【題目】Having taken a room at the hotel at which he had been instructed to stay, Smallwood went out; it was a lovely day, early in August, and the sun shone in an unclouded sky. He had not been to Lucerne since he was a boy, but remembered a covered bridge, though not clearly, a great stone lion and a church in which he had sat, bored yet impressed while they played an organ (風(fēng)琴); and now wandering along a shady quay (碼頭) he tried not so much to find his way about a half-forgotten scene as to reform in his mind some recollection of the shy and eager boy, so impatient for life, who so long ago had wandered there. But it seemed to him that the most lively of his memories was not of himself, but of the crowd; he seemed to remember the sun and the heat and the people; the train was crowded and so was the hotel, the lake steamers were packed and on the quays and in the streets you found your way among the holiday-makers. They were fat and old and ugly and strange.

Now, in wartime, Lucerne was as deserted as it must have been before the world discovered that Switzerland was the play-ground of Europe. Most of the hotels were closed, the streets were empty, the boats for hire rocked (搖晃) lazily at the water’s edge and there was none to take them, and in the avenue by the lake the only persons to be seen were serious Swiss taking their dogs for their daily walk. Smallwood felt happy and, sitting down on a bench that faced the water, surrendered (聽任) himself to the feelings. The blue water, snowy mountains, and their beauty hit you in the face. So long, at all event, as the fine weather lasted he was prepared to enjoy himself. He didn’t see why he should not at least try to combine pleasure to himself with advantage to his country.

【1】We can infer that Smallwood went to Lucerne _________.

A. to enjoy the beautiful scenery of the area

B. to do something as told

C. to visit his friend there

D. to get in touch with the shy and eager boy

【2】He felt that the city _________.

A. was more crowded than it used to be

B. had changed out of all recognition

C. had been ruined by becoming an attraction

D. was quieter than he remembered it

【3】He was prepared to enjoy himself as long as _________.

A. he was serving his country

B. he was making a profit

C. the pleasant weather continued like this

D. he could stay in Lucerne

【4】After reading the passage, we can draw a conclusion that _________.

A. Smallwood’s former visit to Lucerne was made in peacetime

B. Smallwood was pleased by the sound this time

C. Smallwood was very nervous when he got to Lucerne

D. A war would soon break out in Lucerne

【題目】Some people view a bad situation as a disaster. It’s not. It’s an opportunity. Once your old world collapses(倒塌), you can recover and rebuild. Now you have the chance to start fresh and do things more intelligently. I built my business on an unstable structure. I kept it going for years, but the business collapsed last year. I had to leave my office, selling off all the furniture and equipment. I got kicked out of my apartment because I couldn’t pay the rent. I couldn’t pay my bills or debt. I declared bankruptcy.(破產(chǎn))

For years there was the worry that this might happen if I didn’t keep straining（盡力） to keep the business going. And my worries were right. What I worried about would happen did happen .But you know what? Going through that experience wasn’t really so bad. It was interesting. Some of it was actually pretty easy. Throughout most of it, I felt increasing relief and a renewed sense of freedom and possibility. All the old baggage was gone. No more office. Fewer possessions. Fewer obligations. No more debt. Most of all , no more straining. Life became a lot easier.

I got a cheaper and smaller apartment. I became debt-free. I learned to live within my means. Those were actually good things. The others were just feelings. The reality wasn’t actually painful. After that, I kept going with the same business but completely changed the business model. I avoided the earlier mistakes, and that business recovered just fine and worked great. It was profitable every year from then on. But I had to go through the collapse first to reach that point.

If you’ve been feeling out of control with your current work or lifestyle, and you’re currently straining to keep it going ,consider letting it go. Try allowing the old world to collapse, many or all of your fears and worries might actually come to pass, but that’s ok. You don’t have to keep the old world alive. If it keeps falling apart on you ,let it collapse. Experiencing the collapse isn’t as bad as fearing the collapse

A. the freedom and possibility of refreshing himself
