We arranged that Kissinger would fly to Vietnam early in July and then stop in Pakistan on the way back. There he would develop a stomachache that would require him to stay in bed and not be seen by the press. Then, with President Yapha's help, he would be taken to the airport where a Pakistani jet would fly him over the mountains to China. Kissinger's trip was given the name Polo after Marco Polo, another Western traveler who made history by journey in China. Everything went quite smoothly. His slight illness in Islamabad received only small attention from reporters covering him. They accepted the story that he would be kept shut up for at least a few days and began making arrangements for their own activities. Because of the need for complete secrecy and the lack of any direct communication facilities between Beijing and Washington, I knew that we would have no word from Kissinger while he was in China. Even after he had returned to Pakistan, it would still be important to keep it secret, so before Kissinger left, we agreed on a single code word - Eureka - which he would use if his missions were successful and the presidential trip had been arranged. On July 11, Al Haig, who knew our code work, phoned to say that a cable from Kissinger had arrived. "What's the message?" I asked. "Eureka". he replied. Washington would have no word from Kissinger while he was in China, mainly because _ . A) the trip must be kept secret B) president Yapha would not fly together with Kissinger C) communication between China and Islamabad was impossible D) Al Haig would phone to the author to tell him about Kissinger's trip

See a cellphone cover that you like on Taobao? Forget about placing an order, paying the bill online and waiting for days for it to be delivered to you. In the near future, you'll be able to get it in minutes just by hitting "print" on your computer. You might find it hard to believe that you could actually "print" an object like you would a picture. But it is not that hard to understand how it would work. Just as a traditional printer sprays ink onto paper line by line, modern 3D printers spread material onto a surface layer by layer, from the bottom to the top, gradually building up a shape. Instead of ink, the materials the 3D printer uses are mainly plastic, resin and certain metals. The thinner each layer is--from a millimetre to less than the width of a hair--the smoother and finer the object will be. This may sound like a completely new technology, but the truth is that 3D printing has been around since the late 1980s. Back then, it was barely affordable for most people, so few knew about it. Last year, though, saw a big change in the 3D printing industry--printers became much cheaper. For example, 10 years ago a desktop 3D printer might have cost PS20,000, while now they cost only about PS1,000, according to the BBC. Taken out of the factory and introduced to more diverse and common uses, 3D printing can create just about anything you can think of--flutes , bikinis, jewelry, aircraft parts and even human organs. In fact, scientists from Cornell University in New York have just made an artificial ear using a 3D printer, according to Science Daily. The fake ear looks and acts exactly like a natural one. However, as 3D printing becomes more common, it may bring about certain problems--such as piracy. "Once you can download a coffee maker, or print out a new set of kitchen utensils on your personal 3D printer, who will visit a retail store again?" an expert in 3D printing told Forbes News. Even more frightening, what if anyone in the world could use a 3D printer to print out a fully functioning gun? According to the article, in the future, the 3D printing technology will _ . A) enable people to make better purchases online B) change the way we make many products C) be applied as widely in our daily life as computers D) shorten the time it takes for people to get what they buy online

Q: One should be moderate ( ) in all things. Moderation is always the safest way to do things, and a virtue we should have. Let's take the student life for example. There are some students who study too hard and play too little, while there are others who play too much and study too little. On the one hand, it is harmful to his health if he has too few physical exercises, and on the other hand, it is harmful to his mind if he plays too much. In the matter of eating, one also should be moderate. Do not eat too much or too little. Too much eating will make you sick, while too little eating will make you weak. The man of progress is he who neither has too high an opinion of himself nor thinks too poorly of himself. If he thinks too highly of himself, he is surely to become very proud, but if he has too poor an opinion of himself, he will have no courage to make an advance. Both the conditions above will make you lose your aim in life. A broadminded man is he who always moves within the orbit of reasonableness . In any activities in one's life, moderation is one of the best ways to enjoy real happiness. A man of progress should_himself. A) have a moderate opinion B) think highly of C) look down upon D) think both highly and poorly of

*Question*
Tanzania Tarangire is a national Park which lies in Tanzania. The park itself covers an area of around 2,850 square kilometers, making it the sixth largest park of its kind in the country. I recently visited Tarangire to see what it was like.... One of the first sightings upon entering the park which I found was a huge herd of elephants. Our guide told us that Tagrangire was probably the best place in Tanzania to find large herds of elephants, and that their population in the park was around 2,500. We continued to watch the elephants as they stood under trees and scratched themselves against the trees to hit the spot of an itch . To the right of the elephant herd, we noticed a big tree! Our guide informed us that this was a Baobab tree and that they could live for hundreds of years. Compared with this tree, the elephant just looked like dwarfs ! We were informed that Tarangire was one of the best National Parks in Africa to see so many Baobab trees. As we continued our drive through the park, we finally reached a watering hole. Our guide warned us that there were lions all around us. It took us all a while to find them, but there they were! Most of them are resting in the shade under brushes, but there was one that was drinking from the watering hole directly in front of us. We then noticed just to our right, there were a couple of fresh zebra corpses -- it seemed as if the lions which were resting had killed them! We were unlucky not to have seen the actual kill, as our guide had mentioned that the zebra corpses were fresh and the kill had occurred within the last hour. Our final big sighting was one that none of us were expecting to see, even our guide! We pulled over to where there was a large gathering of cars, with a sleeping leopard there! We took photos happily and excitedly and observed its surprising body before returning to our hotel as it was getting late. So, I hope you enjoyed my description of Tarangire, and that I have inspired you to add this amazing park to your very own Tanzania travel route. What does the writer think of his trip in Tanzania Tarangire? A) Boring B) Challenging C) Dangerous D) Enjoyable
