　　“种菜”小心栽进广告陷阱

　　Here's an idyllic(和平美丽的)scene: a small village where the sun always shines, crops always grow and your friends drop by to sweep your yard to the sound of guitar music. Animals do what they are told, there is no disease, and lending “folks a helping” hand makes you richer and wiser.

　　The new herd, however, is nothing more than a collection of computer­generated cartoons. FarmVille is an online computer game built into the social networking site Facebook and is described by its players as “addictive”. Players are given a patch of ground with six fields, “cash”， a few seeds and a plough and have to build up wealth, skills and neighbours to create bigger, better, richer farms.

　　Inviting your online friends to play means you earn more and get free gifts; you rise rapidly through the first levels but, once hooked, have to work harder and harder with no final level or goal in sight.

　　答案：B

　　1．anyhow adv. 无论如何；即使如此

　　观察下面句子，体会anyhow的不同意义：

　　Anyhow I must get all the work done before Monday.(无论如何)

　　I am not feeling quite well, but I will attend the meeting tomorrow anyhow.(即使如此)

　　I was in such a hurry that I put my clothes on anyhow.(随便地，胡乱地)

　　点拨：(1)anyhow用于表达“无论如何，不管怎样，即使如此”时可与anyway互换，常用于让步状语，位于句中；其前常有but，或者也可在句末。

　　(2)表示“况且，更何况，再说，至少”时，anyhow与anyway都用作状语，用于对前面的话作补充，给出一个更充分的令人信服的理由。

　　(3)作“随意地，杂乱地，无辜地”讲时，不能用anyway而只能用anyhow。

　　[归纳拓展]

　　somehow表示“以某种方式，不知怎么地”，与anyhow意义不同；

　　somewhat adv. 稍微；有些，常用来修饰形容词或副词。

　　Somehow,_he lost his way in the fog.

　　不知道怎么地，他在大雾中迷路了。

　　He was somewhat surprised to see his father sitting at the back of the classroom.

　　看到父亲坐在教室后面，他感到有些惊讶。

　　[运用提升]

　　There is little chance that we will succeed in changing the law.________， it is important that we try.

　　A．But　B．Anyhow

　　C．Somewhat

　　D．Anywhere

　　答案：B　句意：我们要成功地改变法律的可能性不大，但不管怎样(尽管如此)，尝试还是很重要的。anyhow“不管怎样，尽管如此”；somewhat“有点，有几分”；anywhere“不管哪里，在任何地方”。

　　2．signal vi. & vt. 发信号　n. 信号

　　He signalled(to)the waiter for the bill.

　　他示意服务员结账。

　　[归纳拓展]

　　(1)signal (to)sb. to do sth. 示意某人做某事

　　signal (sb.)that... 示意……

　　(2)a danger/warning/stop signal 危险/警告/停车信号

　　traffic signals 交通信号灯

　　辨析：symbol, signal, sign, mark

　　(1)symbol 指符号、象征、标志等。

　　(2)signal 指信号、暗号或警告等。

　　(3)sign 表示“记号，符号”时，同“symbol”。表示“告示，指示牌”时，侧重指用图画、文字表达的告示、图示，此外还可以理解为“迹象，征兆”。

　　(4)mark普通用词，含义广泛。 既可指为便于辨认而有意做的标记，又可指自然形成的标记或有别于其他事物的特征。

　　①Red is a symbol of danger.

　　红色是危险的象征。

　　②Dark clouds are usually a sign of rain.

　　乌云往往是下雨的征兆。

　　[运用提升]

　　②New problems will arise one after another in future.(出现)

　　③They arose at sunrise to get an early start to the park.(起床)

　　④A curl of smoke is arising out of the chimney.(上升)

　　⑤Accidents often arise_from carelessness.[(由)……产生]

　　[归纳拓展]

　　(1)arise表示“出现，发生”之意时，其主语多为problem, argument, quarrel, danger, movement, question等抽象名词，多指不好的事情发生或出现。

　　(2)arise from/out of由……而引起；由……而产生；从……中产生

　　辨析：arise, arouse, rise, raise

　　(1)arise (arose, arisen, arising) vi. 出现，发生，起因于

　　②The wife kept silent all_the_way back home.

