Tears come out of my eyes when I talk to my parents on the phone. {#blank#}1{#/blank#} This is what I want to know most. I have supper at 5 o'clock in the dining room. Now it is the busiest time for my parents. Dad works from seven o'clock in the morning to nine o'clock in the evening, so all the housework is left to my mum. {#blank#}2{#/blank#} Every day she gets up at 4 o'clock in the morning, and then works till dark.

    I promise her to study hard in the university because I am her hope. {#blank#}3{#/blank#} I just want her to promise me that she can take care of herself and my dad because they are just like the blood in my body.

    In my family, everyone is equal. We are very happy to have meals together. Mum says that the happiest time for Dad and her is to see my sister and me come back home. We play cards in the room, watch TV and do anything we like, with Dad and Mum preparing delicious food in the kitchen. {#blank#}4{#/blank#} I forget all the difficulties and unhappiness at that time. The only thing I would like to do is to enjoy the time with my parents.

    {#blank#}5{#/blank#} Love your parents as they love us. Give them a call, telling them you love them and miss them.

    When you wave to a friend, you are using body language. When you smile at someone, you mean to be friendly. When you put one finger in front of your mouth, you mean "be quiet". Yet, people in different countries may use different body languages.

    Once, an Englishman was in Italy. He could speak little Italian. One day while he was walking in the street, he felt hungry and went into a restaurant. When the waiter came, the Englishman opened his mouth, put his fingers into it and took them out again and moved his lips. In this way, he meant to say, "Bring me something to eat." But the waiter brought him a lot of things to drink, first tea, then coffee, then milk, but no food.

    The Englishman was sorry that he was not able to tell the waiter he was hungry. He was ready to leave the restaurant when another man came in. The man put his hands on his stomach, and this body language was good enough for the waiter. In a few minutes, the waiter brought him a large plate of bread and meat.

    Finally the Englishman had his meal in the same way.

    Need a reason to be happy? Then you will be happy to know that March 20th is the International Day of happiness.

    The united Nations set up the International Day of happiness in 2012 to remind us that happiness is a basic human goal and right.

    It was celebrated for the first time in 2013. On that day, we celebrated hundreds of "Happy Heroes" – those who did so much to bring happiness to others. They helped the homeless to live a comfortable life and the poor kids to go to school.

    The 2014 Day of Happiness actions asked people to share pictures of making them happy. People all over the world showed their favourite pictures on the Internet. "It's exciting to see so many people sharing photos of what makes them happy." Joe, a senior high school students from Canada said. The 2015 Day of happiness actions gave attention on relationships. Modern society is leaving more and more people felling lonely. On that day, thousands of people all around the world reached out to make new connections with others. They visited their neighbours, gave calls to the doctors they didn't know very well, drove the strangers to station for free…

    The theme of the 2019 Day of Happiness is "Happier Together". It encourages people worldwide to focus on what we have in common, rather than what divides us.

    Don't be too surprised if you see a car going down the road without a driver in Beijing these days. {#blank#}1{#/blank#}Last month, Baidu began to test its self-driving cars on open roads in Beijing.

    {#blank#}2{#/blank#}Since then, companies like Tesla, Uber and Baidu have been working to produce and test their own self—driving cars.

    Self-driving cars are safer than regular cars. {#blank#}3{#/blank#}They can remove the stress of driving and allow disabled or blind people to get around more easily.

    {#blank#}4{#/blank#}In one test, researchers pointed a laser pointer (激光棒) at the car's sensors (传感器) while it was moving. The car mistakenly thought that the laser beam was in its way and slowed down or changed the direction.

    The software that is used to direct the cars may not be safe enough. {#blank#}5{#/blank#}When we use our computers or smartphones, they sometimes crash (崩溃) without any reason. But if this happened to a self-driving car, the result could be deadly. Improvements to the software could be a solution to this problem.
