一、阅读理解
Pollution’s great effects on the environment have become more obvious in recent years,
leading to a movement to promote energy efficiency（效率）,less reliance on fossil（化石) fuels, and a reduction in air and water pollution. Most scientists agree that such changes
are necessary to protect our environment from further harm.
The construction industry consumes a large quantity of energy and resources and creates
a huge amount of pollution. In the United States, building and development account for 39%
of the country’s total energy use, 12% of total water consumption,68% of total electricity
consumption and 38% of carbon dioxide emissions（二氧化碳排放）, according to the Environment
Protection Agency.
Green buildings use less energy, water, create less waste, and are healthier to live,
work, and go to school in than standard buildings. Builders of green buildings use techniques

Be Careful about Cloning
After a series of initial experiments and corrections, the scientist’s hard work paid off when the
twin clone turkeys were hatched with normal feather and claws. This breakthrough possibly enabled people
to bring their adored pets back to life. However, it bothered him from time to time that their health
was in poor condition because they were unable to resist illnesses. This drawback cast him down. Merely
2 weeks later, the clones and their carrier died, which struck frustration into his heart. He retired
before he attained his ambition and became a member of an opera chorus to relieve his depression.
Shortly afterwards, the media published a conservative argument objecting to cloning owing to moral
problems, and suggested the constitution include compulsory regulations to forbid obtaining commercial

Sometimes, you just can't help it. Maybe you're watching a sad movie, or thinking about
the friend who moved away. Next thing you know, there's a lump in your throat, your eyes
are watering, and you have tears running down your cheeks.
A professor of psychology at Tilburg University, in the Netherlands,has studied
crying.According to Vingerhoets, there're three types of tears. Basal tears are the first
type. They act as a protective barrier between the eye and the rest of the world.Next
are reflex tears. They wash your eyes clean when something gets in them. Finally, there're
emotional tears. “These are released in response to emotional states,” explains
Vingerhoets.
Scientists believe crying has something to do with how humans developed and learned
to depend on each other. “Humans are very complex social creatures,” says Lauren Bylsma,

a blood vessel bursts in the brain.An aneurysm is a bulge in a blood vessel
that can burst.If that happens in the brain，it can be deadly.For survivors，physical disabilities are often severe.They may include memory problems，loss of balance，trouble speaking and even blindness.But new technologies
are increasing survival rates and reducing disabilities.

Chinese scientists recently have produced two monkeys with the same gene, Zhong
Zhong and Hua Hua, using the same technique that gave to Dolly the sheep. These
monkeys are not actually the first primates(灵长类) to be cloned. Another one
named
Tetra was produced in the late 1990s by embryo(胚胎) splitting, the division of an
early－stage embryo into two or four separate cells to make clones. By contrast,
they were each made by replacing an egg cell nucleus(细胞核) with DNA from a
differentiated body cell. This Dolly method, known as somatic cell nuclear
transfer(SCNT), can create more clones and allows researchers greater control over
the edits they make to the DNA.
Success came from adopting several new techniques. These included a new type
