Key: 1. issues / problems 2. prob-lems 3. issue 4. problem 5. problems 6. problem

【简析】issue意为“议题;争论点”,强调急需讨论研究、争论、争辩(如1和3)。problem 意为“难题;困难”,强调有难度,需要考虑、关注及解决(如1,2和4);也作“(需要做的)习题或(数学)题”解(如5);还可作“ 构成问题的人;引起麻烦的人”解(如6)。

Key: 1. was wiped off 2. wipe away 3. wiped away 4. wipe out 5. was wiped out 6. wipe off / be wiped away

【简析】wipe away作“擦掉;清除掉”解,运用较为广泛(如2)。wipe off也可作“擦掉;抹掉”解,但wipe off可用作不及物动词(如6),也可把off用作介词(如1)。wipe out 意为“消灭;去除(多为某种不好的东西,如4);擦洗......的内部”,也可作“使精疲力竭”解(如5)。

三、defend; protect

1. All too often, global development means that rich people get richer while the poor get poorer. 全球发展常常意味着富人更富,穷人更穷。

1) all too... 是习惯用语,意为“实在太......”,常用于all too often(时常),all too soon(太快)等固定搭配中。例如:

All too often, Tom came to ask me for money. 汤姆经常来向我要钱。

2) mean作动词用时,后面常接to do sth.或V-ing形式。一般来说,mean to do sth.多表示“打算做某事”,而mean doing sth. 则大多表示“意味着做某事”。当然,有时为了结构的对应关系,mean to do sth.也可表示“意味着做某事”,但mean doing sth.一般不表示企图或打算做某事。例如:

Missing the bus means waiting for one more hour. 错过了这班公共汽车意味着要再等一个小时。

3. Among the speakers was China's then Premier Zhu Rongji, who stressed the need for equality and fairness in the world. 演讲者中有中国当时的总理朱镕基,他强调世界范围内的平等与公正。

1) 以上句子是一个完全倒装结构。引起倒装的原因是由于表示范围的

Among the speakers位于句首。

2) 句中的stress是动词,意为”强调“。例如:

The English teacher stressed the importance of reading aloud. 英语老师强调了朗读的重要性。

作及物动词时,stress还可表示”加压力于......;使紧张“。例如:

The weight of snow stressed the roof to the point of collapsing. 积雪的重量压得屋顶快要塌了。

4. And if poverty is less of a problem and people are better educated, there is a good chance that we will see less violence and fewer wars. 如果贫困的问题得到改善,人们的教育程度得以提高,就有可能会减少暴力和战争。

There is a chance (that)... 句型中的chance表示”可能性“,相当于possibility。例如:

There is a chance that the sick child will get well. 那个生病的孩子有可能会康复。

由chance构成的常用短语有by chance,意为”偶然地;意外地“。例如:

I met her quite by chance. 我遇见她完全是偶然的。

篇2:《走一步,再走一步》重难点讲析

【重难点语句】

1、从课文内容看,标题“走一步,再走一步”是什么意思。

〖解析〗 题目的开头一般指明了我 们回答问题的思路和方向。首先要默读 全文,整体感知课文,明确本文写的是一件什么事情,再结合事情的经过,尤其是脱险的过程,联系结尾的议论语言,便不难理解文章题目的含义。

〖参考答案〗 无论怎样的危险和困难,只要把它分解开来,分解为一小步一小步,困难 就不大了。“你只要想着你是在走一小步。”“走了这一步再走下一步”,一步一步走下去,有天大的困难也可以闯过来。

2、石架大约7米高,扛梯子把孩子抱下来要保险得多,也简单得多,父亲为什么不这样做?他的办法有什么普遍意义?

〖解析〗 这要联系父亲的话语来分析,才能理解父亲这样做 的意图。

〖参考答案〗 父亲这样做,目的是让孩子经受一次历练,增长勇气和经验。他的办法告诉人们,对孩子不要溺爱,要科学地训练孩子,使之自立自强。作为家长,当孩子遇到困难和挫折时,要给以指导、鼓励,不能包办代替,路要让孩子自己走,在自己走的过程中不断 地成长、成熟起来。

【重难点讲解】

1、“感到前途茫茫”意思是不知道怎样才能抵达我要到的地方,困难重重,举步维艰。

2、“我提醒自己”,……“ 直到抵达我所要到的地方。”这段话点明了全文的主旨,也蕴含着战胜一切艰难险阻的人生哲理:在人生道路上,不管面对怎样的艰难险阻,只要把大困难分解为小困难,一个一个地认真地解决小困难,终将战胜巨大 的困难,赢得最后的胜利。

作者小时候“在那座小悬崖上所学到的经验”,这是战胜一切艰难险阻的人生经验,即使有天大的危险和困难,只要把它分解开来,分解为一小步一小步,困难就不大了。“你只要想着你是在走 一小步”,“走了这一步再走下一步”,一步一步走下去,无论有多大的困难也可以闯过来。关键是化整为零 。大困难是由小困难组成的,小困难是不难战胜的,一步一步战胜了小困难,最后战胜了大困难。重要的是走好每一步,一步一步坚持不懈地走下去。这种人生经验,给人以战胜一切艰难险阻的信心。“我”爬到岩石架上,上不去,下不来,陷于绝望、恐惧。听了父亲的话,觉得一小步,“似乎能办得到”,第一步成功,“顿时有了信心”,第二步成功,“信心大增”。这个 经验,使他在今后的人生道路上,能对付一切。

《走一步,再走一步》问题探究

1、“我们”为什么想到爬悬崖?

