上述句子中worry要加about吗?它既是不及物又是及物动词,第二是thus那个结果状语用得对吗?
2、If those students haven’t been given those chances,they should have still worked with what they dislike and still didn’tknow what they live for.
3、if Da Vinci（达尔文） had just learned one subject such as drawing,he would not have been known as widely astoday.

例子：

You worried your mother by not writing. （你不写信回来,让你妈妈担心了.）

My mother always worries about me.  （我妈妈老是为我操心.）
