NASA-s New Horizons probe(宇宙探測(cè)器)flew by Pluto(冥王星)this morning, sending back history's first up-close looks at the vast freezing-cold world. Closest approach came at 7:49 a.m. EDT. To celebrate, NASA gave out the latest photo of Pluto. It showed a reddish world with an amazing heart-shaped feature on its surface.
After today's close encounter, all the nine solar system's traditionally recognized planets have now been visited by a spaceship-a huge project begun in 1962 when NASA's Mariner 2 probe flew past Venus, a planet in the solar system. More than l,200 scientists, NASA guests and important persons, including 200 reporters, watched the flyby live at New Horizons' mission control center.
That close encounter has been a long time coming. The$723 million New Horizons mission launched in January 2006 but began taking shape in 1989. "New Horizons is'a capstone mission'," Glen Fountain, mission project manager told Space, com. "It is the first completion of the observations of our solar system. It-s giving us a new idea about how we human beings fit into the universe."
New Horizons "faced a crazy number of challenges," Stern, a driving force behind New Horizons said, "So many people stuck with this for so long. They got knocked down; they stood up. They got knocked down again; they stood up again.”
In a coincidence, today's close approach falls on the 50th anniversary of the first flyby of Mars, another planet, which was completed by NASA-s Mariner 4 spaceship.
There are no longer nine officially recognized planets, of course. The International Astronomical Union regarded Pluto as “a dwarf planet" in 2006 in a decision that remains controversial(有爭(zhēng)議的)today.
1.Which statement is TRUE according to the passage?
A. Ideas still vary in the identity of Pluto.
B. Only scientists could watch the flyby live.
C. Mars is the first planet visited by a spaceship.
D. New Horizons mission aimed to observe the solar system.

閱讀下面短文,并按照題目要求用英語(yǔ)回答問(wèn)題。
When I was growing up, I was embarrassed to be seen with my father. He was severely lame and very short, and when we would walk together, his hand on my arm for balance, people would stare. I would feel ashamed at the unwanted attention. If he ever noticed or was bothered, he never let on, nor did he say anything about it.
It was difficult to coordinate(協(xié)調(diào)) our steps—his pausing, my impatience—and because of that, we didn’t say much as we went along. But as we started out, he always said, “You set the pace, I will try to adjust to you.”
Our usual walk was to or from the subway, which was how he got to work. He went to work sick, and despite bad weather. He almost never missed a day, and would make it to the office even if others could not. A matter of pride.
When snow or ice was on the ground, it was impossible for him to walk, even with help. At such times my sisters or I would pull him through the streets of Brooklyn, NY, on a child’s sleigh to the subway entrance. Once there, he would grasp the handrail until he reached the lower steps that the warmer tunnel air kept ice-free. In Manhattan the subway station was the basement of his office building, and he would not have to go outside until we met him in Brooklyn on his way home.
When I think of it now, I wondered at how much courage it must have taken for a grown man to subject himself to such indignity and stress. And at how he did it—without bitterness or complaint.
He never talked about himself as an object of pity, nor did he show any envy of the more fortunate or able. What he looked for in others was a “good heart”, and if he found one, the owner was good enough for him.
Now that I am older, I believe that is a proper standard by which to judge people, even though I still don’t know precisely what a “good heart” is. But I know the times I don’t have one myself.
My father has been gone many years now, but I think of him often. I wonder if he sensed my unwillingness to be seen with him during our walks. If he did, I am sorry I never told him how sorry I was, how unworthy I was, how I regretted it. I think of him when I complain about incident, when I am envious of another’s good fortune, when I don’t have a “good heart”.
At such times I put my hand on his arm to regain my balance, and say, “You set the pace, I will try to adjust to you.”

The Health Benefits of Journaling
Scientific evidence supports that journaling (or keeping diaries) provides unexpected benefits. The act of writing accesses your left brain, which is analytical and rational. While your left brain is occupied, your right brain is free to create and feel. In sum, writing removes mental blocks and allows you to use all of your brainpower to better understand yourself, others and the world around you. 1.
Clarify your thoughts and feelings. Do you ever seem all mixed up inside, unsure of what you want or feel? Taking a few minutes to write down your thoughts and emotions will quickly get you in touch with your internal world.
2. By writing routinely you will get to know what makes you feel happy and confident. You will also become clear about situations and be able to recognize people who will not get on with you — important information for your emotional well-being.
Reduce stress. Writing about anger, sadness and other painful emotions helps to release your feelings. 3.
Solve problems more effectively. Typically we solve problems from a left-brained, analytical perspective. But sometimes the answer can only be found by involving right-brained creativity and intuition (直覺(jué)). 4.
Resolve disagreements with others. Writing about misunderstandings rather than worrying about them will help you understand another's point of view. 5.
In addition to all of these wonderful benefits, keeping a journal allows you to track patterns, trends and improvements and growth over time.
A. Know yourself better.
B. Achieve goals.
C. People have been studying whether the emotional release brings better sleep.
D.Writing affords the opportunity for unexpected solutions to seemingly unsolvable problems.
E. By doing so you will feel calmer and be able to stay in the present.
F. Begin journaling and begin experiencing the following benefits.
G. And you just may come up with a sensible resolution to the conflict.

Third-Culture Kids
Did you grow up in one culture, your parents came from another, and you are now living in a totally different country? If so, then you are a third-culture kid!
The term “third-culture kid” (or TCK) was coined in the 1960s by Dr. Ruth. She first came across this phenomenon when she researched North American children living in India. Caught between two cultures, they form their very own. 1. About 90 percent of them have a university degree, while 40 percent pursue a postgraduate or doctor degree. They usually benefit from their intercultural experience, which helps them to grow into successful academics and professionals.
2. In fact many hardships may arise from this phenomenon. A third-culture kid may not be able to adapt themselves completely to their new surroundings as expected. Instead, they may always remain an outsider in different host cultures.Max, for example, experienced this fundamental feeling of strangeness throughout his life as a third-culture kid. 3. While this can be a way to create a network of friends all around the world, it can be difficult for a third-culture kid like Max to maintain close friendships and relationships.
For a third-culture kid, it is often easier to move to a new foreign country than to return to their “home” country. After living in Australia and South Korea for many years, Louis finally returned to Turkey as a teenager. But she felt out of place when she returned to the country where she was born. 4. She did not share the same values as her friends’ even years after going back home.
While a third-culture kid must let go of their identity as foreigner when he/she returns, the home country can prove to be more foreign than anything he/she came across before. The peer group they face does not match the idealized image children have of “home”. 5.
As a part of the growing “culture”, TCKs may find it a great challenge for them to feel at home in many places.
A. Yet being a third-culture kid is not always easy.
B. In general, they often reach excellent academic results.
C. This often makes it hard for them to form their own identity.
D. However, their parents can help them see the opportunities of a mobile lifestyle.
E. Their experience abroad helps them to gain a better understanding of cultural differences.
F. Unlike other teens of her age, she didn’t know anything about current TV shows or fashion trends.
G. Additionally, making new friends and saying goodbye to old ones will at some point become routine for a third-culture kid.
