Computers
“種菜”小心栽進(jìn)廣告陷阱
Here's an idyllic(和平美麗的)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 computer-generated 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．a(chǎn)nyhow adv. 無論如何；即使如此
觀察下面句子，體會(huì)anyhow的不同意義：
Anyhow I must get all the work done before Monday.(無論如何)
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.(隨便地，胡亂地)
點(diǎn)撥：(1)anyhow用于表達(dá)“無論如何，不管怎樣，即使如此”時(shí)可與anyway互換，常用于讓步狀語，位于句中；其前常有but，或者也可在句末。
(2)表示“況且，更何況，再說，至少”時(shí)，anyhow與anyway都用作狀語，用于對(duì)前面的話作補(bǔ)充，給出一個(gè)更充分的令人信服的理由。
(3)作“隨意地，雜亂地，無辜地”講時(shí)，不能用anyway而只能用anyhow。
[歸納拓展]
somehow表示“以某種方式，不知怎么地”，與anyhow意義不同；
somewhat adv. 稍微；有些，常用來修飾形容詞或副詞。
Somehow,_he lost his way in the fog.
不知道怎么地，他在大霧中迷路了。
He was somewhat surprised to see his father sitting at the back of the classroom.
看到父親坐在教室后面，他感到有些驚訝。
[運(yùn)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：我們要成功地改變法律的可能性不大，但不管怎樣(盡管如此)，嘗試還是很重要的。anyhow“不管怎樣，盡管如此”；somewhat“有點(diǎn)，有幾分”；anywhere“不管哪里，在任何地方”。
2．signal vi. & vt. 發(fā)信號(hào) n. 信號(hào)
He signalled(to)the waiter for the bill.
他示意服務(wù)員結(jié)賬。
[歸納拓展]
(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 危險(xiǎn)/警告/停車信號(hào)
traffic signals 交通信號(hào)燈
辨析：symbol, signal, sign, mark
(1)symbol 指符號(hào)、象征、標(biāo)志等。
(2)signal 指信號(hào)、暗號(hào)或警告等。
(3)sign 表示“記號(hào)，符號(hào)”時(shí)，同“symbol”。表示“告示，指示牌”時(shí)，側(cè)重指用圖畫、文字表達(dá)的告示、圖示，此外還可以理解為“跡象，征兆”。
(4)mark普通用詞，含義廣泛。 既可指為便于辨認(rèn)而有意做的標(biāo)記，又可指自然形成的標(biāo)記或有別于其他事物的特征。
①Red is a symbol of danger.
紅色是危險(xiǎn)的象征。
②Dark clouds are usually a sign of rain.

答案：(1)symbol (2)sign (3)mark (4)sign (5)sign
(6)marks (7)signal
3．a(chǎn)rise vi. 出現(xiàn)；發(fā)生；起床，起身；上升
觀察句子，體會(huì)arise的不同詞義：
①Seeing his mother return home, the boy arose from his chair immediately.(起身)
②New problems will arise one after another in future.(出現(xiàn))
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)……產(chǎn)生]
[歸納拓展]
(1)arise表示“出現(xiàn)，發(fā)生”之意時(shí)，其主語多為problem, argument, quarrel, danger, movement, question等抽象名詞，多指不好的事情發(fā)生或出現(xiàn)。
(2)arise from/out of由……而引起；由……而產(chǎn)生；從……中產(chǎn)生
辨析：arise, arouse, rise, raise
