The long trunk of an elephant is a wonderful example of skill. The neck of four-footed animals is usually long, to have them reach their food without difficulty, but the elephant has a short neck, to make him more easily support the weight of his huge head and heavy teeth. His long trunk lets him get his food easily.
The trunk of an elephant is to him what the neck is to other animals. It is also a nose to him, for at the end of it there is an empty place like a cup, and in the bottom of the cup are two holes, and the animal smells and breathes through them. It is an arm and a hand too, so that it has been said that the elephant carries his nose in his hand, and it might also have been said that he breathes by his hand.
At the end of the trunk, there is a strange part, about five inches long, which forms a finger. With this finger the animal can pick up the smallest piece of money from the ground, and he has been taught to make marks like letters with a pen.
The trunk of a full-grown elephant is about eight feet long. The elephant has such great strength that he can knock down a man with it.

Unit3试题解析
1. 去散步go for a walk 或take a walk，walk前用a修饰。本题take the dog for a walk，译为“遛狗”。
2. “汤姆不在教室里，他现在在哪里？他去了图书馆。”
has gone to 去了某地（现在不在） has been to 去过某地（以前去过，现在在）
3. “我们学校学生的数量多于200。”
the number of+n.做主语时，谓语动词用三单。因为短语the number of 表示的是一个数量，就是一个数字，无论大小，都是单数。
4. “琳达，我们不能把车停在这里。” 所以后面标志上应该是“No Parking”禁止停车。
5. “饭做好了，吃吧！尝起来真美味，你能告诉我是怎么做的吗？”
“delicious”美味的是一种味道，选择“taste”尝起来。
6. “我喜欢这些照片，它们能使我想起住在乡下的生活。” remind sb. of sth.使某人想起某事
7. “我妹妹已经练习了很长时间网球，她打的和你一样好。”
as...as 和......一样......，这里说球打得好，修饰动词play，用副词well，所以为as well as。
8. “她过去常常乘公交车去学校，但是现在她习惯步行去学校。”
第一空 used to do sth. 过去常常做某事 第二空 be used to doing sth. 习惯于做某事
9. “许多野生动物处于危险中。对我们来说是时候做些我们能做的事情去保护它们了。”
in danger 处于危险中 on show 在展览 in order 按顺序 on duty 值日
10. “你能给我买些牛奶吗？抱歉，但我没有钱。”
第一空 疑问句语气委婉，希望得到肯定回答，用some。 第二空 否定句some变any。
11. “你必须得更仔细，避免犯你曾经犯过的错误。” avoid 动词，避免
12. “今天晚上我们学校将会有一场篮球赛。”
There be 句式将来时：There will be 或There is/are going to be。
注意：一定要避免错误选项There is going to have。
13. “当我们远离家的时候，我们必须照顾好我们自己。”
look after 照顾 look at 看 look for 寻找 look up 查阅
14. “既然你不跟我一起去电影院，那我就自己去吧。” since conj. 既然，由于，因为

17. “你可以拿两个玩具车中的任何一个，留下另一个给你的哥哥。”
either（两者）任何一个 neither两者都不 both（两者）都 none（三者及三者以上）都不
18. “她已经读过了这个故事，不是吗？”
根据read-read-read，可以判断，此处为过去分词。所以’s缩写为has的缩写，有助动词has，反义疑问句后面疑问部分就应该用助动词has，前面陈述部分是肯定，后面疑问部分就要用否定，所以为hasn’t。
19. “李明和他的同学经常在周末帮助老人。”
along with连接并列主语时，谓语动词与along with前面的主语保持一致。本题需与Li Ming保持一致，所以谓语动词用三单形式。
20. “妈妈，明天的计划是什么？ 如果不下雨，我们就去野营。”
if引导的条件状语从句，遵循“主将从现”原则。主句用将来时will go camping，从句应该用一般现在时，排除A，D。根据句意，应该是“不下雨”，所以答案为doesn’t rain。
单词拼写：
36. “这个女孩害怕老鼠。” mouse为可数名词，此处做“老鼠”讲，因此用复数mice。
37. “今天早上他把他的包放在桌上。” 通过this morning可知时态为一般过去时，lay 动词，放置，lay-laid-laid，所以答案为laid。
38. “她摇头说不。” and并列前后两个动作时态保持一致，根据后面said是过去时态，前面也应该用过去式，shake 动词，摇晃，shake-shook-shaken，所以答案为shook。
39. “保护环境是我们的责任。” protect the environment保护环境

48. have sth. done，使某事被做，填plant过去分词形式，planted。
49. “如果不是特别远，步行或骑车去上班。” 根据句意，应该用if。
50. “并且每次你避免开车，你就正在做一些有用的事情减少空气污染。” 不定代词something后加形容词，所以用helpful。

52. “水对生物来说是非常重要的。” 根据句意，填important。
53. “节水最简单的方式是在用完之后关掉水龙头。” turn off 关闭。
54. “当你去沙滩玩的时候，确保你没有到处扔废物。” make sure 确定，确保。
