How was the plane able to clear the mountains?In 1929, three years after his flight over the North Pole, the American explorer, R.E. Byrd, successfully flew over the South Pole for the first time. Though, at first, Byrd and his men were able to take a great many photographs of the mountains that lay below, they soon ran into serious trouble. At one point, it seemed certain that their plane would crash. It could only get over the mountains if it rose to 10,000 feet. Byrd at once ordered his men to throw out two heavy food sacks. The plane was then able to rise and it cleared the mountains by 400 feet. Byrd now knew that he would be able to reach the South Pole which was 300 miles away, for there were no more mountains in sight. The aircraft was able to fly over the endless white plains without difficulty.参考译文美国探险家R.E. 伯德在飞越北极3年之后，于1929年第一次飞越了南极。

Standing by her chair, looking at the ink bottle, pens, and white paper, I decided that the act of writing must be the most wonderful thing in the world. Years later, during her final illness, mother kept different things for my sister and brother. "But the desk, "she'd said again, "it's for Elizabeth. "I never saw her angry, never saw her cry. I knew she loved me；she showed it in action. But as a young girl, I wanted heart-to-heart talks between mother and daughter.They never happened. And a gulf（分歧）opened between us. I was"too emotional（易动感情的）". But she lived"on the surface（表面）".As years passed I had my own family. I loved my mother and thanked her for our happy family. I wrote to her in careful words and asked her to let me know in any way she chose that she did forgive（原谅）me.I posted the letter and waited for her answer. None came.My hope turned to disappointment（失望）, then little interest and, finally, peace-it seemed that nothing happened. I couldn't be sure that the letter had even got to mother. I only knew that I had written it, and I could stop trying to make her into someone she was not.Now the present of her desk told, as she'd never been able to, that she was pleased that writing was my chosen work. I cleaned the desk carefully and found some papers inside-a photo of my father and a one-page letter, folded（折叠)and refolded many times.Give me an answer, my letter asks, in any way you choose. Mother, you always chose the act that speaks louder than words.1. The writer began to love her mother's desk _______.A. after Mother diedB. before she became a writerC. when she was a childD. when Mother gave it to her2. The passage shows thatA. mother was cold on the surface but kind in her heart to her daughterB. mother was too serious about everything her daughter had doneC. mother cared much about her daughter in wordsD. mother wrote to her daughter in careful words3. What did mother do with her daughter's letter asking forgiveness?A. She had never received the letter.B. For years, she often talked about the letter.C. She didn't forgive her daughter at all in all her life.D. She read the letter again and again till she died.4. What's the best title of the passage?A. My letter to MotherB. Mother and ChildrenC. My mother's DeskD. Talks between Mother and Me.四、七选五Holidays with friends can be great fun and a good way of getting to know each other better. Once you are on holiday, the trip can be full of fantastic memories if it’s planned correctly.● Choose a destination1 Going abroad will cost more but be a more exciting experience. While going to a different place in your own country can also be fun and will be cheaper.● Meet upEveryone will have their own idea of what they want the trip to be like, so meet up at a local café or restaurant, and share your ideas and concerns. 2 Don’t try to overpower them. Once you’ve all shared ideas, you’ll have a much better idea of how to start organizing the trip.● Look for accommodation3 When you are searching for a place to stay, read reviews and ratings (等级). Book it as soon as possible because leaving it too late is going to make things harder.● Book transportOnce you have accommodation, you’ll know the dates of your stay and will be able to book transport, e.g. coach, bus, train, airplane, etc. 4● Choose things you want to do thereWhen you are on your trip it will be more relaxed if you have a good idea of what kind of things you want to do. Research the area on the Internet and book some activities you want to join in. 5 Don’t book a load of things which you can’t afford.A. One person will naturally be the leader.B. Check out your passport.C. The first step is to work out where you want to go.D. Match the activities to your budget.E. Booking transport well in advanced lowers the cost dramatically so please do it soon.F. Make sure that the trip to a foreign country is too long or short.G. Find out your accommodation near to the place you want to visit.。
新概念英语第二册课后题答案详解Lesson43
新概念英语第二册课后题答案详解Lesson431. b根据课文第2-3行….R. E. Byrd, successfully flew over to the South Pole for the first time 能够判断出只有b. to fly over the South Pole 与事实相符，其他3个选择都不是R.E. Byrd 第一个做的事。
所以选b.2. b根据课文第7-8行Byrd at once ordered his men to throw out two heavy food sacks. The plane was then able to rise... 能够判断只有b. by making his plane lighter 与课文的实际情况相符。
其他3个选择都不是他成功的原因，所以应该选b.3. a这是一个一般过去时疑问几，需要选出准确的谓语动词。
a. lie (躺，处于某种状态，位于);b. lay (置，放)是lie的过去式;c. laid 是lay 的过去式和过去分词;d. lain 是 lie 的过去分词。
只有a. 最符合题目意思和语法。
因为在疑问句中已经有助动词Did,所以不能用过去式或过去分词，只能用动词原形。
b. 虽然也是动词原形，但不合乎题目意思，所以只能选a.4. a前一句It could only get over the mountains if it rose to 10,000 feet (只有在飞至10，000英尺的高度时，它才能飞过这些山头)表示对想像的条件所作出的推测，只有a. would succeed in getting(会成功)与前一句的含义比较吻合;b. got 是过去式，表示过去发生的情况;c. was able to 表示过去成功地完成; d. had got 表示过去早已经完成的动作。
这3个选择都与前一句含义不符，所以应该选a.5. d前一句中的was able to rise (得以上升)表示过去成功完成的事情。
新概念第二册43课详解
Lesson 43 Over the South Pole 飞越南极标题全称其实是：fly over the South Pole来比较一下over和above的一些区别：(1) over和above都可以表示“在…上方”。
两个物体是互不接触的。
比如：There is a picture above/over the fireplace.壁炉上有一张画。
Can you see the helicopter above/over the palace？你能看见宫殿上方的那架直升机吗？(2) over也可表示“在…之上”，两个物体互相接触，有on 和cover 的意思，而above 不能这样用He put his handkerchief over his face.他用手帕把脸蒙了起来。
（不能用above）She spread a cloth over the table.她把一块布铺在桌子上。
（不能用above）（3）如果要表示“越过”、“翻过”和“飞过”的意思，通常用over。
而above多用于表示一种静态的“在…上方”的意思。
If we can’t go over the mountain, we must go round it. 要是我们无法翻过这座山，我们只能绕山而行。
1. In 1929, three years after his flight over the North Pole, the American explorer, R.E. Byrd, successfully flew over the South Pole for the first time.这句话包含两个同位语。
three years after…为1929的同位语，作插入性的补充说明；R．E．Byrd 作the American explorer 的同位语。
for the first time:首次；第一次2. Though, at first, Byrd and his men were able to take a great many photographs of the mountains that lay below, they soon ran into serious trouble. 连词though引导的是让步状语从句，其含义为“虽然……”、“尽管……”。

