Корова велика домашня тварина .Це білий з темними плямами. Корови їдять рослини. Маленька корова - теля, п'є молоко у мами. У корови є багато молока, бо вона їсть соковиту траву влітку і взимку сіно. Головна корова дає молоко, з якого потім роблять масло, сир, сир і сметану. І вона дає нам м'ясо. Корова це корисна тварина!

Hi, Emily! 

Hi, Jane! 

What's the news? 

I bought a new phone. It's amazing. It's got a very good media player and access to Internet. 

Wow, that's cool. But even though we use our phones every day, I prefer computers. 

Why? 

However good a phone's media player is, the computer's one is always better. And it's got a huge screen. 

But you can't always take it with you. For example, if you need to go on a vacation, you can't take a huge computer with you, but you always take a phone. And plus, it's got a camera, which also is always with you! Isn't it awesome? 

Well, yes. But in case you need to print something or use a program to do something, a computer is the way to. 

You're right, too. I guess both a computer and a phone have got their goods.
