這四句英文在文法上有什麼錯? 括住個部份, 請提供詳盡解釋和正確寫法

We need an anti-racism law because some people in Hong Kong {discrimate AGAINST south Asian people.}
discriminate係不同待遇咁解，所以唔同中文「歧視」，可以好可以差。「有優待」的話係 discriminate in favour of ，「歧視」係 discriminate against
A full week of torrential rain {resulted IN a flood that killed} hundreds of people.
「引致」係 result in
I {suggest you visit} Temple Street Night Market if you are looking for cheep goods.
複雜囉。suggest應用 present tense 之餘，呢句其實係一個叫 subjunctive o既 grammar structure，相當 formal，常用o既 verbs 如 ask，recommend，insist，suggest，用時連第三身單數都唔加 s，如：
I insist that he come here at once.
The raging typhoon {prevented many airplanes FROM landING} at Chek Lap Kok.
prevent 後必須要用 from 帶出避免o既事情，既然係事情，即係名詞，呢度就要用 gerund

3. I SUGGEST you to visit Temple Street Night Market if you are looking for CHEAP goods.

- The above is also wrong; take out TO in front of visit.


4. The raging typhoon prevented many airplanes to land at Chek Lap Kok.

- airplanes FROM LANDING at

ALL MISTAKES ARE IN BLOCK LETTERS

1. We need an anti-racism law because some people in Hong Kong discriminate AGAINST South Asian people.

discriminate AGAINST some people NOT discriminate people

2. A full week of torrential rain resulted IN a flood that killed hundreds of people.
result IN something NOT result something

3. I SUGGEST you to visit Temple Street Night Market if you are looking for CHEAP goods.

this is a PRESENT TENSE SENTENCE so use SUGGEST not SUGGESTED; also CHEAP is correct spelling not cheep

4. The raging typhoon prevented many airplanes to land at Chek Lap Kok.

the whole sentence is grammatically correct