句中知识点
1. In 1929, three years after his flight over the North Pole, the American explorer, R.E. Byrd, successfully flew over the South Pole for the first time.
如： My computer crashed again, and I had to reset it. ①crash 还可以表示电脑死机，
②at one point
在此处可以解释为“在有个地方”，通常的含义为“在某一时刻”（point指时间上 的某一点）
例如： At one point, he made up his mind to become a painter.

《新概念英语》同步讲义：第2册第43课
《新概念英语》同步讲义：第2册第43课【往期回顾】《新概念英语》同步讲义：第2册第42课【第2册第43课讲义】本课的重点语法是情态动词can与be able to的对比用法。
在一般现在时主动语态中表示“能、会”时，两者意义差别不大，可互换。
如：He can / is able to climb the mountain before schedule.但在以下几种情况中，两者不能换用：1、在词义上，can除可以表示“能、会”外，还可以表示“许可、允许”或可能性，而be able to则不行。
如：It can't be my son. He has gone to Xi'an. / Can I help you?2、can一般只有现在时和过去时两种时态形式，而be able to还可以用于将来时和完成时等其它时态时。
如：I'll be able to come back in five days. / She hasn't been able to finish thejob yet.3、be able to多表示有能力或技巧做某事，一般不用于指物；而can则既可表人也可表物的能力。
如：A tiger can run faster than a motorcycle.4、can可用于被动语态，而be able to则不能。
如：The house can't be destroyed in such a way.本课难点部分出现了有关介词at的常用短语。
如：1、at first（起初；首先）She'd liked him at first, but soon lost interest2、at last（最后；终于）Look! It's snowing.

passage
• In 1929, three years after his flight over the North Pole, the American explorer, R.E. Byrd, successfully flew over the South Pole for the first time. Though, at first, Byrd and his men were able to take a great many photographs of the mountains that lay below, they soon ran into serious trouble. At one point, it seemed certain that their plane would crash. It could only get over the mountains if it rose to 10,000 feet. Byrd at once ordered his men to throw out two heavy food sacks. The plane was then able to rise and it cleared the mountains by 400 feet. Byrd now knew that he would be able to reach the South Pole which was 300 miles away, for there were no more mountains in sight. The aircraft was able to fly over the endless white plains without difficulty.

