托福TPO，英文名为TOEFL Practice Online，中文直译为托福线上练习，实际上是托福出卷机构ETS官方提供的一种付费服务，但每报考一次托福就会附送一份TPO服务，只要在自己的托福报名账号内使用即可。现在有不少没有经过授权的TPO,在网上可以搜索到。

TPO1-2 套，可以用来进行水平测试：

如果你初接触托福，那么你需要先从托福的 OG 开始了解一下托福究竟考什么，在了解清楚托福整个考试流程以及基本题型之后，先不要着急就开始单项的练习。建议大家使用 TPO1-2来进行模考，能够对托福考试的题型设置以及时间控制有大致的了解，并且通过模考了解自己听说读写四项能力，明确之后的复习中需要单独突破哪些方面。

TPO3-19套，可以用来进行单项突破：

水平测试之后根据自己在四个单项的分数以及个人是否适应的感觉来确定之后单项突破的计划。

如何使用TPO练习托福阅读：

1.模考完 TPO1-2 的阅读(每套题按规定时间 60 分钟做完)之后，

1)把里面所有不认识的核心单词查出来，背熟;

2)之后把整篇文章全都翻译一遍，然后对比一下译文，看看自己到底哪里理解错误;

3)接着将每一道题，而不仅仅是做错的题目，分析到底原文是怎么说，以及原文到底哪一句话得出了这道题的正确答案，如果是这道题你做错了你还要弄清一开始你为什么把这道题做错了，当时你是怎么理解的。

托福阅读原文

In 1970 geologists Kenneth J.Hsu and William B.F. Ryan were collecting research data while aboard the oceanographicresearch vessel Glomar Challenger.Anobjective of this particular cruise wasto investigate the floor of theMediterranean and to resolve questions aboutits geologic history. One questionwas related to evidence that theinvertebrate fauna (animals without spines) ofthe Mediterranean had changedabruptly about 6 million years ago. Most of theolder organisms were nearlywiped out, although a few hardy species survived. Afew managed to migrate into the Atlantic.Somewhat later, the migrants returned,bringing new species with them. Why didthe near extinction and migrationsoccur?

Another task for the GlomarChallenger’sscientists was to try to determine the origin of the domelikemasses buried deepbeneath the Mediterranean seafloor. These structures had beendetected yearsearlier by echo-sounding instruments, but they had never beenpenetrated in thecourse of drilling. Were they salt domes such as are commonalong the UnitedStates Gulf Coast, and if so, why should there have been somuch solidcrystalline salt beneath the floor of the Mediterranean?

With question such as these clearly beforethem, thescientists aboard the Glomar Challenger processed to the Mediterraneantosearch for the answers. On August 23, 1970, they recovered a sample. Thesampleconsisted of pebbles of hardened sediment that had once been soft,deep-seamud, as well as granules of gypsum and fragments of volcanic rock. Nota singlepebble was found that might have indicated that the pebbles came fromthenearby continent. In the days following, samples of solid gypsumwererepeatedly brought on deck as drilling operations penetrated theseafloor.Furthermore, the gypsum was found to possess peculiarities ofcomposition andstructure that suggested it had formed on desert flats. Sedimentabove andbelow the gypsum layer contained tiny marine fossils, indicatingopen-oceanconditions. As they drilled into the central and deepest part oftheMediterranean basin, the scientists took solid, shiny, crystalline saltfromthe core barrel. Interbedded with the salt were thin layers of whatappeared tobe windblown silt.

The time had come to formulate ahypothesis. The investigators theorized that about 20 million years ago, theMediterranean wasa broad seaway linked to the Atlantic by two narrow straits.Crustal movements closedthe straits, and the landlocked Mediterranean began toevaporate. Increasingsalinity caused by the evaporation resulted in theextermination of scores ofinvertebrate species. Only a few organisms especiallytolerant of very saltyconditions remained. As evaporation continued, the remainingbrine (salt water)became so dense that the calcium sulfate of the hard layerwas precipitated. Inthe central deeper part of the basin, the last of the brineevaporated toprecipitate more soluble sodium chloride (salt). Later, under theweight ofoverlying sediments, this salt flowed plastically upward to form saltdomes.Before this happened, however, the Mediterranean was a vast desert 3,000metersdeep. Then, about 5.5 million years ago came the deluge. As a result ofcrustaladjustments and faulting, the Strait of Gibraltar, where theMediterranean nowconnects to the Atlantic, opened, and water cascadedspectacularly back intothe Mediterranean.Turbulent waters tore into thehardened salt flats, brokethem up, and ground them into the pebbles observed inthe first sample taken bythe Challenger. As the basin was refilled, normalmarine organisms returned.Soon layer of oceanic ooze began to accumulate abovethe old hard layer.

Thesalt and gypsum, the faunal changes, and the unusualgravel provided abundantevidence that the Mediterranean was once a desert.
