炸药激发的地震振动是（）的似正弦脉冲，脉冲的前缘很陡，能量高度集中。 A.衰减很快

When you travel in South America, you’d better pay attention to the following three kinds of dangerous South American animals.

Piranhas（水虎鱼）

Although only a small number of piranhas are considered to be dangerous to humans, the red-bellied piranha is definitely one of those. Evidence has shown that a large group of piranhas can absolutely eat a herd of large animals crossing the river, leaving only bones. This fish lives in the freshwater streams of South America, and they can smell the blood from far away and launch attacks swiftly. It is said that they are only dangerous to humans if the water volumes are less and lower.

Anacondas（水蟒）

This South American monster of a creature often appears in the films or your nightmares！They have weighed over 230 kilograms. It is often considered to be the biggest snake in the world. You certainly don’t want to get caught alone with this snake due to its method of attacking and killing its victim. It is indeed a remarkably different brand of snake type as it regularly coils（缠绕）around all over its target, increasing the pressure until eventually its victim dies. Its jaws are powered by large muscles that produce enough power for its over 100 sharp teeth to pass through the thick skin of an crocodile. They don’t have poison. Sometimes they prefer to camouflage themselves so they look like their surroundings and swiftly draw back when humans are near.

Golden Poisonous Frogs

The golden poison frog might be the most-deadly of the South American animal, which is protected by means of poison. This very small frog, less than 55 mm in length, packs enough punch（效力）to take down a pair of African bull elephants. This apparently harmless frog has always been known to have killed people who have touched it directly. It’s also been noted that chicken and dogs have died by contacting things on which a golden poison frog had wandered! In intense colors, they normally look attractive to their targets.

A．Piranhas are the most dangerous animals.

B．Piranhas like to live in the deep seabed.

C．Piranhas may attack human beings when the water level is low.

A．It often uses its poison to kill its victim.

B．It often uses its strength to kill its victim.

C．It kills its victim mainly using its powerful teeth.

A．hide itself by appearing like the surroundings

B．terrify and capture the enemy by making much noise

C．move around to search for delicious food

D．give off harmful gas to kill the targets小题4:Chicken and dogs are mentioned in Paragraph 4 to show that ________.

个人应用一系列的认知操作，从问题的起始状态到达目标状态的过程，称为（）。

阅读下面的文言文，完成下面题。

　　王羲之,字逸少，司徒导之从子也。羲之幼讷于言，人未之奇。及长，辩赡，以骨鲠称。尤善隶书，为古今之冠，论者称其笔势，以为飘若浮云，矫若惊龙，深为从伯敦、导所器重。时陈留阮裕有重名，裕亦目羲之与王承、王悦为王氏三少。时太尉郗鉴使门生求女婿于导，导令就东厢遍观子弟。门生归，谓鉴曰：“王氏诸少并佳，然闻信至，咸自矜持。唯一人在东床坦腹食，独若不闻。”鉴曰：“正此佳婿邪！”记之，乃羲之也，遂以女 妻之。

　　羲之雅好服食养性，不乐在京师，初渡浙江，便有终焉之志。会稽有佳山水，名士多居之，谢安未仕时亦居焉。孙绰、李充等皆以文义冠世，并筑室东土与羲之同好。尝与同志宴集于会稽山阴之兰亭，羲之自为序以申其志。

　　性好鹅，会稽有孤居姥养一鹅，善鸣，求市未能得，遂携新友命驾就观。姥闻羲之将至，烹以待之，羲之叹惜弥日。又山阴有一道士，养好鹅，之往观焉，意甚悦，固求市之。道士云：“为写《道德经》，当举群相送耳。” 羲之欣然写毕，笼鹅而归，甚以为乐。尝至门生家，见篚几滑净，因书之，真草相半。后为其父误刮去之，门生惊懊者累日。羲之书为世所重，皆此类也。每自称：“我书比钟繇，当抗行；比张芝草，犹当雁行也。”曾与人书云：“张芝临池学书，池水尽黑，使人耽之若是，未必后之也。”

　　时骠骑 * * 王述少有名誉，与羲之齐名，而羲之甚轻之，由是情好不协。述先为会稽 ，以母丧居郡境，羲之代述，止一吊，遂不重诣。述每闻角声，谓羲之当侯己，辄洒扫而待之。

　　如此者累年，而羲之竟不顾，述深以为恨。（节选自《晋书·王羲之传》，有删改）
