【题目】 Schools are now running remote (远程) lessons for more than 90 per cent of NSW students because of COVID-19 (冠状病毒) crisis, a situation likely to l1 for months. The NSW Department of Education says the lessons are designed to be done without parents' too much caring.

But parents are still under the pressure of trying to support their students' learning, saying they have been given an i2 task.

One parent said she spent the week working at her job, then the weekend catching up on all the work her children had missed, doing housework at night. Another single mother wakes at 3 a.m. to do her paid work so she can supervise (监督) her children d3 the day.

"Do they understand that parents are fighting for our lives, our jobs, and our companies as well?" another parent said. "I' m a working mum. If I don't do my job, I may l4 it. I know things had to be done in a hurry. But parents have been thrown in the deep end.

Yvette McDonald, from the inner west, has two young children at a public primary school, which issues (发布) written lessons and requires typed, o5 communication, such as being present for roll call (点名) at the b6 and the end of each day. She has asked the NSW Department of Education to relax those rules, saying they were difficult to carry out.

"Parents are already at breaking point and we haven't even gone into formal lockdown, "she said. "Many of us are managing crisis at work, but then on top of that we're schooling our children as well. We feel as though we're failing, but we're not failing-we've been a7 to do very difficult things. We want to know what's essential and what's not."

【题目】 Inspiration can be a strange thing. You never know when it might hit. And sometimes, it can come from the most unexpected places.

I recently read about an author(作家) named Okorafor. When she was in college, she had a serious spine disorder(脊椎病). Okorafor was told that a simple operation(手术) could fix it.

But when she woke up from her operation, she found that she couldn't move her legs and was in great pain.

Okorafor got well later. But before she did, she saw strange things in her hospital room.

She imagined her pain as a beast(野兽)that hunted her from the shadows. But she also imagined a woman-a woman who could fly, in fact. This magical woman inspired her and helped her forget her pain. "I felt greater than myself. I felt myself become greater," she wrote in her book Broken Places & Outer Spaces: Finding Creativity in the Unexpected.

We never know where we might find the inspiration to create. As a musician, most of my inspiration comes from other people's music. But I also find ideas in other places. Books, movies and even just moments in everyday life can lead to new creations.

For example, I recently watched the film Blade Runner. I've seen it plenty of times before; it's one of my favorite movies. But this time, for some reason, I saw it differently. I decided to make music that could create the same feeling as the film. It's not done yet, but the movie's setting and characters impacted the music I'm working on now heavily.

Anything can inspire us. You just have to be ready to catch inspiration when it hits.

【题目】 Want to know what we can do to help make our city a better place to live in? Why not take part in “Clean & Green weekend”? Join us, and you can make new friends and help protect the environment at the same time.

Park Life

Do you like hanging out in the park with your friends? If so,why not take the chance to come with us and tidy up the park as you go? To add some fun, there is a gift for the person who collects the most rubbish! Meet us at the south entrance to Taohe Park at 9 a.m. next Saturday if you want to join in.

The Air You Breathe(呼吸)

A great way to make the air we breathe cleaner is by planting lots of trees! It is a fact that trees slowly filter(过滤)a lot of pollutants from the air. So come and help us plant some new ones in Fenhe Park at 2 p.m. next Sunday.

War on Graffiti(涂鸦)

Some people think graffiti is cool. Well, it is not! The best way to stop buildings from becoming totally covered in ugly graffiti is to get rid of it as soon as possible.

【题目】Bacterial Quorum Sensing

Bacteria(细菌)play an important role in our lives. They can keep us alive as well as make us sick. It wasn’t until fairly recently that we learned bacteria can communicate with one another.

In the 1960s, researchers found that a kind of bacteria called Vibrio fischeri(费氏弧菌) produced no light when they were alone, but that they exhibited great amount of light as the bacterial population grew to a certain number. How did this happen? How can Vibrio fischeri tell the difference between times when they’re alone and times when they’re in a community, and then all do something together?

