As time went on, hot sun and cool rains made the rock split and break to pieces. Sea waves dashed against the rock. In this way, soil and sand came into being.
Nothing lived on the naked soil. And then the wind and birds brought plant seeds, spiders and other little creatures there. Only plants could grow first. Only they, in sunlight, could produce food from the minerals of the soil, water and air. While many animals landed on the island, they could find no food. A spider spun its web in vain, because there were no insects for its web to catch, In sects couldn' t stay until there were plants for them to eat. So plants had to be the pioneer life on this new island.
The passage centers on ______.
A．how an undersea volcano broke out
B．how an island rose up in the sea
C．how soil was formed on a new island
D．how life began on a volcano-produced island

The study adds to a growing body of evidence that there' “an intimate relationship between the amount of sleep we get and our ability to maintain a good, healthy body weight,” says sleep expert Helene Emsellem, director of the Center for Sleep and Wake Disorders in Chevy Chase, Maryland. But Americans don't seem to be getting the message that we need seven to nine hours par night. More than 1 in 5 of us, according to a report from the Centers for Disease Control and Prevention, is getting six or fewer hours of sleep per night, on average.
So how did researchers study fat cells in the Annals paper？ Matthew Brady of the University of Chicago and a group of colleagues selected and persuaded seven volunteers to take part in the research project. They were all young, thin and healthy and agreed to sleep for eight nights in a sleep lab. “For four nights they were allowed to stay in bed for 8.5 hours a night,” says Brady. Then, a month later, they came back for four additional nights——but this time they were allowed just 4.5 hours of sleep per night. And after each visit, researchers got a sample of their fat. Brady explains that the fat cells responded significantly to the loss of sleep. “I was very surprised to be honest,” he says.
Bad things can happen when fat cells become less responsive to insulin. “Fat cells are actually your friend,” he says. “They're there to store lipids (血脂).” When lipids stay inside the cells, your body can utilize the fat when you're exercising or sleeping or going about your day. “However, when fat cells stare to become insulin resistant, the lipids star to leach out of the fat cells and rise in the bloodstream,” Brady says.
1. According to the passage, lack of sleep for a long while can probably lead to all of the following EXCEPT {A; B; C}.
A. heart disease
B. weight gain
C. diabetes
2. The main idea of the third paragraph is {A; B; C}.
A. how to write a medical research paper
B. how to avoid sleep loss
C. how the research was conducted
3. What does the “leach” in the last paragraph probably mean？{A; B; C}
A. Leap.
B. Lead.
C. Leak.
4. Which of the following is NOT TRUE according to the passage？{A; B; C}
A. We will be in trouble if our fat cells become less responsive to insulin.
B. More and more studies are done to study the link between sleep and weight.
C. More than 20% of Americans are not getting enough sleep.
5. Which of the following is an appropriate title for this passage？{A; B; C}
A. Poor Sleep May Lead to Too Much Stored Fat and Disease
B. Sleep Experts Had Exciting Findings in a Fat Study
C. Americans Should Have More Than Six Hours of Sleep
Section B
Directions: There are 2 passages in this section. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A, B, C and D. You should decide on the best choice.
I often hear people say that the lack of women in positions of political leadership is an issue that pales next to world crises-global terrorism, fragile economies, inadequate health care and troubled schools. They see no connection between the frightening situations we're in and the fact that few women sit at the table to determine the solutions.
This fundamental imbalance, with men running the world and women mostly spectators, is not a trivial detail. It is the problem. It is also the one solution we have not tried on and the one most likely to work.
This is not just me talking. Three decades of research in state legislatures, universities, and international public policy centers have proven beyond doubt that women, children, and men all benefit when women are in leadership. Broader social legislation, benefiting everyone, is more likely to pass if women are in office. We know the power of women as peacemakers in the world from scores of stories about their effectiveness at negotiation, from Ireland to Norway to South Africa and beyond.
We can ill afford to use only half our talent, when we know for a fact that today's complicated challenges demand more than one vision. It's time for real and permanent power sharing, for real and permanent change women ruling side by side with men, allowing their voices to rise with different solutions and allowing men to think outside of the masculine box. In this way, we get fresh eyes and fresh solutions from both genders, applied to both old, durable problems and to new, frightening ones.
This is not a call to move power from the fingers of men and turn it all over to women. Together we can create a different world, shifting the burden from male shoulders and allowing the variety of thought and life experience to transform. our actions—perhaps bringing a greater peace, perhaps allowing men to be better fathers, perhaps providing a new pattern for our security.
It's not easy to get there. Those in power rarely let go without a fight, even if they would benefit by doing so. For women to truly gain the leadership roles, we must be insistent and persistent. We must enlist our many male allies. We must let it be known that we are ready to lead, that in fact we demand it as a birthright. If we think creatively, if we use our community resources, if we support women who say they want to lead, if we use our voices and our votes to get there, we will achieve the transformation of power.
What is said about the actuality of the political leadership structure？
A．Men run the world, while the women watch them.
B．Men operate our world, while women help them.
C．There are almost half women political leaders now.
D．Lack of women political leaders is the biggest problem.
Which of the following is the best definition of a civilization？
A．Neolithic towns and cities
B．Types of complex cultures
C．An agricultural community
D．Large population centers

