1.The traffic on the main streets has a longer green signal than _______ on the small ones.(  )
A.oneB.thisC.thatD.it

分析 句意:主干道路的绿色交通信号灯的时间要长于其他小干道的信号灯.

解答 答案C.
这里需要代词指代the traffic,而that特指不可数名词,例如Few pleasures can equal that of a cool drink on a hot day.这句中that指代a cool drink,One泛指可数名词单数;it指代前文出现的事物,this指代前文提到后文还接着出现的可数名词单数.故选C.

点评 考查代词的辨析,要掌握代词的用法,根据语法意义以及语境来选择合适的答案.

Even in the fanciest pizza restaurant, you will never feel weird if you ask for a box to take your leftovers (剩饭)home. In Italy, that will soon apply everywhere, with a new law that encourages restaurants to give people doggy bags, although in Italy it's called a "family bag."

The new law is designed to reduce food waste and open doors to companies wishing to donate wasted food. Family bags were made to avoid embarrassment at asking for leftovers, turning it from begging into good behavior.

In the U.S., taking uneaten food home is normal. In the U.K. it is fairly common. To the south, though, this practice is rare. In Spain and Italy, people might take the bones from their meat and give them to their dogs, but culturally, it's not the done thing. Also, there aren't often many leftovers, as dishes are sized according to how much people will actually eat and are rarely too big to finish unless you over-order.

In France, the laws are tougher. Last year, the French began to forbid supermarkets to throw away food. They must either give it away to charity, or make it available to be used as animal feed and compost(堆肥),If they fail to follow the law, they will be fined.

Perhaps Italy's new law is right. Food waste is now attracting international attention, but the only way to really stop it lies in whether individuals are willing to change their ways. If it becomes socially unacceptable to waste food, or to serve a huge portion in restaurants, then we have a chance.

1.What does the underlined word “weird” in paragraph 1 probably mean?

A. Difficult. B. Strange

C. Relaxed. D. Disappointed.

2.Why do the Spanish seldom take leftovers home from restaurants?

A. They don’t bother to do it.

B. It is their custom to eat food up.

C. It is not acceptable in their culture.

D. They usually order small portions.

3.According to the author, how can we reduce food waste?

A. By introducing stricter laws.

B. By donating food to the needy.

C. By restaurants only serving small portions.

D. By everyone taking action and saying no to it.

4.What’s the text mainly about?

A. Way of reducing food waste.

B. Italy’s plans to use family bags.

C. How doggy bags come into being.

D. The increasingly serious food waste.
