20.You've probably heard of working dogs that help police officers,or horses that help farmers.Did you know that carrier pigeons(信鴿)can be trained to help people too?Here are some examples.
Mailman
Carrier pigeons can be trained to carry messages to people.The note is placed into a small can.The can is tied to the pigeon's leg.Then the pigeon flies off with the note.
Lifeguard
From high up in the sky,specially trained pigeons can find orange life jackets in the ocean.Sometimes it is difficult for humans to find people lost at sea,especially when the weather is bad.However,pigeons can fly quickly over a large area of water to look for people.
Spy
Many years ago,carrier pigeons were used to help our country during wars (戰(zhàn)爭(zhēng))."Spy pigeons"had small cameras that were tied to their feet.As a pigeon flew over enemy (敵人)land,the camera took photos of the land below.This would allow our soldiers to see where the enemies were and what they were doing.
So next time you see a pigeon,stop and watch it closely.What might look like an ordinary bird to most people,might actually be helpful.
5.What kind of people can the carrier pigeons find?A
A.The people in orange life jackets at sea.
B.The people in red jackets in the boats.

B.A pigeon was tied with a small camera around its leg.
C.A pigeon could help us to know the number of the enemy.
D.A pigeon carried the camera to take photos of the enemy land.
7.What kind of jobs are mentioned for a carrier pigeon?A
A.A mailman,a lifeguard and a spy.
B.A trainer,a spy and a police officer.
C.A soldier,a police officer and a mailman.

C.To tell readers about real jobs held by carrier pigeons.
D.To share science fictions about pigeons helping people.

10.China-A senior business official has expressed the hope that stronger economic ties between China and the Association of Southeast Asian Nations will not be affected by territorial rows in the South China Sea.
"China is not willing to see an impact on economic and trade cooperation between China and ASEAN by the South China Sea dispute,which would be harmful to both sides,"said Xu Ningning,executive deputy secretary-general of the China-ASEAN Business Council. But he did express concern that rising bilateral investment between China and ASEAN members may suffer if the situation continues to get worse.
Speaking at an awards ceremony for Chinese and ASEAN enterprises,Xu warned that Chinese an d Southeast Asian investors may be concerned about their investment return if the tension continues. He said that although governments will try to maintain bilateral investment growth between China and ASEAN,it's up to the enterprises to choose their investment destinations and make specific investment plans,especially under sensitive conditions."A closer economic relationship and more comprehensive trading cooperation will promote political relations of mutual trust between China and ASF,AN,"Xu said.

8.If you live in a big city,there are many things to drive you crazy on your daily route,and it's not just overcrowded subway trains.
Vicky Zhao is a mainlander working in Hong Kong.For her,one thing she can't put up with is people standing on the wrong side of the escalator(自動(dòng)扶梯) in subway stations."Escalators help us move faster and save time.It isn't a place to rest,"the 24-year-old says."I often see tourists block the way with their suitcases or chatting on the escalators during rush hours.It annoys me to no end."
Admitting she is not the patient type,Zhao says things are much better in Hong Kong than in cities on the mainland where"stand right,walk left"signs are often ignored.
The logic behind the"stand right,walk left"escalator etiquette(禮儀) seems obvious.Even though you may want to catch your breath while you're transported up or down,you should still consider others and leave enough space for people in a hurry,so that they can run and catch the train.
Many cities'escalators,including London's and Beijing's,use the"stand right,walk left"system to speed up the flow of people.(Australia is an exception and you should stand on the left side instead.) But some cities discourage people from moving on escalators out of safety reasons.In Hong Kong's subway stations there are regular announcements asking people to"stand still"on escalators.Even so,most people in this fast-paced city observe the"stand right,walk left"etiquette.
But the people who stand on escalators defend themselves by telling the walkers not to be so impatient.The BBC quotes one stander as saying:"If the person is in such a rush,why not just take the stairs?Even when the escalator is packed and there's nowhere to move,I see these same people complaining about not being able to pass."
Whatever the escalator etiquette is in the place you live or visit,do what most people are doing and always be mindful of others:leave enough space between each other,don't stay at the end of the escalator,and if someone is blocking your way,a simple"excuse me"is enough.
33.In the second paragraph,the underlined word"It"refers toC.
A.the author's living in the big city of Hong Kong.
B.being crowded on the subway trains in rush hours.
C.people's blocking the way or chat on the escalators.
D.people's standing on the right side resting.
34.When on the escalator,a majority of local people in Hong KongD.
A.stand still as the railway stations require.
B.ignore the"stand right,walk left"signs
C.use the stairs instead of escalators.
D.follow the"stand right,wail left"etiquette.
35.Which of the following statements is the writer's opinion?B
A.People should stand right no matter where they are.
B.People should do as the Romans do and consider others.
C.People should do as they like on the escalators.
D.People should be seriously criticized when they block the way.

9.Many fourth graders would panic in an emergency situation,(61)yet/but  one Pennsylvania nine-year-old is being called a hero after discovering a  (62)dying  (die') man and knowing exactly what to do to save his life.This past Friday,Owen Sambol  (63)was heading(head) home,from school on a cold,snowy day when he heard a faint noise that sounded like someone crying for help.(64)Without  hesitating,he ran behind the house to see where it was coming from and discovered  (65)a  man lying face down in the snow.
The little boy tried his(66)hardest (hard) to pull the man up,but he wasn't strong enough.Instead of panicking,he told the man he would get his mother,(67)who  is afire-fighter,and come right back for him.Mom Ashley Sambol called 911 right away,then pulled the man up and carried him into her home because she was afraid he had hypothermia(低體溫)after(68)being left/having been left(leave)in the snow for so long.
"I take(69)pride (proud)in him,"Ashley said about her son,who stayed calm and saved a life that afternoon."Had he been out there any longer and who knows.''(70)Thankfully(thank),the man was rescued just in time and is now healing in the hospital.
