将一首英文诗分两行写入文本文件：（第一行）If you shed tears when you miss the sun, you also miss the stars.（第二行）let life be beautiful like summer flowers and death like autumn leaves. 然后，将文件中所有的单词like替换为seem like。

好的，我明白了。这是一个文件操作和文本替换的问题。以下是我的解决方案：

首先，将这首诗的两行分别写入一个文本文件，例如 poetry.txt，每行末尾需要加上换行符：

If you shed tears when you miss the sun, you also miss the stars.
let life be beautiful like summer flowers and death like autumn leaves.

然后，我们可以使用 Python 的文件操作和字符串替换功能，读取文件内容，将所有的 "like" 替换为 "seem like"，并将修改后的内容重新写入文件：

# 读取文件内容
with open("poetry.txt", "r") as f:
    content = f.read()

# 替换字符串
content = content.replace("like", "seem like")

# 重新写入文件
with open("poetry.txt", "w") as f:
    f.write(content)

执行以上代码后，poetry.txt 文件中的内容将变为：

If you shed tears when you miss the sun, you also miss the stars.
let life be beautiful seem like summer flowers and death seem like autumn leaves.

希望这个解决方案能够帮到你！
