Task：Some scientists believe intelligent life forms may exist in other

planets and some want to send messages to the space to contact with these life

forms. But other scientists believe it is a bad idea and it could be dangerous.

Discuss both ideas and give your own opinion.

Sample answer：

Since human beings have existed in the Earth for millions of years, some

scientists are curious about other intelligent forms in the universe. Some

scientists attempt to communicate with these life forms. However, others believe

it would be hazardous. In the following essay, both views will be explored as

well as my personal stance.

On one hand, many scientists and evidence has proved that humans are

definitely not the only creature in the universe, so contacting these

intelligent life forms could be demanding. Specifically, other life forms also

existed on other planets; some of them even have visited the Earth. For example,

about several decades ago, an UFO has visited a small town of America, and they

did not attack the humans. They could have destroyed the Earth if they had

despicable plans. Therefore, contacting with these unknown creatures could help

us to know the outer space better, so it would be beneficial for the humans to

try to contact with these aliens.

In stark contrast, some other scientists believe that contacting with life

forms would bring danger to the humans because we barely know them. To be

precise, some scientists believe that these intelligent life forms could be

smarter than us, and have more advanced technologies, people cannot win the war

if they invade the Earth. Take films as example, as it describes in Independence

Day, aliens invaded the Earth as they were aiming at the sufficient natural

resources on earth and it is totally for their own interest. Their attack caused

huge damage to the earth as human beings have no advanced weapon to fight

back.

In my opinion, even getting in touch with aliens could bring dangers to

humans, it is still worth trying as I believe the majority of them are seeking

for peace of the whole universe and hostility is barely carried. Looking for

other creatures in the vast universe is a big step for humans to explore the

outer space. It could be a double-sword, bringing both opportunities and

challenges. Whether aliens are dangerous dose not truly matter under this

circumstance, what is more important is that earthman, us, have the ability and

courage to take adventures in the unknown space and meet something new.
