Dogs can be good helpers to humans and what about monkeys? They can do a great job, too. Monkeys can help disabled（有残疾的）people live a better life just as dogs do.

Like dogs, monkeys need lots of training to be human helpers. One difference is that monkeys live longer than dogs do. This means that a monkey's "childhood" is also longer than a dog's. So it may take them four to six years before they are ready to begin training.

It's said that it is almost as much work as raising a young child!

After monkeys begin training, they usually take about a year to learn enough tasks to be good helpers. One important thing that they need to learn is how to follow command (命令).

For example, if a person wants to have the lights turned on, he or she might give the command "sun". As the monkeys get better at completing their tasks, they learn new and more difficult ones. Some monkeys can even learn how to use a computer!

1.Both dogs and monkeys need lots of training before they can help humans.

A.Right.

B.Wrong

2.Dogs are ready to begin training when they are 4 to 6 years old.

A.Right.

B.Wrong

3.It usually takes monkeys about a year to learn how to become good human helpers.

A.Right.

B.Wrong

4.If a person gives the command "sun", he might want the monkey to turn on the lights.

A.Right.

B.Wrong

5.All monkeys can learn how to use computers.

A.Right.

B.Wrong

Which animals are smart? Your answer may be dogs, monkeys or elephants. Now we can put one more animal into the list: sheep.

Scientists from Cambridge University said that they can teach sheep to tell familiar (熟悉的)human faces from other unfamiliar ones.

Before testing, scientists let the sheep take a look at pictures of four famous people, such as Barack Obama and British actress Emma Watson. Then the sheep went into a room with two computer screens. Each screen showed a human face. One screen showed a famous person and the other screen showed a common person。The sheep would always walk to the screen with the face of famous persons.

Then, the scientists wanted to know the sheep's ability to recognize(认出) them from a photo. They put their own photos on screens along with some pictures of unfamiliar(不熟悉的) faces. Not surprisingly, the sheep could tell the scientists from others.

After noticing the animals' ability to recognize people, scientists gave them a new job. They wanted to see the farm animals' ability to recognize the same person if the picture only showed half of the person's face or just one side of a person. The animals were still able to recognize them, though they were a little slower to recognize the pictures than before.

The results show that the animals' face-recognition( 面部识别) abilities are similar to those of monkeys and humans. Face recognition is a difficult job. But sheep have big brains(大脑). When they see other sheep, they can also recognize one another.

The scientists said it might be interesting in the future 10 find out whether sheep can recognize different human facial expressions(表情)

Oink! The Year of the Pig is coming. How much do you know about pigs? Do you like them? Many people don't, because they believe that pigs are naturally fat, lazy and dirty. But are any of those things true?

It is true that pigs are fat. They eat a lot. But they are useful to us. We get more than just pork from pigs. We can use their skin to make shoes. We can use their hair to make brushes. Pigs also provide us with ingredients for drugs like insulin(胰岛素). Insulin can treat diabetes (糖尿病).

People sometimes say. “You are as stupid as a pig.” But pigs are not stupid. In fact pigs are one of the 10 smartest animals. They have a good memory and can tell different shapes apart. Many experts think pigs are easier to train than dogs or cats. In France, people teach pigs to find truffles(松露). With their good sense of smell, they can find truffles even faster than dogs.

When you see pigs, they are usually in dirty water or mud. That's because pigs have no sweat glands(汗腺). On hot days, they have to cool themselves in water or mud. This keeps insects away from them as well. Mud can also protect their skin from sunburns.

These stereotypes about pigs often make us hold a negative(负面的) view about the animal. For example, If someone eats a lot, we say that they have “pigged out”. If someone's room is very messy, we might say his or her room looks like a pigsty(猪圈).

But people in ancient China really liked pigs. People thought the pig's big head and ears were a symbol of good luck. If someone had a round and chubby(胖乎乎的) face, he or she was thought to be blessed(有福气的). People also believed the animal, stood for wealth, as humans use every part of the pig. Piggy banks are a symbol of this. Most children have a piggy bank that they can use to save money.

1.People can use pigs' skin to___________.

A.make clothes B.make insulin

C.make shoes D.make brushes

2.According to the passage, pigs can____________.

A.tell one hundred different colors apart. B.find truffles with their good eyesight.

C.be of great help to people like dogs. D.get away from insects with their owners' help.

3.Which of the following best explained the underlined word “stereotypes”?

A.fixed ideas B.feelings C.mistakes D.decorations

4.Why did the people in ancient China like pigs?

A.People thought pigs were blessed by God.

B.People believed the animal stood for health.

C.People knew pigs were one of the 10 smartest animals.

D.People thought pigs can bring good luck to them.

5.The writer wrote this passage mainly to_____________.

