On varieties that are uniruled by lines
[摘要] Using the $sharp$-minimal model program of uniruled varieties we show that, for any pair $(X, {mathcal H})$ consisting of a reduced and irreducible variety $X$ of dimension $k geq 3$ and a globally generated big line bundle ${mathcal H}$ on $X$ with $d:= {mathcal H}^k$ and $n:= h^0(X, {mathcal H})-1$ such that $d
