    At Wushan we made a {#blank#}3{#/blank#} up the Daning River to see some of the smaller gorges.

    The Chinese flag was {#blank#}4{#/blank#} in the wind. On a {#blank#}5{#/blank#} mountain was a sign in20-foot {#blank#}6{#/blank#}.

    The director of a {#blank#}7{#/blank#} tourist office, Meng Fanying, said the monster, which seemed black in colour, was ten metres from the edge of the lake during the most recent {#blank#}8{#/blank#}.

    They also think that there might be {#blank#}9{#/blank#} creatures in other lakes around the world. Scientists, however, are {#blank#}10{#/blank#}.

    In our daily life, we often meet with difficulties. Some people do nothing but wait, while others try hard to conquer{#blank#}1{#/blank#}. Personally, we should face with difficulties positively and make every effort to overcome them.

    My memory drew me back to five years ago when I was {#blank#}2{#/blank#} middle school student. At that time, I had great trouble studying English. First of all, I felt it hard to memorize English {#blank#}3{#/blank#} (word). Besides I didn't dare to say anything in class when I{#blank#}4{#/blank#} (ask) questions. What annoyed me most was that I failed exams{#blank#}5{#/blank#} (constant). I was about to give up{#blank#}6{#/blank#} my English teacher found my problems. He encouraged me and gave me some good advice.So {#blank#}7{#/blank#} (inspire) by him, I decided to settle my problems. {#blank#}8{#/blank#} (follow) his advice, I made progress gradually. I owe my achievement{#blank#}9{#/blank#}the teacher whose encouragement was of great {#blank#}10{#/blank#} (important).

    It is not a secret {#blank#}1{#/blank#} trees are vital to our life. They provide us with food, wood and most {#blank#}2{#/blank#} (important), oxygen. Now there is one more thing we can add to this list—blocking out harmful bacteria from water.

    The discovery {#blank#}3{#/blank#} (make) by a team {#blank#}4{#/blank#} (consist) of scientists from the Massachusetts Institute of Technology (MIT) and high school students {#blank#}5{#/blank#} were seeking a natural water filter(过滤)—one that would help communities in developing countries that do not have {#blank#}6{#/blank#} (accessible) to modern water filter systems.

    The {#blank#}7{#/blank#} (research), led by Professor Rohit Karnik, decided to turn{#blank#}8{#/blank#} trees for help, because they could allow liquid to flow through, while blocking out air bubbles.

    They began by cutting 1.5-inch-wide sections of tree bark from the branches of a white pine tree. The people related then tested the wood's filtering ability by pouring water containing red dye particles of different sizes through. To their {#blank#}9{#/blank#} (amaze), they found that it was effective in trapping all the particles. Greatly {#blank#}10{#/blank#} (encourage), the team conducted another experiment, this time with water that contained bacteria. Sure enough, the sapwood held back 99% of the bacteria, allowing only 1% to flow through.

    Colorful lanterns are lighting up China's night sky, as activities begin across the country to celebrate Lantern Festival today.

    {#blank#}1{#/blank#} (date) back to the Western Han Dynasty (206 BC-AD 25), the Lantern Festival is held on the 15th day of the first lunar month {#blank#}2{#/blank#}(mark) the first full moon of the lunar new year.

    You Guoqing, {#blank#}3{#/blank#} folk custom expert in Tianjin, said the Lantern Festival was about going out for a colorful celebration rather than a family get-together. {#blank#}4{#/blank#}watching lanterns, {#blank#}5{#/blank#} is also a day to appreciate the full moon, solve lantern riddles, watch art {#blank#}6{#/blank#}(performance) and eat tang yuan.

    The festival was once also a time for romantic encounters. In feudal times, young women were not allowed to go out {#blank#}7{#/blank#}(free), but Lantern Festival was an exception, {#blank#}8{#/blank#} young men and women could meet up.

    Some aspects of the festival, such as its romantic atmosphere, {#blank#}9{#/blank#} (fade), but people {#blank#}10{#/blank#} see the Lantern Festival as a day to rejoice and a chance to wish for happiness.

    In recent years,sandstorms {#blank#}1{#/blank#}(occur) in China frequently,especially in northwestern areas, {#blank#}2{#/blank#}severe influence has caused wide concern in China.

There're several reasons for this.First of all,people are cutting down trees without planting more, {#blank#}3{#/blank#}(make) some land become deserts.Another reason is {#blank#}4{#/blank#}it rains less due to the environment pollution.

    To {#blank#}5{#/blank#}(efficient) prevent sandstorms,first,we should plant more trees and grass which can keep the soil {#blank#}6{#/blank#} being washed away.Second,more green fences should {#blank#}7{#/blank#}(build) along the desert, {#blank#}8{#/blank#}it helps to control the process of the desertification.

    Let's take action to do what we can {#blank#}9{#/blank#}(prevent) sandstorms from today.Soon the golden days we have been looking forward to {#blank#}10{#/blank#}(come).

    I first met Steve Jobs years ago at a yard pool party. I was {#blank#}1{#/blank#} excited and embarrassed by the chance to meet him in person that I could hardly whisper my name when we {#blank#}2{#/blank#}(introduce). I watched as he swam in the pool with his son, like a regular guy, a good dad {#blank#}3{#/blank#}(have) fun with his kids.

    The second time I met him was when our children started going to school together. He was sitting in the classroom while {#blank#}4{#/blank#}rest of us were pretending that having Steve Jobs in the room was {#blank#}5{#/blank#} (total) normal. It was one Halloween when I realized he actually knew my name, {#blank#}6{#/blank#} made me a little surprised. {#blank#}7{#/blank#}(dress) like a monster, he was decorating a scary house with his wife. As I walked by with my son, Steve smiled and said, “Hi, Lisen”, My son thought I was the {#blank#}8{#/blank#}(cool)mom in town when he realized Steve Jobs knew me.

    {#blank#}9{#/blank#} then on, when I saw him holding his meetings in our neighborhood, I didn't hesitate to smile and say hi. Steve always {#blank#}10{#/blank#} (return) the greetings, proving that while he may have been a genius, he was also a good neighbor.
