Mars( 火星) appears to be flowing with small streams of salty water, at least in the summer, scientists reported Monday. "It suggests that. it would be possible for there to be life today on Mars," NASA's science mission chief, John Grunsfeld, said at a news conference on September 28, 2015.

The streams are about 12 to 15 feet wide and 300 feet or more long, scientists said. "What we're dealing with is wet soil. thin layers of wet soil, not standing water," said Aifred McEwen of the University of Arizona at Tueson ! the principal scientist for the Mars Reconnaissance Orbiter's high-resolution imaging experiment.

Because liquid water is essential to life, the findings could have major implications for the possibility of Martian life. The researchers said further exploration is needed to determine whether microscopic life exists on the planet.

The presence of liquid water could also make life easier for astronauts visiting or living on Mars. Water could be used for drinking and for creating oxygen and rocket fuel. NASA's goal is to send humans there in the 2030s.

The evidence of flowing water consists largely of dark, narrow streaks(條痕) on the surface that tend to appear and grow during the warmest Martian months and fade the rest of the year.

Mars is extremely cold even in summer, and the streaks are in places where the temperature is as low as minus 10 degrees Fahrenheit. But salt can lower the freezing point of water and melt ice.

The source(源頭) of the water is a mystery. Scientists noted it could be melting ice. It could be an underground aquifer, which is rock or sand that can hold water. It is possibly water vapor from the thin Martian atmosphere, Or it may be a combination.

Michael Meyer, lead scientist for NASA's Mars exploration program, said the only definitive way for now to determine whether there's life on Mars is to collect rocks and soil for analysis on Earth - something a U. S. lander set for lift-off in 2020 will do.

Are people less happy or more happy the older they get ? A study found that people generally become happier and experience less worry after age 50. In fact, it found that by the age of 85, people are happier with their life than they were at 18.

The finding came from a Gallup survey of more than 340,000 adults in the United States in 2008. At that time, the people were between the age of 18 an 85.

Arthur Stone in the Department of Psychiatry and Behavioral Science at Stony Brook University in New York led the study. His team found that levels of stress were highest among adults between the ages of 22 and 25. Stress levels dropped sharply after people reached their fifties.

Happiness was highest among the youngest adults and those in their early seventies. But the people least likely to report feeling negative emotions(消極情緒) were those in their seventies and eighties. The survey also found that men and women had similar emotional patterns as they grow older. However, women at all ages reported more sadness, stress and worry than men did.

The researchers also considered possible influences like having young children, being unemployed or being single. But they found that influences like these did not affect the levels of happiness and well-being related to age.

So why would happiness increase with age ? One theory is that, as people get older, they become more thankful for what they have and have better control of their emotions. They also spend less time thinking about bad experiences.

The original(最初的) goal of the study was to confirm the popular belief that aging is connected with increased sleep problems. The survey did find an increase during middle age, especially in women. But except for that , people reported that they felt their sleep quality improved as they got older.

1.Old people may be happier probably because _________

A. their children have grown up.

B. they don’t have to work every day.

C. they can do whatever they like best.

D. they are most likely satisfied with life.

2.According to the survey, when will adults feel most stressful?

A. In their twenties. B. In their fifties.

C. In their seventies. D. In their eighties.

3.What may make Arthur Stone a bit surprised?

A. Women usually live longer than men.

B. Middle-age men mostly are very rich.

C. Old people usually have a better sleep.

D. Most of old people can’t sleep well at night.

4.Which of the following may be the topic of this passage ?

A. The difference between men and women.

B. Old people’s feeling of happiness.

C. The young people and the old people.

D. The connection of sleep and happiness.

"Ok," I said to my daughter as she bent over her afternoon bowl of rice. "What's going on with you and your friend J.?" J. is the leader of a group of third-graders at her camp—a position Lucy herself occupied the previous summer. Now she's the one on the outs, and every day at snack time, she tells me all about it, while I offer up the unhelpful advice all summer long.

"She's fond of giving orders," Lucy complained. "She's fat," Lucy mumbled（含糊地說）to the bowl "We are going upstairs," I said, my voice cold, "We are going to discuss this." And up we went.

I'd spent the nine years since her birth getting ready for this day, the day we'd have to have

the conversation about this horrible word. I knew exactly what to say to the girl on the receiving end of the teasing（嘲笑），but in all of my imaginings, it never once occurred to me that my daughter would be the one who used the F word一Fat.

