请大家看看我的这篇英语作文有什么错误，谢谢，有错误的请帮忙指正。

Last weekend, my parents and I go to the zoo. The zoo is so big, beautiful! Here are two panda. They are so lovely. All the pandas like to eat bamboo. Since then, I see three monkeys. They can be very naughty. They like the banana. Maybe they think bananas are delicious. Then, I saw an elephant. It's too big. I like elephants, because they are very cute, too. Finally, I see a lot of birds. They like to eat bread crumbs. I took pictures of them. This is a small travel I. I really enjoyed myself.
上周末，我和父母一起去动物园。动物园是那么大，看美丽的！这里有两个熊猫。他们是那么可爱。所有的大熊猫喜欢吃竹子。此后，我看见三只猴子。它们也很顽皮。他们最喜欢香蕉。也许他们认为香蕉是美味的。然后，我看到一头大象。它太大了。我喜欢大象，因为它们很可爱，太。最后，我看到许多鸟。他们喜欢吃的面包屑。我把他们的照片。这是我的一个小小的旅行。我真是太高兴了！
这个和你的意思一样，你可以借鉴

They like bananas best. ---------Their favorite food is banana.
I see a elephant -------------I see an elephant.
I like elephants,because they are cute ,too.----------I like elephants, because they are also very cute.
还有就是文中的so，比如The zoo is so big均可以换为very,变为the zoo is very big会好一点。

I see a elephant
a改为an （elephant中的e发的是元音）

It's too big.改为It's very big（too表示程度有点过头了）
This is my a little trip可以改为This is a little trip of mine（语法问题）

.It's too big.为it's big too.
