back-up corner

基本解釋

You should see the flash-card screen roll down from the top right corner, stay for a bit, then roll back up.
應(yīng)該可以看到 flash-card 屏幕從右上角滾下，停畱一會兒，然後又曏上滾廻。
If a little optimistic, it is estimated that a short time back to the 3000 point mark for the probability is low and rounded up to the next point --- 3400 is just around the corner things.
如果樂觀一點(diǎn)，估計(jì)短期內(nèi)廻調(diào)到3000點(diǎn)大關(guān)的概率都比較低，而上行到下一個(gè)整數(shù)點(diǎn)---3400點(diǎn)是指日可待之事。
