The question about the verb tense in the sentence ‘Experts examined what those animals eat’ is a great opportunity to dive into English grammar, especially when it comes to reported speech and tense shifts. In this case, we are dealing with a situation where the main clause is in the past tense, but the verb in the subordinate clause remains in the present tense.
1. Understanding Tense Shifts in Reported Speech
In English, when you report something that someone has said, you typically shift the tense of the original sentence. However, this shift is not always necessary, especially when the reported statement is a general truth or a fact that still holds. This is why, in the sentence ‘Experts examined what those animals eat,’ the verb ‘eat’ remains in the present tense, even though the main clause ‘examined’ is in the past tense.
2. General Truths and Facts in Reported Speech
The phrase ‘what those animals eat’ refers to a general truth — animals continue to eat the same things regardless of when the experts examined them. Therefore, the present tense ‘eat’ is used because it is still valid and true at the time of reporting. In other words, the action described (the animals’ eating habits) is ongoing and not tied to the specific moment of the examination.
3. Why ‘Ate’ is Not Used in This Context
If the sentence were referring to a specific event in the past (e.g., a particular day or moment when the experts observed what the animals ate), then the verb would likely change to ‘ate’ to reflect the past action. However, because the focus is on a general truth, ‘eat’ is used to show that the behavior is constant or timeless, which is why the verb stays in the present tense even with a past tense reporting verb.
4. Other Examples of General Truths in Reported Speech
Here are a few more examples where the verb in the subordinate clause remains in the present tense, even though the main clause is in the past tense:
- She explained how the Earth orbits the Sun.
- He described what time the train departs every day.
In each case, the subordinate clause expresses a fact or general truth that does not change with time, which is why the present tense is used even in the context of past-tense reporting.
5. Summary
In reported speech, the choice of verb tense in the subordinate clause depends on whether the information is a timeless fact or a specific event. In the sentence ‘Experts examined what those animals eat,’ the use of the present tense ‘eat’ is correct because it refers to a general truth, not a specific past event. Understanding this nuance helps ensure proper tense usage in English grammar.
