【题目】 The online media group TechRadar recently made a list of "the most useful and interesting apps in 2019". Let's take a look at three of them.

Things 3

Things is an award-winning task manager. It helps users collect their thoughts and plan their time well.

The app's chief design is a to-do list. It allows users to add context (内容), such as the time, date or location that they plan to carry the task out. It then shows a "Today" view with the day's tasks, and group's things users do after work under the heading "This Evening". It puts later tasks in a list tiled "Upcoming".

StoryZ

In the age of smartphones, everyone is a photographer. From taking selfies to sharing them on social media (社交软件) , photo-editing apps play an important role in making our pictures look perfect.

StoryZ's latest version takes it a step further. The app has two modes. The fist one is "Ripple Effect (涟漪效应)", which makes still images (图像) move and come to life. It can create amazing animated photographs. Another one is "Motion Effect (动态效果) "which creates video stories on still images. It can turn your photo into animated GIF.

TaoMix

If you want to relax, sleep better or focus, the sounds of nature are an excellent choice. TaoMix allows you to listen to some soft sounds to release stress and helps you take a break from your busy life.

This white noise app provides hundreds of nature sounds. You can hear sounds of birds, waves of he sea, falling rain, blowing wind, and many more! Better yet, you are not limited to one sound. You can build a soundscape (音景)by choosing several at a time.

【题目】

It has been a dream for 30 years but now the world’s first flying car is set to hit the roads this year.

Ever since the “Back to the Future” movies lit up our screens in the 1980s designers have dream of cars that could take to the sky at the push of a button. And now pilots can order their own “roadable” plane for just t 127000.

The plane which has fold- out wings that span(翼展)17.5f has a range(连续的) flying distance of 460 miles and can be up to 115 mph. Back on the land it can also travel at “highway speeds” in car mode(状态)

Fuelling the 19 ft long plane couldn't be simpler-you just drive it into a petrol station and fill it up.

A spokeswoman said"You can keep your light-sport airplane in your garage. But because it needs a short runway to take to the air you will have to drive to your local airport fly up to 460 miles land and drive directly to your destination. You will always be ready to drive or fly."

The spokeswoman added "Never let bad weather change your trip. You can simply divert(改道)and continue on the ground until the weather clears.”

There’s no risk to you----this is only the chance for you to be the first at your home field to unfold your wings and fly into the future.

1According to the text the “roadable” plane____________.

A.can fly at “highway speeds” in car modeB.is a kind of car with fold-out wings

C.is 19ft long and 17. 5 ft wide insideD.can only travel on the highway

2We can infer that in the “Back to the Future” movies_________.

A.there are some skillful pilotsB.pilots have no cars to drive

C.pilots can’t afford a “roadable” planeD.cars can fly in the sky

3What does the underlined word “it” in the 5th paragraph refer to

A.The “roadable” plane.B.Your garage.

C.The local airport.D.A petrol station.

4The last sentence of the text aims to___________.

A.call for people to buy the “roadable” plane

B.show people the use of the “roadable” plane

C.tell people only the “roadable” plane can fly in the future

D.ask people to unfold their wings and fly into the future

5If you meet with a thunderstorm in your “roadable” plane in the sky you can________.

A.land in a nearby airport until it clearsB.turn back home until it clears

C.land and drive on the groundD.fly high up to 460 miles

Ping Pong Door

Do you want a ping-pong table in your room? But you may not have enough space. Now this door is here to help you. It can turn into a ping-pong table when you pull it down. After the ping-pong game is over, it goes back to being a common door. It was designed by Tobias Frnzel from Germany. Cool idea!

Dog Watch

The dog watch is a “clock for keeping time at a rate(比率) other than human time” and was invented in 1991. With this watch, you can know time at your animal’s rate instead of your own. The watch multiplies(乘)every human time by seven, giving us “doggy time”. If a dog lives to be the age of 14, that translates into 98 human years!

Earthquake House

Big earthquakes can hit a house, possibly making the people in it get hurt. But Dysinger has found a way, the Earthquake House!

His idea is simple. Build a round house that has earthquake sensors(传感器) in it. If the sensors know the big earthquake, the house is free from its chains(链条). Don’t worry. You always remain straight in it.

Smell This

How do you know if your breath smells nice, or if it smells bad? It’s difficult to know because it’s very hard to smell the air that comes out of your own mouth. Smell This is useful for this situation. You just place the mask on your face, then breathe out through your mouth and breathe in through your nose.

1The underlined word “it” in Paragraph 1 refers to __________.

A.the ping-pong gamesB.your roomC.the ping-pong tableD.enough space

2A dog watch helps _______.

A.a dog to know the timeB.to know the life of a dog

C.dogs to know the time for mealsD.to translate a dog’s age into human time

5This passage is probably from _____.

A.a novelB.a story bookC.a newspaperD.a poem

【题目】

Have you stroked (抚摸) a cute dog recently? If that dog touched you with its nose, you might find how wet and cold it was. If dogs are so warm and fluffy (毛茸茸 ), then why are their noses so cold?

Before, people thought that dogs had cold noses to help them control their body temperature. But, a new study in the journal Scientific Reports has shown some interesting findings about dogs’ noses. The study found that when the air temperature was 30 , the tip of a dog’s nose is about five degrees cooler than the air. But why is this?

The researchers believed that the tip of a dog’s nose has a special sensory function (探测功 ). So, they did an experiment to test it. The study showed that dogs could find weak heat sources—like a small animal—with their noses from 1.5 meters away.

The research team studied three dogs named Charlie, Delfi and Kevin. For the experiment, the dogs had to tell the difference between two objects. The two objects were heated to different temperatures. Amazingly, all three dogs were able to sense the temperature difference between both objects.

The study also found that the heat from the objects in the experiment “was too weak to be felt by human hands, even at very short distances”. The dogs were able to sense these heated objects from a distance, but humans were only able to feel the warmth of the object if they touched it.

To know more about it, the research team also studied the brain activity of 13 dogs. When a warm object was put near their noses, there was an increase in brain activity.

“From the two complementary (互补的) experiments, we can know that dogs are indeed able to sense heat from warm-blooded animals, and a special region of the brain is made to be active by such heat.” said Anna Balint, the leader of the study.

1What did the new study published in the journal Scientific Reports find about dogs?

A.What makes dogs loyal.B.Why dogs have cold noses.

C.How dogs feel heat better.D.How a dog’s temperature influences its brain activity.

2Which of the following words has the closest meaning to “region”?

A.Way.B.Area.C.Type.D.Change.

3What happened to the dogs when a warm object was put near their noses?

A.They showed no change in their brain activity.B.They had different kinds of excitement.

C.Their brain activity slowed down.D.Their brains became more active.

4What can we infer from the passage?

A.Heat sensing ability can help dogs hunt for food.

B.The tip of a dog’s nose has a special sensory function.

C.Dogs are smarter than other animals.

D.The two experiments found different results.
