The Guardian1. British scientists are preparing to launch trials of a radical new way to fight cancer, which kills tumours by infecting them with viruses like the common cold.

If successful, virus therapy could eventually form. a third pillar alongside radiotherapy and chemotherapy in the standard arsenal against cancer, while avoiding some of the debilitating side-effects.

Leonard Seymour, a professor of gene therapy at Oxford University, who has been working on the virus therapy with colleagues in London and the US, will lead the trials later this year. Cancer Research UK said yesterday that it was excited by the potential of Prof Seymour"s pioneering techniques.

One of the country"s leading geneticists, Prof Seymour has been working with viruses that kill cancer cells directly, while avoiding harm to healthy tissue. "In principle, you"ve got something which could be many times more effective than regular chemotherapy," he said.

Cancer-killing viruses exploit the fact that cancer cells suppress the body"s local immune system. "If a cancer doesn"t do that, the immune system wipes it out. If you can get a virus into a tumour, viruses find them a very good place to be because there"s no immune system to stop them replicating. You can regard it as the cancer"s Achilles" heel."

Only a small amount of the virus needs to get to the cancer. "They replicate, you get a million copies in each cell and the cell bursts and they infect the tumour cells adjacent and repeat the process," said Prof Seymour.

Preliminary research on mice shows that the viruses work well on tumours resistant to standard cancer drugs. "It"s an interesting possibility that they may have an advantage in killing drug-resistant tumours, which could be quite different to anything we"ve had before."

Researchers have known for some time that viruses can kill tumour cells and some aspects of the work have already been published in scientific journals. American scientists have previously injected viruses directly into tumours but this technique will not work if the cancer is inaccessible or has spread throughout the body.

Prof Seymour"s innovative solution is to mask the virus from the body"s immune system, effectively allowing the viruses to do what chemotherapy drugs do - spread through the blood and reach tumours wherever they are. The big hurdle has always been to find a way to deliver viruses to tumours via the bloodstream without the body"s immune system destroying them on the way.

"What we"ve done is make chemical modifications to the virus to put a polymer coat around it - it"s a stealth virus when you inject it," he said.

After the stealth virus infects the tumour, it replicates, but the copies do not have the chemical modifications. If they escape from the tumour, the copies will be quickly recognised and mopped up by the body"s immune system.

The therapy would be especially useful for secondary cancers, called metastases, which sometimes spread around the body after the first tumour appears. "There"s an awful statistic of patients in the west ... with malignant cancers; 75% of them go on to die from metastases," said Prof Seymour.

Two viruses are likely to be examined in the first clinical trials: adenovirus, which normally causes a cold-like illness, and vaccinia, which causes cowpox and is also used in the vaccine against smallpox. For safety reasons, both will be disabled to make them less pathogenic in the trial, but Prof Seymour said he eventually hopes to use natural viruses.

The first trials will use uncoated adenovirus and vaccinia and will be delivered locally to liver tumours, in order to establish whether the treatment is safe in humans and what dose of virus will be needed. Several more years of trials will be needed, eventually also on the polymer-coated viruses, before the therapy can be considered for use in the NHS. Though the approach will be examined at first for cancers that do not respond to conventional treatments, Prof Seymour hopes that one day it might be applied to all cancers.

听力原文：Tutor: Come in, everyone. The office might be a bit crowded with four of us and all these materials! There's coffee over there---help yourselves. ... Now, we're here to discuss three types of learners--kinaesthetic, visual and auditory--and how we can teach each type. I gave each of you one of them to consider. Jack, can we look at yours first, please. You were assigned kinaesthetic learners, weren't you?

Jack: Yes, I was. The first idea I had was using gestures, particularly finger gestures. Teachers can use them to emphasise stress on certain syllables. They can also use their fingers to write words in the air--spelling out the letters. The second thing is that the teacher can use the board. The teacher can ask students to spell words by going to the board and writing them up. The teacher could also ask students to write a letter each, in order. The teacher could put a poster on the board and students could go to the board with labels and label it as directed by the teacher. Another possibility is to ask students to organise words into categories on the board.

Tutor: Good. The important thing is to keep kinaesthetic learners active-- moving.

Helen: Games are good for them. Jack, did you think of any?

Jack: Yes, Helen. I thought of a couple. One is like charades. Divide the students into two or three teams. Give the students on one team some words and ask them to act them out. For example, if the word is 'cold', a student might shiver. The other teams have to guess the words.

Tutor: Good idea. Simple, but effective. Well done. Tina?

Tina: Well, I was asked to think about teaching visual learners. Flash cards are good in my opinion. The students can guess words from seeing part of the flash card--which can be a word or a picture--or the teacher can show students the flash cards very quickly. Maybe that's how flash cards got their name! Flash cards can also have different background colours depending on which part of speech they are-- noun, verb, adjective, adverb, etc. Students could also learn from their peers by highlighting words they don't know, in a text for example, then asking ... helping each other with unknown words.

Jack: I know a good game for visual learners. Make a set of cards--half with words on and half with pictures. The cards are face down and students can mm over two at a time. If the word and picture match, they keep the cards. If they don't, they mm them face down again and the next student tries.

Tutor: Great idea. Visual learners are often good at categorising words. Each page in the student's notebook refers to a category of words. Students write new words on the correct page in their notebook for faster recall. For example, page one might be food and page two could be telephone phrases.

Tina: Spider diagrams are good too.

Tutor: Yes, they are. Helen, you were assigned auditory learners.

Helen: OK. I had these ideas for teaching auditory learners. First, they could listen to a dictation and draw what they hear. For example, students listen to the teacher describing items of furniture and then draw them in the appropriate rooms of the house. Or the teacher could describe a picture. After the description, the teacher and students can see whose picture was closest to the original. Flash cards can also be used. Each student gets a flashcard and they hold up their card when they hear that word or phrase in a song, poem or story. Another way of using them is to go around the class, with each student adding a sentence to a story, including the word on their flash card.

Tutor: Auditory learners can also learn using songs and music. Any suggestions?

Tina: The teacher could give the students a text of a song, you know, the lyrics, with some words replaced by a rhyming word. Students then listen to the song and make corrections.

Tutor: That's a really good idea. Perfect for auditory learners. Well, thank you for your suggestions. I have a few other ideas you might con