　　回家的路上，妻子一句话也没说。

　　点拨：表达“在某种程度上”时，还可用in a sense, to a/some degree及to an/some extent三个短语。

　　[运用提升]

　　—I think he is taking an active part in social work.

　　—I agree with you ________.

　　A．in a way　B．on the way

　　C．by the way

　　D．in the way

　　答案：A　本题考查介词短语。in a way＝in one way“在某种程度上”；on the way“在途中”；by the way“顺便说一下，顺便问一下

　　”； in the way“挡道；碍事”。由句意“我在某种程度上同意你所说的”可知应选A项。

　　6．deal with处理；安排；对付

　　观察下列句子，了解deal with短语的不同意义：

　　①We have been dealing_with the firm since the early 1990s.(和……做买卖)

　　②In the process, the children learn how to deal_with difficulties.(处理)

　　③His article deals_with many issues we are greatly concerned about.(涉及)

　　④The lady is hard to deal_with.(对付)

　　[归纳拓展]

　　(1)deal with意为“处理；对待；对付、论述或谈论(某问题)”，其中的deal为不及物动词，常与疑问词how连用。

　　(2)do with中的do为及物动词，表示“怎么处理、对待”时，与疑问词what连用。与否定副词连用时，意为“容许；容忍”。

　　①I don't know what they will do_with the problem.

　　我不知道他们将如何处理这个问题。

　　②This is a book dealing_with Asian problems.

　　这是一本论述亚洲问题的书。

　　[运用提升]

　　—How do you________a disagreement between the company and its customers?

　　—The key to solving the problem is to meet the demand made by the customers.

　　A．make do with

　　B．do with

　　C．handle with

　　D．deal with

　　答案：D　句意：“你怎样解决公司与它的顾客之间的分歧？”“解决问题的关键是满足顾客的要求。”make do with“凑合，将就”；handle为及物动词，后无需加介词；do with与deal with都有“处理，解决，对付”的意思，但do with常与what搭配；deal with常与how搭配。

　　7．watch over 看守；监视；照看

　　观察下列句子，了解watch over的不同含义：

　　①The three prisoners have been watched_over by the police.(看守)

　　②They have been watching_over the enemy closely.(监视)

　　③Will you please watch_over my baby when I am in town？(照看)

　　[归纳拓展]

　　watch out(for) 留神；提防

　　keep(a)watch 值班；守望

　　on/off watch 在/不在值班

　　be under close watch 被严密监视

　　①Watch_out! There is a car coming.

　　小心！有辆小汽车来了。

　　②The soldier kept_watch at the gate.

　　士兵在大门口值勤。

　　点拨：表示“小心”的短语，我们还学过be careful, look out, take care, beware of等。

　　8．I developed very slowly and it took nearly two hundred years before I was built as an analytical machine by Charles Babbage.

　　我发展很慢，差不多到了两百年之后，查尔斯·巴比奇才将我制成了一台分析机。

　　(1)“It＋be＋时间段＋before...”句型意为“过一段时间后才/就……”；若主语为将来时态，从句则用一般现在时态；其主句是一般过去时态或过去完成时态，则从句用一般过去时。

　　①It won't be long before such things happen again.

　　过不了多久就样的事还会发生。

　　②It had been/was several days before the three missing tourists were found.

　　过去了几天才找到这三位失踪的游客。

　　点拨：before在引导时间状语从句时，除了译成“在……之前”之外，在不同的语境中还可译成“还没来得及……就……”或“趁着……还没有……就……”。

　　(2)“It＋be＋时间段＋since...”句型意为“自从……以来已经有多长时间了”。主句常用一般现在时或现在完成时，从句用一般过去时。如果since从句中的谓语动词为非延续性动词，则译为“自从……以来多长时间了”，如下文例①；如果从句中的谓语动词为延续性动词，则译为“不做……多长时间了”，如下文例②。

　　①She has rung me once since she left.

　　自从她走后来过一次电话。

　　②It has been many years since they lived in the town.

