英語(yǔ)四級(jí)閱讀關(guān)鍵句：284. The Centers for Disease Control

284. The Centers for Disease Control, for example, found that less than one-fourth of overweight adults who were trying to shed pounds said they were combining exercise with their diet.

譯文

比如說，疾病控制中心發(fā)現(xiàn)，只有不到四分之一的想要減肥的超重成年人說他們把運(yùn)動(dòng)與節(jié)食結(jié)合了起來。

點(diǎn)睛

本句的主干是The Centers for Disease Control found that。for example為插入語(yǔ)；that引導(dǎo)的是found的賓語(yǔ)從句，其中who were trying to shed pounds是overweight adults的定語(yǔ)從句；they were combining exercise with their diet為said的賓語(yǔ)從句。

shed pounds的意思是“減輕體重”，相當(dāng)于shed stones。如：

I'd like to shed a few pounds. 我想減掉幾磅體重。

combine...with...的意思是“將……與……結(jié)合起來，混合”。如：

Remember to combine the eggs with a little flour. 記得把雞蛋和少量面粉混合在一起。
