1.1 如何指出当前研究的不⾜以及有⽬的地引导出⾃⼰的研究的重要性
通常在叙述了前⼈成果之后，⽤However来引导不⾜，⽐如
However, little information...
little attention has been devoted to…
little work...
little data / little research
or few studies / investigations / few attempts havebeen don on…
or none of these studies
has (have) been less
done on ... / focused on / attempted to
conducted / investigated / studied
(with respect to)
OR To the author's knowledge... There is little informationavailable in literature about...
Until recently, there is some lack of knowledge about...
Previous research (studies, records) has (have)
failed to consider
ignored
misinterpreted
neglected to
overestimated, underestimated
misleaded
thus, these previous results are
inconclusive / misleading…
unsatisfactory / questionable /controversial..
Uncertainties (discrepancies) still exist ...
⼀定要注意绝对不能全⾯否定前⼈的成果，即使在你看来前⼈的结论完全不对。这是前⼈⼯作最起码
的尊重，英⽂叫做给别⼈的⼯作credits.
所以⽂章不要出现⾮常negative的评价，⽐如Theirresults are wrong, very questionable, have no
commonsense, etc.
可以婉转地提出：
Their studies may be more reasonable if they had considered this situation.
Their results could be better convinced if they ...
Or Their conclusion may remain someuncertainties.
