问题 读图填空题

(4分)近半年来,黄山周边松树陆续发生零星、小块状枯死现象。经技术人员实地调查和镜检分析,发现松树枯死的原因主要松材线虫病传播媒介昆虫――“松褐天牛”危害所致。为有效遏制松褐天牛对国宝“黄山松”的危害,黄山区此次从江苏林科院林保所引进了70万只“管式肿腿蜂”,“管式肿腿蜂”在“松褐天牛”的卵上产卵,后者的幼虫会成为幼蜂的美餐,因此对于防治松褐天牛保护黄山松起到了很好的作用。

(1)黄山 “迎客松”迎来了八方游客,松树属于(    )

A.被子植物   B.裸子植物    C.藻类植物     D.蕨类植物

(2)管式肿腿蜂的幼蜂与松褐天牛幼虫的关系是(    )

A.竞争         B.寄生         C.捕食       D.共生

(3)用管式肿腿蜂防治松褐天牛的方法属于(    )

A.克隆       B.生物防治     C.转基因       D.生物反应器

(4)松褐天牛的发育与管式肿腿蜂一样都经历“蛹”期,因此属于             发育。

答案

(1)B(2)C (3)B(4)完全变态

考点:

分析:此题是一个综合性的填空题,涉及裸子植物的特征、生物之间的关系、生物防治、动物的发育等知识,逐一分析解答.

解答:解:(1)、松树的种子外无果皮包被着,裸露,属于裸子植物.故选:B

(2)、分析题意可知,管式肿腿蜂的幼蜂以松褐天牛幼虫为食,属于捕食关系.故选:C

(3)、生物防治就是利用一种生物对付另外一种生物的方法.生物防治,大致可以分为以虫治虫、以鸟治虫和以菌治虫三大类.它是降低杂草和害虫等有害生物种群密度的一种方法.它利用了生物物种间的相互关系,以一种或一类生物抑制另一种或另一类生物.它的最大优点是不污染环境,是农药等非生物防治病虫害方法所不能比的.用管式肿腿蜂防治松褐天牛的方法就属于生物防治.

(4)、松褐天牛的发育与管式肿腿蜂一样都经历了卵、幼虫、蛹、成虫四个时期,其幼体和成体的形态结构和生活习性都发生了很大的变化,叫完全变态发育.

故答案为:(1)B(2)C (3)B(4)完全变态

点评:此题涉及的知识面比较广,这就要求我们要熟练掌握相关的基础知识,才能灵活答题.

Passage Three

Her Dual Citizenship Brings Prejudice
她的双重国籍导致了偏见

She is Vietnam’s top-ranked female tennis player.Still,Noel Huynh Mai Huynh is criticized by the state-run press and jeered by Vietnamese crowds who do not accept her as one of their own.
"I play tennis for my family,"Huynh said before the Southeast Asian Games,a regional
competition that runs through Saturday."There’s a lot of pressure because I know a lot of people, they don’t like me very much."
Huynh,18,was born in the US territory of Guam.She is the first"Viet kieu."or overseas Vietnamese,to receive dual citizenship from the Vietnam government to compete for Vietnam.
Huynh was four years old when her family moved back to Ho Chi Minh City(formerly Saigon) in 1989.She did not speak Vietnamese then but has since mastered the language and now considers herself more Vietnamese than American.
Still,many are wary.She is thought of as spoiled because of her American passport.It doesn’t seem to matter that she’s never been on the US mainland.
She and her four siblings—all accomplished tennis players—have been passed over for less talented Vietnamese players.
"We practice in Vietnam,we grew up in Vietnam...and they cannot beat us so they try to keep us out of competitions so we don’t beat them,"said brother,Jean-Pierre Qui Phu Huynh Jr.
The 65-year-old family patriarch,also named Jean-Pierre,is their inspiration.In perfect English,he recounts the path that led him from Vietnam in 1975 and back 14 years later.
He fought for the US-backed South Vietnamese army and was the tennis coach for former President Nguyen Van Thieu.He put his wife and children on one of the last helicopters leaving the US Embassy before Saigon fell April 30,1975.He spent the next six months searching for his family,finding them in California.
They moved to Guam,where French.educated Jean-Pierre became a top tennis player with a big house and booming business building tennis coups.Still,something was missing.So he decided to go home in 1987.
The family,all US citizens,returned to Vietnam two years later.Most refugees were too scared to think of visiting them.
The elder Huynh coached his children up to eight hours a day,six days a week,and tried to make sure they got to play.
He became friends with former Prime Minister Vo Van Kiet,a tennis fan,and built the country’s largest tennis complex in Ho Chi Minh City.He brought in international tennis competitions and urged Vietnam to strengthen its national team.Still,the discrimination persisted.
"I don’t care about anybody who cheers for the other player,"his daughter said."It’s OK for me,but sometimes I’m kind of sad about that because I’m on the national team but thev alwavs want the other players to beat me."
With Vietnam hosting the Southeast Asian Games for the first time and encouraging about 2.5 million Viet kieu to return,she was given a chance at this event.
"With the participation of Huynh Mai Huynh,the Vietnamese tennis team will be per," said Nguyen Hong Minh,head of the Vietnamese SEA Games sports delegation."This is in our policy to expand international relations as well as win the support of the overseas Vietnamese community."
She was eliminated from doubles and mixed doubles.Her strength is singles.but she said her
coaches didn’t select her for that event.
Huynh says all she wants is to represent the country she considers home.
"I’ll stay here,"she said,"and I’ll play for Vietnam forever."

The reason for Jean-Pierre,the family patriarch,to decide to go home with family is mostly likely that______.

A.the family was hard up in a foreign country

B.he couldn’t find what he liked in Guam

C.his children wanted him to take them home

D.he is emotionally attached to his own country
