第三部分
According to scientists, young people\’s taste buds are not ready for the bitter taste of some vegetables. Our taste buds develop as we get older, but young people prefer sweet food. In fact, most of us do, just like our prehistoric ancestors. They ate a lot of sweet fruit because it was widely available and easy to notice on trees and bushes, and it was a good source of energy. They also realised that they had to be exceptionally careful with plants that had a bitter taste, since they were often poisonous! Apart from bitter and sweet, what other tastes can we detect? You might be surprised to learn that our taste buds can only distinguish two more: salty and sour. When we reach early teens, we start to prefer sour things to sweet things. However, recent studies have shown that girls and boys experience taste in different ways. Girls have more sensitive taste buds and can differentiate flavours more easily, especially sweet and sour, while boys prefer stronger, more extreme flavours.

4.How does saliva help when we eat?
It transports the taste of the food to our taste buds．
解析：(文章第三段提到第一句中提到“when we eat it，the saliva transports its taste to our tastebuds．”由此可知，唾液能够把味道传给味蕾。)
5.What happens when the cooking smells disappear?
Some of the taste disappears too．
解析：(根据第三段最后一句“When the cooking smells disappear，so does some of the taste．”可知，当做饭时的味道消失后，一些味道也消失了。)
Sophie is from London, while Mohammed is from Sierra Leone. They are two teenagers with very different lives, but their lives are connected through charity. Sophie is taking part in a huge national event that raises money for people in the UK and abroad—a sponsored run for Sport Relief. Mohammed\’s village has a new well that was paid for with money from the same event. Every year Sport Relief and its sister charity, Comic Relief, raise money for good causes. By the end of this year, people will have completed more than 350 events. These events include marathons, football matches, talent shows and baking competitions, and when they are all completed, they will have raised over ￡50 million. That\’s enough money to transform the lives of thousands of people. Over the next few years, this money will be helping people like Mohammed.本文档预览：3500字符，共8740字符，源文件无水印，下载后包含无答案版和有答案版，查看完整word版点下载
