If you are a little afraid when you walk alone at night, you can phone your family to make sure they know you are s{#blank#}1{#/blank#} But making calls may make you the target (目标) for bad people.

    Now there is an app and i{#blank#}2{#/blank#}lets your family know your journey. And it will call for help when it feels you're i{#blank#}3{#/blank#}danger.

    The app is c{#blank#}4{#/blank#} Companion(同伴). Before you start your journey, you input your starting place and your finishing place. Then you s{#blank#}5{#/blank#} them to your companion. The companion can be anyone in your phone book, and they don't n{#blank#}6{#/blank#}to have the app.

    The app will tell your companion w{#blank#}7{#/blank#}you are at any time. And it will show a button(按钮) on your phone screen every few m{#blank#}8{#/blank#}asking “Are you OK?” If you don't press the button in 15 seconds(秒), your companion will get an alarm(报警). And the app will be ready to call the police for h{#blank#}9{#/blank#}.

With the app, you will never be w{#blank#}10{#/blank#}about going home alone.

    Around the world people have different traditions and {#blank#}1{#/blank#} (风俗) when it comes to dining. It's important to respect(尊重) these customs.

    Not all countries {#blank#}2{#/blank#} (期望) you to leave a tip after a meal. In fact, in Japan it is seen as {#blank#}3{#/blank#} (不礼貌的). Employees in some Chinese restaurants are even not {#blank#}4{#/blank#} (允许) to get tips. However, other countries {#blank#}5{#/blank#} (像) France and Italy usually have a service charge.

    In Japan and China, you should {#blank#}6{#/blank#} (从不) stick chopsticks into rice. In India, utensils aren't always {#blank#}7{#/blank#} (提供). You should eat a meal with your {#blank#}8{#/blank#} (右边的) hand, as the left is considered dirty. Thai restaurants will often provide customers with a fork and spoon- they use the fork to push food onto the spoon rather than (而不是) eating {#blank#}9{#/blank#} (直接地) from it.

    People in many Western countries will never make a noise {#blank#}10{#/blank#} (在……期间) a meal, but in some places making a noise is a sign of appreciation(欣赏). In Japan, slurping soup and noodles straight from the bowl shows that you are enjoying your meal.
