10.Imagine looking at a view of mountaintops and wondering about the name of each peak.Suddenly,above each mountaintop,a name appears on the sky.The words are not written in smoke by skywriting planes.The words are actually not in the sky at all.They come from tiny computers in contact lenses(隱形眼鏡).
Computers have become smaller and smaller over the decades.The first computers filled houses.Transistors(晶體管) and then chips allowed computers to become small enough to fit on a desktop,then a laptop,and finally a phone.When experimenting with further reductions in size,developers often have to deal with the limits of human eyesight,which control how small the computers can be and still present visible information.
One new solution employs microprojectors(微型投影機(jī)) to create a readable display(顯示) for tiny computers.These machines project computer information onto any surface.Though an impressive breakthrough,there are potential problems.Such public displays can lead to privacy concerns; most people do not want their information displayed on a wall for everyone to see.Besides,these projectors are extremely expensive,and their screens give users headaches.
Babak Parviz,a researcher at the University of Washington,created another solution:inventing a screen visible only to a person wearing a contact lens.Parviz created a computer in a contact lens that uses the wearer's field of vision as the display.To create the display,Parviz took ordinary soft contact lenses with a wirelessly controlled system.At some point,Parviz says,it will be possible to connect the lens to a remote personal computer device such as a cellphone or a laptop.By looking in a certain direction,the wearer sends the computer visual information about what he or she sees.The device then uses this information to point out the names of peaks.
These contact lenses are inserted and removed in much the same way as ordinary contact lenses.In addition,the computers in the lenses won't block the wearer's sight at all.Although now the computers are not on lenses treating eyesight problems,Parviz hopes that someday the technology will progress to that level.

63.The contact lenses in the text canD.
A.treat eyesight problems
B.offer beautiful views of nature
C.project information on wall surface
D.show information about what wearers see

A.saving users'expenses
B.reducing computers'size
C.limiting the field of vision
D.guarding remote computers
66.What might be the best title for the passage?A
A.Tiny Computers,Amazing Sights
B.Smaller Lenses,Closer Views
C.Progress towards Clearness
D.Road to the Small World.

When enjoying children's birthdays or a long-expected family holiday,you may usually want to keep those important moments in mind with a photograph.But if you’re one of those people who can’t stop snapping photos at an important event,be aware--you could end up forgetting it all in a flash.

Experts have warned that the addiction to recording every moment of our lives could be having an adverse effect on our memories.

Maryanne Garry,a New Zealand psychology professor,has been studying how the frequent taking of photos might change childhood memories.I think the problem is that people are forgetting to experience the moment,she says.Parents at the park taking one photo after another of their children,for example,are actually paying less attention to what is happening around them.The picture only captures a small part of the total experience.And because parents remember less about these important events,they become less effective in their role as the key people who help children learn how to talk about their experiences.As a result,children's own childhood memories are reduced.

The idea that we are experiencing less as we record more got psychologist Linda Henkel’s thinking.She wanted to explore how photographs shape our memories.

Henkel,who researches human memory at Fairfield University in Connecticut,did an experiment by sending groups of students to the university’s art museum.The students observed some objects and photographed others. Then,back at the laboratory,they were given a memory test.Henkel found what she called a “photo-taking effect”.The students remembered fewer of the objects that they had taken photos of,and they remembered fewer details about those objects.She says her students’ memories were worse because they were relying on the camera to remember the details for them.

“As soon as you hit ‘click’ on that camera,it’s as if you’ve decreased your memory.” she says.

1.What does the word “it” in Paragraph 1 refer to?

A. A child’s birthday.

B. An important event.

C. A valuable photograph.

D. A family holiday.

2.How did Henkel develop her theory about the “photo-taking effect”?

A. By carrying out an experiment.

B. By giving a questionnaire.

C. By interviewing a group of students.

D. By researching the findings of the others.

3.According to Paragraph 3,why are children’s memories reduced?

A. Flash lights are causing children to forget more things.

B. Parents are into listening to children’s experiences.

C. Children are more into taking photos than experiencing.

D. Parents are less effective in helping children discuss their experiences.

4.What’s the purpose of this passage?

A. To introduce a new discovery in taking photos.

B. To discuss the effect of photo-taking on memory.

C. To explain how to use cameras in an effective way.

D. To describe the ways of remembering valuable experiences.

Every day,in all kinds of weather,a lot of men or women go jogging (慢跑).(61)Why is jogging so popular?為什么慢跑如此流行呢?Most people start jogging because they hear it is a very good form of exercise.Jogging makes the heart strong and helps people control their weight or stay slim.If you keep jogging regularly,(62)It is unnecessary for you to take medicines.你沒必要服藥 or skip meals to lose weight.(63)慢跑還能使你對(duì)自己感覺更好.Jogging can also make you feel better about yourself.
Donald Robbins,who is 42years old and works in an office,began jogging a few years ago because he was overweight.At first,(64)他只能跑300米左右.he could only run about 300 meters,but two years later,he ran a marathon-over 42kilometers.
Do you jog?If you do,be sure to ask your doctor for advice.(65)慢跑幾乎不耗費(fèi)你任何東西Jogging costs you almost nothing.But it is very important to have a pair of good shoes that are made especially for jogging.If not,when you run on hard ground for a long time,it may cause your feet to hurt.

Like all of us,I am heartbroken with sadness whenever I read another news story about a hot car tragedy(36)FWhile all of us may wonder how this could happen so frequently,from what I've read it's most often due to either kids getting into cars without parents'notice,or parents forgetting a child in the backseat.(37)DThis is because their body temperatures rise more quickly than adults'do.
It's easy to cast judgment and wonder how on earth a parent could forget their child in a hot car.But in the majority of stories I've read,there is a sleeping child in the backseat and a parent has disrupted their usual routine.(38)Cwhat I have read is to leave something in your back seat like a cell phone or handbag,or employee ID or briefcase if a parent is headed to work.It's also important to always keep your car locked,including on driveways and in garages,and to hide the keys.(39)GWhile it's hard to say anything good that can escape from these nightmares,I'd like to think that every news story raises parents'awareness about the phenomenon.(40)AI'd like to think that the incidents remind us all that if we are ever in the parking lot of a grocery store,mall,or whenever and see a child alone in a parked car,we immediately alert the store or authorities.

A.These children did not die in vain.
B.Parents are to blame for these deaths.
C.What's the best and most practical prevention tip?
D.It often doesn't take long for children to die of heat.
E.Measures must be taken to prevent children being left in cars.
F.In 2016 alone,26 children have died after being left in hot cars.
G.This way,your child cannot wander into the car without your knowing.