新概念英语第二册课后练习题答案详解(第43课)
新概念英语第二册课后习题 Lesson 43
1. b
根据课文第2-3行….R. E. Byrd, successfully flew over to the South Pole for the first time 能够判断出只有b. to fly over the South Pole 与事实相符，其他3个选择都不是R.E. Byrd 第一个做的事。
所以选b.
2. b
根据课文第7-8行Byrd at once ordered his men to throw out two heavy food sacks. The plane was then able to rise... 能够判断只有b. by making his plane lighter 与课文的实际情况相符。
其他3个选择都不是他成功的原因，所以应该选b.
3. a
这是一个一般过去时疑问几，需要选出准确的谓语动词。
a. lie (躺，处于某种状态，位于);
b. lay (置，放)是lie的
过去式;c. laid 是lay 的过去式和过去分词;d. lain 是 lie 的过去分词。
只有a. 最符合题目意思和语法。
因为在疑问句中已经有助动词Did,所以不能用过去式或过去分词，只能用动词原形。
b. 虽然也是动词原形，但不合乎题目意思，所以只能选a.
4. a
前一句It could only get over the mountains if it rose to 10,000 feet (只有在飞至10，000英尺的高度时，它才能飞过这些山头)表示对想像的条件所作出的推测，只有a. would succeed in getting(会成功)与前一句的含义比较吻合;b. got 是过去式，表示过去发生的情况;c. was able to 表示过去成功地完成; d. had got 表
示过去早已经完成的动作。
这3个选择都与前一句含义不符，所以应
该选a.
5. d
前一句中的was able to rise (得以上升)表示过去成功完成的
事情。
a. could rise , b. might rise, c. might succeed in
rising 都表示对没发生的事情的推测，与前一句含义不符。
只有d. rose 表示过去发生的事情，与前一句时态相符。
所以选d.
6. d
前一句中的be able to 表示“能够”，需要选出与它含义相同
的词。
a. impossible(不可能的)和b. necessary(必要的) 都与be able to 意思不同;c. able(有水平的)不能单独作表语，要用be able to. 因为这个句子的主语是it, 代表前一句中that 引导的整个从句，所以不适合于这个句子。
只有d. possible(可能的，能办到的)与
able to 的含义相同，所以选d.
7. a
这是一个定语从句，需要选出准确的关系代词作主语。
c. it 和d. which it 都不合乎语法，都不能作关系代词;b. who 是作主语的
关系代词，但其先行词必须是人，而本句的先行词是the Pole. 只用a. which 最符合语法，它是关系代词，能够作主语指物，所以选a.
8. c
只有c. had 最符合题目意思.
a. ran after(追赶),
b. followed(跟随), d. ran(跑)这3个
选择都不合乎题目意思,意思不通.
9. c
只有c. immediately(立刻，马上)同前一句中的at once 是同义词，所以选c.
a. once(一次)，
b. soon(不久);d. quickly(快速地)这3个选择都与at once 的含义不太一样。
10. d
前一句The plane cleared the mountains 中的cleared 是"飞跃"的意思,需要选出同它含义相同的词. a. covered(覆盖), b. cleaned(弄干净), c. emptied(倒空)这3个选择都与cleared的意思不同. 只有d. flew over(飞过)与cleared 意义相同,所以选d.
11. a
本题目中，b. arrive(到达)是不及物动词，后面应该带介词at 才对。
c. reach at,
d. reach in 都不对，因为reach 当“到达”讲的时候是及物动词，后面不应带介词。
所以a. arrive at 是准确答案。
12. c
前一句的There were no more mountains in sight.(看不见高山)中的in sight 是“看得见”的意思，因为该句是否定句，所以是“不被看见”的意思，只有c. couldn't be seen(不能被看见)同前一句意思相符合。
a. were blind 是盲人
b. couldn't see 不能看见
d. were sightless 没视力的这3个选择都与前一句意思不符合。
