       “Have you ever been on a surfboard or boat and felt yourself being lifted up by a wave?

Which of the following is NOT true?

       A．Wave power doesn’t cost too much money．

       B．Wave energy is so clean that it doesn’t create the same amount of pollution as other energy sources．

       D．Wave power may affect marine animals．

We can infer from the passage that ______．

       A．finding more new energy sources is not necessary because of wave energy

【小题1】Which of the following is NOT true?

A New Zealand volcano dormant for more than a century has erupted，sending up ash clouds，disturbing flights and closing roads．
Mount Tongariro, one of three volcanoes in the centre of the North Island, became active just before midnight local time, with reports of loud explosions，pouting rocks and steam.
The 1, 978m peak is in a national park popular with hikers. No damages have been reported after the eruption.
Witnesses described a dramatic scene as the volcano erupted.
“I saw this beautiful. big cloud and I thought: ‘Gee that looks like a volcanic plume’. Just as I thought that there was a great big orange flash,” truck driver Bryn Rodda told New Zealand National Radio. “It was quite impressive.”
Mount Tongariro last erupted 115 years ago. And scientists said they did not yet know if this eruption was a single event.
Experts said they were caught by surprise—they had recorded some activity like an earthquake in recent weeks but were not expecting an eruption．
“This might just be a quiet period and we should expect it to start again at any time. So we are watching things Very closely,” volcanologist Michael Rosenberg told TVNZ.
Eruption activity has currently reduced, New Zealand media said．Meteorologists(气象学家)said the ash was blowing east towards the Pacific Ocean.
A number of inland flights from the North Island to the South Island had been affected by the volcanic activity, Air New Zealand said.
Police said highways that had been closed because visibility was affected after the eruption are now open.
Some residents in the nearby areas had temporarily left their homes. Officials have not ordered an evacuation(撤离), but advised those affected by the ash cloud to stay indoors and close their doors and windows.
