Dear Xenia, thank you for submitting your answers to these questions. You have written good sentences with mostly correct Chinese.

Some tips for you to get more fluent language:

1. 人类与其他动物是什么关系？

- 人类和其他动物是老故人老朋友。把动物我们把动物都研究，驯化，养在家里。宠物爱我们，野生动物害怕我们。

-“老朋友 (old friends)" is an usual expression, and the word "故人 (old acquaintances)" is used occasionally in written language, in which "故" means "old". Therefore it is incorrect to say "老故人".

-In a sentence, the object with preposition "把" should be immediately behind the subject and in front of the verb.

-In modern Chinese, we state the whole sentence with all its constituents. Don't omit the subject/verb/object.

2。 把鸟养在家里是对它们的爱吗？为什么？

- 把野鸟养在家里不是对它的爱，而是自私的。但是我觉得正确照料住在人家里住被正确照料的宠鸟宠物鸟都很幸福。

-Just remember the phrase"不是……而是……(not...but...)" and use it when you highlight the contrast between two subjects.

-The verb "住 (to live)"should be placed in front of the adverb/adverbial. There before the verb "照料“ should be a "被" to form a passive phrase because the birds are being taken care of.

-When an adjective plays the role of the predictate, consider to add an adverb "很" before it. This "很 (very)" is anctually meaningless but equilibrates the sentence subtly，especially when the adjective doesn't end with "的".

3。 人和动物的比赛是平等的吗？

- 我觉得人类和其他动物的比赛是左右平等不公平的。虽然我们有工具和枪，野生动物也非常有害的可能伤人。

-I guess that you mean the competition manipulates (左右) justice. However "左右公平" sounds kind of wierd because there is nobody manipulating the competition. You can simply say "不公平 (unfair/unjust)" instead.

-Do you mean that wild animals may hurt people? The word "有害的" can mean "(being) harmful/detrimental/toxic", but is not apropriate here, because it is always abstract about the harmfulness of the subject. "可能伤人 (may hurt people)" is more recommended in the context.

Thank you again for reading these suggestions. May they be of some help to you. And it would be benefitial to read plenty of example sentences in the dictionaries, for the more you read them, the more you get familiar with common Chinese expressions.

回答教学的问题

1。 人类与其他动物是什么关系？

- 人类和其他动物是老故人。把动物我们都研究，驯化，养在家里。宠物爱我们，野生害怕。

*人类和其他动物是老朋友。(故人：本身有老朋友的意思，不需要加“老”。故人，一般用于古代文学，所以“朋友”更合适)。

我们研究动物(主谓宾的顺序更通顺)，在家驯养动物。(“驯化”和“养”可以用“驯养”一个词)

宠物喜欢我们，野生动物害怕我们／野生动物怕人。(宠物用“喜欢”比“爱”合适，动物和人之间一般用“喜欢”)(“野生”后面加上“动物”，害怕后面加上宾语“我们”)

2。 把鸟养在家里是对它们的爱吗？为什么？

- 把野鸟养在家里不是对它的爱，是自私的。但是我觉得正确照料在人家里住的宠鸟都幸福。

*但是我觉得，家里的宠物鸟，如果受到正确／精心照料，都是幸福的。(“家里的”，没有语境[context]说明是自己家里的话，可以指人们家里)(照料，或许可以用“精心照料”)(加上“如果”，可以变成几个短句，更符合中文语法)

3。 人和动物的比赛是平等的吗？

- 我觉得人类和其他动物的比赛是左右平等的。

＊我觉得人类和其他动物的竞争是左右平等的。(比赛，改用“竞争”[compete]更合适)

虽然我们有工具和枪野生动物也非常有害的。

*虽然我们有枪等工具，野生动物也非常有害。(枪也是工具的一种)(中间加个逗号，更合适)
