If you’re a cycling lover, you will have to pay a lot of attention to your bicycle and maintain it well, for bicycle parts are exposed to wear and tear (磨损) over time and you have to examine the bicycle to see if there are any signs of wearing such as scratches, dents (凹陷) etc. Sometimes, a part may not work because it has exceeded its life expectancy. Sometimes, you will need to find replacement parts for it to keep up the performance of the bicycle.
Different parts of a bicycle will wear at different rates so it is very important that you have a basic understanding about the role played by each part. One of the most important parts of the bicycle is the frame. You will need to choose a frame that lasts for a very long time. Of course, you will see some paint scratches after some time. When you’re selecting a frame, you have to think about the material. Aluminium (铝) frames will not rust easily, but they have a higher chance to dent. Steel frames will be hard to dent, but you will need to make sure they get a good paint job so that they won’t rust.
Other parts that you can buy used are seats, handlebars and the stem. When you are buying handlebars, you have to see if there are any dents or if they have been bent out of shape. There shouldn’t be any cracks in the seat post or the handlebars. There are many shops where you can buy parts, so you will have to check the references to see how customers respond to them before you buy anything.

If you stayed up or had a bad night of sleep last night, you know it’s difficult to stay awake in class today. Your teacher’s voice might begin to sound like a lullaby(催眠曲). 1. To keep yourself awake, some tips are worth trying in class.
Sit in the front of the room. Why? 2. Besides, it’ll be easier to pay attention and participate when you’re in the front. You’ll also be near the people who are more likely to participate, and the sound of their voices might keep you awake.
3. Ask and answer questions and pay attention to the lecture. This will help if you’re tired or discouraged by the content of the lecture, because you can ask your teacher questions to get to the bottom of the problems. Talking will also keep you engaged and alert. It might be helpful to make a goal for yourself to answer or ask at least 3 questions per class. 4. For example, you might say “I didn’t understand the last part of the proof. Could you explain it again in more detail?”
Listen actively to the lesson. Active listening is a great way to force yourself to stay awake because it requires engagement of your mind as well as your body. 5.
