Article: A new concept vehicle, Pod was introduced by Toyota and Sony at the Tokyo motor show. The car is intended as a four-wheeled friend. It aims to provide affection, sympathy and encouragement. Like a dog welcoming its master, the car sits up, wags its tail and acknowledges its owner's presence using hydraulics and a multi-coloured LED display panel across the front. While on the road, the car constantly monitors the driver's mood with pulse and sweat sensors on the joystick . Cameras focused on the eyes keep watch for any sigh of _ . If a driver appears to be losing his or her cool, Pod will display warnings, play soft music and blow cold air at the face. Drivers are shaken awake with loud music and a shaking chair. To improve driving skills, Pod uses a comparison to score drivers, offer advice and rank all Pod owners. Toyota claims that the car will eventually be able to learn its owner's likes and dislikes by monitoring passenger conversations. If the car hears a favorite song being discussed, it will download the track from the Internet and play it without being asked. It will also recommend restaurants that might suit the driver's taste and take photographs of passengers when they sound particularly happy. In keeping with the moodiness that is the car's main selling point, Pod expresses a form of road anger. If a driver brakes or swerves suddenly, the LED panel shows an angry red and the tail rises at the back. Anger is one of the car's ten "emotional states". Another is sadness --- a blue front with tear-shaped lights seemingly dropping from headlights --- which appears after a flat tire or when gas is low. "We wanted to show that the cars can be cheerful and entertaining," said Yasunori Sakamoto, part of the Toyota design team. Mr Sakamoto said Toyota has no plans to put Pod on the market. Sad, really.
Question: According to the text, Pod can _ .
Options: (A) rank the restaurant nearby (B) recommend a song to passenger (C) have a conversation with drivers (D) test the driver's driving skills
D

Article: The first Ml choir rehearsal of the school year took place in the school hall. All the students joined together to sing. I watched as my elder sister and her grade came in and took their places next to us on the stage. Meanwhile, I could hear laughing. Some students were pointing at a girl standing next to my sister. I'd never seen this girl before. A girl whispered in my ear, " Did you know she's wearing diapers ?" After school that evening, I asked my sister about the girl I'd seen. She told me her name was Theresa and that she was a very nice girL ." Why were those kids being mean to her? I asked, "Because they're stupid," she said. One day, I was walking home from school when I heard voices behind me. "There's the little idiot's sister. Does your sister wet her pants too?" I walked a little faster and then I felt a atone hit me in the back. When I got home, I ran down to my sister's room. I pushed my way into her room, screaming at her. "Why do you have to be that giri's friend? I don't see anyone else being nice to her, " Janelle yelled back, Because she is a wonderful person and she is dying!" I will remember those words as long as I live. Theresa wet her pants because she had an illness, which was killing her. My sister was the only one nice enough to be her friend and stick up for her. A few months later, Hieresa passed away. I felt proud that Janelle was my sister. Throughout the years I watched her, and she always made friends with everyone. It didn't matter if they ware fat, thin, brilliant or not. She never left anyone feeling isolated or alone. It was she who changed me and taught me to never look at anyone in the same way again.
Question: Why did other students make fun of Theresa?
Options: (A) Because she was dying very soon. (B) Because she was not good at singing, (C) Because she behaved in an unusual way. (D) Because she was usually dressed poorly.

Article: Because I will be away for a few days after Spring Break, I am writing this during the actual holiday, when I can use time to catch up on a number of purely administrative items. First of all, you should have received the letter I sent out on April 2 advising of the transition arrangements to new leadership at ISM (International School of Moscow). In that letter I pointed out that Dr. Paul Malone will be arriving in Moscow on Monday, May 4th, and that I will work with him during that week to ensure smooth transition. My last day at ISM will be Friday, May 8th. Several people have asked me why I required Dr. Malone to come early. There are many problems facing ISM at the moment which have major implications for the future, and it makes sense for the new director to come aboard before the end of the school year. This will give him the chance to play a major role in the planning process for 2014--2015 and beyond. The fact that Paul Malone is able to arrive in early May is good for the school. I have been working closely with him, and will do everything possible to see that he can move in easily when I leave. From here I will go to Hong Kong for a couple of weeks to spend time in my new situation, and then I will return to the United States for a few weeks' vacation. In the most recent edition of the Compass(a kind of paper of ISM), I wrote briefly what I consider to be the major challenge for ISM in the future. I am sure that the new leadership of the school will be able to face those challenges in an active manner, which will ensure a strong future for the school. I shall certainly watch the progress of the school with interest. The results of the school for the past few years have been quite outstanding, and I fully expect that level of performance to continue.
Question: We can infer from the text that the writer was the _ of ISM.
Options: (A) director (B) employee (C) teacher (D) student
A
