If your family or group of friends loves to bike,then a bike trip makes a perfect vacation. 1.Because you move more slowly on a bike,you have a chance to really sink into your environment,observing wildlife and views that you might miss otherwise.
As you plan your trip,the biggest decision to make is how far you'd like to travel each day.If you have unskilled bikers or kids in your group,you'll probably all be happiest if you keep your mileage goals fairly modest.2.
3. You can book campsites ahead of time at campgrounds along the way, and ride into camp as late as you like. Keep in mind that some camping equipment is heavy. Invest in a light-weight tent,and light-weight inflatable pads(充气垫）for under your sleeping bag.Dehydrated food also helps keep the weight down.
If you're going to be traveling on trails at all,you'll want to ride a mountain bike during your trip.On the other hand,if your whole route is wholly along roads,you can ride a lighter-weight street bike.Or,you can put heavier-weight tires on a street bike.4.
Biking is a great way to see the country,and if you have a lot of time,you can cover quite a bit of distance.Over the course of a multi- week trip,you'll get stronger and you'll be able to go further in one day.5. If your trip is a long one,you might want to rest a day or two early in your travels to give your body some rest.
A.An easy way to travel is to camp along the way.
B.Check in with your local bike shop for suggestions on tire weight.
C.Taking a bike trip is not only convenient but also beneficial to our health.
D.Be sure to bring the contact information and directions for each campground.
E.But a group of more experienced bikers can make more serious mileage goals.
F.Seeing the world from the seat of a bike is a wonderful way to experience new places.
G.Bear in mind, though, that early in the trip you'll start every day feeling tired from the day before.
Elephant seals in funny-looking hats are helping NASA study climate science.
Equipped with specialized sensors that resemble tiny metal hats with antennae(大线），these seals are collecting data that's helping researchers track how heat moves through ocean currents. A team of climate scientists led by Lia Siegelman used this clever technique to track changes in temperature as the seal swam the icy waters of the Antarctic.
With the help of one particularly female seal,the researchers discovered that heat stored at the ocean's depths can sometimes get swirled(打旋）back up to the surface thanks to some deeply penetrating(穿透）currents.While researchers have known that these currents can ferry heat downward into the ocean's interior(内部），the new findings suggest the opposite is true as well-driving a process that can warm the sea's surface as well.
Siegelman thinks it's important to include this new information into existing climate models.Before seals entered the picture,scientists had a pretty limited view of what went on beneath the surface of the Southern Ocean.Here,temperatures can suddenly fall below－1℃,and thick sheets of sea ice block instruments from collecting data.All in all,it's a pretty unappealing area for underwater field work.
But none of that troubles southern elephant seals,which spend nine to ten months of each year at sea,swimming thousands of miles and diving up to half a mile beneath the ocean surface-usually about 80 times a day.
So Siegelman and her colleagues tagged a female elephant seal on the Kerguelen Islands.The researchers followed her 3,000-mile journey,during which she dived 6,333 times."Even when they sleep,they dive,"Siegelman said.“They float down like a leaf."
Combined with satellite images,the wealth of data the seal recovered gave Siegelman and her team a clearer picture than they'd ever been afforded before.It's probably safe to say that the significance of this was lost on the seal.But from the human perspective(观点），it's clear seals are filling in some massive gaps in knowledge.
1.How did the researchers collect climate data in the Antarctic?
A.By testing a high-tech hat.
B.By studying a seal's behavior.
C.By measuring the water temperature.
D.By attaching a sensor to a seal's head.
2.The new findings indicate that_
A.ocean currents can drive heat up to the surface
B.heat can be taken down into the ocean's interior
C.the warm temperatures can help seals dive deep
D.the world's waters can balance global warming
3.The researchers used seals to monitor the Southern Ocean probably because.
A.the scenery is unattractive
B.the sea floor is changeable
C.seals are aggressive hunters
D.seals are extraordinary divers
4.What can be inferred from the last paragraph?
A.Seals help us observe the unknown world.
B.Satellites are used to track human activities.
C.The ocean presents a more beautiful picture.
D.Data are analyzed for better survival of seals.
