一、形容词在句中不但可以作定语、表语和补语,还可以作状语。形容词作状语时有以下一些特征: 1.形容词可单独作状语或引起短语作状语。例如: Ripethese apples are sweet. 熟了时这种苹果是很甜的。 Crusoe stared at the:footprint, f...一、形容词在句中不但可以作定语、表语和补语,还可以作状语。形容词作状语时有以下一些特征: 1.形容词可单独作状语或引起短语作状语。例如: Ripethese apples are sweet. 熟了时这种苹果是很甜的。 Crusoe stared at the:footprint, full of feat。克鲁索盯着脚印看,满心恐惧。展开更多
Let f∈C[-1, 1] and Tx（x）=cos（n are cosx） be the Chebyshev polynomial of degree n. Tn（x） has all its zeros in （-1, 1）, at the points xkn=cos （（2k-1）/2n）π（k=1,…, n）. We denote
