America should reach Yemenis with education, with technology, positive one, not with weapons. But what’s happening, that they are receiving America like just weapons. この文の中で、 what is really sad, that S V は本来、 what is really sad is that S Vで、 また、what’s happening, that S V は 本来、what’s happening is that S V なのでしょうか？ 会話の中なので、こういうこともあるのでしょうか https://www.democracynow.org/2019/3/7/war_crimes_in_yemen_us_uk からの引用です。
