At the beginning of 2021, the Chinese government said it will provide free COVID-19 vaccines(疫苗) to all Chinese citizens. Since then, millions of people have gotten the vaccine. Let’s take a closer look.

The vaccine is given by injection (注射). It’s suggested to get two doses. You should wait about two weeks after the first dose to get the second one.

Can people of all ages get vaccinated?

The vaccines have been tested among three different age groups: 3 to 17, 18 to 59, and 60 and above. The 18-to-59 age group has the most data (数据) the vaccines have been proven to be safe in this group. The other two groups are expected to be included soon.

Is there anyone who shouldn’t get vaccinated?

Experts say the vaccines are safe for most people. But people who have serious diseases such as cancer or diabetes (糖尿病), or people who are allergic (过敏的) to any of the vaccine’s ingredients, should not get it. People who want to get the vaccine should not get any other vaccines during the same period.

Do I still need to wear a mask in public places after I’ve been vaccinated?

Yes. It takes a few weeks for the body to build immunity after vaccination. This means it’s possible for a person to get infected (传染的) just after vaccination. There is also a small chance that your body won’t build immunity. So before the population becomes immune to the virus, it’s highly encouraged to keep wearing masks, practicing social distancing (社交隔离) and washing your hands after getting vaccinated.

【推荐2】Turn a book down and hold it up to a mirror. Now try to read the words. With the letters upside down, it’s very difficult to understand. Many people with dyslexia (阅读困难症) see words on the pages this way. Certain letters might look backwards or upside down or the words might seem to “jump” around.

Dyslexia is a condition that influences a person’s ability to read, write, spell, and listen. Someone with dyslexia has a hard time making the connection between the way letters look and the sounds of words. Though learning may be more difficult for kids with dyslexia, it doesn’t mean that they aren’t smart. It means they have trouble translating what they see, hear, or write into meaningful information.

So, what causes dyslexia? Scientists believe a trouble in the brain makes decoding (编译) languages difficult for some people. Although there is no cure for it, some doctors think that if caught early, dyslexia can be improved. One way to do this is by teaching readers to read out words and practise reading. Many dyslexia people discover their own ways, such as listening to books on tape or asking for more time to complete tests.

文章大意:本文主要介绍了几种保护眼睛的方法。
【推荐3】根据短文内容,从短文后的选项中选出能填入空白处的最佳选项。

These days, if we’re not staring at our smartphones, we’re sitting in front of computers. And more than half of office workers have reported the signs of eye strain (眼疲劳). How do you protect your eyes?

Get yearly eye tests. If you work on a computer every day, experts suggest having a complete eye test every year to find problems before they develop.     1     You should also measure the distance from your eyes to your screen at work and tell your doctor.

    2     The closer your phone/computer screen is to your eyes, the harder they have to work to focus. Studies on computer-related eye pressure suggest that screens should be no closer than 40cm from your face.

Take breaks.     3     However, it’s important to try to take regular breaks from staring directly at a screen to give your eyes a chance to rest. It’s suggested that you take a 15-minute break after every two hours spent at your screen.

Make your screen more eye-friendly.     4     You can also increase your smartphone’s refresh speed to ensure less change of the screen, and adjust the screen’s color levels away from the blue end of the spectrum (光谱) and towards the softer yellow end.

A.Give your eyes space.
B.Develop good eyes-using habits.
C.You can make the text larger.
D.This may not always be practical if you have a busy job.
E.During this test, tell the doctor how often you use your phone and computer.
