Prices reach equilibrium at the level at which quantity demanded ______ quantity supplied.| A．is equal to | B．equal | C．equals to | D．is equal |
|
| A |
| 语法结构题。本句的难点是：be equal to意为“与…相等”，等于及物动词equal。任at which引导的定语从句中，主语为第三人称单数，而[B]项equal又没有词尾s，C.和D.两项的形式又不正确，所以[A]项正确，因其既合语法也合句意。本句的意思是：物价应在供求量相等的水平上达到平衡。 |
核心考点

Dear Mrs. Winthorp,
So my first week at college is over! No lectures this morning so I think I’d email you and let you know what things are going.
I’m glad to say that anything has worked out fine in the dorm. I remember asking for a room as far away from the lifts as possible and they find me a comfortable one on second floor. There are two girls from my course here and I plan to make friend with them so they we can help each other on the course work. Everyone else seems very nice and warmly here.
Well, I had better to stop now. I’m going to attend mine first lesson this afternoon, for I’ve got some preparation to make, Keep in touch.
Best,
Carol |
