A habit is something that we often do without thinking. And some of them are not good habits. People spend much time 【小题1】 (try) to give 【小题2】 these bad habits but often fail. Why? Change is hard work. However, there is still 【小题3】 (advise) for you to think about.

First, look at why you do it. If your bad habit is shouting at people when you are unhappy, what do you get from it? It may make you feel more 【小题4】 (comfort) for the moment. Or maybe you have a bad habit of leaving your homework undone. The result could be that you get 【小题5】 (much) time to spend on the Internet.

Next, take a look on the other hand. Shouting at other people will make people around you feel bad. Leaving your homework undone, you may be 【小题6】 (punish) by you r teacher. Having more Internet time 【小题7】 (mean) that you are 【小题8】 (lose) the chance to learn the things you need to learn. 【小题9】 is not wise to keep your bad habits. Now it’s time to make a decision. I’m sure you will choose to do something 【小题10】 is more important.

Are you addicted to computer games? Do you stay up all night playing them? There’s no doubt that the 【小题1】   (excite) of games makes people hard 【小题2】   (refuse) them. But should we worry about their effects【小题3】 our health?

If you’ve ever ridden public transport, you’ve probably heard snoring(打鼾) and found someone sleeping in the seat across from you. The natural vibration(震动) of buses and subways 【小题1】(make) us feel sleepy, according to a new study in Science Alert.

Why? It’s all about sensory input-information going to your brain. On a bus, your senses give you 【小题2】(continue) and repeating information. For example, the air conditioner and engine create constant white noise. Meanwhile, you are sitting still and your 【小题3】(surrounding) don’t change. The vibrations of the engine are also opening. Your brain has almost no new information to process.

Repeating information will be 【小题4】(ignore) eventually and your brain will enter a low-energy state. The fact that you fall asleep quickly with your eyes 【小题5】(close) on a bus is because your brain gets used to all the repeat.

“When you’re tired, it doesn’t take much time 【小题6】(start) nodding off and we’ve found that the gentle vibrations made by car seats 【小题7】 you drive can loose(使放松) your brain and body,” said Stephen Robinson, 【小题8】 researcher from the RMIT University in Melbourne, Australia.

Robinson’ s team mentioned 15 volunteers’ heart rate variability(心率变异性)—a well-known indicator of sleepiness. This line of research can assist in the development of practical and relevant guidelines for limiting 【小题9】(expose) to vibrations in the car industry. Robinson believed that the research could be helpful 【小题10】 improving road safety. “We hope that future car seat designs can build in features to disturb this lulling effect and fight vibration-induced(震动引起的) sleepiness,” he said.
