【考点一】感官动词 “see/hear” 的用法【考点二】方位介词 “in/on/under” 的用法区别
【考点三】“g” 和 “o” 发音规则 【考点四】动物叫声与动物的匹配
【考点一】感官动词 “see/hear” 的用法
核心含义:表示 “看到”“听到”,用于描述通过视觉和听觉感知到的事物。
1. 用法解析
1) 基本结构:can + see/hear + 名词(单数 / 复数),can 是情态动词,后接动词原形。
例:I can see a bird.(我能看到一只鸟。);She can hear a bee.(她能听到蜜蜂的嗡嗡声。)
2) 否定形式:can't + see/hear + 名词,can't 是 can not 的缩写。
例:I can't see a duck.(我看不到鸭子。);They can't hear a bird.(他们听不到鸟叫。)
3) 一般疑问句:Can you see/hear ...?(你能看到 / 听到…… 吗?),肯定回答用 “Yes, I can.”,否定回答用 “No, I can't.”。
例:—Can you see a butterfly?(你能看到蝴蝶吗?)—Yes, I can.(是的,我能。)
2. 注意事项
1) see 强调 “看到” 的结果,hear 强调 “听到” 的结果,后面直接接宾语,不需要加介词。
2) 当宾语是可数名词复数时,表示看到 / 听到多个事物;当宾语是可数名词单数时,前面通常加 a/an。
【大显身手】

( )1. I can ______ a bee on the flower.
A. see B. sees C. seeing D. to see

【考点二】方位介词 “in/on/under” 的用法区别
核心含义:表示事物的位置关系,区分 “在…… 里面”“在…… 上面”“在…… 下面”。
1. 用法解析
介词
含义
适用场景
例句
in
在…… 里面
表示在封闭空间或物体内部
The bird is in the tree.(鸟在树上)
on
在…… 上面
表示在物体表面,与物体接触
The butterfly is on the flower.(蝴蝶在花上。)
under
在…… 下面
表示在物体正下方
The cat is under the tree.(猫在树下。)
2. 注意事项
1) 表示 “在树上” 时,外来的事物(如鸟、风筝)用 in the tree;树本身生长的部分(如叶子、果实)用 on the tree。
例:There is a bird in the tree.(树上有一只鸟。);There are many apples on the tree.(树上有很多苹果。)
2) 方位介词后面接名词时,名词前通常需要加定冠词 the、形容词性物主代词或不定冠词 a/an。

2. The duck is ______ the pond.

5. The bird is ______ the tree.
二、句型转换。

2. The dog is under the tree.(改为否定句)
3. I can see a bird in the tree.(改为一般疑问句)
【考点三】“g” 和 “o” 发音规则
核心含义:掌握以 “g”“o” 开头或含 “g”“o” 字母的单词发音,提升听说能力。
1. 发音解析
1) “g” 发音:/g/,舌根后缩抵住软腭,然后快速张开,让气流冲出,声带振动。
例词:girl(女孩)、dog(狗)、got(得到)、bag(包)
2) “o” 发音:/ɒ/(英式)/ɑː/(美式),嘴唇收圆,稍突出,舌尖离开下齿,舌身后缩。
例词:orange(橙子)、dog(狗)、pod(豆荚)、on(在…… 上面)
2. 发音练习
1) 短语练习:green grass(绿色的草)、orange flower(橙色的花)、big bird(大鸟)、small dog(小狗)
2) 句子练习:The girl likes green grass.(这个女孩喜欢绿色的草。);There is an orange flower on the desk.(桌子上有一朵橙色的花。)
【大显身手】
一、判断下列单词中 “g” 或 “o” 的发音是否相同,相同打 “√”,不同打 “×”。

2. orange; on( )
3. got; bag( )
