【解析】
21.C
句意：----飞往加拿大需要多长时间吗？ ---大约5小时。
How far多远，how often多久一次,how long多久,how much 多少，根据答句about 5 hours可知本题是多段时间提问，故选C。
22.A
句意：有些人习惯于在寒冷的早上晚起。
本题主要考查介词和介词短语。根据题意，有些人习惯于在（on）寒冷的早上晚起。on、in、at 都可以表示时间，但侧重不同。on 后常接具体的日子，in 后常接一段时间表示将来的时间，at 常接具体的时分。结合题意，on 符合题意。故选A。
23.B
句意：---你想喝点咖啡吗？
---是的。顺便问一下，你能在里面放些牛奶吗？
A总共，B顺便说一下，C有时候，D没关系，根据句意选B。
24.C
句意：我们校队和约翰队之间可能会有一场篮球赛。
本题考查maybe和maybe，maybe是副词，在句子中作状语；意为“也许，可能”，常位于句首，相当于perhaps， maybe中may为情态动词，be是动词原形，意为“也许是；可能有”
表示“可能会有”，且后接名词短语，应该用there may be，故选C
25.B
句意：鲍勃太粗心了，以至于错过了怀特先生演讲的全部内容。
A景色，B要点，C生意，D消息，根据句意选B。
26.D
句意：大多数人都同意Dick的意见而不是George，因为他们认为Dick的计划很好。
agree with sb“同意某人的意见”，结合后半句because they think Dick's plan is really good，可知大家不同意George的意见，故选D。
27.A
句意：上星期日我们在公园里玩得多开心啊！
根据 great fun we had in the park last Sunday!可知这里考查了感叹句，本句的中心词是fun，它是一个不可数名词，great是一个形容词，在这里修饰fun，根据What+形容词+可数名词复数/不可数名词+主语+谓语!故选A。
28.C
句意：---你将乘坐D5581还是乘坐G7619到杭州
---G7619。我将不得不花更多的钱, 但它会花更少的时间。
spend/cost/pay/take辨析：(1)spend的主语通常是人，往往用于以下句型: (sb)spend some money/some time on sth. (sb)spend some money/some time(in)doing sth。 (2)take常用于“占用、花费”时间，其主语通常为形式主语“it”或物。句式是: It takes/took sb.some time to do sth=Sth.takes sb.some time. (3) pay为“付款、赔偿”之意，主语通常是人，往往是sb. pays some money for sth或pay sb.(some money for sth)。(4) cost的主语必须是某物。spend … on sth./in doing sth.的主语必须是人。pay … for 的主语也是人。It takes + sb.+ 时间(或钱)to do sth.的主语则必须是形式主语It。 动词cost的常用用法是sth.cost (sb.) some money。所以选C。
29.D
句意：---为什么不停下来休息？
---它如此令人兴奋，以至于我情不自禁地做飞机模型。
stop doing sth.表示停止正在干的事情（一件事），stop to do sth.表示停下来去做另一件事（两件事），根据句意可知，第一个空是停下来休息，含两件事，第二个空是情不自禁地飞机模型了，一件事，故选D。
30.A
句意：---顺便问一下，你将如何过暑假
---我不知道。我还没决定。
A. 顺便问一下; B. 在途中 ;C.在某种程度上; D. 在某些方面。根据句意选A 。

Mark went to the neighborhood meeting after work.The neighborhood faced many problems，parking，crime and so on.It was too much for Mark. "The problems are too big，" He thought.He turned to the man next to him and said， "I think this is a waste of my time.Nothing I could do would make a difference here."
Mark thought some more on his way to the bus stop. "People should just take care of themselves，" He decided. "That's enough to do.I can't take on all the problems of the world."
As nearing the bus stop，Mark saw a woman carrying a grocery bag（杂货袋） and a baby.She was trying to unlock the car，but she didn't have a free hand.As Mark got closer，her other child，a little boy，suddenly rushed into the street.The woman tried to reach for him，but as she moved，her bag shifted and the groceries started to fall out.Mark ran to take the boy's arm and led him back to his mother.Then he picked up the groceries while the woman smiled in relief.
"Thanks!" She said. "You've got great timing!" "Just being neighborly，" Mark said.
As he rode home，Mark smiled and thought， "Maybe that's a good place to start." Mark didn't think he could make a difference for his neighbors because problems were too big.But now he knew he could do something for others.One can't imagine being a great man and doing a great deed overnight.But a little thing can make a difference.Even if you're the only one to take the first step，continue trying and others will someday work together，then we will solve even our greatest problems.

