1 . Over a hundred years ago in 1911, something strange was found in the glaciers of Antarctica. Grilffith Taylor—an Australian geologist, had discovered a blood red steam pouring out of the ice cascades（瀑布）of Talor Glacier! Popularly known as the Blood Falls, scientists had not been able to find the reason behind the blood red liquid flowing through the ice---until recently. The mystery of the Blood Falls had finally been solved.
When these falls were first discovered, scientists had believed that the red colour came from a large amount of red algae（海藻）concentrated in the water. Red algae contain a pigment（色素）which reflects red light, making the algae appear red.
This theory made sense, until it was later found that algae do not play a part in the red color of the flowing liquid at all. What really causes Talor Glacier’s waters appear blood red, is the presence of iron oxide in the liquid. The waters of the blood falls are rich in salt and iron content, and when this water comes in contact with the air, it turns red—just like rust! The water in these falls is often referred to as “brine” by scientists because of the high salt content in the water.
This reasoning behind the red colors of the falls was found back in 2003. However, the entire mystery had not yet been solved. How is it then, that the Blood Falls are not frozen?
Researchers at the University of Colorado and University of Alaska found that inside the glacier, there was a network of channels and reservoirs that move the water around. Salt water has a lower freezing temperature. In addition, when any substance undergoes a change in state, it gives off heat. Therefore, the brine actually warm itself up while it’s freezing! How this works, is that when the brine is flowing through the Talor Glacier, some of it does freeze. As a result of changing state from liquid to ice, the brine gives off heat. This heat is enough to keep the rest of the rest of the brine in liquid form, which is why it flows out of the glacier.
Incredible new chemistry facts found, any mystery solved!

2 . Measles(麻疹), which once killed 450 children each year and disabled even more, was nearly wiped out in the United States 14 years ago by the universal use of the MMR vaccine(疫苗). But the disease is making a comeback, caused by a growing anti-vaccine movement and misinformation that is spreading quickly. Already this year, 115 measles cases have been reported in the USA, compared with 189 for all of last year.
The numbers might sound small, but they are the leading edge of a dangerous trend. When vaccination rates are very high, as they still are in the nation as a whole, everyone is protected. This is called “herd immunity”, which protects the people who get hurt easily, including those who can’t be vaccinated for medical reasons, babies too young to get vaccinated and people on whom the vaccine doesn’t work.
But herd immunity works only when nearly the whole herd joins in. When some refuse vaccination and seek a free ride, immunity breaks down and everyone is in even bigger danger.
That’s exactly what is happening in small neighborhoods around the country from Orange County, California, where 22 measles cases were reported this month, to Brooklyn, N.Y., where a 17-year-old caused an outbreak last year.
The resistance to vaccine has continued for decades, and it is driven by a real but very small risk. Those who refuse to take that risk selfishly make others suffer.
Making things worse are state laws that make it too easy to opt out(决定不参加) of what are supposed to be required vaccines for all children entering kindergarten. Seventeen states allow parents to get an exemption（豁免), sometimes just by signing a paper saying they personally object to a vaccine.
Now, several states are moving to tighten laws by adding new regulations for opting out. But no one does enough to limit exemptions.
Parents ought to be able to opt out only for limited medical or religious reasons. But personal opinions? Not good enough. Everyone enjoys the life-saving benefits vaccines provide, but they’ll exist only as long as everyone shares in the risks.

3 . Shortly after the war，my brother and I were invited to spend a few days with an uncle who had just returned from abroad. He had rented a cottage in the country，although he rarely spent much time there. We understood the reason for this after our arrival: the cottage had no comfortable furniture（家具）in it；many of the windows were broken and the roof leaked（渗漏），making the whole house terrible.
On our first evening，we sat around the fire after supper listening to the stories which our uncle had to tell of his many adventures in distant countries. I was so tired after the long train journey that I would have preferred to go to bed；but I could not stand missing any of my uncle's exciting stories.
He was just in the middle of describing a rather terrifying experience he had once had when there was a loud crash from the bedroom above，the one where my brother and I were going to sleep.
"It sounds as if the roof has fallen in！"cried out my uncle，with a loud laugh.
When we got to the top of the stairs and opened the bedroom door，we could see nothing at first because of the thick clouds of dust which filled the room. When the dust began to clear，a strange sight met our eyes. A large part of the ceiling had fallen down，falling right onto the pillow（枕头）on my bed.
I was glad that I had stayed up late to listen to my uncle's stories，otherwise I should certainly have been seriously injured，perhaps killed.
That night we all slept on the floor in the sitting room downstairs，not wishing to risk our lives by sleeping under a roof which might at any moment fall down on our heads. We left for London the very next morning and my uncle gave up his cottage in the country. This was not the kind of adventure he cared for either！
1. Why did the uncle seldom spend much time in the country cottage？| A．Because the roof of the cottage had fallen. |

| C．something strange stopped them |
| D．it was a mess inside |
| A．he did not miss the exciting stories |

