the best scores on every single test, it was his highly/high scores on the psychological tests that he finally won him the status of China's first astronaut.

1.第一个was后加a　考查冠词的用法。"一个年轻的男孩",可数名词boy前用不定冠词a。

2.第一个his→whose　考查定语从句。关系代词whose在从句中作定语并引导定语从句。

3.goes→went　考查时态。根据上下文可知要用一般过去时。

4.from→in　考查介词。在具体的某一年用介词in,固定搭配graduate from意为"从......毕业"。

5.that→which　考查非限制性定语从句。which指代Project 921,不能用that引导非限制性定语从句。

6.selecting→selected　考查非谓语动词。v.-ed形式作后置定语。

7.but→and　考查连词。上下文之间不是转折关系,而是顺承关系。

8.test→tests　考查名词的单复数。由前面的all kinds of可以推知,指的是"各种各样的考试"。

9.highly→high　考查形容词。形容词作定语。his high scores指的是"他所得的高分"。

10.去掉he　考查强调句型。本句强调主语his high scores on the psychological tests。谓语动词是won,所以he是多余的。
