Good evening, ladies and gentlemen. The
lead story in tonight’s news concerns the fire which destroyed the major part
of Columbia College at 4 a.m. this morning. In only five minutes, more than six
hundred girls came out of their dorms to watch their college burn to the ground
in the freezing December weather. Fortunately, there were no injuries resulting
from the fire. According to the college president, plans are already made to
raise more than three million dollars to rebuild the college.
Here is the news from Washington. President
Clinton says he is troubled by a scientist’s desire to clone a human and is
urging Congress to pass a ban (禁令) on such experiments for at least five years. In his weekly radio
address, Clinton noted Chicago-area physicist Richard Seed’s announcement that
he is ready to set up a clinic to clone human babies. President Clinton said
that the need for passing laws that would ban human cloning for at least five
years is more urgent than ever.
