同学你好~
“At present, China has already built roads spanning 19 thousand kilometers.”
“roads spanning 19 thousand kilometers” 表达略显中式，更地道的说法是 “has a road network totaling 19,000 kilometers” 或 “has constructed 19,000 kilometers of roads”。
在正式书面语中，千位分隔符更规范，建议写作 “19,000 kilometers”。
“Since 1990, there are 3.7 thousand kilometers road which would be newly built annually.”
“since 1990” 应使用现在完成时，描述从过去持续到现在的动作。
“road” 应为复数 “roads”。
可优化为：“Since 1990, China has been adding 3,700 kilometers of new roads every year.”
“Until 2020, the road framework will connect all important cities of China and the length of Chinese road will reach 55 kilometers, only next to America among the whole world.”
“Until 2020” 表示到 2020 年为止，但后文描述的是未来的状态，应使用 “By 2020”。
“55 kilometers” 明显错误，根据上下文应为 “55,000 kilometers”。
第二部分：
“condition” 应为复数 “conditions”。
“economic growth rate” 前应加定冠词 “the”。
“play the vital role” 应为 “play a vital role”。
第三部分：
“branches building” 应改为 “the construction of feeder roads”（支线公路建设）；“whole road projects” 应改为 “its overall road network development”。
“developmental opportunities bringing by” 应改为被动语态 “development opportunities brought by”。
“backbone road building” 应改为 “the construction of major trunk roads”。
希望对同学有帮助~
