2- Read the following passage, then answer the questions:
At an elevation of 29,035 feet (8850 meters), Mount Everest is the world‟s largest
mountain. Mount Everest is relatively young, having been formed only 60 million years
ago, and it is still growing a few millimeters every year! Mount Everest is in the
mountain range called the Himalayas. The summit ridge of Mount Everest separates
Nepal and Tibet. Each of these two countries has a special name for this giant mountain.
The Nepalese name is „Sagarmatha‟, which means „goddess of the sky‟. The Tibetan
name is „Chomolungma‟, which means „mother goddess of the universe‟. In English,
Mount Everest is named after Sir George Everest, the first person to record the height and
location of the mountain. A climb to the summit was attempted by George Mallory in
1922, who famously gave his reason for wanting to climb Everest as, “Because it‟s
there”. He attempted to reach the summit again in the company of Andrew Irvine in
1924, but it was on this trip that both climbers disappeared. The first successful ascent of
Mount Everest was accomplished by Sir Edmund Hillary and Tenzing Norgay on May
29, 1953. The first ascent by a woman was on May 16th, 1975, by Junko Tabei from
Japan. Between 1921 and 2001, more than 1400 people have climbed Mount Everest.
Since the first ascent in 1953, more than 600 climbers from 20 different countries have
reached the summit. However, at least 170 climbers have died attempting to climb Mount
Everest, most commonly from avalanches, but also from falls in crevasses, cold, or high-
altitude sicknesses.

A-In what way does Mount Everest change every year?
a) It is shrinking a few millimeters.
b) It is getting thinner.
c) It is moving sideways.
d) It is growing a few millimeters.
B- List at least two ways in which climbers have died on Mount Everest.

 

3- Translate into Arabic:
The desert is one of the most difficult environments in the world to travel
through. The sand dunes are difficult to climb and the temperatures are very high.

 

4- Translate into English:
تعطي الذولت المصرٍت اهتماما كبَرا إلقامت المشروعاث وبناء المصانع الضخمت في سَناء وصعَذ مصر والوادً
الجذٍذ وتقدم كل التسهيالت الممكنة لرجال االعمال العرب واالجانب الستثمار اموالهم فى مصر.
