看Manhattan Chapter 4(Parallelism),做最后的problem set时遇到1个问题(P62-T15),想请教一下大家:
Wrong:Dr. Crock's claims have been not corroborated by other scientists or published in a prestiglous journal but have nonetheless garnered a great deal of attention from the
public.
Right: Dr. Crock's claims have not been corroborated by other scientists or published in a prestiglous journal but have nonetheless garnered a great deal of attention from the
public.
究竟have been not与have not been有什么区别呢?正确的句子平衡关系是怎样的呢?
求教求教~~
