Mozilla has shown off a prototype(雏形) for a $25 (£15) smart phone that is aimed at the developing world.

The company, which is famed mostly for its Firefox browser(浏览器), has partnered with the Chinese low-cost chip maker Spreadtrum.

While not as powerful as more expensive models, the phone will run apps and make use of mobile internet.

It would appeal to the sorts of people who currently buy cheap “feature” phones, analysts said.

Feature phones are highly popular in the developing world as a halfway point between “dumb” phones --- just voice calls and other basic functions --- and fully-developed smart phones.

Mozilla hopes that it will take an early lead in a market that is now being targeted by mobile phone producers who see the developing world as the remaining area for massive growth.

It will face fierce competition from bigger, more popular brands, however --- with more announcements of this kind expected over the course of the next couple of days at the Mobile World Congress in Barcelona.

“These solutions expand the global accessibility of open web smart phones to first-time and entry-level smart phone buyers by reducing the time and cost required for handset makers to bring these phones to market,” said Spreadtrum in a press statement.

Mozilla said the phone “redefines”(重新定义) the entry-level phone market.

The concept of a cheap smart phone may seem likely to appeal to consumers in developed countries, particularly those who locked into long contracts in order to pay part of the cost of the likes of the Apple iPhone and Samsung Galaxy range.

But analyst Carolina Milanesi, from Kantar World panel, said it should not be seen as a competitor.

1.Which of the following is true about the $25 smart phone?

A. It has all the functions of an iPhone.

B. It is specially designed for the developed world.

C. It will attract the present “feature” phone users.

D. It is made by the Chinese low-cost chip maker Spreadtrum.

2.What is the feature of a “feature” phone?

A. Though cheap, it can completely replace the iPhone.

B. It is just used for voice calls and other basic functions.

C. It has nearly all the functions of a fully-developed smart phone.

D. Its functions are between those of a “dumb” phone and a fully-developed smart phone.

3.We can learn from the text that at the Mobile World Congress in Barcelona ________.

A. new cheap smart phones will beat high-end ones

B. the $25 smart phone coming from Mozilla will be the best seller

C. quite a few companies will announce their new cheap smart phones

D. Mozilla will be the only company to announce its new cheap smart phone

4.Which of the following held a negative attitude towards the cheap smart phone?

A. Mozilla.　　 B. Spreadtrum.

C. Samsung. D. Carolina Milanesi.

Recently a new US study has shown that couples who expect their children to help care for them in old age should hope they have daughters because they are likely to be twice as attentive overall.

The research by Angelina Grigoryeva, a sociologist at Princeton University, found that, while women provide as much care for their elderly parents as they can manage, men do as little as they can get away with and often leave it to female family members.

Using data from the University of Michigan Health and Retirement Study, a study which has been tracking a cross-section of over-50s for the last decade, she calculated that women provide an average of 12.3 hours a month of care for elderly parents while men offer only 5.6 hours.

“Whereas the amount of elderly parent care daughters provide is associated with limitations they face, such as employment or childcare, sons’ caregiving is connected only with the presence or absence of other helpers, such as sisters or a parent's spouse （配偶）,” she explained.

“Sons reduce their relative caregiving efforts when they have a sister, while daughters increase theirs when they have a brother.”

“This suggests that sons pass on parent caregiving responsibilities to their sisters.”

In the UK, the 2011 census （人口普查）showed that there are now around 6.5 million people with caring responsibilities — a figure which has risen by a tenth in a decade.

But many are doing so at the risk of their own health. The census showed that those who provide 50 hours or more of care a week while trying to hold down a full-time job are three times more likely to be struggling with ill health than their working counterparts （相对应的人）who are not careers.

1.What does the underlined phrase “is associated with” in Paragraph 4 mean?

A.is faced with B.is related to

C.is filled with D.is fond of

2.According to the study we know that　　 .

A.American couples are preferring daughters to sons a lot

B.sons are twice likely as daughters to care for parents in old age

C.having a brother makes women do their share less

D.men tend to take less care of their parents than women

3.Which of the following statements is true?

A.The number of people providing care has increased by 6.5 million.

B.More people have left behind their work to look after the elderly.

C.Many people who both work and care others can be threatened by health problems.

