I have two questions. Thank you very much。

Hi,friend. I understand the word(or phrase):"tie-ups", but what is the two words meanings respectively? and why put the two words together means "collaboration"? Thank you very much.

How canwe understand the words“as might”? Is it a phrase? If not, how can we understand them respectively? Thank you very much.

In this sentence, how can we understand the"one"and the "as"? I think the "one" means vegetable or vegetarian? Which is better? And I think the "as" means "because", am I right? Thank you.

How can we understand this sentence? I was lucky to have her again for the first grade, and learned to love school and learning. She was right about living my life without long-lasting attention from my mommy. How can we understand the last sentence? Does it means "that she is here is good for my growing up"? How can we understand the "right" here? I don't think it means "correct", what's your opinion?

How can we understand “how” here? Thank you. How should you start? Modestly, so as not to become discouraged. I think of one friend who couldn’t arrange flowers to satisfy herself. She was curious about how the experts did it. How she is one of the experts, writing books on flower arrangement. In the last sentence:"How she is one of the experts...", how can we understand the "how". Does the sentence means:" How does she become a experts..."?

The sentence feels weird, it there lack of "——”? Thank you. After years of observing human nature, I have decided that two qualities make the difference between men of great achievement and men of average performance curiosity and discontent. I think this sentence is weird when read,specially the last three words. How can adjust it, putting a dash before "curiosity" is ok?

What's the meaning of the sentence in this paragraph? please. The beauty of rereading lies in the idea that our bond with the work is based on our present mental register. It's true, the older I get, the more I feel time has wings. But with reading, it's all about the present. It's about the now and what one contributes to be now, because reading is a give and take between author and reader. Each has to pull their own weight. How can we understand "what one contributes to be now" exactly? Thank you for your answer.

What's the meaning of the word in this sentence? This year marks exactly two countries since the publication of Frankenstein; or, The Modern Prometheus, by Mary Shelley. Even before the invention of the electric light bulb, the author produced a remarkable work of speculative fiction that would foreshadow many ethical questions to be raised by technologies yet to come. This year marks exactly two countries...... two countries? I don't understand. The followings are two books, aren't they? Why countires?
