The painters use brown or white sugar as the main 5 . The hot sugar becomes 6 in a short time, so they have to 7 their paintings quickly by using the spoon. Sugar paintings are different from 8 paintings. 9 is difficult to make a sugar painting by using spoons and sugar. So painters who want to be good at caramelized sugar painting always practice normal painting first 10 it can help them practice their drawing skills.
The 11 of sugar painters in Sichuan Province has decreased. It is because children 12 playing computer games rather than learning the folk art. 13 , it is listed as a Provincial Non-material Cultural Heritage(非物质文化遗产). The art now is getting more and more support 14 both the public and the government. I believe that more people will 15 spoons and learn to create caramelized sugar painting in the near future.

A synthesis should contain two parts— restatement and evaluation of one or more sources in one way or another. Read the seven sentences from Highlighting effect: The function of rebuttals in written argument. Decide whether each of the following statements is a RESTATEMENT or an EVALUATION of sources, or BOTH. Pay attention to the italicized parts. ? Toulmin (1958) suggested that arguments simply including my-side reasons are inadequate to be persuasive. The true persuasive arguments are those taking account of the other-side’s point of view.
A、restatement
B、evaluation
C、restatement and evaluation
D、none

An analog signal is sampled, quantized and encoded into a binary PCM wave. The number of representation levels used is L=32768. A synchronizing bit is added at the end of each codeword representing a sample of the analog signal. The resulting PCM wave is transmitted over a channel of bandwidth BT=28 (kHz), using a binary PAM system with raised-cosine spectrum, where the roll-off factor is a=0.75. Then, the information is transmitted at the rate Rb=____ (bps) through the channel. The analog signal is sampled at the rate fs= (Hz). The maximum possible value for the highest frequency component of the analog signal is fH= (Hz).
A、Rb=32k, fs=2k, fH=1k
B、Rb=32k, fs=4k, fH=2k
C、Rb=48k, fs=2k, fH=1k
D、Rb=48k, fs=4k, fH=2k

An analog signal is sampled, quantized and encoded into a binary PCM wave. The number of representation levels used is 2048. A synchronizing bit is added at the end of each codeword representing a sample of the analog signal. The resulting PCM wave is transmitted over a channel of bandwidth 28kHz, using a 8-ary PAM system with raised-cosine spectrum, where the rolloff factor is 0.75. Then, the information is transmitted at the rate Rb=____ (bit/s) through the channel. The analog signal is sampled at the rate fs=___(Hz). The maximum possible value for the highest frequency component fH of the analog signal is fh=__ (Hz).
A、Rb=96k, fs=8k, fh=4k
B、Rb=48k, fs=8k, fh=4k
C、Rb=96k, fs=16k, fh=8k
D、Rb=48k, fs=16k, fh=8k
第7题
A、A Polyvinyl chloride
B、B Polyurethanes
C、C Polyesters
D、D PMMA
