With such a large rise on mobile phone users around the world over the last 10 years,many people are worried about__1.__ possible problems.For some time,scientists have been thinking that mobile phones could lead to cancer.But so far,there is no strong evidence (证据)for this.

The Norway Institute of Public Health and the UK 's Health Protection Agency both released some studies last year.They said that there was no link found between mobile phone radiation(辐射) and cancer.

However,many mobile phone users often __2.__headaches, dizziness (头晕)and even feeling sick.Last October,a court case (诉讼案件)in Italy said that heavy mobile phone usage had caused brain cancer in one man.He had used a mobile phone up to six hours a day for 12 years. But the biggest problem with research now is that it is too early to reach conclusions.Mobile phones have only been__3.__ used since the 1990s,and cancers can take many years to develop. There is also still a strong argument that mobile phones are a major risk for children."Inner child,small central brain structures are going to be exposed(暴露),"said Dr.Annie,"Besides,kids have a skell(头盖骨) which is_4.__.There is much more water in their brain,so there are many reasons that they take in more of the same radiation."

Although we still don't know whether using mobile phones can cause cancer,we should try to use our phones__5.__.Here are some tips:*Use a headset(耳机) or speaker.

Headsets give out much less radiation than phones.Some wireless headsets give out low-level radiation.However,you should _6.__your headset when you're not talking to anyone.Using a phone with a speaker will also make it safer. *Listen more, talk less.Your phone gives out radiation when you talk or text,but not when you're listening or getting messages.

Answer the questions(根据短文内容回答下列问题)

The Moments (朋友圈)section of WeChat has become a popular part of the

social networking platform(平台).We can share everything about your life on it with

your friends.Some students had a discussion on whether to allow our parents to see

our moments.

Yes

No

Stella, 16:

I think it's meaningful to let parents see

our Moments.Some say that without

parents' involvement(参与),they feel

free when sharing things online.However,as teenagers,sometimes we do need our

parent's guidance,especially in terms of

social experiences.What's more,shutting

them off my make the generation gap (代沟)bigger and bigger,while inviting

them in can help us to communicate and feel closer to each other.

Denny,16:

Most of my friends keep your parents out of their Moments.They argue that if their parents get involved,they will feel upset.However I feel happy when my parents

comment (评论)on my posts in my Moments.It shows

their love and care for me.It also makes them happy and stops them from worrying about me.We'll leave them when we

grow up.Why not cherish(珍惜) every opportunity to interact(互动) with them?

Robin,16:

I don't allow my parents to see my

Moments.Everyone needs some privacy

and we all have our own secrets and

lifestyles.If my parents could see my

posts there,they may push me around

with your ideas,nagging(唠叨) at me to do as they wished,which

would be unacceptable to me even though it would show their love and care.After

all,appropriate distance unites the family better.

Laura,16:

I believe blocking (屏蔽)our parents in

Moments is not a bad idea,as the generation gap can be a great problem.Online social media(媒体) is mainly a way of

communicating with friends of our own

age.We can have more freedom to

develop our thoughts and interests.

Besides,we don't have to worry about our parents' presence.To enable them to read our daily posts would create a lot of

misunderstandings.
