[单项选择] When student complete a first draft, they consider die job of writing done — and their teachers too often agree. When professional writers complete a first draft, they usually feel that they are at the start of the writing process. When a draft is completed, the job of writing can begin.
That difference in attitude is the difference between amateur and professional, inex perience and experience, journeyman and draftsman. Peter F. Drucker, the prolific (高产的) business writer, calls his first draft "the zero draft" —after that he can start counting. Most writers share the feeling mat the first draft, and all of those which follow, are opportunities to discover what they have to say and how best they can say it.

[单项选择]Question 1-10
All mammals feed their young. Beluga whale mothers, for example, nurse their calves for some twenty months, until they are about to give birth again and their young are able to find their own food. The behavior of feeding of the young is built into the reproductive system. It is a nonelective part of parental care and the defining feature of a mammal, the most important thing that mammals-- whether marsupials, platypuses, spiny anteaters, or placental mammals -- have in common.
But not all animal parents, even those that tend their offspring to the point of hatching or birth, feed their young. Most egg-guarding fish do not, for the simple reason that their young are so much smaller than the parents and eat food that is also much smaller than the food eaten by adults. In reptiles, the crocodile mother protects her young after they have hatched and takes them down to the water, where they will find food, but she does not actually feed them. Few insects feed their young
A. By storing food near their young.
B. By locating their nests or cells near spiders and caterpillars.
C. By searching for food some distance from their nest.
D. By gathering food from a nearby water source.
