自行车— Part 1 評分報告

建議: 回答的主要问题是词汇和时态错误：你说的是自行车，但使用了“bag”，应改为“bike”；过去的经历要统一使用一般过去时，如“had”“bought”“taught”。另外，“when I was about 18”不太符合“when you were a child”，可以改成具体的童年年龄。建议先直接回答，再补充自行车的颜色、购买者以及你使用它的情况，并使用“because”或“so”连接细节。

範例: Yes, I did. I had a green bike when I was about eight years old, and my dad bought it for me. He taught me how to ride it, so I often cycled around my neighborhood after school.

建議: 回答中存在多处表达问题：“taking bike”应改为“riding a bike”，“unpopular”与题意相反，应使用“popular”，而“work”不能表达骑自行车这项活动。不要说“nowadays I am 20 years old”，因为年龄与问题无关。建议先明确回答“Bikes are very popular”，然后说明原因，例如环保、方便、缓解交通，并加入具体场景或例子；注意使用现在时，如“are”“people ride”。

範例: Yes, bikes are very popular in China, especially in large cities. Many people ride shared bikes because they are convenient and environmentally friendly. They are also useful for short trips when the roads are crowded.

× Yes I did. I have a green bag when I was about 18 which my daddy bought for me and he told me how to ride it, how to use it.

✓ Yes, I did. I had a green bike when I was about 18, which my daddy bought for me. He taught me how to ride it and how to use it.

句子描述的是童年时期的经历，所以动词应该使用一般过去时。原句中的“I have”表示现在拥有，和“when I was about 18”这一过去时间不一致，应改为“I had”。另外，根据问题语境，应该是“bike”而不是“bag”。建议看到“when I was...”等过去时间标志时，检查主句动词是否也使用过去时。

× Yes, nowadays I am 20 years old and also like taking bike and it almost become unpopular work in China.

✓ Yes, nowadays I am 20 years old and also like riding a bike, and it almost becomes an unpopular activity in China.

可数名词“bike”前通常需要冠词，应该说“a bike”，不能说“taking bike”。“activity”是可数名词单数，前面也需要冠词“an”，所以应说“an unpopular activity”。建议使用单数可数名词时，检查前面是否需要“a/an/the”。

× Yes, nowadays I am 20 years old and also like taking bike and it almost become unpopular work in China.

✓ Yes, nowadays I am 20 years old and also like riding a bike, and it has almost become an unpopular activity in China.

原句中的“become”形式不正确。这里表达的是从过去到现在已经发生的变化，应该使用现在完成时“has become”。主语“it”是第三人称单数，因此要使用“has”。建议表达“已经发生的变化”时使用“has/have + 过去分词”。

× Yes, nowadays I am 20 years old and also like taking bike and it almost become unpopular work in China.

✓ Yes, nowadays I am 20 years old and also like riding a bike, and it has almost become an unpopular activity in China.

主语“it”是第三人称单数，因此后面的助动词必须使用“has”，不能使用“have”。正确结构是“it has become”。建议先找出句子的主语，再根据主语是单数还是复数选择正确的动词形式。
