听力原文： Three bombings in Baghdad Wednesday have left dozens of people dead and more than 70 others wounded. The attacks appear to have been coordinated to cause maximum civilian casualties.
The first explosion ripped through a parking garage at the al-Nahda bus station, shortly before eight, Wednesday morning, just as travelers were arriving and departing aboard buses, mini-vans and taxis.
The bus station is a major transit point for people traveling to predominantly Shi'ite cities to the south of the capital.
A distraught parking attendant at the station, Hussain Gateh, tells VOA that he did not know that he had allowed a suicide car bomber to go into the garage. Mr. Gateh says that a Kia-model car approached him just before eight o'clock. He says he gave the driver a ticket to park, not knowing what the bomber was about to do.
As huge plumes of black smoke filled the sky from the first explosion, a second bomb went off near the entrance to the bus station, killing and wounding dozens of people, who had by then gathered at the station in large numbers.
As ambulances ferried the dead and wounded to nearby al-Kindi hospital, a third bomb detonated near the building, killing some of those who had come to the hospital to help.
According to the news the bus station is a major transit point to ______.
What's the talk mainly about？
SECTION B PASSAGES
Directions: In this section, you will hear several passages. Listen to the passages carefully and then answer the questions that follow.
听力原文： It was an Italian inventor who created the first wireless device for setting out radio signals in 1895. But not until the American inventor Lee De Forest built the first amplifying vacuum tube in 1906 did we get the first radio as we know it. And the first actual radio broadcast was made on Christmas Eve of 1906. That's when someone working from an experimental station in Brand Rock, Massachusetts, arranged the program with two short musical selections of poem and brief holiday greeting. The broadcast was heard by wireless operators on ships with a radio through several hundreds miles. The following year, De Forest began regular radio broadcasts in New York. These programs Were similar to much what we hear on radio today. In that, De Forest played only music. But because there were still no home radio receivers, De Forest's audiences consisted only of wireless operators on ships in New York Harbor. There is no doubt that radio broadcasting was quite a novelty in those days, but it took a while to catch on commercially. Why？ Hmm, for the simple fact that only a few people, in fact, only those who tinkered with wireless telegraphs as a hobby owned receivers. It wasn't until the 1920s that someone envisioned mass appeal for radio. This was radio pioneer David Sarnoff who predicted that one day there would be a radio receiver in every home.
Why were early radio broadcasts heard by such a small audience？
