B．

to understand

C．

understanding

D．

understood

分析从纽约来的老太太当她用不地道的汉语让别人明白她自己时很高兴．

解答答案：D 考查过去分词．herself与understand之间是动宾关系，用过去分词作宾语补足语．故选D．A项：动词原形；B项：动词不定式；C项：现在分词．

点评非谓语动词作状语．它的逻辑主语就是句子的主语．因此关键看它和句子主语之间的关系．如果是和句子主语之间构成主动关系，使用现在分词，若构成被动关系，使用过去分词．若表目的，使用不定式．

11．Today，many species of animals and plants are endangered．This means they are in danger of becoming extinct and living on only in the pages of history books．The famous dodo is a classic example of a creature that became extinct．A flightless bird that lived on the island of Mauritius，it was discovered by sailors in 1598but was hunted to extinction by 1681．
Hunting has caused the Bengal tiger and the African elephant to be endangered today but habitat destruction can also lead to extinction．This is equally true for plants．Animals and plants disappear for other reasons too，but the main cause is often a disruption（打乱，破坏） in the natural food chain，whether due to hunting，habitat destruction，or even the introduction of alien species．
The natural food chain is the cycle that governs the existence of all life on this planet．It is a carefully balanced cycle and any imbalance that occurs can cause knock-on effects that have serious consequences．At the beginning of the natural food chain are plants which turn sunlight into energy and draw nutrients from the earth．Plants are called producers．
After the producers come the consumers．There are three tiers of consumers．First are creatures such as plant-eating animals，fish and insects which feed off the producers．These animals that only eat plants are called herbivores．The second tier of consumers are carnivores-animals that live off other animals．The third tier of consumers eats both other animals and plants．These consumers，including most humans，are called omnivores．
After animals and plants die，they become food for other smaller creatures，such as bacteria and some plants，such as fungi．As they feed，these creatures turn the dead bodies back into gases and minerals which are again food for the producers at the beginning of the food chain．And so the cycle continues．
All of nature is connected and governed by hundreds of these delicate food chains and if a single plant in the chain cannot survive，then the insects that live off the plant start to die and the animals that eat the insects also start to die．
When a food chain is disrupted，the consequences can be extremely serious．One estimate suggests that for each plant species that is lost，up to 30animals and insects may also die out．One wonders how many species were affected by the extinction of the dodo？
Humans can have disastrous effects on food chains．We've already mentioned hunting but now let's look at travel．When people first started to explore the world they took plant and animal species from their home countries and introduced them wherever they went．They didn't realize that by introducing alien species they were disrupting the natural food chains of the areas they discovered．Although there are strict rules in place today controlling the import and export of alien species，some places are still fighting the effects of aliens introduced hundreds of years ago．
For example，Gough Island in the South Atlantic Ocean is a breeding ground for albatrosses that have been nesting there for centuries．But in the 19th century，mice from passing ships were brought to the island．Being a species alien to the island，they had no natural predators and have now grown to such a size that they are attacking and killing albatross chicks．If they are allowed to continue，they will wipe out the albatross population．
With import laws and people's rising awareness of how humans affect the natural environment，hopefully we can learn to fit better into the natural food chains that govern our world．Otherwise we need to accept that the loss of any more plants and animals could eventually mean our own extinction．

18．As a young boy，I sometimes traveled the country roads with my dad．He was a rural mail carrier，and on Saturdays he would ask me to go with him．Driving through the countryside was always an adventure：There were animals to see，people to visit，and chocolate cookies if you knew where to stop，and Dad did．
In the spring，Dad delivered boxes full of baby chickens，and when I was a boy it was such a fun to stick your finger through one of the holes of the boxes and let the baby birds peck on your fingers．
On Dad's final day of work，it took him well into the evening to complete his rounds because at least one member from each family was waiting at their mailbox to thank him for his friendship and his years of service．"Two hundred and nineteen mailboxes on my route．"he used to say，"and a story at every one．"One lady had no mailbox，so Dad took the mail in to her every day because she was nearly blind．Once inside，he read her mail and helped her pay her bills．
Mailboxes were sometimes used for things other than mail．One note left in a mailbox read．"Nat，take these eggs to Marian； she's baking a cake and doesn't have any eggs．"Mailboxes might be buried in the snow，or broken，or lying on the groom，but the mail was always delivered．On cold days Dad might find one of his customers waiting for him with a cup of hot chocolate．A young wrote letters but had no stamps，so she left a few buttons on the envelope in the mailbox； Dad paid for the stamps．One businessman used to leave large amounts of cash in his mailbox for Dad to take to the bank．Once，the amount came to 32，000．
A dozen years ago，when I traveled back to my hometown on the sad occasion of Dad's death，the mailboxes along the way reminded me of some of his stories．I thought I knew them all，but that wasn't the case．
As I drove home，I noticed two lamp poles，one on each side of the street．When my dad was around，those poles supported wooden boxes about four feet off the ground．One box was painted green and the other was red，and each had a long narrow hole at the top with white lettering：SANTA CLAUS，NORTH POLE．For years children had dropped letters to Santa through those holes．
I made a turn at the comer and drove past the post office and across the railroad tracks to our house．Mom and I were sitting at the kitchen table when I heard footsteps．There，at the door，stood Frank Townsend，Dad's postmaster and great friend for many years．So we all sat down at the table and began to tell stories．
At one point Frank looked at me with tears in his eyes．"What are we going to do about the letters this Christmas？"he asked．
"The letters？"
'I guess you never knew．"
"Knew what？"
"Remember，when you were a kid and you used to put your letters to Santa in those green and red boxes on Main Street？It was your dad who answered all those letters every year．"
I just sat there with tears in my eyes．It wasn't hard for me to imagine Dad sitting at the old table in our basement reading those letters and answering each one．I have since spoken with several of the people who received Christmas letters during their childhood，and they told me how amazed they were that Santa had known so much about their homes and families．
For me，just knowing that story about my father was the gift of a lifetime．

16．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 （有袋类动物）．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．
