【推荐2】Bats quickly eat the insects that bite us and ruin our crops. They pollinate (授粉) flowers and they replant forests by spreading seeds around. But as agriculture overtakes rain forests and jungles, humans have come into conflict with one bat species: the common vampire bat (吸血蝙蝠).

Well, vampire bats are ugly little animals. They’ve got these wrinkly noses that have infrared (红外线的) heat sensors so they can detect warm blood flowing beneath the skin. They’ve got ears that can pick up the sound of low frequencies. That’s the sound of big animals breathing. And they have super sharp teeth. So when you’re bitten by one of these bats, you don’t even feel it. They also have amazing movement skills. They can fly, but they can also run with their wings,

And vampire bats mainly interact with humans who are raising livestock. They’ll drink the blood of cows and pigs and chickens. You can find newborn cows with bites from vampire bats, chicken coops that are covered in drips of blood. Children will regularly wake up with vampire bat bites on their feet. Actually, the bites aren’t that big of a health problem. The main problem is that very rarely these bats are sick with rabies (狂犬病). And they can spread this fatal disease to cattle and people.

Gerry, a scientist, does experiments where he keeps one of the bats away from food for a night. And that’s something that actually happens in the wild all the time. The bat will go out and it can’t find anything to eat. And if that happens two nights in a row, the bat could actually starve to death. But what happens is that another bat will come in and they’ll rescue that hungry bat. They’ll let out a little blood to feed it. And this behavior is seen between mothers and their children and between siblings. But surprisingly, it’s also seen between bats that aren’t related at all.

【推荐1】Japan’s youth are losing interest in science and as a result, threatening the nation’s industrial progress. According to Japan Science and Technology Agency, young Japanese are surrounded by high-tech devices(设备), but are not interested in how they work.
Japanese businesses have succeeded partly because they’ve a great many engineers. A drop in interest could lead to a decline(减少) in their numbers and quality. "In the past, the young had a big interest in science and technology," said Hirano, director of the agency’s policy department.
There are two main reasons for the problem. The first is known as "black box syndrome" of modern technology.
Electronic devices depend on tiny silicon chips（芯片）, which can only be made in big factories, whose workings can’t be seen by the eyes. The devices, unlike machines of the past driven by gears and wheels, are simply boxes.
Young Japanese, brought up on video games and at home with computers, enjoy using modern technology, but this is a passive interest and different from the interest in how things work. "You need an active interest to get interested in science. This is declining in the young," said Hirano.
About two-thirds of Japanese in their 20s use PCs, twice the number of those in their 50s. But only 40% of those in their 20s say they are interested in news about science and technology, compared to 60% of the 50 to 60 year olds.
"Another reason for it is that life in modern Japan is too comfortable," he said. "A wealthy society reduces people’s desire to modernize and develop their country. To a degree, you can’t avoid this when the fruits of science and technology are fully developed." Similarly, science in Europe and the US has also suffered a lack of interest.
1. Japanese youth’s interest in science is dropping probably because ________.

A．scientists don’t make much money in Japan

B．there are too many scientists in Japan already

C．they’re not interested in how high-tech devices work

D．science is more difficult for young people to learn

2. The underlined word "their" (in Para. 2) refers to ________.

A．Japanese engineers’

B．Japanese businesses’

C．Japan’s young people’s

D．high-tech devices’

3. Why does science meet the same problem in Japan, the US and Europe?

A．People believe they don’t need to develop their science any more.

B．People are satisfied with the comfortable life high-tech devices bring to them.

C．People think high-tech devices destroy the environment.

D．People don’t want to live the modernized life.

4. Which of the following is NOT true according to the passage?

A．Older people are probably more interested in science in Japan.

B．About one-third of Japanese people in their 50s use computers.

C．Japan’s youth live too comfortably to take interest in science.

D．Electronic devices are made of parts that can not be seen at all.

