓解。
2. More accurately, once bicycles are accessible everywhere, individuals are more likely to, when the distance is not so long, ride a bike instead of driving private cars especially to the crowded downtown area during peak hours.
原因1(个人层面)：自行车更容易获得后，大众更可能选择骑车为出行方式去拥挤区域，尤其在高峰期。
3. In this case, the number of vehicles on road diminishes, thus reducing the emissions of exhaust.
路上车辆减少(对应前文的交通堵塞缓解)，排放减少(对应环境问题缓解)。
【解析】
1. 内容(Task Response)*** 特别重要 ***
见文中批注。
2. 组织(Coherence and Cohesion)*** 尤其重要 ***
见文中批注。
3. 词汇(Lexical Resource)
congestion为不可数名词，意思是“(交通)堵塞”。归类于“话题高频词”。
alleviate为及物动词，意思是“缓解”。归类于“通用词”。
accessible为形容词，意思是“易获得的”。归类于“通用词”。
peak hours为名词词组，意思是“高峰时段”。归类于“话题高频词”。
diminish 为不及物动词，意思是“减少，降低”。归类于“通用词”。
exhaust为不可数名词，意思是“(引擎排放的)废气”。熟词生用。归类于“话题高频词”。
4. 语法(Grammatical Range and Accuracy)
第2句：once引导时间状语从句 + individuals are more likely to ride a bike 为主句(中间有when引导的时间状语从句作插入信息)
第3句：thus reducing the emissions of exhaust 为 v.ing作结果状语，表示主句这件事自然而然导致的结果，v.ing对应的主语为主句这件事，相当于which will reduce, which 指代主句这件事。v.ing作【伴随状语】时，动词的主语对应【主句主语】，试对比：
The general public are more willing to take public transport, leaving their cars in garages. (be willing to take & leave对应的主语都是the general public.)
