Talking with people is necessary in our daily activities and it is also very important. However, we all have different styles of communicating. Some people seem to be liked by most of the people while others not! Why does this happen? The answer lies in the simple magic words of communication—Thank you, Please and Sorry!

Let’s see how and why we should use these three words:

◆ Thank you

There is not one day of our life which we spend without taking help from another person. From the time we start our day till we step into our bed for a good night’s sleep, we have taken a number of favors (恩惠). However, how many times do we thank the other person truly? Be free and generous in saying “Thank you”! It does not take away your credit (认可), but surely makes the other person happy and more willing to help you next time!

◆ Please

Often we take things for granted (想当然) and ask other people to do things for us. This does not help as others feel they are made to do these for you. A simple and sweet “please” could completely change the manner towards you.

◆ Sorry

Everyone makes mistakes, but it is quite difficult to accept it and say sorry for it. This always causes trouble in our relationship. Saying sorry does not disgrace (使丢脸) anyone, instead, puts them in a more polite position.

These three simple words can work wonders for people. If you truly use these words in your day to day communication with people, you will surely find a change in the way people respond (反应) to you and your actions.

We all enjoy the beautiful show of colours as leaves change each autumn. But did you ever wonder how and why this happens?

Leaves are nature’s food factories. Plants take water from the ground through their roots and take carbon dioxide (二氧化碳) from the air. Plants use sunlight to turn water and carbon dioxide into glucose (葡萄糖). Glucose is a kind of sugar, which plants use as food for energy and growing.

The way plants turn water and carbon dioxide into sugar is called photosynthesis that means “ putting together with light”. A chemical called chlorophyll helps photosynthesis. It gives plants their green colour. As summer ends and autumn comes, the days get shorter and shorter, and trees “know” to begin getting ready for winter.

During winter, there is not enough light or water for photosynthesis. Trees rest during this time and live on the food they store during the summer. They begin to shut down their food-making factories.

As the green chlorophyll disappears from the leaves, we begin to see yellow and orange leaves. Small amounts of these colours have been in the leaves all along. We just can’t see them in the summer, because they are covered up by the green chlorophyll.

The bright reds and purples we see in leaves are made mostly in autumn. In some trees, like maples (枫树), glucose is caught in the leaves after photosynthesis stops. Sunlight and the cool nights of autumn turn this glucose into a red colour. The brown colour of trees like oaks (橡树) is made from waste left in the leaves.

It is the mixture of all these things that makes the beautiful colours we enjoy during autumn.

【小题1】The word “chlorophyll” in the third paragraph means _______ in Chinese.

As we know, museums are building where many valuable and important objects are kept so that people can go and see them. For example, art museums are places where people can learn about v 1 cultures. More and more popular “design museums” that are opening today, however, perform quite a different role. U 2 most are museums, the design museum shows objects that are easily found in our daily life, such as fridges and washing machines.

The a 3 of design museums is that they are places where people feel familiar with the exhibits(展品). Being different from the art museum visitors, design museum visitors s 4 feel frightened or puzzled. This is partly because design museums clearly show how and why mass-products(批量产品) work and look as they do, and how design has i 5 the quality of our lives. Art museum exhibits, on the other hand, would most probably fill visitors with a feeling that there is something b 6 their understanding.

Several new design museums have opened their doors in r 7 years. Each of these museums has tried to satisfy(满足) the public’s growing interest in the field with new i 8 . London’s Design Museum, for example, shows a collection of mass-produced objects from electric typewriters to a group of Italian fish-tins. The choices open to design museums seem f 9 less strict than those to art museum, and visitors may also sense(感觉到) the humorous part of our society while walking around such exhibits as interesting and unusually attractive toys c 10 from our everyday life.
