Directions: Read the following passage. Summarize in no more than 60 words the main idea of the passage and how it is illustrated. Use your own words as far as possible.

Since the dawn of civilization, crop diversity has always been holding an important position as the foundation of agriculture. Food plants have been domesticated, selected, exchanged, and improved by farmers in traditional ways, within traditional production systems. This process has been hugely accelerated and focused by scientific crop improvement, leading to the steady rise in yields since the 1960s. Half of the increase in food production globally can be attributed to genetic improvement.

But experts say the number of crops has decreased sharply during the past century. One of the world’s largest seed conservation projects has predicted further losses. The Millennium Seed Bank Partnership is warning that up to one hundred thousand plant species could permanently disappear. The rich collection of genes that decide their qualities would disappear with them.

Many experts blame climate change for damaging plant life. Rising temperatures, changing seasonal patterns and increasing frequency of extreme weather events are the invisible hand behind the great reduction. Others say human activities and poorly planned, overly heavy use of land also are responsible. The United Nations Food and Agriculture Organization says modern business farming is responsible for loss of farmers’ traditional crop varieties. Though the use of modern commercial farming methods saved millions of people from starvation, some traditional crops were lost during the process.

More recently, the UN Sustainable Development Goals have called for global efforts to highlight the protection and revival of crop diversity as an important means to ensure that crop diversity is conserved and made available for food and nutritional security to feed the increasing population of our planet. On top of the agenda is to maintain the genetic diversity of seeds and cultivated plants through soundly managed and diversified seed and plant banks at the national, regional and international levels. Equally important, more government funds be channeled into rural infrastructure, agricultural research and extension services, technology development and plant gene banks in order to enhance agricultural productive capacity in less developed countries.

Climate change is changing the flavor of French wine

Records going back 700 years show that Burgundy’s wine grapes have been feeling the heat of the past three decades.

The summer of 1540 was burning hot in the vine-covered hills of Burgundy, France—so hot as to be “almost unbearable,” according to one written account from the time. 1. In the Alps, glaciers melted, their snouts retreating up steep-sided valleys. Fires burned from France to Poland. And in the wine country of central France, the grapes withered to raisins (葡萄干) on the vine, so sugary the wine made from them was syrupy and extra-alcoholic.

2. the look of the vines before they bud; the look of the vines as they mature over long seasons; and the fat, sugary, fragrant curve of the grapes when they’re ready to be made into wine. Normally, winemakers harvested grapes at the very end of September or early October. But that year, they had to rush to get overripe grapes off the vine weeks earlier than usual.

Now, a nearly 700-year-long record of harvest shows that early harvest dates like the one from 1540 are now par for the course, thanks to climate change. 3. “We can clearly see the reaction of the grapes to the rise in temperature,” says Thomas Labbé, an historian at the University of Burgundy. “We can predict, using modeling, the harvest will occur around about the 15th of August, in the core of summer.”

4. Already, as temperatures worldwide have warmed, the alcohol content of wines has bumped up from about 12 percent in the 1970s to about 14 percent today, though that number varies from region to region. Part of that, though, is winemaker preference, part of it is because grapes are maturing faster in the heat. The more sugar they accumulate, the more of it is converted to alcohol during the winemaking process.

A. Though the kind of heat hasn’t settled into Burgundy yet, it’s probably coming.

B. Winemakers have kept careful track of the harvest dates for centuries.

C. That will almost certainly affect the way wines taste and feel, and how strong they are.

D. In fact, it was hot all across Europe that year.

E. The subtle feel resulting from more alcoholic wine is not favored.

F. Winemakers know the growth stages intimately.

    There’s more fresh water hidden below Earth’s surface in underground aquifers (含水层) than any other source besides the ice sheets. That groundwater earns an unshakably important place for rivers worldwide, keeping them running even when droughts bring their waters low.

But in recent decades humans have pumped trillions of gallons out of those underground reservoirs. In a new research, water experts and scientists are taking a global look at where groundwater is already being extracted at such a rate that it has caused water levels to drop so much in rivers and streams that they will slip into the ecological danger zone.

Much of that water is being removed much faster than it can be refilled. That has enormous potential consequences for people and crops in areas that don’t get enough rain. But far before those impacts emerge, the effects will fiercely hit rivers, streams, and the habitats around them. Hundreds of rivers and streams around the world would become so water-stressed that the entire ecological system would hit a danger point, says Inge de Graaf, the lead author of the research. “We can really consider this ecological effect like a ticking time bomb,” she says. “If we pump the groundwater now, we don’t see the impacts until like 10 years further or even longer.”

But the severity of the impacts might still be underestimated. As a baseline, they used the global water demand in 2010 and spun their climate model forward to predict how stresses on groundwater systems might develop. But as populations swell and the demand for food rises, those stresses could skyrocket for reasons other than climate change, speeding along the extraction from underground water sources.

The effects of over-pumping groundwater take years, if not decades, to become visible. Changes in rain have immediate, obvious effects on river flow. When it pours, rivers often rage. But groundwater is hidden and changes don’t always manifest in the place where the pumping occurs and are programmed to “wait for the perfect moment”. That makes aquifer management issues extra challenging. In the meantime, rivers and streams are the signal that says we’re using water in an unsustainable fashion, we need to take a hard look at what we’re doing.”.
