【1】 The first type involve people getting together to work on a project, for example, Wikipedia. Blogs and micro-blogs (such as Twitter) are another type of social media. There are other websites like YouTube that allow people to share content such as pictures, articles or videos. Another type of social media are social networking sites.【2】 Facebook is an example of this type. Many people like to play games on the Internet and, yes, there are social media games as well.

22、 Chicago Doctor Invents Affordable Hearing Aid
Superb Performance From Affordable Digital Hearing Aids
Board certified Ear, Nose, and Throat physician Dr. Cherukuri has done it once again with his newest invention of a medical grade, ALLDIGITAL, affordable hearing aid.
Dr. Cherukuri knew that untreated hearing loss could lead to depression, social isolation, anxiety, and symptoms consistent with Dementia and Alzheimer’s disease In his practice he knew that many of his patients would benefit from new digital hearing aids but many couldn’t afford the expense, which is not generally covered by Medicare and most private health insurance policies.
Same Technology as $3, 500 Hearing Aids
He evaluated all the high-priced digital hearing aids on the market and then created his own affordable version-called MD Hearing Aid AIR for its virtually invisible, light weight appearance. This doctor designed digital hearing aid delivers clear sound all day long and the soft flexible ear domes are so comfortable you won’t realize you are wearing them.
This new digital hearing aid is packed with the features of $3,500 competitors at a small part of the cost. Now most people with hearing loss are able to enjoy crystal clear, natural sound-in a crowd, on the phone, in the wind-without “whistling” and annoying background noise.

23、A farmer had a cow. He took very good care of this cow and one day when it was ill, he was very worried. He telephoned the vet.
“What’s the problem?” The vet asked him when he arrived.
“My cow’s ill,” the farmer said. “I don’t know what’s the matter with her. She’s lying down and won’t eat. She’s making a strange noise.”
The vet looked over the cow. “She’s certainly ill,” he said, “and she needs to take some very strong medicine.”
He took a bottle out of his box, put two pills into his hand and said, “Give her these. The pills should make her better.”
“How should I give them to her?” the farmer asked.
The vet gave him a tube (管子)and said, “Put this tube in her mouth, then put the pills in the tube and blow. That’ ll make it.”
The next day the vet came to the farm again. The farmer was sitting outside his house and looked more worried.
“How’s your cow?” the vet asked.
“No change,” the farmer said, “and I’m feeling very strange myself.”
“Oh?” the vet said, “Why?”
“I did what you said,” the farmer answered. “I put the tube in the cow’s mouth and then put two pills down it.”
“And?” the vet asked.
“The cow blew first,” the farmer said.

24、Imagine a simple blood test that could flag most kinds of cancers at the earliest, most curable stage. Liquid biopsies could, in theory, detect a tumor (肿瘤) well before it could be found by touch, symptoms or imaging. Blood tests could avoid the need for surgeons to cut tissue samples and make it possible to reveal cancer hiding in places needles and scalpels cannot safely reach. They could also determine what type of cancer is taking root to help doctors decide what treatment might work best to destroy it.
Liquid biopsies are not yet in hand, because it is hard to find definitive cancer signals in a tube of blood, but progress in recent years has been impressive. Last year the journal Science published the first big prospective study of a liquid biopsy for DNA and proteins from multiple types of cancers. Though far from perfect, the blood test called CancerSEEK found 26 tumors that had not been discovered with conventional screenings.
Liquid biopsies can rely on a variety of biomarkers in addition to tumor DNA and proteins, such as free-floating cancer cells themselves. But what makes the search difficult, Ana Robles, a cancer biologist of the National Cancer Institute, explains, is that “if you have an early-stage cancer or certain types of cancer, there might not be a lot of tumor DNA,” and tests might miss it. The ideal blood test will be both very specific and very sensitive so that even tiny tumors can be found. To tackle this challenge, CancerSEEK looks for cancer-specific mutations (突变) on 16 genes, and for eight proteins that are linked to cancer and for which there are highly sensitive tests.
Simple detection is not the only goal. An ideal liquid biopsy will also determine the likely location of the cancer so that it can be treated. “Mutations are often shared among different kinds of cancer, so if you find them in blood, you don’t know if that mutation is coming from a stomach cancer or lung cancer,” says Anirban Maitra, a cancer scientist at the Anderson Cancer Center. To solve that problem, some newer liquid biopsies look for changes in gene expression. Such changes, Maitra notes, are “more organ-specific”.
On the nearer horizon are liquid biopsies to help people already diagnosed with cancer. Last year the government approved the first two such tests, which scan for tumor DNA so doctors can select mutation-targeted drugs. Scientists are working on blood tests to detect the first signs of cancer recurrence (复发) in patients who have completed treatment. This work is moving fast, but does it save lives?
That is the question companies such as Thrive and Grail must answer for their broadly ambitious screening tests. “These companies have to prove that they can detect early cancer and, more important, that the early detection can have an impact on cancer survival,” Maitra observes.
【1】According to the passage, liquid biopsies are expected to
A.flag cancer and determine the treatment
B.detect cancer signals from a sample of blood

【3】The author is mostly concerned about whether .
A.liquid biopsies can discover tumors conventional screenings can’t find
B.liquid biopsies can improve the application of mutation-targeted drugs
C.liquid biopsies can help save the lives of those with cancer
D.liquid biopsies can be developed for cancer prevention
