Animal moms are great moms. You might be surprised at some of these moms.
Octopuses(章鱼)
The octopus mother lays(下蛋) about 50,000 eggs. For about 300 days, she stays with the eggs, cleans them and protects them. She does not leave to feed. However, this animal mom dies as soon as the eggs are hatched(孵化).
Crocodiles (鳄鱼)
A crocodile mother puts a lot of time and effort(努力) into raising her babies.
She starts by building a nest(巢)which she guards for over two months! When the eggs are ready to hatch, the young crocs call out to their mother, who digs them out and helps them hatch. She then carries them in her mouth down to the water, where she will guard them for several more weeks or months until thy learn to hunt on their own.
Bats(蝠)
Bats become moms by hanging head up in a cave, giving birth. Catching the youngsters before it can fall to the ground below, she puts it in a pouch (育儿袋) .Bat moms may carry babies with them when feeding for the first few days. As the little bats get bigger and heavier, moms help them hang on the wall of their caves and return to feed them. It continues for about three weeks, until the babies are grown up and able to fly on their own.
Koalas(考拉)
The animal mom gives birth after pregnancy(怀孕期)of only 35 days. The hairless baby climbs into its mother’s pouch and lives there for another five months. When the little koala is between five and eight months old, it leaves the pouch for short periods of time but returns for safety. Once it is too big to return to the pouch, it will climb onto its mother’s back and ride there until it is about 12 moths old.Which animal moms die when their babies are born?

I was in the middle of the Amazon （亚马逊） with my wife，who was there as a medical researcher．We flew on a small plane to a faraway village．We did not speak the local language，did not know the customs，and more often than not，did not entirely recognize the food．We could not have felt more foreign．
We were raised on books and computers，highways and cell phones，but now we were living in a village without running water or electricity．It was easy for us to go to sleep at the end of the day feeling a little misunderstood．
Then one perfect Amazonian evening，with monkeys calling from beyond the village green，we played soccer．I am not good at soccer，but that evening it was wonderful．Everyone knew the rules．We all spoke the same language of passes and shots．We understood one another perfectly．As darkness came over the field and the match ended，the goal keeper，Juan，walked over to me and said in a matter﹣of﹣fact way，"In your home，do you have a moon too？" I was surprised．
After I explained to Juan that yes，we did have a moon and yes，it was very similar to his，I felt a sort of awe（敬畏） at the possibilities that existed in his world．In Juan's world，each village could have its own moon．In Juan's world，the unknown and undiscovered was vast and marvelous．Anything was possible．
In our society，we know that Earth has only one moon．We have looked at our planet from every angle and found all of the wildest things left to find．I can，from my computer at home，pull up satellite images of Juan's village．There are no more continents and no more moons to search for，little left to discover．At least it seems that way．
Yet，as I thought about Juan's question，I was not sure how much more we could really rule out．I am，in part，an ant biologist，so my thoughts turned to what we know about insect life and I knew that much in the world of insects remains unknown．How much，though？ How ignorant （无知的） are we？The question of what we know and do not know constantly bothered me．
I began collecting newspaper articles about new species，new monkey，new spider…，and on and on they appear．My drawer quickly filled．I began a second drawer for more general discoveries：new cave system discovered with dozens of nameless species，four hundred species of bacteria found in the human stomach．The second drawer began to fill and as it did，I wondered whether there were bigger discoveries out there，not just species，but life that depends on things thought to be useless，life even without DNA．I started a third drawer for these big discoveries．It fills more slowly，but all the same，it fills．
In looking into the stories of biological discovery，I also began to find something else，a collection of scientists，usually brilliant，occasionally half﹣mad，who made the discoveries．Those scientists very often see the same things that other scientists see，but they pay more attention to them，and they focus on them to the point of exhaustion（穷尽），and at the risk of the ridicule of their peers．In looking for the stories of discovery，I found the stories of these people and how their lives changed our view of the world．
We are repeatedly willing to imagine we have found most of what is left to discover．We used to think that insects were the smallest organisms （生物），and that nothing lived deeper than six hundred meters．Yet，when something new turns up，more often than not，we do not even know its name．

