Passage 4
Cloning shakes us all to our very souls. For humans to consider the cloning of one another forces them all to question the very concepts of right and wrong that make them all human. The cloning of any species, whether they be human or non-human, is wrong. Scientists and ethicists alike have debated the implications of human or non-human cloning extensively since 1997 when scientists at Roslin Institute in Scotland produced Dolly. No direct conclusions have been drawn, but compelling arguments state that cloning of both human and non-human species results in harmful physical and psychological effects on both groups.
The possible physical damage that could be done if human cloning became a reality is obvious when one looks at the sheer loss of life that occurred before the birth of Dolly. Less than ten percent of the initial transfers survive to be healthy creatures. There were 277 trial implants of nuclei. Nineteen of those 277 were deemed healthy
A. Animals will no longer be savage.
B. Humans will be as savage as animals.
C. A clear line will be missing between humans and animals.
D. Animals will have to be given fights of citizenship.

All of us communicate with one another nonverbally, as well as with words. Most of the time we’re not aware that we’re doing it. We gesture with eyebrows or a hand, meet someone else’s eyes and look away, shift positions in a chair. These actions we assume are random(随意的) and incidental. But researchers have discovered in recent years that there is a system to them almost as consistent and comprehensible (可充分了解的) as language.
Every culture has its own body language, and children understand its meanings along with spoken language. A Frenchman talks and moves in French. The way an Englishman crossed his legs is nothing like the way a male American does it. In talking, Americans are apt to end a statement with a droop(垂下) of the head or hand, a lowering of the eyelids(眼皮). They wind up(结束)a question with a lift of the hand, a tilt(倾斜) of the chin or a widening of the eyes. With a future-tense verb they often gesture with a forward movement.

A. communication between human beings is usually dull
B. the smallest words are best in effective communication
C. communication without body language would be dull
D. words are not important in communication
