图中编号该编号所指结构的功能
控制物质进出细胞
使光能变成化学能
动力车间
遗传信息库

A.①

B.②

C.③

D.④

答案

由植物细胞模式图可知:①细胞壁、②细胞膜、③叶绿体、④细胞核、⑤液泡、⑥细胞质.①细胞壁是植物细胞最外层透明的薄壁,具有保护和支持细胞的作用;②细胞膜,紧贴细胞壁内侧,非常薄,在光学显微镜下不容易看清楚,起保护作用并控制物质进出的作用;③叶绿体是光合作用的场所,既是生产有机物的车间,也是将光能转变为化学能的能量转换器;④近似球形的细胞核是遗传信息库,控制着生物的发育和遗传.据上所述,只有选项D是正确的.

故选:D.

Question: Why is it so hard for some people to apologize after they’ve done something wrong? I have made every effort to persuade my uncle to be nice to people that he knows he’s hurt. 小题1:  How I wish things would be better if he’d just say he’s sorry and ask them to forgive him.

Answer: 小题2:  It’s just easier for him to pretend nothing happened than to face the embarrassment of admitting he was wrong. You’ve probably done the same thing yourself at some time. In fact, most of us have. Furthermore, what if others won’t forgive him even if he apologizes?

 小题3: Pride blinds us to our mistakes or faults. Or at least it makes us pay less attention to their seriousness.

Pride also makes us unwilling to admit to others that we were wrong. Perhaps we’re afraid they will look down on us if we admit it.  小题4:

But others see through our pride. And things would be far better if we admitted our faults and asked for forgiveness.  小题5:

Now you know why your uncle refuses to apologize, talk to him again. Help him to learn how to apologize and ask for forgiveness from others.

A.But a deeper reason is pride.

B.But he just refuses to do that.

C.We may even hope that somehow they will overlook it.

D.As a result, you would offend others and hurt their feelings.E. There are a variety of reasons for your uncle’s refusal to apologize.

F. Otherwise our pride would only hurt us and cause conflict with others.

G. One reason your uncle finds it hard to apologize could be embarrassment.
