A
Older adults who sleep six hours or fewer a night may have elevated risk for dementia(痴呆症) and other cognitive (认知的) issues, a new study finds.
Researchers at Stanford University measured seniors' (ages 65 to 85) dementia risk and cognitive abilities, finding higher risk in those patients who regularly slept six or fewer hours compared to those who slept seven or eight hours. Those seniors who slept nine or more hours also had lower cognitive functions and other health issues, but the researchers didn't find the same high dementia risk in this group.
The findings demonstrate how important it is for adults to maintain a healthy sleep cycle, especially as they get older.
As adults age, it's common for their sleep patterns to change or becomedisrupted— leading to longer, shorter, or more irregular sleep. This disruption may be linked to Alzheimer's and other forms of dementia, impacting seniors' ability to remember information, problem-solve, and go through everyday behaviors. Sleep disruption can also be caused by or heighten depression, cardiovascular disease（冠心病）, and other conditions.
A recommended sleep time for seniors is seven to eight hours, the researchers said. Six or fewer hours corresponded to short sleep, while nine or more hours corresponded to long sleep.
The Stanford researchers measured levels of beta amyloid, a protein in the brain that is typically found in high levels when a patient develops Alzheimer's. In addition, the researchers used several tests for memory, attention, spatial skills, and executive function to identify patients' cognitive abilities. Those patients sleeping for six hours or fewer a night were more likely to develop dementia, the researchers found. The low-sleep patients had higher levels of beta amyloid.
The Stanford researchers found that patients with lower sleep also performed worse on memory tests, while those with higher sleep (more hours) performed worse on executive function tests，which measure the brain's ability to switch between different tasks.
―The main takeaway is that it is important to maintain healthy sleep late in life, Winer told CNN.
1. What does the underlined word “disrupted” in paragraph 4 mean?
A. difficult

D. different
2. According to the findings, which of the following is NOT related to the disrupted sleep?
A. It is more likely to cause old people to have bad memories over issues.
B. It may contribute to dementia, cardiovascular disease and other illnesses.
C. Some daily behaviors perhaps differ from those whose sleeping is normal.
D It tends to bring all the old people to undergo brain scans and cognitive tests.
3. What can we infer from the study?
A. A proper sleep time for seniors is seven to eight hours.
B. Low and high sleep patients were both poor at memory tests.
C. Executive function test is applied to measure the capacity of brain.
D. Keeping a healthy sleep for older adults late in life is crucial.
B
Paper is one of our oldest, simplest and most important inventions. But it also presents a danger to the world in two important ways. First, the making of paper requires the loss of many millions of trees each year. And worldwide use of paper is expected to double in the next 40 years. Clearly, the planet cannot stand such a high rate of forest loss. The second great problem with paper is what happens once it is no longer useful. A large amount of wastepaper ends up in landfills, where it can produce harmful gases and finally contribute to global climate change.
One simple solution can greatly reduce both of these problems: paper recycling. Instead of cutting down trees, recycle existing paper to feed the paper-making process.
Paper is mainly made from cellulose (纤维素)，which can be used repeatedly in papermaking. Unfortunately, it also means that paper waste takes a surprisingly long time to break down in landfills. So far, trees are the only source(来源) of cellulose that can fill the great demand for paper products. Therefore, recycling paper is simply one of the best ways to save trees. Thanks to advances in processing, recycled paper need not be the dark-color1 edstuff many of us are familiar with. It now can offer the same print performance as non-recycled paper.
Effective recycling requires a continuous effort from everyone at all levels of society. The way to begin is with education and understanding. Once enough people realize the need for recycling, more effective recycling systems can be developed.
The need is real. The massive loss of trees affects everybody on earth. Everyone should do their part to recycle paper and encourage government and industry to do the same. The world will be a better place for it!
4. What can we infer from the text?
A. The use of recycled paper will double in 40 years.
B. Recycling paper helps relieve global climate change.
C. Wastepaper can easily break down in landfills.
D. There are not enough landfills for wastepaper.
5. What makes recycled paper more acceptable?
A. The great demand of trees.
B. The low processing cost.
C. Its dark-color1 ed feature.
D. Its improved print performance.
6. What does the author propose?
A. Punishing the act of cutting trees.
B. Recycling paper.
C. Improving recycling system.
D. Promoting paper industry.
7. How is the text mainly developed?
A. By analyzing causes and effects.
B. By offering research plans and data.
C. By discussing problems and solutions.
D. By comparing strengths and weaknesses.
C
The grocerystore might not be your favorite place to visit when you're at home, but is it ever fun when you're in another country? Honestly speaking, they're one of those strange little destinations that I like to sniff out everywhere I go, much as other travelers head toward clothing stores, libraries, coffee shops or galleries.
