3 . Do you have any c_______to make about the cause of the disaster?(根据首字母单词拼写)

4 . Sleeping with a dim(昏暗的) light like a television or nightlight is enough to the raise blood sugar and heart rates of healthy people, according to a new study. Light helps our body maintain an internal clock, but artificial light at night can disturb the rest and repair that should happen during the sleep. New research suggests that even when our eyes are closed, a small amount of light can disrupt the way our bodies normally keep our blood sugar within a healthy range.

In the study published in Sciences on Monday, scientists asked 20 participants aged 19 to 36 to spend two nights in their lab. On the first night of sleep, the volunteers slept in a very dark room. For their second night of sleep, half of the group slept with streetlights through a window, and half spent their second night in a dark room.

During the trial, all participants were connected to devices that measured different markers of their sleep quality. They were each connected via a special tube, allowing researchers to collect samples without waking the individual. Researchers also recorded participants’ heart rates and brain waves.

When the volunteers awoke in the morning, the team tested their blood sugar and found that participants that slept in rooms with a dim light spent less time in deep sleep. In addition to having slightly worse blood sugar control, the group exposed to dim light had a higher heart rate on average. By comparison, those that spend two nights in the dark room had little difference in their blood sugar control. “They thought they slept well, but your brain knows that the lights are on,” says Zee, “you should clearly pay attention to the light in your bedroom. If you can’t give up your night light, keep it dim and at floor level.”

Earlier work has linked exposure to light during sleep to an increased risk of obesity (肥胖) in women. Zee recommends, “Make sure that you start dimming your lights at least an hour or two before you go to bed to prepare your environment for sleep.”

1. What does the underlined word “disrupt” in Paragraph 1 probably mean?

A．Bother.	B．Keep.
C．Disagree.	D．Follow.

2. How did the researchers draw a conclusion from the study?

A．By comparing earlier work.

B．By asking and answering questions.

C．By conducting experiments.

D．By analyzing the data from scientific texts.

3. What did the study find if the participants slept in dark rooms?

A．Their heart rate would raise higher.

B．Their blood sugar control wouldn’t change.

C．They would have worse blood sugar control.

D．They would actually sleep more than average.

4. Which of the following is a suitable title for the text?

A．Sleep Well, Eat Well, Good Health

B．The Darker, the Lower Blood Sugar

C．Sleeping With a Dim Light contributes to health

D．Sleeping With a Dim Light Can Raise Health Problems

5 . Smart devices have become an everyday part of our lives. A smart refrigerator can go above and beyond simply keeping our food cool.

A smart refrigerator is any refrigerator that’s equipped with a Wi-Fi connection. It can share information about itself, be a real-time camera that lets users see what’s inside while at the supermarket, or act as a digital command center for the home. Some other things smart fridges are able to do include raising or lowering the temperature at the sound of your voice or with your phone, or helping you track the contents of your fridge so you don’t run into a milk shortage emergency.

Smart fridges can be particularly good at keeping food cool. It’s easier to adjust the temperature if it is higher than it should be because the door is left slightly open. This can make a difference in your energy bills and the quality and lifespan(寿命) of your food.

Many of the smart fridge’s features can also save you time when you’re rushing to get ready in the morning. The people who will benefit most from a smart fridge are probably those who have children who might be using the fridge while parents are at work. It’s another way you can keep an eye on what’s going on at home when you’re not there. However, prices do tend to run higher than traditional fridges.

If you already have a food organizational system that’s working very well for you, and you are cool with the way your fridge is handling your food, then a smart fridge may not be worth it. However, if the smart fridge’s features mentioned above sound like they would make your life easier, then one could be worth the extra money.

1. What can a smart refrigerator do?

A．Order food.

B．Record the contents inside.

C．Deal with emergency.

D．Share information with supermarkets.

2. Which of the following best describes the smart refrigerator?

A．Energy-saving but expensive.

B．Child-friendly but noisy.

