湖南省醴陵二中、醴陵四中2017-2018学年高二上学期英语期中考试试卷
The Internet, social media, and smart phones allow you to learn many things.However, just like in the real world, not everyone online is your friend. Some may use these tools to send unpleasant messages to you, and some may use your information to do something bad. It's very important to know how to stay safe and have positive experiences online. Here are some tips for you.
Be careful about friend or follower requests. When you have a friend or follower request, check the person's information first.Only accept friend or follower requests from people you have met in the real world. Don't chat with people you don't know or trust. This is a good way to keep you safe.
Review location(定位) services on your phone and other mobile devices.They may put you in danger because others can find you easily. To make sure of your safety, turn off the "location services" or "locations settings" features on your mobile devices. Also turn off GPS for the camera, chat and other social media apps.
Strong passwords (密码)should have some upper and lower-case letters, numbers and symbols. If you have a strong password, it'll be difficult for others to know it. Also, avoid having the same password for all your social and education accounts (账户). It is really not safe for your accounts.
If someone sends unpleasant messages to you online, find someone you feel safe talking to. For example, you can talk to a parent, a teacher or a trusted adult and ask him to help report and block(屏蔽) the person. Don't try to do the same thing when others do something that hurts your feelings online.
A. Create strong passwords.
B. Try to get help when necessary.
C. Find out if he or she is someone you know.
D. Friend requests can tell a lot of information.
E. Talk to someone you find safe to talk to online.
F. They also allow you to talk with friends online.

Ways to protect eyes from screens
Too much screen time may cause serious eye strain(眼疲劳) and even a sharp decline of eyesight. That's a big problem a lot of people are faced with nowadays, especially those who work on a computer. The following tips may be helpful.
Get regular eye tests.
Experts recommend having a comprehensive eye exam every year to detect (探测) problems before they develop. During this test, you should tell the doctor how often you use your phone and your computer. {#blank#}1{#/blank#}Tell your doctor about it, and your eyes can be tested more accurately at that distance.
Give your eyes space
{#blank#}2{#/blank#} Studies on computer-related eye strain suggest that screens should be no closer than 40cm from your face. If this makes it hard for you to read, consider increasing the size of the text rather than moving the screen closer.
Take breaks
This may not always be practical if you're quite busy, but it's important not to stare directly at a screen for too long. {#blank#}3{#/blank#} While surveys have shown that many office workers take no more than half an hour a day away from their computer, it's recommended that you take a 15-minute break after every two hours spent at your screen.

Staring at a screen continuously for hours on end may make it difficult for you to focus. To avoid this, many eye experts recommend the “20-20-20 rule” --looking away from your phone/computer screen every 20 minutes and focusing on an object at least 20 feet away for at least 20 seconds. The science behind his trick is that looking at objects at a distance relaxes the focusing muscle in the eye. {#blank#}5{#/blank#}.
A. Exercise your eyes. B. Give your eyes a chance to rest. C. Make your screen more eye-friendly D. Studies show it's an effective way to reduce tiredness. E. You should also measure the distance from your eyes to your screen at work. F. The closer your phone/computer screen is to your eyes, the harder they have to work to focus. G. Make sure that you use your phone or computer in a room where the lighting is bright enough. |
