高三英语单项填空简单题查看答案及解析

In 1848 gold was found in California. Thousands of people rushed there to get some. Many people liked living there. But there wasn’t a whole lot between California (CA) and Missouri (MO), where the nearest trains ran. The train line to California wasn’t finished until 1869.

In I860 and 1861, the Pony Express was the fastest way to get news to and from the West. The trail that they rode was around 2000 miles long. It took most people weeks or months to ride that far. The Pony Express could make the trip in just ten days. Those speeds were unheard of at the time. So how did they do it? Well, they had a good system.

The Pony Express had 184 stations along the trail. The stations were around ten miles apart. This is about how far a horse could run at a gallop (疾驰) before tiring. The rider would switch to a new horse at each station. He would only take his mail pouch (邮袋) with him. Every 75-100 miles, the rider would get to a home station. At each home station, riders would rest. The mail never stopped moving, even while the horses and riders rested.

It was tough to ride for the Pony Express. Each rider had to weigh less than 125 pounds. Speed was the key. Most of the riders were teenage boys. They rode at a fast pace for up to 100 miles a day. If there were an emergency, one might have to ride 200 miles in a day.

The Pony Express filled an important role for a time, but it did not last. The Civil War started in April of 1861. On October 24th, 1861, the first telegraph line to California was finished. This linked them to the rest of the country. People could send messages in an instant. Two days later the Pony Express closed.

1.Which happened first?

A.The Pony Express was started. B.The American Civil War broke out.

C.The train line to California was finished. D.Settlers rushed to California to find gold.

2.How long did it take the Pony Express to send mail from CA to MO?

A.About 24 hours. B.About ten days.

C.About twenty days. D.About one month.

3.What would a rider do at the home station?

A.Give his mail to a new rider. B.Rest a while and go on riding.

C.Collect new mail for customers. D.Feed the horse and check the mail.

4.What is the author’s purpose in writing the text?

A.To prove communication industry develops rapidly.

B.To explain why horses were used to deliver mail.

C.To describe the I860 - 1861E Fastest Mail Service.

D.To tell the brave stories of the Pony Express.

190. The famous scientist began the research which       his new discoveries.

高三英语单项填空简单题查看答案及解析

No one can fail to stand in awed（令人敬畏的）admiration of the great discoveries of history-Newton’s laws of motion , Kepler’s principles of planetary movement , Einstein’s general theory of relativity . Equally awe-inspiring are artistic creations in painting , theatre , music , and literature , which have also been brought about by discovery through personal efforts . What do these extraordinary achievements of well-known scientists and artists have to do with problem solving ?

A great scientific discovery or a great work of art is surely the result of problem-solving activity . The solution to a problem , we are told , often comes to thinkers in a “ flash of insight（顿悟）” , although they may have been turning the problem over in their minds for some time . As a particular form of problem solving , these creative acts are based on the broad knowledge gained in the past , whether this be of the “ public ” sort known to science , or of the “ private ” sort known to the artist .

Many creative thinkers state that they have completely devoted themselves to the subject matter of the problem , often over fairly long periods of time . Indeed , it would be strange if they had not done this . Nothing in such statements supports the idea that there is anything very different about the problem solving that leads to discoveries of the great contributions to the society . The act of discovery , even in the relatively predictable（可以预见的）sense that it occurs in everyday learning , involves（涉及）a “ sudden insight ” which changes the problem situation into a solution situation . As we have seen , everyday discovery also requires that the learner have the knowledge of the rules gained in the past , which is involved in the solution .

1.Newton , Kepler and Einstein are mentioned in the first paragraph to ________ .

A. bring about the subject of the discussion    B. explain that scientists are more creative

C. show the difference between science and arts D. prove that arts require more personal efforts

2.While knowledge from the past plays an important role in their achievements , thinkers sometimes also depend on their ________ .

A. artistic tastes                              B. sudden insight

C. admiration of discoveries                    D. scientific experiments

3.What does the underlined word “ this ” refer to ?

A. Great contributions to the society .         B. Long-time study of the subject matter .

C. Various statements about problem solving .   D. Complete devotion to artistic creation .

4.We may conclude from the passage that ________ .

A. it is more likely to make scientific and artistic discoveries in everyday learning

B. a sudden insight and knowledge from the past are required in making discoveries

C. scientific discoveries or artistic creations are usually unpredictable in nature

D. knowledge of the rules in the past is often developed in the changes of situation
