We need to be responsible(有责任心的)for our environment. Being a frugal consumer(节俭的消费者)is one way to help. But, what exactly does that mean?

Use it up

 ① ____

You do not always need to have new things. Suppose there are holes in your socks. Mend them and wear them longer. You don't have to have the latest telephone until the old one doesn't work anymore. Then you get a new one. Think twice before replacing something that still works.

②_________

When something you want is not on hand look for something else that you already have to take its place. Suppose you are preparing your lunch for tomorrow and want a better sandwich. However, there is not any butter in your home. Have a cheese sandwich instead so that you can use all of the cheese. With a little thought, you can make something do, instead of buy something new.

Do without

Think about all those things that you would like to have. Do you really need them? How long will you really play with that new toy? Make a list of things that you want. Delete the things that you don't really need, so you can save a lot of resources(资源).

School Lunches from around the World

   Do you wonder what children are eating for lunch across the world? Take a look at different school lunches and learn something about kids'school lives across the world.

   In Japan, 99% of elementary school(小学)students and 82% of junior high school students eat kyushoku (school lunch). It includes a bottle of milk, a bowl of rice, usually some types of fish, a salad, some kinds of soup, usually with tofu and vegetables, and a piece of fruit.

   In the United States kids have hamburgers and chips for lunch. Those school lunches are making the kids so fat that many are unable to meet the physical fitness standards(标准). The good news is that Improving Nutrition(营养) for American's Children Act was recently passed. That will help to make school lunches more nutritional(有营养的).

   In Beijing, school lunches are usually provided from home. A food service worker picks up the fresh meals from home and sends them to schools.

Information Card

    In order to learn how the students in our school spend money, we made a survey by asking them some questions. First, we asked them how much money they spent last month. And then we asked how much money they spent on snacks, books, movies, computer games, phones, transportation and other things last month. Our maths teacher helped us make a graph（图表） of their answers as follows.

    In our school, each student spent about{#blank#}1{#/blank#} yuan on average（平均）last month. According to the graph made by our{#blank#}2{#/blank#} teacher, we know how much money the students spent on different things in our school. As the graph shows, they spent most on{#blank#}3{#/blank#} , covering 22% of all. It was followed by computer games and movies. Each of them was {#blank#}4{#/blank#}  . But to our surprise, he students spent {#blank#}5{#/blank#} on books, only 6%.

    When it comes to the letter grade on your test or homework, you might notice that there is no letter E. Have you ever thought about why that is so?

    In the A, B, C, D and F grading system, the first four letters are typically considered passing grades. An F in this system simply stands for "fail". The word "fail" happens to start with the letter F, which seems to leave out the letter E.

    The first college in the US to use a letter grading system like the ones we use today is Mount Holyoke College. In 1897, they began to use the following grading scale;

    A: 95-100% (excellent)         B: 85-94% (good)      C: 76-84% (fair)

    D: 75%( nearly passed)         E: below 75% (failed)

    We can see the inclusion of E instead of F.

    Gradually, the letter grading system became more popular all over the US. However, many schools decided to drop the E grade and go straight to F. There is no evidence(证据) to really support this, but one possible explanation is that teachers were worried that some students and parents might mistake E for "excellent".

    Why do we have letter grades? Well, part of the reason is that they made grading simpler during a time of great change for schools. As the 20th century began, growing cities and an increase in immigration led to larger school classrooms. Most teachers at that time thought this new letter grading system was an easy, fair and clear way to grade students.

    Today, more and more people think that letter grades don't fully show students' learning. However, as teachers try to improve grading methods, many parents continue to prefer the letter grades they got as kids, as they are familiar and easy for parents to understand. So while they might not be perfect, the letter grades probably aren't going away any time soon.