All but the tiniest of roads have to have names so they can be recognized on a map, and so people can ask directions to them. Americans name a lot of bridges, too.
Very often these names carry a clear geographical reference the Pennsylvania Turnpike, for example. Or,like the George Washington Bridge, roads and bridges are named for famous historical figures or powerful officers. We make a big deal out of naming things, as when someone decided to name an airport after a U. S. judge.
So now we have the Baltimore Washington International Thurgood Marshall Airport. Many,if not most, of our college buildings are named for wealthy people who gave a lot of money to the schools. And our sports centers took this idea a step further. Companies paid a whole lot of money for what′s called the "naming rights" to U. S. Cellular Field in Chicago, for example, and Citizens Bank Park in Philadelphia.
Now the governor(州长) of Virginia, Bob McDonnell,wants to sell naming rights to roads and bridges in the state. He says not just companies, but also wealthy people, would help the Virginia transportation budget(预算) by paying to have their names--or perhaps those of loved ones--placed on roads and bridges, and thus on maps as well. People hold different views, however. Supporters say Americans are used to having things sponsored(赞助). Others disagree, considering the idea as the next step in the "companies of America. " They wonder how far such an idea might spread, and where it would end:at the Burger King Pacific Ocean, perhaps.
Most of the roads need to have names so that____.
A.they can remind people of the past
B.people can learn about them better
C.they can be easily recognized on mapss
D.people can enjoy naming them
Who are many college buildings named for according to the passage？A.Powerful officers.
B.Famous judges.
C.Historical figures.
D.Wealthy peopl
What can we learn from the last paragraph？A.People have different ideas toward naming things.
B.Americans have sponsored naming a lot.
C.Everything is named by an American company.
D.Pacific Ocean will be rename
Why does the governor of Virginia want to sell naming rights？A.To remember the loved names.
B.To make the state well-known.
C.To help the transportation budget.
D.To increase companies' sales.

To whom it may concern,
As my watch (model: 5M43-0B19, S/N: 6D8256) was clearly in need of repair, I recently took it to the Lexington Repair Center where the defective components in the watches are repaired. To my surprise, my request for the repairs to be billed to your company was declined in spite of the fact that there are still three years remaining in the coverage period. As there are no other authorized service centers in my area, I decided to pay for the repairs myself.
The following are the charges billed by the service center:
Parts:
New mainspring...........$23
New hour hand.............$8
New battery...................$5
Labor.............................$34
Total..............................$70
Showing prices including tax
I have included a copy of the receipt I got for the repairs and a copy of my warranty certificate. Please let me know if you need any additional information.
Regards,
Tomas Rodriguez
