Dear Ashley,
You ask me how to protect your eyesight at your last letter. I am writing to give you some suggestion. Firstly, you shouldn’t keep your eyes work for a long time. After you have studied for an hour or so, you’d better to have a rest and look out of window. Secondly, while reading a book, you should keep your eyes about a foot away from them. Thirdly, keep it in mind what you shouldn’t read in poor light, in strongly sunlight, on a moving bus or in bed. Lastly, doing eye exercises every day help you protect your eyesight.
I hope my advice will be of help to you.
Yours,
Li Hua

Healthy eating habits have positive effects on everyone. However, students can especially benefit from meeting the particular nutritional demands of the school day. To be good academically, children must be physically able to attend class and focus on the tasks at hand. Math, language study, reading and creative thinking also require physical support from food energy and nutrients. 1.
Attendance:2.Getting enough nutrition keeps you from taking sick days and missing out on daily lessons. Eating a healthy breakfast makes you more likely to achieve your daily nutritional goals. This keeps your body strong and less likely to fall ill.
Focus: School is a social network that requires cooperation from students, teachers and staff. 3.Hunger makes you hard to focus and easy to get angry. In contrast, eating a healthy breakfast keeps you focused and cheerful. A 2019 study proved these findings.
Thinking: Food energy and nutrients serve neurological(神经的) as well as physical body functions. The same 2019 report concluded that eating breakfast regularly affects the brain's blood sugar requirements and nutritional support. 4.Let alone, these skills are vital to learning and achieving high grades.
Test scores: Balanced nutrition plays a part in testing well. 5.Healthy eating also contributes to better performance on vocabulary tests. You can improve your test scores by eating right every day.
A.You can focus on the test papers.
B.This improves the memory, problem solving and concentration skills.
C.Students who eat breakfast work faster with fewer math and number errors.
D.You can't keep up with homework and tests if you aren't in school every day.
E.While the education individuals receive influence intelligence, so does their food.
F.And your behavior in this environment depends partly on getting to school well fed.
G.A healthy diet can improve your performance in school’s social, physical and mental aspects.
What’s in the scream? It is thought that the sound of a scream has an acoustic(听觉的) signature - an acoustic DNA that tells the listener’s ear that they are hearing a scream, even if it is not. “The scream may initially run to scare the attacking predator(捕食者). The study of screaming has the potential to help us understand the evolution of emotional communication,” says Jay Schwartz of Emory university.
Jay Schwartz and his colleagues asked 181 volunteers to listen to 75 sounds that included laughter, crying, moans, groans, and yells from acted origins, like television or movies, and more natural sources, such as a YouTube video of a child opening a present and screaming in delight. The listeners indicated whether or not each sound was something they considered a scream. “We did not provide any type of definition for a scream because we were trying to get at what is it in people’s minds that distinguishes a scream,” says Schwartz, who presented his work at a meeting of the Acoustical Society of America on 14 May.
When they analyzed the sound files, they found that the ones listed as screams had acoustic similarities. People were more likely to consider a sound a scream if it was higher in pitch(音高), and had a varied change in pitch, first moving up and then down at the end.
Rapid changes in amplitude - perceived as a rough, gravelly quality - also tended to be classified as screams more than sounds with a smoother tone. This sound was classified as a scream by 64 percent of the listeners. Surprisingly, a recording of a whistle was categorized as a scream by 70 percent of the participants. “It was because the whistle exhibited a lot of the acoustic qualities that we found to be associated with a scream, including high pitch and roughness,” says Schwartz.
1.What was the scream used for in the beginning?
A.Frightening the enemies. B.Sharing the different acoustic DNA.
C.Attracting the volunteers D.Understanding the emotional evolution.
2.What does Jay Schwartz’s research aim to understand?
A.Where people would scream. B.How people judged the scream.
C.Why people would scream. D.What was the best scream.
3.What did the screams have in common?
A.Higher pitch. B.A peaceful mind.
C.Natural origins. D.Different functions.
4.Why was the whistle considered a scream by most listeners?
A.It had the smoother tone. B.It showed some roughness.
C.It made listeners satisfied. D.It did great harm to people.
