   Smoking is harmful. But as soon as you quit the habit, everything will be OK, right? Wrong.

New research has found that even if you give up smoking, the damage it has done to your genes will stay there for a much longer time. In the research, a team of US scientists studied the blood of 16,000 people. Among them, some were smokers, some used to smoke, and the rest were non-smokers. Scientists compared their genes and found that more than 7,000 genes of smokers had changed--a number that is one-third of known human genes.

According to NBC News, both heart disease and cancer are caused by genetic changes. Some people may have had the changes when they were born, but most people get them in their day-to-day lives while doing things like smoking.

When you stop smoking, a lot of these genes will return to normal within five years.

This means your body is trying to heal (治愈) itself of the harmful effects of smoking. But the changes in some of the genes stay for longer. They can stay for as long as 30 years, It’s almost like leaving a footprint on wet cement (水泥)----it will always be there, even when you’ve walked away and when the cement becomes dry.

Although the study results may make people unhappy, there is a bright side: the findings could help scientists invent medicine to treat genetic damage caused by smoking or find ways to tell which people have heart disease or cancer risks.

Disadvantages of the Cell Phone

There is more than one advantage and disadvantage of cell phones. Anyone considering purchasing their first cell phone, or considering getting rid of their cell phone, should look at the device from different angles. Surely there are disadvantages of buying cell phones. 【小题1】.

Added Costs

【小题2】. First, you will have to purchase a cell phone. While you may find a free phone option with your new wireless plan, smartphone devices can cost as much as $400 or more. Then you will have to pay a monthly fee for service. Service plans vary and can include costs for minutes, text messages, data, and insurance.

【小题3】.

Every time you have your cell phone with you, it could ring and interrupt what you are doing. While it is convenient to keep your phone with you when you are away from home, it also leaves you open to calls from your mother, your boss, or anyone that knows your phone number. This may lead some people to feel like they have less privacy than before.

Less Reliable than a Landline Telephone

【小题4】. This means a cell phone,' no matter how reliable, is not going to work everywhere unlike a landline telephone, which provides service that is more reliable.

Higher Possibility of Accidents

If you are talking or texting on your cell phone while you are driving, you are far more likely to be involved in a car accident. 【小题5】. And despite several recently imposed (强制实行的) laws banning cell phone use while people are driving, many find them almost impossible to carry out.

C.Cell phones cost money

   So let’s say that you’re sitting at a restaurant and when your food arrives, you take one bite and decide that something is preventing you from taking a second bite. No matter what the reason is, this dish is going back to the kitchen, and now it’s up to you to find a way to send it back politely.

First of all, the single most important thing to do when you’re sending something back is to do it immediately. If you eat half the dish before sending it back, the server and kitchen will believe that you really don’t need to send it back.

If a dish is too salty that it cannot be eaten, you should first let the server know what the situation is, and they’ll take it back to the kitchen and bring you a new one. Remember that it is not the server’s fault, so don’t take it out on them. Also, don’t be afraid that they’ll get angry at you, or someone will spit (吐) in your food. It’s their job to make sure that you’re satisfied, and if the kitchen clearly makes a mistake the server will be frustrated with the kitchen, not with the diner who has been served an inedible meal. A new dish will be cooked, and nobody’s going to spit in it.

There is, however, one example when you are sending back a dish which will really annoy both the server and the kitchen. If you order a pasta dish that contains pancetta but then send it back to the kitchen because you’re a vegetarian (素食者) and don’t know what pancetta is, and then congratulations because you’re one of the most unbearable types of customers a restaurant can have. A perfectly good plate of food is just thrown out because you don’t ask what pancetta is before ordering.

So the bottom line: Use common sense if you think that you need to send your dish back. If the kitchen do something wrong, then they’re on the hook for a new plate of food. If you do something wrong, then hopefully you’ve learned a lesson.

【小题1】When the diners find something wrong with the dishes they ordered, they should __________ .
A.send them back immediatelyB.eat half the dishes before sending them back
C.go back to the kitchen themselvesD.wait until the cook apologizes to them
【小题2】The underlined word “inedible” in Paragraph 3 can be replaced by “ __________”.
A.unbearableB.unpleasant
C.tastelessD.uneatable
【小题3】What will happen when you are sending back a dish owing to your own mistake?
A.You’ll be fined by the restaurant.
B.Your request will be refused immediately.
C.You’ll be forced to leave the restaurant.
D.Your food will be thrown out of the restaurant.
【小题4】The passage is intended to __________.
A.guide diners how to enjoy a good meal in a restaurant
B.introduce the best way to send back food in a restaurant
C.introduce the bottom line people should have in a restaurant
D.inform the diners of the most important things to do in a restaurant

阅读下面短文,根据所给情节进行续写,使之构成一个完整的故事。

Ariana caught another whiff(难闻的味道) and tried to hold her breath. She moved away slightly, but Ashley only moved closer and continued talking. Ariana felt trapped. She wanted badly to tell Ashley that she didn't smell very good. But how could she do that without hurting her feelings? Instead, she gathered the remains of her lunch to throw in the trash, thankful for the excuse to get some fresh air. She looked back to see Ashley eating quietly. Ashley's hair was tangled(乱糟糟的) , and her clothes were dirty. Ariana forced herself to go back to the table and take her seat, vowing(发誓) that she would not sit with Ashley tomorrow.

When Ariana got home from school, she complained to her mother, ''There's a girl named Ashley who likes to sit next to me in school, but she smells bad. ''

''She's probably having a tough day, '' said her mother.

''No, it's not just one day. She smells bad a lot, '' Ariana explained. ''Nobody else likes to sit next to her, either. ''

''I don't think you understand Ashley's situation, so let me ask you this..., '' Her mother's tone was serious. ''Who makes sure that your hair is combed every morning so you'll look nice when you go to school? ''

''You do, '' answered Ariana.

''Who makes sure you're bathed and cleaned every day? And your clothes are washed and neatly ironed? ''

''You and Daddy, '' Ariana said again.

''Do you live in a nice home? Do you have enough to eat? ''

Ariana nodded, beginning to feel guilty. She was starting to understand now. Ashley couldn’t help her situation because she was only seven years old—the same age as Ariana. Grown-ups are supposed to take care of kids.

''Why doesn't her family take better care of her? '' Ariana asked.

''Not all children live in the best situation, '' her mother said. ''The best thing you can do for Ashley is to treat her with kindness and sympathy. ''
