理解血管及心脏的结构，完成下列各题： （1）若B为左边心脏，则A流______

What do you think our life will be like in 2050? Some people are talking about it on QQ.

Blue Sky	I think there won’t be any TV channels (频道) in 2050. People will be able to choose (选择) a programme from a “menu” and a computer will send the programme to the television. In 2050, we will be able to feel the things we see on TV with our hands.
Julia	In 2050, there won’t be enough water. Some places will be drier and people will not be able to have enough food. There may be serious water shortage (缺乏).
Ashley	Don’t be so pessimistic about that, Julia! People will solve this problem. And I think there will be less water pollution. Water will be much cleaner than it is now.
Linkin	I quite agree with Ashley. And I believe in 2050 doctors will be able to help blind and deaf people see and hear again. All people will be healthy because they will take a kind of special medicine when they are born.
