(some + countable noun) People can get some information about dinosaurs from their fossils. (some + uncountable noun) I don’t have any questions about dinosaurs. (any + uncountable noun) Can people get any information about dinosaurs from their fossils (any + countable noun) We use some and any to talk about amounts. 学习理解 02 A some and any Su Wen is interviewing Dr Xing, a dinosaur expert, for his project. Read the interview and pay attention to the words in bold. We use some and any as determiners to talk about amounts. We also use them as indefinite pronouns to refer to people or things. Su Wen: Dr Xing: Hi, Dr Xing, can I ask you some questions about dinosaurs Of course! Su Wen: Why did dinosaurs die out Dr Xing: Many scientists think that dinosaurs died out because a huge asteroid (小行星）hit the Earth. However, some scientists don't accept this theory. Su Wen: What do scientists disagree about Dr Xing: Some scientists think the world became too cold for dinosaurs. Some believe there was not enough food for dinosaurs. Su Wen: Do you have any theories yourself Dr Xing：I have my own theory, but there isn‘t any sound proof for it yet. We still need to find more fossils... We use some and any before plural countable nouns and uncountable nouns. We usually use some in positive statements, and any in negative statements and questions. We use some in questions when we expect the answer to be ’yes”. It is also a polite way to ask. Would you like some tea May I have dome noodles We can use any to talk about someone or something when we do not refer to a specific person or thing. Wu can take any book you’d like to read.
