One possible version:
Yesterday, I participated in the annual Foodie Carnival launched by our school to enrich
our school life and improve our general competence.
There were numerous activities related to tasty delicious foods around the globe,varying
from cooking dishes by ourselves to listening to a lecture on a healthy diet. What impressed
us most was the cuisine cooked by each class, many being both nutritious and delicate.
Furthermore, a professor from Zhejiang University delivered a lecture, from which we
acquire much knowledge about eating healthily.
This carnival turned out to be a great hit. Consequently, I highly recommend you to
engage in it next year!

NewApp Helps People Remember Faces
Large gatherings such as weddings and conferences can be socially overwhelming. Pressure to learn people's
names only adds to the stress. A new facial-recognition app could come to the rescue, but privacy（隐私）experts
suggest to use it with caution.
The app, called SocialRecall, connects names with faces via smartphone cameras and facial recognition,
potentially avoiding the need for formal introductions. “It breaks down these social barriers we all have when
meeting somebody," says Barry Sandrew, who created the app and tested it at an event attended by about 1,000
people.
After receiving an invitation to download SocialRecall from an event organizer, the user is asked to take two
selfies and sign in via social media. At the event, the app is active within a previously defined geographical area.
When a user points his or her phone camera at an attendee's face, the app identifies the individual，displays the
person＇s name， and links to his or her social media profile（简介）.To protect privacy, it recognizes only those
who have agreed to participate. And the app's creators say it automatically deletes users' data after an event.
Ann Cavoukian,a privacy expert who runs the Privacy by Design Center of Excellence praises the app's
creators for these protective measures. She cautions, however, that when people choose to share their personal
information with the app, they should know that “there may be unintended consequences down the road with that
information being used in another context that might come back to bite you.”
The start-up has also developed a version of the app for individuals who suffer from prosopagnosia, or “face
blindness,” a condition that prevents people from recognizing individuals they have met. To use
this app, a person first acquires an image of someone's face, from either the smartphone's camera or a
photograph, and then tags it with a name. When the camera spots that same face in real life, the previously stored
information is presented. The collected data are stored only on a user's phone, according to the team behind the
app.
31.Which task can SocialRecall complete according to the text
A. Drawing pictures. B. Organizing events.
C.Identifying people. D.Chatting with friends.
32.What does the underlined word “display" mean in Paragraph 3
A.Acquire. B.Show. C.Export. D. Determine.
33.What is Paragraph 3 mainly about
A.How the app works.
C. What makes the app popular.
B.How the app was created.
D.What people can do with the app.
34. How does SocialRecall help people with prosopagnosia
A. By collecting information previously put in the phone
B. By giving names to the photos kept in their smartphones
C. By providing the information of a person when they first meet
D. By showing the person's information when it spots a stored face
35.What can we learn about SocialRecall from the passage
A. It's praised for its protective measures.
B. It has caused unintended consequences.
C.It can prevent communication disorders.
D. It might put people's privacy at risk.

How Can I Fight Laziness
Lazy people will never amount to anything in life. However, laziness can be defeated once a
few changes have been made in your mind.
36 Many people lack sleep constantly, since they stay up too late and get up too early to
prepare for work. These people have little motivation once they arrive home. Laziness works hand
in hand with a lack of motivation and a tendency to put off things. By adjusting your sleep
schedule to provide a few more hours of meaningful rest, you can fight laziness throughout the
day.
Another way to fight laziness is to change your mind from passive to active. Some people
treat their lives as if they were pushed from task to task.Others take a more proactive approach,
viewing each task as a challenge they must overcome alone.37
Some people fight laziness by removing the temptations that surround them. A television in
the living room may provide entertainment, but watching too much TV often contributes to
laziness. 38 Complete a few tasks and reward yourself with what you enjoy, such as a good
dinner or a film.
Laziness can also be a lasting problem at home. Couples and children may all have different
energy levels, but laziness can be spread if not dealt with immediately.39 Be the first to collect and
wash dishes after a meal. Others in the home may eventually follow your example and perform
their own task. It is difficult to practice laziness when you are surrounded by motivated people.
40 Enough exercise and a balanced diet can help you to develop a healthy lifestyle,
thus enabling you to have more energy and help lift your spirits.
A. To fight family laziness, set an example.
B.Knowing how to fight laziness is important.
C. One way to fight laziness is to get enough sleep.
D.Laziness sets in when you no longer control your own life.
E.Finally, taking exercise regularly can help you fight laziness.
F. With strong determination, you will be able to achieve your goal.
G. Create a reward system for yourself, just as parents do for a child.

