A new study gives us the warning that about thirty percent of the world's people may not have enough water by the year 2025.
A private American organization called Population Action International did the new study. It says more than three-hundred-thirty-five-million people lack enough water now. The people live in twenty-eight countries. Most of the countries are in Africa or the Middle East.
P-A-I researcher Robert Engelman says by the year 2025, about three-thousand-million people may lack water. At least 18 more countries are expected to have severe water problems. The demand for water keeps increasing. Yet the amount of water on Earth stays the same.
Mr. Engelman says the population in countries that lack water is growing faster than in other parts of the world. He says population growth in these countries will continue to increase.
The report says lack of water in the future may result in several problems. It may increase health problems. Lack of water often means drinking waters not safe. Mr. Engelman says there are problems all over the world because of diseases, such as cholera, which are carried in water. Lack of water may also result in more international conflict. Countries may have to compete for water in the future. Some countries now get sixty percent of their fresh water from other countries. This is true of Egypt, the Netherlands, Cambodia, Syria, Sudan, and Iraq. And the report says lack of water would affect the ability of developing to improve their economies. This is because new industries often need a large amount of water when they are beginning.
The Population Action International study gives several solutions to the water problem. One way, it says, is to find ways to use water for more than one purpose. Another way is to teach people to be careful not to waste water. A third way is to use less water of agriculture.
The report also says long-term solutions to the water problem must include controls on population growth. It says countries cannot provide clean water unless they slow population growth by limiting the number of children people have.__________ are expected to have severe water problems by the year 2025

No one wants to look silly or do the wrong thing at a new job. It’s important to make the right impression (印象) from the first day. You will face new people. You will be in a new place. It may be difficult to know what to do. Here are seven tips to help you make it through the first days at a new job:
1. First impression is important. Make sure you make a good one. Before your first day, find out if your new job has a dress code. If so, be sure to follow it. No matter what you wear, always be neat (整洁) and clean.
2. Get to work on time. Employers value workers who come to work on time. Give yourself an extra 15 minutes to make sure you arrive on time.
3. Pay attention to introduction. One of the first things that your supervisor (主管) may do is to introduce you to co-workers. These co-workers will be important to you. They are the ones who will answer your questions when the boss isn’t around.
4. Ask plenty of questions. Make sure that your supervisor has told you what your are expected to do. If he or she has not told you your job duties, ask for a list. Set daily and weekly goals for yourself.
5. Don't make personal phone calls. You should never make personal phone calls to your friends and family unless it's an emergency.
6. Don’t take too long for lunch. What’s the lunch-hour policy at your new job? You can find out from your supervisor or your company’s personnel department(人事部门). For example, do people eat at their desks or does everyone take a full hour outside the workplace?

Tourism wasn’t as important as it is today. In the past, only people with a good deal of money could travel on holidays to other countries. More people travel today than in the past because there is a growing middle class in many parts of the world; that is to say, people now have more money for travel. Special plane fares(费用) for tourists make travel less expensive and more attractive than ever before. One person doesn’t travel for the same reason as another. But most people enjoy seeing countries that are different from their own. They also like to meet new people and to taste new food.
Tourism causes many changes in a country and in people’s lives. People build new hotels and restaurants and train native men and women as guides to show visitors interesting places. There’re new nightclubs and other amusements. International tourism is clearly a big business.More people travel today than in the past because______________.

A well-dressed man entered a famous jewelry shop. He explained that he wished to buy a pearl for his wife’ s birthday. The price didn’t matter, since business had been very good for him that year. After examining a nice black one that costs $5, 000, he paid for the pearl in cash, shook hands with the jeweler, and left.
A few days later the man returned and said that his wife liked the pearl so much that she wanted another one just like it. It had to be exactly the same size and quality as she wanted a pair of earrings made. "Can you give me any advice on how to get such a pearl?" said the man. The jeweler regretfully replied, "I would say it’s exactly impossible to find one exactly like that pearl."
The rich man insisted that the jeweler advertise in the newspapers, offering $25,000 for the matching pearl. Many people answered the advertisement but nobody had a pearl that was just right.
Just when the jeweler had given up hope, a little old lady came into his store. To his great surprise, she pulled the perfect pearl from her purse." I don’t like to part with it." she said sadly, I got it from my mother, and ,my mother got it from hers. But I really need the money.

