[单项选择]The first technological revolution in modern biology started when James Watson and Francis Crick described the structure of DNA half a century ago. That established the fields of molecular and cell biology, the basis of the biotechnology industry. The sequencing of the human genome nearly a decade ago set off a second revolution which has started to illuminate the origins of diseases.
Now the industry is convinced that a third revolution is under way: the convergence of biology and engineering. A recent report from the Massachusetts Institute of Technology says that physical sciences have already been transformed by their adoption of information technology, advanced materials, imaging, nanotechnolugy and sophisticated modelling and simulation. Phillip Sharp, a Nobel prize-winner at that university, believes that those tools are about to be brought to bear on biology too.
But the chances are that this will take time, and turn out to be more of a reformation than a revolution.

B. He will brainstorm on it and try to cure the patient.
C. He will resort to the deterministic science of genomics.
D. He will freeze the case and wait for new cures to deal with it.

[不定项选择题]共用题干
第一篇
Sleepless at Night
It was a normal summer night. Humidity(湿气)hung in the thick air.
I couldn't go to sleep,partly because of my cold and partly because of my expectations
for the next day.My mum had said that tomorrow was going to be a surprise.
Sweat stuck to my aching body.Finally,I gathered enough strength to sit up.I looked
out of my small window into the night.There was a big bright moon hanging in the sky,
giving off a magic light.
I couldn't stand the pressure anymore,so I did what I always do to make myself feel
better. I went to the bathroom and picked up my toothbrush and toothpaste.I cleaned my
teeth as if there was no tomorrow.Back and forth,up and down.
Then I walked downstairs to look for some signs of movement,some life.Gladiator,
my cat, frightened me as he meowed(喵喵地唱出)his sad song. He was on the old
orange couch(长沙发),sitting up on his front legs,waiting for something to happen. He
looked at me as if to say, "I'm lonely, pet me. I need a good hug(紧抱)."Even the
couch begged me to sit on it.
In one movement I settled down onto the soft couch.This couch represented my
parents' marriage,my birth,and hundreds of other little events.
As I held Gladiator,my heart started beating heavily.My mind was flooded with
questions:What's life?Am I really alive?Are you listening to me?Every time I moved my
hand down Gladiator's body,I had a new thought;each touch sang a different song.
I forgot all about the heat and the next day's surprise.The atmosphere was so full of
warmth and silence that I sank into its arms.Falling asleep with the big cat in my arms,I
felt all my worries slowly move away.
Gladiator was the name of
A.a movie.
B.apet.
C.a couch.
D.asong.
