黑龙江省望奎县第五中学2024-2025学年九年级（五四学制）上学期期初考试英语试卷
When you do your homework, you may often meet some problems. How do you solve them? Tom, a middle school student, would take out his smartphone, open a special app (应用) and search the problem. Answers soon appear on the screen.
Nowadays, many students do homework with the help of the special apps like Tom. "It's convenient. You don't have to go out or wait for a tutor at home," Tom said. "You also learn by seeing how others work them out. It's very helpful and improves students' abilities," said John, another student. He said it was especially true for new types of homework.
John's Chinese teacher often asks students to give speeches on great writers. When it comes to John's turn, he usually searches online, picks out certain stories and makes PPTs (演示文稿) . "I've become skilled at finding information online and using Microsoft Office," John said.
However, many people think this trend (趋势) also brings up problems. Some students just copy the answers online without thinking. They become lazy.
Head teacher Mr. Wang in Tom and John's school thinks that knowing how to use the Internet is important. The key is to have good self- control. "No matter how difficult the problem is, think about it by yourself first. Remember not to depend on the Internet too much," the teacher said. "Be sure to understand the reasons behind the answers, or you won't make progress. If you don't have confidence in your self- control, ask your parents for help."
Have you noticed that time seems to pass more slowly when you're waiting in a long line? But when you're playing with your friends, hours seem like minutes. Of course, time is always passing at the same speed--but why does it sometimes feel different?
A study in the Journal of Neuroscience can tell us the answer. Lead researcher Masamichi Hayashi and his research team in the US have found that it has something to do with neurons (神经元) in our brains that are sensitive(敏感的) to time.
The researchers studied the brain activity of 18 adults who were asked to look at a picture on a screen for a certain length of time. They were then asked to guess how long they'd been looking at the picture. They tended to(倾向于) guess incorrectly in the end when they were asked to stare at the picture for very long or very short periods of time.
After researching into their brain activity further, the researchers discovered neurons that work actively in response to(对…有反应) certain amounts of time, which are called time-sensitive neurons. When they receive repetitive stimulation (重复的刺激)(such as staring at a screen), these neurons finally get "tired" and don't work properly. It doesn't matter whether this amount of time is long or short, as long as the stimulation is repetitive. However, other neurons still work normally, having an influence on the ways we experience time.
When you stand in line or do some other repetitive things, such as math homework, your time-sensitive neurons get tired and cause you to feel like time is going slowly. But when you're doing something more fast-changing, such as playing soccer, you feel like time is flying. Either way, you'd better be careful with your brain when it comes to your experience of time. It may lie.
