The earth was just {#blank#}1{#/blank#} cloud of dust after the “Big Bang”. The earth exploded {#blank#}2{#/blank#}(loud) with fire and rock. They were in time to produce carbon, nitrogen, water vapour and other gases, which were {#blank#}3{#/blank#}(make) the earth's atmosphere. As the earth cooled down, water began to appear on its surface. It allowed the earth to dissolve {#blank#}4{#/blank#}(harm) gases. Then life began to develop.

    Small plants multiplied and filled the oceans and seas with oxygen. This encouraged the {#blank#}5{#/blank#}(develop) of early shellfish and fish. Land animals such as insects, reptiles and dinosaurs {#blank#}6{#/blank#}(appear) after green plants came into being. Small clever animals spread all {#blank#}7{#/blank#} the earth. They are putting too much carbon dioxide into the atmosphere, {#blank#}8{#/blank#} prevents heat from escaping from the earth into space. {#blank#}9{#/blank#} life will continue on the earth for millions of years to come will depend on whether this problem can {#blank#}10{#/blank#}(solve).

    I enjoy{#blank#}1{#/blank#} (climb) mountains whenever I can find the time to do so. Tom and Mike are my best friends. Both of {#blank#}2{#/blank#} also like sports. Two years ago, the three of us {#blank#}3{#/blank#} (go) up to Mt. Lushan. Instead of taking a bus, which would be {#blank#}4{#/blank#} (comfortable), we preferred to climb. We started {#blank#}5{#/blank#} the foot of the mountain early in the morning, chatting all the way. After about one and a half hours' climbing, we saw two mountain {#blank#}6{#/blank#} (path) before us. We could not decide {#blank#}7{#/blank#} to choose. In the end, we took the path on the right, thinking that might be a short cut. But we were wrong. {#blank#}8{#/blank#} (lose) in the mountain, we could not find our way out. We had to use our hands and feet to make a way. We began to cry for help {#blank#}9{#/blank#} nobody answered. It was not until darkness {#blank#}10{#/blank#} (fall) that we found a right path leading up to a paved road.

    The Dragon Boat Festival has been marked by {#blank#}1{#/blank#} (eat) zongzi and racing dragon boats for thousands of years. It falls on {#blank#}2{#/blank#} fifth day of the fifth month according to the Chinese lunar calendar in honor of Qu yuan, {#blank#}3{#/blank#} is said to have committed suicide by drowning himself.

    Qu was minister of the state of Chu {#blank#}4{#/blank#} (lie) in the present-day Hunan and Hebei provinces during the Warring States period. He was upright, loyal and {#blank#}5{#/blank#} (high) respected. However, he was fired from office due to his suggestion to fight against Qin in cooperation with other states. During his stay in other states, he wrote a number of {#blank#}6{#/blank#} (poem) to express his strong love for his country. When Chu {#blank#}7{#/blank#} (defeat) by Qin. He realized what he could do about it was nothing. Qu jumped into Miluo River on the fifth day of the fifth month.

    After the {#blank#}8{#/blank#} (die) of Qu Yuan, people of Chu went to Miluo River to mourn over the great poet they loved so much. People threw eggs and rice wrapped in leaves {#blank#}9{#/blank#} the river to feed the fish to keep them away from Qu Yuan. Now the Dragon Boat Festival has become {#blank#}10{#/blank#}（tradition） festival for the Chinese people.

    To celebrate the Lantern Festival the Palace Museum organized its first light show in the Forbidden City.

    The complex, home to Chinese emperors for five {#blank#}1{#/blank#}(century), was opened at night for the first time in 94 years. It was lit up with giant red lanterns and projections of ancient paintings. Masterpieces such as Along the River During the Qingming Festival were projected on the roofs, giving visitors a feeling like walking {#blank#}2{#/blank#} time. The design team smartly combined high technology{#blank#}3{#/blank#}(light) with the principles of cultural relic preservation.

    Only 3, 000 people {#blank#}4{#/blank#}(allow) in on that day: 500 people who booked their tickets online, and 2, 500{#blank#}5{#/blank#}(invite) guests including model workers, officers, soldiers, and ambassadors.

    With{#blank#}6{#/blank#} series of well-planned and tourist-friendly cultural activities, the Palace Museum is now on a campaign to make traditional Chinese culture more {#blank#}7{#/blank#}(access) to the general public. It has set an example to other museums in our country, most of {#blank#}8{#/blank#} seem to be still living in days gone by. Hopefully, the handsome turnover will be used{#blank#}9{#/blank#}(appropriate) to better protect the Forbidden City and improve {#blank#}10{#/blank#}(it)international image of being part of the world's cultural heritage.
