PTE写作中的SWT题型怎么找关键句

今天羊驼给各位正在准备PTE考试的同学们带来了PTE考试中的SWT题型的例题解析：Tiny frog found in Mexico，在墨西哥发现的非常小的青蛙，这篇相对来说有点难度，很难找到主旨句，所以希望大家多花点时间，来找出主旨句。并不一定要看懂这篇文章到底在说什么，把最核心的东西抄下来，凑成65~72个字的一句话就可以了。

一、PTE写作SWT例题的原文：

A miner in the state of Chiapas found a tiny tree frog that has been preserved in amber for 25 million years, a researcher said. If authenticated, the preserved frog would be the first of its kind found in Mexico, according to David Grimaldi, a biologist and curator at the American Museum of Natural History, who was not involved in the find.The chunk of amber containing the frog, less than half an inch long, was uncovered by a miner in Mexico’s southern Chiapas state in 2005 and was bought by a private collector, who loaned it to scientists for study.A few other preserved frogs have been found in chunks of amber - a stone formed by ancient tree sap - mostly in the Dominican Republic. Like those, the frog found in Chiapas appears to be of the genus Craugastor, whose descendants still inhabit the region, said biologist Gerardo Carbot of the Chiapas Natural History and Ecology Institute. Carbot announced the discovery this week.The scientist said the frog lived about 25 million years ago, based on the geological strata where the amber was found.Carbot would like to extract a sample from the frog’s remains in hopes of finding DNA that could identify the particular species but doubts the owner would let him drill into the stone.

二、PTE写作SWT例题的答案：

A tiny tree frog preserved in amber for 25 million years has been found, and the preserved frog would be the first of its kind found in Mexico, and a few other preserved frogs have been found in chunks of amber, and Carbot would like to extract a sample from the frog's remains in hopes of finding DNA that could identify the particular species but doubts the owner would let him drill into the stone.

三、PTE写作SWT例题的翻译：

A miner in the state of Chiapas found a tiny tree frog that has been preserved in amber for 25 million years, a researcher said.

一位研究人员称，美国恰帕斯州的一位矿工在琥珀中发现了一只被保存了2500万年的小树蛙。

If authenticated, the preserved frog would be the first of its kind found in Mexico, according to David Grimaldi, a biologist and curator at the American Museum of Natural History, who was not involved in the find.

美国自然历史博物馆(American Museum of Natural History)生物学家兼馆长戴维?格里马尔迪(David Grimaldi)表示，如果能被证实，这只保存下来的青蛙将是在墨西哥发现的首只同类青蛙。格里马尔迪没有参与此次发现。

The chunk of amber containing the frog, less than half an inch long, was uncovered by a miner in Mexico’s southern Chiapas state in 2005 and was bought by a private collector, who loaned it to scientists for study.

2005年，墨西哥南部恰帕斯州的一名矿工发现了含有这只青蛙的琥珀，后来被一位私人收藏家买下，并借给科学家研究。

A few other preserved frogs have been found in chunks of amber - a stone formed by ancient tree sap - mostly in the Dominican Republic.

在琥珀中还发现了其他一些保存完好的青蛙，大部分在多米尼加共和国。琥珀是由古代树液形成的石头。

Like those, the frog found in Chiapas appears to be of the genus Craugastor, whose descendants still inhabit the region, said biologist Gerardo Carbot of the Chiapas Natural History and Ecology Institute.

恰帕斯自然历史与生态研究所的生物学家吉拉尔多?卡尔特说，与那些青蛙一样，在恰帕斯发现的青蛙似乎属于克拉加斯特属，其后代仍居住在该地区。

Carbot announced the discovery this week.

卡特本周宣布了这一发现。

The scientist said the frog lived about 25 million years ago, based on the geological strata where the amber was found.

根据发现琥珀的地质地层，这位科学家说，这只青蛙生活在大约2500万年前。

Carbot would like to extract a sample from the frog’s remains in hopes of finding DNA that could identify the particular species but doubts the owner would let him drill into the stone.

卡特想从这只青蛙的遗体中提取样本，希望能找到DNA，以确定这一特殊物种，但他怀疑青蛙的主人会让他在石头上钻孔。

四、PTE写作SWT例题的解析：

1、Tiny folk founding Mexico, 首先第一段告诉你发生了什么事情，就是在这个地方，发现一个非常小的树蛙，这是最重要的。然后把它的重要性说出来，The three would be the first of its kind found in Mexico, 那么如果经过证实的话，这个青蛙很有可能是墨西哥发现的这个种类当中第一个。

2、下一段最后这个Carbot提了2次，那么提了2次的东西，我觉得还是有必要写一写的。所以最重要的这一篇当中发生什么事情，讲的是发现了一个树蛙。第二个什么事情，这个说法很重要，重要点在哪里？第三个事情，把这三个最重要抄下来，把Carbot这个人抄下来，凑到65~72个字，这道题就解决了。所以SWT并不一定是要看懂这篇文章到底在说什么，你把最核心的东西抄下来。因为本来这道题就叫做summarize，Summarize written test给出一个文本，你去summarize它。那么把最主旨最核心的东西抄出来，那这道题你就拿下了。
