大学英语常见错误3-1-2

【误】I need the second car.

【正】I need a second car.

我还需要另外一辆车。

a second表示“再一的，另一的”。如：

Your shes may get wet. Bring a second pair.

你的鞋可能会湿，带上一双备用。

【误】He went up the stairs two at one time.

【正】He went up the stairs two at a time.

他两步并一步上了楼梯。

at a time是“每次，一次”。at one time = in the past是“曾经，一度”的意思。如：

At one time, Nigeria was a British colony.

过去尼日利亚曾是英国殖民地。

【误】As a matter of the fact, he was the one who broke the window.

【正】As a matter of fact, he was the one who broke the window.

事实上，他就是打破窗子的人。

as a matter of fact = in fact是个固定词组

【误】You needn't be in such hurry.

【正】You needn't be in such a hurry.

你不必如此匆忙。

in a hurry是固定词组，表示“匆忙，立即”。

【误】His brother had the high fever.

【正】His brother had a high fever.

他弟弟昨天发高烧。

表示“生病”时，以have构成的词组要用a，have a cold/cough/fever/pain/headache，另外还有have a good time，have a talk with sb.，have a meeting/match

以catch或take构成的词组，如：

catch a cold，take a cold，可省去a

如果名词前有形容词时，则都不可省。

“患流行性感冒”用a或the均可。如：

have a flu

have the flu
