29. Anne:When will the football game start?Bill:In five minutes. ___________ We’re late.(A) Hurry up! (B) Time to go home.(C) Where? (D) It rains in summer.

30. Mark:Hi, Tony. What do you do to keep fit? Tony:____________________ Do you want to go with me? Mark:It sounds like a great idea!(A) It’s not your fault. (B) You are the painters.(C) I’m sure. (D) I swim seven times a week.

複選題12. Which of the following statements are correct? (A) In the classical limit, high temperature or low density, both Bose–Einstein and Fermi–Dirac statistics approach the Maxwell-Boltzmann distribution. (B) Helium-4 atoms obey Fermi-Dirac statistics. (C) Photons obey Bose-Einstein statistics and have a chemical potential equal to zero. (D) Bose-Einstein statistics are commonly used to describe phonons in semiconductors because phonons are integer-spin quasiparticles and their number is not conserved. (E) In heavily doped semiconductors, if the carrier concentration approaches or exceeds the effective density of states, electrons or holes can no longer be described by Maxwell–Boltzmann statistics and must instead be treated using Fermi-Dirac statistics.

複選題13. Which three of the following statements correctly describe the hydrogen atom, the harmonic oscillator, and the particle in a box in quantum mechanics? (A) The energy quantization of a harmonic oscillator obtained from the Schrödinger equation reduces exactly to Planck's quantization formula; however, Max Planck did not provide a physical interpretation for this quantization. (B) For a particle in a two-dimensional box, the numbers of ground and first excited states are identical as long as the box is square. (C) For a harmonic oscillator, the ground-state energy satisfies the lower bound imposed by the Heisenberg uncertainty principle because its wavefunction is Gaussian. (D) For the hydrogen atom, the principal quantum number specifies the total energy and the number of quantum states, while the spatial symmetry of the wavefunction must be further determined by the orbital and magnetic quantum numbers. (E) In all three types of potentials, the wavefunction must vanish at infinity if the particles form a bound state under the influence of these potentials.
