A zoo is a place where animals and birds are kept in enclosures and taken care of so that people can visit them. It was only last week that we visited the zoological park in Gangtok as part of a school field trip. The atmosphere and experience were so memorable and breath-taking that we can’t wait to visit again! The most amazing part was that we got to see so many endangered species like the red panda and the Himalayan black bear. We got to see them so close and it is a shame how these animals are endangered. Only if one has such experiences can we understand the harm humans do to these animals, but a zoo is also an example how we can protect the few remaining.

Last Sunday, the weather was pleasant. I, along with my family, visited zoo. It is situated at a distance of twenty kilometers from our house. When we reached the gate of the zoo, there was huge crowd there. People were buying entrance tickets. Some of them were sharing their excitement about the visit of the zoo. We reached there at 11.30 a.m. We bought our tickets and went inside the zoo. There were a large number of people there.

We first visited zoological garden. There we saw a huge lake in which different types of water-birds were swimming. The sight of a white duck swimming on the smooth surface of clean water was a wonderful delight. Then we moved ahead to the enclosure where playing birds were chirping. They included sparrows, pigeons, eagles, parrots of different colours. Their enchanting music delighted us much.

There were wild animals like lions, tigers, leopards and tigresses in other enclosures. We were frightened at the roar of the lions. At the same time it was awesome to see the king of the forest. When someone moved near the enclosure, the majestic animal began to roar. Then we moved to the den of the tiger. Its flashing glare and sharp teeth filled us with fear. We also saw the elephants and bears. Then we came across a big garden in which stags and deers were frisking about. These animals were very active, sharp and smart. In one corner of the garden there was a big tree on which a large number of monkeys and baboons were jumping. Their tricks and pranks were very pleasing. Some people threw bananas at them to which they immediately tried to catch by jumping down the branches. Children were enjoying by making faces at them.

We next halted at an aquarium. There were varieties of aquatic animals and birds there. There were many species of fish. Their fidgeting in water was really very delighting. Next to this enclosure were kept polar bears who looked deserted and dejected.

tên của bn đẹp lắm 

k mk nha

b: Xét ΔDEF vuông tại D có DK là đường cao

nên \(DF^2=EF\cdot KF\)

a thì cộng số âm trc rồi cộng số dương sau

Thông báo! đề nghị các bạn sau đây phải cho nó vào tù

a, Theo định lí Pytago tam giác ABH vuông tại H

\(AH=\sqrt{AB^2-BH}=\sqrt{81-9}=6\sqrt{2}\)

Theo định lí Pytago tam giác AHC vuông tại H

\(HC=x=\sqrt{AC^2-AH^2}=7\)

b, Xét tam giác ABC vuông tại A, đường cao AH

* Áp dụng hệ thức : \(AC^2=HC.BC=1600\Rightarrow AC=x=40\)

Khó quá! Lạy ông đi qua lạy bà đi lại giúp mình zớiiii !!!

Bài 3:

a: Xét ΔABC có AE/AB=AF/AC

nên EF//BC và EF=1/2BC=7,5cm

\(AC=\sqrt{15^2-9^2}=12\left(cm\right)\)

S=1/2*9*12=54cm²

b: Xét ΔCAB có CF/CA=CH/CB

nên FH//AB và FH=AB/2

=>FH//AE và FH=AE

=>AEHF là hình bình hành

mà góc FAE=90 độ

nên AEHF là hình chữ nhật

1)4;5;6

3;5;7

2;5;8

1,5,9

0;5;10

Thank you bạn nha, miyano shiho
