Read the article and select the best answer. Article: Our "Mommy and Me" time began two years ago. My next-door neighbor and fellow mother, Christie, and I were our in our front yards, watching seven children of age six and under ride their bikes up and down. "I wish I could take one of my children out alone," said Christie. Then we worked out a plan. When Christie takes one of her children out alone, I'll watch her other three. And when she watched two of mine, I will take someone out. The children were extremely quick to accept the idea of "Mommy and Me" time. Christie's daughter, McKenzie, went first. When she returned, the other children showered her with tons of questions. McKenzie was smiling broadly. Christie looked refreshed and happy. "She is like a different kid when there's no one else around," Christie shared with me quietly. With her mother all to herself, McKenzie didn't have to make any effort to gain attention. Just as Christie had noticed changes in McKenzie, I also discovered something different in each of my children during our alone times. For example, I'm always surprised when my daughter, who is seldom close to me, holds my hand frequently. My stuttering son, Tom, doesn't stutter once during our activities since he doesn't have to struggle for a chance to speak. And the other son, Sam, who is always a follower when around other children, shines a leader during our times together. The "Mommy and Me" time allows us to be simply alone and away with each child--talking, sharing and laughing, which has been the biggest gain. Every child deserves an only child at least once in a while. Question: What's the text mainly about? Options: A: The basic needs of children. B: The happy life of two families. C: The experience of the only child being with mother. D: The advantage of spending time with one child at a time.

But having a drink in space isn't as easy as it is on the earth. You have to come up with a whole new way to drink, and that' s what scientists are trying to do. "The coffee would be very hard to control in a normal cup," said physics professor Mark Weislogel. "You' d have to shake the cup toward your face and hope that some of the hot liquid floats toward your mouth. When it comes to guessing what liquids will do in new systems, we are often in the dark. " Weislogel believes that creating a big zero - gravity cup would help improve the lives of astronauts in space, so he and other researchers per formed a series of experiments with liquids on the International Space Station (ISS) to see how they move upwards on surfaces in zero gravity. In one of the tests, they placed two surfaces very close together to create a very narrow tunnel. They wanted to see if liquid would easily flow up the tunnel. In another test , the researchers tried to figure out the best angle to place the narrow tunnel at so that the liquids would travel along the corners. The end result is a cup that doesn't look like a normal coffee cup at all. One side of the cup has a very sharp angle and, in zero gravity, the liquid naturally "flows" up that angled side of the cup, right up to the drinker' s lips. The zero-gravity coffee cup is currently being tested on the ISS by astronaut Don Pettit, who worked with the researchers and helped them invent it. " As you sip , more liquid keeps coming , and you can enjoy your coffee in a weightless environment - clear down to the last drop, " said Pettit, who thinks that future humans on Mars will be using this kind of cup to drink during celebrations ! Question: What do we know about Weislogel's cup? Options: A: It looks like a very narrow tunnel. B: Each of its sides has a sharp angle. C: It is the same as the normal cup we are using. D: The liquid in it will flow to the drinkers itself.

We looked around and stopped at the sight of a small booth . It was just a big piece of cloth on the ground with a few fresh-looking oranges. A young girl was sitting on the ground, reading next to the booth. My father cleared his throat and asked,'How much are the oranges?' The girl jumped up and asked,'Oh....what?' 'How much are the oranges?' my father repeated patiently. 'Oh......two for one yuan ,'the girl answered politely. 'They are not fully grown......a bit sour ,' she added ,when my father was examining the oranges. After a while he said, 'I don 't mind if they are sour......I'll buy thirty of them.' I looked at him, baffled . Then the girl put the oranges in a bag and gave it to him. My father paid for the oranges and we left. 'Why did you buy so many oranges?' I asked my father, 'Well, she was so truthful and even told me that her oranges are sour; besides, she really enjoys studying. And look at her book-it's so old; maybe she can use the money she earned to buy a book!' I nodded my head. Just then, I felt somebody pulling my arm; I turned and recognized it was the girl from whom we bought the oranges.' Here's......here's ......your change ......' she panted , and put the money in my hand. Before we could say something ,she had already turned a corner and was out of sight. The girl and her oranges will be in my memory forever.
