6 . 虚拟语气用在would rather后的从句中would rather意思是“宁愿、希望〞,是英语中常见的一个惯用句式, 如果它的后面接句子,那么从句习惯上要用虚拟语气。
本节课教师就和同学们一起来学习一下这种虚拟语气。
一.would rather后虚拟语气的规如此1. 从句使用一般过去时表达现在或将来的愿望——would rather sb. did sth.I would rather you posted the letter right away. 〔现在的愿望〕我宁愿你马上把这封信寄出去。
Don’t come tomorrow. I’d rather you came next weekend.(将来的愿望)明天就别来了,我希望你下周末过来。
2.从句使用过去完成时表达过去的愿望——would rather sb. had done sth.She would rather that you had not arrived last night.她宁愿你昨天晚上没有来。
He would rather mum had not told him the truth.他宁愿妈妈不告诉他真相。
二.典型例题1. I’d rather you________make any comment on the issue for the time being.A. don’tB. wouldn’tC. didn’tD.shouldn’t解题思路:①牢记would rather后的从句应该使用虚拟语气这一考查点;②根据时间状语判断虚拟语气的时间;③根据所表达的虚拟时间选择适宜的时态。
解析:would rather后的从句需要使用虚拟语气,题干中的时间状语for the time being意为“目前,现在〞,所以此题表达的是现在的愿望,从句中应该使用一般过去时。
2.To be frank, I would rather you ________the teacher’s advice last week.A. followedB. had followedC. would followD. have followed解题思路:①牢记would rather后的从句应该使用虚拟语气这一考查点;②根据时间状语判断虚拟语气的时间;③根据所表达的虚拟时间选择适宜的时态。

In this comment we explain the discrepancy found between the results in arXiv:0712.1716v1for the 3PN spin-spin potential and those previously derived in gr-qc/0604099.We point out that to compare one must include sub-leading lower order spin-orbit effects which contribute to the spin-spin potential once one transforms to the PN frame.When these effects are included the results in arXiv:0712.1716v1do indeed reproduce those found in gr-qc/0604099.In [1]we applied recently developed Effective Field Theory (EFT)techniques [2,4]to compute the next to leading order (NLO)potential due to spin(1)-spin(2)interactions in the Newton-Wigner (NW)spin supplementarity condition (SSC).In [5]the NLO spin(1)-spin(2)was also calculated.Given our claim that,up to 4PN order the equations of motion in the spin(1)-spin(2)sector can be obtained via the traditional Hamiltonian approach [1,6],the authors then searched for the canonical transformation necessary to go between the results,finding that no such transformation exists.However,in order to compare one must also consider spin-orbit effects,including a subleading one which becomes a spin(1)spin(2)-orbit term once written in terms of the coordinate velocity in the post-Newtonian one.In fact,once this new term is added,the result in [5]do indeed reproduce the potential calculated in [1].The spin-orbit 1.5PN potential is given by [4,6]V so 1.5P N =G N m 22ωab µS ab with ωab µthe Ricci rotation coefficients.Expanding around flat space we have e b µ=δb µ+h νµdt ,then reads S i 01=12S ij 1e j 0( x 1)+...=12r 2 ( n × S 2)× S 1 i +...,(2)where we have e j 0=H j 0/2=
G N 2h 0i,j S
ij [1,4],or by simple inspection of the Kerr metric in harmonic gauge.A similar term follows for particle 2.
In the EFT approach [1,2,4,6]each vertex scales with different power of spin,and velocity,and therefore spin(1)-spin(2)interactions are those for which there is a spin tensor on each vertex.On the other hand spin-orbit terms are those for which the spin of one of the bodies interacts with the motion of the companion.As we can see from (1)and
(2),to obtain the full S 1S 2Hamiltonian up to 3PN we need to include a spin(1)spin(2)-orbit term given by
