Dos and Don’ts for USA Travel

Despite what difficult procedures (程序) you may have endured to get to the U.S., including visa troubles, airport security screenings, and the like, the United States is a rather relaxing place once you arrive. 1. Following are basic tips about traveling in the USA.

Don’t try to see and do too much.

2. Many foreign visitors to the United States try to see New York, Washington DC, Miami, and Los Angeles all in one trip. That kind of touring can leave a traveler very tired if you have limited vacation days. The best way is to focus on a region and more deeply.

3.

While traveling in the United States, do be sure to smile, ask questions, say “please” and “thank you”, and be patient. In almost all cases, your kindness will be rewarded by locals who want to show you the best of their cities and towns.

Do obey traffic signs and laws.

Traveling outside of the United States, I have noticed that stop lights and “No Parking” signs in some parts of the world are only suggestions for drivers. Not in America. Drivers must come to a full stop at a red light and remain stopped until the light turns green. 4.

Do be on time.

America take punctuality very seriously. 5. Give yourself more time than you think you’ll need to get to some place, especially if you’re not familiar with the area as unexpected delays can happen, such as heavy traffic.

A. It is considered rude to be late.

B. Besides, drivers should obey the speed limit.

C. Do be kind, smile, and enjoy yourself.

D. Don’t assume you can smoke anywhere.

E. The United States is larger than Europe.

F. Try to use the vocabulary they use in their everyday life.

G. But we do have a few rules that foreign visitors may not know about.

Whether you want to improve your writing skills as a creative writer or simply perfect your skills for schoolwork, you can take some steps to learn how to be a better writer.

1. Use active instead of passive voice.

In English, the most basic sentence structure is S-V-O: Subject-Verb-Object. The passive voice usually requires more words and use of a “to be” verb form, which can suck the energy out of your writing. Learn to avoid these constructions as much as you can. 1. It conventionally uses the passive voice to put the emphasis on the results, rather than the researchers.

2. 2.

Finding the right verb or adjective can turn an uninspired sentence into one people will remember and quote for years to come. Look for words that are as specific as possible. Strong doesn't mean obscure, or more complicated. Don't say "utilize" when you could say "use." 3.

3. Cut the chaff.

4. You don't get points for saying in 50 words what could be said in 20, or for using multi-syllable words when a short one does just as well. It might feel good at first to pack a lot of ideas and details into a single sentence, but chances are that sentence is just going to be hard to read. If a phrase doesn't add anything valuable, just cut it. 5. If you notice that your writing is filled with "-ly" words, it might be time to take a deep breath and give your writing more focus.

A. Use strong words.

B. Show, don't tell.

C. Good writing is simple, clear and direct.

D. The main exception to this is science writing.

E. Cutting the chaff is best done at the editing stage.

F. "He sprinted" is not necessarily better than "he ran."

G. Don't write "screamed fearfully" -- "scream" already suggests fear.

The health problems about cloned animals , particularly those who appear healthy but have hidden illnesses or problems that appear unexpectedly later in life, have the potential to cause real risks to the safety of the food products from those animals. Ian Wilmut, a lead scientist involved in the creation of Dolly, the first cloned animal, has warned that even small imbalances in a clone’s hormone, protein, or fat levels could bring its milk or meat into danger.

As part of its risk assessment on animal cloning, the Food and Drug Administration (FDA) concluded that milk and meat from cloned animals and their offspring (后代)are as safe to eat as products from conventional animals. The FDA further announced that it would not require food products from cloned animals or their offspring to be labeled as such.

Consumer watchdog groups pointed out that the FDA’s analysis was based on limited data supplied mainly from the cloning companies themselves. In addition, while food safety is an obvious concern of consumers, it is not the only issue that makes people uncomfortable with animal cloning. For example, surveys indicate that 63 percent of consumers would not buy food from cloned animals even if it were labeled as “safe”. Concerns about the morality of cloning, as well as concerns for animal welfare, lead a big majority of people to oppose cloning animals for food. However, these issues were not considered by the FDA. Without labels to identify cloned foods, consumers who oppose animal cloning would be forced to make purchases against their principles without knowing. Consumers have a right to know how their food is produced so they can make informed decisions about what they buy and what they feed their families.

A. Approving. B. Cautious.

C. Uncertain. D. Indifferent.

2.What does the underlined word “such” in Paragraph 2 refer to ?

A. consumers didn’t believe what the FDA said

B. the FDA took consumers’ concerns seriously

C. consumers were well-informed about the safety of food

D. the FDA forced consumers to buy things they didn’t want
