                                                                                       SOCIAL MEDIA AND FRIENDSHIP

 

   Having too many friends does not sound like the kind of thing anyone should really be too concerned about. After all, what can be wrong with having a wider group of people to hang out with? According to the latest figures, the average number of friends people have with social media is somewhere between 200 and 300. (1) __________ But is this a realistic amount? Is it feasible to maintain meaningful relationships with so many people, in particular those you may never actually meet in person? 

   Nowadays, we are just one click away from making new friends on social media. (2) __________ For instance, when I see that a friend has updated their profile with snaps from their latest holiday, I'd typically reply with a comment like “Wow, looks great!” even though in actual fact, it doesn’t. The unwritten agreement is that the next time I post, that friend will respond with a similarly appreciative comment, so I’ll feel better about myself. 

   Not long ago, I got chatting to someone at a concert, who told me that she loved going to gigs. We got along pretty well that evening, even though the music was so loud! We even swapped numbers and added each other on social media. Now, I see her pop up in my feed now and again and I ‘like’ her photos from various gigs she’s been to, but I’m pretty certain that we’ll never arrange to meet up in real life. 

   (3) __________ That being said, we’re living in a time where we expect things to happen instantly, so is it really all that surprising that the way we form friendships has adapted to this trend? Perhaps it shows how social media has made friendships less sincere, reducing them to a series of meaningless ‘adds’ and ‘likes’. 

   Real friendships, on the other hand, take time to build. My most important relationships haven’t grown out of a few trivial online exchanges. (4) __________ And these for me - and I believe for most other people too - are much more valuable and meaningful. It’s something that cannot be replicated on social media, no matter how many times you have ‘liked’ a person’s posts. 

   It has been suggested that technology is ruining our relationships with other people. (5) __________ However, it seems undeniable that it has now altered people’s priorities, and transformed the way that we manage our friendships in the most fundamental ways. Ultimately, though, it’s up to us to decide how real and meaningful those friendships truly are.

+ SENTENCES:

A. Personally I wouldn't go so far as to say that.

B. Research suggests that this figure is actually higher for teenagers. 

C. Social media has made this kind of problem increasingly more common.

D. It's taken years of shared experiences to develop strong and lasting bonds.

E. This has led some people to question just how sincere the friendship is.

F. It could be argued that this is just another example of how life has changed in recent years.

(Đọc văn bản. Nối các từ được đánh dấu với nghĩa của chúng.)

There are two types of community service. The first one is a kind of punishment. For example, people who litter may be forced to clean up the streets. In this case, they may not feel happy about the work. The second type of community service is voluntary. This means people are willing, or pleased to do the work. For instance, people may volunteer to build houses for poor people, or raise money for children in mountainous areas.

However, it does not mean that volunteering is always a selfless act because volunteers may also benefit from the volunteering activities. For example, they may volunteer to meet new people, to develop social skills, or to find themselves' (learn what they truly want in life). In general, people may volunteer not just to help others, but also to help themselves.

Read the text below and choose the correct answer A, B, C or D to each question. Write your answers A, B, C or D on your
answer sheet.
Different Colours can affect us in many different ways; that’s according to Verity Allen. In her new series ‘Colour me
Healthy’, Verity looks at the ways that colours can influence how hard we work and the choices we make. They can
even change our emotions and even influence how healthy we are.
‘Have you ever noticed how people always use the same colours for the same things?’ says Verity. ‘Our toothpaste
is always white or blue or maybe red. It’s never green. Why not? For some reason we think that blue and white is
clean, while we think of green products as being a bit disgusting. It’s the same for businesses. We respect a
company which writes its name in blue or black, but we don’t respect one that uses pink or orange. People who
design new products can use these ideas to influence what we buy.’
During this four-part series, Verity studies eight different colours, two colours in each programme. She meets
people who work in all aspects of the colour industry, from people who design food packets, to people who name
the colours of lipsticks. Some of the people she meets clearly have very little scientific knowledge to support their
ideas, such as the American ‘Colour Doctor’ who believes that serious diseases can be cured by the use of
coloured lights. However, she also interviews real scientists who are studying the effects of green and red lights on
mice, with some surprising results.
Overall, it’s an interesting show, and anyone who watches it will probably find out something new. But because
Verity is goes out of her way to be polite to everyone she meets on the series, it is up to the viewers to make their
own decisions about how much they should believe.

1. What is the writer doing in this text?
A. giving information about how colours influence us
B. reporting what happens in a new television series
C. giving information about a television presenter
D. giving his opinion of a recent television show
2. Which of the following shows the probable content of the four shows?
A. Part 1 – Health; Part 2 – Products and Industry; Part 3 – Emotions; Part 4 – Decisions
B. Part 1 – Blue and Black; Part 2 – Red and Orange; Part 3 – White and Grey; Part 4 – Green and Yellow
C. Part 1 – Meeting Designers; Part 2 – Meeting People who Name Colours; Part 3 – Meeting Doctors; Part
4 – Meeting Scientists
D. Part 1 – Cleaning Products; Part 2 – Make-up; Part 3 – Clothes; Part 4 – Food
3. According to Verity, why is a knowledge of colour important?
A. It can help you to choose the best products.
B. It can give you new ideas.
C. It can help you to change people’s minds.
D. It can help you to sell products.
4. Who does the writer respect least?

