When the time came for Gallaudet to (48) America, he asked Clerc to come with him. The two men (49) in June 1816. The voyage (50) the Atlantic (大西洋) took days. They put the time to productive use, (51) for the new school for the deaf (52) they wanted to ’open. Such a school was (53) the following year in Connecticut.

It’s 8.00 am. James Butters gives ]8-month-old Thomas his milk, then breakfast. After getting Thomas into his outdoor clothes, they head for the park to watch birds and play on the grass. With hitch time drawing near, they’re back home for an afternoon of drawing, playing with cars, maybe watching some children’s programs.

James isn’t Thomas’ dad. He is a nanny (保姆)--a man nanny, obviously, interestingly termed a "manny"--specially trained and in his third nannying position. At 27, he cares for Thomas, and another boy of a similar age. "It’s much freer than an office job," he says, "and you’re getting to see children develop and grow. You become very close to them, for sure. I don’t think I’m special or better than a woman nanny; everyone has their own method. But I’m unusual. Friends laughed when I started studying nursery nursing. In my class, I was the only man among 70 women. Somehow, I made it," he said.

Although it’s not yet common to find men in traditional (传统的) nannying courses, things are changing. In the United States, parents are employing young mannies, sometimes to care for babies, but more often as active role models to get junior away from the TV and the computer. From rollerblading (轮滑) friends to summer swimming mannies, these are the big brothers who are always willing to play, largely because they’re paid for it.

It is catching on here in Britain, too. Earlier this year, Nofland nanny college welcomed its first full-time man student, 19-year-old Peter Cummins in Wales. While some families find it difficult to accept the idea of a young man in a traditional nannying role, man nannies are increasingly popular.

As it turned out, I (9) the new car. It ran beautifully, all the tires were good, (10) I happily stopped buying gas every week. Our teenage children were (11) to ride around in a small green car (12) a smoky van (小型客货车). It began to feel like our family’s car.

Still, I (13) looking in the rear-view mirror (后视镜) and seeing the seats (14) I used to put my little children. I still thought about the family (15) in that car and the fun we had together.

The Northern Pike is a very bad fish. It is a big, hungry fish, and eats little fish. Many Northern Pike live in Lake Davis. They are killing all the smaller fish in the lake. The Northern Pike area serious danger to the lake because they eat all the smaller fish. Soon, all other kinds of fish in the lake will be killed off. This is not healthy for the environment (环境).

Researchers are afraid that the Northern Pike will swim out of Lake Davis through many smaller rivers that feed into the lake. They could spread all over the country and damage many other water environments. If that happens, it would be too late to stop the Northern Pike.

For ten years, officials have been trying to remove the Northern Pike from Lake Davis. They have tried using nets and poisons (毒). However, the Northern Pike population is still doing well in Lake Davis. Many people do not like the idea of using poison to kill the fish. They worry that the poisons are bad for humans who use the water. However, people haven’t found any poisons at all in local (当地的) wells.

Scientists are going to try the poison again. This time, they will dry off the lake before putting the poison in. A public hearing will be held to talk about the problem.

Mobile Phone Manners

Mobile phones have changed the way we communicate (交流); they have also brought about problems in phone manners (礼仪). Gaik Lira, a Singapore-based advisor, has some advice on phone manners.

When dealing with missed calls, the person being called should return the call. "Calls should be returned as soon as possible, and no later than the following day. Anything later than that, and an apology or a reason for the delay should go with the call. "

Text messages should be kept short and to the point. If they go beyond four or five lines, call or e-mail instead. "The use of short forms should be among family members and friends, never in a business situation. "

Speak in a low voice as if you were talking to someone next to you. If the connection is bad, don’t raise your voice in order to be heard, simply move to another place where the connection may be better. And if that doesn’t work, tell the caller to call you back or offer to call at a later time.

When a conversation is cut off due to a bad connection, the person who started the conversation should call back. "It may be inconvenient for the other person to return the call, especially if it’s an unlisted number, or an overseas call. "

When running late for a date or meeting, it is acceptable to text to inform that you’ll be delayed. Messages should be apologetic. "A message like ’ Sorry. Will be about 30 minutes late due to flight delay’ is considered polite and thoughtful. "

Taking calls during meetings is only acceptable if you have informed the chairperson that you are expecting an urgent (紧急的) call. If you get an unexpected but urgent call, apologize to those present and offer a quick explanation as to why you have to take that call. Then leave the room to continue your phone conversation.
