Because earthquakes happen without warning, it's important to take steps now to prepare. Because you don't know where you will be when an earthquake happens, prepare some supplies for your home, workplace, and car.
1. Water.
    A person needs at least 1/2 gallon of water daily just for drinking. Store at least 1 gallon of water per person per day and be prepared for a 72-hour period. It is suggested that you buy bottled water. Keep bottled water in its original container and do not open it until you need to use it. Also, do check the “use by” date.
2. Food.
    It's always a practical idea to keep a supply of non-perishable(不易腐烂的) food on hand. Have an enough supply of canned food, powdered milk, dried fruits, non-salted nuts and canned juices for at least 72 hours.
3. Flashlights(手电筒) and spare batteries.
    Keep a flashlight beside your bed, at your place of work, and in your car. Do not use matches or candles after an earthquake until you are sure that no gas leaks.
    Prepare a battery-powered radio and spare batteries. Most telephones will be out of order, so radios will be your best source of information.
4. Clothes.
    If you live in a cold place, you must think about warmth. You might not have heat after an earthquake. Think about your clothing and bedding supplies.

Getting electricity has always been a problem for the 173 people living in Nuevo Saposoa, a small village in Peru, South America. However, things went from bad to worse in March 2015 after heavy rains damaged the only power cables in the area. The villagers were forced to use oil lamps, which are not only expensive but also dangerous because of the harmful gases they produce.

    Luckily, researchers at the University of Technology (UT) in Lima, Peru heard about their problem and found a wonderful solution. They made a lamp that can be powered by plants and soil, both of which can be easily found in the Amazonian rainforest where the village lies. The lamp takes energy from a plant growing in a wooden box and uses it to light up an LED light bulb.

While that may sound amazing and even impossible, the science behind the ides is quite simple. As plants create their food (using the sun's energy, water and chemicals from the soil), they also produce waste which they return to the soil. Tiny animals in the soil eat this waste and they produce electrons – the building blocks of electrical energy. The UT team put special sticks inside the soil to capture the energy and keep it in the lamp's batteries for later use. The researchers say a single charge can power a 50-watt Led light for two hours - enough time for local villagers to get their evening work done.

The university gave ten Plant Lamps to the villagers of Nuevo Saposoa in October 2015. So far, they have been a huge success! Elmer Ramirez, the UT professor who invented the lamp, believes the Plant Lamp could help improve the lives of many people, especially small rainforest communities, 42% of whom have no electricity.

The Internet, mobile phones and Ipads are part of our lives now. Technology is greatly affecting all ways of our lives, from the ways we work to the ways we play. And it even causes a number of social problems such as cloning humans.

    We have had lots of technology and it has changed our lives a lot. There is no doubt that humans will continue to use more and more technology. Here are some examples of modern technology that will change our ideas and will affect our lives greatly.

    Global positioning system(GPS)(全球定位系统)

    It's a system that uses radio signals from satellites to show exact(精确的) information. It tells you where the user is on the earth in all weather conditions. It's made up of three parts: satellites, control equipments(设备) on land and receivers.

    Space Technology

Russian and American scientists have worked together for the international Space Station(ISS) for a long time. They hope the ISS will provide a long-lasting lab. Such a lab will bring humans limitless(无限的) advantages. It's even hoped that one day spare technology will take humans to their new houses in space.

    Underwater Robot

Hercules is a kind of underwater robot with some high technology equipments. It will be used to search for ancient ships which were destroyed into the deep sea during their journey long ago.

The world is changing so quickly that it's hard for us to catch up with all the new inventions because they seem to come out every month. It's important for us to learn about new technology and the role that it plays in our lives. So we should be willing to accept modern technology, or we will fall behind the times.

    You don't have to be a scientist to solve big environmental problems. One Dutch designer is finding creative ways to make a change—and he's inviting bikers to join him.

    Daan Roosgaarde, 38, is a designer from Holland. He uses creative ideas to improve city life. For his Smog (雾霾) Free Project, he designed a special tower that cleans air in Chinese parks. In Holland, he designed a shining bicycle path.

    Now Daan and his team are working with engineers at Chinese bike-sharing company Ofo to create a new product for public use. It's an air-cleaning machine connected to a bicycle and is part of the Smog Free Project. In smoggy weather, the machine would breathe in the air in front of the bike and blow out a stream of clean air toward the biker's face.

    It's no secret that air pollution is a big problem for China. In winter, it's common for thick clouds of haze (霾), caused largely by factory production, burning of coal and car emissions (排放物), to cover areas of China.

    In 2016, only one-fourth of Chinese cities met the country's air quality standards, according to a survey of 338 cities nationwide from the Ministry of Environmental Protection.

    "Of course one tower and a few bikes won't solve China's air pollution problem," Daan said, "But smog-free bikes are an exciting idea that will hopefully inspire communities to create greener cities."

    In England, people often talk about the weather because you can experience four seasons in one day. In the morning the weather is warm just like in spring. An hour 1 black clouds come, and then it rains hard. The weather gets 2 cold. In the late afternoon the sky will be clear, the sun will begin to shine and it will be summer at this time of a day.

    In England, you can also have summer in winter, 3 have winter in summer. So in 4 you can swim sometimes, and in summer sometimes you should wear warm clothes.

    When you go to England, you will see some English people take umbrellas or rain-coats with them on the 5 morning, but you shouldn't laugh at them. If you don't take an umbrella or a raincoat, you will regret later in the day.

Mrs. Brown goes to see her son in London. Her son works in a music club there. Mrs. Brown doesn't know London well. And she can't find her way. 

She sees a man at a bus stop. She wants to ask the man the way. "Excuse me! But can you help me please? Which bus goes to Miller's shop? "Mrs. Brown asks. The man is very friendly. He smiles. But he can't speak English. He can speak French. He is new in London. He puts his hand into his coat and takes out a small book. He opens it and reads something on it, "I am sorry. I can't speak English. "
