It’s parents’ worst nightmare. Their child doesn’t come home one evening and is missing for several days.
When a 14-year-old boy from Atlanta, Georgia disappeared earlier this year, his mother turned to her Smartphone for clues using an app（应用程序） called Family Tracker that helped track his location.
“You can see where your loved ones are without having to call or bother them. ”said Roberto Franceschetti of LogSat, the creators of the Family Tracker, which has more than 100,000 users and is available worldwide.
Parents can track the location of their child on a map, send messages, and even sound an alarm on the phone in a long distance.
“We have an option for the sender to make a very unpleasant, noisy sound. It’s a loud alarm and we repeat that sound every two minutes until the person picks it up, ”he said.
Parents don’t need to own a Smartphone to track their children. The service is also accessible through the web, as long as the phone that is being tracked is running the app.
Family Tracker has an additional service that keeps records of all data from the app for a two-week period, which the company calls GPS breadcrumbs.
“With a subscription（预定）, we keep all the locations where people have been on our servers. You can see where your kid has been for the past two weeks. You can find out where someone was at a certain time or when that person was at a specific place, ”Franceschetti explained.
“When somebody gets abducted（劫持）, usually whoever does this throws the phone away or takes the battery out. We were hoping that our app would at least provide information on where the person was abducted or where they had been in the past. ”
But will these types of apps let out personal secrets?
“The advantages are huge compared to the disadvantages. Let’s not forget that the person always has to give initial permission—no one can be tracked unless they allow someone to do it. ”said Franceschetti. According to the passage, all of the following about “Family Tracker” are true EXCEPT that __________.
| A．it can help parents know where their children are |
| B．all parents don’t need to own a Smartphone to track children |
| C．parents can use all the services of the app for free |
| D．it has little to do with letting out personal secrets |
What can we infer from the passage?
| A．The app will enjoy a great popularity in the future. |
| B．The loss of children won’t be a nightmare for parents any more. |
| C．The app will repeat the loud alarm continuously whenever parents track children. |
| D．The app can keep records of information for more than half a month. |
Which belong to the functions of the new app?
a. track location b. detect criminals c. send messages
d. protect privacy e. send remote alarm f. record information
| A．a, b, c, e | B．a, c, e, f | C．a, c, d, e | D．a, d, e, f |
For much of the world, vegetarianism (素食主义) is largely a matter of economics: Meat costs a lot more than beans or rice, so meat becomes a special-occasion dish. Even where meat is more plentiful, it’s still used in control, and it often provides a side note to a meal rather than taking center stage.
In countries like the United States where meat is not as expensive, though, people choose to be vegetarians for reasons other than cost. Parental preferences(父母亲的偏爱), religious or other beliefs, and health problems are among the most common reasons for choosing to be a vegetarian. Many people choose a vegetarian diet out of concern over animal rights or the environment. And lots of people have more than one reason for choosing vegetarianism.
Different people follow different forms of vegetarianism. A true vegetarian eats no meat at all, including chicken and fish. A lactoovo(乳制品) vegetarian eats dairy products and eggs, but keeps out meat, fish, and chicken. It follows, then, that a lacto(乳，乳汁) vegetarian eats dairy products but not eggs, and an ovo （蛋，鸡蛋） vegetarian eats eggs but not dairy products.
A stricter form of vegetarianism is veganism. Not only are eggs and dairy products excluded (排除) from a vegan diet, so are animal products like honey. Some macrobiotic (养生的) diets fall into the vegan category. Macrobiotic diets limit not only animal products but also refined（经过提炼的） and processed foods, foods with preservatives, and foods that contain caffeine or other stimulants (刺激物).
Following a macrobiotic or vegan diet could lead to nutritional deficiencies (营养不足) 
in some people. Teens need to be sure their diets include enough nutrients to fuel growth, particularly protein and calcium (钙). If you’re interested in following a vegan or macrobiotic diet it’s a good idea to talk to a registered dietitian（营养学家）. He or she can help you design meal plans that include enough nutrients.

