答案解析：

6答案选A 她不如她朋友那么会说话，但她笔头功夫是相当不错的。as+形容词/副词+as表示平级比较，对比的两样事物处于同一级别，用于肯定句。so +形容词/副词+as表示平级比较，对比的两样事物处于同一级别，用于否定句。B跟.....一样经常....C很多的意思，D.....跟.....一样好。

We expect her to do the housework as well ____ after the children.

A、

as look

B、

as looking

C、

and look

D、

looking

正确答案： A 我的答案：A得分： 3.3分

答案解析：

答案选A 我们期望她做家务跟看孩子一样都干得不错。将做家务和看孩子两件事进行平级比较，两件事都能干好。as well as常用来连接两个并列的成分, 作“也, 还”解。它强调的是前一项, 后一项只是顺便提及。因此连接并列主语时, 谓语动词与前一项一致；这里as well as 两边用并列结构，这里是to do结构，后面的to可省略。故选A。

A、

正确答案： A 我的答案：B得分： 0.0分

答案解析：

答案选A 布莱克夫人的写作水平，即使没有超过，至少也跟他丈夫的水平一样好。这里考察的是as+形容词/副词+as表示平级比较，对比的两样事物处于同一级别，用于肯定句。C答案 so +形容词/副词+as表示平级比较，对比的两样事物处于同一级别，用于否定句，经常与not同时出现，形成not so +形容词/副词+a.....的表达式。

答案解析：

答案选D 他们日夜兼程全速赶路。by day and by night 或者 as well as by night ，as well as 相当于and 日日夜夜，夜以继日 A答案少了介词by；B答案多了as well as C as well多数用于句末，相当于too的用法。

Tom， ____ Jane and Rose， ____ going to the farm on foot.

A、

as long as；is

B、

as well as；are

C、

as long as；are

D、

as well as；is

正确答案： D 我的答案：D得分： 3.3分

答案解析：

答案选D 汤姆和简及露丝一样，也是走路去农场。侧重将汤姆去农场的形式与简及露丝一样，他也走路去农场，因此be动词形式由主语汤姆决定，用第三人称单数。A答案 as long as只要的意思，不符合题意。 B答案第二个答案are用错，本句主语是Tom，应该用be动词第三人称单数。

正确答案： A 我的答案：A得分： 3.3分

答案解析：

Saving the date

1 Every day I anxiously wait for you to get to class. I can't wait for us to smile at each other and say good morning. When you arrive only seconds before the lecture commences, I'm indifferent to anything but your arrival. Instead of reviewing my lesson, I anticipate your footsteps and listen for your voice. Today is one of your late days, but I don't mind because after a month of denying the impulse to ask you out, today I'm feeling bold. Today I'm inclined to act.

2 I know dating has changed dramatically in recent years, and for many women, asking men out isn't daring. But because of my traditional upbringing, the simple notion of asking you out seems abnormal. Growing up, I heard the clear message: Men must take the initiative and make contact. They should call, ask and pay for the date. However, during my years at the university, I've learned otherwise. Many of my women friends have put a spark in their social lives by taking the initiative with men. My girlfriends reckon that it's essential for women to participate more actively in the dating process. "I can't be idle and wait," my former roommate once said. "Hard as it is, if I want to date, I have to ask guys out!"

3 More women are taking the initiative and invite men out, and many men say they view this new phenomenon with approval. They are relieved that dating no longer solely depends on their willingness and courage to take the first step. Then why am I so nervous?

4 I tell myself to relax since dating is more casual today. A college date means anything from studying together to simply having leisure time together like watching a film. Most of my peers prefer casual dating because it's cheaper and comfortable. Students have fewer anxiety attacks when they ask somebody to play tennis than when they plan a formal occasion.

5 As an added bonus, casual dating also encourages people to forge healthy friendships prior to starting romantic relationships. Young people can relax and get to know each other more easily this way. For example, my roommate and her boyfriend were friends for four months before their chemistry clicked. They went out often with a bunch of mutual friends. They alternated paying the dinner check. "He was like any other friend," my roommate said laughing. Another friend of mine believes casual dating improves people's social lives, allowing them to circulate in wider social circles. When she wants to let a guy know she is interested, she'll say, "Hey, let's go get a yogurt." or "How about a cup of tea?"

6 Who pays for it? It's not as easy as it used to be because the traditional rules of courtship are undergoing major changes. Preliminary statistics also affirm this. A plurality of young men say women should chip in and help pay after a few dates. An almost equal percentage of women offer to pay for themselves, even on a first date. But widespread confusion still exists. The new rules have yet to be clarified.

