D
I used to think education was the most
important thing in my life. Recently my attitude has begun to change, although
I still hold that it is essential for everyone in the world today. As a
top junior student in my college, I was asked to make a speech on how to learn
English well. Standing in front of the audience and facing so many freshmen, I
was trembling. I didn’t remember any word that I had prepared. I ran out of the
conference room without finishing my speech, leaving everyone puzzled. I cried
that night in my room, feeling that I was a loser. Studying takes up so much of
my time that I feel unable to really develop myself. I am just storing
knowledge, yet I fail to communicate with others. I have received many awards
in school, but they don’t necessarily reflect anything about me. I don’t know
how to socialize. When I leave school I fear I will be of no use to society.
I realize that everyone has his own way of
living. I want to change my lifestyle. Of course I will keep studying. Yet I
plan to look for a part-time job, which might turn out to be a good chance to
get to know society. I still believe that working my hardest makes me happy. I
will still stay on in college. But I will not allow it to shelter me from the
real world.

C
Africa is home to nearly 700 lakes and
rivers. It holds the largest amount of water on earth. Because of the overuse
of the lakes, natural climate changes and other factors(因素),
these lakes are disappearing quickly.
Millions of people in Africa depend on water
sources like lakes and rivers for their daily water. In other words, they
cannot live without these lakes and rivers. Recent studies by the United
Nations show that this loss of water supply is putting a great pressure on the
African population.
In the 1960s, Lake Chad was nearly 83,200
square feet large. In about forty years, it has lost 95% of its size and it has
almost completely dried up. At one time, it was one of the largest lakes in the
world, and was around 960,000 square feet around 6,000 years ago.
The sizes of lakes and rivers and the amount
of water have something to do with seasons naturally. But, pollution and
agriculture also play an important part in the loss of water. Many pollutants(污染物)are
put into lakes and rivers so that many lakes and rivers are seriously polluted,
and the water may be poisonous(有毒的).
If something isn’t done soon about the disappearing lakes and rivers, there
will not be enough water for everyone. Then many people in Africa will face
diseases and possible dehydration(脱水).
47. One way of soil conservation on flat,
open ground is ________.

_____.
A. there is a lot of sand
B. there is not enough water and salts
C. there is no water
D. the land is too hard