My daughter sat on her bed, and I sat beside her. “How would you feel if someone made fun of you for something that wasn't your fault?” I began. “She could stop eating so much,” Lucy mumbled, mouthing the simple advice a thousand doctors and well-meaning friends and relatives have given overweight women for years．

"It's not always that easy,” I said. “Everyone's different in terms of how they treat food”

Lucy looked at me, waiting for me to go on. I opened my mouth, then closed it. Should I tell her

that, in teasing a woman's weight, she's joined the long, proud tradition of critics who go after any woman with whom they disagree by starting with "you're ugly" and ending with “no man would want you and there must be something wrong with any man who does"？Should I tell her I didn't cry when someone posted my picture and commented, “I'm sorry, but aren't authors who write books marketed to young women supposed to be pretty?”

Does she need to know, now, that life isn't fair? I feel her eyes on me，waiting for an answer I don't have. Words are my tools．Stories are my job．It's possible she'll remember what I say forever, and I have no idea what to say.

So I tell her the only thing I can come up with that is absolutely true．I say to my daughter,

“I love you, and there is nothing you could ever do to make me not love you. But I'm disappointed in you right now. There are plenty of reasons for not liking someone. What she looks like isn't one of them.”

Lucy nods, tears on her cheeks.“I won't say that again,”she tells me，and I pull her close,

pressing my nose against her hair. We are both quiet, and I don't know if I have said the right thing. So as we sit there together, shoulder to shoulder, I pray for her to be smart．I pray for her to be strong. I pray for her to find friends，work she loves, a partner who loves her, and for the world not to deprive（剝奪）her of the things that make her who she is，for her life to be easy, and for her to have the strength to handle it when it's not. And still, always，I pray that she will never struggle as I've struggled, that weight will never be her cross to bear. She may not be able to use the word in our home, but I can use it in my head. I pray that she will never get fat．

1.The underlined sentence in Paragraph 1 indicates that Lucy＿＿＿.

A. has turned against her friend J.

B. often makes fun of her friend J.

C. gets along well with her friend J.

D. has begun to compete with her friend J.

2.Why does the author want to discuss with Lucy?

A. Because she is really shocked at Lucy's rudeness．

B. Because she wants to offer some other helpful advice.

C. Because she has prepared the conversation for nine years.

D. Because she decides to tell Lucy a similar story of her own．

3.What does the author want to tell her daughter?

A. It is not easy to take the doctors' advice to eat less．

B. People shouldn't complain because life is unfair.

C. People shouldn't be blamed for their appearance.

D. She herself was once一laughed at for her appearance.

4.It can be inferred from the passage that ___ .

A. the author is a fat but good-looking woman

B. the author earns a living by writing stories

C. the author will stop loving her daughter for what she said

D. the author's daughter agreed with her from.the very beginning

C. the author allows her daughter to use the F word in her head

Directions: Read the following passage. Fill in the numbered blanks by using the information from the passage.

Write NO MORE THAN THREE WORDS for each answer.

Every person needs energy to go about the day and continue to function correctly. To get this energy, you eat, and your body changes the food into the nutrients and energy you need to survive. Your metabolism (新陳代謝) is directly related to how quickly and efficiently your body creates this energy, and if it takes too long, the food gets stored as fat. A slow metabolism will leave you with less energy and more weight than you probably desire.

Your basal metabolic rate (基礎(chǔ)代謝率) is the amount of energy your body consumes while you're resting. When people say they have a slow metabolism, they mean they have a slow basal metabolic rate. Increasing this number is possible through exercise and muscle building.

According to Metabolism-Advice. com, as your age, your basal metabolic rate will lower as your body begins to deteriorate (衰退). At the age of 30, your body will stop producing the high levels of growth hormone it previously produces. Your body senses that it's done growing at 30, so it uses the resources elsewhere. Unfortunately, that means that your muscle will deteriorate more rapidly than before. While you can’t block age's effects or your metabolism, you can fight against it with regular exercise that builds muscle.

Although muscle deteriorates quicker with age, a lack of exercise will hurt your metabolism at any age. The muscle developed during exercise is vital to maintaining a healthy body with a normal basal metabolic rate. Therefore, while cardiovascular(心血管的)exercise will burn fat during the work out, building muscle will wisely allow your body to use more calories to give you healthy energy instead of stored fat.

Another large factor that determines your basal metabolic rate is your eating habits. Metabolism-Advice. com suggests eating small meals every two to three hours. This will make sure that your metabolism is constantly working throughout your day. Another large factor is how healthily you eat. Taking in the required calories for your amount of daily activity will help keep your metabolism from lowering, but taking in too many calories may lead to fat.

Title: About slow metabolism

I . Definitions

●metabolism—how quickly and efficiently your body creates the energy for it
