5 Scientists often see the first ten years of a child’s life as the “window of opportunity.” 小题1: And studies show that the following activities can benefit their brain greatly. 小题2: Free playtime has always been an important part of “being a kid”, but it is also important to a child’s development. “Free play” not only helps kids develop different skills, it also helps them develop into happy healthy adults in the future. Read with kids Reading has long been known to improve children’s intelligence. 小题3: For parents who don’t have much time, just surrounding your kids with books goes a long way too. Put kids to bed early 小题4: Preschool children should get at least eleven hours of sleep and kids up to age 12 should try to get at least ten hours of sleep. Learn a second language Early studies in this field have shown that bilingual (双语的) kids can perform better under pressure. Young children can learn new languages with nearly perfect fluency (流利) and pronunciation. Praise good effort not intelligence. Your kids may be smart but you should mainly praise the effort they put into tasks. Kids, who are praised on intelligence, often feel it is a fixed quality, and mistakes or failures badly hurt their self-confidence. Kids who are praised on effort often focus more on learning. 小题5: A．Play some helpful games. B．Give them enough playtime. C．And they are not afraid to fail and try again. D．Kids still need time away from the TV to do homework. E. Kids who read often develop earlier writing and number skills as well. F. Everything at this time is very important to the development of a person’s brain. G. Studies show that kids with regular bedtimes are better at languages, math and reading.
