1. 由此可见，因此可以得出【因果】
(Given/Judging/From/If..., ) It follows that...
It follows, (given/if/judging...), that...
Mr Mattis has argued that, judging both by its declared philosophy and its growing arsenal, Russia could in certain situations resort to “battlefield” nuclear weapons in the belief that America would not want to respond to the use of a low-yield nuclear weapon by annihilating Moscow. It follows that America needs to be able to match Russia at every level of escalation.
考虑到俄罗斯的战争理念以及其不断增长的武器库，它有可能在某些情况下对美国动用核武器，因为它认为美国不会因为俄罗斯使用低当量核武器就将莫斯科夷为平地。因此，美国需要在和俄罗斯的冲突中保持旗鼓相当。
2. a force for good 【优点】
X is a force for good by doing...
But when many in the West are contemplating their future with new foreboding, it is important to understand why the sceptics are wrong; why economic integration is a force for good; and why globalisation, far from being the greatest cause of poverty, is its only feasible cure.
3. X have/has a (good/convincing/strong...) case for/against ...to make X有充分理由......【理由】
There is a good case for/against...
make the economical/cultural/political/... case for... 在经济/文化/政治方面有充分理由
Typically, countries connect citizens with vast grid-extension programmes. Big grids make perfect sense for populous places. They can cheaply supply power generated far away to millions and, as they incorporate more wind and solar energy, they are becoming greener. But in remote places, the economic case for grids becomes hard to make.
这里case是熟词生义，它的含义是“论点；事实”(a set of facts and arguments that you can state for or against something);
the economic case for grids becomes hard to make 字面意思即“电网在经济上的理由并不充分”，引申为“使用电网在经济上并不划算”。（这跟前面提到过的make financial sense有异曲同工之处）
造句：
The economic case for free trade is compelling. 自由贸易的经济理由令人信服/自由贸易具有很令人信服的经济意义。
Countries seeking a modest relaxation have a strong case to make. 寻求适度放松的国家有充分的理由。
