要求:
请解释我的错误选项以及正解。对于修改病句,务必改正错误。要详细。最好可以用正解造个句子或举个例子。
谢谢!

括号为修改部分或选项
1. The annual National Concrete Competition attracts teams of engineering students (having designed)canoes that promote the versatility of concrete.
A. having designed
B. who have designed
C. for designing
D. to be designing
E. and they designed
我选D。答案B。
从Annual可以看出句子是 present tense,但是答案B怎么是past tense?

2. Reading stories aloud to young students is an effective way to help them learn new words, (also it can spark their interest in studying) literature.
A. as it is
B. words, and it can also spark their interest in studying
C. words that can also spark in them the interest to study
D. words, as well as it could spark their interest in studying
我选A。答案B。
Also不是conjunction,可以连接两个句子吗?而且B也没有体现出“也”这个意思。

题目3-8为修改病句
3. Because traffic was (unusually heavy), Jim arrived ten minutes late (for) his job interview even though he had (ran desperately) all the way (from) the bus stop. (No error)
答案C。我选了E no error.
过去完成时不是had done sth吗,哪里错了?

4. (As) adults, male golden silk spiders (live not) in webs of (their own) making but rather in webs (made) by female spiders. No error
我选A。答案E
As不是“作为”的意思吗,它这么说不是相当于说有的male spiders都是adults吗?

5. At a time (when) interest in 20th century classical music (seems) on the verge (to disappear), the avant-garde compositions of the 1960s and the 1970s (manage) to retain their popularity. No error
我选D。答案C
它明明说at a time,说明是过去发生的,但为什么选项B和D都是现在时?

6. Persistent use of antibacterial soaps in homes (both kills) (many innocuous) bacteria and (encourages) harmful ones to develop (even more resistant) strains. No error
我选A。答案E。
把both放在kill的前面不是说有两个主语会杀死细菌吗?比如说Me and Tom both like coffee.而句子想表达的不是这个意思

7. (Opposite to) most people I know, Annie, a good photographer (herself), actually (enjoys seeing) the photograph that her friends take (on their) vacations. No error
我选E。答案A。

8. (At) the reception (were) the (chattering) guests, the three-tiered cake, and the lively music that have become (characteristic) of many wedding celebrations. No error
我选D。答案E。
为什么不是characteristics of复数形式?
哦对了,问题2,B选项我多打了个also,应该是words, and it can spark their interest in studying. 问题2,A选项as it is是指照搬原文,而不是要你真的填as it is。

楼上大侠说得有理,有几个地方差点弄错呵呵.. 但还是有不一样的地方。

1.由句意可理解,划艇为"设计好了的",从这里你可以理解, 划艇是设计好了之后再拿过来的,也就是说动作已经完成了. 要用完成时
再看5个选项, 首先只有B项可以充当定语,是定语从句,然后他也表示完成,所以选B项.

2. also放在句首一般后接逗号, 也可不接, 相当于短语"at the same time", 原句的说法很口语化, 但是也是可以的,(其实现在英语中语法被淡化很严重)若是书面,一般是用答案的说法, also放在句中.只要有also这个词不就体现出也得意思了麽? also不能做连词用。

3. had done sth 是没错的,但是这题不是这里出错了, (这里我弄错了,楼上说得对)ran是过去式,run才是过去完成式,所以是had run.

4. (As 除了有"作为" 的意思,还有"像...一样"的意思, 这里的adults 应该理解成一般意义的"人". 句意为 "像人一样, 雄性金丝蛛..."),这是原来的,于语法确实没错。但仔细想想,“作为”也能理解得通,因为adults便是成年的人或动物,这里作为一个代词用,就是指代“成年金丝蛛”。

5. 这题不出意外的话应该是固定搭配错误 on the verge of + doing. 至于整个句子为什么用一般时态,是因为这是一个客观陈述, 在客观陈述时一般是用一般现在时, 第三人称要用人称单数.

6. both kills... and encourages....就看出来了吧。

7. opposite to 是"相对立,对立面的意思" 侧重对立,一般指观点想法. opposite 是"相反的"意思, 一般指物指人, 这里的主语是Annie,是个人所以直接用opposite.(用unlike其实更好)

8. 注意characteristic的位置, 他是在从句that have become characteristic of many wedding celebrations. 这个从句是the lively music 的同位语, 因此characteristic的主语就是the lively music,是单数,所以不使用复数。 (我觉得此处characteristic不应该作为表语,因为后面有of ,of 表示所属,如father of the daughter,所以这里应该理解为一名词。)

1. ing 的完成式不能做定语。
答案B。不是过去时,而是现在完成时

2. Reading stories aloud to young students is an effective way to help them learn new words, (also it can spark their interest in studying) literature.
换成 as it is literature 也讲不通。also 却不是连词。不能连接两个句子。and是并列连词

3. ran 是过去式, had run 才是过去完成时

4.As是“作为”的意思,指的是那些成年雄蜘蛛

5.既然两个地方的时态都是相同,那就不是时态的问题,应该是指:处于正在消失的边缘。用of disappearing.

6用both并非是要有两个主语。它的意思是:既会kill 又会encourage..

7. 应该是用unlike most people I know,

8. characteristic 在这里不是名词,是形容词,做系动词become 的表语。