【推荐2】The Hunan Satellite TV(HNTV) show “Where are we going, Dad?” is a big hit. Many famous stars brought their children to a strange village alone, and they had to spend 72 hours with their children there. The program fully showed us a modern version of the “how to be a good father”. As the young parents today are too busy to take care of their children, this new form of“Lost on the way”played by nanny daddy and cute kids triggered（触发）a lot of people’s emotional resonance（共鸣）. Both the kids and their parents will find that their hearts are being drawn closer. But this kind of feeling has just proved that there is a big spiritual barrier between the modern parents and children.
The TV shows like “Children are hard to support!”, “Where are we going, Dad?”, “hot mom” and “cute kids” are becoming more and more popular. All of these show the new parents’ confusion in children’s education and the appeal for the balance between career and family.
In real life, on the one hand the young parents feel helpless because they are too busy to accompany their children under the pressures of work and life; on the other hand they continue to do so. The data collected by HNTV show that nearly two-thirds of their audience are female, among whom 36% are aged from 25 to 34. We can imagine such a scene that one evening a young mother is watching the show with her young children, while her husband is still at work or trapped in socializing, or maybe is just playing computer games in the bedroom. The story of a child without the company of father is still going on. In fact, it is sometimes the same to mothers. In a modern family, it is often the old who take the responsibility of raising a child. The participation of mother in the children’s education is also very low.
It is just this kind of confusion where the parents have gone in the modern family education, and where the parents will guide their children to go that“Where are we going, Dad?”shows us. If a child wants to grow up healthily and safely into a modern citizen with independent personality and free spirit, it is very important for him or her to follow the parents who serve as their first teacher. Maybe this is the real reason why such kind of TV programs could get hot. The truth is that children will go where their parents go; and society will go where the children go.
1. Which of the following can be inferred in the passage?

A．Parents shouldn’t entirely leave the education of children to the old.

B．36% of the audience of the program are female aged from 25-34.

C．The program shows us the confusion where the parents and children will go to play.

D．In a modern family it is often mothers who are responsible for raising a child.

A．play computer games with their children

B．break down the barrier between children and teachers

C．balance well between family and career

D．keep their children at home to avoid socializing

4. What attitude towards modern family education does the author express in the second paragraph?

A．Optimistic.

【推荐3】Pushing Back School Starting Times

It’s January. The outdoor temperature has fallen below 5℃ in the morning. Have you ever complained that you still have to get up at 6 a.m. and arrive at school before 7 a.m.? Do you wish you could have a long nice lie-in?

You are not alone if your answer is “Yes!” In the United States, many high school students are unhappy with their school starting times, too. According to a survey in 2018, only in two states-Alaska and Connecticut-do schools start after 8:30 a.m.

That may soon change.    1     The law sets a limit on starting times of half-past eight for high-schoolers and eight o’clock middle schoolers, which will go into effect on July 1, 2022, and applies to all public schools in California.

There are plenty of reasons to think the law will benefit students. According to a number of medical organizations, circadian rhythms—the 24-hour biological cycles that govern our waking and sleeping, among other things-keep changing throughout our lives. During our teenage years, we are more alert in the afternoon and require more sleep in the morning. A combination of poor sleep habits and early school starting times means most young people aren’t getting enough sleep.

    2     A research review by the US Centers for Disease Control and Prevention(C.D.C.)finds that later school starting times can lead to less falling asleep in class. The change can also help improve students’ attendance and grades. The C.D.C. recommends that middle and high schools start at 8:30 a.m. or later to ensure that students arrive awake and ready to learn.

However, many parents are strongly opposed to such changes. Those who cannot start work later say they won’t be able to drop their children off at school before they go to work. They also fear that later starting times will mean later ending times, resulting in fewer opportunities for their children to take part in after-school activities, hold part-time jobs and care for younger siblings.    3    

Supporters, however, argue that it is appropriate for the state to set a minimum health-and-welfare standard, as it does in many other areas.    4     “There really is no significant reason not to do this,” he says. “I only see an overwhelming resistance to the change from adults-something many teenagers will be familiar with.”

A．Sleep deprivation is associated with problems in attention, behavior and learning.

B．Gavin Newsom, California’s governor, hopes students will benefit from their extra time in bed guaranteed by the law.

C．Anthony Portantino, the California senator who introduced the law, believes evidence of the change’s benefits will soon win over opponents.

D．Some politicians in California say Mr Newsom’s decision about when schools start should be left to school districts.

E．Last October, Gavin Newsom, California’s governor, signed a law that cuts 2.7 million of the state’s schoolchildren some loose.

F．Many US states have responded to the scientific evidence and begun to move starting times back.