| C．he had a lucky escape |
| D．he saw a strange sight |
| A．Adventurous and good at storytelling. |
| B．Humorous and good at making jokes. |
| C．Dependable and generous with money. |
| D．Thoughtful and sensitive to danger. |
Born to a model mom and a suit maker dad, fashion was actually in my blood. I always had a strong desire to dress in a certain way and to stand out from the crowd.
I made my own toys when I was a young child and sewed my first skirt at just 10 years old. A friend’s mother took one look at my skirt and told me that I should be a patternmaker. In high school I started making my own clothes, mostly changing other things because I never liked anything how it was when I bought it. During the last two years of school, I worked part-time for a small business that made hand-painted silk clothing and bags. The owner became the teacher who got me into design in the first place. Another useful bit of work experience then came when I worked at a showroom during fashion week and found it very exciting. From there I worked at a top clothing store while I got my business started.
For my business I started out with the idea that everything I did would be hand-made and one-of-a-kind, specially made for one individual who hopefully had the same tastes as me. Every morning I jumped out of bed, went to my studio and worked on my projects. This just showed how enthusiastic I felt about my work. And at night I even dreamed of new designs!
Fashion design is functional art. What I mean is that it’s something close to you and something you can touch and feel, and actually interact with. My advice to any young person who wants to be a fashion designer is to get the basic skills early on, such as sewing and pattern-making. Even if you end up specializing, it’s really important to understand all aspects of design in order to make high-quality clothes.
Also, if you dream of having your own clothing line, the best thing to do is start wearing your clothes. You have to try and do this because that’s the way you’re going to develop something that’s all yours and unlike anyone else’s. I passionately believe that the right clothing can make people feel better and give them more confidence.

6 . Should we allow modern buildings to be built next to older buildings in a historic area of a city? In order to answer this question, we must first examine whether people really want to preserve the historic feel of an area. Not all historical buildings are attractive. However, there may be other reasons—for example, economic (经济的) reasons—why they should be preserved. So, let us assume that historical buildings are both attractive and important to the majority of people. What should we do then if a new building is needed?
In my view, new architectural styles can exist perfectly well alongside an older style. Indeed, there are many examples in my own home town of Tours where modern designs have been placed very successfully next to old buildings. As long as the building in question is pleasing and does not dominate (影响) its surroundings too much, it often improves the attractiveness of the area.
It is true that there are examples of new buildings which have spoilt (破坏) the area they are in, but the same can be said of some old buildings too. Yet people still speak against new buildings in historic areas. I think this is simply because people are naturally conservative(保守的)and do not like change.
Although we have to respect people’s feelings as fellow users of the buildings, I believe that it is the duty of the architect and planner to move things forward . If we always reproduced what was there before, we would all still be living in caves. Thus, I would argue against copying previous architectural styles and choose something fresh and different , even though that might be the more risky choice.

Lewis and his co-workers carried out their study by videotaping (录像) the families while they ate ordinary meals in their own homes. They found that parents with small families talk actively with each other and their children. But as the number of children gets larger, conversation gives way to the parents’ efforts to control the loud noise they make. That can have an important effect on the children. “In general the more question-asking the parents do, the higher the children’s IQ scores,” Lewis says. “And the more children there are, the less question-asking there is.”
The study also provides an explanation for why middle children often seem to have a harder time in life than their siblings (兄弟姐妹). Lewis found that in families with three or four children, dinner conversation is likely to center on the oldest child, who has the most to talk about, and the youngest, who needs the most attention. “Middle children are invisible,” says Lewis. “When you see someone get up from the table and walk around during dinner, chances are it’s the middle child.” There is, however, one thing that stops all conversation and prevents anyone from having attention: “When the TV is on,” Lewis says, “dinner is a non-event.”

This tension between what we feel we can have and "what were seemingly able to have is the niggling suffering, the anxiety we feel. This is where we usually think it's easier to just give up. But we're never meant to let go of the part of us that knows we can have more. The intelligence behind that knowing is us—the real us. It's the part that believes in life and its possibilities. If you drop that, you begin to feel a little "dead" inside because you're dropping "you".
So, if we have this capability but somehow life seems to keep us stuck, how do we break these patterns?
Decide on a new course and make one decision at a time. This is good advice for a new adventure or just getting through today's challenges.
While, deep down, we know we can do it, our mind—or the minds of those close to us—usually says we can't.
That isn't a reason to stop, it's just the mind, that little man or woman on your shoulder, trying to talk you out of something again. It has done it many times before. It's all about starting simple and doing it now.
Decide and act before overthinking. When you do this you may feel a little, or large, release from the jail of your mind and you'll be on your way.
1. It can be inferred from the first two paragraphs that we should .
| A．slow down and live a simple life |
| B．be careful when we choose to change |
| C．stick to our dreams under any circumstances |
| D．be content with what we already have |
| A．To focus on every detail. |
| B．To decide and take immediate action. |
| C．To listen to those close to us. |
| D．To think twice before we act. |
| A．Escape from your punishment |
| B．Realization of your dreams. |
| C．Freedom from your tension. |
| D．Reduction of your expectations. |
| A．It's easier than we think to get what we want. |
| B．It's important to learn to accept sufferings in life. |
| C．It's impractical to change our way of thinking. |
| D．It's harder than we expect to follow a new course. |
