I shall never forget the day when the earthquake happened. It was about 5 in the afternoon and I was1along the road to my daughter's school. Our plan was to go2together. I stopped at a3to get some fresh fruit. We liked to have some fruit to eat after our swim. I was driving along a high4on my way to the school.5my road was another road which was built like a6. I was7so I put the bag of apples8 me and started to eat one. Suddenly I saw the cars in front of me start to9from side to side. I slowed down. Then my car started to shake! I didn't know what was happening. Perhaps something had10wrong with my car. I drove a little more slowly and then I 11the car and at the same moment the road12onto the cars in front of me. I found myself in the13. I couldn't move. My legs and feet were hurt badly and I couldn't move them. All around me was14But below me I could hear shouts and a lot of noises.
Then I realized what had happened. I had been15an earthquake. For about two hours nobody came. Luckily I could reach the bag of16, so at least I had plenty to eat. Then I heard people17towards me. A team of people had come to18if anyone was under the19road. I called out," I'm here!" I heard a shout. Soon a stranger climbed to my car. "How are you20?" he asked. "Not too bad," I said. They didn't get me out until the next morning.
European researchers say they have created a process that can produce oxygen from moon dust. The process could provide a major source of oxygen for humans taking part in moon exploration activities in the future. Researchers from the European Space Agency, or ESA, carried out the experiments at a laboratory in the Netherlands.
The team says ESA's experimental "plant" was able to successfully produce oxygen from simulated moon dust. The dust is part of a material known as regolith, a top layer of dirt and rock pieces that sit on the surface of the moon. Samples of regolith returned from the moon have confirmed that the material contains about 45 percent oxygen by weight. However, the oxygen is chemically locked in the form of minerals or glass, so it is not easily available for use. Having real samples of regolith from the moon made it possible for the researchers to create the simulated moon dust material used during testing.
The oxygen extraction(提取)process is carried out using a method called molten salt electrolysis(熔盐电解). This includes first placing the regolith in a metal container. Calcium chloride salt is added to the mixture, which is then heated to 950 degrees Celsius. At this temperature, the regolith remains solid. Next, an electrical current is passed through the material. The researchers say it is this step that results in oxygen being extracted from the regolith. The study reported that up to 96 percent of oxygen in the simulated moon dust was extracted during the experiments.
ESA's long-term goal is to design an oxygen-producing "pilot plant" to operate full-time on the moon. The first technology demonstration of the system is expected to take place in the middle 2020s. Beth Lomax, a lead researcher on the project, said, "Being able to acquire oxygen from resources found on the moon would obviously be hugely useful for future lunar settlers, both for breathing and the local production of rocket fuel. "The researchers reported that" as a bonus, "the process also results in the production of usable metallic materials.
ESA and the US space agency NASA are both working on plans to return human beings to the moon. NASA has set a goal for 2024 with the aim to keep humans on the moon for long periods.
How to Love Your Parents?
You love your parents for the fact that they created you, raised you, and are in part, a source of who you are. .
Respect them more and value these moments. You can use these moments to learn from them, preparing yourself for when you're off on your own. It's OK to get angry but angry actions don't help you or your parents. Act calmly, cool off, write down your feelings, or talk to a friend. .
Obey their requests. It will make your attitude better and earn you more respect from them. It may seem like you are going through hell when you don't get what you want or you have to clean. However, you had better remember they keep a roof over your head when it's cold, raining, snowing, or too hot. Understand that parents are human beings and make mistakes. Since you can forgive (原谅) your friends, why not forgive your parents?
Keep company with them. Do things with your parents like watching TV, or going somewhere with them. Listen to their old stories and learn from them. You will find they are your teachers in this way or another.
Tell them you love them every morning.
A gentle “good morning” and “I love you” will warm a coldest heart. Without your parents, you cannot come to this world.
A. Forgiveness is the key.
B. Here are some ways to love your parents.
C. Parents will in turn express their love to you.
