Yours，
Li Hua
Do you have the experience of digging out your suitcase, deciding what to bring and being afraid that you’ve forgotten something?1.. Hope they can transform the way you pack.
Keep a Basket Handy
Do you wait until the last minute to pack? Keep a basket in your bedroom, living room, or bath room that you can use to throw in items you’ll need to pack as you come across them. 2.. Besides, you can just put the contents of the basket into your suitcase if you are in a hurry to leave for the airport.
Buy Wrinkle-free Clothing
You won’t need to worry about carefully packing your items of clothing if they’re made from wrinkle-free materials. 3.. You’ll still look fresh and bright when you are in them at your destination.
Keep Old Packing Lists
Chances are that you end up taking trips that require you to pack similar items. Keep old packing lists from former vacations to the beach, ski resort, and city—that way, you’ll always have a list of at least the basics. 4.. So you don’t need to waste your effort to remember where you left your hand-written packing lists.
Schedule a Packing Time
Time can slip away from you before a trip-you may be caught up at work, at home, or be occupied with other responsibilities of daily life.5.. That way, you will not need to do your packing frantically (狂乱地) from the last minute to 1 o’clock on the day you leave.
A. Buy necessary stuff when you arrive.
B. That’s why I’ve distilled (提炼) the art of packing down to some essential tips.
C. This makes you less likely to forget the stuff.
D. Rolling your clothes is the best way to save space for the suitcase.
E. The best way to do this is to save them on your computer.
F. Just ball them up or put them at the bottom of the suitcase.
G. Determine a night well in advance of departure to pack.
Why do some people live to be older than others? You know the standard explanations: keeping a moderate diet, engaging in regular exercise, etc. But what effect does your personality have on your longevity（长寿）? Do some kinds of personalities lead to longer lives? A new study in the Journal of the American Geriatrics Society looked at this question by examining the personality characteristics of 246 children of people who had lived to be at least 100.
The study shows that those living the longest are more outgoing, more active and less neurotic (神经质的) than other people. Long-living women are also more likely to be sympathetic and cooperative than women with a normal life span. These findings are in agreement with what you would expect from the evolutionary theory: those who like to make friends and help others can gather enough resources to make it through tough times. Interestingly, however, other characteristics that you might consider advantageous had no impact on whether study participants were likely to live longer. Those who were more self-disciplined, for instance, were no more likely to live to be very old. Also, being open to new ideas had no relationship to long life, which might explain all those bad-tempered old people who are fixed in their ways.
Whether you can successfully change your personality as an adult is the subject of a longstanding psychological debate. But the new paper suggests that if you want long life, you should strive to be as outgoing as possible.
Unfortunately, another recent study shows that your mother’s personality may also help determine your longevity. That study looked at nearly 28,000 Norwegian mothers and found that those moms who were more anxious, depressed and angry were more likely to feed their kids unhealthy diets. Patterns of childhood eating can be hard to break when we’re adults, which may mean that kids of depressed moms end up dying younger. Personality isn’t destiny, and everyone knows that individuals can learn to change. But both studies show that long life isn’t just a matter of your physical health but of your mental health.
1.The aim of the study in the Journal of the American Geriatrics Society is____.
A. to investigate the role of exercise in living a long life
B. to find out if one’s lifestyle has any effect on their health
C. to see whether people’s personality affects their life span
D. to examine all the factors contributing to longevity
2.What does the author imply about outgoing and sympathetic people?
A. They are more likely to get over hardship.
B. They are better at negotiating an agreement.
C. They generally appear more resourceful.
D. They have a good understanding of evolution.
3.What finding of the study might prove somewhat out of our expectation？
A. Personality characteristics that prove advantageous actually vary with times.
B. Easy-going people can also live a relatively long life.
C. Readiness to accept new ideas helps one enjoy longevity.
D. Such personality characteristics as self-discipline have no effect on longevity.
4.What can we learn from the findings of the two new studies?
A. Anxiety and depression more often than not cut short one’s life span.
B. Health is in large part related to one’s lifestyle.
C. Personality plays a decisive role in how healthy one is.
D. Longevity results from a combination of mental and physical health.
Since English biologist Charles Darwin published On the Origin of Species in 1859, scientists have vastly improved their knowledge of natural history. However, a lot of information is still of the speculation, and scientists can still only make educated guesses at certain things.
One subject that they guess about is why some 400 million years ago, animals in the sea developed limbs (肢) that allowed them to move onto and live on land.
Recently, an idea that occurred to the US paleontologist (古生物学家) Alfred Romer a century ago became a hot topic once again.
Romer thought that tidal (潮汐的) pools might have led to fish gaining limbs. Sea animals would have been forced into these pools by strong tides. Then, they would have been made either to adapt to their new environment close to land or die. The fittest among them grew to accomplish the transition (过渡) from sea to land.
Romer called these earliest four-footed animals “tetrapods”. Science has always thought that this was a credible theory, but only recently has there been strong enough evidence to support it.
Hannah Byrne is an oceanographer (海洋学家) at Uppsala University in Sweden. She announced at the 2018 Ocean Sciences Meeting in Oregon, US, that by using computer software, her team had managed to link Homer’s theory to places where fossil deposits (沉积物) of the earliest tetrapods were found.
According to the magazine Science, in 2014, Steven Balbus, a scientist at the University of Oxford in the UK, calculated that 400 million years ago, when the move from land to sea was achieved, tides were stronger than they are today. This is because the planet was 10 percent closer to the moon than it is now.
The creatures stranded in the pools would have been under the pressure of “survival of the fittest”, explained Mattias Green, an ocean scientist at the UK’s University of Bangor. As he told Science, “After a few days in these pools, you become food or you run out of food... the fish that had large limbs had an advantage because they could flip (翻转) themselves back in the water.”
As is often the case, however, there are others who find the theory less convincing. Cambridge University’s paleontologist Jennifer Clark, speaking to Nature magazine, seemed unconvinced. “It’s only one of many ideas for the origin of land-based tetrapods, any or all of which may have been a part of the answer,” she said.
1.Who first proposed the theory that fish might have gained limbs because of tidal pools?
A. Hannah Byrne. B. Charles Darwin.
C. Alfred Romer. D. Steven Balbus.
2.Why were tides stronger 400 million years ago than they are today according to Steven Balbus?
A. There were larger oceans. B. Earth was under greater pressure.
C. The moon gave off more energy. D. Earth was closer to the moon.
3.The underlined word “stranded” in Paragraph 8 probably means “________”.
A. trapped B. settled
C. abandoned D. found
4.What is the focus of the article?
A. The arguments over a scientific theory.
B. Some new evidence to support a previous theory.
C. The proposal of a new scientific theory.
D. A new discovery that questions a previous theory.
