The water we drink and use was running short. We all have to learn what to stop wasting water.
One of the step that we should take is to find ways of reusing it. Today in the most large cities, fresh water is used only once and then it runs in waste system. But that is possible to pipe the used water to a purifying factory, there the used water can be treated with chemical materials by the workers so that it can reused. But even if every large city purified and reused it's water, we still would have enough water.
The First Americans
There was a time long ago when a land bridge connected Asia and North America. The first settlers in North America crossed this land bridge from what is now Siberia to Alaska. The people who made this initial(最初的) crossing were probably following the animals they used for food. Eventually, the oceans rose and the land bridge between the continents disappeared. The settlers, who I shall call the “First Americans”， could not return to their homeland. _1.__
For the next few thousand years, the First Americans migrated（迁徙） south and east throughout North and South America. They made the journey all the way from Alaska to the southern tip of South America, a distance of more than 10, 000 miles. __2.__In the far north, above the Arctic Circle, the First Americans became hunters of the ocean. __3.__ In the brief summer，they gathered berries and other plants. In the winter, they stayed in lodges much of the time preparing for the next summer. It was a hard life，but they learned to survive in these harsh conditions.
Farther south, in what is now Arizona, Utah, Colorado, and New Mexico, the First Americans became cliff dwellers(悬崖居民). They began by living in caves that already existed in the cliffs.__ 4.__ The dwellings(住处) they constructed in many ways resembled today's apartment buildings.__ 5.__ They built a system of dams and canals so they could store and use water almost any time of the year. They were so successful that they could raise fruits and vegetables that were not found naturally in the desert. In Mexico and South America, the First Americans founded civilizations that were among the greatest in the world. They built huge pyramids, lived in fabulous cities, and made great advances in science and mathematics long before the Europeans arrived.
A. They also discovered foods like corn and potatoes.
B. Along the way，they established（建立） many different civilizations.
C. The First Americans of the Southwest learned to irrigate（灌溉） the desert.
D. They would have to survive in the New World they had discovered.
E. They built boats of animal skins and hunted or fished for their food.
F. People living near each other tended to share similar environments and customs.
G. They discovered how to add to the caves by building structures of wood and stone.
I have a good memory of my grandfather，Jack. He was sitting in his armchair in the front room.
I sat next to him. We were reading aloud，our heads bent over the page in front of us，a finger marking the words；separated by seven decades，brought together by words. It's a common scene in British families；however，in our case，the usual order of things is reversed（颠倒）．Granddad had been blind since I was tiny，so I was reading to him.When reading aloud，people usually read something that's of interest to the listener. So I didn't read children's books；I read the sorts of things Granddad liked to hear about. Much of the vocabulary in Granddad’s reading material was far beyond me. When I met unfamiliar words，I'd spell them out.
Granddad would help me. It must have been painful for him to hear news；but he never hurried me along or complained. Our reading wasn't really about getting knowledge. It was a way for us to spend time together.
My grandfather wasn't always blind. He had been a good carpenter（木匠）．The first Christmas of my parents' marriage，he built my mother a bookcase，which now belongs to my son Jonah，providing a link between four generations.
I was a fortunate child；I spent a lot of time with my grandfather，and he opened the world to me in a particular way. Reading was our way of building a relationship that has had a lasting effect on me. In the school holidays，I sometimes accompanied him on trips to the seaside with the local association for the blind. This might seem strange，but I felt that my personal value was realized because I could finally do something for Granddad.
A decade later，I found a position in a nursing home，which reminded me of my early experiences；reading to senior citizens was a connection back to Granddad. More than simple conversation，reading aloud is a connection between two individuals and it can have a big emotional（情感的）effect on elderly people.

Motherhood may make women smarter and may help prevent dementia(痴呆) in old age by bathing the brain in protective hormones(荷尔蒙) , U.S. researchers reported on Thursday.
Tests on rats show that those who raise two or more litters of pups do considerably better in tests of memory and skills than rats who have no babies, and their brains show changes that suggest they may beprotected against diseases such as Alzheimer’s(早老痴呆症). University of Richmond psychology professor Craig Kinsley believes his findings will translate into humans.
“Our research shows that the hormones of pregnancy(怀孕) are protecting the brain, including estrogen(雌激素),which we know has many neuroprotective (保护神经的) effects,” Kinsley said. “It’s rat data but humans are mammals just like these animals are mammals,” he added in a telephone interview. “They go through pregnancy and hormonal changes.”Kinsley said he hoped public health officials and researchers will look to see if having had children protects a woman from Alzheimer’s and other forms of age-related brain decline.
“When people think about pregnancy, they think about what happens to babies and the mother from the neck down,”said Kinsley, who presented his findings to the annual meeting of the Society of Neuroscience in Orlando, Florida.“They do not realize that hormones are washing on the brain. If you look at female animals who have never gone through pregnancy, they act differently toward young. But if she goes through pregnancy, she will sacrifice her life for her infant—that is a great change in her behavior that showed in genetic alterations(改变) to the brain.”
