Scientists have long puzzled over how iguanas, a group of lizards(蜥蜴) mostly found in the Americas, came to live in the isolated Pacific islands of Fiji and Tonga. Some scientists used to suppose that they must have traveled there on a raft, a journey of around 5,000 miles from South America to the islands. There are documented cases of iguanas reaching remote Caribbean islands and the Galapagos Islands on floating logs. But new research in January by Brice Noonan and Jack Sites suggested that iguanas may have simply walked to Fiji and Tonga when the islands were still a part of an ancient southern supercontinent.

The ancient supercontinent was made up of present-day Africa, Australia, Antarctica and parts of Asia. If that’s the case, the island species would need to be very old. Using “molecular (分子) clock” analysis of living iguanas’ DNA, Noonan and Sites found that, sure enough, the lineage of iguanas has been around for more than 60 million years—easily old enough to have been in the area when the islands were still connected by land bridges to Asia or Australia.

Fossils (化石) uncovered in Mongolia suggest that iguanid ancestors did once live in Asia. Though there’s currently no fossil evidence of iguanas in Australia, that doesn’t necessarily mean they were never there. “The fossil record of this continent is surprisingly poor and cannot be taken as evidence of true absence,” the authors write.

So if the iguanas simply walked to Fiji and Tonga from Asia or possibly Australia, why are they not also found on the rest of the Pacific islands? Noonan and Sites say fossil evidence suggests that iguana species did once inhabit other islands, but went extinct right around the time when humans settled in those islands. But Fiji and Tonga have a much shorter history of human presence, which may have helped the iguanas living there to escape extinction.

The researchers say that their study can’t completely rule out the rafting theory, but it does make the land bridge theory “far more reasonable than previously thought.”

1. What did some scientists previously believe about the iguanas?

A. They were once discovered in America.

B. They traveled by raft to Fiji and Tonga.

C.  They could survive in poor living conditions.

D. They moved to Fiji and Tonga from Australia.

2.According to Noonan and Sites, 60 million years ago ____.  　

A. the land of the world was a supercontinent  　

B. Fiji and Tonga were connected to Asia or Australia

C. Africa, Australia and America were a continent

D. iguanas walked to Fiji and Tonga from Africa

3.The underline word “lineage” in Paragraph 2 probably refers to ____.

A. conditions in which creatures can survive

B. the change in ancient plants and animals.

C. the line of generations of an ancestor　　

D. the habitat of a type of an ancient animal　

4. What is the main topic of this passage?  　

A. The life span of animals living on the ancient supercontinent.　

B. The two islands being home to several iguana species in the Pacific region.

C. The fossil evidence suggesting iguanas’ ancestors’ swimming to Fiji and Tonga

D. By raft or by land — how did iguanas reach the tiny Pacific islands?

EU members' states have agreed to ban a toxic substance widely found in clothing because it poses an ''acceptable risk'' to the environment. Countries voted in favor of extending existing restrictions on nonylphenol ethoxylates (NPE) to imports to clothing and other textile products.

The measure is intended to protect species in water. Use of NPE in textile manufacture in Europe was banned over 10 years ago but the substance is still released into the water environment through imported textiles being washed.

NPE degrades in the environment into substances including nonylphenol (NP), which accumulates in the bodies of fish and disturbs their hormones, harming fertility, growth and sexual development.

NPE is used in textile manufacture as a cleaning and dyeing agent. The EU decision notes that several studies have found NPE to be present in textile items.

A 2011 study by Greenpeace found NPE in two-thirds of clothes tested, including items sold by big-name brads such as Adidas, H&M, Lacoste, and Ralph Lauren. The NGO (Non-Governmental Organizations) argued that although concentrations of NPE found in the clothes were low, the chemical’s existence in the environment posed a risk.

The new ban on textiles containing NPE in concentrations equal to or greater than 0.01% will enter into force five years after it is adopted by the European Commission, which is likely to happen in September.

In comments submitted to ECHA (European Chemicals Agency), clothing and textile firms have warned that obeying the restriction will be difficult because NPE ubiquitous in the supply chain and has numerous uses.

The new restriction will not apply to second-hand goods or recycled textiles because it is assumed that these will already have been washed several times so they contain negligible(微不足道的)amounts of NPE.

EU countries must eliminate pollution of water bodies by NP as it is a priority substance under the Water Framework Directive. A 2013 study by the UK environment agency warned that emissions from textiles could prevent progress towards this objective. It found 29% of imported cotton underwear contained NPE, which was released during the first two washes by the consumer.

1.The 2011 study by Greenpeace found _________.

A.29% of imported cotton underwear contained NPE

B.NPE had limited effects on aquatic species

C.NPE was widely present in textile products

D.clothes of good quality had no concentrations of NPE

2.What's the possible meaning of the underlined part ''ubiquitous'' in Paragraph 7?

A.is legally protected B.is not easy to be found

C.seems to be every where D.is uncommon

3.What can we learn from the text?

A.The original ban on use of NPE was very effective.

B.Recycled textile contain less NPE.

C.The new ban on imports of textile has come into force.

D.The UK environment agency is optimistic about the new ban.

4.Which section of the website does the text come from?

A.lifestyle B.technology.

C.Business. D.Environment.
