2013年8月15日，甲公司向乙公司发出传真订货，该传真列明了所需货物的种类、数量、质量、供货时间、交货方式等，并要求乙公司在10日内报价。乙公司接受甲公司发出传真列明的条件，并于8月20日按期报价，在其发出的传真中亦要求甲公司在10日内回复；甲公司同样按期复电同意其价格，并要求签订书面合同。

乙公司在未与甲公司签订书面合同的情况下就按甲公司提出的条件发货，甲公司收货后未提出异议，亦未付货款。后因市场行情发生变化，该货物价格下降。甲公司遂向乙公司提出，由于双方未签订书面合同，该买卖关系不能成立，故乙公司应尽快取回货物。乙公司不同意甲公司的意见，坚持要求其偿付货款。随后，乙公司发现甲公司放弃其对控股子公司的到期债权，并向其控股子公司无偿转让了－批财产，可能使自己的货款无法得到足额清偿，遂向人民法院提出诉讼。

要求：

根据上述情形及有关法律规定，分析回答下列问题：

(1)

试述甲公司传真订货、乙公司报价、甲公司回复报价行为的法律性质。

(2)

该买卖合同是否成立?说明理由。

(3)

对甲公司放弃到期债权、无偿转让财产的行为，乙公司应向人民法院提出何种权利请求，以保护其利益不受损害?对乙公司行使该权利的期限，法律有何规定?

     When one of Ullman's grandsons, Jonas Rosenfield, Jr. was having dinner in Japan a few years ago,

"Youth" came up in conversation, Rosenfield told his dinner companion, a Japanese business leader, that

the author was his grandfather. The news was staggering.

     " 'You are the grandson of Samuel Ullman?' he kept repeating," says Rosenfield, head of the American Film Marketing Association. "He couldn't get over it."

     Then the executive pulled a copy of "Youth" from his pocket and told Rosenfield, "I carry it with me

always."

     Three years ago, several hundred top businessmen and government leaders gathered in Tokyo and

Osaka to celebrate their admiration of Ullman's "Youth". Konosuke Matsushita, founder of the Panasonic Company, said "Youth" has been his motto for 20 years."

     Someone asked, "Why don't Americans love "Youth" as much as we do? It sends a message about

how to live beautifully to men and women, old and young alike."

civil War and settled in Birmingham, Ala. He was a hardware businessman with a liking for public service

that continues 67 years after his death. In the last few years more than $36,000 from Japanese royalties (皇室) on a book and a cassette reading of his work has gone to a University of Alabama at Birmingham

scholarship fund. Not bad for a man who started writing in his 70s.
