Do you know some great inventors and their inventions?

What factors (因素) are needed for their success?

Well, good timing for a start. You can have a great idea which the public simply doesn’t want ... yet. The Italian Giovanni Caselli invented the first fax(传真)machine in the 1860s. Although the machine was excellent, his invention quickly died a commercial(商业的) death. It was not until the 1980s that the fax became very common in every office... too late for Giovanni Caselli.

Money also helps. The Frenchman Denis Papin (1647-1712) had the idea for a steam engine (蒸汽机)almost a hundred years before the better-remembered Scotsman James Watt was even born... but he never had enough money to build one.

You also need to be patient (it took scientists nearly eighty years to develop a light bulb which actually worked)... but not too patient. In the 1870s, Elisha Gray, a professional inventor from Chicago, developed plans for a telephone. Gray saw it as no more than “a beautiful toy”. However, when he finally sent details of his invention to the Patent Office(专利局) in February， 1876, it was too late. Almost the same invention had arrived two hours earlier... and the young man who sent it, Alexander Graham Bell, will always be remembered as the inventor of the telephone.

Of course what you really need is a great idea—but if you haven’t got one, a walk in the country and careful look at nature can help. The Swiss scientist, George de Mestral, had the idea for Velcro（魔术贴）when he found his clothes covered in sticky seed pods after a walk in the country. During a similar walk in the French countryside some 250 years earlier, Rene Antoine Ferchault de Reaumur had the idea that paper could be made from wood when he found an abandoned wasps’ nest（蜂巢）.

You also need good commercial sense. Willy Higinbotham was a scientist doing nuclear（核能的） research in the Brookhaven National Laboratory in Upton, USA. In 1958, the public were invited to an exhibition in the Laboratory to see their work, but both parents and children were more interested in a tennis video game on the screen. Soon hundreds of people were ignoring the other exhibits to play the first ever computer game—made from a simple laboratory instrument called an “oscilloscope”. Higinbotham, however, never made money from his invention: he thought people were only interested in the game because the other exhibits were so boring!

1.How many factors do inventors need according to the passage?

A. 3.　　 B. 4.　　 C. 5.　　 D. 6.

2.The word “ignoring” in the last paragraph probably means “_____”.

A. having no idea of　　 B. doing no good to

C. getting no chance of　　 D. paying no attention to

3.What can you learn from the passage?

A. Giovanni Caselli invented the first fax machine in the 1980s.

B. Denis Papin afforded to build a steam engine a hundred years ago.

C. Elisha Gray missed the chance to be the inventor of the telephone.

D. George de Mestral got an idea from a walk in a French countryside.

4.Which of the following would be the best title for the passage?

A. How to be a successful inventor

B. How to get a great idea from nature

C. How to have a good commercial sense

D. How to make money from inventions

九年级英语单选题中等难度题查看答案及解析

The view you hold for yourself greatly affects the way you lead your life. It can decide whether you become the person you want to be and whether you achieve the things you value. How does this happen? How can a simple belief have the power to change your psychology(心理) and, as a result, your life?

Believing that your qualities are carved(刻) in stone — the fixed mindset — creates a great need to prove yourself over and over. Some of us are trained in this mindset from an early age. Even as a child, I was focused on being smart, but the fixed mindset was really stamped in by Mrs. Wilson, my sixth-grade teacher. She believed that people’s IQ scores told the whole story of who they were. We were seated around the room in IQ order, and only the highest-IQ students could be trusted to collect homework, or take a note to the principal. She was creating a mindset in which everyone in the class had one important goal-look smart, don’t look stupid.

I’ve seen so many people with this one important goal of proving themselves — in the classroom, in their careers, and in their relationships. Every situation calls for a confirmation of their IQ, personality, or character. Every situation is evaluated(评价): Will I succeed or fail? Will I look smart or stupid? Will I feel like a winner or a loser?

But doesn’t our society value IQ, personality, and character? Isn’t it normal to want these qualities? Yes, but ...

There’s another mindset, the growth mindset, which is based on the belief that your basic qualities are things you can develop through your efforts. Although people may differ in every which way — in their inborn talents, interests, or characters, everyone can change and grow through efforts and experience. Did you know that Darwin and Tolstoy were considered ordinary children? That the photographer Cindy Sherman, who has been on almost every list of the most important artists of the twentieth century, failed her first photography course? That Geraldine Page, one of our greatest actresses, was advised to give it up for lack of talent?

You can see how the belief that valuable qualities can be developed creates a passion(热情) for learning. Why waste time proving how great you are, when you could be getting better? Why hide weaknesses instead of overcoming them? And why seek out the tried and true, instead of experiences that will better you? The passion for improving yourself and sticking to it, even when it’s not going well, is the feature(特征) of the growth mindset. This is the mindset that allows people to achieve success during some of the most challenging times in their lives.

1.According to Paragraph 5, the example of Darwin and Tolstoy shows that _________

A.success has nothing to do with natural gifts.

B.it’s difficult to predict one’s future success.

C.achievements can be made through hard work.

D.the valuable qualities can encourage people to learn.

2.The author strongly believes that we should _________

A.carry out an honest evaluation of our qualities.

B.see success as the only way to prove IQ or talent.

C.focus on self-development rather than self-proving.

D.believe good things will happen during difficult times.

3.The main purpose of the passage is to _________

A.lead people to take the right mindset.

B.advise people to evaluate their mindset.

C.get people to know the influence of mindset.

D.explain the differences between two mindsets.

Here are some great beach spots for your family to have some fun together.

■Galadesi Beach, Florida

To be honest, you'll hardly be alone here. Caladesi Island State Park is home to hundreds of birds nesting(栖息) among the sunflower-flecked small hills of sand. On the other hand, there is not a parking space in sight.

How to Get There: The park, off the west coast, can be gotten to by boat from Honeymoon Island State Park.

■Ruby Beach, Washington

Ruby Beach feels almost mythical(神话的),especially at low tide and in the fog. The rocks there are strange-looking, and the pools can be surprising, too

How to Get There: There's a sign seven miles north of Kalaloch on Hwy, 101. From the parking lot, follow the path through the trees, down a decline, then toward the water.

■Pfeiffer Beach, California

The rocks there are amazing. In some places, the sand is a light shade of purple. Sure, it can get windy, but that's a small price to pay for paradise.

How to Get There: The turn off is actually just past the Pfeiffer Big Sur State Park entrance, at Sycamore Canyon Rd. Drive two miles to the beach, and then walk 10 minutes north to Deer Canyon. There's no sign, but you'll know it when you see it.

■High Bar Harbor, New Jersey

It sits on Long Beach Island, one of the most popular Jersey shores. But watch the water when the tide(潮汐）comes in, you may not be able to leave until the tide goes.

How to Get There: Take Long Beach Blvd. north into the town of Barnegat Light and turn left on 20th St. ,a. k. a. Auburn Road Go a 1/3 of a mile, and then turn right at the Y-shaped crossing onto Sunset Blvd. Take it to the end. You'll see a footpath( 脚印）to the beach.

A. meet a windy day B. see some red sands C. see lots of birds D. see a parking space
