That Beijing, together with Zhangjiakou, succeeded in getting the chance to host the 2022 Winter Olympic Games, speeds up the development of Zhangjiakou City. Word came {#blank#}1{#/blank#}the Beijing-Zhangjiakou high-speed railway, {#blank#}2{#/blank#}(locate) in North China, is currently under construction, and {#blank#}3{#/blank#}(expect) to be completed by 2020 in preparation for the cities to host the 2022 Winter Olympics. Starting from Beijing North Railway Station, heading west through the Great Wall three times in the capital's territory, the project is a big challenge, {#blank#}4{#/blank#} designers say the explosions needed to dig the tunnels will not have an impact on the structure. The line has a {#blank#}5{#/blank#}(long) of 174 km as a double tracked passenger dedicated line, with ten stations situated along its route. Having a {#blank#}6{#/blank#}(totally) investment of 31.17 billion yuan ($5 billion), the trip between the two cities will only take 40 minutes, with the train {#blank#}7{#/blank#}(travel) at an average of 250 km/h. According to the plan, the high-speed railway will build two branch lines—one is to Yanqing Station and the other {#blank#}8{#/blank#} Taizicheng of Chongli, {#blank#}9{#/blank#} the Olympic village lies. The full railway, which includes 70-kilometer section through Beijing, will be completed in four and {#blank#}10{#/blank#} half years.

    Why men wolf down their meals {#blank#}1{#/blank#} women take their time? Many a woman has watched in disbelief as their partners eat their food minutes after sitting down to dinner. Now Korean researchers have discovered why: men and women {#blank#}2{#/blank#} (actual) chew differently. Women chew each individual mouthful more times — taking longer to finish {#blank#}3{#/blank#} (eat) their meal.

    The researchers hired 24 males and 24 females in South Korea. They recorded the size of people's bites, total chewing time per mouthful of food, total number of chews and how long {#blank#}4{#/blank#}   took the person to eat the entire meal. Men typically take {#blank#}5{#/blank#}   (large) bites with more “chewing power”, {#blank#}6{#/blank#} means they consume their meal more quickly than women.

    Though women were watched {#blank#}7{#/blank#} (have) the same chewing pace as men, they chewed each mouthful more times, slowing down the total time it took them to eat their meal.

    The study {#blank#}8{#/blank#} (publish) in the January issue of the Physiology and Behaviour Journal. But it flies in the face of an earlier result studied {#blank#}9{#/blank#} researchers at Nippon Dental University in Tokyo, Japan, which found no {#blank#}10{#/blank#} (different) in how the sexes chewed gum.

    My wife is addicted to shopping on the Internet. {#blank#}1{#/blank#} seems that she can't control herself well, just clicking constantly with the mouse. Let me tell you what happened last night. It was the fourth time she {#blank#}2{#/blank#}(shop) online for hours. I had already reminded her {#blank#}3{#/blank#}(think) twice before buying anything, but my wife ignored {#blank#}4{#/blank#}I said and replied confidently, “With the New Year {#blank#}5{#/blank#}(approach)”, preparation is necessary. Besides, I haven't bought things on the Internet for a whole week.” Hearing her words, I was really speechless. In most cases, the things she bought aren't good value for money. Maybe she just enjoys {#blank#}6{#/blank#}process of buying online.

    Nowadays, {#blank#}7{#/blank#} the development of technology, online shopping is becoming more and more convenient. Those {#blank#}8{#/blank#}stay at home can buy whatever they want. In the meanwhile, it causes a series of problems. One of them {#blank#}9{#/blank#}(be) more spending than before, because people are {#blank#}10{#/blank#}(easy) attracted by the discount. So how to keep a good state of mind in front of temptation（诱惑）is an important lesson many people need to learn.

    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。
