By the end of the century，if not sooner，the world’s oceans will be bluer and greener thanks to a warming climate，according to a new study.

At the heart of the phenomenon lie tiny marine microorganisms(海洋微生物) called phytoplankton. Because of the way light reflects off the organisms，these phytoplankton create colourful patterns at the ocean surface. Ocean colour varies from green to blue，depending on the type and concentration of phytoplankton. Climate change will fuel the growth of phytoplankton in some areas，while reducing it in other spots，leading to changes in the ocean's appearance.

Phytoplankton live at the ocean surface，where they pull carbon dioxide(二氧化碳) into the ocean while giving off oxygen. When these organisms die，they bury carbon in the deep ocean，an important process that helps to regulate the global climate. But phytoplankton are vulnerable to the ocean's warming trend. Warming changes key characteristics of the ocean and can affect phytoplankton growth，since they need not only sunlight and carbon dioxide to grow，but also nutrients.

Stephanie Dutkiewicz，a scientist in MIT's Center for Global Change Science，built a climate model that projects changes to the oceans throughout the century. In a world that warms up by 3℃，it found that multiple changes to the colour of the oceans would occur. The model projects that currently blue areas with little phytoplankton could become even bluer. But in some waters，such as those of the Arctic，a warming will make conditions riper for phytoplankton，and these areas will turn greener. “Not only are the quantities of phytoplankton in the ocean changing. ”she said，“but the type of phytoplankton is changing. ”

1.What are the first two paragraphs mainly about?

A. The various patterns at the ocean surface.

B. The cause of the changes in ocean colour.

C. The way light reflects off marine organisms.

D. The efforts to fuel the growth of phytoplankton.

2.What does the underlined word “vulnerable” in Paragraph 3 probably mean?

A. Sensitive. B. Beneficial

C. Significant D. Unnoticeable

3.What can we learn from the passage?

A. Phytoplankton play a declining role in the marine ecosystem.

B. Dutkiewicz's model aims to project phytoplankton changes

C. Phytoplankton have been used to control global climate

D. Oceans with more phytoplankton may appear greener.

4.What is the main purpose of the passage？

A. To assess the consequences of ocean colour changes

B. To analyse the composition of the ocean food chain

C. To explain the effects of climate change on oceans

D. To introduce a new method to study phytoplankton

The traditional tent cities at festivals such as Glastonbury may never be the same again. In a victory of green business that is certain to appeal to environmentally-aware music-lovers, a design student is to receive financial support to produce eco-friendly tents made of cardboard that can be recycled after the bands and the crowds have gone home.

Major festivals such as Glastonbury throw away some 10,000 abandoned tents at the end of events each year. For his final year project at the University of the West of England, James Dunlop came up with a material that can be recycled. And to cope with the British summer, the cardboard has been made waterproof.

Taking inspiration from a Japanese architect, who has used cardboard to make big buildings including churches, Mr. Dunlop used cardboard material for his tents, which he called Myhabs.

The design won an award at the annual New Designers Exhibition after Mr. Dunlop graduated from his product design degree and he decided to try to turn it into a business.

To raise money for the idea, he toured the City’s private companies which fund new business and found a supporter in the finance group Mint. He introduced his idea to four of Mint’s directors and won their support. Mint has committed around £500,000 to MyHab and taken a share of 30 per cent in Mr. Dunlop’s business. The first Myhabs should be tested at festivals this summer, before being marketed fully next year.

Mr. Dunlop said that the design, which accommodates two people, could have other uses, such as for disaster relief and housing for the London Olympics.

For music events, the cardboard houses will be ordered online and put up at the sites by the Myhab team before the festival-goers arrive and removed by the company afterwards. They can be personalized and the company will offer reductions on the expense if people agree to sell exterior (外部的) advertising space.

The biggest festivals attract tens of thousands of participants, with Glastonbury having some 150,000 each year. Altogether there are around 100 annual music festivals where people camp in the UK. The events are becoming increasingly environmentally conscious.

1.“Eco-friendly tents” in paragraph 1 refer to tents _______.

A. economically desirable      B. favorable to the environment

C. for holding music performances               D. designed for disaster relief

2.Mr. Dunlop established his business ______.

A. independently with an interest-free loan from Mint

B. with the approval of the City’s administration

C. in partnership with a finance group

D. with the help of a Japanese architect

3.It is implied in the passage that _______.

A. the weather in the UK is changeable in summer

B. most performances at British festivals are given in the open air

C. the cardboard tents produced by Mr. Dunlop can be user-tailored

D. cardboard tents can be easily put up and removed by users.

4.The passage is mainly concerned with ______.

A. an attempt at developing recyclable tents

B. some efforts at making full use of cardboards