D.People shouldn't take much responsibility to care for the old.

4.What's the attitude of the author in the article?

A.Positive. B.Subjective.

C.Objective. D.Negative.

A recent study has shown that eating a small amount of dark chocolate every day could be good for your health. Scientists have found that a regular 2 ounces can help lower blood pressure and reduce the risk of having a heart attack or stroke（中风）without any weight gain. But take care before you reach for a large bar. The effects are canceled out if more than 30 calories are taken into your body each day, the researchers warn.

It’s already known that a chemical called polyphenol（多酚）, found in chocolate, can help reduce blood pressure, and blood pressure lowered in this way can reduce the risk of death from a stroke by 8 percent and from a heart attack by 5 percent, scientists declare. And it can also reduce the risk or death in general by 4 percent.

A daily diet with a little chocolate has the same effect with some special diets designed to lower blood pressure, according to one researcher. “Although all the degree of the blood pressure reduction is small, the effects are quite obvious,” the researchers said.

However, Sara Stanner, a nutritionist at the British Heart Foundation, is quite cautious. “This study suggests that small quantities of small chocolate might have good effects on blood pressure. However, it is important to remember that chocolate is also high in fat and calories. So eating much is not good for your heart.” “Polyphenols are also found in fruits and vegetables, which can be taken in without the risks associated with overintake,” she added.

But the German study shows that the fat content does not cancel out the good effects—at least where small amounts are concerned.

1.How is Paragraph 2 developed?

A. By making comparisons.　　　　 　　　 B. By listing figures.

C. By analyzing causes.　　　　　　　　 D. By giving examples.

2.What health benefits does dark chocolate have?

A. It lowers blood pressure heavily.

B. It may prevent heart attacks in a way.

C. It’s useful for controlling one’s weight.

D. It helps people strengthen their body.

3.What do Sara Stanner’s words suggest?

A. Eating chocolate has no health benefits.

B. Dark chocolate is not so nutritious as expected.

C. The findings of scientist’s study are not scientific.

D. Eating fruits and vegetables may be a better choice.

4.What will be discussed in the following passage?

A. Some details of the German study.

B. Benefits of fruits and vegetables.

C. Harm of overeating dark chocolate.

D. The proper amount of dark chocolate taken in.

高二英语单项填空简单题查看答案及解析

Speeding off in a stolen car, the thief thinks he has got a great catch. But he is in for an unwelcome surprise. The car is fitted with a remote immobilizer (发动机防盗系统), and a radio signal from a control centre miles away will ensure that once the thief switches the engine off, he will not be able to start it again.

The idea goes like this. A control box fitted to the car contains a mini-cellphone, a micro-processor and memory, and a GPS satellite positioning receiver. If the car is stolen, a coded cellphone signal will tell the control centre to block the vehicle’s engine management system and prevent the engine being restarted.

In the UK, a set of technical fixes is already making life harder for car thieves. “The pattern of vehicle crime has changed,” says Martyn Randall, a security expert. He says it would only take him a few minutes to teach a person how to steal a car, using a bare minimum of tools, but only if the car is more than ten years old. Modern cars are far tougher to steal, as their engine management computer won’t allow them to start unless they receive a unique ID code beamed out by the ignition key (汽车等的点火开关).

In the UK, technologies like this have helped achieve a 31% drop in vehicle-related crime since 1997. But determined criminals are still managing to find other ways to steal cars, often by getting hold of the owner’s keys .And key theft is responsible for 40% of the thefts of vehicles fitted with a tracking system. If the car travels 100 metres without the driver confirming their ID, the system will send a signal to an operations centre that it has been stolen. The hundred metres minimum avoids false alarms due to inaccuracies in the GPS signal. Staff at the centre will then contact the owner to confirm that the car really is missing, and keep police informed of the vehicle’s movements via the car’s GPS unit.

1.What’s the function of the remote immobilizer fitted to a car?

A. To allow the car to lock automatically when stolen

B. To prevent the car thief from restarting it once it stops

C. To help the police make a surprise attack on the car thief

D. To prevent car theft by sending a radio signal to the car owner

2.By saying “The pattern of vehicle crime has changed” (Lines1-2,Para.3) Martyn Randall suggests that _____.

