2. The waves were running mountains high and the inky clouds were riven by forked lightning. 波涛汹涌如山，闪电象一把叉子似地划破了漆黑的云层。
3. Nigerian militant groups in the conflict-riven Niger Delta have been handing over weapons as part of a government amnesty which expires on Sunday. 位于阿尔及利亚因冲突而分裂的尼日尔三角洲武装组织正上缴其武器，该行动是政府特赦的一部分，于本周日到期。
