A mysterious machine found in a 2,000-year-old Greek shipwreck may have been used to calculate the positions of planets, predict when eclipses (日、月蚀) were to occur, and study other parts of astronomy (天文学). When it was found underwater about 100 years ago, the machine was in poor shape. Its metal pieces had become one mass (堆), and then broke into pieces.
When the researchers began to study what was left of the machine, they thought it might have something to do with astronomy. To find out more, they recently used advanced imaging methods, including X-ray computer tomography (断层摄影术), to look inside the metal parts and to check for ancient writing on the machine.
According to their research, the researchers believed that this machine could have been used to compute eclipses of the sun and moon and was also able to show the movements of planets. A user could pick a day in the future and, work out a planet’s position on that date by moving some sort of crank (曲柄) on the machine.
Besides, the researchers discovered that the machine had at least 30 bronze gears (齿轮) with as many as 225 teeth, likely all cut by hand.
With all the collected information, the researchers came up with a new model for how the machine operated. The model has 29 of the 30 known gears and five more that were probably there but never found. Also，the new picture adds a previously undiscovered spiral dial (螺旋刻度盘) to the back of the machine near the bottom. A hand moving around the dial could have pointed to eclipses over a period of 18 years.

A characteristic of American culture that has become almost a tradition is to respect the self-made man — the man who has risen to the top through his own efforts, usually beginning by working with his hands. While the leader in business or industry or the college professor occupies a higher social position and commands greater respect in the community than the common laborer or even the skilled factory worker, he may take pains to point out that his father started life in America as a farmer or laborer of some sort.
This attitude toward manual(体力的) labor is now still seen in many aspects of American life. One is invited to dinner at a home that is not only comfortably but even luxuriously (豪华地) furnished and in which there is every evidence of the fact that the family has been able to afford foreign travel, expensive hobbies, and college education for the children; yet the hostess probably will cook the dinner herself, will serve it herself and will wash dishes afterward, furthermore the dinner will not consist merely of something quickly and easily assembled from contents of various cans and a cake or a pie bought at the nearby bakery. On the contrary, the hostess usually takes pride in careful preparation of special dishes. A professional man may talk about washing the car, digging in his flowerbeds, painting the house. His wife may even help with these things, just as he often helps her with the dishwashing. The son who is away at college may wait on table and wash dishes for his living, or during the summer he may work with a construction gang on a highway in order to pay for his education.From paragraph 1, we can know that in America _________.
| A．people feel painful to mention their fathers as laborers |
| B．people can always rise to the top through their won efforts |
| C．college professors win great respect from common workers |
| D．people tend to have a high opinion of the self-made man |
According to the passage, the hostess cooks dinner herself mainly because _________.
| A．servants in American are hard to get |
| B．she takes pride in what she can do herself |
| C．she can hardly afford servants |
| D．It is easy to prepare a meal with canned food |
The expression “wait on table” in the second paragraph means “_________”.
| A．wait to lay the table |
| B．keep accounts for a bar |
| C．serve customers in a restaurant |
| D．work in a furniture shop |
Which of the following may serve as the best title of the passage?

