While new phones are advertised as “water resistant (防水)”, this doesn't mean they are waterproof, or totally immune to water. Water resistance just implies the device can handle some exposure to water before substantial damage occurs.

The water resistance of phones is rated by an “ingress (进入) protection” code, commonly called an IP rating. The rating includes two numbers. The first demonstrates protection against solids such as dust, while the second indicates resistance to liquids, specifically water. a phone that has a rating of IP68 has a solid object protection of 6 (full protection from dust, dirt and sand) and a liquid protection of 8 (protected from immersion in water to a depth of more than one metre).

The popular iPhone 12 and Samsung Galaxy S21 phones both have a rating of IP68. However, regarding exposure to water, the iPhone 12 has a permissible immersion depth of a maximum of 6m for 30 minutes whereas the Galaxy 21's immersion limit is up to 1. 5m, also for 30 minutes.

While IP ratings indicate the water-resistant nature of phones, taking most phones for a swim will land you in deep trouble. The salt content in oceans and swimming pools can corrode (腐蚀) our device and cost you a heavy replacement.

Then how to fix a water-logged phone? Follow these steps: First, turn off the device immediately and don’t press any buttons. then wipe the phone dry with paper towels or a soft cloth and gently shake the device to remove water from the charging ports. Next, remove the SIM card and dry out the phone in front of a fan. Do not charge the phone until you are certain it's dry.

If the above steps don’t help and you're still stuck with a seemingly dead device, don't try opening the phone yourself. You're better off taking it to a professional.

1. What can you infer from Para. 2?
A.The water resistance of phones is evaluated by an IP rating.
B.The rating is made up of several numbers.
C.The first IP rating number indicates resistance to liquids.
D.A phone with a rating of IP68 has a solid protection of 8.
2. What does the underlined word in Para. 4 refer to?
A.Things are not made by people.B.The way that things happen.
C.The way of an act of a person.D.The basic qualities of a thing.
3. What should we first do with a water-logged phone?
A.We should pick it up from the water.
B.We should ask a professional for help.
C.We should switch it off and don't use it.

4. what is the passage mainly about?

【推荐1】How To Deal With A Bully

A bully is someone who, out of habit, uses their power to hurt or frighten other people. They enjoy doing physical and emotional harm to others and often leave the victim feeling helpless.     1    . However, these suggestions below can stop the situation from worsening.


Ask Them To Stop

Asking the bullies to stop in a firm and confident voice is sometimes an effective measure to deal with them. Sometimes when we do not speak up for ourselves, the bullies continue with their behavior thinking of us as easy targets. In this thought, they assume that we will never speak up to them.     2    .


Be Accompanied

    3    . If you are with your friends, or if you are in the company of someone, it is less likely that the bully will disturb you. We are not asking you to make a huge circle of friends. Sometimes, all it takes is one loyal friend who will stay by you no matter what.


Turn The Situation Into A Joke

Some of us are born comedians and we can turn almost anything into a joke.    4    . Turn the situation the bully has created into a joke or just say something funny. This will break the bully’s confidence and they will know that you are strong and sure about who you are. This will make them back off.

It is never easy to deal with all the unwanted bullying even when you have done nothing wrong.    5    . So be brave and take action now!

A.Bullies usually hunt for people who are alone
B.There is no simple solution when it comes to bullying
C.It’s a brilliant idea to make as many friends as possible
D.But doing nothing will only result in more intense bullying
E.If you are one of these people, try to make full use of your gift
F.So when we do speak up for ourselves, it takes them by surprise
G.Whatever they do, remember you are not responsible for their actions

【推荐2】The Best Ways to Lose Weight with Walking

Walking regularly is the easiest and least expensive form of exercise. Except for a good pair of walking shoes, no special equipment is needed. It is not necessary to join a gym.     1    You can walk every day with no “rest days” in between. There is nothing to learn; people already know how to walk. There are, however, a few important things to keep in mind when walking to lose weight.

● Ways to lose weight by walking

The first way to begin to lose weight by walking is to start walking. The initial goal should be 10,000 steps per day. Using a simple pedometer(计步器) attached to the waistband or on a belt will help you to count your daily steps. Consistency—even 10 minutes 3 times a day at first will produce the immediate results.    2    

    3    

It is very important to check with your medical professional before beginning any exercise program; especially if you are over age 65, have been required sitting or little activity for more than a year,or have been diagnosed with heart disease,pregnancy,high blood pressure,or any other medical conditions.

● How to walk to lose weight

A good walking technique will help you achieve the physical or mental energy you need to walk consistently for the amount of time you have set for your goal. Making sure that you are using your large muscles correctly will also help to build your muscles.    4    

Walking regularly can aid in muscle growth and increase the amount of calories you burn throughout the day. Eating a healthy low-fat diet will raise your metabolism(新陈代谢).    5    If paired the calorie burn with the correct diet, it can lead to a better form of weight loss.

A.Limit your "bad" fat intake.
B.Begin a walking program with suitable physical qualities.
C.For example, take the stairs rather than taking the elevator.
D.It can be done anywhere and anytime, alone or with friends.
E.These two methods will help lead to a safe 1 to 2 pound weight loss per week.
F.Strong muscles burn more calories throughout the day, even when you are not walking.
G.But slowly increasing the time and the distance will encourage your weight-loss efforts.

文章大意:本文是一篇说明文。文章主要介绍了如何恰当地表扬,才能养成正确的价值观。

【推荐3】A patient and I are working on an eating disorder, trying to find out the cause. It turned out to be a relationship break-up in high school. The unpleasant experience led to not eating for a couple of weeks. Then comes a compliment (赞美) from a friend that totally has the opposite effect. “Wow, you look great!” Suddenly, this praise inspires an inner thought: “Oh, people care more about me if I lose weight. So I can control people’s affection by not eating.”

Consider busy parents who don’t notice their child until a good grade appears. In the absence of attention and connection, a sudden strong expression of well-intended praise can bring about the thought, “Wow, my grades make me valuable. I’m noticed when I achieve!” The result can be a twisted view of self-value and an anxiety around grades, exams, and performance. A similar situation occurs with athletic success or high praise for being “nice”. The result is a false mindset: “My worth is totally tied to this desirable behavior.”

So what’s a better way? One answer is to exit the game of “right and wrong” and enter a focus on what needs are present. Returning to our example above, when you see someone has lost weight and you want to give them a compliment, just pause and simply ask, “How are you doing?” See them and hear them. Appreciate them as a person of great value. There may be much more to their inner world than meets the eye.

Similarly, when you see someone’s success, appreciate the hard work they put into it. Ask with gentle curiosity, “How’s it been for you?” Listening with full attention can be a rare gift in today’s world. See if you can understand them from the bigger frame of what they’ve experienced, how they’re feeling, and what they’re needing now.

1. What can we learn from paragraph 2?
A.It’s parents duty to care for their children.
B.A strong expression of praise should be prevented.
C.Well-intended praise can result in unwanted results.
D.Praise from parents encourages kids to work harder.
2. Why should we avoid misused praise?
A.It is not favored.B.It makes people proud.
C.It underestimates human value.D.It fails to cheer people up.
3. Which of the following can be a better praise?
A.It’s so kind of you to help me with my work!
B.I appreciate your great efforts to get there!
C.You always perform best among us!
D.You look young for your age!
4. What is the author’s attitude toward praise?
A.Doubtful.B.Unclear.C.Indifferent.D.Approving.
