The dream of flying like Buzz Lightyear never dies. For years, space-age inventors have tested one wearable jet pack after another. And time after time, the designs have been grounded by dangerous fuels, excessive weight, or very loud noise levels. Now a Canadian inventor has sidestepped those weaknesses with an aquatic jet pack. Designed for travel over lakes or oceans, it’s driven by pressurized water, not burning rocket fuel.
When Raymond Li first told the idea for the aquatic jet pack to his friends, they said he must be nuts. How could a jet pack carry that much water? Its thrust-to-weight rate would be so low and it would never become airborne. Thrust-to-weight rate is a measure of the forward force produced compared with the weight of the vehicle. A vehicle with a low thrust-to-weight rate is relatively heavy for the amount of force it generates.
Li's genius idea was to place the jet pack’s engine and its water pump in a separate boat. The pump would draw water from the lake the boat was floating on. It would then force the water under pressure through a hose connected to the jet pack. The hose would be long enough to let the pack go up as high as 8.5 meters (28 feet) in the air.
Today, Li's invention, the Jetlev-Flyer, is ready to go into production. The pack itself, complete with jet nozzles （管嘴） and handlebars, weighs just 14 kilograms. The boat is a floating pod. To take off, the operator hits a trigger on a handlebar, which starts the pump, and then turns the throttle. Two streams of high-velocity water shoot through the hose and out the nozzles, lifting the operator into the air. The operator hovers there or pushes down on the handlebars, zooming forward at speeds of up to 64 kilometers per hour, pulling the pod behind.
61. All the following factors contribute to the failure of inventing a wearable jet pack EXCEPT ______.
A. excessive water B. unbearable noise C. unsafe fuels D. too much weight
62. The underlined word “sidestepped” in Para. 1 most probably means ________.
A. improved B. reduced C. avoided D. solved
63. Raymond Li’s friends found his idea for the aquatic jet pack was ________.

64. Which of the following is TRUE according to the passage?
A. His friends encouraged him to do the invention.
B. He put the engine and its water pump in the same boat.
C. The success of his invention lies in his bravery.
D. His invention finally succeeded and will go into production.
65. Which is the right order to make the Jetlev-Flyer take off?
a. The throttle is turned. b. The operator is lifted into the air.
c. A trigger is hit. d. Two streams of water shoot out.
e. The pump is started.

Dear Dad,
Today I was at the shopping mall and I spent a lot of time reading the Father's Day cards. They all had a special message that in some way or another reflected how I feel about you. Yet as I selected and read, it occurred to me that not a single card said what I really want to say to you.
You'll soon be 84 years old, Dad, and you and I will have had 55 Father's Days together. I haven't always been with you on Father's Day but I've always been with you in my heart.
You know, Dad, there was a time when we were separated by the generation gap. You stood on one side of the Great Divide and I on the other.
The Father-Daughter Duel shifted into high gear ( 档位) when you taught me to drive the old Dodge and I decided I would drive the '54 Chevy whether you liked it or not. The police officer who sent me home, after you reported the Chevy stolen, didn't have much tolerance for a stubborn 16 year old, while you were so tolerant about it, Dad, and I think that was probably what made it the worst night of my life.
Our relationship greatly improved when I married a man you liked, and things really turned around when we began making babies right and left. Somewhere along the line, the generation gap disappeared. I suppose I saw us and our relationship as aging together, rather like a fine wine.
But the strangest thing happened last week. I was at a stop sign and I watched as you turned the corner in your car. It didn't immediately occur to me that it was you because the man driving looked so elderly and fragile behind the wheel of that huge car. It was rather like a slap in the face delivered from out of nowhere. Perhaps I saw your age for the first time that day.
I guess what I'm trying to say, Dad, is what every son and daughter wants to say to their Dad today. Honoring a father on Father's Day is about respect and sharing and acceptance and tolerance and giving and taking. It's about loving someone more than words can say, and it's wishing that never had to end.
I love you, Dad.
Love,

Pulling heavy suitcases all day in the summer is hard work, especially when you are a thin 14-year-old boy. That was me in 1940-the youngest and smallest baggage boy at New York City's Pennsylvania Railway Station.
After just a few days on the job, I began noticing that the other fellows were overcharging passengers. I'd like to join them, thinking, "Everyone else is doing it."
When I got home that night, I told my dad what I wanted to do. "You give an honest day's work," he said, looking at me straight in his eye. "They are paying you. If they want to do that, you let them do that."
I followed my dad's advice for the rest of that summer and have lived by his words ever since.
Of all the jobs I've had, it was my experience at Pennsylvania Railway Station that has stuck with me. Now I teach my players to have respect for other people and their possession. Being a member of a team is a totally shared experience. If one person steals, it destroys trust and hurts everyone. I can put up with many things, but not with people who steal. If one of my players were caught stealing, he'd be gone.
Whether you're on a sports team, in an office or a member of a family. if you can't trust one another, there is going to be trouble. What can be inferred about the baggage boys?
| A．They could earn much, but they had to work hard. |
| B．Many of them earned money in a dishonest way. |
| C．They were all from poor families. |
| D．They were thin, young boys. |
What does the father's advice imply?

Say you're in the wine store and you want to buy something new. You have nothing to go by outside of the label. Will the label tell you anything you should know? Here's some general advice:
Vintage. This is the first thing we look for ourselves. You don't need to care whether 2001 or 2002 was a better year in the Sierra Foothills. The vast majority of wines at the store are meant to be drunk right away, so you make sure the wine isn't too old, particularly if you're buying it expecting lively, fresh fruitiness. We often see five-year-old Pinot Grigio and two-year-old Beaujolais Nouveau at stores, for example, so as soon as we see that kind of age on wines like those, we know we can skip them and move on(and possibly not shop there again).
Alcohol content. Too many wines have too much alcohol, which leaves them unbalanced. Sure, there are some classic wines with high alcohol levels, but many of today's regular table wines--Merlot, Chardonnay--have levels at 15% or above. Some of those might be terrific, but if we had nothing else to go on, we'd look for alcohol content at about 14% and below.
The more specific the better. A wine that says it's from Napa is probably a better bet than a wine that simply says it's from California. Unfortunately, this will also probably be reflected in the price, so this might not tell you much about value, If you care enough to know a few of famous vineyards for producing high-quality grapes, they might help you make an educated guess about quality.
Old vines. Theoretically, older vines produce fewer, but more flavorful grapes, but the problem is that no one has defined what an "old vine" is, so anyone can put this on the label. Just ignore it.
A phone number. You'd be surprised many small-production wines these days include a phone number on the back and an invitation to call the winerY, which is a sign of a highly personal winerY. We have called those numbers many times over the years and it's amazing how often the winemaker or winerY owner answers the phone. The underlined word "Vintage" in the second paragraph probably means "________ " .
| A．the place where the wine was made | B．the year when the wine was made |
| C．the freshness of the wine | D．the label of the wine |
It's better to buy
| A．five-year-old Pinot Grigio | B．the wine labeled from older vines |
| C．the wine from famous vineyards | D．two-year-old Beaujolais Nouveau |
From the passage we Can infer that
| A．the wine with high alcohol levels is definitely terrific |
| B．most wines at the store are intended to be drunk right away |
| C．older vines have lower production |
| D．some winemakers keep the promise all the time |
What is paragraph 4 mainly about?
| A．Geography. | B．Price | C．Quality. | D．Grapes. |
