Section D
听力原文： The fourth component of the Swedish social system is that its policies ensure full employment and increase the mobility of labour—that is, the ability to change jobs without losing income. Swedes have a strong work ethic. This, combined with state-funded programmes that minimise unemployment, results in a policy of subsidised employment, which Sweden prefers to high unemployment rates and large welfare expenditures. So, there are a large number of vocational training programmes that employers pay for available to workers in jobs that have become unnecessary. There are also subsidies for workers who must change jobs because of changes in the labour market.
Sweden introduced the fifth and final component of its social system at the end of the 20th century. This component corrects some of the problems created by the four previously mentioned components. It includes new rules that are designed to improve job stability, such as training programmes to help employees learn new skills as their jobs change and become more complex. Also, the government has reduced social insurance and welfare payments.
So, in conclusion, the Swedes are happy with their system. Sweden has achieved more in terms of social equality, economic security and freedom than many other economies. As a result, most Swedes aren’t interested in any more reform. of the economic system. However, because it is heavily involved in international markets, Sweden must continue to manage its social policies so that it remains competitive in the international marketplace.

Translate into Chinese： (1)If the input to a linear system is a sinusoidal wave, the output will also be a sinusoidal wave, and at exactly the same frequency as the input. (2)Just as we can express any signal as the sum of a series of shifted and scaled impulses, so too we can express any signal as the sum of a series of (shifted and scaled) sinusoids at different frequencies. (3)A signal is formally defined as a function of one or more variables that conveys information on the nature of a physical phenomenon. (4)Nyquist sampling theorem states that if the highest-frequency component of a CT signal x(t) is fmax, then x(t) can be recovered from its sampled sequence x(nT) if the sampling frequency fs is larger than 2fmax. (5) In fact, if a discrete-time sequence is absolutely summable, then its spectrum is, as in the continuous-time case, a bounded and continuous function of ω. (6) Systems are defined to be stable if every bounded input excites a bounded output. The condition for discrete-time systems to be stable is that all poles of H(x) lie inside the unit circle on the z-plane.
