[2023·山东省淄博市高三一模] Giant pandas are among the most lovable animals
alive today. Unlike their relatives, such as the polar bear, pandas don't eat meat
but survive on a diet of only bamboo. So why and how have pandas abandoned their
taste for meat to pick up a vegetarian diet?
Pandas today don't eat meat. However, they've kept much of their meateating
adaptations from times past. Their digestive systems have not changed much from their
meateating days. Out of the huge 12.5 kg of bamboo they eat in a single day, only
about 17% of it is digested. To survive, pandas eat large amounts of bamboo while
having a lowmetabolic (新陈代谢的),lazy lifestyle to make up for the poor energy
return.
The giant panda's shift to a vegetarian diet is in line with the inactivation
of a specific geneTaslrl, which provides them with the ability to taste certain
amino acids (氨基酸) abundant in meat. Its inactivation in pandas would lead to their
dietary change.
Pandas have evolved to a great degree to cope with their relatively recent
bambooeating lifestyle. Pandas must seize long and thin pieces of bamboo shoots.
To assist with this,__they have developed a long “fakethumb” (伪拇指). So
giant
pandas have six fingers in each paw which provides better support for them to seize
object such as bamboo in one paw quickly. Researchers have found that the surface
of the panda's tongue is different. While other bears and many meateating animals
have smooth tongues, pandas have evolved tiny projections (凸出物) on the surface
of their tongues that serve to file down food. This is especially useful for pandas
as they remove the outer cover of bamboo.
Time will tell if pandas will adapt and survive, go back to eating meat, or
disappear in the wild. Whatever the future holds, we can be grateful that, for the
time being, we get to share our planet with these adorable animals.

[2023·山东省日照市高考二模] Crossing Phoenix, Arizona, are 180 miles of canals.
In 1867, the city's founding father, Jack Swilling saw the remains of irrigation
(灌溉) channels wandering across the landscape. He realized that, centuries before,
some society had farmed this desert. Soon after, Swilling began clearing the blocked
canals to bring agriculture back to the region.
Three years later, Swilling and other pioneers met to consider names for their
settlement. The top two were Pumpkinville and Stonewall. Luckily, English adventurer
Darrell Duppa proposed a name inspired by the resurrection (复兴) of the canals.
“A great race once lived here and another great race will live here in the future,”
he considered. “I predict that a new city will spring, phoenixlike, from the ruins
and ashes of the old.”
Gary Huckleberry, a researcher, said, “In the southwest, we have some serious
issues to deal with in terms of water. The Colorado River is the main source of water
for the southwest and it's over distributed. We've got population growth and climate
change. How are we going to deal with that? I think there's something to be learned
by looking at past societies who managed water for thousands of years.”
That great society was the Hohokam. Between 100 and 1450 AD, they constructed
1,000 miles of canals. As the Hohokam expanded their network, they constantly
repaired, cleaned and diverted the canals. “It requires cooperation, because all
the users of the water from that canal have to agree not only to construct it, but
also to maintain it,” Henderson, a scientist, said. “Users would have to agree
to certain conditions to keep the entire system going.” The Hohokam committed to
sharing water and put themselves on timetables.
The Hohokam used canal irrigation for 3,000 years. “That, to me, is the
definition of sustainable development,” Huckleberry said. “They learned how to
sustainably farm, to manage water, to not destroy their soils in a way that is worthy
and might give us insight into how we might deal with the current trouble. I think
one of the key lessons is that you don't put all your eggs in one basket.”
5.What is Paragraph 2 mainly about?
A.The reconstruction of canals.
