A dialogue???

Sorry. Bây giờ mk đang hơi bận. Cần thì tối mk làm nốt cho 2 bài kia.

1. After a hard-working day, I usually watch TV to relax. My favourite programme is Discovery. It's on VTV7-a education channel. They do experiments and they teach us how to do some fun experiments at home. It's pretty fun learning and playing like this. I like this programme because it teaches me a lot about doing experiments. I learned that we can't just read books and believe every things they say. We have to do experiments to verify what we've learned on the paper.

Mình mong là đúng.

Hình như bạn nhầm nhọt sang trồng trọt rồi.

Those: Những cái kia (dạng số nhiều của that)

These: Những cái này (dạng số nhiều của this)

Topic của 3 unit đấy là gì ấy nhỉ?

Ta có \(\frac{a}{b}=\frac{c}{d}=\frac{ac}{bd}=\frac{a^2}{b^2}=\frac{c^2}{d^2}=\frac{a^2+c^2}{b^2+d^2}\)

Vậy \(\frac{ac}{bd}=\frac{a^2+c^2}{b^2+d^2}\)

Robots will be very useful in the future. It will be able to do almost everything. But it won't be able to do things like express feelings, or thinking. However, housework and heavy works like building a house will be done by robots. I don't think robots will be able to do works without human's control anyway. And maybe they can talk. That probably sentences which were programmed in it. Maybe it even don't understand what it says.