Tens of thousands of smartphone applications are running ads from the overwhelming(势不可挡的) advertising networks that change smartphone settings and copy people’s contact information without permission.
Aggressive ad networks can disguise（假扮） ads as text message notifications (通告), and sometimes change browser settings and bookmarks. Often, the ads will upload your contacts list to the ad network’s servers--- information that the ad network can then sell to marketers.
Sounds scary? It’s not a giant problem yet, but it’s a growing one. As many as 5% of free mobile apps use an “aggressive” ad network to make money, according to Lookout, a San Francisco-based mobile security company. PhoneLiving was one of the most popular app developers to use these kinds of ad networks; their dozens of talking animal apps have been downloaded several million times. Later, PhoneLiving says it has mended its ways. The company admittedusing invasive techniques to make money from its apps, but said it dropped those methods at the start of July because of bad reviews and declining downloads.
The most popular type of apps that use aggressive ad networks are “Personalisation” apps, which include wallpapers. Comic and entertainment apps are also among the most likely to have rogue(凶猛的) ad networks running behind the scenes. Like aggressive pop-ups on PCs, the bad software isn’t easy to get rid of. Though the damage can typically be removed by deleting the app, it can be hard to tell which app is causing the problems.
When developers create free mobile apps, they usually make money through ads displayed within the app. App makers don’t usually tell people which ad network they are using, which makes it hard to avoid the known offenders. The best defense is to read reviews and avoid downloading apps that have attracted many complaints.What is an example of bad behavior by the annoying mobile ads?
| A．They change browser settings and bookmarks. |
| B．They change people’s calendar settings. |
| C．They send scam text messages occasionally. |
| D．They download free versions of games. |
What do we know about PhoneLiving?
| A．Its operation model is against the will of netizens. |
| B．It was forced to admit its bad behavior. |
| C．It has changed its business model rapidly. |
| D．Its relationship with Lookout may break up. |
Why is the bad software hard to get rid of?
| A．The software runs behind the scenes. |
| B．The app is very hard to delete. |
| C．It is difficult to find the problem app. |
| D．The network antivirus is out of date. |
What does the underlined word, “ invasive”, mean in the third paragraph?
| A．innovative | B．positive | C．flexible | D．aggressive |
What is the main idea of the passage?
| A．Mobile ads can attack your phone and steal your contacts. |
| B．Mobile ads have become popular in recent years. |
| C．Smartphones have been damaged by mobile ads. |
| D．You may download some aggressive apps unconsciously. |
Have you heard of snake robots? Scientists and doctors are already using tiny snakes that coil through the human body armed with sharp surgical tools to perform operations on hearts, prostate cancer, and other diseased organs. The snake robots that carry tiny cameras, scissors and forceps, and even more advanced sensors are being developed.
The next generation of the robots will be wireless, and will explore inside your body on their own--- not attached to any cables. For now, they are powered by cables that humans control. Experts say the day is coming when some robots will roam around the body on their own. But the experts in robotics say the new creations work best when they are designed for very specific tasks.
Howie Choset has been researching and building robots, particularly snake robots. He believes that his snake robot and others like it can help reduce medical costs by making complex surgery faster and easier. Choset says his new design is smaller and more flexible than earlier models.
The size of surgical robots allows surgeons to operate with far less damage to the body, helping the patient heal faster. Choset has also built larger snake robots designed for search and rescue, or just exploration. They can climb poles and trees and then look around through a camera in the head and slither through places that humans cannot reach.
“ We sent our snake robots into these caves in the Red Sea to look for evidence of ancient Egyptian ships,” he said. “ To me, archeology is like search and rescue, but everyone has been dead for 5,000 years.”
The doctors are very excited about the potential for surgical robots to do things that humans can’t do. The variety of sensors available for surgical robots keeps expanding. As they get smaller, maybe one day they will be able to test chemicals or blood in the body, or even the electrical connections in nerves.What can we learn from the first paragraph?
| A．The doctors carry out surgery using snake robots mainly for heart disease. |
| B．The doctors are very satisfied with the new snake robots during surgery. |
| C．Snake robots are completely free of human control today. |
| D．Other supplementary appliances will be added to snake robots. |
Which of the following is true, according to the passage?
| A．Snake robots are only used in the medical field. |
| B．Snake robots can reduce the patients’ medical costs. |
| C．Scientists are uncertain about the prospects for snake robots. |
| D．Scientists are forced to spend a lot of time researching snake robots. |
How can snake robots work best, according to the passage?
| A．When they carry tiny cameras, scissors and forceps. |
| B．When they are operated by experienced doctors. |
| C．When they are given a wireless function. |
| D．When they are designed for particular tasks. |
Why do we know about Howie Choset, according to the passage?
| A．He thought snake robots of different sizes can be used for different types of surgery. |
| B．He thought patients’ pain had been slightly reduced with the help of snake robots. |
| C．He also made snake robots for search, rescue and exploration. |
| D．He is very interested in researching ancient Egyptian ships. |
