Although the first pulsar, or rapidly spinning collapsed star, to be sighted was in the summer of 1967 by graduate student Jocelyn Bell, it had not been announced until February, 1968.
(A) Although the first pulsar, or rapidly spinning collapsed star, to be sighted was in the summer of 1967 by graduate student Jocelyn Bell, it had not been announced until February, 1968.
(B) Although not announced until February, 1968, in the summer of 1967 graduate student Jocelyn Bell observed the first pulsar, or rapidly spinning collapsed star, to be sighted.
(C) Although observed by graduate student Jocelyn Bell in the summer of 1967, the discovery of the first sighted pulsar, or rapidly spinning collapsed star, had not been announced before February, 1968.
(D) The first pulsar, or rapidly spinning collapsed star, to be sighted was observed in the summer of 1967 by graduate student Jocelyn Bell, but the discovery was not announced until February, 1968.
(E) The first sighted pulsar, or rapidly spinning collapsed star, was not announced until February, 1968, while it was observed in the summer of 1967 by graduate student Jocelyn Bell.
答案是d。
感觉这题只能用排除法。
但是d选项我有一点想不通,to be sighted 在这里是什么意思。 按照sight的意思来说,它根observe是重复的。
我用这里理由,排除了d的
是的。
不过我的一个缺点就是,用一个理由排除掉几个选项后,就不会再看它们,然后对剩
下的2个选项就采用非常宽松的标准。尤其是长句子,是我的超级弱项。唉
是的。

同感啊。我告诉自己要吸取教训,不过还是难免有时候忘记

我做完这题都没发现你说的。为自己的粗枝大叶汗一个。不过要是真发现了我肯定得耗半天,想不通。末了说不定也得选错。
我猜想to be sighted的意思是根据某个科学假设去被观测。然后果然被observe到了。
pulsar:脉冲星
还真不明白什么意思,于是搜了下,注意看最后2段,假设是早就有了,只是没有观测到。
脉冲星
alice解答得很详细啊~~
