第七单元
第一章 生物的生殖和发育
第一节 植物的生殖
1．有性生殖：由两性生殖细胞结合成受精卵发育成新个体的生殖方式。例如：种子繁殖（通过开花、传粉并结出果实，由果实中的种子来繁殖后代。）（胚珠中的卵细胞与花粉中的精子结合成受精卵→胚→种子）
有性生殖的过程：开花→传粉→受精→结实→新一代植株。
2．无性生殖：不经过两性生殖细胞的结合，由母体直接产生新个体。
应用：扦插，嫁接，压条，分株、组织培养等。
（1）甘薯、葡萄、菊、月季的栽培，常用扦插的方法。
（2）苹果、梨、桃等很多果树都是利用嫁接来繁育优良品种的。
嫁接就是把一个植物体的芽或枝（接穗），接在另一个植物体（砧木）上，使结合在一起的两部分长成一个完整的植物体。嫁接有枝接和芽接两种。
嫁接的关键:接穗与砧木的形成层紧密结合,以确保成活。
（3）植物的无性生殖需要的条件：以扦插为例，除去光照、水分、温度、湿度等环境条件外，用作扦插的植物茎段还需要具备以下条件（例如紫背天葵）：
a.茎剪成15－20厘米长的茎段，一般每段保留两个节。
b.茎段上方的切口是水平（减小伤口水分过多蒸发）的，而茎段下方的切口则是斜向（可以增加吸收水分的面积）的。
c.上一个节上的叶要去掉部分叶片，下面一个节上的叶从叶柄处全部去掉。（一般说在节的部位居间分生组织发达，此处较易生根。去掉叶片时，叶柄在节上留下伤痕，伤口处较容易产生愈伤组织，也就容易生根。）
（4）将马铃薯的块茎切成小块来种植时，每一小块都要带一个芽眼。
第二节 昆虫的生殖和发育
1.变态发育：在由受精卵发育成新个体的过程中，家蚕的幼虫与成体的形态结构和生活习性差异很大，这种发育过程称为变态发育。
（1）完全变态： 同家蚕一样，蜜蜂、菜粉蝶、蝇、蚊、蛾等昆虫的发育也要经过卵、幼虫、蛹、成虫四个时期，这样的发育过程称为完全变态。
（2）不完全变态：蝗虫的发育过程要经过卵、若虫、成虫三个时期，像这样的发育过程，称为不完全变态。不完全变态的昆虫还有蝉、蟋蟀、蝼蛄、螳螂。

Can you give me a little ink? 我的瓶子里没有墨水了，你能给我点儿墨水吗？5. not…until 直到…(否定句) 才......，动词为短暂性或瞬间性动词。She didn’t leave until we came.He went shopping after he got up. =He didn’t go shopping until /before he got up. ...until/till 直到......（肯定句）动词为延续性动词We stayed here till/until 12 o’clock.Unit2 I'll help clean the city parks.
