Dear Mr. White,

I heard that you are planning to invite a famous scientist to give us a speech, so I¡¯m writing to ask whether we can have a speech given by Professor Martin Karplus.

Born on March15, 1930, Professor Martin Karplus is an Austrian-born American theoretical chemist. He works as a professor of chemistry at Harvard University.

I have two reasons for asking for him to give us a speech. One is that the Karplus equation is named after him, and the other is that he received the 2013 Nobel Prize in Chemistry, together with two other colleagues.

Thank you for reading my letter. I hope you can consider my suggestion seriously.

Yours sincerely,

Li Hua

¡¾ÌâÄ¿¡¿A little old couple walked slowly into McDonald¡¯s on one cold winter evening. It seemed that they didn¡¯t come to the right place with the young families and young couples eating that night.

The little old man walked right up to the cash register£¬I placed his order with no hesitation and then paid for their meal. The couple took a table near the back wall and started taking food off the tray. There was one hamburger£¬one order of French fries and one drink. The little old man unwrapped the plain hamburger and carefully cut it in half. He placed one half in front of his wife. Then he carefully counted out the French fries£¬divided them in two piles and neatly placed one pile in front of his wife. He took a sip at the drink and then set the cup down between them.

As the man began to eat his few bites of hamburger£¬the crowd began to get restless. You could tell what they were thinking£¬¡°That poor old couple. All they can afford is one meal for the two of them.¡±

As the man began to eat his French fries£¬one young man stood and came over to the old couple¡¯s table. He politely offered to buy another meal for the old couple to eat. The old man replied that they were just fine. They were used to sharing everything.

As the little old man finished eating and was wiping his face neatly with a napkin£¬the young man could stand it no longer. Again he came over to their table and offered to buy some food.

After being politely refused again£¬he finally asked a question of the little old lady£¬¡°Ma¡¯am£¬why aren¡¯t you eating£¿You said that you share everything. What is it that you are waiting for?

She answered£¬¡°The teeth.¡±

¡¾1¡¿Who were eating in McDonald except the old couple that night? (No more than 8 words)

¡¾2¡¿What did the old man order? (No more than 12words)

¡¾3¡¿Why did the young man offer to buy some food for the old couple? (No more than6 words)

¡¾4¡¿What can we learn from the old lady¡¯s answer? (No more than 5 words)

¡¾ÌâÄ¿¡¿The young boy was sitting on the ground in the refugee(ÄÑÃñ)camp playing with an empty tin£®Other children were standing around watching him with envious eyes£®

Envy? Of an empty tin?

This tin was indeed no worthless piece of trash¡ªit was a splendid truck£¬complete with wheels and grille(ÌúÕ¤) and floor£®The vehicle even had remote control£¬a frayed piece of string from the¡°engine¡±to the hand of the owner£®

The tin had lost all its original markings£®But its first load had probably been sardines(ɳ¶¡Óã)£®Later the tin had been left with other rubbish behind the refugee camp clinic£¬and the boy had found it on one of his daily expeditions into the¡°big world¡±£®

For thousands of refugee children£¬a tin 1ike this rates high on their list of wants£®It can be used for many purposes£¬as jewellery£¬as a toy£¬for drinking or as a medicine box£®

Many refugee children would consider it the happiest day of their lives if they received a handful of marbles(µ¯Öé) as a present£®

They dream of gifts which children in developed countries take for granted£®Maybe a book to read£®or a pencil and an exercise book of their very own£®

Their imagination can create toys£¬but it cannot create books£®Someone else must provide them£®A more costly and valuable gift they cannot imagine£®

¡¾1¡¿How do you think the youn eel when he gets something to read?

A. depressed B. frustrated

C. excited D. frightened

¡¾2¡¿Other children envied the young boy because the boy £®

A£® had something to play with B£®got some sardines to eat

C£®received a handful of marbles D£®had a real truck toy

¡¾3¡¿What is implied in the last paragraph of the text?

A£®The society should donate(¾è)some toys for the refugee children

B£®The refugee children are more imaginative rather than creative

C£®The refugee children are more creative rather than imaginative

D£®The society should offer the refugee children things for study

¡¾4¡¿Which of the following would be the best title for the passage?

A£®An Enviable Toy Present B. Sardine Tin¡ªA Precious Toy

C£®A Splendid Truck Toy D£®A Poor Refugee Cam
