The Future Stars
General introduction
The Future Stars was set up in 1988 as a non-profit service center for child development devoted to providing quality childcare in a loving and educational environment for children 6 weeks to 6 years of age. Our funds mainly come from public donations.
A healthy curiosity about learning is the most important quality for early childhood development. We aim at offering high quality developmentally age-appropriate activities for early childhood, the most Important time of child development, so that they can do better after they start formal schooling.
Hours of operation
Childcare will be provided for the child from 7:00 am to 6:00 pm Monday through Friday except for holidays. Children may not arrive before 7:00 am or remain after 6:00 pm. Should an emergency arise, the parent should immediately make us know in consideration of our work arrangements. A late charge of $ 1.00 per minute will be assessed if the child is not picked up by 6:05 pm. Charges for these services are to be paid directly to the staff person that has been looking after your child until your arrival, not to the center. Failure to pay late charges may affect continued services with the center.

Driving to a friend's house on a recent evening, I was attracted by the sight of the full moon rising just above my friend’s rooftops. I stopped to watch it for a few moments, thinking about what a pity it was that most city people? Myself included? Usually miss sights like this because we spend most of our lives indoors.
My friend had also seen it. He grew up living in a forest in Europe, and the moon meant a lot to him then. It had touched much of his life.
I know the feeling. Last December I took my seven-year-old daughter to the mountainous jungle of northern India with some friends. We stayed in a forest rest-house with no electricity or running hot water. Our group had campfires outside every night, and indoors when it was too cold outside. The moon grew to its fullest during our trip. Between me and the high mountains lay three or four valleys. Not a light shone in them and not a sound could be heard. It was one of the quietest places I have ever known, a bottomless well of silence. And above me was the full moon, which struck me deeply.
Today our lives are filled with glass, metal, plastic and fibre-glass. We have televisions, cell phones, pagers, electricity, heaters and ovens and air-conditioners, cars, computers.
Struggling through traffic that evening at the end of a tiring day, most of it spent indoors, I thought: before long, I would like to live in a small cottage. There I will grow vegetables and read books and walk in the mountains And perhaps write, but not in anger. I may become an old man there, and wear the bottoms of my trousers rolled and measure out my life in coffee spoons. But I will be able to walk outside on a cold silent night and touch the moon.
1.The best title for the passage would be______.
A. Touched by the moon B. The pleasures of modern life
C. A bottomless well of silence D. Break away from modern life
2. What impressed the writer most in the mountainous jungle of northern India?
A. No modern equipment B. Complete silence.
C. The nice moonlight D. The high mountains

B. tell us that people greatly benefit from modern life
C. explain that people have less chances to enjoy nature
D. show that we can also enjoy nature at home through them

Each type of oil has what is called a“smoke point. ”The smoke point is the specific temperature at which the oil starts to break down, or in more technical terms, its molecular structure begins to change. These molecular changes result in； changes in flavor, as well as W ww.k s 5u.com changes in nutritional value，specifically，the nutritional value of the oil starts to reduce；changing what once may have been considered an especially healthy oil，like Olive，into one that is unhealthy．
The higher an oil’s smoke point is，the higher the temperature of the oil can be．As a result, each type of oil should be used for the cooking method that is most appropriate to its individual smoke point and heat tolerance. Here is a quick guide for the next time you reach for your favorite oil．
| Heat During Cooking | Oil | Best Use |
| Low to Moderate | Coconut | Baking (low heat ) Light Sauteing Pressure Cooking Salads |
| Corn | ||
| Olive | ||
| Peanut | ||
