Nowadays medical technology seems to be advanced enough for doctors to perform brain transplants (移植). Though this procedure has only been successfully performed on animals so far, doctors are still hoping to perform this procedure on humans. However, in my opinion, brain transplants should not be performed at all, especially not on humans because of the large number of problems and side effects that could come along with. Hopefully these dangerous side effects will convince doctors not to perform this procedure on humans.
Despite many benefits technology brings, I do not think this medical technology of brain transplants will help. We were all born with one brain and through childhood to adolescence our mind developed into who we are, so if with a different brain we would no longer be unique. A person with a different brain would seem to be a total stranger and in many ways they would be. No one should steal our identity from us, even if we are seriously injured, and change it to a completely new one. Also for the people who have died with healthy brains, that was their identity and it should not be given to anyone else.
Another problem with brain transplants is how doctors can choose what are “healthy” or “normal” brains. An elderly person who has died would have an aged brain that would not be as efficient as a younger person’s brain. Then would doctors have to find healthy brains of the same age as the person who needs it? This could also bring up other factors such as intelligence, gender, or physical problems that a person might have had before death. Also another problem might be how long a brain can be kept “alive” after death and how it can be kept “alive” without damage.
Overall, my feelings about this surgery are that it should not be done on humans until doctors have overcome all the problems and obstacles (障碍) that stand in their way of making human brain transplants successful.

A.People shouldn’t give their healthy brains to others.
B.Having a brain transplant means losing one’s identity.
C.Transplanting brains is changing old brains into new ones.
D.Having brain transplants indicates stealing identity from others.
3.What do we know about “healthy” brains?

Nowadays, we depend on advanced technology too much. However, a the saying goes, a coin has two sides. The tool bringing you convenience may also put you in trouble. Here is a modern-day horror story:
A young mother was employed in doing her writing when her son, aged 2, burst into tears somehow. She did all she could to ease her son. But in vain. She had no way to comfort him. Meanwhile, her iPhone rang aloud, which attracted his son's attention. He stopped crying temporarily. It occurred to her that the iPhone might help. Thus, she handed her iPhone to her son: What happened next? The child entered an incorrect passcode on his mother's phone so many times that the device became locked for 251 14984 minutes, about 47 years, making it absolutely useless to its formerly digitally connected owner. That's the scene now facing a Shanghai mother, identified only as Ms Lu by Chinese news reports, whose kid played with her phone and unfortunately began the process of disabling the device for, basically, forever. According to a news report, Ms Lu waited two months to see if the situation would improve, but the iPhone remained locked. “I couldn't really wait 47 years and tell my grandchild it was his father's mistake, ”she reportedly said. The alternative mode of accessing the phone is to wipe it with a factory reset. This is why you should always backup ( 备份) all your data.
iPhone can become locked with six failed attempts at entering a passcode on the locked screen, and the amount of time for which the phone is locked can compound (增加) with ongoing attempts to break in. So, for all the parents out there: see to it that you don't let your kid loose on your phone, assuming you want to still use it when he's done, of course.
1.Why did the young mother hand her phone to her son?
A.To focus on her housework. B.To comfort her crying kid.
C.To let him answer the phone. D.To play the phone with him.
2.What happened to Ms Lu?
A.The system of her iPhone broke down.
B.She couldn't use her iPhone back then.
C.Her iPhone was locked for two months.
D.She forgot the passcode of her iPhone.
3.To solve her problem, Ms Lu should____
A.backup all the data immediately
B.wipe the iPhone with a factory reset
C.enter the correct passcode for six, times
D.set a new passcode to unlock the iPhone
4.What does the underlined part in the last paragraph mean?
A.Don't hand your own phone to your young kid.
B.Let your kid feel loose when using your phone.
C.Make sure to set a passcode to lock your phone.
D.Be careful when your kid plays with your phone.
