When I was a kindergarten student, I went to a village which was the living place of my best friend's grandfather's house. It was in a remote area and the natural scenery I saw there was the most beautiful natural scenery I have ever seen. It was in (...nói tên địa điểm ra nhé!...) and the small river, the hill, the green fields and the blue sky made a combination that I felt something out of the world. I saw it in one autumn evening when I went to explore the surroundings of the village. That was an awe-inspiring scenery that I will never forget. I saw this scenic beauty in 2011 and it was mid-autumn season then.

My friend, I and one of my friend's cousin were present at that time and I heard from my friend that his village was a very beautiful place. I could not believe how much beautiful it was until I saw it with my own eyes.

We left for the river in the evening and I was amazed to notice the hill and the sloping road track beside it. The river was flowing gently and the vast paddy fields were all around us. I heard the chattering of the birds in the green trees and the sound was creating a harmony in my ears.

To me, this was a truly amazing feeling to witness a natural scenery that could exist only in our imagination. I have seen many rivers, hills and paddy fields but in my friend's village, they were arranged in such a way which is only possible in an artist's picture. The blue sky seemed very nearer to the horizon and the vast green all around us make me feel like visiting in a fairy land.

Some neighbors are good while some are bad. My neighbors are good.

The Lim family lives next door on our right. Mr. Lim is a post-master and Mrs. Lim is a housewife. They have two adorable children: a boy and a pretty girl. Mr. Lim is a very helpful man. He helps to pay our telephone bills for us. Whenever we have any letters or parcels to post, we give to Mr. Lim and he posts it for us. Mrs. Lim takes great pride in her garden. She grows all kinds of plants. Her garden is always full of bright colored flowers. She helps me with my garden. She has taught me a lot of things about gardening. She is a good cook and loves baking delicious cakes for her family and neighbors. The Lims are friendly, helpful and honest people.

The neighbors who live on our left are Mr. and Mrs. Rao. Mr. Rao is a businessman. He deals in carpets, and owns a big carpet shop. Mrs. Rao is a school-teacher. They have no children. Mr. Rao is rarely at home. He is always away on business trips. We only see him on Sundays. Mrs. Rao loves children. She used to buy sweets and chocolates for the children in the neighborhood. On every Deepavalli eve, the Raos hold a children’s party. All the children in the neighborhood are invited. We enjoy going to the party. All kinds of cakes, sweets and ice-creams are served. At the end of the party, presents are given to all the children.

I like my neighbors. I feel very fortunate to have such good neighbors.

My new school is called Ly Tu Trong Secondary School - the school is named after the national hero Ly Tu Trong. My school is a high quality focal point of the district, always at the forefront of all movements, regardless of learning or art - Physical education. The school's facilities are always available to help students live and study in the most comfortable environment. The teachers are always enthusiastic, responsible and the typical teachers in the district. The school's students are always ranked well and 100% of the students pass the public school system. My school is a very good environment for students to study and live well. In subsequent years, the school can strive further.

a) | x-3 | -1 > hoặc bằng 0

1+| x-3 | - 1 > hoặc bằng 0 +1

1+| x-3 | - 1 > hoặc bằng 1

Dấu = xảy ra khi x-3-1 =0

                            x =0+1

                         x-3  =1

                             x=1+3

                              x=4

b) | x-2 | +3 < hoặc bằng 4

1+| x-2 | +3 < hoặc bằng 4+1

1+ |x-2 | +3 < hoặc bằng 5

Dấu = xảy ra khi x-2 +3 =4

                            x -2 = 4-3

                            x -2 = 1

                                 x = 1+2

                                 x = 3

c) 2< |x| <5

Vì |x|>2 và |x| <5 

nên |x|= 3 , 4

Suy ra x=3,-3,4,-4

Vậy x { 3, -3, 4 ,-4 }

Dear Jake,
How are you today?

Now I’m writing to tell you about my new neighbours that have moved recently to next door house. In the very first day, I met two sisters aged about 17 and 21. They looked very cheerful and funny. After having a small talk, they invited me for a dinner. I made an apple pie and took it to them. There I met their mother who is a teacher in the kindergarten and their father who is a web designer. We spent a very good time, girls were singing and mother accompanied them on piano. I enjoyed it very much.
But still I really miss my previous neighbours - Rodriguez family. It was a big family with lots of kids, They have been living here for almost 20 years and had to move to a bigger house. They always invited me to family parties, holidays and barbeque, because of this I felt as a member of their family and also was pleased their kind behaviour to me. I will miss them extremely.
Anyway, I’m glad that The Rodriguez now live in a big bright house and my new neighbours are such interesting and cheerful.
What about your news?
All the best,
Anna

Last May Day my class went to the countryside by bus for our holiday . There was too much trafficon the road so we had to move very slowly . It took us about one hour to get out of the town . After some time , we came to a hill . It was green and beautiful. We thought this was a good place for a picnic , so we stopped and took the food , fruit and drinks out of the bus . We sat down and began to eat . Studdenly a strong wind blew and soon it started to rain . We had to run back to the bus and have our meal in the bus . Then we drove back home . What a sad trip !
