问题 材料分析题

五花大米草原产于英国沿海,淤积能力强。我国在20世纪80年代引入东南沿海地区后,有大米草生长的沿海滩涂每年以100米以上的速度向海洋拓展。新淤积出来的土地含盐量太高,既不利于开垦为耕地,也不适合淡水养殖。大米草所到之处,滩涂上的生物几乎全部灭绝,还使海洋生物资源的数量和质量下降,影响沿海养殖区的生存与发展,港口也因此废弃。据此回答下列问题。

(1)对比英国沿海和我国东南沿海的自然环境特点,说明我国东南沿海的哪些自然条件使大米草生长繁盛。

___________________________________________________________________________________________

(2)适宜大米草分布的海岸地区一般具有哪些特征?大米草的生长使该海域的外力作用发生什么变化?

___________________________________________________________________________________________

(3)据资料说明大米草的生长使我国东南沿海地区的资源发生了哪些变化。

___________________________________________________________________________________________

(4)大米草的引进,导致我国东南沿海产生的环境问题是_________________。

答案

(1)英国沿海地区为温带海洋性气候,终年温和多雨;沿岸海水温度、盐度较中国东南沿海低。我国东南沿海主要为亚热带季风气候,夏季高温多雨,冬季温和少雨。夏季较高的气温和水温使大米草生长旺盛。

(2)近岸浅海水域或河流人海口附近,海水含沙量较大。海水的侵蚀作用减弱,堆积作用增强。

(3)淤积造陆,使土地面积增加;港口因此而废弃。海洋生物资源的数量和种类减少。

(4)生态破坏,生物多样性减少。

A couple of years ago, before a trip to China, Nicole Davis and her US women’s volleyball teammates were warned about the prominence (显著、突出) of coach “Jenny” Lang Ping in her native country.

“I was pushed over by Chinese journalists while I was just trying to put my luggage on the bus,” said Davis.

Known as the “Iron Hammer” for her punishing spikes(扣球), Lang made it possible for China to dominate in the sport in the early 1980s. She was a key player on China’s 1984 Olympic gold medal winning team.

When the US team arrived for the Olympics, Lang, 48, who is from Beijing, had to take a different route to avoid a crowd of reporters and fans.

Then came the greatest moment to Lang:while the US team was playing in a packed gym, at least 8,000 Chinese fans unfurled an American flag.

“That really says it all,” Davis said. “They look at her as an icon(偶像).I’m sure it’s hard for them to see her coaching another country, but they love her so deeply that her success is their success.”

The loyalty of the Chinese fans was tested on Friday, when China lost a match to the US.

“It’s a pity that China lost the match, but I’m still glad that Lang Ping’s team won, since she is the pride of China’s volleyball,” said Liu Chengli, a spectator. “We also cheered for Lang’s victory.”

Lang said she just tried to stay professional when the two teams meet. “It doesn’t matter if we play China or any other team. It’s the same.” Lang said.

Davis said she and her teammates could not have imagined the passion for volleyball among Chinese because the sport was lack of popularity in the US. The reception from Chinese fans has touched the US players, said a US volleyball player Lindsey Berg.

“It’s such an honor to be here and play for our coach here in China,” she said. “The amount of support that the Chinese give to her and us has been tremendous. The whole event has been unbelievable.”
