Smartphone and computer are two important inventions in our daily life. They help us in many ways, but they may also lead to health problems.

Looking at the screen of your smartphone or computer for too long can make your eyes dry. It is not good for your eyesight. To help your eyes stay healthy, you can follow the"20-20-20" rule — after 20 minutes' use of eyes, look at something 20 feet away for20 seconds.

Besides our eyes, other parts of our body could also become worse because of using smartphones. When we write a lot of text messages, we can develop" texting thumbs". It will stop us from holding things well. So we have to exercise our fingers and thumbs from time to time.

Scientists also found that smartphones could also hurt our mind. One of the biggest problems is that using smartphones can influence the way we sleep. Doctors say the screen light stops us from feeling sleepy. So they advise people not to use smartphones for at least one hour before sleeping.

Mental problem also needs our attention. Another serious danger caused by staring at screens is Internet addiction (上瘾). Many people turn to the Internet to keep themselves away from feeling nervous, sad or lonely. Over time, they may start to depend on the Internet and feel worried if they' re not online. One way to stop into trouble like this is to control the time they spend on the Internet.

To use your smartphone or computer safely, make sure you follow the above advice. Also, remember that there is more to enjoy in life than just looking at an electronic screen.

(1)、What does the first"20" in the"20-20-20" rule in paragraph 2m ean?
A、How long you use our eyes. B、How often you take a break. C、How far you look at things from you. D、How many things you need to do at the break.
(2)、How many health problems are mentioned in the passage?
A、Six. B、Three. C、Four. D、Five.
(3)、What does the writer advise us to do if we don't want to have Internet addiction?
A、Stay away from bad feelings. B、Control time of use. C、Use in a safe place. D、Stop using the Internet.
(4)、What is the structure of the passage?
A、 B、 C、 D、
举一反三

With our already busy lives, finding time to exercise can be impossible. So maybe it would help if there was ‘a best time' to exercise.

There are clear benefits to exercising in the morning. Many of us have more free time than later in the day, and it may be easier for us to keep a morning plan. A study found that people could sleep better when they exercised in the morning or had the physical activity during the whole day. Exercising on an empty stomach(空腹)before breakfast could also have less fat(脂肪)and keep healthier.

So, good news for early birds, but what if you're not a morning person? Working out in the afternoon or evening is also good, but different. For example, your body's ability reaches the highest level in the afternoon, according to a 2010 study. Also, in the afternoon and evening, your mind is the quickest, and your heart rate and blood(血)pressure are lowest, and you aren't getting hurt(受伤)easily when exercising.

But can this happen? Deciding on if you are a man or a woman? Our bodies are different, after all, so the best time to exercise may be different too. Want to reduce(降低)your blood pressure and you are a woman? Exercise in the morning. Want to improve your heart health and you are a man? Evening is better for you. But, a 2022 study found that it's both OK for them to exercise at either time of day.

So what time is best? It seems the answer is: whatever time is best for you!
