2. A few grammar tips
(1) Data: 复数（The data are...）
(2) Affect vs. effect (verb vs. noun，多数情况下)
(3) Compared to vs. compared with
Compared to = to point out similarities
Compared with = to point out differences between similar things
(4) That vs. which
"That" is the restrictive (defining) pronoun
后面的内容是必需的
"Which" is the nonrestrictive (non-defining) pronoun
后面的内容是可有可无的，extra information
That vs. which
(5) Singular antecedents
Do not use "they" or "their" when the subject is singular.
Singular antecedents