Life is full of choices and decisions. Here are some steps to help you make wise decisions.
First, it’s better to make a decision quickly than avoid it for a month because you’re afraid of choosing. ____11____ Also, some choices usually have time limits. So to keep our brains from getting too tired, we needn’t think about the cost of every single choice. Narrow down the list and try comparing only the best two or three.
Next, think about the value and cost of each choice. ____12____ Or better yet, create a scorecard,on which you give out bigger point values to what you think is more important. This way you can tell if one huge advantage is more important than a group of little disadvantages.
Then, stay calm and give yourself some space. You don’t want to delay(延迟) for weeks, but if you’re about to make a hasty(仓促的) decision, you may end up picking something you regret. ____13____ And it might take you a few days for major choices, like choosing your ideal high school.
____14____ Why Because it’s good to get a fresh way of thinking from others who are not as worried as you. Consider their opinions(观点) even if they are not what you want to hear. You need to take different opinions into consideration so that you will make a wise decision.
A．You’ll need at least one night to “sleep on it”. B．And you don’t have to make a decision alone. C．These ways of letting out what you are feeling are helpful. D．It’s very tiring to think things over but fail to decide in time. E．To do that, you can make a list of advantages and disadvantages.
三、短文填空
请认真阅读下面短文，并根据各题所给首字母的提示，写出一个合适的英语单词完整、正确的形式，使短文通顺。

【解析】
1.C
句意：---这个小男孩非常想念他的父母。---确实是这样．他们离开家快2年了。
本题考查短暂性动词和延续性动词区别及现在完成时。
根据for nearly two years可知，这是一个表示一段时间的时间状语，而leave是瞬间性动词，不能持续一段时间，所以要用be away from，它后面可以跟表示一段时间的状语，结合语境可知用现在完成时，现在完成时态的结构为have/has+动词的过去分词，主语是They，所以助动词用have，故选C。
2.D
句意：这个博物馆已经在这里80年了，它是这个城市里最老的建筑物之一。
本题主要考查现在完成时和一般现在时。第一个空，根据时间状语for over 80 years 可知这里要用现在完成时，have been 表示一种持续的状态。第二个空，表示陈述事实，故应该用一般现在时。故D项符合题意。故选D。
3.D
句意：---Amy，我们能捐赠这些柔软的玩具吗？我们已经买了很多年了。
---妈妈，但是我想留下这只熊。
本题考查现在完成时态，注意延续性动词的运用。for many years是判断用现在完成时态的关键词，其动词应该用延续性动词，buy是瞬间动词，所以应该用have；主语是we，助动词用have，动词have的过去分词为had，故选D。
4.B
句意： --我可以和布莱克先通话吗？
--对不起，他去香港了。但是他几天后回来。
本题考点是现在完成时和一般将来时。根据Sorry可知，说话人在说话的地方。have gone （to） 去了某地，现在不在说话的地方，故排除AC；又因为in a few days，表示“几天后”，用于将来时态中，排除D，故选B。
5.C
句意：---你哥哥有这台相机多久了？ ---两个星期。
本题考查现在完成时态的用法。根据答语for two weeks（两周）是一段时间，可知问句应为现在完成时态（基本结构：主语+have/has+动词的过去分词）表示持续到现在的动作，并且主句的动作应为可延续性的，可排除A，D。又问句主语your brother是第三人称单数，故可排除B，所以答案为C。
6.D
句意：---你要去哪里呢？
---我很快就要飞往美国了。我将于十月二日上午抵达纽约。
本题考查两个短语，第一个是arrive in +大地点/ at + 小地点，故第一空答案是in，在具体有一天的早晨用介词on，故本题选D。
7.A
句意：---Hobo和Eddie去电影院看电影《动物城》。
---哦，这就是我现在找不到它们的原因。
have/has been to表示去过某地,人已经回来;have/has gone to表示去了某地,人未回来.根据that's why I can’t find them now .可知人不在此地。主语是复数形式。故选A。
8.D
句意:---二班的所有男孩都去了操场除了王东。为什么？
---因为他的右腿出了问题。
except作介词，意为“除……之外(不再有)”。指从整体中排除except所带的人或物，前面常有all，every，any，no及其他限定词。
besides作介词，意为“除……之外(还有)”。相当于as well as。指在原来的基础上加上besides后接的宾语(人或物)。
but作介词，意为“除……之外”。其常与否定意义的词连用；当but前有实义动词do或其相关形式时，but后接不带to的不定式。
except for意为“除了……”。它后面接的词同句子的整体词(主语)不同类，指从整体中除去一个细节或方面。根据句意，本题选D。
9.C
句意：多么令人激动的消息！你对去北京不感到兴奋吗？
exciting主语是物或事；excited主语为人较多。故选C。
10.A
句意：电影上映五分钟了，所以我们看下一场吧。
句中的时间状语"for+时间段"是现在完成时的标志，且句子中的谓语动词必须是延续性动词，现在完成时的构成是：主语+have/has+动词的过去分词； 选项中，start是非延续性动词，转换成be on 可以与时间段连用，表示动作延续了多长时间。故选A。
