第二节 (共5小题;每小题2.5分,满分12.5分)
You have probably heard of white noise, the sounds that block out other noise and help you sleep. 36 While green noise is actually produced, it copies the relaxing sounds you can find in nature. Green noise uses a low 500 hz frequency(频率) to help you sleep lightly for a short period of time.
Green noise is sweeping social media. It helps people fall asleep faster. But it may not have the staying power to keep you asleep all night like white noise. 37
Besides covering up sounds like traffic or other city noises, green noise can help you reduce(减轻) stress. 38 However, there is scientific information supporting the calming effect of hearing nature. A study showed that people improve faster from a high stress exam when they are in the sounds of nature.
Do you need to buy a green noise machine to help you fall asleep faster? The answer is no. 39 They can be waves lapping on the shore(岸), or soft sounds of trees moving slowly from side to side in the light wind. You can even record your own.
40 Make sure that you try to keep the same bedtime every night. Control the use of caffeine in the evenings and do not eat a heavy meal before bed. You should also stop using screens before trying to get some sleep.
A. Green noise works by using the same idea.
B. There hasn’t been much research on green noise.
C. There is also other advice to help you have a good sleep.
D. Like green noise, white noise is also said to sound natural.
E. Reducing stress before bedtime can help you fall asleep faster.
F. So you may have to experiment to see what works best for you.
G. You can try playing some relaxing sounds of nature on your phone.
