表示举例时用such as，而不是用like。

this is the problem. if "with ____" is modifying xxxxx, then it should be describing some aspect, or sub-component, of xxxxx.

here, "each" = each style of cooking.
we can't use "with each style of cooking..." to describe "styles of cooking".

等比数列求和公式s={a1(1-q^n)}/(1-q)
原式=2+s

条件2竟然是说q的股票价值。。。。太坑了

主要搞清楚z=x+y

300x+1500y=9100,y

我把y取的1....

题目没读懂，我以为是标准差，比平均值少2.
话说“2个标准”差就直接用2 standard deviation吗？好歹有个2times啊～～这个倍数表达也太偷懒了吧～～～

做着做着把G当成了保护层。。。。。大哭。

第二个条件用数字试

AC纠结；A读的懂 C读不懂；C中的unwilling是修饰啥的？句意好模糊啊

个人理解是要把上述两件事串联起来

screen 检查

B:This choice correctly conveys the logical intended meaning. The comma + verb-ing modifier displacing has been turned to simple present tense verb displaces. The comma + verb-ing modifier rendering correctly modifies the preceding action displaces, presenting the result of this action. Because the leafy spurge displaces grasses and other cattle food, it renders rangeland worthless.

世道变了，that前面有逗号都可以不是非限制性定语从句了- -

从意思的角度老说B也不连贯， 这里的 it是个形式主语，导致后半句与前半句的关系说不清

虽然选对了，还想知道A要怎么改

AE： fossils made 逻辑意思错误

A选项中的“it”是不是也不对啊？它可以指代前面的sloth吗？

disagreement regarding不是use，而是IT技术本身
