【题目】Babies who watch TV are more likely to show late learning development and language at 14 months, especially if they are watching programs aimed at adults and older children, according to a new study, which would probably surprise those parents who leave their babies in front of a TV set.

Babies who watched 60 minutes of TV daily had developmental scores a third lower at 14 months than babies who were watching less TV. Although their developmental scores were still in the normal range, the difference may have been due to the fact that when children and parents are watching TV, they are missing the talking, playing and other communications that are important to learning and development.

This new study, which appeared in the Aechives of Pediatric and Adolescent Medicine, followed 259 lower-income families in New York, most of whom spoke Spanish as their primary language at home. Other studies of higher-income families have also come to the same conclusion: TV watching is not only non-educational, but it seems to slow down babies’ development.

But what about “good” TV, like Sesame Street? The researchers didn’t find any difference when compared to non-educational programs designed for small children, like Spongebob SquarePants. Earlier research by some of the same scientists, most of whom are at New York University School of Medicine’s Bellevue Hospital Centre, has found that parents whose children watch non-educational TV programs like Spongebob SquarePants spend less time reading to their children or teaching them.

At this point, parents reading this will probably be astonished. TV is so often a parent’s good friend, keeping children happily occupied(占时间)so that the adults can cook dinner, answer the phone, or take a shower. But, clearly, this electronic babysitter(保姆)is not an educational aid. It is best to make sure the babies are fast asleep if you have to watch TV.

【题目】Who doesn’t have a clingy friend? You know, that person who often calls, texts, and e-mails. He often needs your attention, your feedback, or your help. Worse yet, he often gets antsy when you don’t reply immediately.

Is there ever a moment when you just want to turn off your phone and be alone? But you won’t do that to a friend. Actually there are better ways to deal with a clingy friend.

Give Yourself Some Time

If you really need some time for yourself, or you’re just tired of being the listener, just explain to your friend honestly that you want or need some time of your own. Even the most determined friends will understand and give you some space. Of course, those extremely clingy friends will still call, text, and e-mail. If that happens, just reply gently that you need some time for yourself.

Suggest an Activity for Your Friend

If you are tired of different get-togethers and outings, then you should advise your friend to do something alone. If you both like sports, you could tell your friend to have a try at the new gym. If your friend likes your suggestion, but insists that you go along, just explain that you’ve already visited the gym. Mention that you enjoy the gym. If you’re lucky , he’ll try it, and like it.

Introduce Your Clingy Friend to Others.

Your clingy friend may just be lonely or have trouble meeting new people. If that’s the case , introduce him to others with similar interests. He may just make some new friends.

【题目】Unlike chemists and physicists, who usually do their experiments using machines, biologists and medical researchers have to use living things like rats. But there are three Nobel prize-winning scientists who actually chose to experiment on themselves all in the name of science, reported The Telegraph.

1. Werner Forssmann (Nobel prize winner in 1956)

Forssmann was a German scientist. He studied how to put a pipe inside the heart to measure the pressure inside and decide whether a patient needs surgery.

Experiments had been done on horses before, so he wanted to try with human patients. But it was not permitted because the experiment was considered too dangerous.

Not giving up, Forssmann decided to experiment on himself. He anaesthetized (麻醉) his own arm and made a cut, putting the pipe 30 centimeters into his vein. He then climbed two floors to the X-ray room before pushing the pipe all the way into his heart.

2. Barry Marshall (Nobel prize winner in 2005)

Most doctors in the mid-20th century believed that gastritis was down to stress, spicy food or an unusually large amount of stomach acid. But in 1979 an Australian scientist named Robin Warren found that the disease might be related to a bacteria called Helicobacter pylori.

So he teamed up with his colleague, Barry Marshall, to continue the study. When their request to experiment on patients was denied, Marshall bravely drank some of the bacteria. Five days later, he lost his appetite and soon was vomiting each morning he indeed had gastritis.

3. Ralph Steinman (Nobel prize winner in 2011)

This Canadian scientist discovered a new type of immune system cell called the dendritic cell. He believed that it had the ability to fight against cancer.

Steinman knew he couldn’t yet use his method to treat patients. So in 2007, when doctors told him that he had cancer and that it was unlikely for him to live longer than a year, he saw an opportunity.

With the help of his colleagues, he gave himself three different vaccines based on his research and a total of eight experimental therapies(疗法). Even though Steinman eventually died from his cancer, he lived four and a half years, much longer than doctors had said he would.

【1The main purpose of the passage is to ________.

A. present some dangerous experiments that Nobel prize winners did on themselves.

B. list difficulties that scientists went through in order to make important discoveries.

C. explain why some scientists chose to experiment on themselves.

D. introduce a few Nobel prize winners who did experiments on themselves.

【2】 Which of the following is TRUE according to the article?

A. Forssmann’s experiment ended in failure.

B. Forssmann had the pipe pushed all the way into his heart.

C. Barry Marshall succeeded by drinking some Helicobacter pylori.

D. Barry Marshall’s experiment on himself confirmed that most doctors’ belief about gastritis was correct.

【3The underlined word “gastritis” in Paragraph 5 probably means ______.

A. a kind of bacteria B. a kind of stomach disease

C. a new type of therapy D. a large aount of stomach acid

【4From the text, we can conclude that Ralph Steinman ______.

A. discovered a new type of cancer cell called the dendritic cell

B. tried different therapies containing the dendritic cell on himself

C. had his request to experiment on patients denied

D. believed that he was better than doctors at treating cancer