一是天气闷热,想爬到悬崖上去凉爽凉爽;二是好奇心的驱使,想去尝试不曾经历过的”新花样“。

2、那座悬崖只有二十米高,为什么在“我”眼中“却是高不可攀得险峰”?

因为“我”八年来一直有病,在心中牢记母亲叫我不要冒险的训诫,从来没有爬过峭壁,再加上壁面有许多凸出来的岩石、崩土、蓬乱的灌木。恐惧心一下占了上风,所以只有二十米高的悬崖变成“我”眼中的险峰。

3、在爬悬崖得过程中,面对 “ 高不可攀得险峰” ,“我”的神情心理如何?(用文中语句回答)

“全身颤抖, 冷汗直冒” ,“我的心在瘦骨嶙峋的胸腔里冬冬直跳。 ”,“心惊肉跳……吓得几乎晕倒” 。

4、“我”是怎样爬下山崖的?

“我”是再父亲的帮助、引导下 爬下山崖的。具体的是:第一步,安慰“我” ,给我一个希望,可以回家吃饭了;第二步,引导“我”,化解困难,让“我”只走好眼前的一步;第三步,不断鼓励“我”,指引“我”方向。

5、父亲引导“我”走下悬崖时,说的哪三句话最为关键,使“我”从中体会到人生的哲理?将这三句话写在横线上。

⑴ 不要想着距离有多远。

⑵ 你只要想着你是在走一小步。

⑶ 不要担心下一步。

惜缘

篇3:高二第十单元重、难点问答

作者:赵忠西

1. How does nature form a danger to people in the world and how can science help reduce that threat?

[问] reduce的主要用法有哪些?

[答] reduce意为”把......减少“、”降低(价格)“、”缩小(程度、尺寸等)“,是及物动词。例如:

The bike was reduced from 300 yuan to 200 yuan. 这辆自行车的价格从300元降到200元。

You must reduce your expenses. 你必须减少你的开支。

reduce还表示”使成为“、”使处于(某种状态)“,多用于被动语态,且与介词to连用。例如:

The house was reduced to ashes. 房子被烧成灰烬。

In the past, she was reduced to begging. 在过去,她被逼得去讨饭。

2. Some people got into a total panic, when the typhoon pulled the roofs off their houses and cars went up in the air.

[问] get into a panic表示什么意思?

[答] get into a panic意为”进入恐慌状态“,是固定搭配,可与about连用,引出原因。例如:

They got into a panic about the fire in the building. 他们因大楼起火而变得慌乱起来。

He got into a panic when he thought he'd forgotten the passport. 他想起忘了带护照时,惊慌起来。

3. The sight of it awoke the scientist in my uncle to go and see it from closer at hand.

[问] at hand能用by hand替代吗?

We live close at hand. 我们住在附近。

Fortunately there was someone at hand. 幸好附近有人。

This desk was made by hand. 这张桌子是手工制作的。

at hand还表示”在手边“、”即将来到“,作状语或表语。例如:

4. With a tearing crash, tons of water fell upon the deck, as though the ship passed under a waterfall.

[问] as though的主要用法是什么?

[答] as though表示”好像“、”仿佛“,是连词,引导方式状语从句或表语从句。通常用来表示主观想象或夸大性的比喻,从句谓语动词常用虚拟语气。该用法在本报第14期《貌似错误却有理,别有用意表虚拟》中已讲过,不再赘述。

as though引导表语从句时,若从句中的情况发生的可能性很大,从句谓语动词用陈述语气。例如:

The meat tastes as though it has already gone bad. 肉尝起来好像已经坏了。

It looks as though we'll have to walk.看来我们得步行了。

1. You mean it looks strange! I’ll tell you something that does sound strange.你是说这看上去奇怪!我要告诉你听起来确实奇怪的事。

这两句话中分别用到了连系动词look(看上去是)和sound(听起来是)。类似的连系动词还有:smell(闻上去是),feel(摸起来), taste(尝起来)。使用这类连系动词时,不要用进行时和被动语态。如:

How sweet the music sounds!这音乐听上去多美!

The water feels cold.水摸起来很凉。

They taste like carrots.它们的味道像胡萝卜。

另外,第二句中的does用以强调,表示“确实”、“的确”等,以加强语气。如:

He did attend the meeting early then.他当时的确很早就到会了。

Do come on time.务必按时光临。

I do want to be sure. Do be silent!我确实想肯定。安静!

2. In the north, the winters are long and hard, with snow for six months of the year.北方,冬天漫长而严酷,一年有半年的积雪。

hard在此表示“严酷的”、“艰难的”。该词的另一些形容词词义需要弄清楚。如:

坚硬的adj.

Skate on hard enough ice.在足够硬的冰上溜冰。

The snow has frozen hard on the road.路上的雪已经冻得很硬了。

困难的,艰难的hard questions难题;a hard assignment.困难的任务

严厉的.,苛刻的;无情的

a hard master严师;a hard heart铁石心肠;a hard customer挑剔的顾客

Don\\'t be too hard on the boy.不要对这个小男孩太苛刻了。
