Two little children were sitting by the fire one cold winter's night. Suddenly, they heard a knock at the door. “Who can it be?” they wondered. One ran{#blank#}1{#/blank#} (curious) to open it. There, outside in the cold and the darkness, stood a child {#blank#}2{#/blank#} no shoes on his feet and dressed in old thin garments. He was trembling with cold, {#blank#}3{#/blank#} he asked to come in and warm himself.

    “Yes, come,” cried both the children. They drew the little stranger to their warm seat, {#blank#}4{#/blank#} (share) their supper with him, and gave him their bed, and they slept on a hard bench.

    On the night, they{#blank#}5{#/blank#} (awake) by sweet music,{#blank#}6{#/blank#} was played by a band of children in shining garments. Suddenly the stranger child stood in front of {#blank#}7{#/blank#}: no longer cold and ragged, but dressed in silvery light. He said, “I am the Christ Child, {#blank#}8{#/blank#} (wander) through the world to bring peace and {#blank#}9{#/blank#}(happy) to good children as you. As you have helped me so much, this tree will give rich fruit to you every year.”

    When he was saying that, he broke {#blank#}10{#/blank#} branch from the tree that grew near the door, planted it in the ground and disappeared. But the branch grew into a great tree, and every year it bore wonderful golden fruit for the kind children.

    As kids reach adolescence, they often face increasing workloads and responsibilities but school still starts early. As a result, it {#blank#}1{#/blank#} (report) that 80 to 90 percent of teens don't get enough sleep. This sleep {#blank#}2{#/blank#} (lose) causes kids to suffer mentally and physically. But too much sleep also has its problems. According to Andrew Fuligni, a sleep doctor in a famous hospital,{#blank#}3{#/blank#} studies the mental health of adolescents, sleeping less than eight hours {#blank#}4{#/blank#}more than ten can make teenagers feel worse the next day.

    {#blank#}5{#/blank#} (help) teens get enough sleep, some schools have already made school start later. They have found that the later times let kids sleep more. They also have seen{#blank#}6{#/blank#} (high) test scores and better graduation rates. However, this isn't enough. Meanwhile, teenagers have to help {#blank#}7{#/blank#} (they). Fuligni suggests teens sleep{#blank#}8{#/blank#}10 hours each night for a week or two. This will help them figure out how much sleep they need. However, sleeping more on weekends {#blank#}9{#/blank#}(be) not a good idea to compensate for missing sleep during the week. Fuligni warns that getting different {#blank#}10{#/blank#}(amount)of sleep each night can be bad for mental health.

    What is standard English? Is it spoken in Britain, the US, Canada, Australia, India and New Zealand? Believe it or not, there is no such thing as standard English. Many people believe the English spoken on TV {#blank#}1{#/blank#} the radio is standard English. This is because in the early days of radio, those who {#blank#}2{#/blank#}(report) the news were expected to speak excellent English. However, on TV and the radio you will hear differences in the way people speak.

    When people use words and {#blank#}3{#/blank#}(expression) different from the "standard language", it is {#blank#}4{#/blank#}(call) a dialect. American English{#blank#}5{#/blank#}(have) many dialects, especially the Midwestern, southern, African American and Spanish dialects. Even in some parts{#blank#}6{#/blank#} the USA, two people from neighboring towns speak a little {#blank#}7{#/blank#}(different). American English has so many dialects because people have come from all over the world. Geography also plays a part in {#blank#}8{#/blank#} (make) dialects. Some people {#blank#}9{#/blank#}live in the mountains of the eastern USA speak with an older kind of English dialect. When Americans moved from one place to another, they took their dialects with {#blank#}10{#/blank#}(they).

    On Aug 13，four Chinese irrigation sites won global {#blank#}1{#/blank#} (recognize)and were added to the 2018 list of Heritage Irrigation Structures， among {#blank#}2{#/blank#} Dujiangyan is the oldest and only surviving damless irrigation system in the world.

    Built over 2，000 years ago in {#blank#}3{#/blank#} is now Sichuan Province in Southwest China， this amazing engineering achievement is still playing a crucial role in irrigating farms and providing water resources for more than 50 cities in the province.

    In ancient times，the region in which Dujiangyan now stands {#blank#}4{#/blank#} (threaten)by frequent flooding from the Minjiang River. Li Bing，a local official of Sichuan Province at that time，together with his son，decided to construct an irrigation system on the Minjiang River {#blank#}5{#/blank#} (prevent)flooding. After many studies，they found the {#blank#}6{#/blank#} (simple)solution was to build a dam，but this would have ruined the Minjiang River. So instead Li designed a series of {#blank#}7{#/blank#} (channel)built at different levels along Mount Yulei that would take away the floodwater while leaving the river flowing {#blank#}8{#/blank#} (natural).Better still， the extra water could be directed to the dry Chengdu Plain，{#blank#}9{#/blank#} (make)it suitable for farming.

    Ever since the great Dujiangyan Irrigation System was completed， the Chengdu Plain has been free {#blank#}10{#/blank#} flooding and the people there have been living peacefully.

One day, the man offered me some crack cocaine, a more {#blank#}4{#/blank#}（power）addictive. When I went back to the man for more crack cocaine, he asked me for a lot of money. I was in terrible pain when I couldn't afford to buy any drugs. {#blank#}5{#/blank#} (get) money, I broke into{#blank#}6{#/blank#} house and stole something to sell for money. The more drugs I took, the more addicted I became. So I had to steal something every day to pay for the drugs. One day, I{#blank#}7{#/blank#}（catch）stealing and sent to the police station. The next day, a doctor came to see me and told me that I could die {#blank#}8{#/blank#} I couldn't stop taking drugs. I took his advice and stopped {#blank#}9{#/blank#}(immediate). Now I work in a center for drug addicts, {#blank#}10{#/blank#} (help) others to stop taking drugs.
