我一开始写的是是sped at the downhill
原句it sped downhill at the end of the race
sped downhill中间不用介词。
因为downhill是副词,副词前面不需要介词;
就像我们见过的词组:go home(回家);get there(到那儿);come here(来这儿);go upstairs(上楼)。中间都没有介词。
词组意思: 快速下山;下山速降式;
解释单词:
1. downhill, /ˌdaʊnˈhɪl; ˈdaʊnhɪl/ ;
adv. 下坡;向下;每况愈下
adj. 下坡的;容易的
n. 下坡;滑降
例句:
He headed downhill toward the river.
他朝山脚下的小河走去。
The production in some areas went steadily downhill.
某些地区的生产在滑坡。
She bent at the knee when she skied downhill.
她滑雪下山时曲膝下蹲。
She took her feet off the pedals and coasted downhill.
她把脚从自行车的踏板上松开,沿山坡滑行而下。
2. sped,/sped/ ;
v. 加速;飞驰(speed 的过去分词);
例句:
He sped away on his bike.
他飞快地骑着车走了。
A car sped past, raising a cloud of dust.
汽车飞驰而过,卷起一阵尘土。
She sped away in her car .
她开车迅速离去。
