What is the nature of the scientific attitude, the attitude of the man or woman who studies and applies physics, biology, chemistry, geology, engineering, medicine or any other science?

We all know that science plays an important role in our societies. However, many people believe that our progress depends on two different aspects of science. The first aspect is the application of the machines, products and systems of knowledge that scientists and technologists develop. The second is the application of the special methods of thought and action that scientists use in their work.

What are these special methods of thinking and acting? First of all, it seems that a successful scientist is curious - he wants to find out how and why the universe works. He usually pays attention to problems which he notices have no satisfying explanation, and looks for relationships even if the data available seem to be unconnected. Moreover, he thinks he can improve the existing conditions and enjoys trying to solve the problems which this involves.

He is a good observer, accurate, patient and objective（客觀的） and uses the facts he observes to the fullest. For example, trained observers obtain a very large amount of information about a star mainly from the accurate analysis of the simple lines that appear in a spectrum（光譜）.

He does not accept statements which are not based on the most complete evidence available. He rejects authority as the only basis for truth. Scientists always check statements and make experiments carefully and objectively.

Furthermore, he does not readily accept his own idea, since he knows that man is the least reliable of scientific instruments and that a number of factors tend to disturb objective investigation.

Lastly, he is full of imagination since he often has to look for relationships in data which are not only complex but also frequently incomplete. Furthermore, he needs imagination if he wants to guess how processes work and how events take place.

These seem to be some of the ways in which a successful scientist or technologist thinks and acts.

It is easy for us to tell our friends from our enemies. But can other animals do the same? Elephants can! They can use their sense of vision and smell to tell the difference between people who pose a threat and those who do not.

In Kenya, researchers have found that elephants react differently to clothing worn by men of the Maasai and Kamba ethnic groups. Young Maasai men spear animals and thus pose a threat to elephants; Kamba men are mainly farmers and are not a danger to elephants.

In an experiment conducted by animal scientists, elephants were first presented with clean clothing or clothing that had been worn for five days by either a Maasai or a Kamba man. When the elephants detected the smell of clothing worn by a Maasai man, they moved away from the smell faster and took longer to relax than when they detected the smells of either clothing worn by Kamba men or clothing that had not been worn at all.

Garment color also plays a role, though in a different way. In the same study, when the elephants saw red clothing not worn before, they reacted angrily, as red is typically worn by Maasai men. Rather than running away as they did with the smell, the elephants acted aggressively toward the red clothing.

The researchers believe that the elephants’ emotional reactions are due to their different interpretations of the smells and the sights. Smelling a potential danger means that a threat is nearby and the best thing to do is run away and hide. Seeing a potential threat without its smell means that risk is low. Therefore, instead of showing fear and running away, the elephants express their anger and become aggressive.

A. Elephants attack people who wear red clothing.

B. Elephants use sight and smell to detect danger.

C. Scientists are now able to control elephants’ emotions. 

D. Some Kenyan tribes understand elephants’ emotions very well.

37. What can be inferred about the elephant’s behavior from this passage?

A. Elephants learn from their experiences.

B. Elephants have sharper sense of smell than sight.

C. Elephants are more intelligent than other animals.

D. Elephants tend to attack rather than escape when in danger.

A man claiming to be a pastor(牧師) apparently tried to stiff a waiter on a tip, explaining that his work for God allowed him not to leave one.

A photo of the receipt, posted to Reddit.com, shows a bill for $34.93 with an automatic 18 percent gratuity(小費) (or $6.29) added above a blank space for an additional tip.

“I give God 10%,” the diner wrote on the receipt, scratching out the automatic tip. “Why do you get 18?” He then wrote “Pastor” above his signature, and an emphatic “0” where the additional tip would be. (The automatic gratuity, however, had already been added to the total.)

The Reddit user who submitted the image explained in the comments section that the receipt was part of a total bill for a party of 20, which is why the gratuity was automatically added.

“Parties up to eight ... may tip whatever they’d like, but larger parties receive an automatic gratuity," the server wrote. "It’s in the computer; it’s not something I do.”

The server added: “They had no problem with my service, and told me I was great. They just didn’t want to pay when the time came.”

Scribbling(亂涂) notes on receipts has become something of a trend. Earlier this month, the manager of a North Carolina Red Robin surprised an overdue pregnant woman by comping her meal.

“Once seated, a manager came up to us and started talking,” the woman's husband told Consumerist. “He was extremely friendly and jokingly asked my wife if this was her last meal before heading to the hospital.”

When the check came, a note from the manager next to her portion of the bill read: “MOM 2 BEE GOOD LUC.”

“It was a pleasant surprise and made my tired-of-being-pregnant wife a little more cheery,” the man said.

31. What did the pastor mean by saying, “I give God 10%. Why do you get 18?”

A. He was bargaining with the waiter.

B. He didn’t mean to pay the gratuity at all.

C. God gave him the privilege not to pay a gratuity.

D. The gratuity had already been paid by his friends.

32. What do you learn from the article?

A. The pastor paid ten percent gratuity of the meal to God.

B. A party of six diners can choose whatever gratuity they want to pay.

C. According to the husband, the wife enjoyed the process of being pregnant.

D. The pastor paid $34.93 in total for the meal.

33. What does the underlined word “stiff” mean?

A. amuse                 B. abuse         C. persuade           D. fail to pay

School was over and I was both mentally and physically tired. I sat at the very front of the bus because of 11 to get home. Sitting at the front makes you 12 out like a shiny coin in a pile of dull pennies.
