6．A Koala Isn't a Bear
Koalas remind people of teddy bears．They have thick fur and large ears．Their broad，flat nose makes them look cute，similar to teddy bears．In fact koalas aren't cute．They have sharp teeth and very sharp claws!Koalas are marsupials．This means the mother carries her baby in a pocket while it develops，similar to a kangaroo．The baby koala lives in its mother's pocket for the first six months of its life．
The name"koala"comes from a native Australian word that means"no drink"．The koalas get almost all their water from the eucalyptus（桉树） leaves they eat．That's where they get their food too．Koalas eat only eucalyptus leaves，and only the leaves of certain eucalyptus trees．The eucalyptus trees are where the koalas live．It's also where they sleep．Koalas sleep about nineteen hours a day!
Why do they sleep so much？Some people think it's because they're lazy．But koalas aren't lazy．They sleep so much because there isn't much nutrition in eucalyptus leaves．Koalas store hardly any fat，so they must save their energy．One way to do this is to move slowly and sleep a lot．
After a day of sleeping they like to move around and eat just after sunset．They live alone most of the time．Koalas are very protective of their trees．If a koala sees another koala eating in its favorite tree，it might tell the other koala to leave by"barking"at it．Koalas do"talk"to each other．Besides barks，the males make a deep grunting sound．The mothers and babies talk in soft clicking sounds．If they get scared they may scream like a baby．

A．They both have thick fur．
B．They both have sharp teeth．
C．They both eat eucalyptus leaves．
D．They both carry their young in a pocket．

17．Baby girls make their way directly for dolls as soon as they can crawl，while boys will head for the toy cars，a study has shown．The findings，the first to show differences in very young babies，suggest there is a biological（生物学的） basis（基础） to their preferences（偏爱）．
Psychologists（心理学家） Dr．Brenda Todd from City University London carried out an experiment involving 90infants（婴儿） aged nine months to 36months．The babies were allowed to choose from seven toys．Some were stereotypically boys'toys-a car，a digger，a ball and a blue teddy．The rest were girls'toys：a pink teddy，a doll and a cooking set．They were placed a meter away from the toys，and could pick whichever toy they liked．Their choice and the amount of time they spent playing with each toy were recorded．
Of the youngest children （nine to 14months），girls spent significantly（明显的） longer playing with the doll than boys，and boys spent much more time with the car and ball than the girls did．Among the two-and three-year-olds，girls spent 50percent of the time playing with the doll while only two boys briefly（简单地） touched it．The boys spent almost 90percent of their time playing with cars，which the girls barely（几乎不） touched．There was no link between the parents'view on which toys were more appropriate for boys or girls，and the children's choice．
Dr Brenda Todd said："Children of this age are already exposed （暴露）to much socialization（社会化）．Boys may be given‘toys that go'while girls get toys they can care for，which may help shape their preference．But these findings agree with the former idea that children show natural interests in particular kinds of toys．There could be a biological basis for their choices．Males through evolution have been adapted to prefer moving objects，probably through hunting instincts（本能），while girls prefer warmer colours such as pink，the colour of a newborn baby．"

31．Baby boys and girls have different toy preferences probably becauseD．
A．baby boys are much more active
B．baby girls like bright colours more
C．their parents treat them differently
D．there is a natural difference between them
32．Both baby boys and baby girls like to play withB  according to the study．
A．a ball          B．a teddy
C．a car           D．a doll
33．What can we infer from Paragraph 3？C
A．Nine-month-old baby boys don't play with dolls at all．
B．Two-year-old baby girls sometimes play with cars and balls．
C．The older the babies are，the more obvious their preference is．
D．Parents should teach their babies to share each other's toys．
34．What conclusion did Dr．Brenda Todd draw from the results of the study？B
A．Adults purposely（故意地） influence their babies preference．
B．Babies'preference isn't affected by social surroundings．
C．Baby boys preferring to moving toys will be good at hunting．
D．Baby girls preferring warmer colors will be warm-hearted．
35．We may read this article in aA section of a newspaper．