| B．A Respectable Self-made Family |
| C．Characteristics of American Culture |
| D．The Development of Manual Labor |
For a long time the packaging industry has been attacked for using what is thought as large amounts of packaging, choosing materials which are felt to have high impacts on the environment, and for being responsible for littering and overflowing land fills. In a study performed by WRAP, one of the first to study food waste in the UK in 2012, the most frequent responses when consumers were asked about packaging were “uses too much material” and “bad for the environment”. The conclusions of these reports highlighted that the degree of the problem has been largely underestimated：at least 30% of food produced in the world is wasted. These figures are similar no matter if you are in the developed or developing world.
However, two publications from cross—industry work groups were published recently, and have managed to reset the discussion to take into account the benefits of packaging for sustainability(可持续性).The first publication, “The Global Protocol on Packaging Sustainability”, describes an agreed common approach towards measuring packaging sustainability metrics(指标), so that the industry is not competing based on the definition of a metric, but rather competing based on performance. The second was, “'Packaging in the Sustainability Agenda, A Guide for Corporate Decision Makers”, which highlighted the contributions of packaging to the three aspects of sustainability: packaging protects products and prevents waste(environmental aspect); packaging enables efficient business conduct(economic aspect); and packaging provides consumers with the benefits of the products it contains(social aspect).
Packaging performs indeed a wide variety of functions throughout the value chain and contributes to reducing food waste by protecting ingredients(佐料)and products during transportation and by delivering family—sized packages. Food waste could be avoided for single households if they are provided with the choice of pack sizes meeting their consumption patterns and are not forced to buy larger packs that they may not be able to finish before the use—by date. Despite the fact that smaller sized packs use more packaging, the fact that food waste is reduced would nevertheless decrease overall environmental impacts of the packed product.It has long been thought that _______.
| A．larger quantities of food are wasted in developed countries |
| B．WRAP is the first authority to study food waste in UK |
| C．packaging does great harm to the environment |
| D．packaging offers a powerful means to reduce food waste |
According to the two publications in Paragraph 2，_______.
| A．an agreement should be reached on measuring packaging sustainability |
| B．the industry should compete based on the definition of sustainability metrics |
| C．smaller sized packs promotes less packaging and purchase among consumers |
| D．sustainable packaging is eco-friendly，economically practical and socially beneficial |
The author’s attitude towards packaging is ___________.
| A．approving | B．negative |
| C．casual | D．doubtful |

My brother-in-law opened the bottom drawer of my sister's bureau(衣橱) and picked out a wonderful skirt. "Jan bought this the first time we went to New York, at least 8 or 9 years ago. She never wore it. She was saving it for a special occasion.” Well, I guess this is the occasion.
He took the skirt from me and put it on the bed. His hands touched the soft material for a moment, then he shut the drawer and turned to me, "Don't ever save anything for a special occasion. Every day you're alive is a special occasion."
I'm still thinking about his words, and they've changed my attitude to life. I'm spending more time with my family and friends and less time in committee meetings. Whenever possible, life should be a pattern of experience to enjoy, not suffer. I'm trying to recognize these moments now and treasure them.
"Someday" and "one of these days" are being lost from my vocabulary. If it's worth seeing or hearing or doing, I want to see and hear and do it now. I' m not sure what my sister would have done if she had known she wouldn't have tomorrow.
I think she would have called family members and a few close friends. She might have called a few former friends to apologize and mend her fences for past things. I like to think she would have gone out for a Chinese dinner, her favorite food.
If I knew that my hours were limited, those little things left undone would make me angry. Angry because I put off seeing good friends whom I was going to get in touch with some day. Angry and sorry because I didn't tell my husband and daughter often enough how much I truly love them.
I'm trying very hard not to put off, hold back, or save anything that would add laughter to our lives. And every morning when I open my eyes, I tell myself that every day, every minute; every breath truly, is... a gift from God.The best title for the passage would be______.
| A．Every day is An Important Occasion | B．My Poor Sister |

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 be protected 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.”How do scientists know “Motherhood may make women smarter”?
| A．Some researchers have told them. |
| B．Many women say so. |
| C．They know it by experimenting on rats. |
| D．They know it through their own experience. |
What does the phrase “litters of pups” mean in the second paragraph?
| A．Baby rats. | B．Animals. |
| C．Old rats. | D．Grown-up rats. |
What can protect the brain of a woman according to the passage?
| A．Estrogen. | B．The hormones of pregnancy. |
| C．More exercise. | D．Taking care of children. |
Which title is the best for this passage?
| A．Do You Want to Be Smarter? |
| B．Motherhood Makes Women Smarter |
| C．Mysterious Hormones |
| D．An Important Study |
