The first time I heard(此处应用过去式) of Stephen Hawking, I was moving(moved,被……所打动,be moved by sth.) by his devotion to the research. As for his daily life, he is in greatly(great,此处修饰名词trouble应用形容词great) trouble. For example, only when he turns to the computer is it possible for him to speak, read and write. Therefore - However, his contributions for(to,对……做出贡献,contribution(s)后面的介词应该用to) the world have no equal. And, in my opinion, nothing could be rewarded(此处应用被动形式,reward sth. for把……当作奖励,sth.提前变为被动,sth. be rewarded for) for his contributions to science.
