What is the most popular communication tool today? {#blank#}1{#/blank#}your answer is QQ or MSN, I must say you're a bit old fashioned. Today, a new form of communication “Wechat”, which {#blank#}2{#/blank#} (own) a Chinese name Weixin, is becoming the most influential text and voicing tool all over the world.

What advantages does Wechat have? First, Wechat is {#blank#}3{#/blank#}relatively cheap way of communication; that is to say, it uses network traffic instead of telephone fare. Next, we can know {#blank#}4{#/blank#} is going on at any time. And we can have {#blank#}5{#/blank#} (easily) access to information available than other messaging tools.

What roles does it play in our daily life? According to the latest report, the number of the {#blank#}6{#/blank#} (register) users on Wechat platform has topped 200 million and it has expanded its business to overseas market. Can you imagine that a mobile phone ‘app' works so {#blank#}7{#/blank#} (power) that it reaches 200 million users within 8 months? Wechat itself has become the most popular mobile chat application in the world. A large number of people have become “Wechataholic”, which means they keep staring at the mobile phone all the time and can't live {#blank#}8{#/blank#} it.

However, while enjoying its great {#blank#}9{#/blank#} (convenient), people should not ignore the danger of  {#blank#}10{#/blank#} (cheat), for information on Wechat is publicly known.

    There has been a recent trend in the food service industry toward lower fat content and less salt．This trend，which was started by the medical community（医学界）{#blank#}1{#/blank#} a method of fighting heart disease，has had some unintended side{#blank#}2{#/blank#}（effect） such as overweight and heart disease---the very thing the medical community was trying to fight．

    Fat and salt are very important parts of a diet．They are required{#blank#}3{#/blank#}（process） the food that we eat，to recover from injury and for several other bodily functions．When fat and salt {#blank#}4{#/blank#}（remove） from food，the food tastes as if it is missing something．As{#blank#}5{#/blank#}result，people will eat more food to try to make up for that something missing．Even {#blank#}6{#/blank#}（bad），the amount of fast food that people eat goes up．Fast food{#blank#}7{#/blank#}（be） full of fat and salt； by {#blank#}8{#/blank#} （ eat） more fast food people will get more salt and fat than they need in their diet．

    Having enough fat and salt in your meals will reduce the urge to snack（吃点心） between meals and will improve the taste of your food．However，be {#blank#}9{#/blank#} （care） not to go to extremes．Like anything，it is possible to have too much of both，{#blank#}10{#/blank#} is not good for the health．

    Are people happier in nature with blue skies overhead and fresh green grass underfoot? Could noisy streets, {#blank#}1{#/blank#} (crowd) with cars and people, make us unhappy? The World Health Organization estimates that 54 percent of the world's population lived in urban areas in 2014. The WHO adds that that amount {#blank#}2{#/blank#} (increase) to 66 percent by 2050.

    People often move to cities for{#blank#}3{#/blank#} (good) jobs and more cultural activities. But are they putting {#blank#}4{#/blank#}(they) at risk?

    Experts say that natural environments or green spaces do a lot of good for our mental health.

    Many studies have shown that nature can calm us and make us feel happy. Nature, experts say, can also help us learn better. And {#blank#}5{#/blank#} (experience) nature helps people recover from the mental tiredness that {#blank#}6{#/blank#}(come) from day-to-day work.

Mental health experts say some research suggests that city living might hurt our mental health, {#blank#}7{#/blank#} they cannot say exactly why. “What are the specific{#blank#}8{#/blank#} (aspect) of the urban environment {#blank#}9{#/blank#}causes some people to develop mental health issues?” asked AndraMechelli, a doctor at Kings College, London.

    Researchers have found that being outdoors, seeing trees, hearing birdsong, seeing the sky, and being {#blank#}10{#/blank#}touch with nature are associated with higher levels of mental well-being.

    If we are honest with ourselves, most of us have dreamed of {#blank#}1{#/blank#} (become) famous. Most musicians form a band because {#blank#}2{#/blank#} the same interest in writing and playing music. They may play anywhere {#blank#}3{#/blank#} (earn) some extra money as {#blank#}4{#/blank#} as fulfill their dreams. However, the Monkees {#blank#}5{#/blank#} started differently, began as a TV show with the musicians {#blank#}6{#/blank#} (play) jokes and music in the programme. Only after a year or so did they become {#blank#}7{#/blank#} (serious) and they produced their own records {#blank#}8{#/blank#} later became even more popular than the Beatles in the USA. The band once {#blank#}9{#/blank#} (break) up but reunited later. In memory of their time as a real band, they produced {#blank#}10{#/blank#} new record in 1996.
