Seventeen-year-old Mike O'Donnell has been big success in high school. He seemingly has it all, when, right before the championship basketball game, his girlfriend Scarlet Porter finds out that she is pregnant. In that moment, he makes the decision to throw everything away (including basketball and a chance at a scholarship) and proposes to her.
Twenty years later, Mike's life has come to a standstill. Scarlet has separated from him, forcing him to move in with his geeky and wealthy best friend since high school, Ned Gold. His job is going nowhere, and his kids Maggie and Alex want nothing to do with him. While visiting Hayden High School to reminisce about the life he threw away, he encounters a mysterious janitor. On the way home, he sees the janitor standing on the edge of a bridge - apparently about to commit suicide, Mike runs towards him, but his path is blocked momentarily by a passing truck. When he reaches the edge, the janitor is gone, and there is a strange vortex below the bridge. Mike slips and falls into the vortex, blacks out, and awakens back on the bridge. When he gets home, he discovers that he has been magically transformed into his 17-year old self.
Ned sees Mike in his house, and thinks he is a thief. Ned fights with Mike, as Mike tries to prove he is the real Mike. When Ned tries to hit Mike over the head with a picture of the two of them at their 1989 graduation, he realizes that is the real Mike. Mike then returns to the school to find the janitor that he spoke with the day before and became aware of there being no such person working there. Mike then decides that with Ned posing as his father, Mike enrolls at Hayden High as "Mark Gold". He believes he has been given the chance to live his life over again, "but to do it right". Then he discovers that Maggie is dating the basketball captain Stan, who is bullying Alex. He realizes that his real mission is to help his children, and makes friends with both Alex and Maggie. With "Mark"'s help, Alex gets a place on the basketball team and the girlfriend he desires. "Mark" comforts Maggie when she is dumped by Stan, who was pressuring her for sex. "Mark" also meets Scarlet. He helps her decorate her garden, gaining a new appreciation for her, and dances with her before she goes on a date (to the song that he and Scarlet danced to at their wedding). "Mark" and Scarlet clearly feel a connection as they danced, and are about to kiss, until Alex walks in on them. At first Scarlet seemed uncaring that her son is right there, but then she feels embarrassed and tells "Mark" that she is Alex's mother and that this is inappropriate.
With "Mark's" help during the basketball game, Alex makes the winning basket. Meanwhile, Ned is attracted to the principal of Hayden High, Jane Masterson. Although his initial attempts to 'peacock' her fail he manages to take her out to dinner. When "Mark" notices the two of them leaving he decides to throw a party at "Ned's" house to celebrate Alex scoring the winning basket and to help him get the girl he likes. During the party Scarlet appears, looking for Alex, and "Mark" tells her that Alex could have a girlfriend by the end of the party and brings her up to the balcony to show her. Ned and Jane soon bond over a love of The Lord Of The Rings. When he takes her back to his house, they discover an out-of-control party raging there. After Maggie tries to have sex with "Mark" Maggie sees Ned and goes looking for "Mark" to warn him and finds Mark with her mother Scarlet. While "Mark" and Scarlet are talking, Mike's feelings for her are reawakened, (especially after she tells him "he's really become a part of the family"). But when he kisses her, she is appalled, and slaps him and calls him a "weirdo little man child" when he chases after her and tries to tell her that he is Mike. This exchange is witnessed by Maggie and her friends, who are all disgusted and slap him too, especially since Maggie has become smitten with "Mark". For cutting his date with Jane short, Ned slaps "Mark" a few times as well.
The following morning, Ned reminds Mike that it is the date of his divorce hearing with Scarlet. "Mark" appears in court to read a letter from Mike O'Donnell pleading for a second chance. Scarlet is touched by the letter. When she sees that the "letter" is really just a piece of paper with directions on it, she realizes that "Mark" spoke extemporaneously. Later, at the championship game, Mike makes a gesture which she recognizes as his. Realizing the truth about who "Mark" is, and that she is in the same situation as twenty years earlier, she flees the scene. Mike follows, handing the ball to Alex, who goes on to make the winning shot. The janitor catches sight of Mike and changes him back into his adult self. Mike promises Scarlet to spend the rest of his life making it up to her. Scarlet and Mike kiss and reunite.
