5.As we know,____ most dangerous enemies are those who pretend to be ____ friends(  )
A.不填; 不填B.the; theC.不填; theD.the; 不填

分析 正如我们都知道的,最危险的敌人是伪装成我们朋友的那些人!

解答 答案:D
根据句意可知,"____ most dangerous enemies"指"最危险的敌人",这里表示形容词的最高级,故用定冠词the;第二个空表示泛指"朋友们",因此friends前不加任何冠词;故选D

点评 本题考查了冠词的用法;需要了解的是形容词,副词的最高级的前面应加定冠词the;名词的复数形式表示泛指时,不加任何冠词;另外,应熟练掌握定冠词,不定冠词以及零冠词的用法区别.

19.Most people agree that honesty is a good thing.But does Mothe r Nature agree?Animals ca n't talk,but can they lie in other ways?Can they lie with their bodies and behavior?Animal experts may not call it lying,but they do agree that many animals,from birds to chimpanzees,behave dishonestly to fool other animals.Why?Dishonesty often helps them survive.
Many kinds of birds are very successful at fooling other animals.For example,a bird called the plover sometimes pretends to be hurt in order to protect its young.When a predator(猎食动物)gets close to its nest,the plover leads the predator away from the nest.How?It pretends to have a broken wing.The predator follows the"hurt"adult,leaving the baby birds safe in the nest.
Another kind of bird,the scrub jay,buries its food so it always has something to eat.Scrub jays are also thieves.They watch where others bury their food and steal it.But clever scrub jays seem to know when a thief is watching them.So they go back later,unbury the food,and bury it again somewhere else.
Birds called cuckoos have found a way to have babies without doing much work.How?They don't make nests.Instead,they get into other birds'nests secretly.Then they lay their eggs and fly away.When the baby birds come out,their adoptive parents feed them.
Chimpanzees,or chimps,can also be sneaky.After a fight,the losing chimp will give its hand to the other.When the winning chimp puts out its hand,too,the chimps are friendly again.But an animal expert once saw a losing chimp take the winner's hand and start fighting again.
Chimps are sneaky in other ways,too.When chimps find food that they love,such as bananas,it is natural for them to cry out.Then other chimps come running.But some clever chimps learn to cry very softly when they find food.That way,other chimps don't hear them,and they don't need to share their food.
As children,many of us learn the saying"You can't fool Mother Nature."But maybe you can't trust her,either.

13.Third-Culture Kids
Did you grow up in one culture,your parents came from another,and you are now living in a totally different country?If so,then you are a third-culture kid!
The term"third-culture kid"(or TCK) was coined in the 1960s by Dr.Ruth.She first came across this phenomenon when she researched North American children living in India.Caught between two cultures,they form their very own.(71)B  About 90percent of them have a university degree,while 40percent pursue a postgraduate or doctor degree.They usually benefit from their intercultural experience,which helps them to grow into successful academics and professionals.
(72)AIn fact many hardships may arise from this phenomenon.A third-culture kid may not be able to adapt themselves completely to their new surroundings as expected.Instead,they may always remain an outsider in different host cultures.Max,for example,experienced this fundamental feeling of strangeness throughout his life as a third-culture kid.(73)GWhile this can be a way to create a network of friends all around the world,it can be difficult for a third-culture kid like Max to maintain close friendships and relationships.
For a third-culture kid,it is often easier to move to a new foreign country than to return to their"home"country.After living in Australia and South Korea for many years,Louis finally returned to Turkey as a teenager.But she felt out of place when she returned to the country where she was born.(74)FShe did not share the same values as her friends'even years after going back home.
While a third-culture kid must let go of their identity as foreigner when he/she returns,the home country can prove to be more foreign than anything he/she came across before.The peer group they face does not match the idealized image children have of"home".(75)C
As a part of the growing"culture",TCKs may find it a great challenge for them to feel at home in many places.

A.Yet being a third-culture kid is not always easy.
B.In general,they often reach excellent academic results.
C.This often makes it hard for them to form their own identity.
D.However,their parents can help them see the opportunities of a mobile lifestyle.
E.Their experience abroad helps them to gain a better understanding of cultural differences.
F.Unlike other teens of her age,she didn't know anything about current TV shows or fashion trends.
G.Additionally,making new friends and saying goodbye to old ones will at some point become routine for a third-culture kid.
