原文：
Autism affects people's social behaviour and communication,
and may impair their ability to learn things. All this is well known.
Less familiar to most, though, are the gastrointestinal problems
associated with the condition. (*1)
The intestines of children with autism often harbour bacteria
different from those in the guts of the neurotypical. As a consequence,
such people are more than three times as likely as others (*2)
are to develop serious alimentary canal disorders at some point in their lives.
Unfortunate though this is, (*3)
the upset gut floras of autistic people are seen by some investigators
as the key to the condition and to treating it.
问题：
(*1) 倒装句？ 使用倒装的手法是为了强调 less familiar to most ?
(*2) 此句倍数比较级的句构分析是对的吗？
A be-V ( more than ) 倍数词 ＋ as + 原级 adj + as + B
＝ A be-V ( more than ) 倍数词 ＋ 比较级 adj + than + B
-> such people are more than three times more likely than others
这样改写是对的吗？
还是有用到 more than + 倍数词，应该要搭配 as….as 句构比较好？
(*3) 也是倒装句？ 为啥这句可以倒装？( 是因为要强调否定字在句首才倒装？)
为什么不直接写个 unfortunately 就好？
谢谢 ：）

非倒装的写法-> Yes. 参考 https://tinyurl.com/y8lh4kde1. Yes. Yes.2. "more than"只是为了表达是多于三倍(只是修饰three times)。要方便理解的话，比如我挑个5倍好了(5倍符合"morethan three times)->"..., such people are five times as likely asothers are to ..."不要改写，毕竟你读文章的目的就是学习你之前不会的习惯表达方式。你越改写，你脑子里头接触/熟悉这新的表达法的时间就越短。如果你是不熟悉 "... as likely as ..."，那么就找这方面的文法书/网站来看。3. Yes. 本来就有这用法，学起来就是。因为作者喜欢这个惯用法。另外就是单独一个"unfortunately"意思较广/模糊，不如原惯用表达的意思集中

我知道most是代名词,也看得懂意思...只是觉得原句是否应该是：The gastrointestinal problemsassociated with the condition are less familiarto most. ( 非倒装的原句 )

1. less familiar to most 应该理解为，人们较不熟悉的是...，most这里做代名词

2. are as likely as are？