　　他们已经有多年不在镇上住了。

　　辨析：时间状语从句与强调句

　　在“It be＋时间点＋that/when...”句型中，如果将it，be和连词去掉后句子仍然完整，说明是强调句，应用that；如果去掉这些成分之后句子不完整，应用连词when引导时间状语从句。

　　①It was nearly 8 o'clock when I returned home from the concert last night.(时间状语从句)

　　昨天晚上我听完音乐会回家时已经是将近8点钟了。

　　②It was at 3 o'clock that the professor started his lecture.(强调句型)

　　教授是在3点钟开始他的讲座的。

　　[运用提升]

　　(1)We had to be patient because it________some time ________we got the full results.

　　A．has been; since

　　B．had been; until

　　C．was; after

　　D．would be; before

　　答案：D　在“it＋be＋一段时间＋before/after/since＋从句”句型中，before从句中的动作经过一段时间后才会实现；after从句中的动作发生后已经过去了一段时间；since从句中的动作完成后到现在已经有一段时间了。句意：我们必须得耐心点，因为要得到完整的结果还得需要一段时间。结合题意可知，答案为D。

　　(2)(2011·福建，33)It was April 29,2011______Prince William and Kate Middleton walked into the palace hall of the wedding ceremony.

　　A．that

　　B．when

　　C．since

　　D．before

　　答案：B　本题考查状语从句。句意：2011年4月29日，威廉王子与凯特·米德尔顿步入婚礼殿堂。分析句子结构可知，连词when引导的为时间状语从句。

　　(3)(2011·四川，6)As is reported, it is 100 years ________ Qinghua University was founded.

　　A．when

　　B．before

　　C．after

　　D．since

　　答案：D　本题考查状语从句。句意：正如报道的那样，清华大学建校100周年了。从句中动词的时态“was founded”来看，since一词最合适。

　　9．And my memory became so large that even I couldn't believe it!

　　我的存储量变得如此之大，连我自己都不能相信！

　　so/such...that引导结果状语从句，意为“如此……以至于”。

　　[归纳拓展]

　　(1)so...that...句型的常见形式：

　　so＋adj./adv.＋that...

　　so＋adj.＋a/an＋可数名词单数＋that...

　　so＋many/few/much/little＋n.＋that...

　　(该结构中的so是副词，用法等同于“as...as”结构中的第一个as，引导感叹句的how及“too...to”结构中的too。)

　　(2)such...that句型的常见形式：

　　such a/an＋adj.＋可数名词单数＋that...

　　such＋adj.＋可数名词复数/不可数名词＋that

　　(该结构中的such是形容词，用法相当于引导感叹句的what。)

　　(3)so that以便于(引导目的状语从句)；结果(引导结果状语从句)。

　　It was so_hot_a_day_that nobody wanted to do anything.

　　(＝It was such_a_hot_day_that nobody wanted to do anything.)

　　天气如此热，谁也不想干活。

　　I made so_many_mistakes in the composition that the teacher criticized me.

　　我的作文中出了许多错误，老师批评了我。

　　③He hurried up so_that he could catch the train.

　　他匆匆赶路为的是赶上火车。

　　So_fast_did_the_teacher_speak_that I couldn't follow him.

　　那个老师说得太快，我听不懂。

　　点拨：当so.../such...放于句首时，主句应用部分倒装。

　　[运用提升]

　　(1)(2010·全国，26)I have seldom seen my mother ________ pleased with my progress as she is now.

　　A．so

　　B．very

　　C．too

　　D．rather

　　答案：A　句意：我很少看到妈妈像现在这样对我的进步感到满意。该题考查not as/so...as...结构。

　　(2)(2009·山东)So sudden________that the enemy had no time to escape.

　　A．did the attack

　　B．the attack did

　　C．was the attack

　　D．the attack was

　　答案：C　本题考查倒装。在so...that...，such...that...的句子结构中，若so, such 和与其所修饰的词置于句首，主句部分倒装，又因为sudden是形容词，作表语，需要将系动词提前，所以选C。

　　(3)(2009·辽宁)________is the power of TV that it can make a person suddenly famous.

　　A．Such

　　B．This

　　C．That

　　D．So

　　答案：A　考查 such...that引导的结果状语从句。that后跟了一个完整句子说明是关联词语，前面应是so或such,

　　因为so修饰形容词、副词，不能作主语，因而用such作主语。句意：电视具有这样的力量，它能够使人突然出名。
