4.光电计时器是一种研究物体运动的常见仪器，当有物体从光电门通过时，光电计时器就可以显示物体的挡光时间．如图所示，PQ是一端带有滑轮的长木板，1、2是固定在木板上的两个光电门(与之连接的两个光电计时器没有画出)，小车上固定着用于挡光的窄片K，测得其宽度为d.让小车从木板的顶端滑下，光电门各自连接的计时器显示窄片K的挡光时间分别为t1和t2.为了计算出小车匀变速直线运动的加速度，除了测量d、t1和t2之外，还需要测量{#blank#}1{#/blank#}，若该测得的量用x表示，则加速度的表达式为a＝{#blank#}2{#/blank#}.
5.一深4 m的井中用水桶提水，出井口后再往上提了1 m，选井口处为原点，水桶竖直向上提升的路线为x轴，向上为正方向，则水桶在水面时的位置坐标为{#blank#}1{#/blank#}，最后水桶的位置坐标是{#blank#}2{#/blank#}．如果选水面为坐标原点，那么水桶在水面时的位置坐标为{#blank#}3{#/blank#}，最后水桶的位置坐标为{#blank#}4{#/blank#}．

Michelle Obama has launched her campaign against childhood obesity in the US，saying that it is a problem that concerns her both as the first lady and as a mother.
Mrs.Obama said that the campaign was designed to encourage people to live healthier lives，but admitted that she herself was not immune to the temptations of junk food.
“I love burgers and fries.And I love ice cream and cake.And so do most kids，” she said.But，she added，“We’re not talking about a lifestyle that excludes all that.”
“The question is how we help people balance their diet so that they’re not facing lifethreatening，preventable illnesses，but they’re enjoying their food，they’re eating their vegetables，they’re doing their running，walking and playing，and they still have time to get a good，fun meal every once in a while.”
One in three American children are overweight or obese，putting them at the higher risk of developing diabetes(糖尿病)，high blood pressure，high cholesterol(胆固醇) and other illnesses.
Billions of dollars are spent every year treating obesityrelated conditions.
“None of us wants this future for our kids，” Mrs.Obama said at the White House.
“We have to act，so let’s move.”
Her campaign has four parts：helping parents make better food choices，serving healthier food in school vending machines(自动售货机) and lunch menus，making healthy food more available and affordable，and encouraging children to exercise more.
The campaign，which Mrs.Obama starts，is aimed at solving the childhood obesity problem in a generation，so that children born today can reach adulthood at a healthy weight.
“This isn’t like a disease where we’re still waiting for the cure to be discovered.We know the cure for this，” she said at the opening ceremony.
President Barack Obama praised his wife for solving what he called one of “the most urgent health issues facing the country”．
“This has enormous promise in improving the health of our children，in giving support to parents to make the kinds of healthy choices that are often very difficult，” he said.