In the end, Mike happily reconciles with his family, and becomes the coach of the Hayden High basketball team, while Ned and Ms. Masterson seem to have a "relationship".
如何洗衣服？也许有人会说，衣服谁不会洗啊？放到水里，加点洗衣粉洗就成了呗。是啊，说是这样说，可是洗衣服还有不少学问呢。我就说说我的“洗衣经”吧。 说起洗衣服，想想真有不少要说的呢。 首先要分开洗。内衣外衣、深色浅色要分开。个人和个人的衣物也尽量分开洗涤，这样可以防止不同人体间细菌和病菌的相互交叉感染，尤其是宿舍或者朋友的衣服尽量不要放置在一起洗。即使是自己的衣服，内衣和外衣也要分开洗。因为外衣接触外界的污染和尘土较多，而内衣将直接接触皮肤，为避免外界尘螨等对皮肤的不良入侵，内外分开洗涤是有科学道理的。不同颜色的衣物要分开洗涤，可将颜色相近的一同洗涤，浅色的一起洗涤，容易掉色的单独洗涤，避免衣物因脱色而损坏。另外，袜子和其他衣物不要一起洗涤。 其次，使用洗衣粉宜提浸泡一会。洗衣粉功效的发挥不同于肥皂，只有衣物适时浸泡才能发挥最大的洗涤效果。浸泡时间也不宜太长，一般20分钟左右。时间太长，洗涤效果也不好，而且衣物易褶皱。有人洗衣服时把洗衣粉直接撒在衣物上便开始搓揉洗涤，那样不能发挥最好的洗涤效果，对洗衣粉是一种浪费，当然，免浸泡洗衣粉出外。另外，冬季一般宜使用温水浸泡衣物。水温过低，不能有效发挥洗衣粉的洗涤效果，水温太高，会破坏洗衣粉中的活性成分，也不利于洗涤。 再次，衣物及时更换，及时洗涤。衣服要及时更换，相信道理大家应该都很清楚。可是，衣物换下后应该及时清洗，有人却做的不好。好多家庭喜欢将换的衣服积攒起来，每周洗一次，这样很不科学，容易使衣物上积聚的细菌大量繁殖，容易诱发皮疹或皮肤瘙痒症状。为了个人和家人的身体健康，还是勤快一点，把及时换下的衣物及时洗涤，这样，其实也费不了多少时间，也不至于最后要花费半天甚至更长 的时间专门来洗涤大量的衣物要节约的多。另外衣服穿的太久就比较脏，要花很大的力气洗涤才能洗干净，也容易将衣物搓揉变形，而影响美观和穿着效果。 洗衣服是个简单的小家务，也是生活中不可缺少的一件事，学问却很多，也许您的“洗衣心得”比这还要科学，还要多样，欢迎您 的指正~~
第一步：教育引导 不同年龄阶段的孩子“吮指癖”的原因不尽相同，但于力认为，如果没有什么异常的症状，应该以教育引导为首要方式，并注意经常帮孩子洗手，以防细菌入侵引起胃肠道感染。 第二步：转移注意力 比起严厉指责、打骂，转移注意力是一种明智的做法。比如，多让孩子进行动手游戏，让他双手都不得闲，或者用其他的玩具吸引他，还可以多带孩子出去游玩，让他在五彩缤纷的世界里获得知识，增长见识，逐渐忘记原来的坏习惯。对于小婴儿，还可以做个小布手套，或者用纱布缠住手指，直接防止他吃手。但是，不主张给孩子手指上“涂味”，比如黄连水、辣椒水等，以免影响孩子的胃口，黄连有清热解毒的功效，吃多了还可导致腹泻、呕吐。