A. Self-prepared tools are no longer enough for car theft

B. the thief has to make use of computer technology

C. it takes a longer time for the car thief to do the stealing

D. the thief has lost interest in stealing cars over 10 years old

3.What is essential in making a modern car tougher to steal?

A. A GPS satellite positioning receiver

B. A unique ID card

C. A special cellphone

D. A code ignition key

4.Why does the tracking system set a 100-metre minimum before sending an alarm to the operations centre?

A. To give the driver time to contact the operation centre

B. To allow for possible errors in the GPS system

C. To keep police informed of the car’s movements

D. To leave time for the operations centre to give an alarm

So you have been called for an interview－well done. Your effort has paid off. Now go to get the job. You will feel better at the interview if you show an understanding of the nature of the organization.

Ask someone who already does it or check it out with one of the advisers.

Ask a member of family or a friend to act as the employer and to give you a practice interview. Afterwards discuss how it went.

Think about how the employer would prefer to see your look. Remember most of the employers are over 30. It is not wise to buy new clothes that will be worn for the first time at the interview. It’s best to wear a familiar dress.

Carelessness in any of these could cost you the job. Arrive at least 15 minutes ahead of time. This will give you a chance to have a look around，read the notice board and get the feel of the place. Being late at interviews produces a bad impression. The first impression the interviewer gets of you is formed as you walk through the door，so take a couple of deep breaths.

Be ready to shake hands if the interviewer offers.

Don’t take a seat until asked. Then sit comfortably.

Remember the interviewer’s name and use it from time to time.

Be ready for the question “Is there anything you want to ask？” Before the interview you should get ready for two or three such questions. Look on these not just as a chance to get information but as a means to leave a better impression. Asking can show knowledge and avoid asking about holidays， pension (养老金) and so on. You can check on these later when the hoped­for job is offered.

And if you fail，look upon the interview as an experience in itself. Learn from it.

We wish you good luck and good job hunting.

1.To make a good impression on the interviewer, it is important for you __________.

An experimental treatment that causes AIDS patients to develop a dangerously high fever has shown promise as a way of prolonging and improving the patients’ life.Called the Biologic-HT System, the new treatment lets doctors extract the blood of a patient and heat it before circulating it back into the body. The heated blood causes the patient’s body temperature to rise above 42 degrees Celsius. In people with AIDS, that increase in temperature kills some heat-sensitive HIV, the virus, most doctors say, causes AIDS.

Heating the blood of AIDS patients has been tried before, say doctors. But during previous attempts, the treatment induced deadly chemical changes in the blood. The Biologic-HT System prevents those changes from happening, allowing the heat to kill viruses with few ill side effects.

The new heat treatment cannot be considered a cure for Aids, says president of the company that makes the system. He says the treatment doesn’t kill all traces of the virus. However, it kills enough virus particles to give a patient’s immune system a reprieve in its deadly duel with HIV.

Tests of the Biologic-HT treatment began on 36 patients earlier this year. The treatment takes about four hours, and the patient normally feels well enough to leave the hospital or clinic the following morning.

So far, the patients who have had the treatment say they feel better and have developed no new opportunistic infections—disease that strike people with damaged immune systems. The patients also have experienced about a 50 percent increase in the number of T cells in their bodies. T cells are key disease-fighting cells of the immune system and the main target of HIV.

1.This passage is mainly concerned with ____________.

A． a way for treating AIDS

B． a heat-sensitive virus

C． the immune system of the human body

D． the function of high temperature

2.The blood of the patient___________.

A． is heated with a single injection

B． is heated by being circulated at a higher rate

C． is taken out from the body and then circulated through a heating system.

D．is taken out from the body, heated outside and then put back into the body.

3.The previous attempts to use high temperature for treating AIDS failed because they_________.

A．caused chemical changes

B．could not kill HIV effectively

C．resulted in deaths

D．killed both HIV and healthy cells

4.According to the passage, the new treatment___________.

A．can kill all the HIV viruses

B．cannot eliminate the viruses completely

C． can double the number of disease-fighting cells

D．can reconstruct the patient’s immune system.

5.The result of the experiment seems to be ___________.

A．disappointing      B．incomplete        C．successful         D．surprising