Be happy!

There have been lots of surveys about teenagers and happiness and they all come to different conclusions. Some surveys say that most young people are happiest when they spend time with their family. Others say it's when they're with friends. Some teenagers think that getting good marks at school and passing exams make them happy, while others feel that it's having a boyfriend or girlfriend. The problem is that there isn't just one thing that makes everyone happy, and what made you happy last week might not make you happy next week! However, there are some things that can help improve your mood when you are feeling unhappy. Experts believe that exercise can make you a happier person because it releases chemicals in your brain that are related to a feeling of pleasure. There's another surprising idea to help make you happier. Although you might think that eating chocolate is bad for you, it seems, according to some experts, to be good to eat chocolate when you're feeling sad. Of course it isn't healthy to eat too much, but chocolate releases chemicals in the same way that exercise does - and for some people it's easier and quicker than working out in the gym! It's also important to remember that you can’t be happy all the time. You can be happy for brief moments and you should value these times. And when you feel sad, go for a run or eat some chocolate - you'll soon cheer up!

2. The things that make us happy never change. T F DS 

3. The surveys show that teenagers who do exercise are happier. T F DS

Country music is sometimes called country-western music. It comes from two kinds of music. One is the traditional music of the people in the Appalachian Mountains in the eastern United States. The other is traditional, cowboy music from the American West. The singers usually play guitars or electric guitars when they sing.

Country music became very popular in the South. During World War II, thousands of people from the South moved to the Northeast and the Midwest to work in factories. They took their music with them.

a. Environmental problems: What are they?

b. Environmental protection: How important is it?

c. Environmental solutions: How practical are they?

The environment we live in is facing many serious problems. We need to be aware of these problems so that we can find ways to protect nature.

A. Global warming is the rise in the average temperature of the earth's atmosphere. It is one of the biggest issues facing humans today. It can have serious consequences such as rising sea levels, polar ice melting, and extreme weather events like floods or heatwaves.

B. Another environmental problem is the cutting and clearing of natural forests. The loss of forests can have a negative impact on the environment. It can damage the natural habitats of many animals and put wildlife in danger. It can also destroy the natural soil and lead to climate change.

C. Air pollution is also a serious problem. It is mainly caused by waste gases that come out of vehicles, machines, or factories. When these harmful gases combine with the water in the air, they come down as rain or snow, which can damage all forms of life. In addition, this problem leads to global warming and climate change. It is also a major cause of respiratory diseases or even lung cancer.

D. Around the world, the number of endangered animals is rising. Many of them disappear because of pollution and climate change. In addition, humans illegally hunt and kill animals, and catch too many fish at once. This is upsetting the natural balance of ecosystems, which can be harmful to all living and non-living things.

Nó có thể gây ra những hậu quả nghiêm trọng như mực nước biển dâng cao, băng tan ở hai cực và các hiện tượng thời tiết khắc nghiệt như lũ lụt hoặc sóng nhiệt.

B. Một vấn đề môi trường khác là chặt phá rừng tự nhiên. Việc mất rừng có thể có tác động tiêu cực đến môi trường. Nó có thể làm hư hại môi trường sống tự nhiên của nhiều loài động vật và khiến động vật hoang dã gặp nguy hiểm. Nó cũng có thể phá hủy đất tự nhiên và dẫn đến biến đổi khí hậu.

C. Ô nhiễm không khí cũng là một vấn đề nghiêm trọng. Nguyên nhân chủ yếu là do khí thải từ xe cộ, máy móc hoặc nhà máy. Khi những khí độc hại này kết hợp với nước trong không khí, chúng sẽ tạo thành mưa hoặc tuyết, có thể gây hại cho mọi dạng sống. Ngoài ra, vấn đề này còn dẫn đến hiện tượng nóng lên toàn cầu và biến đổi khí hậu. Nó cũng là nguyên nhân chính gây ra các bệnh về đường hô hấp hay thậm chí là ung thư phổi.

D. Trên khắp thế giới, số lượng các loài động vật có nguy cơ tuyệt chủng đang tăng lên. Nhiều con trong số chúng biến mất vì ô nhiễm và biến đổi khí hậu. Ngoài ra, còn vì con người săn bắt và giết động vật một cách bất hợp pháp và đánh bắt quá nhiều cá cùng một lúc. Điều này đang làm đảo lộn sự cân bằng tự nhiên của các hệ sinh thái, có thể gây hại cho tất cả các sinh vật sống và không sống.
