    The book ABigFatCrisis: TheHiddenForcesBehindObesityEpidemic— andHowWeCanEndIt by Deborah Cohen, a senior natural scientist, is very popular now. ____ But according to this book, the following are some misunderstandings of obesity or being overweight.

1)．If you're obese, blame your genes.

    ____ Yet, between 1980 and 2000, the number of Americans who are obese has doubled—too quickly for genetic factors to be responsible. At restaurants, a dollar puts more calories on our plates than ever before, because restaurant meals usually have more calories than what we prepare at home, so people who eat out more frequently have higher rates of obesity than those who eat out less.

2)．If you're obese, you lack self­control.

    Research shows that if we are faced with too much information, we have a tendency to make poor choices on diet. ____ Even, the most vigilant(警觉的)people may not be good controllers of themselves.

3)．____

    Although the US Department of Agriculture estimates that fewer than 5 per cent of Americans live in the “food deserts”， about 65 per cent of the nation's population is obese. For most of us, obesity is not related to access to more fresh fruits and vegetables, but to the choices we make in supermarkets.

4)．The problem is not that we eat too much, but that we don't exercise.

    Michelle Obama's “Let's Move” campaign is based on the idea that if kids exercise more, childhood obesity rates will decrease. ____ In fact, although a drop in work­related physical activity may explain up to 100 fewer calories burned, leisure physical activity appears to have increased.

如图是某款电热水龙头的电路原理图．R₁、R₂为电热丝，通过旋转手柄可使扇形开关S同时接触两个相邻触点，实现冷水、温水、热水挡之间的切换．当开关同时接触2、3触点时，水龙头放出的是 ____水（选填“冷”、“温”“热”）．若R₂=2R₁，水龙头在温水挡正常工作时电功率为2000W，则它在热水挡正常工作1min消耗的电能为 ____J

古诗文默写。
①                ，江春入旧年。         （王湾《次北固山下》）
②塞下秋来风景异，           。    （范仲淹《渔家傲•秋思》）
③           ，吟鞭东指即天涯。       （龚自珍《己亥杂诗》）
④政通人和，                 。        （范仲淹《岳阳楼记》）
⑤      ，      。     ，     。（李商隐《夜雨寄北》）
⑥《白雪歌送武判官归京》中的“           ，           ”虽只字未提送别，笔端却饱含悠悠不尽之情思，达到了“此时无声胜有声”的艺术效果。
