某粮食仓库在11月1日至11月10日的时间内运进粮食情况如下：（运进记为“+”，运出记为“-”）+1050吨，-500吨，+2300吨
-80吨，-150吨，-320吨，+600吨，-360吨，+500吨，-210吨，在11月1日前仓库内没有粮食．
（1）问哪一天仓库的粮食最多，是多少？
（2）11月10日，仓库内共有粮食多少吨？
（3）若每吨运费10元，从11月1日到11月10日仓库需付运费多少元？
（1）11月1日：1050吨；11月2日：550吨；11月3日：2850吨；11月4日：2770吨；11月5日：2620吨；
11月6日：2300吨；11月7日：2900吨；11月8日：2540吨；11月9日：3040吨；11月10日：2830吨；
故可得11月9日的粮食最多，3040吨．
（2）11月10日，仓库内共有粮食2830吨；
（3）所运粮食总量=1050+500+2300+80+150+320+600+360+500+210=6070吨，
故运费为6070×10=60700元．

| Two runners stand side by side at the starting line of a race. Both look very strong and fast. 1 one runner speeds ahead and wins the race. The other falls behind. Some athletes can reach great 2 such as the achievement of an Olympic gold medal. Others never live up to their 3 . What kind of 4 before a race or another event makes the 5 ? Everyone knows that athletes work out to strengthen their 6 . But research shows that strengthening the mind may be just as 7 . Careful study indicates that the best athletes win 8 because they think they can win. Thinking positive thoughts seems to give possibility for 9 in sports. People who say "I know I can do this" to themselves over and over often find they have the 10 to win. On the other hand, people who think "I can't win" often 11 . One procedure that helps many athletes is creating 12 in the mind. They are told to think of each 13 they must make to win. Some use pictures that are more fanciful (富于幻想的). One skater liked to 14 a star bursting inside her, 15 her with energy. Another athlete who wanted to feel 16 pictured himself as a 17 floating in the air. Next time you want to do something well, try training your 18 to help you. Perhaps a teacher or another instructor can help you plan your training. If you imagine yourself doing better, you may soon see 19 in what you 20 can do. Positive thinking and pictures created in your mind can help you win! | ||||
