We have always been interested in the moon. 2000 years ago people already knew it moved around the earth and where it would be in the sky at different times of the year. At that time, everything about the moon was learned by watching it carefully in the sky.

    When scientists could use telescopes to study the moon more closely, their ideas began to change. They could see the moon was made of rocks. Most scientists thought moon rocks would be different from those on Earth. This was because they believed the moon had once been a planet that had been caught in the earth's gravity (引力) millions of years earlier.

    In 1969 moon rocks were finally brought to the earth and studied. Much to their surprise, scientists found that, except for water, the moon and the earth were made of the same things. Once again new ideas were needed for this new information.

    After years of study, most scientists now think that the moon was once part of Earth. They believe very early in its history, maybe 4 million years ago, something about the size of Mars hit Earth. This sent billions of rocks into space around our planet. These rocks slowly joined together and after many years became the moon.

    However, in the future, even though our ideas about the moon may change again, we will still be interested in it.

    After years of research and testing, the hybrid car was developed and put on the market. It's an interesting and exciting new improvement in today's world as we look for better ways to protect the quality of the air we breathe and save our natural resources.

    The quality of our air is affected by many different things. But one of the largest sources of air pollution is the burning of fossil fuels such as coal and gasoline which is used to power a car's engine. The EPA has set national standards to help control the level of harmful pollutants sent off into the air, and the automobile industry has acted by producing a hybrid car that uses less gas and therefore causes less pollution.

    A hybrid car is a combination of a regular car that runs on gasoline and an electric car that is battery powered. Some people tend to think that since the hybrid car is partially electric, you have to plug it in to charge it. But that's not how it works. The 144 volt battery pack is actually recharged through the energy that is produced when the car's brakes are used. This is referred to as "regenerative braking", because it produces electricity.

    Although the hybrid car still runs on gasoline most of the time, this helps it use less gas than a regular car. When the driver stops at a traffic light, the engine automatically shuts off to save fuel. Then, as soon as the driver puts the car in gear and touches the gas pedal, the engine starts back up.

    Have you ever ridden in a car with someone who ran out of gas? That probably wouldn't happen if you were riding in a hybrid car. It flashes a warning on its computer screen that says, "I am low on gas". When it completely runs out, the warning reads, "YOU ARE NOW OUT OF GAS!" Then the electric power supply kicks in to let the driver travel a few more miles to a gas station.

The Chinese cheongsam, also known as qipao, is a traditional dress that first appeared in the early 20th century in Shanghai. It has become a symbol of Chinese culture and is worn by women around the world.

The cheongsam hugs the curves(曲线) of the body and is mostly made of silk or cotton. It's typical with a high collar(领), short sleeves(袖) and a short cut on the side of the skirt to make movement easy.

The cheongsam was first worn by wealthy women in Shanghai as a way to show their social positions and wealth. But it quickly became popular among all classes of women as daily clothes. During the 1920s and 1930s, the cheongsam experienced changes and became fitter and better designed with fashionable elements(元素). Nowadays, designers are creating new styles to follow modern fashion.

Today, the cheongsam is often worn for formal situations such as ceremonies, celebrations and cultural events in China. One of the most popular looks of the cheongsam is Anna Wong, a Chinese famous movie star. She often wears cheongsams on and off screen. Her look helps to make the dress win popularity in Hollywood and around the world.

The cheongsam is not just a symbol of fashion, but also of Chinese culture and history. It brings out that Chinese people can always keep up with  changing fashion over years.

The cheongsam has stood the test of time. It will continue to catch eyes of the public and give ideas to people for years to come.

The film Postmen in the Mountains shows a traditional Chinese father's {#blank#}1{#/blank#}(不作声的) love. At the beginning of the film, a {#blank#}2{#/blank#}(英俊的) young man walks fast {#blank#}3{#/blank#}(沿着) a mountain road and an older man with a strict face follows him. The film shows a touching story about the love between father and son. 

The father served as the {#blank#}4{#/blank#}(邮差) for this area for many years. Because of the busy work, he was often {#blank#}5{#/blank#}(缺席的) from lots of important moments of his family. As a result, his son {#blank#}6{#/blank#}(很少) saw him. When the son grew up, he took over his father's {#blank#}7{#/blank#}(职位). The father went with his son on his first day of work. We realise that they start to see into each other's hearts. This time, the son {#blank#}8{#/blank#}(把……带至) his father across a cold river. This action brings back the father's memory of carrying the son on his back. We can see his {#blank#}9{#/blank#}(眼泪) quietly running down his face. 

In fact, the father always hides his care in his heart. He doesn't give {#blank#}10{#/blank#}(拥抱) or kisses to his son, but his love is like a mountain. It is always there. 

As a student, you may be required to write reviews.{#blank#}1{#/blank#} Writer Luisa Plaja offers her suggestions on how to write a good review of a book. 

Start with a couple of sentences describing what the book is about. As a common rule, try to avoid writing in detail(细节) about anything that happens from about the middle of the book. If the book is part of a series(系列), it can be useful to talk about this. 

{#blank#}2{#/blank#} Pay attention to your thoughts and feelings about the story and the way it was told. You could try answering a couple of the following questions:

Who was your favourite role, and why?

What was your favourite part of the book, and why?

Did the book make you laugh or cry?

Did the story keep you turning the pages?

Talk about anything you disliked about the book.{#blank#}3{#/blank#} For example: Did you wish the ending wouldn't be magic because you found it surprising? Did you find it difficult to care about a main character, and did you know why? Did the story focus on a topic you aren't interested in?

{#blank#}4{#/blank#} Summarise (总结) some of your thoughts on the book by suggesting the type of readers you'd introduce the book to. For example: younger readers, older readers, fans of relationship drama, mystery stories or comedy. 

Write a title for the text (not more than 5 words). {#blank#}5{#/blank#}
