The monkey, like man, has an opposable thumb (大拇指) —that is, it can place its thumb opposite its other fingers. By pressing its first finger against its thumb a monkey can pick up things as tiny as a flea (跳蚤). Because other animals lack this kind of thumb, it is difficult for them to pick up small things and carry them. The monkey’s ability to grasp rice with its paw often leads to its capture. Hunters put some rice inside a coconut, leaving a hole in the shell of the nut. The monkey has no trouble sliding its paw through the hole. But it can’t draw the paw out while it is holding the rice with its paw. Since it isoften too stupid or greedy to open its hand, the monkey is unable to free itself from this simple trap (圈套).11. According to the passage, not many animals have ______.A. handsB. paws with thumbsC. paws without nailsD. paws12. An opposable thumb is a thumb that can ______.A. pick up thingsB. be placed against the other fingersC. press against the opposite thumbD. press against anything13.

Lesson 79 By air乘飞机Why did the plane turn back?I used to travel by air a great deal when I was a boy. My parents used to live in South America and I used to fly there from Europe in the holidays. A flight attendant would take charge of me and I never had an unpleasant experience. I am used to traveling by air and only on one occasion have I ever felt frightened. After taking off, we were flying low over the city and slowly gaining height, when the plane suddenly turned round and flew back to the airport. While we were waiting to land, a flight attendant told us to keep calm and to get off the plane quietly as soon as it had touched down. Everybody on board was worried and we were curious to find out what had happened. Later we learnt that there was a very important person on board. The police had been told that a bomb had been planted on the plane. After we had landed, the plane was searched thoroughly. Fortunately, nothing was found and five hours later we were able to take off again.参考译文我在幼年的时候，曾多次乘飞机旅行。
新概念英语第二册79课作文答案
新概念英语第二册79课作文答案OK, here's an example of an essay for Lesson 79 in New Concept English, Book 2, adhering to the guidelines you've provided:Well, I've been meaning to tell you about my latest adventure. It was a real blast! I decided to take a spontaneous trip to the countryside, just to get away from the hustle and bustle of the city. You know, sometimes you just need to breathe in some fresh air.Oh, and the views were breathtaking! Rolling hills,lush green fields, and that crisp country air. It was likea whole new world. I even spotted a few cows grazing peacefully in the distance. It reminded me of simpler times, when life was slower and more relaxed.And then, there was this old-fashioned cafe I stumbled upon. It was a bit off the beaten track, but the coffee was divine! The owner was so friendly and chatty, we got into agreat conversation about local history and traditions. It was such a pleasant surprise.On my way back, I stopped by a little market. You should have seen the variety of fruits and vegetables! I bought some local honey and a jar of homemade jam. The flavors were so intense, I could almost taste the sunshine.All in all, it was a day well spent. I feel refreshed and rejuvenated. I'm definitely going to make it a habit to take more of these little escapes. Life is too short to be stuck in a rut, after all.。

根据课文第11行，只有d. there was fear of an explosion (爆炸)是课文所暗示的情况，并能说明飞机返回的原因，而其他3个选择虽然都是课文所提及的内容，但不是飞机返
回的原因，所以应该选d.
3. c
a. use to travel 语法错误；
b. used to travel 指过去经常性的动作，而本句的时间状语是today,表示现在，因此不能用used to; d. am used to traveling(习惯于旅行)可以表示现在的情况，但与前一句没有逻辑关系，不符合题目意思；只有
c. travel 是一般现在时，可以表示现在经常性动作，最符合题目意思和语法，所以选c.
4. c
本句需要一个同前一句的a great deal(很多)意义相同的词或词组. a. very many(非常多)只能修饰可数名词,而不能修饰动词. b. a great number(很多)也不能修饰动词. d. lots(很多)常跟of 连用,修饰可数名词.这3个选择都不能替换前一句的a great deal,只有c. a lot 与a great deal 意思等同,并且可以修饰动词.
5. a
本句是一个疑问句，需要一个适合的表示时间的疑问词，以便使它同后面的回答Since I was a boy(自从我幼年时)的意义相吻合。
c. for when 不合乎语法，询问时间只需要用when就可以了。
d. how much (多少)不能针对时间提问，a. since when(自从何时起)和b. when (何时)都是对时间的提问，但a 比b 问的更具体，所以选a.
6. d
本句需要选一个能同the holidays(假期)搭配的介词，使句子的意思完整，a. on 不符合习惯用法，可以是on (one's) holiday (在休假中，在度假), b. to 意思不通，c. at 意思也不通，只有d. during 最合乎语法，意思也通顺，所以选d
7. b
a. frightening 前面没有冠词，不合乎语法；c. the frightening 也不够正确，因为它所修饰的名词后面没有定语从句或其他限定成分，没必要用定冠词；d. one frightening 和
b. a frightening 意义相同，也都合乎语法；但是d.强调数量是一个而不是两个或几个，而b. 泛指“一个”，是与特指相对的. b. 比d 更合乎习惯用法，所以选b.
8. a
只有a. trip才能同前一句中的动词went on a 搭配构成固定短语went on a trip(去旅行),而其他3个选择b. travel, c. way, d. distance 都不能和went on 搭配构成惯用法,所以选a.
9. d
该句需要一个同前一句的take charge of(照管,负责)含义相接近的词,才能使两个句子意思相吻合. a. dutiful(尽职的,尽责任的), b. commanding(指挥的,有控制力的), c. charging(充填的,充电的), d. responsible(负责的,对……有责任的)中，只有d 与take charge of 的含义最接近，所以选d.
10. a
该句需要一个同前一句的be used to(习惯于)含义相接近的词,才能使两个句子意思相吻合. a. accustomed(习惯的，适应了的，一般做表语。
) b. habitual (习惯性的，通常的，常做定语) ，c. customary (习惯上的，合乎习俗的，惯例的)，d. inhabited(有人居住的)中，只有a 与be used to 的含义相同，并且它后面也可以跟介词to引导的短语，所以选a.
11. a
该句需要选一个与前一句中的形容词calm (镇定的，冷静的)含义相反的形容词，才能使两句的意义相同。
a. nervous (神经紧张的，情绪不安的)；b. angry (生气的，愤怒的)；
c. irritated (被激怒的，生气的) 和
d. annoyed (使恼怒，使生气)中，只有a. 是calm 的
反义词，所以选a.
12. c
该句需要选一个与前一句中的were curious to find out (急于想发现)的含义相同的词组。
a. were strange (陌生的，不平常的，奇怪的，古怪的)；
b. were odd (奇特的，古怪的)；
c. wanted to know (想知道)；
d. were peculiar (奇怪的，乖癖的，特别的)中，只有c. 最接近were curious to find out 的含义，而其他3个选择意思比较一致，都不符合题目意思，所以只能选c.。
