In particular, we give a new proof of the result of Hasse, asserting that in this case h(d) = 1 is possible only if d is of the form p, 2q or qr. where p.q. r are primes and q≡r≡3(mod 4).展开更多

We contest that methods now widely in use at colleges and universities are insufficient to reach modern nationwide targets. We suggest modifications in teaching approach and present ideas for supplementing and enlivening existing materials or replacing them. Much of the article is drawn from our converging experiences both as a Chinese university teacher of English from one aspect and as an English EFL specialist from another. We speak jointly from the ’chalkface’ and wish to share our views and be provoked into seeking solutions to the new challenges for Chinese EFL inherent in targets set by the national standards.展开更多

文摘We investigate arithmetic properties of certain subsets of square-free positive integers and obtain in this way some results concerning the class number h(d) of the real quadratic field Q(√d). In particular, we give a new proof of the result of Hasse, asserting that in this case h(d) = 1 is possible only if d is of the form p, 2q or qr. where p.q. r are primes and q≡r≡3(mod 4).
文摘Introduction In this article we discuss making use of applied linguistic theory, as the means of achieving national standards at tertiary level. We contest that methods now widely in use at colleges and universities are insufficient to reach modern nationwide targets. We suggest modifications in teaching approach and present ideas for supplementing and enlivening existing materials or replacing them. Much of the article is drawn from our converging experiences both as a Chinese university teacher of English from one aspect and as an English EFL specialist from another. We speak jointly from the ’chalkface’ and wish to share our views and be provoked into seeking solutions to the new challenges for Chinese EFL inherent in targets set by the national standards.
