【题目】自然界有一种“雷雨发庄稼”的现象，即在雷雨过后，植物生长得更好。下面一段短文就是叙述雷雨中发生的一系列化学变化过程：

①空气中的N2在放电条件下与O2直接化合生成无色且不溶于水的一氧化氮气体；

②一氧化氮的密度比空气略大，不稳定，常温下就易与空气中的O2反应生成红棕色的二氧化氮气体；

③二氧化氮气体有毒，易与水反应生成硝酸(HNO3)和一氧化氮；

④生成的硝酸随雨水洒到大地上，同土壤中的矿物质相互作用，生成可溶于水的硝酸盐。

请填写下列空白：

(1)上述短文中，描述二氧化氮化学性质的是________(填序号)。

(2)实验室制取一氧化氮时，下列收集方法不适宜的是________。

A．向上排空气法

B．向下排空气法

C．排水收集法

(3)写出二氧化氮与水反应的化学反应方程式：____________________________________，其中氮元素的化合价在此反应中发生的变化是________。

A．不变 B．仅升高

A．生成的一氧化氮可以作为氮肥

B．生成的二氧化氮可以作为氮肥

C．生成的硝酸盐可以作为氮肥

【题目】A

Scientists and marine biologistshad(海洋生物学家) something to celebrate last week when two lost humpback whales(座头鲸) returned to the Pacific Ocean. Delta and Dawn ― a mother and a baby ― had circled the Sacramento Bay area for two weeks before going back to the ocean.

＂We all shouted loudly like ‘Yay’!＂said Jim Oswald, a spokesman for the Marine Mammal Center. ＂It’s been really exciting.＂

The humpback whales were last spotted on May 29 near the Golden Gate Bridge in San Francisco, California. Scientists are sure that the whales swam into open water during the evening of May 29 or early the next morning, since there have been no further sightings of the whales. Even so, boats were sent out to look for them, just in case the whales made another wrong turn.

Officials spent two weeks trying to get the whales to turn back towards the ocean. Biologists played recordings of whale-feeding as well as unfamiliar sounds to try to make the whales head back to the Pacific Ocean.

However, Delta and Dawn gave scientists an unexpected chance to study humpback whales in the wild. Scientists were able to gather sound recordings and watch their behaviors. This is especially exciting because humpback whales are an endangered species. What’s more, scientists don’t usually have the chance to observe (观察) them in their natural habitat.

＂All those things are very hard to get,＂ said Oswald,＂So what we are doing is filling up the knowledge blank on humpback whales in the wild. ＂ Scientists should be able to use this information to help other lost whales in the future.

A. the whales traveled to Sacramento Bay

B. the whales returned to the Pacific Ocean

C. the scientists held a great celebration

D. he found the lost humpback whales

【2】 In order to make the whales go back to the ocean, the biologists____________.

【3】 The fifth paragraph mainly tells us that____________.

A. humpback whales will disappear in the future

B. scientists are worried about humpback whales

C. humpback whales were excited in their natural habitat

D. scientists learned more about humpback whales

【4】What’s the best title for the passage?

A. Looking for the Lost Whales B. Helping the Lost Whales

C. The Lost Whales Returned D. Two Whales Were Lost
