Aromatherapy(芳香疗法)
1.Aromatherapy is a form of alternative medicine which is based on the use of very concentrated essential oils from the flowers,leaves,bark,branches or roots of plants which are considered tohave healing properties.In aromatherapy these powerful oils are mixed with other oils,such as almond(杏仁)oil,or the are diluted(稀释)with water.These solutions(溶液剂)can be rubbed on the skin,sprayed in the air,or applied as a compress(敷药).
2.Many people have aromatherapy massages(按摩),and depending on the treatment a person is having,the aromatherapist will massage the oil into the hands or shoulders.The massage is smooth and flowing,as it is designed to create a sense of relaxation and calm.The sessions are tailored to the individual's health and mood at the time,so every session is unique.
3.Practitioners of aromatherapy believe that the aroma of the essential oils directly stimulates the brain or that the oils are absorbed through the skin into the bloodstream,where they can affect the whole body and promote healing.Other claims in support of aromatherapy are that it aids digestion,improves the functions of respiratory system,reduces muscular aches and pains,and promotes muscle relaxation and tone.It has also been argued that aromatherapy can improve circulation,lower blood pressure,and help combat insomia (失眠)and other stress-related disorders such as tension headaches , anxiety , and mild depression.
4.However,while aromatherapy may have real effects that promote a sense of well-being,some traditional medicine practitioners remain doubtful about its powers.While research has confirmed that aromatherapy does have some positive short-term effects on most people,it also suggests that aromatherapy is not an actual science or medicine that should be used to treat illness.Furthermore,not all aromatherapy is considered beneficial to health.There are precautions which should be taken before having aromatherapy because some oils can have negative effects on people with certain medical conditions.The study of aroma-therapy is relatively new and unexplored.More research needs to be conducted to make scientific conclusions about its use and effects.

The uses and benefits of aromatherapy need to_____.
A:suit different people
B:be further explored
C:help the disabled
D:be used externally
E:have healing effects
F:be promoted

答案:B
解析:

文章第四段从不同方面指出了芳香疗法对人体可能会产生的负面影响,故选E。
由文章第一段中的内容可知,芳香疗法主要使用由从植物的花、叶,皮、枝以及根茎中提取的精华油制成的溶液剂,这些溶液剂可以直接擦在皮肤上,喷洒于空气中,也可以作外敷药用。因此本题选D。
由文章第二段最后一句“The sessions are tailored to the individual's health and mood atthe time,so every session is unique.”可知,本题选A。
由文章第三段所描述的内容可知,一些人认为芳香疗法对人体具有多种功效。故本题选E。

第6题:

Recent research had claimed that an excess of positive ions (离子) in the air can have an ill-effect on people's physical or psychological health. What are positive ions? Well, the air is full of ions, electrically charged particles, and generally there is a rough balance between the positive and the negative charges. But sometimes this balance becomes disturbed and a larger proportion of positive ions are found. This happens naturally before thunderstorms, earthquakes or when winds are blowing in certain countries. Or it can be caused by a build-up of static electricity indoors from carpets or clothing made of man-made fibers, or from TV sets, duplicators or computer display screens.

When a large number of positive ions are present in the air many people experience unpleasant effects such as headaches, fatigue, irritability, and some particularly sensitive people suffer nausea (恶心) or even mental disturbance. Animals are also found to be affected, particularly before earthquakes; snakes have been observed to come out of hibernation(冬眠), rats to flee from their burrows, dogs howl and cats jump about unaccountably. This has led the US Geographical Survey to fund a network of volunteers to watch animals in all effort to foresee such disasters before they hit vulnerable areas such as California.

Conversely, when large numbers of negative ions are present, then people have a feeling of well-being. Natural conditions that produce these large amounts are near the sea, close to waterfalls or fountains, or in any place where water is sprayed, or forms a spray. This probably accounts for the beneficial effect of a holiday by the sea, or in the mountains with tumbling streams or waterfalls.

