Question 1:C

Question 2:B

Question 1: Test and analysis: China's photovoltaic products are mainly sold to the European Union and other countries, and the European Union has conducted a double-reverse investigation on China's photovoltaic products, which has caused heavy losses to China's photovoltaic industry. This enlightens us that we should implement the diversification strategy of export market to reduce the market risk brought by trade friction, and C is correct; Cooperation and development are the mainstream of world economic development, and trade protectionism is a tributary. A is wrong. BD doesn't match the meaning of the question.

Question 2: Analysis of test questions: China resolutely opposes the unfair taxation measures taken by the European Union on photovoltaic products exported from China to Europe, which shows that China unswervingly safeguards China's national interests in its foreign relations; China attaches great importance to its strategic partnership with the EU, because the trade friction in the photovoltaic industry will affect the overall situation of China-EU relations, so it is in the common interest of China and the EU to cancel the double-opposition policy. (1) is inconsistent with the meaning of the question; Maintaining world peace and promoting common development are the aims of China's foreign policy. So choose B for this topic.