“Every cloud has a silver lining.＂ It drives me crazy when Mom says nonsense（废话）like
that.
I'd barely had time to arrange myself in the passenger seat, my foot already blown up like a
balloon when she came out with it, exactly like I knew she would. First, she patted my leg. Then
she just couldn't help herself, “Every cloud has a silver lining, you know, sweetheart." “Mom, I
appreciate the thought, but I'm not ready to look on the bright side of this.” We hadn't even left the
school parking lot yet.
On the farthest side of the field, I could see my teammates doing sprint training, Coach Zito
striding back toward them. He'd mercifully helped me to the car in silence. Unlike Mom, he knew
when it was best to say nothing.
As Mom started the engine, I imagined my teammates cooling down without me while they
listened to Coach Zito's pep talk. And next Thursday, they would go to practice without me, and
the Thursday after that. When I had fallen and twisted my ankle, I'd cried from the pain, but I was
crying out of self-pity in the car. Hours and hours of training， and then this. I told myself there
was a glimmer （微光）of hope that everything would turn out okay, and that I'd make it to the
track meet next month, but I knew it was just that: a glimmer. The tears fell hot and fast. Mom
gave me a weak smile. “It'll be okay, Casey." I suspected this was another version of the silver
lining thing, but I felt so miserable that I let it pass.
We finally arrived at the hospital. Doctor Van gently moved my ankle around a bit before
carefully lowering it. I nervously asked how long it would be before I could run. “Four weeks
maybe, possibly five, “he replied. “And even then, you'll need to take it easy for a while. Is that
possible ” he asked with a smile.
I couldn't answer.41.
.
.
One month later, I made my appearance on the field.42.
.
.
A. Five weeks meant little chance for me to the track meet. Looking down at my swollen foot,
I wept bitter tears, knowing my last glimmer of hope was fading. As usual, Mom patted me on the
shoulder and said with a smile, “sweetheart, every cloud...”“No...”I interrupted her impatiently.
Life seemed dull and meaningless, but touched by Mom's great help, I regained my confidence
and was back on my feet. Amazingly, I began to practice running soon.
B. I was lying calmly on the bed. Seeing my mother come into the ward（病房），I greeted her
with a smile. When she asked what happened, I told her I was not going to play sports anymore.
After hearing my words about the accident, she was quite surprised how I could still remain so
optimistic. I patted my mom on the shoulder and comfort her. In my view, it is a great opportunity
to have a good rest and rethink about my future life.
C. I saw my doctor carrying the medical bag and waiting for me. He explained, “I came here
to see my patient. “The delighted man warmly welcomed me, asking me whether I conducted a
thorough examination and suggested appropriate following-up care. I thanked him with gratitude.
Before he left, my mother came, asking, " How did you know to come to see my son I didn't
call!”
D. All my teammates were absolutely astonished at my quick recovery, not believing their
eyes. “OH, boy! What a miracle!” My coach Zito looked at me in disbelief. To tell them
everything was okay, I kicked, jumped and ran in front of them. Seeing this, they all burst out
laughing. Later, I went to practice with them and participated in the track meet. From then on,
whenever I encountered difficulties, Mom’s encouraging words “Every cloud has a silver lining"
always rang in my ears.
