On a snowy winter night，a bus with 45passenger had an accident because of the wet road．And all of them were trapping in the bus and what was worse，the bus ran out of gas and it is very cold in it．They could do nothing but to wait for help．A man who lived nearby saw what happened．He and some villagers managed to open the door and helped all of them out of bus．He took them to his home but offered food and water and even some warm clothes to the children．They spent two days in their home and finally helps came．All of them were thankful with his help．

14．One of the first questions young children ask is"Why？"It is human nature to want （41）to find （find） out why things are the way they are．You can find out"Why"by turning the question into a hypothesis （假设） for（42）an experiment．
（43）For example，suppose you have been trying to grow tomato plants，but insects keep destroying （44）them．Someone tells you that（45）putting （put） large strips of colored cloth around the plants will keep insects away．（46）Your（you ）question might be"Do certain colours of cloth keep insects（47）away？"Then you'd begin your experiment．The first step would be to place different-colored strips of cloth around all of the plants except one．Then，as regular intervals，you would observe and record and note（48）whether the plant had any insect damage or not．
This experiment may prove that the answer to your question is"No，it is not different-colored strips of cloth （49）thatkeep away insects．"Or you may find that answer is"Yes，certain insects are kept away by blue cloth，but not yellow cloth．"…（50）Whatever you have found，you are well on your way to understanding how you can use scientific thinking to solve a problem in you own life．

13．Every country shares things （46）incommon：we value family and laughter，cherish food and health，and celebrate large （47）festivals （festival） and traditions．Yet within the similar things we share，there are unique parts of each country．One of characteristics that are famous of British people（48）is （be） their sense of humor，particularly self-mockery （自嘲）．This is a type of humor that criticizes and undervalues oneself．For example，a fat person may joke："I am on a new sea food diet．If I see food，I eat it．"This is（49）awell-known self-mockery joke．It's difficult why self-mockery（50）is tied （tie） to the British people．But every nation's sense of humor comes from its culture and history．It could come from another British characteristic，modesty，（51）meaning （mean） not talking openly about your skills．This seems to be something that is similar to people in China，（52）wheremodesty plays a big part in daily life．It also acts as a defense of our self-respect by playing down our skills，this can（53）lessen （less） the chance of people criticizing us．Another possible reason is（54）thatthe British people do not take themselves too（55）seriously （serious）．

12．Childhood obesity（41）is considered（consider） one of the most serious health challenges of the 21st century．Obesity can（42）harm（harmful） nearly every organ in a child's body---heart and lungs，muscles and bones，kidneys as well as the hormones（荷尔蒙）（43）that/whichcontrol blood sugar and puberty（青春期）．What's worse，young people who are overweight or obese are likely to remain so even when they grow into adulthood，（44）increasing（increase）the risk of developing disease and disability later in life．
Globally，an（45）estimated（estimate） 43million preschool children under the age of 5were overweight or obesity in 2010，a 60% increase since 1990．The problem affects countries rich and poor，and places the greatest burden（46）onthe poorest：of the world's 43million overweight and obese preschoolers，35million live in developing countries．By 2020，if the current epidemic（盛行） continues，9% of all preschoolers will be overweight or obese---nearly 60million children．
Obesity rates are higher in adults（47）thanin children．But in relative terms，the U．S．，Brazil，China，and other countries have seen the problem arise more（48）rapidly（rapid） in children than in adults．
Of course，some regions still struggle hard with child（49）hunger（hungry），such as Southeast Asia and Africa．But globalization has made（50）theworld wealthier，and wealth and weight are linked．
