Food safety is a problem in all places around the world and people in different areas of the world prepare foods in different ways. The WHO released five simple rules for preparing food in a safe way.{#blank#}1{#/blank#}

    Key 1: Keep clean.

    The first key tells about the importance of washing. People should wash their hands often—before touching food, while they are preparing food, and any time after they go to the toilet. People should wash all surfaces and equipment used for preparing food.{#blank#}2{#/blank#}

    Key 2:{#blank#}3{#/blank#}

    People should separate raw, or uncooked food from foods that are already cooked and foods that will not be cooked. People should store raw meat, chicken, and fish in containers, or in separate areas. Raw foods should not touch prepared foods.

    Key 3: Cook completely.

    People should cook eggs and meat, like birds, seafood, and animals, especially carefully. These foods may carry more micro-organisms than other foods. Food like soup must be boiled for at least a minute to make it be cooked completely. It is also important that people re-heat cooked food completely.

    Key 4: Keep food at safe temperatures.

    When people are finished with eating, they should keep the left food in a refrigerator below 5℃ and shouldn't store it for too long. At room temperature, about 20℃, the amount of micro-organisms can increase very quickly.{#blank#}4{#/blank#}They cannot grow as quickly in a very hot or very cold environment.

    Key 5: Use safe water and raw materials.

    {#blank#}5{#/blank#} Damaged or old food may develop harmful chemicals as it gets older.

A. Eat cooked food immediately, while it is still hot.

B. They call these rules the “Five Keys to Safer Food.”

C. Separate raw and cooked.

D. People should use safe water and choose fresh foods.

E. Keeping everything clean helps people to avoid micro-organisms.

F. People should also protect cooking areas and food from insects and animals.

G. But temperatures above 60℃ or below 5℃ control the growth of micro-organisms.

    Developing good teacher-student relationships

    We all have our favorite teachers-those who seem truly interested and treat us as intelligent beings. But what about teachers we don't know as well (or even don't like much)?{#blank#}1{#/blank#}

    First, do the obvious stuff: show up for class on time, with all assignments completed. Be polite, be respectful, and ask questions.

    {#blank#}2{#/blank#} Obviously, your teachers are really interested in their subjects or they wouldn't have decided to teach them! Showing the teacher that you care sends the message that you are a dedicated student.

    You can also schedule a private conference during a teacher's free period. Use this time to get extra help ask questions, inquire about a career in the subject, or talk about your progress in class.{#blank#}3{#/blank#}

    What to do if you don't get along

    Before you try to get out of a class to escape a teacher you don't like, here are a few things you can try to make a difficult relationship work:

    Ask yourself, “What can I learn from this teacher?” Even if you don't worship his or her personality or lectures, dig deep until you find a subject in which your teacher is very knowledgeable.{#blank#}4{#/blank#}

    Talk to students who are doing well in the class and ask them for tips, tools, and a plan of action to get along with the teacher better.

    If your relationship problems can't be solved in school, then it's time to tell your parents. Let them meet with your teacher and try to work it out.

    Teachers are there for more than just homework, and they know about more than just their subject matter.{#blank#}5{#/blank#}Undoubtedly, there will be a few teachers along the way who you'll always remember-and who might change your life forever.

A. Show an interest in the subject.

B. Teachers sense when your only motivation is to get special treatment.

C. They can help you learn how to function as an adult and a lifelong learner.

D. You can do lots of things to get a good connection going with your teacher.

E. Focus of that part of the teacher's personality, and use it as a tool for learning.

F. Here are some things to avoid when trying to establish a relationship with your teacher.

G. You may be surprised to learn that your teacher is a bit more relaxed one-on-one than when lecturing in front of the whole class.

    When I was young, my friends and I often played baseball in an alley(小巷) behind our home. A woman named Mrs Shinas owned a tiny house nearby, and she used to watch us play from her window.{#blank#}1{#/blank#} we all thought that she was mean.

    She had a big trained dog and whenever one of our baseballs rolled in its direction, Mrs Shinas would send the dog to catch it.{#blank#}2{#/blank#} soon we ran out of balls.

    In those days, I used to water our lawn each day. One day as I stood watering our small lawn, I noticed that Mrs Shinas' lawn looked a little dry. It took only a few more minutes to water it, so I did it.{#blank#}3{#/blank#}

    When autumn came that year, I also helped gather up the leaves on Mrs. Shinas' yard. As I was doing this one day, she invited me to sit in her living room. She gave me a cookie and a glass of milk. As I sat there eating the cookie, she showed me her collection of paintings. {#blank#}4{#/blank#}that surprised me a lot. It was the first conversation I had ever had with her.

{#blank#}5{#/blank#} She went into her kitchen and returned with a box. In it were all the balls that her dog had taken. She handed me the box, said "thank you" and smiled. I realized she had a kind heart. I also learned that when we serve others, we are showing them that we love them.

Tips for procrastinators (拖延者)

Home libraries can be a dynamic expression of the owner's personality. Creating a home library is a fun way to display your interests while establishing a special space for reading.

While there's no right or wrong way to design a library, the questions can be puzzling, especially to someone with hundreds or thousands of books. How do I organize?{#blank#}1{#/blank#} We'll discuss how to build a home library that works for you.

What room should I use for my home library?{#blank#}2{#/blank#} While reading in a room with big windows and lots of light is refreshing, storing books in natural light is harmful to them. Basements heavy with humidity (湿气) will cause mold (霉菌) and attract insects.{#blank#}3{#/blank#}

When you started using the public library, you probably learned about Melvil Dewey and his system for ordering libraries. The Dewey Decimal Classification System has ten broad categories for organizing books, including philosophy, religion and the arts.{#blank#}4{#/blank#} For example, when you want a book on modern art, you head to the 700th block. Larger libraries, such as those at universities, tend to use the Library of Congress Classification System, because it offers a more specific array of subjects for categorization, adding subjects such as medicine and law for a total of 21categories.

{#blank#}5{#/blank#} Your home library may or may not be as large as your local public library, but a good system of organization will still help you find the book you want quickly. You could take a page from Dewey and the Library of Congress and sort books by subject matter. Sections for subjects such as history, technology or fiction might make their retrieval (检索) easier. This system will also allow you to highlight a particular passion, such as an extensive collection of World War II history,

A. How do I get everything to fit?

B. Each category is assigned a number.

C. Almost everybody wants a home library.

D. A good system of organization is the key.

E. In addition, basements are likely to be flooded.

F. Almost any room will do with a few exceptions.

G. The size of a home library depends on how much space you can spare.
