HW 51/EX1:Hello. My name is Lucy. Last week I went to visit my friend Samantha in Spring Town.
That was my first visit to Spring Town, and I rode my motorbike to Samantha’s house. Firstly I saw a
No U-turn signal. So I had to ride forward until I see a U-turn signal. I turned and kept riding, then I
noticed the crossroad sign and check my map. I saw that I had to turn left. But the red traffic light was
on, and I had to wait for 60 seconds. I turned left and I got stuck in a traffic jam. I waited there for
nearly 15 minutes. There was a car accident there, a car hit a motorbike and ran. At that time the
motorcyclist was moved to the hospital. I could keep my riding. Unfortunately, my phone was out of
charge,so I could not check my map and had to ask people there for route. After one hour and 02
times of getting lost, I finally reached my friend’s home. It is unbelievable.

2.TRAFFIC JAM
For many years, Daniel has been driving to work and back home every weekday. Every morning,
on his way to work, especially during rush hours, the highways are usually crowded causing traffic
jam. The situation is even worse in the evening when he drives home. If there is an accident or a car
has broken down and block the lane, most of drivers have to wait for hours or turn back to go on
another route. In the winter, especially when it snows, it is strongly for vehicles to move on thick
layer of snow. Many people have to leave their vehicles outside and walk home because they
completely cannot move. Daniel feels really tired when he is stuck in a traffic jam, so he usually
listens to music and waits until the end of traffic jam.

2. Watching television is an interesting and fun activity. The word television is often shortened to
TV. On TV you can watch many different programs about a wide range of things. Some examples of
TV programs are news,cartoons, reality shows, sports, documentaries and soap operas.
There are severalchannels which show different TV programs. In Vietnam, the main channels are
called “VTV1”, “VTV2”,and “VTV3”. TV guides tell us what programs are showing on which
channel, and at what time on a particular day.
Most programs on TV are episodes that are part of a series. These episodes usually last for about
30 minutes or full hour. At the weekend,there are lots of interesting movies on TV. Now you don’t
need to go to the cinema. You can watch films at home. It’s so comfortable.
You can learn a lot from watching TV but you should not watch too much or you will hurt your
eyes.

3. 5.CHRISTMAS IN AUSTRALIA
In Australia, the day before Christmas is hot. Christmas is during the summer months and it is the
beginning of a nice holiday time for pupils. Families which have relatives in Europe, dream of having
a traditional white Christmas once in their lives. Children would like to build a snowman or go skiing,
as they know it from the pictures, Christmas stories and Christmas cards.
In Australia, Christmas presents are distributed in the morning 25th of December. It is called
Christmas morning. The electric candles burn on the Christmas tree,the family sings Christmas carols
and unwraps their presents.
After that, children go outside or down to the beach because it is usually very hot — about 35
degrees C. At the same time, the rest of the family prepares Christmas lunch. Some families have a
big meal outside in the garden, others have it inside the house because it is cooler there.

6.OUR EASTER
Hello! My name is Jack. I am 12 years old and I live in a small town in the South of Britain with
my mum, dad and my sister Emily.
It is spring now and I am very happy because Easter is coming. I am telling you what we do in
Britain at Easter.
Easter starts on Good Friday in Britain. My mum makes hot cross buns and we eat them with tea.
We usually have some activities to celebrate Easter. Last year we made colorful hats. This year we
are going to design a basket full of painted Easter eggs. It will be a great fun.
On Easter Sunday morning, we have a big breakfast. After breakfast we all go to church. When
we get home, we give each other chocolate eggs. Kids get the biggest eggs. Then we play “Easter Egg
Hunt”. My parents hide some Easter eggs in the garden and Emily and I look for them. We love
playing it.
In the afternoon, my aunt and uncle come to our house to enjoy tea. We have Easter cupcakes and
delicious tea. After that we usually go for a walk together.
I like Easter because it is a great family festival, and we do not have to go to school for 02 weeks.
