10．Heis sitting  （sit） on the grass now．

分析 他現(xiàn)在正坐在草地上．

解答 答案：is sitting．考查現(xiàn)在進(jìn)行時(shí)．根據(jù)"now"，現(xiàn)在，結(jié)合句意可知，說(shuō)話(huà)時(shí)他應(yīng)該正在坐在草地上．用現(xiàn)在進(jìn)行時(shí)，即am/is/are+doing．主語(yǔ)為he，用is．sit的現(xiàn)在分詞為sitting．

點(diǎn)評(píng) 考查時(shí)態(tài)的題，可根據(jù)題干中的時(shí)間和句意確定時(shí)態(tài)．

20．Michael，Rae，Jequita，Alice，Sarah and Phyllis have at least one thing in common：They all love animals so much that they're driven to volunteer regularly at the Romulus Animal Shelter．
The six Romulus-area residents give as much time as they can to perform various tasks at the shelter，help make life more comfortable for the dogs and cats that stay there and do their best to find permanent homes for the stray（流浪）pets．
The shelter，at 12300 Wayne Road，opened in June 2011and operates on money raised in the community．To date，bingos and other fundraising activities have brought in more than＄177.000，according to community leader William Wadsworth，but a tight budget requires the efforts of volunteers to make ends meet．
"Without their help，this building would not be an outstanding place，"Wadsworth said．"Their time and devotion is beyond what I ever expected．And I thank them all．"
The volunteers work at the direction of two animal control officers，Annie Hall and Kim Ratcliff，who spend much of their day patrolling（巡邏）the city and housing stray dogs and cats．The two，both with 32 years of experience，count on the public to be the eyes and cars of the shelter．They are also responsible for addressing complaints and taking care of the shelter．
That's where the volunteers come in．They take photos of the animals and post them on Facebook and other websites for adoption．They clean cages，play with the animals，feed and bathe the pets and take the dogs for walks．They pick up supplies and even clean the restrooms．
"We couldn't do it without them，"said Ratcliff．"They come in and go right to work．We depend on them a lot．They help run the place，"added Hall．

1．How to be politeBeing polite is a matter of good manners； it's about respect，and being considerate of people's feelings，culture，and values．It does not seem difficult，but for many people it remains a challenge．While some people have no interest whatsoever in manner，if you are reading this you're probably wondering how you can improve your manners．At the very least，you might want to know how to avoid being rude，which can put off the people around you．Being polite is also a good way to make friends．
（61）F Loudness either indicates arrogance or insecurity．A charming polite person makes another person feel good．Keep this goal in mind．Be considerate of other people's needs and opinions．Don't make unfavorable remarks towards any kind of ethnic，political or religious groups under any circumstances．
（62）D You might want to practice this a bit so you don't squish （攥緊） people's hands，depending on how strong you are．That would make them feel uncomfortable．Beware especially when shaking hands of women who are wearing rings．Too much pressure can be very painful．Remember too that many people with an"old-school"etiquette background （especially if you are in Europe） find it inappropriate to offer your hand for a handshake to a lady or an older gentleman if you are a gentleman，or to an older lady，if you are a lady．
（63）E Try not to talk about yourself too much-if they want to know （or are polite） they'll ask．Be confident and charming．Do not hog the conversation，which is too rude．Look interested and listen to the answers．Don't look over the person's shoulder or around the room when they are talking，or let your eyes linger on the hot new guest who just walked in．That implies that you are distracted or not interested-that your conversational companion is not important or interesting enough to bother paying attention to．
（64）A Always be courteous （客氣的），as you might meet this person again in another setting and wouldn't want to have caused negative memories that would give you a bad standing．If someone annoys or even insults you，don't get into an argument．Say"Let's agree to disagree"and change the subject，politely debate，or simply excuse yourself from the conversation．
（65）C For silverware，go from the outside in．Place your napkin on your lap，and do not add anything to the table that was not there when you got there （cell phone，glasses，jewelry）．Put your purse between your feet，under your chair．Women should not apply makeup at the table．It is rude and demonstrates a lack of refinement．If you want to fix your makeup or check if something is in your teeth，go to the restroom．

A．Be nice．
B．Be aware that manners vary．
C．Know the proper dinner manners．
D．Shake hands firmly and look them in the eyes when doing so．
E．Start a conversation by asking questions about the other person．
F．Have a laugh which shows you are having fun，without being loud．

15．A little boy decided to go for a swim in the old swimming hole behind his house on a hot summer day in America．He dived into the cool water，not realizing that as he swam towards the middle of the lake，a crocodile （鱷魚(yú)） was swimming toward him．
His mother in the house was looking out of the window and saw the two as they got closer and closer．In great fear，she ran toward the water，shouting to her son as loudly as she could．Hearing her voice，the little boy became alarmed and made a U-turn to swim to his mother．It was too late．Just as he reached her，the crocodile reached him．From the shore，the mother grabbed her little boy by the armsjust as the crocodile snatched his legs．That began an incredible tug-of-war （拔河） between the two．The crocodile was much stronger than the mother，but the mother was much too passionate to let go．A farmer happened to drive by，heard their screams，raced from his truck，took aim and shot the crocodile．
Remarkably，fter weeks and weeks in the hospital，the little boy survived．His legs were extremely scarred by the attack of the animal．And，on his arms，were deep scratches where his mother's fingernails dug into his flesh in her effort to hang on to the son she loved．
The newspaper reporter，who interviewed the boy，asked if he would show him his scars．The boy lifted his legs．And then，with obvious pride，he said to the reporter，"Bt look at my arms．I have great scars on my arms，too．I have them because my Mom wouldn't let go．"
Never judge another person's scars，because you don't know how they were made．
