Beijing was once a city of bikes, known as the Bicycle Kingdom{#blank#}1{#/blank#} cars were reserved for official business and the politically powerful. However, decades of economic {#blank#}2{#/blank#} (grow) led to a huge flowing of cars in the city. Owning one became not just a marker of reaching the middle class but also a requirement for marriage. As the economy developed, autos pushed bikes off the roads{#blank#}3{#/blank#}(create) heavy pollution and miserable traffic.

    {#blank#}4{#/blank#} (fortunate), now Beijing may be returning to its roots. Thanks to about 20 technology companies, brightly colored shared bikes {#blank#}5{#/blank#} (flood) into Beijing in the last two years. Many local residents welcome the shared bikes {#blank#}6{#/blank#}the flexibility and freedom they offer. They pick up the bikes and then ride and drop{#blank#}7{#/blank#} off anywhere they like, locking the back wheel, with no need to find a fixed place.

    Analyses in China say it is three factors that contribute to bikes {#blank#}8{#/blank#} (increase) rapidly: a lot of cash looking for a home, a good idea and government support. “As the city's population grew, traffic jams got{#blank#}9{#/blank#}(bad).” Cai, the Ofo spokeswoman, said, “Shared bikes could solve the 'last mile' problem in{#blank#}10{#/blank#} environmentally friendly way.”

    The Laba Festival which is celebrated on the eighth day of the {#blank#}1{#/blank#}(twelve) month of the lunar Chinese calendar is a traditional Chinese holiday. “La” is the name of the month and “ba” has the same {#blank#}2{#/blank#}(pronounce) as that of 8 in Chinese.

    There are several {#blank#}3{#/blank#}(story) about the origin of this festival and it's difficult for us to tell which one is true. But today {#blank#}4{#/blank#}we do know is that this festival began as a way to honour ancestors. It was also {#blank#}5{#/blank#} time for the ancient Chinese to pray for a good harvest.

    The majority of Chinese have long followed the tradition of {#blank#}6{#/blank#}(eat) Laba porridge during the Laba Festival. {#blank#}7{#/blank#} general, the porridge contains eight ingredients, including some beans and rice. {#blank#}8{#/blank#}(traditional), Laba porridge is the most important part of the festival. Also, it is important that family members eat the porridge together.

    {#blank#}9{#/blank#} custom is soaking Laba garlic(蒜），{#blank#}10{#/blank#} is the best seasoning for the dumpling feast at the Spring Festival.

    Once a group of 50 people was attending a seminar. Halfway through his talk, the speaker stopped and decided {#blank#}1{#/blank#} (create) a group activity. He went around the hall and gave each person a balloon. Each one was asked to write his or her name on the balloon {#blank#}2{#/blank#} (use) a marker pen. Then all the balloons were {#blank#}3{#/blank#} (collect) and put in another room.

    The speaker then led the group to the room full of balloons and asked them to find the balloon {#blank#}4{#/blank#} had their name written on, within five minutes. Everyone was {#blank#}5{#/blank#} (hurried) searching for their name, bumping into each other, pushing each other around. It was chaos. At the end of the five minutes no one could find {#blank#}6{#/blank#} (them) own balloon.

    Now each person was asked to randomly collect {#blank#}7{#/blank#} balloon and give it to the person whose name was written on it. Within two minutes everyone {#blank#}8{#/blank#} (have) their own balloon. When everyone quieted down, the speaker began to talk, saying that this is exactly what was happening in our {#blank#}9{#/blank#} (life)．Everyone is hurriedly looking for happiness, and not knowing where it is.

    Our happiness sometimes lies in the happiness of other people. Give them happiness {#blank#}10{#/blank#} you will get your own happiness.

    On May 9, James Givens was sitting in the car when he{#blank#}1{#/blank#}(hear) what sounded like a knock. He turned around only{#blank#}2{#/blank#}(find) a goose pecking (啄) at the car door. This was highly unusual given that the birds normally preferred to observe humans from a{#blank#}3{#/blank#}(distant).

But on this day, the goose appeared to be determined to get his attention and didn't stop pecking{#blank#}4{#/blank#}Givens opened the car door and stepped out .Though the bird then began to walk away,{#blank#}5{#/blank#}kept turning around to make sure he was following. When they finally stopped, Givens realized{#blank#}6{#/blank#}the mother goose did so— she needed help to free her baby goose that had got{#blank#}7{#/blank#}(trap) in some balloon string.

    Worried that the mother goose would attack him if he got close{#blank#}8{#/blank#}the baby, Givens called the local SPCA chapter. Unfortunately, they were{#blank#}9{#/blank#}(able) to help right away. Concerned that the baby goose would not survive the delay, Givens decided to take on the task himself.

    The mother goose watched{#blank#}10{#/blank#}(patient) as Givens saved the little bird. As soon as the little goose was free, it ran to its mom. Givens said this was the most unforgettable incident in his life!

    Modern-day robots are programmed to handle tasks that are normally carried out by humans. They are faster and{#blank#}1{#/blank#}(accurate) than human workers and never ask for a pay rise or take breaks!

    Robots are also able to work{#blank#}2{#/blank#}dangerous situations.

    Researchers at the University of Arkansas in the United States say that the mobile robots which have been created already are ideal for the job of hospital attendants. These mobile robots store a{#blank#}3{#/blank#}(detail) map of the hospital in their memory. The robots' sensors can detect{#blank#}4{#/blank#}(object) and quickly get out of the way. Although these robots cannot go up and down know how{#blank#}5{#/blank#}(press) a button of an elevator.

    Researchers at a Massachusetts' university are creating the first robot {#blank#}6{#/blank#}can constantly change its shape according to the task it has to do. These are called polymorphic robots. "Polymorphic" means{#blank#}7{#/blank#}ability to take different forms. A 3D printer{#blank#}8{#/blank#}(place) inside the robot to create the desired shape. The entire process of changing forms in this manner is called the rapid printing technology which is{#blank#}9{#/blank#}(fair) common in the car industry to produce complex 3D structures quickly. Once the robot has performed{#blank#}10{#/blank#}(it) task, it can be melted down and recycled into another useful part by the 3D printer.
