Have you thanked your grandma today? You might want to consider it. A recent study found that kids live longer when a grandmother takes part in their daily lives. Most animals die soon after their childbearing years are over. Women, however, often live for many years after they stop having kids. To try to understand why, researchers from Finland looked at birth and death records of two communities from the 18th and 19th centuries, one in Finland and one in Canada. In these communities, 537 Finnish women and 3,290 Canadian women were grandmothers who had lived past the age of 50. For every decade they lived beyond 50, the researchers found that the women ended up with an average of two extra grandkids. It didn't matter what the differences in health or living conditions were between the two communities or from family to family. Grandchildren were also more likely to live into adulthood if their grandmothers were alive when they were born. If their grandmothers were younger than 60 at the time, that was even better. The study also found that women had children 2 to 3 years earlier if their own mothers were still alive at that time than those whose mothers had died. The researchers suggested that grandmothers have provided important assistance in raising their grandchildren for at least the past 200,000 years. As a result, they helped extend everyone's lifespan. So, don't take your grandma for granted! According to the passage, we don't know that _ . A) kids live longer when grandmothers take part in their daily lives B) most animals die soon after their childbearing years are over C) women often live for many years after they stop having kids D) grandchildren are less likely to live into adulthood if their grandmothers are alive

Without plant, people could not live. We eat plants. We breathe the oxygen that plants produce. And we need plants for another reason: we need them for their beauty. Imagine a world with no plants. Imagine no flowers with their sweet smells, their beautiful colors and their lovely shapes. Imagine when the wind blows, not being able to hear the leaves in the trees or watch the branches sway from side to side. Everywhere people need the beauty of plants. That is why we have parks full of trees and flowers. That is why people always try to design houses with room for some grass and a garden. Do you talk to your plants? Do you give them love and attention? Peter Tompkins and Christopher Bird, writers of a book called THE SECRET LIFE OF PLANTS, tell of an experiment in which two seeds were planted in different places. While the plants were growing, one plant was given love and hopeful ideas. The other plant was given only hopeless ideas. After six months, the loved plant was bigger. Under the earth it had more and longer roots; above the earth, it had a thicker stem and more leaves. The experiment has proved that _ -. A) we should talk to plants and give them love B) without plants people could not live C) we should grow as many plants as possible D) plants need plenty of water, sunshine and attention

Q: The Ivy League is an athletic conference comprising eight private institutions of higher education in the Northeastern United States. The term is most commonly used to refer to those eight schools considered as a group. The term is also connected with academic excellence, selectivity in admissions, and social elitism . The term became official, especially in sports terminology, after the formation of the NCAA Division I athletic conference in 1954, when much of the nation polarized around favorite college teams. "IV" was used because originally the league consisted only of four members. The use of the phrase is no longer limited to athletics, and now represents an educational philosophy inherent to ( ,)the nation's oldest schools. In addition, Ivy League schools are often viewed by the public as some of the most prestigious universities worldwide and are often ranked amongst the best universities in the United States and worldwide. The eight institutions are Brown University, Columbia University, Cornell University, Dartmouth College, Harvard University, Princeton University, the University of Pennsylvania, and Yale University. All of the Ivy League's institutions place near the top in theU.S. News & World Reportcollege and university rankings and rank within the top one percent of the world's academic institutions in terms of financial endowment . Seven of the eight schools were founded during America's colonial period; the exception is Cornell, which was founded in 1865. Ivy League institutions, therefore, account for seven of the nine Colonial Colleges chartered before the American Revolution. The Ivies are all in the Northeast geographic region of the United States. All eight schools receive millions of dollars in research grants and other subsidies from federal and state government. Undergraduate enrollments among the Ivy League schools range from about 4,000 to 14,000, making them larger than those of a typical private liberal arts college and smaller than a typical public state university.