1．For better eyesight，doctors advise limiting the hours of screen time and encourage having enough eye resting time．However，another study shows that sitting in front of compute or TV screens for long hours is not the only reason for myopia （近视）．An Australian research team studied young children in Sydney and Singapore to find the reasons for myopia．The research team found that there were less children who had myopia in Sydney than those in Singapore，even though they spent more time in front of computer and TV screens．The major finding is that children in Sydney spend longer hours on outdoor sports than those in Singapore．
Indoor and outdoor sports both make the eyes pay attention to more distant objects，which stops the eyes from changing original shape．But outdoor sports may be better than indoor sports for myopia．Because natural light is good for eye growth and vitamin D from the sunlight might be useful to it．Many doctors suggest that every child get its first eye test when he/she is about two and half years old，and even if his/her sight seems good enough．It is necessary for myopic （近视的）children to wear glasses to stop headaches，trouble reading and so on．It is also important that schools invite doctors to test their students eyes．
If that is not possible，school teachers should at least encourage parents and children to have regular eye examination and wear glasses．And parents should remember not only to limit the total screen time for their children，but also to encourage them to spend time outdoors．

28．Why are there fewer children with myopia in Sydney than those in Singapore？D
A．Because the children in Sydney watch TV less．
B．Because the children in Sydney have more eye resting time．
C．Because the children in Sydney use computer less．
D．Because the children in Sydney do more outdoor sports．
29．What is good for eye growth according to the passage？C
A．Natural light．
B．Vitamin D．
C．Natural light and Vitamin D．
D．The sun．
30．Which of the following is TRUE？B
A．Children should have eye tests as soon as they reach school age．
B．Looking more at distant objects can help the eyes keep their original shape．
C．Doing outdoor sports with no glasses is good for myopic children．
D．Children should limit their time in the sun to protect their eyes
31．The passage mainly tells usC．
A．the children in Sydney spend more time in front of screens
B．the children in Singapore like outdoor sports
C．doing outdoor sports and limiting the hours of screen time are good for eyes
D．it's important to test students'eyes．

18．Everyone needs friends．There is an old saying，"Friends are God's way of taking care of us．"But how do you find real friendship and keep it？
The American writer Sally Seamans tells young students some smart ways to find friends．Sally says finding friendship is just like planting a tree．You plant the seed and take care of it to make it grow．
First，you should choose a friend．What makes a good friend？It is not because a person has money or good looks．A good friend should be kind and patient．For example，if you have a bad day，a good friend should listen to your complaints and do his or her best to help．To make a friend，you cannot be too shy．You should make each other happy and share your lives．
But things cannot always be happy．Even the best friends have fights．What should you do when you have a fight with your friend？You have to talk to him or her．When there is no one around，have an honest talk．If he or she doesn't want to talk，you could write a letter．
There are three steps to being friends again：
Tell him or her how you are feeling； say what your friend has done wrong，and explain why you did this or that．Remember that friendship is the most important thing in your life．

15．Do you know of anyone who uses the truth to deceive （欺骗）？When someone tells you something that is true，but leaves out important information that should be included，he can give you a false picture．
For example，some might say，"I just won a hundred dollars on the lottery （彩票）．It was great．I took that dollar ticket back to the store and turned it in for one hundred dollars!"
This guy's a winner，right？Maybe，maybe not．We then discover that he bought $200worth of tickets，and only one was a winner．He's really a big loser!
He didn't say anything that was false，but he left out important information on purpose．That's called a half-truth．Half-truths are not technically lies，but they are just as dishonest．
Some politicians often use this trick．Let's say that during Governor Smith's last term，her state lost one million jobs and gained three million jobs．Then she seeks another term．One of her opponents （对手） says，"During Govemor Smith's term，the state lost one million jobs!"That's true．However，an honest statement would have been，"During Govemor Smith's term，the state had a net gain of two million jobs．"
Advertisers（广告商） will sometimes use half-truths．It's against the law to make false statements so they try to mislead you with the truth．An advertisement might say，"Nine out of ten doctors advised their patients to take Yucky Pills to cure toothache．"It fails to mention that they only asked ten doctors and nine of them work for the Yucky Company．
This kind of deception happens too often．Lt's a sad fact of life：Lies are lies，and sometimes the truth can lie as well．
32．How much did the lottery winner lose？A
A．One hundred dollars．
B．Two hundred dollars．
C．Three hundred dollars．
D．Four hundred dollars．
33．We may infer that the author believes people shouldC．

D．not trust the Yucky Company
34．What do the underlined words"net gain"in Paragraph 5mean？A
