【题目】When tea was first brought to England between 1652 and 1654, it was so expensive that only the rich could buy it. It was said that an old couple had some sent to them as a great treat. But they did not know how it ought to be used. Eventually they boiled the leaves, put some of them on a piece of bacon for dinner, ate the leaves, and threw the tea soup away. However, tea quickly proved popular enough to replace ale（麦芽酒）as the national drink of England after King Charles II and his Portuguese wife began to follow this foreign tea tradition.

Before the introduction of tea into Britain, the English had two main meals — breakfast and dinner. Breakfast was ale, bread and beef. Dinner was a long, massive meal at the end of the day. It was no wonder that Anna, the Duchess of Bedford (1788 — 1861) experienced a “sinking feeling” in the late afternoon. So she invited friends to join her for an additional afternoon meal at five o’clock in her castle. The menu centered around small cakes, bread and butter sandwiches, and, of course, tea. This summer practice proved so popular that the Duchess continued it when she returned to London, sending cards to her friends asking them to join her for “tea and a walking the fields”.

The practice of inviting friends to come for tea in the afternoon was quickly picked up by other social hostesses. A common pattern of service soon came into practice. The first pot of tea was made in the kitchen and carried to the lady of the house who waited with her invited guests, surrounded by fine porcelain（瓷器）from China. The first pot was warmed by the hostess from a second pot (usually silver) that was kept heated over a small flame. Food and tea was then passed among the guests, the main purpose of the visiting being conversation.

【题目】2014 saw that the Ebola virus reappeared in Guinea and soon spread into neighbouring Liberia and Sierra Leone, killing over 7,800 people by the new year of 2015. It leads to viral hemorrhagic fever, which is characterized by high fever and internal bleeding etc.

Ebola is named after the Ebola River, where it was first discovered in 1976. There are five different types of the Ebola virus, each named after where they first happened: Sudan, Ivory Coast, Reston, Bundibugyo, and Zaire. The deadliest of the five, Zaire, was responsible for the 2012 out- break, and is believed to be attacking Guinea.

Ebola is naturally found in fruit bats, which pass on the virus to other animals by biting or sucking on their blood. Humans who are suffering from the Ebola infection might have touched the bodily fluids of the infected animals. Once infected, a human becomes a carrier of the deadly virus.

Unfortunately, there are no disease - specific treatments for Ebola. Health - care workers only supply the infected people with physiological saline（生理盐水）to keep them in good condition. Ebola can kill 90% of those infected, especially in underdeveloped societies like those in Africa. Since there have been many cases of nurses catching the disease from patients, they are forced to wear strict protective clothes, and in some cases, not even allowed to get close to the infected. The fact that there is no cure for the Ebola virus is what makes the outbreak a challenging one to control.

What’s worse, since we live in an interconnected world, where the situation in one country can affect us all, the influences of Ebola are huge: damaging trade relations, affecting foreign visitors, and weakening entire countries. It is feared that the disease may spread throughout west African countries. For every country, a strong health system can decrease the risk of health attack and lessen the impact of Ebola.

A. It has caused a panic in many countries.

B. It is the most dangerous virus in the world.

D. Anyone who was infected Ebola will die.

A. What the Ebola virus is