Researchers found they talk to each other with a chemical language—signal molecules(信号分子). Vibrio fischeri makes signal molecules, and it also has a receptor on its surface that fits like a lock and key with a signal molecule. As the bacteria increase, more and more signal molecules are sent into the environment. When signal molecules increase to a certain amount, they lock down into those receptors and information comes into the bacteria, which tells them how many neighbors there are. As soon as they realize the population has hit the certain number, all of the bacteria behave as a group, making light together. In the past ten years, researchers have found all bacteria have systems like this: they make and recognize chemical words, determine(判断)the size of the community, and carry out tasks that would be unsuccessful if a single one were to act alone. This process is called quorum sensing.

Most of the time, bacteria live with thousands of other species (种类)of bacteria. There has to be a language of interspecies communication. In fact, bacteria have another kind of signal molecule, which is the common language used by all species. Moreover, this kind of molecule has its own receptor. In this way, bacteria are able to count different populations, and then they decide what task to carry out depending on which species has the greatest population.

Knowing how bacteria communicate could influence how we fight disease. What if bacteria can’t talk or hear? They won’t recognize when there are enough bacteria and when to exhibit the group behavior to make us sick. Researchers are developing a method—to make molecules that look like the real ones and then they lock into the receptors to jam recognition of the real situation.

On the other hand, researchers also improve the conversation of the beneficial bacteria, so they can do things that we want them to do better than they would do on their own.

1According to the passage, what can we learn about quorum sensing?

A.Quorum sensing may happen when there is only one Vibrio fischeri.

B.Signal molecules are kept away from receptors during quorum sensing.

C.Most bacteria have similar systems to make light during quorum sensing.

D.Bacteria carry out a group task when their population hit a certain number.

2What can we learn from the passage?

A.The more species there are, the more group actions bacteria will take.

B.In different environments, bacteria have different interspecies languages.

C.Beneficial bacteria communicate better by themselves than harmful ones.

D.To fight disease, researchers try to turn off the communication between harmful bacteria.

3The passage is mainly about ________.

A.why bacterial population growsB.how bacteria communicate with each other

C.which bacteria help fight diseaseD.what scientists do to find quorum sensing

【题目】 How far can scientists let their curiosity go? The Ig Nobel Prize, a spoof (滑稽模仿) of the prestigious (权威的) Nobel Prize, exists to award unusual or unimportant achievements in scientific research.

The awards are given every year to the 10 strangest research projects of the year. It is to "honor achievements that first make people laugh, and then make them think"

On September 12, the 2019 winners of the Ig Nobel Prize were announced. Here are three of them.

Medicine Prize: Pizza

It's one of the world's most popular foods. but what if we told you that a pizza can protect you against illness and death? According to the Ig Nobel Medicine Prize winner, eating more pizzas can lower the risk of cancer and heart disease---if your pizza is filled with fruits and veggies. These provide flavonoids (类黄酮) to fight against certain diseases. So, if you're a pizza enthusiast, you now have one more reason to love it!

Economics Prize: Dirty Money

As one of the most frequently passed items on the planet, paper money is known to pick up all kinks of bacteria (细菌). Which country's money is the dirtiest? To find the answer, an international team of scientist compared seven countries' paper money. They found that the notes including more polymer (聚合物) specifically the Romanian Leu carry more drug-resistant pathogens (病原体). Perhaps this will make cashless payments popular.

Biology Prize: Cockroach(蟑螂)

Cockroaches are well known for their survival abilities, but few people know they can sense magnetic (磁性的) fields. More surprisingly, an international team found that dead cockroaches have more magnetic properties (特性) than live ones. That's because magnetic properties drop when the temperature gets higher.

So if you can stand cockroaches, they may be good magnetic sensors.

1According to the survey, which country's paper money is the dirtiest?

A.RomanB. LebanonC. RussianD.Romanian

2What kind of cockroach may have more magnetic properties?

A.A dead one near the stove.B.A live one near the stove.

C.A dead one near the fridge.D.A live one on the ground.

3Which of the following statements is True according to the passage?

A.The Ig Nobel Prize is a kind of prestigious Nobel Prize.

B.If a person has cancer and heart disease, he shouldn't eat too many pizzas.

C.Because paper money is useless, this makes cashless payments more popular.

D.Because cockroaches have magnetic properties, people may apply this feature to sensors.
