听力原文： Reports say Japan and US have reached an agreement on a dispute over air-cargo transport rights in Asia. The agreement means Washington and Tokyo will re-negotiate 1952 Aviation Treaty which allowed American airlines to fly on from Tokyo to other places of Asia but didn't allow Japanese airlines the same way to fly on from America to other destinations. Tokyo has always said that the treaty was unfair and Japan has always wanted it changed. According to the agreement, Japan will allow American airlines carrier Federal Express to fly on through Tokyo to seven other destinations in Asia. Now Japan has always said it was happy to allow that if the treaty was re-negotiated. It does seem very clear that Japan will come out of this one on top. This is certainly not the first dispute and certainly won't be the last dispute, either. There are several outstanding areas of friction between Japan and US. At the moment, they are negotiating about photographic film and photographic paper. It could take a year to resolve. But even where the two countries do reach an agreement, there is still room for argument. They reach the famous car agreement about a month ago. They are still bickering about it.

Japan and the United States are now

A．negotiating about photographic material.

B．negotiating an automobile agreement.

C．facing serious problems in trade.

D．on the verge of a large-scale trade war.
