1. anticipate He studies very hard every day so I anticipate that he will get great score. (we don't typically say 'score', but rather use 'marks' in this situation.) This is otherwise fine and makes sense. 2. unprecedented She can eat 20 bowls of rice at once, it is unprecedented. This is quite a novel context for this word, which usually precedes a noun (eg. an unprecedented achievement) but does make sense. The major error in this sentence is called a comma splice error (Which occurs when two sentences are joined by a comma). Rather use a colon, semi-colon or, even better, a full stop instead. (See above) Also remember to match your plurals- 1 bowl; 20 bowls. 3. discipline This company has strict discipline so no one dare late. The error in this sentence lies in "no one dare late", which needs the verb 'dare' to agree with the subject (no one). It is also better to say 'to be date' or 'be late' than "dare late". Discipline's context is good. 4. obstacle To success is not easy, you might meet a massive number of obstacles. Rather use 'succeed', as success is a noun. To make more sense, it is better to say: It is not easy to succeed/ success doesn't come easily. Try to also join the two phrases with a conjunction (e.g.. because/ as) to avoid the comma splice error. So: It is not easy to succeed, as you might meet a massive number of obstacles. With obstacles, you could also say 'to face obstacles' rather than 'to meet obstacles'. 5. excessive He was resign because he can't to handle the excessive work that was assign. The past participle 'was resign' is incorrect. Rather say 'he had resigned' or 'he resigned'. 'can't' needs to be in past tense to match the rest of the sentence, so 'he can't' becomes 'he couldn't.' Leave out the 'to' in 'to handle', as it is unnecessary. Finally, 'was assign' should be 'was assigned' (past tense) Hope this helps!