The greatest beauty of the grocery store –– whether it's a supermarket or a tiny shop –– is that it gives you a glimpse into what local people buy to cook their own meals. This offers clues into their lifestyles and preferences, and into the agricultural and cooking practices of the country. I stare at the strange fruits and vegetables, the seafood, the cheese, the spices, the bread, and oh, the chocolate...always the chocolate!
Being the environmental nerd（呆子）I am, I like paying attention to packaging, which can reflect people's attitudes towards environmental protection. Italy, for example, has a habit of requiring customers to bag their fruits and vegetables in plastic for weighing, while Sri Lanka leaveseverything loose in bins. In Brazil, everything is prepackaged in a layer of plastic.
People in grocery stores tend to be friendlier. They smile, say hello, and sometimes ask questions, which can lead to great conversations. I had a further discussion with a teenaged cashier in Sri Lanka, over which bag of crunchy（松脆的）mix to buy. He insisted that the one labeled “spicy” would be too hot for me, but I told him I was willing to risk it. He laughed and we ended up talking about my favorite Sri Lankan foods for ten minutes.
It's interesting then to come home and look at one's own local grocery store through new eyes. What would a visitor think? What stands out, and what do the food displays say about us as a culture? You might be surprised by what you realize.
8. According to the author, what is the key benefit of visiting foreign grocery stores?
A. Learning to cook foreign dishes.
B. Making friends with local people.
C. Buying cheaper food and souvenirs.
D. Knowing local people and the country.
9. What does the author show by mentioning some countries in paragraph 3?
A. People's special lifestyles.
B. People's shopping habits.
C. People's environmental awareness.
D. People's packaging methods.
10. What can we infer from paragraph 4?
A. Sri Lankans know a lot about food.
B. Grocery stores are good social places.
C. Grocery stores vary in different countries.
D. Sri Lankans like to give strangers suggestions.
11. Which of the following shows the structure of text? (P: paragraph)
A. B.
C. D.
D
The Gata used to look annoyed when they received power bills that routinely topped $200. Last September
the couple moved into a 1,500-square-foot home in Premier Gardens, an area of 95 “zero-energy homes” (ZEH) just outside town. Now they're actually eager to see their electricity bills. The grand total over the 10 months they've lived in the three-bedroom house: $75. For the past two months, they haven’t paid a cent.
ZEH communities are the leading edge of technologies that might someday create houses that produce as much energy as they consume. Premier Gardens is one of a half-dozen subdivisions (住宅开发项目) in California where every home cuts power consumption by 50%, mostly by using low power appliances and solar panels.
Aside from the panels on the roof, Premier Gardens looks like a community of traditional homes. But inside, special windows cut power bills by blocking solar heat in summer and keeping indoor warmth winter.
The rest of the energy savings comes from the solar units. They don't just feed the home they serve. If they generate more power than the home is using, the excess flows into the utility's power grid(电网). The residents are billed by “net metering”: they pay for the amount of power that they get from the grid, minus the kilowatts(千瓦) they feed into it. If a home generates more power than it uses, the bill is zero.
That sounds like a bad deal for the power company, but it's not. Solar homes produce the most power on the hot sunny afternoons when everyone rushes home to turn up the air conditioner. "It helps us lower usage at peak power times," says solar expert Mike Keesee. “That lets us avoid building costly plants or buying expensive power at peak usage time.”
What’s not to like? Mostly the costs. The special features can add $25,000 or more to the purchase price of a house. Tax breaks bring the cost down, especially in California, but in many states ZEHs can be extremely expensive. For the consumer, it's a matter of paying now for the hardware to save later on the power bill.
12. Why is the Gata eager to see their electricity bills now?
A. They want to cut down their utility' expenses.
B. They want to know if they are able to pay.
C. They want to see how much they have saved.
D. They want to avoid being overcharged.
13. What is special about the ZEH communities?
A. They are built in harmony with the environment.
B. They have created cutting edge technologies.
C. They are subdivided into half a dozen sections.
D. They aim to be independent in power supply.
14. What does the "net metering" practice mean to the power company?
A. More pressure at peak time
B. Reduced operational costs.
C. Increased electricity output.
D. Less profits in the short term.
15. The author believes that buying a house in a ZEH community __________.
A. is a worthy investment in the long run
B. is but a dream for average consumers
C. gives the owner great tax benefits
D. contributes toenvironmental protection

He might not realize he's being rude. If hecares, he'll apologize and try to be more polite.____19____If he's a coworker or next-door neighbor, it's difficult to completely stay away from him, but you can limit your contact as much as possible.
●Offer extra kindness.
____20____However, if you are able to keep your head up and set an example, sometimes the other person will eventually calm down and follow your lead. Don't count on this happening, but it might be worth a shot if you don't have a choice but to be around him.
A. Nothing is impossible to tolerate.
B. Call the person out on his behavior.
C. If he doesn't, then you need to avoid this person.
D. Here are some ways you can try to deal with them.