For those who can stomach it，working out before breakfast may be more beneficial for health than eating first，according to a study of meal timing and physical activity．
Athletes and scientists have long known that meal timing affects performance．However，far less has been known about how meal timing and exercise might affect general health．
To find out，British scientists conducted a study．They first found 10 overweight and inactive but otherwise healthy young men，whose lifestyles are，for better and worse，representative of those of most of us．They tested the men's fitness and resting metabolic （新陈代谢的） rates and took samples （样品） of their blood and fat tissue．
Then，on two separate morning visits to the scientists' lab，each man walked for an hour at an average speed that，in theory，should allow his body to rely mainly on fat for fuel． Before one of these workouts，the men skipped breakfast， meaning that they exercised on a completely empty stomach after a long overnight fast（禁食）．On the other occasion，they ate a rich morning meal about two hours before they started walking．
Just before and an hour after each workout，the scientists took additional samples of the men's blood and fat tissue．
Then they compared the samples．There were considerable differences．Most obviously，the men displayed lower blood sugar levels at the start of their workouts when they had skipped breakfast than when they had eaten．As a result，they burned more fat during walks on an empty stomach than when they had eaten first．On the other hand，they burned slightly more calories（卡路里）， on average，during the workout after breakfast than after fasting．
But it was the effects deep within the fat cells that may have been the most significant，the researchers found Multiple genes behaved differently，depending on whether someone had eaten or not before walking．Many of these genes produce proteins （蛋白质） that can improve blood sugar regulation and insulin（胰岛素） levels throughout the body and so are associated with improved metabolic health．These genes were much more active when the men had fasted before exercise than when they had breakfasted．
The implication of these results is that to gain the greatest health benefits from exercise，it may be wise to skip eating first．

| A． |
digest the meal easily |
| B． |
manage without breakfast |
| C． |
decide wisely what to eat |
| D． |

Their lifestyles were typical of ordinary people． |
| B． |
Their lack of exercise led to overweight． |
| C． |
They could walk at an average speed． |
| D． |
They had slow metabolic rates． |
（3）What happened to those who ate breakfast before exercise？
| A． |
They successfully lost weight． |
| B． |
They consumed a bit more calories． |
| C． |
They burned more fat on average． |
| D． |
They displayed higher insulin levels． |
（4）What could be learned from the research？
| A． |
A workout after breakfast improves gene performances． |
| B． |
Too much workout often slows metabolic rates． |
| C． |
Lifestyle is not as important as morning exercise． |
| D． |
Physical exercise before breakfast is better for health． |
Sometimes it's hard to let go．For many British people，that can apply to institutions and objects that represent their country's past﹣age﹣old castles，splendid homes…and red phone boxes．
Beaten first by the march of technology and lately by the terrible weather in junkyards（废品场），the phone boxes representative of an age are now making something of a comeback．Adapted in imaginative ways，many have reappeared on city streets and village greens housing tiny cafes，cellphone repair shops or even defibrillator machines（除颤器）．
The original iron boxes with the round roofs first appeared in 1926．They were designed by Giles Gilbert Scott，the architect of the Battersea Power Station in London．After becoming an important part of many British streets，the phone boxes began disappearing in the 1980s，with the rise of the mobile phone sending most of them away to the junkyards．
About that time，Tony Inglis' engineering and transport company got the job to remove phone boxes from the streets and sell them out．But Inglis ended up buying hundreds of them himself，with the idea of repairing and selling them．He said that he had heard the calls to preserve the boxes and had seen how some of them were listed as historic buildings．
As Inglis and，later other businessmen，got to work，repurposed phone boxes began reappearing in cities and villages as people found new uses for them．Today，they are once again a familiar sight，playing roles that are often just as important for the community as their original purpose．
In rural areas，where ambulances can take a relatively long time to arrive，the phone boxes have taken on a lifesaving role．Local organizations can adopt them for l pound，and install defibrillators to help in emergencies．
Others also looked at the phone boxes and saw business opportunities．LoveFone，a company that advocates repairing cellphones rather than abandoning them，opened a mini workshop in a London phone box in 2016．
The tiny shops made economic sense，according to Robert Kerr，a founder of LoveFone．He said that one of the boxes generated around ﹩13，500 in revenue a month and cost only about ﹩400 to rent．
Inglis said phone boxes called to mind an age when things were built to last．"I like what they are to people，and I enjoy bringing things back，" he said．

| A． |
to form a beautiful sight of the city |
| B． |

（2）Why did the phone boxes begin to go out of service in the 1980s？
| A． |
They were not well﹣designed． |
| B． |
They provided bad services． |
| C． |
They had too short a history． |
| D． |
They lost to new technologies． |
（3）The phone boxes are becoming popular mainly because of ．
| A． |
