When treating some friends to dinner, we Chinese often say, “The dishes are not good. Please forgive me.” In fact, it is a Chinese way of {#blank#}1{#/blank#} (be) modest. {#blank#}2{#/blank#} he really means is that all the dishes here are really wonderful! What he really hopes is compliment from the guests! But {#blank#}3{#/blank#} English would not understand it at all! Now that it is not very good, why should you present the dishes in front of us? The English would say to their guests “ Enjoy yourselves!” when eating and “hope you've enjoyed!” after eating.

    While {#blank#}4{#/blank#} (eat), we Chinese often say to the guests, “Eat slowly.” This would be very {#blank#}5{#/blank#} (puzzle) to the foreigners: Am I eating very violently? Am I eating too {#blank#}6{#/blank#} or too much?

    And now comes the end of the dinner when your guests {#blank#}7{#/blank#} (leave). The Chinese would say, “Walk slowly!” This is a very polite saying in Chinese, but will also be confusing to the foreigners: why can't I walk fast? Does it matter {#blank#}8{#/blank#} I walk slowly or not? Are you worrying that I may fall over? {#blank#}9{#/blank#} change your words {#blank#}10{#/blank#} a simple “Bye!” or “See you next time!”

    You may like at least some kind of music. But the problem is that, in lots of places, you're made {#blank#}1{#/blank#}(hear) somebody else's choice of music. Say you've just landed at an airport, where the background (背景) music may be played loudly. When you are {#blank#}2{#/blank#} the way to you hotel, there may be another kind of music {#blank#}3{#/blank#} (switch) on by the taxi driver. Then you go out to dinner and end up in a restaurant,{#blank#}4{#/blank#}owner thinks music will help make you eat more and spend more. Then a person {#blank#}5{#/blank#}(play) the violin comes around. This is called the “music wallpaper” and its purpose is to make you consume more. In a word, you find {#blank#}6{#/blank#} hard to find a quiet public place without music.

    Noise pollution may be {#blank#}7{#/blank#}(harm) to our hearing. It's also bad for some of our daily {#blank#}8{#/blank#} (activity).

    The fact {#blank#}9{#/blank#} you can't see, taste or smell noise may help explain why it has not received as much attention as other kinds of pollution, such as air pollution or water pollution. Many of us fail to realize we {#blank#}10{#/blank#} (surround) by too much noise. As a result, harm is done to our health without us being aware of it.

    Qingdao lies in the east of Shandong Province. As we all know, it is an important port city and it is an economic and {#blank#}1{#/blank#}(culture)center. It is also home to the Tsingtao Brewery Co. Ltd. and the {#blank#}2{#/blank#}(large)international beer festival in China. Of course, Qingdao is a very beautiful city, too. Many places around the city are well worth {#blank#}3{#/blank#}(visit).Every year, the festival {#blank#}4{#/blank#}(hold)on schedule. Millions of visitors {#blank#}5{#/blank#} come from the world go to the city during the festival.

    It is very convenient to go to Qingdao. It is {#blank#}6{#/blank#}(rough)650 kilometers from Beijing with an average travel time of one hour and 10 minutes by air and five hours by high-speed train. It is about 740 kilometers from Shanghai, and it {#blank#}7{#/blank#}(take)about one hour and 25 minutes by air. There are also frequent direct {#blank#}8{#/blank#}(flight)from Qingdao to the Republic of Korea and Japan. The city's airport is connected {#blank#}9{#/blank#} 66 domestic cities and 12 overseas cities, with a great number of planes arriving {#blank#}10{#/blank#} taking off each week. Warmly welcome to Qingdao!

    In Hebei Province lies a vast forest called Saihanba. This green Great Wall, {#blank#}1{#/blank#} at its peak during the Qing Dynasty covered thousands of hectares, had by the 1950s {#blank#}2{#/blank#}（virtual）disappeared. This allowed sand to blow into Beijing from the northern deserts.

    Saihanba is a combination of Chinese and Mongolian, {#blank#}3{#/blank#}（mean）“beautiful highlands". Until the Qing Dynasty, it was a royal hunting land because of its cool summer weather and beautiful surroundings. However, most of the area had turned into a desert by the end of the Qing Dynasty.

    In fact 56 years ago there was only one tree left. But without that tree, there {#blank#}4{#/blank#}（be）no miracle of Saihanba today. In the early 1960s, over 350 foresters {#blank#}5{#/blank#}（send）to this area to fight the desert. They were required {#blank#}6{#/blank#}（rebuild）the forest in Saihanba. Few people, including the foresters themselves, believed they would succeed.

Their doubt disappeared, however, when they found the 200-year-old tree, swaying alone in {#blank#}7{#/blank#} wind. If one tree could survive here, {#blank#}8{#/blank#} could millions of trees, they thought.

    After decades of hard work, three generations of the foresters have restored almost 80% of the original Saihanba forest. Recently, they were awarded the {#blank#}9{#/blank#}（high）environmental honor from the United Nations for their great {#blank#}10{#/blank#}（contribute）to creating a greener world.

    Happiness can {#blank#}1{#/blank#}(describe) as a positive mood and a pleasant state of mind. There are many factors contributing to happiness.

A person {#blank#}2{#/blank#} an obviously ideal situation is not necessarily happy. The ideal situation may have little to do with his actual feelings.

A good education and income are usually considered necessary for happiness. Though both may contribute, {#blank#}3{#/blank#} are only chief factors if the person is {#blank#}4{#/blank#}(serious) undereducated or actually suffering from lack of physical needs.

    The rich {#blank#}5{#/blank#}(be) not likely to be happier than the middle-income group or even those with very low incomes. People with college educations are somewhat happier than those who did not graduate from high school, and it is believed that this is mainly {#blank#}6{#/blank#} they have more opportunity to control their {#blank#}7{#/blank#}(life). Yet people with a high income and a college education may be {#blank#}8{#/blank#}(little) happy than those with the same income and no college education.

    Poor health does not rule out happiness except for the severely {#blank#}9{#/blank#}(disable) or those in pain. Learning {#blank#}10{#/blank#}(cope) with a health problem can contribute to happiness.
