“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.

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]

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。

(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]
用signal, symbol, sign和mark填空。

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