7 My own past dates have taught me some things. Either "going Dutch" or allowing my date to pay can be a definite challenge. One date whipped out his wallet on our first date before I could suggest otherwise. During an after-dinner walk, he proceeded to tell me he was romantically interested in me. After I explained I was more interested in friendship, he seemed unhappy. He explained that since I'd accepted his paying for my dinner, he'd assumed I was interested in romance. He seemed angry with himself for treating me. I regretted allowing him to.

8 Another date frowned when I hastily opened my purse, pulled out my wallet, and offered to go Dutch. I asked politely, "How much do I owe you?" He said, "Uh, uh, you really don't owe me anything, but if you insist …" He looked exceedingly embarrassed. To him, my gesture of offering to pay had conveyed a message of rejection.

9 Everyone seems confused as they try to clarify the new rules of dating. Who should ask whom out? Who should pay and when? So, while I do think dressing up and going out on traditional, formal dates is a blast, I thrive on casual dating because it has brought a valuable dimension to my social life. With casual dating, there's less pressure and more equality. I can give roses as well as receive them! Casual dating is worthwhile because it works.

10 So here I am, waiting. No magic formula guarantees he will say "yes". I just have to relax, be myself and ask him out in a no-nonsense manner.

11 He finally arrives. Sliding into his desk, he pats my shoulder and asks, "Hi, what's up?"

12 "Good morning," I answer cautiously. With a knot in the pit of my stomach, I conquer my fear and ask, "Hey, how about lunch after class on Friday?"

13 "You mean after the midterm?" he says with barely concealed enthusiasm. "I'd love to go to lunch with you."

14 Thrilled and smiling broadly, I confirm, "Well then, we'll save the date!" "Yes, we will!" he replies cheerfully.

六、高一语文书人教版必修2《祝福》课后练习题答案？

1、她一手提着竹篮，内中一个破碗，空的；一手拄着一支比她更长的竹竿，下端开了裂：她分明已经纯乎是一个乞丐了。

问题：这句话如改成“她一手提着竹篮，内中放着一个空的破碗，一手拄着一支比她更长的下端开了裂的竹竿：她分明已经纯乎是一个乞丐了”，表达效果有什么不同？

答：通过比较，我们发现，原文中把修饰语后置了，证明祥林嫂确实已经以乞讨为生，并且乞讨艰难，乞讨时间很长了。这种后置的写法增强了语言的表达效果。

2、有些老女人没有在街头听到她的话，便特意寻来，，要听她这一段悲惨的故事。直到她说到呜咽，他们也就一齐流下那停在眼角上的眼泪，叹息一番，满足的去了，一面还纷纷地评论着。

问题：“特意”“满足”表现了这些老女人怎样的心理？

答：这些老女人“特意“寻来，听祥林嫂悲惨的故事，并不是真心同情她，而是作为无聊生活的一种调剂。猎奇之后得到一种“满足”，以通过鉴赏他人的痛苦来填补自己精神上的空虚。

3、她未必知道她的悲哀经大家咀嚼鉴赏了许多天，早已成为渣滓，只值得厌烦和唾弃……

问题：说“大家咀嚼鉴赏”祥林嫂的悲哀，表达了作者怎样的思想感情？

答：表现了作者对民众冷漠麻木的心灵的批判和激愤之情。

4、“祥林嫂，你放着罢！我来摆。”四婶慌忙地说。

她讪讪的缩了手，又去取烛台。

“祥林嫂，你放着罢！我来拿。”四婶又慌忙地说。

她转了几个圆圈，终于没有事情做，只得疑惑地走开。

（捐了门槛后）

“你放着罢，祥林嫂！”四婶慌忙大声说。

她像是受了炮烙似的缩手，脸色同时变作灰黑，也不再去取烛台，只是失神的站着。

问题：①四婶前后两次不让祥林嫂动祭具，祥林嫂两次反应大不相同，为什么？②比较一下，“祥林嫂，你放着罢！”和“你放着罢，祥林嫂！”表达效果有什么不同？

答：①祥林嫂第一次感到“疑惑”，她并不明白自己的“罪过”；而第二次她已经捐了门槛，认为自己已经“赎罪”了，可以被“宽恕”了，可是四婶的断喝让她明白自己永远不能被这个冷漠的社会“接受”，她的精神崩溃了。②“祥林嫂，你放着罢！”和“你放着罢，祥林嫂！”两句话的语气很不一样，后者命令的意味更强烈，态度也更严厉。

B型：10台 B型：9台

方案三 A型：2台

B型：8台。
