Part III Reading comprehension
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 a single line through
the centre. You may not use any of the words in the bank more than once.
Questions 36 to 45 are based on the following passage.
It was ten years ago, on a warm July night, that a newborn lamb took her first breath in a
small shed in Scotland. From the outside, she looked no different from thousands of other sheep
born on ___36__ farms. But Dolly, as the world soon came to realize, was no __37__ lamb. She
was cloned from one cell of an adult female sheep, ___38___ long-held scientific dogma that had
declared such a thing biologically impossible.
A decade later, scientists are starting to come to grips with just how different Dolly was.
Dozens of animals have been cloned since the first lamb—mice, cats, cows and most recently, a
dog—and it’s becoming ___39___ clear that they are all, in one way or another, defective.
It’s __40__ to think of clones as perfect carbon copies of the original. It turns out, though,
that there are various degree of genetic ____41___. That may come as a shock to people who have
paid thousands of dollars to clone a pet only to discover that the baby cat looks and behaves
___42___ like their beloved pet—with different color coat of fur, perhaps, or a __43___ different
attitude toward its human hosts.
And these are just the obvious differences. Not only are clones ___44___ from the original
template (模板) by time, but they are also the product of an unnatural molecular mechanism that
turns out not to be very good at making ___45___ copies. In fact, the process can embed small
flaws in the genes of clones that scientists are only now discovering.
