III. Reading Comprehension Section B Directions: Read the following three passages. Each passage is followed by several questions or unfinished statements. For each of them there are four choices marked A, B, C and D. Choose the one that fits best according to the information given in the passage you have just read. B Kettlebells do not hurt people. People do. A kettlebell will get your respect – the easy way or the hard way. Here is the easy way. 1. Get a medical clearance. Get clearance, especially from an orthopedist and a cardiologist. The latter is no joking matter, since kettlebell training can be extremely intense. 2. Always be aware of your surroundings. Find a training area with a non-slippery surface on which you are not afraid to drop a kettlebell. The area must be clear of objects you might trip over – including other kettlebells – or that you might hit with a kettlebell. There should be no people or animals in a radius where you could injure them. 3. Train barefoot or wear shoes with a flat, thin sole and room for the toes to spread. Training barefoot is superior for health and performance reasons. If you must wear shoes, wear Converse Chuck Taylors, Vibram Five Fingers, or similar shoes that have thin soles and do not pinch the toes together. You have sensory receptors on the bottoms of your feet that make you stronger and improve balance and coordination. Wearing traditional shoes diminishes the ability of these receptors to work properly, and therefore inhibits performance and can increase the risk of injury. Go native. 4. Never contest for space with a kettlebell. Do not try to save a rep that has gone wrong. Guide the kettlebell to fall harmlessly, and move out of the way if necessary. And remember, quick feet are happy feet. 5. Practice all safety measures at all times. Respect every kettlebell, even the lightest one. Always use perfect form picking up and setting down a kettlebell. The set is not over until the bell is safely parked.

第一周周练习 阅读+完形01 1.阅读短文,从每题所给的A、B、C和D四个选项中,选出最佳选项。 Swimming and English Learning Can you swim? Do you like swimming? Yes? Well, how can you learn to swim? I think the best way is to go into the water and learn. I'm afraid you'll never learn to swim just by reading books about swimming or looking at others swimming. It's the same with the English study. We must practice, practice and practice. Listening and speaking are very important for beginners. The children in English - speaking countries first listen to others. Then they try to imitate and speak. We can listen to English programs on radio. You may just understand a few words. It doesn't matter. Just be relaxed, and try to catch every word. Somebody may be a good listener. But he dare not speak. He's afraid of making mistakes. You know we sometimes make mistakes when we speak Chinese. Don't be afraid. We must be brave. If you really want to learn English well, you must try to speak with everyone so long as he knows English. Whether you know him or not is not important. When there's nobody to talk with, you can talk to yourself in English. It's interesting and also a good way to practice your spoken English. Remember, the more you speak, the fewer mistakes you'll make. Reading and writing are more important for senior school students. First we must choose the books we're interested in. A lot of reading will improve your language sense. This is the most important. Keep writing English diaries. We can also write English articles. You may even post them to English magazines. Don't be afraid of failure. Failure is the mother of success. Easier said than done. Well, let's do more practice from now on. I'm sure you'll learn English well in this way. (1)We should learn English by ________.