C．Time-saving but unsafe.

D．Convenient but power-consuming.

3. What does the author suggest in the last paragraph?

A．Accepting a smart fridge passively.

B．Highly recommending us to own a smart fridge.

C．Thinking reasonably about having a smart fridge.

D．Firmly rejecting the idea of buying a smart fridge.

4. Where does the text most probably come from?

A．A poster.	B．A magazine.
C．A novel.	D．A guide book.

6 . 阅读下面短文，根据所给情节进行续写，使之构成一个完整的故事。

A couple of months before I started high school, my parents gave me the greatest gift any teenage boy could ask for: a cellphone. I lived on that phone all summer with my face buried in its screen. I texted with every friend who was lucky enough to have a texting plan. I ignored my family and my surroundings. Being connected was more important than being present.

So, you can imagine my displeasure when l learned what my dad had planned for our family vacation that year. “This year,” my dad said, “we’ll be doing something special. We’re going camping!” His excitement was met with a disappointed sigh. It wasn’t my dream vacation, but I remained unbothered throughout the packing and planning. My mind was on my phone. I was so buried in the screen, in fact, that the first time I can remember truly looking up was when we drove across a bridge on the way to our campsite.

I stared out the window and saw redwoods towering above us, their branches threatening to pierce (刺破) the blue sky. I saw a roaring river, with slivers of silky black water appearing between crashing white rapids. The air blowing into the car from the open windows was hot and smelled of pine. But none of that mattered to me. The reason I had looked up was for something far more serious. My phone no longer had service.

The last hour of the drive was increasingly tense. My dad announced that he had chosen a campsite that had no cell service, and that my phone would be useless until we returned home. I would be trapped in the forest for four days with no way to contact the outside world! I went through the full cycle of teenage emotions during the first day of the trip. I raged (发怒). I bargained. I begged. I flip-flopped (转变) from a depressive state to anger and back.

I went to bed angrily that night. But when I awoke in the morning, something had changed.

Paragraph 1:

Instead of burying myself in my phone, l focused on something else: my surroundings.

Paragraph 2:

The next four days passed in a flash with many fun activities.

8 . 阅读下面材料，根据其内容和所给段落开头语续写两段，使之构成一篇完整的短文。

When school was over, the day was fading and it started to drizzle(毛毛雨). I stood at the school gate, with a loaded backpack on my shoulders. It was Friday again: a weekend of joy with unlimited sleeping hours and dinner courses specially made to my taste, a weekend at home. I waved goodbye to my friends as they jumped into their fathers’ warm and comfortable cars. Curiously, this gave rise to a disturbing feeling in me. It was not exactly what they called jealousy, but something like dismay(沮丧). I knew all I could expect was an old bike Mom would ride along on, with the badly-oiled chain creaking(嘎吱作响) against the wheel to announce her arrival.

Every Friday when Mom came to pick me up for the weekend, it was a moment full of great expectation and great unease. I always felt my face burning as we rode our way in and out of the numerous cars and saw my friends’ faces sticking out of the car windows. It was like stepping into a ballroom with beautifully dressed ladies and finding yourself in a smelly T-shirt.

To tell you the truth, Mom is quite a headache once in a while. She just looks a homely middle-aged housewife. Being a practitioner of DIY, she knits most of my sweaters, chiefly in old styles. Whenever caught by some curious classmates asking what brand my sweaters are, I’d force a smile and reply in a half joking manner: homemade.

I couldn’t remember when I started to find her such an embarrassment. As a little boy, I relied on her so much. She had been working at home, cooking in the kitchen, knitting by the lamp or riding across town to buy me a book I badly needed. It had always been much fun riding with mom. But just now there seemed to be something standing between us, something that made her so strange to me and me to her.

Today she showed up in a raincoat.

Mom tried to cover me with the back of the raincoat again as a storm set in.

