Question

Where do the turtles go?

Every summer, thousands of endangered green sea turtles climb onto beaches around the world. Each mother sea turtle produces 100 or more eggs in a hole, and covers the hole with sand before she swims away.

Two months later, the eggs hatch(孵化), and the baby turtles climb out of the sand and swim into the ocean. They don’t reappear until they have grown as large as dinner plates. Until now, no one knows where the baby turtles go or what they do.

“if we don’t know where these little turtles are, we can’t protect them,” says Kim Reich, who helps solve part of the mystery.

Her teacher, Karen Bjorndal, has studied green sea turtles for more than 30 years. Every year, Bjorndal goes to the Bahamas Islands. Many young sea turtles come here to live and eat at the end of their childhood.

These turtles are the only sea turtles that live as plant eaters. In fact, their name may be a result of what they eat. The turtles don’t look green but they do have green fat. Scientists learned that the turtles eat green sea plants, which may turn their fat green.

Between 2002 and 2004, Bjorndal caught 44 green sea turtles in the Bahamas. After testing them, she found something to support the 20-year-old idea: baby green sea turtles eat meat before they turn to a diet of plants. In fact, they eat animals that live in the open ocean.

Scientists still need to find where exactly green sea turtles grow. We now know that baby green sea turtles are out in the open ocean, but the open ocean is a big place.

“It is really a problem,” says Bjorndal. The discovery may help us do a better job of protecting this sea animal.

【解析】

试题分析：本文是一篇说明文，每年夏天成千上万的濒临灭绝的绿海龟爬上沙滩，科学家在寻找它们到底去了哪里，以便可以保护它们。

1.B 理解理解题 根据第一段最后一句话“Each mother sea turtle produces 100 or more eggs in a hole, and covers the hole with sand before she swims away.”可以知道，龟妈妈产蛋之后会离开蛋。所以答案选B。

2.C 细节理解题 根据最后一段最后一句“The discovery may help us do a better job of protecting this sea animal.” 可以知道，这种发现可以更好地保护这种动物。

3.B 细节理解题 根据第六段第二句话“After testing them, she found something to support the 20-year-old idea: baby green sea turtles eat meat before they turn to a diet of plants. 测试之后，她发现一些支持20年前的一个观点：幼儿绿色龟在吃植物之前是吃肉的。”所以答案是选B。

4.段意思“Scientists still need to find where exactly green sea turtles grow. We now know that baby green sea turtles are out in the open ocean, but the open ocean is a big place. 科学家们仍然需要找到绿海龟成长的地方。我们现在知道，婴儿绿海龟是大海里，但大海是一个很大的地方。” 这两句话“We now know that baby green sea turtles are out in the open ocean, but the open ocean is a big place.”是对前面的补充，也就是 It指代的是find where exactly green sea turtles grow，所以答案选A。

【名师点睛】

阅读理解的解题方法有多个，就这篇文章我们就只点拨It的指代题。希望同学们掌握。

代词one，it，that，he，him或them等在英语文章中使用频繁，可以指上文提到的人或事物。有时代词与指代的对象相隔较远，要认真查找；有时需要对前面提到的内容进行总结，才能得出代词所指代的事。

代词回指和下指现象在英语语篇中极为常见，它们的运用，使文章前后衔接，意义连贯。

1、下指照应 指代对象出现在下文，代词位于前面与之发生照应关系，这就是下指照应。阅读时，正确判断下指代词所指对象，可以顺利地沟通上下文的语义关系，使阅读进行得顺畅。

2、回指照应 凡是指代对象出现在上文，代词位于后面与它形成照应关系，这就是回指照应。代词回指可以避免语言重复，使语言表达经济化，它比下指照应运用广泛，读者也容易辨识。代词回指这一语言现象也有其自身的某些特点，因此在阅读中也会出现许多难以理解的地方。

比如：本文中的第27题是属于回指照应。根据It前的一段意思“Scientists still need to find where exactly green sea turtles grow. We now know that baby green sea turtles are out in the open ocean, but the open ocean is a big place. 科学家们仍然需要找到绿海龟成长的地方。我们现在知道，婴儿绿海龟是大海里，但大海是一个很大的地方。” 这两句话“We now know that baby green sea turtles are out in the open ocean, but the open ocean is a big place.”是对前面的补充，
