Others will unconsciously push you in a direction that they see as best. {#blank#}4{#/blank#}. Just don't let criticism （even the constructing type） destroy your creativity during the creative process.

How to escape from a car in water

    "If you get on your phone and call your parents or your sister, or 911, you will die," says Robert May, a 21-year-old veteran(老兵) of the Indiana State. No one else will arrive in time: you have to save yourself.

    Move quickly. Minivans(微型货车) might float for as long as10 minutes. {#blank#}1{#/blank#} In a study from the University of Manitoba, three passengers were able to exist with a child mannequin(人体模型) through a single driver-side window in just 3 seconds.

    Unbuckle(揭开)your seat belt, lower your window and climb out, ideally onto the roof of the vehicle. {#blank#}2{#/blank#}Unfasten them from the backseat, pull them into the front and push them out of your window, oldest ones first. In May's experience, electric car windows will continue to work after falling into water. {#blank#}3{#/blank#}

    Don't open the door, water will flood in. Once full of water, the vehicle will sink fast. {#blank#}4{#/blank#}Vehicle submersions (淹没) have one of the highest death rates of any type of single-motor-vehicle incidents, responsible for 400 deaths a year in North America.

    After you get on top of your car, figure out if it makes sense to stay put or swim for dry ground. {#blank#}5{#/blank#}Just get out first, May says.

    {#blank#}2{#/blank#}. You do not need to pack tons of toys, sweets and a tablet full of games in order to keep your little ones entertained. You can encourage them to create a travel journal or smash book, read, tell each other stories, or give them a camera to capture the most precious moments during your trip. {#blank#}3{#/blank#}.

    {#blank#}4{#/blank#}. This is a must even during the shortest road trip. You can handle a headache, but your child can't. If you do not know what to put in your first aid kit (急救箱), consult your children's doctor, because all children are different and the medicines either.

    Apart from the above, money, passport, avoiding heavy luggage, pick a family­friendly destination and family friendly accommodation are also needed.
