Section A Directions:In this
section, there is a passage with ten blanks. You are required to select one word
for each blank from a list of choices given in a word bank following the
passage. Read the passage through carefully before making your choices. Each
choice in the bank is identified by a letter. Please mark the corresponding
letter for each item on Answer Sheet 2 with as ingle line
through the centre. You may not use any of the words in the bank more than
once. Questions 47 to 56 are based on the following
passage. To call something "marginal" means it is not
very good. Farmers have their own way to (47) marginal land:
It is the last to be planted under good conditions, and has the (48)
to be avoided under poor conditions. Low (49)
soil is not the only reason land could be considered marginal. It might be in an
area where rainfall is (50) or where a hillside might rise
too steeply(陡峭地). There are uses for marginal land, however.
Most often it is used as grassland. Grasses provide excellent (51)
for grazing (吃草) animals like cattle, sheep and goats. Grass seed can
be bought from a foreign supplier or (52) grasses can be
used. However, using marginal land for grazing is not a simple issue. There is a
(53) of overgrazing. Cattle can damage the crops by eating
down to the roots. Also, the weight of the animals crushes the soft and can make
it too hard for growing. A(n) (54) way to reduce the harm is
to move animals from one field to another. This method is known as rotational
grazing (循环放牧) which is extremely important for marginal land.
Another use for marginal land is for tree crops. Studies have
(55) that the white pine and loblolly pine (火炬松) are two
kinds of trees that grow well on such land. They grow fast and provide good
quality wood. Another tree is the poplar (白杨), found in many parts of the
world. Failure to take the care needed to protect marginal lands
can make a bad situation worse. But good planning can 56 a marginal