To increase the supply of negative ions indoors, some scientists recommend the use of ionizers : small portable machines which generate negative ions. They claim that ionizers not only clean and refresh the air but also improve the health of people sensitive to excess positive ions. Of course, there are the detractors, other scientists, who dismiss such claims and are skeptical about negative/positive ion research. Therefore people can only make up their own minds by observing the effects on themselves, or on others, of a negative rich or poor environment.

After all, it is debatable whether depending on seismic readings to anticipate earthquakes is more effective than watching the cat.

According to the passage, static electricity can be caused by

A.using home-made electrical goods.

B.wearing clothes made of natural materials.

C.walking on artificial floor coverings.

D.copying TV programs on a computer.


正确答案:C
解析:由题干static electricity定位在首段末句,用人造纤维做成的地毯或衣物可能产生静电。man—made“人造的”相当于artificial。故C为答案。文中仅提到电视机、复印机和电脑显示屏会产生静电,而A说法太笼统了,所以不选。

第10题:

Text 2 Britain's flexible labour market was a boon during the economic slump,helping keep joblessness down and then,when the recovery began,allowing employment to rise.Yet one of its bendier bits is causing politicians to fret.Ed Miliband,the leader of the Labour Party,has promised a crackdown on"zero_hours contracts"if he wins the next election.The government has launched a consultation.Zero-hours contracts allow firms to employ workers for as few or as many hours as they need,with no prior notice.In theory,at least,people can refuse work.Fully l.4m jobs were based on these contracts in January 2014,according to a snapshot taken by the Office for National Statistics.That is just 4%of the total,but the share rises to a quarter in the hospitality business.The contracts are useful for firms with erratic pattems of demand,such as hotels and restaurants.They have also helped firms to expand during the recovery-allowing them to test new business lines before hiring permanent staff,who would be more costly to make redundant if things went wrong.Flexibility suits some workers,too.According to'one survey,47%of those employed on zero-hours contracts were content to have no minimum contracted hours.Many of these workers are in full-time education.The ability to tum down work is important to students,who want to revise(or sit in the sun)at this time of year.Pensioners keen for a little extra income can often live with the uncertainty of not having guaranteed hours.Yet that leaves more than a quarter of workers on zero-hours contracts who say they are unhappy with their conditions.Some of this is cyclical.During recessions,a dearth of permanent positions forces people into jobs with no contracted hours even if they do not want them(the govemment has just said that unemployed people who refuse to accept zero-hours contracts could be cut off from benerits).Underemployment is particularly prevalent among these workers,35%of whom would like more hours compared with 12%in other jobs.As the economy recovers,many should be able to renegotiate their contracts or find permanent jobs.But the recovery will not cause unwanted zero hours contracts to disappear.Some workers will never have much negotiating power:they are constrained by geography,family commitments and lack of competition for their skills among a small number of big employers.Zero-hours contracts make it easier for employers to abuse their labour-market power.Some use them to avoid statutory obligations such as sick and maternity pay.Workers are penalised for not being available when requested.And some contracts contain exclusivity clauses which prevent workers from taking additionaljobs.These can harm other employers as well as workers,and actually reduce labour market flexibility.That,at least,is worth doing away with.
Which ofthe following is the best title ofthis text?

A.Zero-hours Contract-Lack of Flexibility
B.Zero-hours Contract-an Out-of-date Policy
C.Zero-hours Contract-an Illegal Policy
D.Zero-hours Contract-a Challenging Way Against Permanent Job

答案:A
解析:
主旨大意题。解决该题目的关键是,通过做完前四道题大体知道文章的中心,再次通读各段首句,验证中心。整个文章都是在围绕着零时工合同的影响来说,在结尾处明确地说明了零时工合同并不灵活,而与这个信息相对应的选项为A项Zero-hours Contract-Lack of Flexibility(零时工合同——缺乏灵活性),所以A项为正确选项。【干扰排除】剩余的选项分别为零时工合同过时、非法、挑战固定工作,这些信息在个别段落虽然有提及,但是不足以说明文章的中心,属于以偏概全,故均可排除。
