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.”

    Last Monday, my father would be on a{#blank#}1{#/blank#}(busy) trip for five days. Having gotten my promise of being great at home and taking care of my mother, he rest assured and put his luggage into the trunk of his car.{#blank#}2{#/blank#}(see) my father's driving away, my mother and I waved our hands and said goodbye to him. For a moment, I began to miss my father,{#blank#}3{#/blank#}(wish) that he would be safe and well the next days. I thought everything would go well, as this was not the first time that my father{#blank#}4{#/blank#}(be) away for several days. Yet, —{#blank#}5{#/blank#}(fortunate), my mother caught a cold the next morning. Looking at her pale face, I {#blank#}6{#/blank#}(experience) high levels of anxiety. However, I told myself that I had to calm down and look after my mum, {#blank#}7{#/blank#}I promised to my dad. The moment I got my mum to sleep, I put cold towel on her forehead, found pills in the medicine box, and made some noodles for her. Luckily, she woke up and felt {#blank#}8{#/blank#}(good) after taking the pills and the noodles. {#blank#}9{#/blank#}her fever was gone relieved and satisfied me a lot. In the next four days, I was taking her body temperature twice a day, ensuring that she was completely well. To our delight, my dad went back home safe and sound on Saturday. On hearing {#blank#}10{#/blank#}I had done to my mum, he as well as my mum beamed at me and gave me a big thumb. Hearing their praises and seeing bright smiles on their faces, I really felt overjoyed and thrilled. Taking care of my parents was, indeed and definitely, my mission and obligation。

    Many people wonder if there is any {#blank#}1{#/blank#} (connect) between our senses and our health. Scientists observe that making the most of our senses when we are young can keep us healthy later on in life.

    Why do we feel {#blank#}2{#/blank#} (anxiety) or tired? One study shows that {#blank#}3{#/blank#} (approximate) 90% of our time is spent watching television or using computers. It is added that while our sense of sight is used too much, our {#blank#}4{#/blank#} (sense) of touch and smell have been ignored.

    People often ask {#blank#}5{#/blank#} or not we should develop all our senses. The answer is yes. Experts suggest that we do the {#blank#}6{#/blank#} (follow) things more often. While having dinner, listen to some {#blank#}7{#/blank#} (enjoy) music rather than watch television. While relaxing at home, have some flowers next to you {#blank#}8{#/blank#} smell nice. Before going to bed, turn the lights {#blank#}9{#/blank#}. While sleeping, wear a nightshirt that is pleasant to touch—it {#blank#}10{#/blank#} (make) us sleep well.

    The way you walk may be determined by your daily schedule, and it may also reflect your personality. The {#blank#}1{#/blank#} (choose) you make can tell something about your inner thoughts. At least, that's {#blank#}2{#/blank#} science has proved. Lately, researchers {#blank#}3{#/blank#} (observe) the way that people walk and how it relates to their personalities. Available online via Sage Journals, the study examines both the walking styles and personalities of 15, 000 adults aged from 25 to 50. According to the study, when {#blank#}4{#/blank#} (face) with the new challenges, fast walkers are more likely to be active while quiet people tend to walk more slowly. Meanwhile, the study has also found {#blank#}5{#/blank#} (power) evidence that walking speed in adulthood reflects the individual's personality. However, speeding up your walking pace can't {#blank#}6{#/blank#} (instant) make you the life of the party, {#blank#}7{#/blank#} means that you needn't change your personality. Actually, there are {#blank#}8{#/blank#} (hide) strengths of being a quiet person as well as an active one. Make the most of your strengths, {#blank#}9{#/blank#} you can be successful regardless of which type you fall into and {#blank#}10{#/blank#} fast or slowly you walk.
