Suggested answer:

I'm happy to have received your email. I'm going to tell you about the things I like in my community.


The first thing I like about it is the people. They're kind and friendly. They're willing to help one another
when it's necessary. When we moved here three years ago, our next-door neighbours came to our
house and said hello. They also told us where to buy things for our house. Another thing I like about
my community is that it's very convenient. It's close to many facilities such as shopping malls, schools,
and cinemas. When we need a service, we can get it immediately.
That's all for now, Mark. Tell me about your community.
Cheers

convenient. I can get around the city by bus and metro.

Suggested answer:



Wonderland is a city near the mountain. In the past, it used to be a small and poor town. There were no
high buildings at all. The streets were narrow and empty most of the time. Not many people lived there.
Nowadays, Wonderland is a modern city with many high buildings. There are huge entertainment
centres, many good department stores, and a big modern library downtown. The public transport
system is excellent with clean buses and convenient sky trains. People in Wonderland think that it is
a liveable place. Teenagers and young adults enjoy the exciting life here. Meanwhile, adults and the
elderly like it because the cost of living is reasonable.

you should prioritise tasks and set realistic goals. You should also learn to say no to unnecessary
commitments and tasks. In addition, communication and time management are important to
maintain relationships with your family and friends. You should schedule time for socialising and
keeping in touch with your family and friends even when you are busy. Finally, you should practise
relaxation techniques such as meditation, physical exercises, etc. to manage stress and anxiety.
By following these practices, you can maintain a well-balanced life that supports your overall health
and happiness.

30. A: The noun “retreat” is often used as a singular countable noun, especially with an adjective

281

32. C (she constructed → to construct): The correct structure is: to teach somebody how to do

36. D: The phrasal verb “to remind somebody of something / somebody else” means “to make
somebody remember somebody else that they know or something that happened in the
past”.



37. A: We normally use the double comparative structure to express cause and effect:

Therefore, sentence A is the only correct answer; other options are wrong grammatically or not
logical in meaning.


38. D: The phrasal verb “to cut down (on something)” means “to reduce the size, amount, or
number of something”; we use the structure: “to advise somebody to do something”. Therefore,
sentence D is the only correct answer; other options are wrong grammatically or not logical in
meaning.



39. C: The phrase “in case of something” is normally used to describe what you should do in a
particular situation, especially on official notices. Therefore, sentence C is the only correct
answer; other options are wrong grammatically or not logical in meaning.



40. C: We normally use “may” in the main clause of first conditional sentences to express possibilities;
the phrase “good at something / at doing something” means “able to do something well”.
Therefore, sentence C is the only correct answer; other options are wrong grammatically or not
logical in meaning.

Keeping our traditions and customs alive is very important for us, and people in my neighbourhood
have several ways to do this. Firstly, we hold the festivals of our country and the area such as the MidAutumn Festival and the New Harvest Festival. Secondly, we worship our ancestors, and we celebrate
their death anniversaries every year. This helps express our respect and gratitude to them. Thirdly, we
keep cooking and enjoying traditional food, especially on special occasions like the Lunar New Year.
Moreover, we regularly teach children about the importance of observing traditions and customs. By
doing these things we keep our rich culture alive, and pass it down to the next generation.

My most pleasant experience was a time with my friends one morning. We had only two lessons, so
we decided to see a film after school. We called our parents for permission before going. The cinema
was about three kilometres from our school. Phong and Vinh chose to cycle because it was more
convenient for them. Nam and I decided to catch a bus. Wonderfully, the bus was air-conditioned and
there were no other passengers because it was about 11 a.m. We felt that the bus was just for the two
of us. The bus fare was inexpensive, and we even got to the cinema before Phong and Vinh did. The
film was also thrilling, so we all felt that we had a great morning together.

Suggested answer:



About three years ago, I was a shy boy. It was hard for me to express what I thought, so I could not
communicate well with friends and teachers in class. I became reserved and avoided taking part in
group activities. I wanted to change it. Last year, I did an online course on public speaking. It taught
me how to arrange ideas and express myself. It connected me with others on the course. Gradually I
became more confident. Now I join in my friends' talks and take part in class debates. I am happy now
and feel thankful for the change.
