Ever since Gregor Mendel’s famous experiments with hybrid sweet peas, it has been known that there must be unitary elements within the cells which exert control over inherited characteiristics, and for a long time there was considerable speculation about what these were. These elements came to be known as genes, and although they were long treated as hypothetical constructs, a great deal of knowledge about them slowly accumulated. It came to be known, for example, that each gene had to be passed along virtually unchanged from generation to generation; that there must be many thousands of these particles in every human cell, distributed unevenly among the twenty-three pairs of chromosomes; that each gene must occupy a very definite place (locus) on its chromosome; and that each pair of homologous chromosomes had to contain homologous assortments of genes, arranged with few exceptions in precisely the same order on each member of the chromosome pairs.

第一篇
Motoring Technology
1.2 million road deaths worldwide occur each year,plus a further 50 million injuries.To
reduce car crash rate,much research now is focused on safety and new fuels一though
some electric vehicle and biofuel research aims at going faster.
Travelling at speed has always been dangerous.One advanced area of research in
motoring safety is the use of digital in-car assistants. They can ensure you don't miss
important road signs or fall asleep.Most crashes result from human and not mechanical
faults.
Some safety developments aim to improve your vision.Radar can spot obstacles in
fog,while other technology" sees through"big vehicles blocking your view.
And improvements to seat belts, pedal(脚踏)controls and tyres are making driving
smoother and safer.The colour of a car has been found to be linked with safety,as have,
less surprisingly, size and shape.
But whatever is in the fuel tank,you don't want a thief in the driving seat and there have
been many innovations(创新).Satellite tracking and remote communications can also
come into play if you crash,automatically calling for help.
Accidents cause many traffic jams,but there are more subtle interplays between
vehicles that can cause jams even on a clear but busy road.Such jams can be analyzed
using statistical tools.Robotic drivers could be programmed to make traffic flow smoothly
and will perhaps one day be everyone's personal chauffeur(司机),but their latest efforts
suggest that won't be soon.
According to the second paragraph,most road accidents happen due to
A.heavy traffic.
B.human mistakes.
C.engine failure.
D.bad weather.
