I still remember how nervous I am on my first day in
the new school three years ago,  while I found it difficult
to follow my teacher in the first English class. The teacher
spoke English throughout the class,  that was  totally
different from the lesson I have before.
In the morning class a next day,  the English teacher came to me
while I was reading the text loud like other
students. After listening to her for a while,  she gave me a big
smile and said she liked my voice very much. The smile shone on the
whole day and the following day.
A  week later on,  I volunteered to take charge of the English study in my class.
Thanks to the comforted smile,  I began to feel confident from then on. 		1. _____

单项选择题

The seventeenth-century physicist Sir Isaac Newton is remembered chiefly for his treatises on motion and gravity. But Newton also conducted experiments secretly for many years based on the arcane theories of alchemy, trying unsuccessfully to transmute common metals into gold and produce rejuvenating elixirs. If the alchemists of the seventeenth century had published the results of their experiments, chemistry in the eighteenth century would have been more advanced than it actually was.
Which one of the following assumptions would allow the conclusion concerning eighteenth-century chemistry to be properly drawn

A．Scientific progress is retarded by the reluctance of historians to acknowledge the failures of some of the great scientists.

B．Advances in science are hastened when reports of experiments, whether successful or not, are available for review by other scientists.

C．Newton’s work on motion and gravity would not have gained wide acceptance if the results of his work in alchemy had also been made public.

D．Increasing specialization within the sciences makes it difficult for scientists in one field to understand the principles of other fields.

E．(E) The seventeenth-century alchemists could have achieved their goals only if their experiments had been subjected to public scrutiny.
