I have never been to a cooking school. I learned cooking from my mother because she was really interesting in teaching me how to cook. The main reason for this was because my mother didn’t know how to cook something when she got married.
My grandmother never allowed her stay in the kitchen. At the age of 25, my mother started cooking, it was very hard for her. Therefore, she had to take a few cooking class to prepare our meals. After having that experience, she has decided to teach me how to cook.
I remember I always help my mother when I was with her in the kitchen enjoy cooking. Nowadays, I am thank for that experience.

Many students have to live with roommates while going to school or university. Having a roommate can be one of the best experiences, or easily one of the worst. 1.
Follow these five tips to avoid the common mistakes that make good roommate relationships worse.
Talk things out. 2. If something happens, sit down with your roommates and have a face-to-face conversation. Complaining about your roommates behind their backs creates nothing but awkward situations and general unhappiness.
3. Some roommates become the best of friends, and some don’t. Don’t put pressure on yourself or your roommate to reach this level, especially when you first meet. Remember, you are trying to make a new friend, not scare your roommate away. And if your roommate doesn’t end up being your best friend, there is no need to worry about it.
Clean up after yourself. Or at least, keep your mess on your side. 4. But being considerate with where you put your own stuff will help you avoid the arguments.
Ask before you take. This applies to food, clothes, supplies and anything else that you don’t own. 5. Even if you both agree to share everything you should still ask.
A. Don’t expect to be best friends.
B. Communication is of vital importance.
C. You don’t need to keep the room clean and organized all the time.
D. Rooms can be really easy for a mess to pile up.
E. If you want to have a good relationship with your roommate, it all starts with you.
F. Not all roommates can become your best friends.
G. Show your roommate that you have respect for his or her belongings.
Batteries can power anything from small sensors to large systems. While scientists are finding ways to make them smaller but even more powerful, problems can arise when these batteries are much larger and heavier than the devices themselves. University of Missouri(MU) researchers are developing a nuclear energy source that is smaller, lighter and more efficient.
“To provide enough power, we need certain methods with high energy density(密度)”，said Jae Kwon, assistant professor of electrical and computer engineering at MU. “The radioisotope(放射性同位素) battery can provide power density that is much lighter than chemical batteries.”
Kwon and his research team have been working on building a small nuclear battery, presently the size and thickness of a penny, intended to power various micro / nanoelectromechanical systems (M/NEMS). Although nuclear batteries can cause concerns, Kwon said they are safe.
“People hear the word ‘nuclear’ and think of something very dangerous,” he said, “However, nuclear power sources have already been safely powering a variety of devices, such as pace-makers, space satellites and underwater systems.”
His new idea is not only in the battery’s size, but also in its semiconductor(半导体). Kwon’s battery uses a liquid semiconductor rather than a solid semiconductor.
“The key part of using a radioactive battery is that when you harvest the energy, part of the radiation energy can damage the lattice structure(晶体结构) of the solid semiconductor,” Kwon said, “By using a liquid semiconductor, we believe we can minimize that problem.”
Together with J. David Robertson, chemistry professor and associate director of the MU Research Reactor, Kwon is working to build and test the battery. In the future, they hope to increase the battery’s power, shrink its size and try with various other materials. Kwon said that battery could be thinner than the thickness of human hair.
1.Which of the following is true of Jae Kwon?
A. He teaches chemistry at MU.
B. He developed a chemical battery.
C. He is working on a nuclear energy source.
D. He made a breakthrough in computer engineering.
2.Jae Kwon gave examples in Paragraph 4_________.
A. to show chemical batteries are widely applied.
B. to indicate nuclear batteries can be safely used.
C. to describe a nuclear-powered system.
D. to introduce various energy sources.
3.Liquid semiconductor is used to _________.
A. get rid of the radioactive waste B. test the power of nuclear batteries.
C. decrease the size of nuclear batteries D. reduce the damage to lattice structure.
