Q: Read the following article and select the best answer. Article: I have always known my kids use digital communications equipment a lot. But my cellphone bill last month really grabbed my attention. My son had come up to nearly 2,000 incoming text messages, and had sent nearly as many. Of course, he was out of school for the summer and communicating more with friends from a distance. Nevertheless, he found time to keep a summer job and complete a college course in between all that typing with thumb. I was even more surprised to learn that my son is normal.

Some experts regret that all that keyboard jabber is making our kids stupid, unable to read non-verbal cues such as facial expressions, gestures, posture and other silent signals of mood and attitude.

I have found him more engaged and easier to communicate with from a great distance. because he is constantly available by means of text message and responds with faithfulness and speed.

Tu delivered a speech titled Artemisinin is a Gift from TCM to the World. She has urged more research into the benefits of traditional Chinese medicine and called for joint efforts worldwide to fight against malaria and develop more potential uses for TCM, which she called a "great treasure" with thousands of years' history and empirical knowledge.

According to the WHO, more than 240 million people in sub-Saharan Africa have benefited from artemisinin, and more than l. 5 million lives are estimated to have been saved since 2000 thanks to the drug.
