thought of as

看到一句話用到"thought of as"
"Software is thought of as a science",Bahat says.
Bahat說"軟體工程被認為是一門科學"（後文提出，也許是藝術）

我的疑問是：
如果是我寫這句話，我會寫成"thought as"....這樣是不是會有什麼問題？
"Software is thought as a science"

我另外在網路上看到一個技術學院考試的題目

1.He is ____ a child prodigy. (神童)
...(A) thought of as (B) thought as (C) considered as
參考答案是(A)"thought of as"

should "竟然"

SHOULD

"It is strange that he should not be here on time  as usual this time"

"好奇怪，他這次竟然不像平常一樣準時"

如果說想要表達的意思是

"好奇怪，他這次竟然準時到"(例如我故意放路障陷害他遲到，或是他平就習慣遲到)可以這樣寫嗎?

"It is strange that he should be here on time as usual this time"

一些that子句的問題

就我目前的了解，

1.that不能接非限定子句

2.所謂非限定子句其作用為"補充說明"

"My brother ,who lives in Taipei, will come back next week"

"我哥哥，住台北，下星期會回來"

（而非"我住台北的哥哥下星期會回來"）

3.非限定用法會伴隨","出現在關係子句之前

疑問：

Q1: "It is certain that the earth is round."

這個"that"的先行詞是"certain",而非整個主要子句?

Q2:有沒有先行詞是句子但又是非限定用法的時候？

it's billed as the largest in the world

it's billed as the largest in the world, with thousands of scooter enthusiasts descending on the island from all over the world. There, I'd join in with the rideouts and the festivities and chat to enthusiasts about their pride and joy.

前半段我大該看得懂

"這個活動以全球最大為號招（最大的速可達嘉年華），聚集了全世界的速克達愛好者"

後半段用猜的

"我參加了那些活動(rideout/festivities)並和其他愛好者聊聊他們的pride和joy"

Q1:那個"descending"在此處的意思？
雖然用前後文可以推出也許有聚集的意思...但查了一下字典找不太到這個用法

Q2: "I'd join in with"的文法看不懂
我一直找不到had+原形動詞的用法

in which

"Many Indian children have no house in which they can live"

是否可寫成

"Many Indian children have no house which they can live in"
或是

"Many Indian children have no house where they can live"
???

Robertoson began

"Robertson began by conceding that economics,concerned as it is with the desire for gain,does not deal with the noblest human motives"

這個句子我一直無法看懂其含意及結構

幾個疑問
1."econamics"前面的"that"是關係代名詞嗎？
所以後面的子句是"economics,concerned as it is with the desire for gain"嗎？

2."economics" 後面為何有個逗點?

3."with"在這裡的用法

由於文章內容無法剪下貼上，所以如果有需要，我再key in前後文

could的用法

看到一段標題

"Microsoft Office for iOS, Android could debut early next year""A version of Office for the iPhone, iPad, and Android devices will launch in early 2013, according to the Verge."

雖然原文標題我大概看得懂是
"iOS及Android版本的 Office 可能明年初會上市"

原文:
http://news.cnet.com/8301-10805_3-57546259-75/microsoft-office-for-ios-android-could-debut-early-next-year/


因為最近看到有關could的用法

1.can 的過去式

2.禮貌的請求
"could you operate this washing machine for me?"

3.和現在或未來事實相反
"If I had enough money, I could buy  that car now."


以前我如果看到could就很單純的翻譯成"可能"....但自從學了假設語氣後,每回看到could/should...這類東西腦袋都會卡住

另外我也看過有書上寫
可能性的強度 =>"can>may>could>might"

如果could都已經被認定為是"和現在或未來事實相反" 那 could怎麼還會比might排序在前面??

我目前的猜測是=>是否could出現在 "if"子句才是 "和現在或未來事實相反"?????
