No matter how much we try to be intellectual, life has its own ways of teaching us the valuable lessons. Though initially we are hurt and very shocked, we eventually learn from those experiences, and mature. 【1】 And we learn to be always optimistic and happy with the way it is.

【4】 In the race of being a perfectionist and an ideal grown-up, every mistake committed by us becomes a mistake in our minds and we become annoyed with ourselves. It is rightly said, "To err （(犯错) ）is human." We are all humans, so nobody knows everything, and it is fine to forgive ourselves for the things that went wrong. 【5】

【题目】 Robert Vallieres hikes for miles, often three times a week, climbing the high mountains, just to get a glimpse of his beloved birds.
Many years ago, as a young engineer in the army, Vallieres was struck in the head in a task in Gulf War, which ended his military career and left him fighting for his life. He was 28 years old and battled stress, survivor’s guilt and PTSD (创伤后应激障碍). “When you’re disabled and you really can’t move too much, you’re wondering if death is nearby.” he said.
Despite his condition, Vallieres still had to be a father to his little boy-a curious child who helped jump start his love for birds.
One day, his three-year-old son noticed a bird and asked his father what kind it was. Vallieres bought a bird identification book and started learning along with his son. He bought some small telescopes and the two began observing birds together near their home in New Hampshire.
Then came another turning point. Vallieres saw an ad in the newspaper for a birding trip in New Hampshire’s White Mountains and signed up.
Now it’s his joy and renewed purpose to track and save the peregrine falcon and the bald eagle-two species nearly wiped out by the chemicals used for killing pests. It’s hard physical work for anyone, which needs patience, keen observation skills and time. But Vallieres is a natural at it, because his military training made him a perfect match, especially in reading maps and navigating.
Vallieres says not only does his volunteering help with physical fitness, but also his mental state. “To find rhythm or purpose in life besides myself,” says Vallieres, “I shouldn’t get stuck on myself but have a way out.”
【1】What led to Vallieres leaving the army?
A.Life failure.B.Severe injury.
C.His son.D.Love for birds.
【2】How did Vallieres start his new rhythm in life?
A.By climbing mountains often.
B.By buying some small telescopes.
C.By strengthening the military training.
D.By signing up for protecting birds.
【3】Why is Vallieres suitable for the volunteer work?
A.For his habit of reading.B.For his experience in army.
C.For his devotion to career.D.For his talent in drawing maps.
【4】What can be a suitable title for the text?
A.A Volunteer’s Story of Saving Birds
B.An Inspiring Story of Self-motivation
C.A Soldier’s Story of Healing through Birds
D.A Moving Story Between a Father and His Son

【题目】 Sometimes while sitting doing nothing, our minds recall events from the past that make us all tingly inside. I had one of those moments yesterday. I believe this was triggered（引起）by the oldie The Impossible Dream that was playing on the radio yesterday afternoon!
In 1971, returning from our regular Friday night pregame meeting, I had no sooner walked in the door of our three-room apartment hack than the phone rang. It was the township police. They inquired if I was the football coach. I answered yes and asked if there was a problem. He said our football team had climbed the fence of the township football field and were sitting somewhere around the 50-yard line quietly. It was really not a problem. However, he thought I would like to know. I called my assistants, and made our way to the field.
We met the police at the locked gate. The field was dark and silent. Then, suddenly, we heard voices singing—together and on key—the team theme song, The Impossible Dream. Silently, we listened and became overwhelmed（压倒）with emotion. Even the policemen had tears rolling down their cheeks. When the team had finished, they walked slowly to the now-opened gate of the field and were shocked to see us waiting there. Of course, our first words were, "What is going on?"
Mike Bernert, the team captain, replied, "Well, coach, you told us to visualize our performance in our mind just before the night of the game. So we came and visualized the upcoming game while sitting on the 50-yard line. Afterward, we would sing The Impossible Dream.”
The coaches and I were overwhelmed. And of course, the team, which was undefeated at this point, never lost a game that season.
【1】What does the underlined word “tingly” in Paragraph 1 mean?
A.Frightened.B.Excited.
C.Worried.D.Puzzled.
【2】Why did the police call?
A.The team did something unusual.
B.The team had conflicts with fans.
C.The team locked themselves in the football field.
D.The team damaged the fences of the playground.
【3】How did the team feel when they saw the author and the policeman?
A.Happy.B.Sad.
C.Ashamed.D.Surprised.
【4】What is the purpose for the team to sing the song?
A.To enjoy themselves.B.To inspire themselves.
C.To celebrate their success.D.To rest themselves.

【题目】 Fishing is a great family sport，and a fun summertime activity. 【1】. If you have never fished before it can seem very complicated. Expert fishers know when and where to find certain fish and the best technique to catch each fish. Expert knowledge comes from years of experience.【2】.
As a beginner you will want to use a technique called“Bait(鱼饵)Fishing”. This type of fishing is probably the easiest technique for catching fish. You will need some basic fishing equipment，which you can get at almost any outdoor gear store. You will have to have a rod and fishing line，hooks，some bait and if you are planning on keeping the fish，you will need something to store the fish.
The best way to learn how to fish is to learn from someone who already knows，so when planning your fishing trip，be sure to bring along someone who has fished before. 【3】，you will need to decide where to go fishing. Probably for the first time you will want to go to a local lake，where the water is calm and there are plenty of fish. You should also try to research the different types of fish that live in the place you decide to fish，so you know what types of bait they like to eat and what you want to do with the fish once you have caught it.
【4】，you probably want to clean the fish，then store it before continuing fishing. If you want to release the fish，be extra careful when removing the hook，so it doesn’t get hurt too badly，then gently hold the fish in the water and allow it to swim away out of your hands.
【5】 Take some time to learn from an expert and you will be able to catch all types of fish using a wide variety of methods.
A.If you want to keep the fish
B.After you have decided to go fishing
