任务型阅读。阅读下面短文，根据所给语境，按要求完成下列各题。

     When we compare ourselves with great people, we may feel very ordinary (平凡的) and unimportant.

However, we must remember that those great people were extraordinary (卓越的). The world has more

than 6 billion people, so it is difficult for all of us to be extraordinary. What can we do? We can try to be

the best people that we can possibly be.

     ①I think this means that we need to be honest and hard-working. We also need to be open-minded and

kind to other people. Most importantly, we need to be ambitious (有雄心的). We need to always set goals

for ourselves and work hard to achieve these goals.

     Madam Curie and Thomas Edison were hard-working, kind and ambitious, and they worked hard to

achieve their goals. Curie gave her life to"ease(减轻) human suffering". Edison spent his life as an inventor.

He invented a camera that showed movement. Later people used cameras to make modem films.

     A famous writer from Ireland once wrote,"We are all in the gutter (社会底层) but some of us are looking

at the stars." ②I often come up with this when I am unable to achieve something. It reminds me that we

are all at a lower level and that we all have a higher goal to work towards. It makes me try to be the best

person that I can possibly be.
