"he climbed the steep slope"
"the house was built on the side of a mountain"
"a five-degree gradient"
"The terrain sloped down"
The manager sloped off with the contents of the cash register.
那经理卷款潜逃。
The outside the bank, sloped off when he saw a policeman approaching.
在银行门外转悠的那人一见到警察走近便匆匆走开了。
Don't think you can slope off just because my back's turned.
别以为我转过身去你就可以溜掉。
Let's slope off somewhere quiet and have a cigarette.
咱们溜到僻静处去抽支烟吧。
