A

Boys and girls, let's do an experiment（实验）in today's lesson.

Materials:

    

Instructions:

1. Fill the glass or jug about 2/3 full with water

2. Drop the egg carefully into the glass and watch it going down towards the bottom.

3. Take the egg out and add about 5 spoons of salt. Test to see if your egg goes up.

4. Add more salt if the egg is still at the bottom.

The science behind it:

Things go down in the water when they are denser than the water, and by adding salt we make the water denser. Once the water is denser than the egg, it goes up.

You can also try other things to see if you can have the same result.

（　　）11. What kind of lesson are the students having?

A. Maths.           B. Biology.           C. Physics.            D. Geography.

（　　）12. Which of the following is the result you can see after adding salt in water?

                           

A                   B                   C                   D

（　　）13. What does the underlined word "denser" in Part 3 probably mean?

A. Faster.            B. Slower.           C. Lighter.           D. Heavier.

B

It may sound strange, but many people play noise to help themselves sleep better. Actually, this kind of noise is called coloured noise, such as white noise, pink noise, and brown noise.

Coloured noise contains a wide range of frequencies（频率）. However, it shows stronger intensity（强度）at certain frequencies. For example, violet noise has stronger intensity at higher frequencies. Brown noise produces deeper sounds such as heavy rainfall, because it shows stronger intensity at lower frequencies. White noise has equal intensity across all frequencies. Typical examples of white noise are the noise made by fans, and natural sounds like gently running water. Pink noise is similar to white noise but has stronger intensity at lower frequencies.

There have been several experiments on the effect that noise has on people. In a 2021 study, 10 people in New York City affected by loud environmental noise showed improved sleep quality and sleep duration when white noise was played. Another sleep study showed that 16 adults actually

improved their memory of vocabulary after listening to pink noise in their sleep, though the effect of pink noise on sleep quality wasn't measured. Some people suggest that brown noise is the best noise for their sleep. However, no studies have proven （证明） it.

So why do some people claim to sleep better with certain coloured noise? There are some theories that can explain it. One is about sound masking, and it shows that white noise masks other sounds of noise, resulting in better sleep. Another theory is that this sleep-aid effect could be an example of classical conditioning. For example, people who sleep better with brown noise may have conditioned themselves over time to fall asleep when they hear it.

Every coloured noise has its benefits（好处）. It is your personal choice to decide which coloured noise is the best for you to get a good sleep!
