I suddenly thought we didn't need any of the junk, and we abandoned all of those, saving $300. That got me thinking about all our pointless expenses in life. With a promise that we'd stop if it was killing us, I convinced the family to take the leap into frugality . The rules were that we would buy nothing for 30 days except absolutely essentials. Our adventure began with a great start. By 9 a.m., my wife, Ruth, had already made cakes from old strawberries and picked flowers I didn't even know we had in the garden. I cleared the car by hand for the first time for years. I read and returned the neighbor's newspaper before he woke up. Total spending on the first day: $0. As days turned into weeks, we became so proficient at living frugally. We started riding our bikes to save gas. My child's finger painting was recycled as gift wrap for the homemade presents. We started to use an Internet application like Skype for free phone calls and ask neighbors with gardens for extra vegetables and herbs. In the end, we saved more than $2000 by not spending for a month. When we began, I imagined we would rush out the moment we were done and buy a lot of things in the supermarket, then maybe hit the mall or go to the movies. Question: How many things were mentioned about the things the family did to save on the first day of the "30 days"? Options: A: Two. B: Three. C: Four. D: Five.

Even tumours that resist treatment with the best medicines on the market, including the "wonder drug" Herceptin, may surrender to the vaccine. The experiments so far have been on mice - but researchers hope to pilot the drug on people within two years. If all goes well, the vaccine could be on the market by 2020. Rather than attacking cancer cells, like many drugs, the new treatment arouses the power of the immune system to fight tumours. The search for vaccines has been prevented by fears that healthy tissue would be destroyed along with tumours. Researchers from the University of Georgia and the Mayo Clinic in the US focused on a protein called MUC1 that is made in bigger amounts in cancerous cells than in healthy ones.Not only is there more of it, but a sugar that it is "decorated" with has a distinctive shape. The vaccine trains the immune system to recognise the rogue sugar and turn its weapons against the cancer. "Cancer cells have a special way of thwarting the immune system by putting sugars on the surface of tumour cells so they can travel around the body without being detected," researcher Professor Sandra Gendler said. "To enable the immune system to recognise the sugar it took a special vaccine that had three parts to it. "She said it was this that "turned out to be a winning combination". Question: How does the vaccine treat fatal cancers? Options: A: It employs the power of the immune system to fight cancerous cells. B: It deprives a protein called MUC1 of its sugar. C: It attacks cancer cells like many drugs D: It destroys tumors along with healthy tissue

Q: Read the article and select the best answer. Article: The other day I heard a few local musicians talking: "I hate all the pianos in this town and I hate that rubbish they play on the radio. They cannot even understand rhythm .""Nobody wants to pay musicians anything. I'm sick of all the people who want you to play without paying you."... One younger musician said, "There are a couple of clubs who want me to play for a few nights a month, and I'm trying to find other places to play. I'm also planning to join in several summer festivals this year." I really liked what the younger musician said so I made friends with him. Attitudes are important. Whether they're positive or negative , they're all rubbing off on you. If you're around people who are always complaining or blaming others, it is possible that you will start doing the same as well. If you spend lots of time with people who don't support your dreams, it is time to take a look at the people you call "friends". There is an easy exercise you can try. Make a list of the people who you often stay with, and simply stop spending time with the negative people on your list. Set a new standard for yourself and don't become friends with people who fall below that standard. The choice is always yours to make. Of course, this exercise is entirely different from making friends only for the good of oneself. We really should try to help and spend time with those who are working towards a goal or dream. Question: The musicians' conversation at the beginning is to show that _ . Options: A: musicians' living conditions are not good B: people in that town have poor taste in music C: different people have different attitudes D: young people are more likely to succeed
A: C

Q: Read the article and select the best answer. Article: Gauri Nanda sees a wearable computer as a handbag -- one that's built out of four-inch squares and triangles of fiber, with tiny computer chips embedded in it. It looks, feels and weighs like your typical leather purse. That's where similarities end: This bag can wirelessly keep track of your belongings and remind you, just as you're about to leave the house, to take your wallet. It can review the weather report and suggest that you grab an umbrella. This purse can even upload your favorite songs onto your scarf. Sure, a computing purse and scarf set may seem like the stuff of science fiction. But these devices, part of next generation of wearable computers, could become commonplace within a few years. DuPont created new super strong fibers that can conduct electricity and can be woven into ordinary-looking clothes. And the chipmaker developed chip packaging allowing wearable computers to be washed, even in the heavy-duty cycle. As a result, these new wearable devices are different from the heavy and downright silly versions of the recent past, which often required users to be wrapped in wires and type on their stomachs. Unlike their predecessors, these new wearable computers also make economic sense. When her bag becomes commercially available in two to three years, Nanda expects it will cost around $150, which is the price of an average leather purse. Here's how the bag works: You place a special radio-signal-transmitting chip on to your wallet. A similar radio in your purse picks up the signal and notifies you that you've forgotten to take your wallet. In turn, sensors on your purse's handles will notify the computer that you've picked up the purse and are ready to go. _ Indeed, more people will want to cross that bridge in the coming years -- making for a booming market for wearable computers that don't like something out of science fiction. Question: Which of the following describes a wearable computer? Options: A: It can be washed in a washing machine. B: It is much heavier than a leather purse. C: It can download songs from the Internet. D: It is made of clothes conducting electricity.
A: A