A.tell that pigs are not stupid, dirty or fat at all. B.criticize people who don't really know about pigs.

C.point out that pigs can do a lot of things for people. D.help people know more about the pigs.

Have you ever had an experience where you meet someone new, learn their name and think to yourself, "Wow, they really look just like their name!" What does this mean, exactly? Scientists are suggesting that humans tend to associate people's names with their appearance, and can even guess someone's name based on how they look.

Researchers at the Hebrew University of Jerusalem in Israel collected thousands of photos of people faces. They labeled (贴标签)each photo with four names. Then, they asked volunteers to guess which of the four names was correct.

The volunteers were able to guess the right name 38 percent of the time. It seems that humans are able to recognize certain characteristics of faces that can give them clues (线索)about someone's name, Reader's Digest reported.

However, this only works when we're looking at names within our own culture. In addition, the volunteers were not as good at guessing the real names of people who use nicknames (昵称) more often than their real names. This shows that a person's appearance is affected by their name only if they use it often.

This kind of face- -name matching happens because of a process of self-fulfilling prophecy(自我实现预言), as we become what other people expect us to become," Ruth Mayo from the university told science news website EurekAlert.

Previous studies have shown that gender and race (种族)stereotypes (刻板印象)can affect a person's appearance. The researchers believe there are also similar stereotypes about names. For example, people tend to think that men named Bob should have rounder faces because the word itself looks round,people may think that women named rose are beautiful. They expect them to be delicate and feminine, just like the flower they are named for.

1.What does the passage mainly tells?

A.People can guess others' names based on their appearance.

B.A person's appearance can be affected by three factors.

C.There are several ways to guess a stranger's name.

D.It's not polite to ask strangers about their names.

2.Dr. Ruth Mayo thinks some people look like their names because of ________.

A.racial stereotypes B.their unique culture

C.a self-fulfilling prophecy D.their living environment

3.According to the passage, men named Bob are expected to ________.

A.wear glasses B.have big eyes C.look beautiful D.have round faces

4.What do we know from this research?

A.Nicknames have a bigger influence on people's appearance.

B.Gender and race have no influence on a person's appearance.

C.The volunteers guessed nearly four names correctly out often.

D.People are good at recognizing the different characteristics of faces.

九年级英语阅读单选简单题查看答案及解析

Today we can do everything with apps: pay bills, order food and shop for anything. Mobile technology means we can hold the world in our hands. However, when it comes to technology and health care, opportunities and challenges come together.

Let’s start with the ways to get health care. Telemedicine can allow a patient to use technology to see the doctor online and get a diagnosis (诊断) and instructions without leaving home.

In addition, there are many patient websites. These allow for different kinds of interactions about our health needs without involving the medical team. Setting a date with doctors and reading lab results are readily achieved by technology.

A whole new age of medical care seems likely (可能的) to come in the future. But every coin has two sides. What might be on the other side of techno-health care?

Firstly, we should think about the health care experience as a whole. A usual visit to a doctor begins with a receptionist (接待员) , who can see and tell how a patient is doing, This may influence the treatment effect. It’s unlikely that a patient website will have such intuition.

Next, sharing the details of one's life requires trust, which takes time to build. This is certainly true in health care, where some of life's best and worst moments involve doctors. The human touch should not be undervalued and is unlikely to be there over the smartphone.

Lastly, test results can be difficult to understand. When someone without a medical degree sees a flagged result with no explanation on the website, there's room for all kinds of stories to form in their minds—and also great worry.

So how does medicine adapt (适应) to the new technology age? Very talented companies are working on it .There is medical equipment(设备) that can be used at home to send necessary signs and heart sounds through telemedicine . It seems likely that some companies will find a way to explain test results.

But what it will not achieve is the warmth of human interaction and touch. Patients often need someone to listen to —and care about—their journey story, which will never be realized through a human-less technology. Technology should be a tool, but depending on it totally will most certainly have unexpected effects. Let's not allow our humanity to be one of them.

1.According to the passage, how does technology help health care?

A.It encourages doctors to voice their needs on the websites

B.It offers the patient a convenient way to get a diagnosis

C.It improves relations between doctors and patients.

D.It provides an opportunity to build a medical team

2.The word “intuition” in Paragraph 5 probably means______.

A.an ability to understand B.an interesting experience

C.a chance to win D.a fair decision

3.What do you know about techno-health care from the passage?

A.Patient websites require trust from doctors.

B.Talented companies can give medical advice.

C.Flagged results may cause worry for patients.

D.Medical equipment collects patients’ stories.

4.The writer probably agrees that_____.

A.technology can deal with unexpected effects.

B.telemedicine can take the place of usual health care.

C.it is difficult for patients to adapt to the new technology age.

D.techno-health care should take humanity into consideration.