The 1953 painting"Goyita"by Rafael features his mother with a red scarf on her head,a determined look on her face,and heavy expression lines,a portrait(画像）of a working-class woman that broke from traditional ones of the time that focused largely on wealthy men.
“Goyita"is one of more than 350 paintings from Puerto Rico that Google Arts&Culture digitized(数字化）for the first time with help from"Hamilton"creator Lin-Manuel Miranda, who started the online exhibition that features works from four Puerto Rican art institutions.
The aim is to expose the world to Puerto Rican art,preserve it,and help museums in the U.S.that are struggling to exhibit paintings because of limited space and budget cuts.
Puerto Rico's artwork joins Google's current online exhibitions and stories from around the world.As part of the project,Google brought its so-called"art camera"for the first time to Puerto Rico.The camera has an extremely high resolution(分辨率）thanks to a 400 millimeter zoom(镜头）that uncovers details invisible to the human eye,including brush strokes(笔法）。It also allowed those at the Institute of Puerto Rican Culture to find the signature of a pioneering female artist.
The camera took thousands of pictures to digitize 48 pieces of Puerto Rican art as it went inches by inches to cover an entire painting,a job that took 30 minutes to several hours depending on the size of the artwork,said Simon Delacroix,U.S.lead for Google Arts&Culture.
As Mr.Delacroix showed the power of the zoom on a painting called"El Gobernador Don Miguel Antonio de Ustariz",a collective"Wow"escaped from the audience attending the project at the Museum of Puerto Rico.The crowd could appreciate details in the background including someone that appears to be laughing from a balcony.
Google Arts&Culture already allows users to explore more than 2,000 museums and historic sites including Nelson Mandela 's prison cell.In total,it offers more than 6 million photos,videos,and other documents.
1.What do we know about the painting"Goyita"?
A.It is a traditional portrait. B.It is a painting by Miranda.
C.It describes a wealthy man. D.It features a working-class woman.
2.What does a Google camera uncover about Puerto Rico's artwork?
A.Its world-famous stories. B.Its humour and complexity.
C.Its depth and richness. D.Its historical backgrounds.
3.How did the audience feel the power of the zoom?
A.Amazed. B.Terrified. C.Confused. D.Disappointed.
4.What's the best title for the text?
A.Google bans its painting show B.Google digitizes Puerto Rican art
C.Google helps museums to survive D.Google launches its high-tech camera
Every Christmas,the firm I worked for raised money for disadvantaged kids in the area,and every Christmas I'd drive out with colleagues to deliver gifts.Some years ago, we were returning to work and stopped at an intersection as the lights turned red.
We were in the middle lane and I became aware of an SUV(越野车）coming up behind us at speed;at the last moment,it switched to the righthand lane and carried straight on past the red light into traffic moving west to east.It crashed into another vehicle,causing it to veer off(转向），then they both skidded to a stop.
There was a loud"Bang"and flames leapt from the SUV 's front.I had been a volunteer firefighter for many years and had attended automobile accidents before.As the flames grew fiercer,I knew the car's battery had exploded and that there was no time to lose.I dashed round to the passenger side.The door was locked,but by pulling on the window frame,I managed to tear it open.I leaned in,unbuckled the driver's belt and pulled him across to the passenger side.
Other than some cuts,he was fine.I left him with my workmates and went to check on the driver of the other car,who was also unhurt.Then I headed back to the intersection, where I directed traffic around the burning vehicle until the emergency services arrived.
On the way back to work,I said to my colleagues:"What you saw,keep it under your hats,OK?"But an hour later I had a call from a friend on a local TV station."Brad,"he said,"I have a picture here that someone's sent in of you helping out at a traffic accident."
I hoped that would be the end f it,but the story was to have an unexpected ending. A couple of weeks after the accident,I agreed to a televised reunion with Michael Walker, the guy I'd pulled from the car.He thanked me,and then he introduced me to his daughter, Amber.It turned out she had been separated from her mum and dad,but returned home after the accident.Knowing this family had been reunited was greatly comforting to me-a real Christmas gift.

C.Keep it secret. D.Bear it in mind.
4.What was a real Christmas gift to the author?
A.The reunion with the saved driver.
B.Acquaintance with Michael' s daughter.
C.Raising money for disadvantaged kids.
D.Michael' s family reunion after the accident.