Satellites are an important part of our ordinary lives．For example, the information for weather forecasts is sent by satellite．Some satellites have cameras which take photographs of the Earth to show how clouds are moving．Satellites are also used to connect our international phone calls．
Computer connections of the World Wide Web and Internet also
use satellites. Many of our TV programs come to US through satellites．Airplane pilots also sometimes use a satellite to help them find their exact location．
We use satellites to send television pictures from one part of the world to another．They are usually 35，880 kilometers above the equator．Sometimes we can see a satellite in the sky and it seems to stay in the same place．This is because it is moving around the world at 11，000 kilometers an hour—exactly the same speed that the earth rotates．A satellite must orbit the Earth with its antennae(天线)facing the earth．Sometimes, it moves away from its orbit，So there are little rockets on it which are used to put the satellite back in the right position．This usually happens about every five or six days．
Space is not empty! Every week, more and more satellites are sent into space to orbit the Earth．A satellite usually works for about 10-12 years．Satellites which are broken are sometimes repaired by astronauts or sometimes brought back to Earth to be repaired．Often，very old or broken satellites are left in space to orbit the Earth for a very long time．This is very serious because some satellites use nuclear power and they can crash into each other．．Which of the following is NOT done by satellites according to the passage?
| A．Sending information for weather forecast． |
| B．Taking photographs of the Earth． |
| C．Sending TV pictures． |
| D．Providing food for airplane pilots． |
．What’s the speed the earth rotates at?
| A．35,880 kilometers per hour． | B．335,880 kilometers per hour． |
| C．11,000 kilometers per hour． | D．110,000 kilometers per hour |
．Why does the satellite move around the world at the same speed as the Earth rotates?
| A．In order to take photographs． |
| B．In order to stay in a certain position in the orbit． |
| C．In order to move away from its orbit． |
| D．In order to send television pictures． |
．What does the underlined word “This” in the 3rd paragraph refer to?
| A．A satellite． |
| B．A little rocket． |
| C．A satellite seems to stay in the same place in the sky． |
| D．The satellite puts the rockets in the right position． |
．Which is true of satellites?
| A．A satellite usually works for about 10-12 years． |
| B．Every time a satellite gets broken，it is brought back to the Earth to be repaired． |
| C．A broken satellite is never left in space． |
| D．They often crash into each other． |
As late as 1800, women’s only place was in the home. The idea of woman in the business world was unthinkable. Men were certain that no woman could do a good job outside her home. This was such a widely accepted idea that when the well-known Bronte sisters began writing books in 1864, they had to sign their books with men’s names instead.
Teaching was the first profession open to women soon after 1800. But even that was not an easy profession for women to enter because most schools and colleges were open only to men. Oberlin College in Ohio was the first college in America to accept women.
Hospital nursing became respectable work for women only after Nightingale became famous. Seeing that she was not only a nurse but also a rich and well-educated woman, people began to believe it was possible for women to nurse the sick and still be “ladies”. Miss Nightingale opened England’s first training school for nurse in 1860.
The invention of the typewriter in 1867 helped to bring women out of the home and into the business world. By 1900, thousands of women were working at real jobs in schools, hospitals and offices in both England and America. Some women even managed to become doctors or lawyers. The idea that women could work in the business world had been accepted. Why couldn’t women become teachers easily? Because___________

I first visited hutong as part of a tourist group several years ago. We rode on a trishaw（脚踏三轮车） with a guide explaining the history, architecture and lifestyle of the local inhabitants.
Having visited the "must-sees" of Beijing, like the Forbidden City, the Temple of Heaven, the Drum Tower and
the Summer Palace, going into the hutong home of some famous ancient families gave the “Beijing experience” a human element.
