Europeans should try to stay indoors if ash from Iceland's volcano starts settling, the World Health Organization warned Friday as small amounts fell in Iceland, Scotland and Norway.
WHO spokesman Daniel Epstein said the microscopic(微小的) ash is potentially dangerous for people when it starts to reach the Earth because inhaled(吸入) particles can enter the lungs and cause respiratory problems. And he also said Europeans who go outside might want to consider wearing a mask.
Other experts, however, weren't convinced the volcanic ash would have a major effect on peoples' health and said WHO's warnings were "hysterical." They said volcanic ash was much less dangerous than cigarette smoke or pollution. Volcanic ash is made of fine particles of fragmented volcanic rock. It is light gray to black and can be as fine as talcum powder. During a volcanic eruption, the ash can be breathed deep into the lungs and cause irritation even in healthy people. But once it falls from a greater distance — like from the cloud currently hovering above Europe — its health effects are often minimal, experts say.
"Not all particles are created equal," said Ken Donaldson, a professor of respiratory toxicology at the University of Edinburgh, "In the great scheme of things, volcanic ash is not all that harmful." And he said most Europeans' exposure to volcanic ash would be negligible and that only those in the near districts of the Icelandic volcano would likely be at risk.
Dr. Stephen Spiro, a professor of respiratory medicine and deputy chair of the British Lung Foundation, said the further the particles travel, the less dangerous they will be. "The cloud has already passed over northern Scotland and we haven't heard of any ill effects there," he said. Spiro said to wear masks or stay indoors to avoid volcanic ash was "over the top" and "a bit hysterical."
1. The text is mainly about         .
A. the effect of volcanic ash

2. Which one is true according to Paragraph3?

B. The ash caused irritation even in healthy people.
C. Other experts thought WTO’S warnings were useful.
D. The volcanic ash was more dangerous than cigarette smoke or pollution.
3. The underlined word “hysterical” in Paragraph4 most probably means        .
A. amazing          B. practical        C. valuable            D. overstated
4. What can we learn from the passage?
A. The volcanic ash wouldn’t be harmful to people.
B. All experts thought the volcanic ash did great harm to our health.
C. People close to the volcano would likely be at risk according to some experts.

B. When I have to learn a new word, I write down the word and its meaning in the back of my notebook. Then I make sure to use the word at least 7 times in the next week. I put a check next to the word each time I use it to be sure. This way I can remember that word better.
C. I sit in the front of the classroom. That way there are no distractions between me and the teacher. The further back you sit, the more kids there are in front of you who can distract you.
D. I watch my teachers carefully for clues about what’s most important. Some start moving around a lot, some raise their voice, and some start moving their hands about. When this happens, I write down what they’re saying in my notebook.

【小題2】 I can’t concentrate on what the teacher says in class. I sit at the back of the classroom. What the students in the front row do always attracts my attention. I’m wondering if anyone else has the same problem.
【小題3】 It’s impossible to write down everything the teacher says in my notebook. I have been told to take down the important points, but how can I tell which points are important?
【小題4】 I take good notes in class. I’m curious to know how to make good use of these notes to improve my understanding. I’m often confused about how to deal with the notes.
【小題5】 I enjoy studying at home at night or over the weekend. But sometimes I just can’t focus. I think it’s the study environment that makes me not feel like studying. Who can tell me how to improve the study environment?

Each new school year brings fresh reminders of what educators call the summer learning gap. Some call it the summer learning setback. Simply speaking, it means the longer kids are out of school, the more they forget. The only thing they might gain is weight.

Most American schools follow a traditional nine-month calendar. Students get winter and spring breaks and about ten weeks of summer vacation. Some schools follow a year-round calendar. They hold classes for about eight weeks at a time, with a few weeks off in between. The National Association for Year-Round Education says there were fewer than three thousand such schools at last count. They were spread among forty-six of the fifty states.

But many experts point out that the number of class days in a year-round school is generally the same as in a traditional school. Lead researcher Paul von Hippel said, "Year-round schools don't really solve the problem of the summer learning setback. They simply spread it out across the year."

Across the country, research shows that students from poor families fall farther behind over the summer than other students. Experts say this can be prevented. They note that many schools and local governments offer programs that can help.

But calling them "summer school" could be a problem. The director of the summer learning center at Johns Hopkins, Ron Fairchild, said research with groups of different parents in Chicago and Baltimore found that almost all strongly disliked the term summer school”. In American culture, the idea of summer vacation is connected to beliefs about freedom and the joys of childhood. The parents welcomed other terms like "summer camp," "enrichment," "extra time" and "hands-on learning."

On the whole, it’s not something we parents shout about, but one in four of us does it. Hiring private tutors for our children is now widespread.

“It’s expensive, but worth it,” says Ashan Sabri, whose daughter Zarreen, is having tuition in biology and chemistry in preparation for A-levels this summer. “My husband and I tried to tutor her at home, but we found all our knowledge was out of date and we were only confusing Zarreen. We also tried a group revision course but all the children were sitting in a room for different kinds of exams. On the whole, we think one-to-one tuition works best.”

The real reason is: does tutoring do any good?

“It’s not the magic bullet,” says Professor Judith Ireson, author of a 2005 Institute of Education report on the subject. “It’s still up to the child to do the learning. If he or she isn’t interested, sending them to a private tutor won’t do any good. However, we did find that students who had private tuition in mathematics during the two years before GCSE achieved on average just under half a grade higher than students who did not have a tutor.”

In which case, surely it’s time to break open the champagne? Not necessarily, says Elaine Tyrrell, head of The Rowans School, Wimbledon, a preparation school which regularly gets children into the best private schools.

“While we recommend private tutoring for a few children whose first language isn’t English, we don’t encourage it for the others. With the level of education they get here, children really ought to be able to pass the entrance exams without any extra teaching. And our worry is that they might just get used to getting help from last-minute tutoring, but, once they actually get to that school, they won’t be able to cope.”

But Mylene Curtis, owner of Fleet Tutors, one of the biggest tutoring agencies in the country, holds a different view.

“In some respects, the hurdles children have to leap in order to get into these schools are set at a higher level than the reality,” says Curtis. “We often find that, once a child has got into a school, the standard of work isn’t as high as was feared. The trick is to do well enough in the exam to win a place.”

1.What does Ashan Sabri think of the group revision course?

A.It’s expensive but worthwhile because it works the best.

B.It confuses students because the knowledge taught in it is out of date.

C.It isn’t effective because it doesn’t focus on specific exams.

D.It is effective because it doesn’t focus on specific exams.

2. What do the underlined words “magic bullet” in Paragraph 4 mean?

A.Something that cannot help to solve problems at all.

B.Something that solves a difficult problem in an easy way.

C.Something that seems useful but has no use at all.

D.Something that encourages interest in study.

3.According to Elaine Tyrrell, private tutoring is _______.

A.effective in language learning but not for exams

B.effective for foreign students but not for local students

C.unnecessary in most cases and may harm the further study of students

D.unnecessary in secondary school but helpful to further study

4. What can be inferred from the last two paragraphs?

A.Fleet Tutors and the Rowans School are competitors.

B.Entrance exams to schools are too difficult for most students.

C.Further study isn’t as difficult as was first thought.

D.Private tuition is worth the financial investment.

5.What attitude does the author hold towards home tutoring?

A.Critical

B.Objective

C.Supportive

D.Uninterested
