我想请教一个英语阅读的问题
Do dogs understand us?
Be careful what you say around your dog.It might understand more than you think.
A border collie named Rico recognizes the names of about 200 objects,say researchers in Germany.The dog also appears to be able to learn new words as easily as a 3-year-old child.Its word-learning skills are as good as those of a parrot or chimpanzee(黑猩猩).
In one experiment,the researchers took all 200 items that Rico is supposed to know and divided them into 20 groups of 10 objects.Then the owner told the dog to go and fetch one of the items and bring it back.In four tests,Rico got 37 out of 40 commands right.As the dog couldn't see anyone to get clues,the scientists believe Rico must understand the meanings of certain words.
In another experiment,the scientists took one toy that Rico had never seen before and put it in a room with seven toys whose names the dog already knew.The owner then told Rico to fetch the object,using a word the dog had never heard before.
The correct object was chosen in seven out of l0 tests,suggesting that the dog had worked out the answer by process of elimination(排除法).A month later,Rico remembered half of the new names,which is even more impressive.
Rico is thought to be smarter than the average dog.For one thing,Rico is a border collie,a breed (品种)known for its mental abilities.In addition,the 9-year-old dog has been trained to fetch toys by their names since the age of nine months.
It's hard to know if all dogs understand at least some of the words we say.Even if they do,they can't talk back.Still,it wouldn't hurt to sweet-talk your dog every now and then.You might just get a big,wet kiss in return!
60.From paragraph 2 we know that __ .
A.animals are as clever as human beings
B.dogs are smarter than parrots and chimpanzees
C.chimpanzees have very good word-learning skills
D.dogs have similar 'learning abilities as 3-year-old children
C,我想知道为什么不选D.我的根据是第二段的第二句话.我们老师说那句话的意思是,狗也能学一些像3岁小孩能学的一样的简单的新单词.可我觉得她说的不对,我觉得应该是,狗也表现出可以像三岁小孩一样容易的学新单词.也就是说狗学单词像三岁小孩一样容易.那样答案就是D了.

The dog also appears to be able to learn new words as easily as a 3-year-old child
这句话的意思是:狗狗表现出和三岁小孩一样的学习新单词的能力.
但是选项D 的意思是狗狗有何三岁小孩一样的能力.
这两句话的意思不一样,一个是学习新单词的能力,一个是学习的能力,范围不一样大,学习的能力包括学习新单词的能力,比如三岁小孩会讲话,狗狗不会.
所以不能选择D.
希望帮到你哦!
