    Lucy likes July{#blank#}4{#/blank#}she likes the summer holiday(暑假). In July, her parents take{#blank#}5{#/blank#}to travel(旅行). It's really great.

    Wang Ping is a cleaner. He has {#blank#}1{#/blank#} in a park for 5 years. He is also a good father. Nothing can make him {#blank#}2{#/blank#} than playing with his little daughter in his free time.

    Last Tuesday afternoon, while he was {#blank#}3{#/blank#} the park, suddenly, he heard a woman crying for help. He ran up {#blank#}4{#/blank#} to see what happened. The woman's 15-month-old baby girl choked(窒息) on a small piece of fruit and her face {#blank#}5{#/blank#} purple. The baby was too young to save herself, and the mother was so nervous that she didn't know how to save her daughter properly. Luckily, Wang Ping knew what to do. He took the baby in his {#blank#}6{#/blank#} without thinking twice. With the mother's help, Wang Ping held the baby upside down and gave her a few pats (轻拍) on the back. After a short while, he succeeded in getting the piece out of her mouth and the baby began to cry. Her mom was so thankful because her daughter was {#blank#}7{#/blank#}.

    Wang Ping tried his best and saved the {#blank#}8{#/blank#} life. In his mind, helping others is just helping. {#blank#}9{#/blank#}. He hoped more people could {#blank#}10{#/blank#} to help the people in need if possible.

    We do not know when people invented wheels. But once it was invented, knowledge of the wheel{#blank#}1{#/blank#}quickly across the world. It is easy to move things with wheels. The first example of wheels dated from about 3. 500 to 3. 000 BC. The cart or wagon was the first vehicle which had wheels. At that time, they were pulled by humans or animals. Today, there are still carts drawn by animals in many countries. These carts are mainly used to move things or{#blank#}2{#/blank#}people. Around 2, 000 BC, the chariot(双轮敝篷马车)appeared. It moved even faster than the cart, so it soon became an important{#blank#}3{#/blank#}in the war and later was introduced to other ancient countries, such as Egypt, Persia, Greece and Rome.

    The invention of wheels is very important to the{#blank#}4{#/blank#}of new transportations. Without wheels, the invention of bicycles, motorcycles, cars, trains, and planes may not be possible.
