The Labor Department says that immigrants make up about 15 percent of the work force. It’s estimated that a third of those are undocumented workers.

[单项选择]People can get emotional about immigration. Bill O’Reilly, a talk-show host, devoted a recent segment to the story of an illegal alien who got drunk and accidentally killed two attractive white girls with his car. If only he had been deported for previous misdemeanours, Mr. O’Reilly raged, those girls would still be alive. Another talk-show host, Geraldo Rivera, during an on-air shout-joust(争吵) with Mr. O’ Reilly, denounced his demagogic choice of story-angle as" a sin".
President George Bush tried again this week to bring a more rational tone to the debate. He urged the new Democratic Congress to revive the immigration reforms that the old Republican Congress killed last year. His proposal was broadly the same as before. He said he wanted to make it harder to enter America illegally, but easier to do so legally, and to offer a path to citizenship for the estimated 12m illegals who have already snuck in.

A. severe crimes.

I want to talk today about some studies. They seem to indicate that there is a startling world-wide decline in the number of amphibians, such as flogs, toads and salamanders. There’s little doubt that one reason why the number of amphibians is declining is their habitats have been destroyed when the developers fill in ponds and marshes to build houses. Amphibians can’t just move somewhere. They need water to lay their eggs in. Another problem is the growing fish industry. Another range of popular pool fish such as carp have been introduced to many lakes and ponds all over the world. Raising and selling these fish can be profitable, but the fish eat the eggs and offspring of amphibians that were already living in the lakes and ponds. Other factors could be contributing to the decline include acid rain and the spread of pesticide residues. Many pesticides that farmers added to their crops are eventually washed away bythe rain and end upin pondsand other bodies of water

Some of the concerns surrounding Turkey’s application to join the European Union, to be voted on by the EU’s Council of Ministers on December 17th, are economic—in particular, the country’s relative poverty. Its GDP per head is less than a third of the average for the 15 pre-2004 members of the EU. But it is not far off that of one of the ten new members which joined on May 1st 2004 (Latvia), and it is much the same as those of two countries, Bulgaria and Romania, which this week concluded accession talks with the EU that could make them full members on January 1st 2007.
Furthermore, the country’s recent economic progress has been, according to Donald Johnston, the secretary-general of the OECD, "stunning". GDP in the second quarter of the year was 13.4% higher than a year earlier, a rate of growth that no EU country comes close to matching. Turkey’s inflation
