1 . The government's top Great Barrier Reef scientist says a third mass coral bleaching (珊瑚白化) event in five years is a clear signal that the marine wonder is “calling for urgent help on climate change. Corals can recover from mild bleaching, but severe bleaching can kill corals.

Prof Terry Hughes, director of the Centre of Excellence for Coral Reef Studies at James Cook University, surveyed 1,036 reefs from a plane over nine days in late March.

The marine park authority also had an observer on the flights. The survey has released   maps showing that serious levels of bleaching occurred in 2020 in all three sections of the   reef northern, central and southern. Some 25% of the reefs were seriously bleached-meaning that more than 60% of the corals on each reef had bleached.

The Great Barrier Reel has experienced five mass bleaching events-1998. 2002,2016, 2017 and 2020 -all caused by rising ocean temperatures driven by global heating. Hughes said there probably would not be the same level of coral death in the north and central regions in 2020 as in previous years, but this was partly because previous bleaching outbreaks had kill off the less heat -tolerant species The 2020 bleaching was second only to 2016 for severity(严重性), Hughes said.

Dr. David Wachenfeld，chief scientist at the Great Barrier Reef Marine Park Authority, told Guardian Australia "My greatest fear is that people will lose hope for the reef. Without hope there's no action. People need to see these bleaching events, They are clear signals that the Great Barrier Reef is alling for urgent help and for us to do everything we can”.

Measures to improve the ability of recovery of the reef include improving water quality, controlling outbreaks of coral-eating starfish, and research and development to improve the heat tolerance of corals. " However, climate change brings a new scale of impact unlike anything we have seen before. Thus, dealing with the climate problem is the basis for everything else to work, ” Wachenfeld said.

2 . More than one million single-use straws (吸管), most of them plastic, are used in the United States each day. They end up in waterways, harm sea animals, and break down into micro-plastics. Quantities of places have passed plastic-straw bans as a way to start handling the global plastic waste problem.

Straw materials: advantages and disadvantages

1. Metal

Made of stainless steel, aluminum, or even titanium, metal straws have become popular. They draw some criticism for having a metallic taste and conducting heat from a hot drink, but they’re strong and can be reused.

2. Paper

Paper drinking straws, which date from the late 1800s, often absorb liquid over time and can leave a taste or fibers in drinks. They’re the most popular throwaway choice in places with plastic-straw bans.

3. Glass

Though glass straws may be more breakable and thus less portable than reusable straws of other materials, they hold up well to washing and reuse. Some straws are made to look artistic, with colors and blown-glass designs.

4. Bamboo

This natural material can be sustainably produced and is a plant-based replacement of plastic straws. Bamboo straws are easily disposed of and turned into fertilizer. They are reusable but can be hard to clean completely and may absorb flavors.

1. What is the major problem with plastic straws?

A．Function.	B．Flavor.
C．Weight.	D．Pollution.

2. Which of the following belongs to single-use straws?

A．Metal straw.	B．Paper straw.
C．Glass straw.	D．Bamboo straw.

3. What is the advantage of the bamboo straw?

A．It can become fertilizer.	B．It is easy to clean.
C．It is portable and bendable.	D．It has different designs.
