House Sitting

In many countries of the world people do what is called house sitting.It means that if owners of the house are going away, they want someone to come into their home and look after the house and maybe pets while they are away.

In Australia, many people travel.After people retire, they might buy a van and travel all over the country.1.

So if someone wants to travel or go away for some reason, they might want someone in their home to care for it and keep the gardens tidy.House sitters might have to care for pets.Also, quite a few people have swimming pools in their back yard and they need cleaning.2. I feel it is a great way of seeing the country, because you go and stay in a new city, get to meet new people, and have time to go sightseeing in a new area.

Some house sitting jobs are just for a few days or a couple of weeks while the house owner have a short holiday.Sometimes it is for much longer.We have had one house sit for six months, while the home owner travelled to Europe.

5. Then you can travel to many different countries and stay there.One of the important things to get are references from the home owners where you have stayed.A reference is a written letter to say that you are trustworthy and have looked after their home well.You can show these letters to prospective house sitting jobs and they know you will do a good job.

Picking a university is a tense period of asking yourself which institution is most relevant. That’s why university rankings play such a vital role in students searching for their next academic direction. Rankings are also an inescapable part of the reputation and brand image of universities. “No university website is complete without the claim to be in the top 100 for something or other,” reported the BBC. The reason is simple: Rankings help them to attract students, staff and research investment.

Currently there are numbers of university rankings, and each has its own list of criteria. But the main categories are the same: academic reputation, graduates' performance and faculty resources.

However, experts point out the ranking process isn't entirely reliable. Mark Kantrowitz, a US financial aid researcher, said university rankings were mostly just for show. He wrote in The New York Times. “It may give your parents better bragging rights, but that's about it.”

Moreover, it’s not difficult to see the limitations of university rankings. Many rankings focus on the number of times research work is cited (引用) by other researchers. It helps British and US universities to dominate global rankings because English is the favored language of academia, John O’Leary, a member of the QS academic advisory board, told The Gunrdian. Also, rankings such as QS mainly focus on the qualities of the university rather than its students. “Any university ranking is likely to help students make better decisions about where to study, but the need to balance them with other more human factors is also important,” said Phil Moss, an education and admissions consultant. “Advice from graduates or current students can be as valuable in providing a genuine insight into the experience or quality of a particular degree program. It can also add an element that rankings can never convey -- the actual emotion of a university experience.”

1.Why do universities consider rankings important?

A. Rankings make them more appealing.

B. Rankings are students’ only reference.

C. Rankings can increase their academic level.

D. Rankings help them complete their websites.

2.What does the underlined “It” in paragraph 4 refer to?

A. Academic research work.

B. The number of researches.

C. The way of ranking universities.

D. The limitation of university ranking.

3.According to John O’Leary, what helps British and US universities rank well?

A. The wide use of English in academia.

B. Their outstanding qualities.

C. Their graduates’ excellent performance.

D. The academia’s favor to them.

4.Besides ranking, what does Phil Moss suggest you should refer to if you're picking a university?

A. Investment in education.

B. Guidance from professors.

C. Information on websites.

D. Suggestions from students.

A glass a day keeps obesity at bay.Alcohol has always been thought to cause weight gain because of its high sugar content, but new research suggests a glass a day could form part of a diet.Looking at past studies they found that, while heavy drinkers do put on weight, those who drink in moderation can actually lose weight.

A spokesman for the research team at Navarro University in Spain says, “Light to moderate alcohol intake, especially of wine, may be more likely to protect against, rather than promote, weight gain”.The International Scientific Forum on Alcohol Research reviewed the findings and agreed with most of the conclusions, particularly that current data do not clearly indicate if moderate drinking increases weight.

Boston University’s Dr.Harvey Finkel found that the biologic mechanisms (生物学机制) relating alcohol to changes in body weight are not properly understood.His team pointed out the strong protective effects of moderate drinking on the risk of getting conditions like diabetes(糖尿病),which relate to increasing obesity.Some studies suggest that even very obese people may be at lower risk of diabetes if they are moderate drinkers.

The group says alcohol provides calories that are quickly absorbed into the body and are not stored in fat, and that this process could explain the differences in its effects from those of other foods.They agree that future research should be directed towards assessing the roles of different types of alcoholic drinks, taking into consideration drinking patterns and including the past tendency of participants to gain weight.

For now there is little evidence that consuming small to moderate amounts of alcohol on a regular basis increases one’s risk of becoming obese.What’s more, a study three years ago suggested that reveratrol, a compound present in grapes and red wine, destroys fat cells.

1.The passage is mainly for those ______.

A.who produce wine

B.who are eager to lose weight

C.who go on a diet

D.who have a drinking habit

2.The underlined phrase “in moderation” in the first paragraph means ______.

A.properly B.carefully

C.excitedly D.frequently

3.Why has alcohol been thought to cause weight gain?

A.Because its calories are stored in fat.

B.Because it is rich in sugar.

C.Because it changes drinking patterns.

D.Because it increases the risk of diabetes.

4.What can we learn from the passage?

A.The specific roles of different types of alcoholic drinks are very clear.

B.Resveratrol is proved to increase the risk of becoming fat.

C.The research found moderate drinking has a strong protective effect.

D.Current data clearly show that moderate drinking increases weight.

5.What is most likely to be discussed in the paragraph that follows?

A.How to do some easy experiments.

B.How to prove the finding mentioned above.

C.How to make wine in a healthy way.

D.How to reduce the calories contained in wine.

For the first time, researchers have discovered that some plants can kill insects in order to get additional nutrients. New research shows that they catch and kill small insects with their own sticky hairs near the roots and then absorb nutrients through their roots when the insects are killed and fall to the ground.

Professor Mark Chase, of Kew and Queen Mary, University of London, said: “The cultivated (改良的) tomatoes and potatoes still have the hairs. Tomatoes in particular are covered with these sticky hairs. They do trap small insects on a regular basis. They do kill insects.”

The number of these carnivorous plants is thought to have came up to 50 percent and many of them have until now been wrongly regarded as among the most harmless plants. Among them are species of petunia(矮牵牛), some special tobacco plants and cabbages, some varieties of potatoes and tomatoes, etc. Researchers at Royal Botanical Gardens Kew, which carried out the study, now believe there are hundreds more killer plants than previously realized.

It is thought that the technique was developed in the wild to get necessary nutrients in poor quality soil – and even various plants grown in your vegetable garden still have the ability.

The researchers, publishing their finding in the Botanical Journal of the Linnean Society, said: “We may be surrounded by many more murderous plants than we think.” “We are accustomed to thinking of plants as being immobile and harmless, and there is something deeply frightening about the thought of meat-eating plants," they added.

1.Tomatoes and potatoes kill insects to _____.

A. get more sticky hairs

B. make themselves grow better
