Count me in =v=b

But it's the same prob as the Chinese one above, Japanese is not my native :(. But we can help each other right? =v=

Do these sentences sound natural?

He didn't want to eat breakfast, so didn't I either. => that would be "I didn't either"
He didn't want to eat breakfast, neither did I. => I would split the 2 clauses into 2 individual sentences, but that's ok

Forty people were on the waiting list on the wide TV screen above the registration desk for people that will enroll as new patients. => it's like a mess and can hardly understand what you were trying to say @@. But I think it is: on the wide TV screen above the registration desk, (there are 40 people being/ 40 people are) on the waiting list to enroll as new patients

you should split the adverbial phrase, subject and verb as clearly as possible so that people can not misunderstand it :D

Abstract 

For now, the process of economic globalization has accelerated very rapidly. Economic cooperation and technological exchanges are deepening worldwide. Economic globalization has brought fierce competition and made extensive impact to the world. Multinational enterprises (MNEs) with strong competitiveness play an important role in the process of economic globalization. There are several international operations types (I can barely find this word on the internet, do you mean "foreign operation modes"?) of multinational enterprises, such as: production, investment marketing, and R&D. The R&D internationalization is (the) highest type of economic globalization. It is the result of further deepening of MNEs development.
The R&D internationalization of MNEs provides developing countries which have higher (high is enough, don't need "er") skills and technology base (with) an opportunity to enhance their creative capabilities.
It can bring China many benefits from different aspects. For instance: knowledge spillovers, industrial competitiveness and optimized allocation of human resource.
The purpose of this paper (do you mean "essay" or sth like that :-?) is to found (replace with "find") out the positive impacts of MNEs China-based R&D institutions. Give (the subject is missing, you can combine it with the previous sentence by replacing the dot with the comma "," and changing "give" to "giving") proper policy suggestions through (i would prefer "using") empirical and theoretical analysis.
The paper is arranged in (divided into) five parts. Part 1 discussed (discusses) the background and (the) significance of the subject. Part 2 introduced (introduces) major theories of MNEs, included Monopolistic advantage theory, OLI theory. Part 3 & 4 are impacts and suggestions.

Quite a good piece of paper :D. But when you got more to the end, it seems like you were likely to make simple mistakes like past/ present tense

Keep up the good work :D
