各位好，请教一下 在中央社英语新闻看到这则内容 http://focustaiwan.tw/news/asoc/201804030002.aspx Taiwanese teen threatening school in U.S. had handmade gun, ammo Thornton, Pennsylvania, April 2 (CNA) A Taiwanese student who was arrested in the United States last week for threatening to shoot up his school had built a 9mm handgun with parts bought online and had over 1,600 rounds of ammunition for various firearms, U.S. media reported Monday. An Tso Sun (孙安佐), 18, had approximately 225 rounds of 12-gauge ammo, 663 rounds of 9mm ammunition, 295 rounds of AR-15 ammunition, and 425 rounds of AK-47 ammo, cbsphilly.com said, citing Michael Chitwood, superintendent of the Upper Darby police in Pennsylvania. ------------ 想请教 1.一般新闻标题不都用现在式代替过去式吗？为何这则新闻的标题却用过去式 的had呢？ 2.第一段第三行and had over 1,600 rounds of ammunition...这个and had是过去式， 还是过去完成式（和前面的had built共用一个had）？不过第二段第一行确实是过去式的 had，因此第一段的and had似乎是过去式的可能较大？ 这两题贴於英语讨论区https://goo.gl/wb7FUU -------------- （更新）网友J&K Tutoring回应： 1. I doubt the student still has the weapon. 2. Simple past. Not the same as the additional example cited. 但我不懂第二题，为何前面用过去完成式，後面用过去式？为何不统一呢？ ------------- 3.（更新）usingenglish.com不顺的问题似乎目前已解决 4.因为上述新闻标题的疑惑找到了这个网站 http://htmfiles.englishhome.org/grammar/newsenglish_syntax.htm 但我对它末段的说明有疑惑： TOULOUSE, France, July 19 (AP) - A train moving at 30 miles an hour hit another train stopped with mechanical problems today and 15 people were reported wounded. 在上例中，"moving at 30 miles an hour" 和 "stopped with mechanical problems" 分别为现在分词 (moving) 与过去分词 (stopped) 片语。 其实，不管是同位语还是分词片语，它们都是关系子句，即形容词子句的减化。所以上例 可以改写或还原为 "A train which was moving at 30 miles an hour hit another train which had stopped with mechanical problems...."。 --------- stopped with mechanical problems如果原本是完成式的话， 应该减化成having stopped with mechanical problems....才对？ 原句似乎比较像是which was stopped/had been stopped with mechanical problems ....的减化？ 这则新闻的原始出处： https://www.nytimes.com/1988/07/20/world/15-hurt-in-french-crash.html 请教一下，谢谢！ --
