[填空题]Inspiration for Your Kids
A parent, or anyone else who interacts regularly with kids, knows that communicating effectively with them can be difficult. If you want children to grow up into the best possible versions of themselves, it’s crucial to replace damaging words in your vocabulary with alternatives that help build character. Some of the things parents say to kids seem harmless or even constructive on the surface, but, experts say, they may hurt more than help. Here are some aspects under our consideration.
1. When the kid deserves praise
For years, we’ve been told that boosting a child’s self-esteem is important to his or her success in life. But child experts are now learning that too much praise can backfire (事与愿违).

The implication of saying "You’re the p

Health Education{{/B}}
Health education is the part
of health care that is concerned with promoting healthy behavior. A person’s
behavior may be the main cause of a health problem, but it can also be the main
solution. This is true for the teenager who smokes, the mother with the poorly
nourished (营养) child, and the butcher (屠夫) who gets a cut on his finger. By
changing their behavior these individuals can solve and prevent many of their
own problems.
Health education does not replace other health
services, but it is needed to promote the proper sue of these services. One
example of this is immunization(免疫): scientists have made many vaccines (疫苗) to
prevent diseases, but this achievement is of no value unless people go to
receive immunization.
