If you want to keep healthy, you should have good habits. What is a habit? It is something we do very often. We don't even think when we do it. It has become a part of our lives. "Early to bed, early to rise makes a man healthy, wealthy and wise." This is an old English saying. Do you know what it means? It means that we must go to bed early at night and get up early in the morning. If we do, we shall be healthy, rich and clever. Is this true? Perhaps it is. We know the body must have enough sleep. Boys and girls need eight or nine hours' sleep every day. Some people go to bed late at night and get up late in the morning. This is a very bad habit. Then you will not think or do your work well. Of course, you can't be healthy, wealthy or wise. When we get up early in the morning, we can go out and do morning exercises. Exercise means doing things with the body. Walking, running jumping, swimming, and playing ball games are all exercise. If we don't exercise, our body will become weak. Exercise helps the blood to move around inside our body. Blood takes food to all parts of our body. Our body also needs air to breathe. Without air, we will die. We must have lots of clean fresh air if we want to be healthy. That is why many people like to go out to do morning exercise. Which sport is NOT mentioned in the passage? A) Jumping. B) Swimming. C) Riding. D) Running.

Governors, lawyers and business leaders have to deal with scientists, and every educated person finds his views affected by science. Yet our science teaching of non-scientists, in school and college, has built up mistaken ideas, dislikes, and the common boast, "I never did understand science.' Even those students who arrive at college with plans to become scientists usually bring a mistaken picture of science: some have a collection of unorganized facts about science, and some regard the study of science as a game which includes getting the right answer. The first of these attitudes seems to come from a kind of course which provides various kinds of information; the second, from a training course on how to pass examinations that do not ask about the student's understanding but simply require him to put the numbers in the right formulas . Neither type of courses (in school or college) seems to give students and understanding of science as we find it among scientists. Neither shows students how real scientists work and think how the facts are gathered, how discoveries are made, and what they mean. Young people need good teaching of science, not so much a great wealth of knowledge as a healthy understanding of the nature of science. They need an understanding of knowledge leading to sympathy with science and an eagerness of the way scientists work. Given these, it is easy to encourage later reading and learning. People such as governors, lawyers and business leaders deal with scientists mainly because _ . A) scientists are great persons B) scientists make discoveries and apply them to help people live a more comfortable, stable and safe life C) they owe much to scientists' contributions D) they can be affected by scientists when they are together

Q: As I sit at home thinking about my upcoming adventure and the things I need to bring, it makes me even more excited to begin my travel. I will be making my way around the world. The first places on the list are Andalusia and Africa in the book The Alchemist. I will need to pack a lot of things and make sure I have enough money to provide myself with food and enough to drink. The Sahara desert is always hot and requires plenty of water. Next I will head to Mexico in the bookBorn to Run, where I will meet the Tarahumara Indian tribe . I will need to get into shape and do some jogging if I want to keep up with them. I will have to pack my running shoes, though, because the Tarahumarans have mastered the art of running on the tough land. After Mexico, my journey takes me to the Egyptian desert in the novelThe Paris Vendetta. There I hope to help uncover an ancient conspiracy that goes back centuries. Just like my trip to Andalusia, I will have to make sure I have plenty of water. Packing the Camelbak products seems like the best idea, so I will have enough on hand at all times. I expect this adventure to be quite interesting, and I am very excited about it. Lastly, I will make my way back to America in the bookShattered: Struck Down, But Not Destroyed. This makes me feel excited because like the main character in the book, I also wanted to become a professional athlete when I was younger. For this trip, I will go with an open mind and hopefully meet some friends along the way. I am ready to _ my adventure of traveling, and I cannot wait any longer! The Camelbak products are probably made to _ . A) help people find out the truth B) supply people with water C) protect people from the sun D) show people the right direction
A: B
(Question)
Imagine life without the Internet -- not being able to chat with your friends or look up information for your homework or research project. That is the reality for nearly two-thirds of our world's population, either because they cannot afford WiFi access or are located in remote, inaccessible areas. Now Google has decided to do something about that. Google's Project Loon will attempt to send balloons high up into our earth's atmosphere in 2015. Each balloon will be equipped with a mini computer and a WiFi radio that will send Internet signals over the places it is floating over. The network equipment on Google balloons will communicate with a special antenna attached to each user's home. These antennae are in turn connected to a local Internet Service Provider. Each balloon will also communicate with each other to hand over signals as one floats out of an area, and another floats in. The balloons are 15 meters wide and made of a material that is three times thicker than the plastic bag at the supermarket. This helps them defend themselves against cold temperatures and changing air pressure. Google balloons will circle the earth at a height of 20 kilometers-- in a layer of our atmosphere known as the stratosphere . This is higher than the altitude at which planes fly. Once the balloons reach the desired altitude after being released from the earth, they will ride on air currents. What keeps these balloons from flying away? They will be controlled by people at the Project Loon command center. A pump operating on solar power will fill the balloon with gas to raise it or let gas out to lower it, based on instructions. This allows the balloon to float on different air currents which are moving either clockwise or anti-clockwise. There is no doubt that this technology can bring education to many children, weather information to farmers, and communication to natural disaster areas. However, one big question remains -- will some countries be comfortable with balloons above their heads? There could be concerns... What's the purpose of Google's Project Loon? A) Sending Internet signals to other planets in space. B) Making it easier for astronauts to communicate. C) Allowing people to connect to the Internet easily. D) Helping us learn more about the earth's atmosphere.
