问题:

“基善”计划是一大创举,因为它的目标是制造一片云,但其实很早以前人类就已经在无意中制造出了人造云。这是因为在大海里航行的大轮船和在空中飞行的飞机,它们的烟囱和引擎在大气层里洒下微粒,成为水滴的凝结核,这些微粒使水汽在它周围凝结成云。这就是我们在天空中看到的像白带子一样的云。这一现象对科学家来说意义重大。这些人造云覆盖了地球0.1%以上的面积,并且已经被证明能够对气候产生影响。这是因为天空中的人造云具有隔离效果,它们反射阳光,使部分太阳热量无法到达地面。 对文中划线句理解不正确的是( )

A.大轮船和飞机制造出来的人造云已经被证实能够对气候产生影响

B.“基善”计划制造出的人造云可以产生降水,从而改变沙漠地区的干旱状况

C.如果没有大轮船和飞机制造出来的人造云,全球气温很有可能会上升

D.像白带子一样的云具有隔离效果,它们反射阳光,使部分太阳热量无法到达地面

     It's Saturday afternoon. Tanya is going to the laundromat(自助洗衣店)on Lincoln Street. She

needs to wash her clothes.

     There are many people inside the laundromat. Everyone is washing clothes. Tanya has two loads

of laundry. One load is for colours, and the other is for whites, but Tanya sees only one empty washing

machine.

Tanya thinks, "I don't want to wait for another machine. My loads are small. I will put them together

in one machine."

     The washing machine stops after thirty minutes. Tanya opens it and takes out her clothes. Oh, no!
