听力原文： The dollar dipped against the euro and the yen on Monday in the wake of weak U. S. jobs data, although the euro remained vulnerable due to worries about the political and economic outlook of the European Union.
The greenback was sold off after weak U.S. jobs figures on Friday but the euro remained close to 8-month lows after France and the Netherlands rejected the EU constitution in referendums last week.
"It's been one-way news in favor of the dollar apart from Friday's job data... We're seeing a bit of a move back today but it's not that convincing. Such is the weight of bad news on the euro," said Ian Gunner, head of foreign exchange research at Mellon Bank.
U.S. jobs growth in May was the worst in 21 months, data showed on Friday, coming after figures last week showed manufacturing activity was the slowest in almost two years.
By 0750 GMT, the euro stood at $1.2266 against the dollar, up a quarter of a percent from late New York levels on Friday and a cent above last week's 8-month low of $1.2157. The euro was little changed against the yen.
The dollar was also down a quarter of a percent against the yen at 107.29 yen.
Eurozone finance ministers meet in Luxembourg on Monday and Tuesday in the face of uncertainty over further European political and monetary integration following the two "no" votes.
Rejection of the charter at the referendums, along with the region's poor growth prospects, helped push the euro down almost 3 percent against the dollar last week.
Britain's foreign secretary was expected to announce on Monday the country was shelving plans for a referendum on the EU constitution, one step short of publicly declaring it dead.
The euro wobbled after European Central Bank Chief Economist Otmar Issing was quoted as saying that policy strategy does not rule out an interest rate cut.
A cut in rates would further underscore the dollar's interest rate advantage over the euro. U.S. rates stand at 3.0 percent compared to 2.0 percent in the euro zone.
According to the news item, ______.
A．both the dollar and the euro were strong
B．both the dollar and the euro were weak
C．the dollar was strong while the euro was weak
D．the dollar was weak while the euro was strong

They are said to be reluctant to forsake the pleasures of single life. But nothing could be further from the truth; British women are much more attached to marriage than their European counterparts, around 95.1 percent of British women have married at least once by age 49, the highest figure in the European Union. Only 91.2 percent of British men have walked up the aisle by the same age.
Meanwhile, the much discussed trend for delaying marriage until later in life--blamed on career women reluctant to have children--may actually reflect a return to the historical norm.
The average age of first marriage in Europe 200 years ago was 28, the same as British brides in 1998, according to a paper for the National Family and Parenting Institute, the independent thinktank set up by Jack Straw to advise on family issues.
"The public conversation about marriage has often been conducted in an atmosphere fraught with anxiety that can easily tip over into what commentators have described as a moral panic," the report, comparing European trends in marriage, adds.
"Changes in the marriage rate and in the way people form. relationships are part and parcel of a society where change is rapid and individuals feel helpless in the face of new developments; yet it is vital that these issues can be discussed without blame."
The paper does not include divorce rates. In 1997 Britain had the highest divorce rate in Europe, although by 1999 the rate had fallen to the level of the late 1980s.
Despite much political consternation about the family, the report suggests British attitudes are more socially conservative than those of many EU counterparts.
Nine out of 10 couples in Britain living with their children are married, compared to half in Finland. And while cohabiting is becoming the norm for European twentysomethings, "change has happened much more rapidly across the whole of the EU than in the UK", the report finds. Around a third of British under-thirties live with a partner, but it is closer to half in France and 40 per cent in Germany.
"This report is about let's bring a cool head to this debate," said Gill Keep, head of policy at the institute. "It is much easier to take the panic out of the discussion if you look at it in a comparative way; things that you think are destroying your own society are actually common trends and they may not be that destructive."
She said that despite anxiety over later marriages--the average age of first-time brides rose from 23 in the postwar period to 28 for women and 30 for men by 1999--historically this would have seemed normal.
Social historian Christina Hardyment said that in the nineteenth century couples would not marry until they could afford to support a household. "Women below the middle classes would always work in some capacity, mainly in domestic service, and it made sense to save; people think of kings and queens and nobility being married off at 12 but that was highly unusual," she said.
It is a well-known fact that British women are unwilling to abandon single life for a marriage.
A．True
B．False
