Suppose, you are Sumon/Sumona, and your friend is Rashed/Rasheda. Write a dialogue between you and your friend about the preparation for the JSC Examination to be held in November.

Myself : Hey, Shyamol! Why are you looking so tensed?

My friend : I'm afraid of getting dengue fever.

Myself : I see! Don't worry. Dengue is not always deadly, rather most of the dengue infected people come round soon.

My friend : Really? But how can I understand whether I get dengue or not?

Myself : Very easily. Listen, the symptoms include sudden high fever, severe headaches, pain behind the eyes, severe joint and muscle pain, fatigue, nausea, vomiting, skin rash, and mild bleeding

My friend : Well, what if I have been already infected?

Myself : That's not a problem, too. Doctors may suggest you to take rest and drink plenty of liquids, and sometimes prescribe paracetamol. However, the best ways to prevent dengue fever is to avoid mosquito bites.

My friend : I see! How's that possible?

Myself : Well, we can use mosquito nets and repellents to prevent mosquitoes from biting us, but at first we need to lessen the mosquito population.

My friend : But isn't it difficult to reduce mosquito population?

Myself : Maybe, difficult, but we need to keep our living places and neighbourhoods clean and get rid of stagnant water so that Aedes mosquitoes cannot breed.

My friend : That's great! Thanks for your valuable suggestions!

Myself : My pleasure! Stay healthy!

A : Hi! How're you?

B : I'm well, but worried about the dengue outbreak across the country.

B : Me too. What to do now? Shouldn't we take remedial measures?

A : Of course. It is high time for that.

B : I think the most effective way to prevent dengue outbreak is to prevent bites by the infected Aedes mosquitoes.

A : I agree. We all should use mosquito repellents for that, shouldn't we?

B : Yes, we should. But we have to reduce the mosquito population first.

A : Right! We can do that by destroying their breeding places. Am I right?

B : You're absolutely right! For that, we should keep our dwelling places neat and clean. No stagnant water should be allowed in and around our houses.

A : Besides, we need to use mosquito nets while sleeping. By the way, what should the infected people do to be recovered?

B : It's true that there is no direct cure for dengue. However, doctors generally suggest the infected people to take rest and drink plenty of liquids. Some medicine of paracetamol group is also prescribed.

A : I see. Let's discuss the matter with our friends and start our work against the Aedes mosquitoes.

B : Let's go.

Rana : Hello, Upom! How's life?

Upom : Thanks for asking. I'm doing well. What about you? You look pretty serious.

Rana : I'm thinking about the importance of learning English. What's your opinion about it?

Upom : Well, in today's world the importance of learning English beggars description. It is an international language. Besides, English is the official or semi-official language in more than sixty countries and of many important organizations.

Rana : Right. All the books of higher education are written in English. Moreover, good knowledge of English helps us to get good jobs.

Upom : True. Again, if you go abroad, you've to have the knowledge of English in order to communicate with others.

Rana : That's right. Anyway, got to go now. See you later.

Upom : Okay. Take care.

Sabiha : Hi, Fardin. How're you?

Fardin : Not good at all.

Sabiha : Why? What's wrong?

Fardin: I fall sick very often. I feel physically weak all the time.

Sabiha : Don't you take good food?

Fardin : Well, I can't eat much. I hardly have any appetite for food.

Sabiha : That doesn't sound good. Do you exercise regularly?

Fardin : Nope.

Sabiha : I think that's the reason of your problem.

Fardin : You really think so? Is physical exercise so necessary for us?

Sabiha : Of course! It's essential to keep our body fit.

Fardin : That means - without taking exercise I can't keep fit, right?

Sabiha : Exactly! Regular exercise keeps our blood circulation normal. It keeps us away from diseases. It makes us strong and active. It ensures sound sleep too.

Fardin : Is that so? Then I must take exercise regularly from now.

Sabiha : Remember, a sound mind lies in a sound body. So, if you want to be mentally fit, you must take exercise regularly as it surely will give you a sound body.

Fardin : Thank you very much for pointing out the benefits of physical exercise.

Sabiha : Anytime, friend!

Mubin : Hello. Who am I speaking to?

Rafi : Hi, Mubin! It's Rafi here. This is my personal number. I've got a mobile phone.

Mubin : Really? Now we can talk whenever we like. Isn't that wonderful?

Rafi : Of course. Actually, the utility of mobile phones cannot be described in words.

Mubin : Right. We can keep in touch with friends and family by a mobile phone.

Rafi : Not only that. Internet browsing has become easier due to android phones.

Mubin : Exactly! What a handy thing!

Rafi : But I'm sure it has some bad sides, too.

Mubin : It does, to be honest.

Rafi : Yes. For example, many people often waste their valuable time by talking to their friends for a long time or using social sites.

Mubin : Hmm: It is also disturbing sometimes. There are some students and even some teachers who do not keep their mobile phones switched off during the class hours.

Rafi : Right! I myself experienced that.

Mubin : Do you know that using mobile isn't good for our body, too?

Rafi, : Really? How?

Mubin : So, we must be cautious while using it.

Rafi : OK, Mubin. We shouldn't talk over phone for long too. Take care and see you tomorrow.

Mubin : Ok, Rafi. See you! Bye!

Rafi : Bye.

Safwan : Good evening, Doctor!

Doctor : Good evening, dear! Tell me what your problem is.

Safwan : I have been ill for the last few days. I have been suffering from fever since Monday last. Sometimes, temperature gets really high.

Doctor : Hmm. Have you caught cold, or do you have sore throat?

Safwan : Yes, I've been sneezing all the time. I can't eat anything easily, not even liquid. It really hurts. Also, I can't feel any taste in my mouth.

Doctor : I see. Let me check your body temperature first... Now, show me your tongue ...... Okay, now relax.

Safwan : What do you think, Doctor? Anything serious?

Doctor : Nothing to worry. It's simple viral fever. Just follow some rules. Take enough rest, drink sufficient water and take these medicines twice a day for five days; you'll be fine soon.

Safwan : Oh, that's a relief! Thank you very much, Doctor.

Doctor : Welcome and take care.
