听力原文： The United States has recorded another huge monthly trade deficit. Figures for June show that import of goods exceeded export by more than 15,700 million dollars. This is nearly 2,000 million dollars more than the deficit in May due to an increase in import of oil and other goods. A BBC economics correspondent says the figures came as a shock since they have been compiled on the new basis which led everyone to expect they would seem far better. The deficit for the previous June was in fact slightly higher, but this was under the old system. The news immediately led to the dollar falling on the currency markets and our correspondent said that more seriously it would do nothing to curb the pressure within the American Congress for more protectionist legislation designed to keep foreign good out.
