A
Scientists visiting tiny Henderson Island in the South Pacific recently made an alarming discovery．Although it is one of the most remote places on the Earth and previously untouched by humans, the island was covered in plastic waste．They calculated there were 38 million pieces of plastic, weighing almost 18 tons, with thousands of new pieces washing up each day．“No country has a free pass — we found plastic from everywhere，” said one scientist．“We all have a responsibility, and we have to sit up and pay attention．This is not an issue to ignore．We need to do something now to protect the sea．”
Plastic waste in the sea has long been known about, but only now are we discovering the true extent of the problem．Plastic takes hundreds of years to decompose, so all the plastic ever produced still exists somewhere．Around 95% of plastics made are not recycled, and large amounts enter the sea．Currents collect this waste in large circular systems called “gyres”．One of the largest is in the Pacific Ocean, an area now known as the “Great Pacific Garbage Patch”．
The problem gets worse as plastic breaks down into very small pieces, or “micro plastic”．This is eaten by fish and leads to massive species loss．Humans also eat these fish, and micro plastic has even been found in tap water around the world．The problem has spread too far to ignore．The plastic on Henderson Island accounts for just 2 seconds' worth of global annual plastic production．That production will more than triple by 2050．Then there will be the same weight of plastic in the sea as fish．
However, there are some young minds working to clean up and protect the sea for future generations．While diving in Greece, young Boyan Slat noticed there was more plastic waste than fish．He decided right then to dedicate his life to solving this problem．Previously the problem was considered too big to solve; collecting the plastic with boats and nets would be expensive, would harm sea life, and would take thousands of years! But, Boyan thought, why move through the sea when the sea can move through you To work with the currents and gyres would help collect the waste．So he started the Ocean Cleanup Project, which places very long floating barriers in the Pacific．Currents then concentrate the waste naturally so it can be collected and recycled．He hopes to reduce the patch by 50% in just five years．
“Many problems today are side effects of things people didn't think about in the past，” he says．Sea plastic is a symbol of the negative effects of our lifestyle and technology．Our aim should be to create a new lifestyle for this century．Protecting the sea from plastic is a good place to start．

(2023·秦皇岛模拟)Marathon runner Gerima Mustafa of Uganda walked some 664 kilometres across East Africa earlier this year to call attention to threats to the shea (乳木果) nut tree, a source of food, medical products and income for the many living from West Africa to Somalia．
Now research scientists studying the shea tree in Burkina Faso have found that it is the natural ecosystem that is getting degraded in this region that might do harm to the shea, which is often targeted by charcoal (木炭) traders who kill and sell the trees for far less than the long-term worth of their benefits．The habitats are lost to ever-increasing agricultural shifts too, with a clear overall link to the impacts of human activity．
Scientist Aoife Delaney of the UK, along with researchers of Burkina Faso and British ecologists, studied 10 different parkland locations in Burkina Faso where the trees are planted．They say the tree — able to produce nuts for 200 years — relies on pollinators (传粉者) that thrive when other trees and shrub (灌木) species around it create a habitat to support the pollinators, especially bees．
“Consequently, shea productions are likely to benefit from the preservation of a range of different tree and shrub species in parklands，” Delaney and the research team said．Their work was recently published in the Journal of Applied Ecology．
The authors recommend maintaining a range of native woody species throughout their lifespans, and planting new ones into farmland when cleared．The idea is to be intentional and active about protecting the trees．
“Only separate parts of semi-natural habitat in the surrounding landscape may not be sufficient to provide the necessary pollination services，” they concluded．“In a region that is subject to nutritional poverty and where the fund required to supply local foods is lacking for most families, maintaining natural ecosystem services that support food provision must be a priority．”
【语篇解读】本文是一篇说明文。文章介绍了乳木果树面临的威胁及对其采取的保护措施。
5．Why is Gerima Mustafa mentioned in the first paragraph
A．To describe a marathon runner's experience．
B．To suggest the popularity of Gerima Mustafa．
C．To introduce the importance of shea nut trees．
D．To explain an approach to protecting the wildlife．

Ⅱ．语法填空
Planting trees is a great way to reduce carbon emissions, but protecting our oceans and coastal ecosystems can do the same
“Blue carbon” refers to organic carbon which 1．is stored (store) by the oceans and coastal ecosystems．Mangroves, tidal marshes and seagrasses are the three main coastal ecosystems that can store large 2．quantities (quantity) of blue carbon．They play a major role in reducing carbon dioxide in the air．
3．Compared (compare) with ecosystems on the land, coastal ecosystems can store carbon 4．constantly (constant) in the long term．When plants on the coast die, the organic deposits that they become will slowly disappear thanks to the flowing seawater above, 5．which means the carbon will not escape easily but remain stored for hundreds and thousands of years．
China is one of the few blessed 6．with all three coastal ecosystems．Tidal marshes are the largest coastal ecosystem in China, 7．occupying (occupy) an area of 5，448 square kilometres．In comparison, mangroves have a 8．smaller (small) size．According to the latest data, the total area of China's mangrove forests in 2020 9．was (be) 289 square kilometres, and over 70 square kilometres of mangroves are newly planted and restored now．
By protecting and restoring these coastal ecosystems, we can avoid enormous amounts of stored blue carbon going back into 10．the atmosphere, and safeguard wildlife living in these ecosystems．