9 . 阅读下面短文，在空白处填入1个适当的单词或括号内单词的正确形式。

More than 500 pieces of relics     1     (discover) at the Sanxingdui Ruins site last year. The relics include golden masks, jade and ivory artifacts and bronze wares     2     were exquisitely (精美地) built and     3     (unique) shaped, said the Sichuan Provincial Cultural Heritage Administration on Sept. 9, 2021. The new discoveries bring the total number of items unearthed at Sanxingdui     4     nearly 2,000 after the excavation of No. 3 to No. 8 sacrificial pits began in October of 2020.

Tang Fei, chief of the Sichuan Provincial Cultural Relics and Archaeology Research Institute, said, “The new discoveries demonstrate once again that the     5     (imagine) and creation of the ancient Chinese far surpassed what people today had expected”. Tang added that the excavation of the new pits has entered a critical stage, with more     6     (item) yet to be unearthed. He also anticipated that the items found will challenge the     7     (convention) wisdom of archaeologists.

Originally discovered in     8     late 1920s, the Sanxingdui Ruins have been considered as one of the world’s greatest archaeological finds of the 20th century.     9     (locate) in the city of Guanghan, around 60 km from Chengdu, the ruins covering an area of 12 square km are believed     10     (be) the remnants (遗迹) of the Shu Kingdom, dating back some 4,500 to 3,000 years.

10 . Climate change has been a long-standing issue that continuously drives scientists to find green, sustainable fuels. The universe’s most abundant element, hydrogen (氢), has drawn their attention and is now on its way to becoming the future of green fuel.

More than $150 billion worth of green hydrogen projects were announced globally in 2020, according to Reuters. Airbus, a European multinational aerospace corporation, has taken the lead in the new sustainable fuel industry. It has designed self-contained hydrogen fuel cell pods that can be attached to the underside of airplane wings, promoting the use of hydrogen fuel for long-distance flights, which aim to achieve zero emissions. The company plans to launch hydrogen-powered aircraft in 2035, according to Daily Mail.

Compared to fossil fuels, hydrogen is a much more eco-friendly fuel. When hydrogen burns, the only by-product is water. However, the traditional way to get hydrogen from natural gas or coal generates considerable carbon emissions. The greenest way is to obtain hydrogen from water using electrolysis (电解) powered by renewable energy, although this process requires so much electricity that it is quite expensive. The key to making hydrogen competitive with fossil fuels is to lower the production cost to under $1.50. This would require lowering around 50 percent of renewable power costs and 75 percent of electrolyzer costs, according to Australia’s renewable energy agency.

Also, shipping liquid hydrogen is challenging, given that needs to be chilled to -253℃ to do so. Japan’s Kawasaki Heavy Industries is set to complete the construction of the world’s first liquefied hydrogen carrier by early 2021. According to Reuters, most of the world’s big hydrogen export projects are looking to ship hydrogen in the form of liquid ammonia (氨), which can be changed to hydrogen and needs to be chilled to only -33 C.

With more and more countries aiming to cut down carbon emissions to solve the issue of global warming, green hydrogen will help decarbonizing industries that can’t be electrified hit the targets.

“We could use these circumstances, where loads of public money are going to be needed into the energy system, to jump forward towards a hydrogen economy,” said Diederik Samsom, who heads the European Commission’s climate cabinet.

1. What is the strength of the hydrogen fuel?

A．It works very efficiently.	B．It is convenient to store.
C．It is environmentally friendly.	D．It produces no by-product.

2. What is the challenge when shipping liquid hydrogen?

A．The expensive cost of shipping.	B．The required temperature.
C．The construction of liquefied carriers.	D．Changing it to the form of liquid ammonia.

3. In which industries does green hydrogen benefit for?

A．Those powered by fossil fuels.	B．Those generating electricity.
C．Those funded by public money.	D．Those making hydrogen.

4. What is the most suitable title for the passage?

A．Fueling a Green Future	B．Living a Green Life.
C．Shipping Liquid Hydrogen	D．Making Hydrogen Competitive
