2 . Nowadays medical technology seems to be advanced enough for doctors to perform brain transplants (移植). Though this procedure (程序) 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 adults 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 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, sex, 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 operation are that it should not be done on humans until doctors have overcome all the problems and challenges that stand in their way of making human brain transplants successful.

5 . Jack was 11 months old in the spring of 2015 when his parents, Erika and Christopher, recognized his development was not progressing as it should. The feeling was familiar to the couple. Just a few months earlier, Jack’s brother Chase, who is 16 months older, had been diagnosed with autism(自闭症) after he did not reach motion and language standards as expected.
Jack’s behaviors were similarly delayed, and his parents moved quickly to seek help. Today, Jack is 5 — he celebrated his birthday on May 13 — and he can speak in full sentences and read. After two years at a preschool that specializes in services for children with developmental disabilities, he will start kindergarten in the Smithtown school district in September. “Our family’s experience is a good example of the power and effectiveness of early intervention. The services our boys have received made all the difference,” the parents said.
According to scientists, autism can be detected at 18 months or younger, and by age 2 a diagnosis can be considered “very reliable.” The parents said they were happy with Chase’s success at the learning center, but still had concerns for Jack because he was not speaking. Developing social and communication skills can be among the greatest challenge for individuals with autism, even if they are able to say a few words early on. “We didn’t know if he was ever going to talk,” Erika said. “That was my biggest fear. We just didn’t know.”
Looking ahead, the parents are cautiously optimistic about Jack’s next educational move. He doesn’t handle change well, they said, and he likes to know his routine. Still, they expressed confidence that his time at the learning center has given him the skills he needs to be successful.

6 . Zhang Ying, 23, could have been a news host after four years studying broadcasting and talk show hosting at the university. So could Du Xintong. Instead of just becoming talking heads on TV, they decided to use their knowledge to help millions of children with speech disorder to find their own voices. They co-founded Voice Changer,which offers language rehabilitation(复原)for teenagers in China through online and in-person service platforms.
According to Zhang, each child needs to finish at least one three-month course, which consists of three 40-minute sessions a week. The length of the overall training program is dependent on each child's condition upon their evaluation.
“When we are teaching in-person courses, the parents cannot accompany their children. The children may feel a bit nervous in a strange environment, but they soon get used to it and start to enjoy the training,” she says.
They also launched a mini program on WeChat that provides online services for families of children with speech disorders-parents can upload their child's information and recordings to the self-testing tool and get a report. As well as online speech therapy(治疗),there are also online courses for parents,including guidance for speech therapy at home.
“We insist that parents should accompany their children when taking online courses as they need to play the role of both teaching assistant and desk mate,” she says.
There are only 10. 000 speech therapists in China, many of whom are not full-time. Unlike common volunteer work, to be a speech therapist volunteer, complex training is required before services can be offered.
“Speech therapy is a complex subject which requires knowledge, including training in education, psychology, linguistics and so on,” Zhang says, adding that their team has developed a training system for the volunteers to grow into professional speech therapists. They prefer to employ college students majoring in related subjects. such as broadcasting, linguistics, Chinese languages and literature or special education.

7 . People who have kids live longer than those who remain childless, an academic study has suggested. Researchers believe it is because adults’ immune systems are “refreshed” when kids go to nursery and start picking up infections.
During the course of someone’s life, their immune system can become weaker. But when kids start bringing infections home, their parents’ immune systems get a workout. Non-parents — unless they are teachers or nurses perhaps — do not get the same exposure to infection.
Writing in the journal Scientific Reports, Miguel Portela said parents had less risk of dying from infection than non-parents and if they did, it was about five years later. He said that “a parent’s immune system is refreshed by a child’s infections at a time when their own protection starts wearing thin.” He added, “With this improved immune system, the parent has a better chance to defend whatever infections that might strike when old and weak and parenthood is rewarded in individual terms through an improved immunization against infections.” Naturally there are other reasons why some people live longer than others, but they may not be comparable with becoming a parent. The academics say that high income and house ownership are always associated with higher survival but less so than having children.
Mr. Portela admits the research is far from complete, saying that while the results “record a relationship between the presence of children and death rate, the specific transmission mechanisms remain unclear. He acknowledges the presence of other, perhaps behavioral factors in parents which result in changed death rate compared to individuals without children.” He adds, “While the relationships of lifestyle choices such as smoking, obesity, drinking and other behavioral factors with life expectancy and causes of death are well studied and understood, the same cannot be said for the individual decision to become a parent”.
