1. __________ For me, every weekday begins the same: I get up at 7.00. I have breakfast, I take the bus to school, I go to lessons ... I don’t hate this daily routine, but it isn’t very thrilling. In the evenings, however, I drive Formula 1 cars, build enormous cities and defend my planet against aliens. In short, I play computer games. It’s like entering a different world. That’s why I love playing them so much.

2. __________My interest in computer games has taught me a lot about computer graphics. I want to study computing at college, and learn how to design and program games. Eventually, I’d like to start my own software company, creating and testing new games. That way, I could spend all day doing what I love most.

3. ____________Computer games are interesting because they often contain stories and characters. The games are getting better all the time, but they are also getting more expensive. The only thing I don’t like about my hobby is the cost! New games are often about $50.

4. ____________ Some of my friends from school are interested in computer games too. We normally meet at my house in the evenings and play for a few hours. We sometimes play at weekends, but if the weather’s good I prefer to go cycling or play basketball instead.

5. ____________ I first became interested in computer games about four years ago. I was staying with my cousin for the weekend. He had some games and he taught me how to play them. I became hooked immediately! When I got home, I decided to save all my money for buying games. Now I’ve got about twenty different games

tìm giá trị lớn nhất:
A = -x² +2xy-4y² +2x+10y+5

tìm giá trị nhỏ nhất:

A=\(\left(x^2+x+1\right)^2\)

số chia là 9

x : 9 = 4 dư 8

x = 9 x 4 + 8

x = 44
