              Almost every Chinese can recite the two lines of the famous poem, "Every grain on the plate comes from hard work." But sadly, many of us don't get the real meaning of these lines: Don't waste food.
              News 1+1,a famous CCTV program, reported that food Chinese people throw away every year is enough to feed 200million people for a year.
              Do we have too much food? No. According to the UN World Food Program, there were 925million hungry people around the world in 2016, especially in developing countries. Six million children die of hunger every year.
              Chinese people are well known for being generous(慷慨的). Many even feel that they lose face if their guests have eaten all the food on the table.
              Luckily, a number of people have realized the importance of saving food. Li Hong, a waitress in a restaurant in Nanjing, got fired( 开除) because she took some leftover food home for her son. Many people stood by her side and criticized the waste of food.
              What should we do in our daily lives to waste less food. Here are some tips:
              ★ Don't order too much in a restaurant. Only order as much as you want to eat. If you cannot eat all the food you ordered, take the rest of it home.
              ★ Don't be too picky(挑剔) about food. Some food may not taste great, but your body needs it.
              ★ Keep an eye on what food you have at home. Don't buy too much, especially for vegetables and fruit.

              Have you ever heard someone use the phrase"once in a blue moon"?People use this expression to describe something that they do not do very often.For example,someone might say that he tries to avoid eating sweets because they are unhealthy,but will eat chocolate"once in a blue moon".Or someone who does not usually like to go to the beach might say"I visit the shore once in a blue moon."While many people use this phrase,not everyone knows the meaning behind it.
              The first thing to know is that the moon itself is never really blue.This is just an expression.In fact,the phrase"blue moon"has to do with the shape of the moon,not the color.
              As the moon travels around the earth,it appears to change shape.We connect names with certain shapes of the moon.For example,when we can see a small part of the moon,it is called a crescent moon.A crescent is a shape that looks like the tip of a fingernail(指甲尖).When we cannot see the moon at all,it is called a new moon.When we can see the whole moon,it is called a full moon.Usually,there is only one full moon every month.Sometimes,however,there are two full moons in one month.When this happens,the second full moon is called"a blue moon".
              Over the next 20years,there will only be 15blue moons.So you can seldom see a blue moon. This fact has led people to use the expression"once in a blue moon"to describe things they don't often do in their lives.
              (1) Which of the following would be a good example of using the phrase"once in a blue moon"? ______
              A. Simon often tells jokes.Simon tells jokes once in a blue moon.
              B. Tom seldom remembers to do exercise.Tom does exercise once in a blue moon.
              C. Mary likes to go shopping every weekend.Mary goes shopping once in a blue moon.
              D. Cindy hates to stay up,but she stays up every day.Cindy stays up once in a blue moon.
              (2) When does a blue moon happen in nature? ______
              A. When the moon has a blue color.
              B. When we cannot see the moon at all.
              C. When there are two full moons in one month.
              D. When we can only see a small part of the moon.
              (3) Which of the following is another example of something that has a crescent? ______
              A. The letter"O".
              B. The letter"M".
              C. The letter"H".
              D. The letter"C"
              (4) How often will a blue moon happen over the next twenty years? ______
              A. Once a year.
              B. Less than once a year.
              C. More than once a year.
              D. At least twice a year.
              (5) What does the underlined part"This fact"in the last paragraph refer to? ______
              A. A blue moon is not often seen during the years.
              B. The moon appears to change its shape.
              C. The moon itself is never really blue.