My curiosity has sharpened over the years from reading about them at every opportunity. During the preparation for the Olympics I was eager to learn that some siheyuan courtyards in hutong were turned into accommodations（食宿） for visitors. I wished to stay in one someday.
Preparing for a recent trip to the capital, I eagerly sought one out. On my limited teacher’s salary, I settled on an affordable option, though I looked longingly at the more upscale courtyard accommodations.
As usual, I ended up having something closer to a true experience. A real family still lives in the courtyard, which is closer to the original. The rooms all opened into the central courtyard. Flowers were blooming, beans and peas were climbing up the bamboo fence, and the cat was napping in the sun. Every day after exploring the city, I'd hurry back to the hutong, take a quick shower and join the cat – snoozing（小睡） in a bamboo-made chair with a book ready nearby.
As the other guests came back we’d greet one another. There was a mother and young daughter from France, a guy from Canada, a mother and teenage daughter from the Netherlands, a teacher from England and several guests from various parts of China.
Coming and going through the narrow alleys（小巷） of the hutong, the residents would smile and give cheery “ni hao” （hello）. Laughing children were playing under the watchful eyes of the neighbors. I felt right at home in this friendly neighborhood. The main idea of the passage is about ______________.
| A．hutong days realize my desires to live local life |
| B．Trishaw is the only way to visit the hutong |
| C．living in the hutong with other visitors |
| D．exploring the deeper of Beijing |
. When did the author have th
e idea to visit Beijing hutong?
| A．As early as he was a little child |
| B．when he was reading the text books at school |
| C．during the preparation for the Olympics |
| D．the author doesn’t mention it specifically |
The underlined word “upscale” in the fourth paragraph means _________.
| A．inexpensive | B．high-class | C．appropriate | D．secondary |
What is the impression of the author about the people in hutong?
| A．They came from all over the world. |
| B．They all wanted to enjoy the old life of Beijing. |
| C．They are living together in harmony. |
| D．They are living in a heavenly peace life. |
What makes a person a scientist? Does he have ways or tools of learning that are different from those of others? The answer is “no”. It isn’t the tools a scientist uses but how he uses these tools which make him a scientist. You will probably agree that knowing how to use a power is important to a carpenter. You will probably agree, too, that knowing how to investigation, how to discover information, is important to everyone. The scientist, however, goes one step further; he must be sure that he has a reasonable answer to his questions and that his answer he gets to many questions is into a large set of ideas about how the world works.
The scientist’s knowledge must be exact. There’s no room for half right or right just half the time. He must be as nearly right as the conditions permit. What works under one set of conditions at one tim
e must work under the same conditions at other times. If the conditions are different, any changes the scientist observes in a demonstration(实证) must be explained by the changes in the conditions. This is one reason why investigations are important in science. Albert Einstein, who developed the Theory of Relativity, arrived at the theory through mathematics. The accuracy(正确性) of his mathematics was later tested through investigation. Einstein’s
ideas were proved to be correct. A scientist uses
many to
ols for measurements. Then the measurements are used to make mathematical calculations(计算) that may test his investigations What makes a scientist according to the passage?
| A．The tools he uses. | B．His ways of learning |
| C．The way he uses his tools | D．The various tools he uses |
“…knowing how to investigation, how to discover information, is important to everyone.”
The writer says this to show ___________.
| A．the importance of information |
| B．the difference between scientists and ordinary people. |
| C．the importance of thinking |
| D．the difference between carpenters and ordinary people |
A sound scientific theory should be one that _________.
| A．works under one set of conditions at one time and also works under the same conditions at other times |
| B．doesn’t allow any change even under different conditions |
| C．Can be used many times under different conditions |
| D．Can be used for many purposes |
What is the main idea of the passage?
| A．Scientists are different from ordinary people. |
| B．The Theory of Relativity. |
| C．Exactness is the core (核心) of science. |
| D．Exactness and way of using tools are the keys to making of a scientist. |
