10.Humans have five senses:sight,hearing,smell,taste and touch.They collect information for the brain.For example,the eyes collect information on pictures and the ears collect information on sounds.
Sometimes a person loses a sense.Their other senses become better.For example,a blind person has much better senses of hearing and touch.
Sight
The eyes can only see with light.Light carries the picture of something into the eyes so humans can see it.But do you know that the picture is upside down?The brain has to turn the picture the right way up again.
Hearing
Sounds travel through the air like waves (波).Human ears are like cups.They catch sound waves for the brain and the brain translates them as different sounds.
Smell
Humans smell with their noses.Most people can recognize about 10,000 kinds of smell.This is amazing!Humans each have five million receptor cells (感受细胞)in their noses.Noses are not only for smelling.They also clean and warm the ail that people breathe in.How does the nose prevent the dirty air from getting into the body?Well,it sneezes(打喷嚏)!
Touch
There are receptor cells for the sense of touch all over the body.This is different from the other senses.Touch receptor cells are in the lowest part of the skin.They help the body to have all kinds of feelings like pain,cold and heat.Some parts of the body (like the finger) are more sensitive(敏感的)than other parts of the body (like the back) because they have more touch receptor cells.
Taste
People can taste food because they have about 10,000 taste buds(味蕾)on their tongues.Old taste buds die and new ones come out every two weeks.But when people get older,this happens less often.That's why old people often complain their food is tasteless.Scientists also find that smokers have fewer taste buds.Do you want food to taste good?Well,don't smoke!
For hundreds of years,people knew the basic tastes were sour,sweet,salty and bitter(苦).In 2002,a fifth taste,umami(delicious taste) joined the list.Now,a study from Purdue University in the US found that fat could actually be the sixth basic taste.
To be considered a basic one,a taste needs to beable to active certain receptor cells in the mouths.A study has shown that humans have fat receptors in the mouths.Not long after that,a scientist made a study to test a second question:can people taste the difference between fat and other tastes?
Richard Mattes gave the testers six different kinds of things.Each kind had a taste:sweet,salty,sour,bitter,umami or the newcomer-fat.Mattes asked the people to pick out tastes by their differences.This was to test whether or not fat would be picked out from the group.Most of tlie testers could clearly find out the different taste of fat.
Then how does fat taste?"It's terrible."Mattes said."However,the taste can be pleasant in a small amount,just as we enjoy the bitterness of chocolate."

分析 【文章大意】这篇文章主要讲述了人类有五种感觉:视觉、听觉、嗅觉、味觉和触觉. 它们为大脑收集信息.比如眼睛收集图象的信息,耳朵收集声音的信息.并且,几百年来,人们知道基本的口味是酸、甜、咸、苦. 在2002年,第五种味道,鲜味加入了其中.现在,美国普渡大学的一项研究发现,脂肪可能是第六基本的味道.

解答 111.parts of the body/collectors/organs.考查总称.根据表格中 eyes,ears,nose,tongue 都是身体的一部分,所以填parts of the body/collectors/organs.
112.brain.考查名词. 根据原文Sight部分的Light carries the picture of something into the eyes so humans can see it.But do you know that the picture is upside down?The brain has to turn the picture the right way up again.可知由光形成的影像和人脑中的影像是不同的.故填brain.
113.translating.考查动词.根据原文Hearing部分的"They catch sound waves for the brain and the brain translates them as different sounds."可知它们抓住声波并对大脑将它们转化为不同的声音.故填translating.
114.take out.考查动词短语.根据原文Smell部分的How does the nose prevent the dirty air from getting into the body?Well,it sneezes (打喷嚏)!可知打喷嚏可以清除吸入的不干净的空气.故填take out.
115.skin.考查名词.根据Touch部分的Touch receptor cells are in the lowest part of the skin.They help the body to have all kinds of feelings like pain,cold and heat.,可知触摸感受器细胞在皮肤的最低点,它们帮助身体有各种各样的感觉,像疼痛、寒冷和热.故填skin.
116.because of.考查介词短语.根据Touch receptor cells are in the lowest part of the skin.They help the body to have all kinds of feelings like pain,cold and heat.可知触摸感受器细胞在皮肤的最低点,因为它们帮助身体有各种各样的感觉,像疼痛、寒冷和热.前后两句为因果关系,because of为介词短语,后面接名词或者代词.故填because of.
117.causes.考查动词.根据原文Old taste buds die and new ones come out every two weeks.But when people get older,this happens less often.That's why old people often complain their food is tasteless.说明味蕾的减少会导致老人尝不出味道.故填cuases.
118.basic tastes.考查名词.根据文章倒数第四段的For hundreds of years,people knew the basic tastes were sour,sweet,salty and bitter (苦).可知,酸甜苦辣是基本的味道.故填basic tastes.
119.more.考查副词.根据倒数第三段的A study has shown that humans have fat receptors in the mouths.Not long after that,a scientist made a study to test a second question:can people taste the difference between fat and other tastes?推断出另一个更多的研究证明人们可以区分出脂肪.故填more.
120.tell.考查动词.根据原文倒数第二段的This was to test whether or not fat would be picked out from the group.Most of the testers could clearly find out the different taste of fat.得知这是为了测试是否将挑出脂肪,大部分的测试人员可以清楚地找出不同味道的脂肪,应填tell.
